In this description, the term proximal is generally used to indicate relative nearness of a referenced item to a user of the device and the term distal is used to indicate relative remoteness of a referenced item to a user of the device.
FIG. I illustrates a blood collection device 10 having a safety shield apparatus 12 mounted thereon and a removable sheath 14 positioned about a needle 16 (FIG.
2) of collection device 10. Blood collection device 10 includes a blood collector barrel 1 I which
7 defines a cylindrical chamber 18 which is dimensioned to receive a blood collection vial (not shown). A proximal end of needle 16 (not shown) is positioned within cylindrical chamber 18 and is configured to pierce a stopper supported on one end of the blood collection vial.
As shown in FIGS. lA and 113, blood collector barrel 11 includes a finger flange l la, a pair of spaced extensions or towers 11b and a nose l lc. Nose llc defines a throughbore lld (FIG. 1B) which is dimensioned to receive and frictionally retain needle 16 (FIG. 2) therein. In one embodiment, finger flange 11 a is dimensioned or of a size to facilitate creation of a positive seal between a proximal face 13 (FIG. 1) of finger flange 11 a and a peelable lid 11 Id (FIG1) secured to proximal face 13 of finger flange 11 a.
Peelable lid 11 d can be secured to finger flange 11 a using an adhesive or the like and can function to prevent dust or debris from entering cylindrical chamber 18 or as a sterile barrier which assures sterility of cylindrical chamber 18.
Spaced extensions llb are positioned on opposite sides of nose llc and include recesses 11 e (FIG. 1B) which will be discussed in further detail below. The inner walls at the distal end of extensions 11b define surfaces 11 f for frictionally engaging a proximal flange 14a of sheath 14 to secure sheath 14 about needle 16. At least one of extensions 11 b includes a land/indentation/depression/recess 1 l g defming a location where a heated tool can be applied to heat stake flange 14a of sheath 14 to at least one of extensions 11 b, thereby securing sheath 14 to barrel 11. The heat stake provides the clinician with an indication that device 10 is new or unused and that sheath 14 has not previously been removed or tampered with.
Each extension 11 b may include fmger gripping sections 11 h (FIG. 1) defined by an area of ridges, ribs, knurling, roughness, etc. Finger gripping sections 11h provide the clinician with relatively increased gripping, manipulating and holding ability of blood collector barrel 11 and, in turn, device 10. Turning momentarily to FIGS. IA
and 1B, in an alternate embodiment, the outer surface of each extension llb may be smooth or non-knurled.
With continued reference to FIG. 1, each extension llb may include a camming surface, cut-out, recess or the like lle formed in a distal-most corner thereof. Camming surface I 1 e functions to aid in the removal of sheath 14 from barrel 11. In particular, in use, to remove sheath 14 from barrel 11, sheath 14 is rotated with respect to barrel 11 (as
As shown in FIGS. lA and 113, blood collector barrel 11 includes a finger flange l la, a pair of spaced extensions or towers 11b and a nose l lc. Nose llc defines a throughbore lld (FIG. 1B) which is dimensioned to receive and frictionally retain needle 16 (FIG. 2) therein. In one embodiment, finger flange 11 a is dimensioned or of a size to facilitate creation of a positive seal between a proximal face 13 (FIG. 1) of finger flange 11 a and a peelable lid 11 Id (FIG1) secured to proximal face 13 of finger flange 11 a.
Peelable lid 11 d can be secured to finger flange 11 a using an adhesive or the like and can function to prevent dust or debris from entering cylindrical chamber 18 or as a sterile barrier which assures sterility of cylindrical chamber 18.
Spaced extensions llb are positioned on opposite sides of nose llc and include recesses 11 e (FIG. 1B) which will be discussed in further detail below. The inner walls at the distal end of extensions 11b define surfaces 11 f for frictionally engaging a proximal flange 14a of sheath 14 to secure sheath 14 about needle 16. At least one of extensions 11 b includes a land/indentation/depression/recess 1 l g defming a location where a heated tool can be applied to heat stake flange 14a of sheath 14 to at least one of extensions 11 b, thereby securing sheath 14 to barrel 11.

With continued reference to FIG. 1, each extension llb may include a camming surface, cut-out, recess or the like lle formed in a distal-most corner thereof. Camming surface I 1 e functions to aid in the removal of sheath 14 from barrel 11. In particular, in use, to remove sheath 14 from barrel 11, sheath 14 is rotated with respect to barrel 11 (as
8 indicated by arrow "A" of FIG. 1) until at least one wing or flange 14b of sheath 14 engages camming surface I le. Continued rotation of sheath 14 relative to barrel 11, in the direction of arrow "A ', results in flange(s) 14b camming against a respective camming surface 11 e and the movement of sheath 14 in an axial direction away from barrel 11 (as indicated by arrow "B" of FIG. 1) thereby facilitating the separation of sheath 14 from barrel 11. During rotation of sheath 14 relative to barrel 11, the heat state between flange 14a of sheath 14 and extension 11b of barrel 11 is broken as a result of shear forces exerted thereon.
Referring generally to FIGS. 2-7, safety shield apparatus 12 includes a distal segment 20, a proximal segment 22 and a foot or retention member 24. Distal segment 20, which is shown in FIGS. 3A, 3B and FIG. 7, includes a body portion 26 having a distal end 26a and a proximal end 26b. A hinge member 28 is formed integrally with distal segment 20 at proximal end 26b thereof. Altemately, hinge member 28 can be fonned as a separate component from distal segment 20 which is secured thereto. Further, hinge member 28 can be formed as a thinned transition region and act as a living hinge which is integrally formed between distal segment 20 and proximal segment 22. In this embodiment, hinge member 28 includes a pair of outwardly directed pivot members 28a which engage a distal end of proximal segment 22 to pivotally secure distal segment 20 to proximal segment 22 as will be discussed in further detail below. Body portion 26 defines a longitudinal channel 30 which extends through hinge member 28 along the length of body 26 to a distal wall 32 of distal segment 20. Channel 30 is dimensioned and configured to receive needle 16 (FIG. 2).
Body portion 26 has an upper wall 34 (FIG. 3B) which extends from proximal end 26b of distal segment towards distal end 26a. Upper wall 34 terminates at an angled extension or cowl 36. In one embodiment, cowl 36 includes a curved distal end 36a and a proximal end 36b (FIG. 7). While proximal end 36b of cowl 36 is shown as extending linearly with distal end 36a, it is contemplated that proximal end 36b need not extend linearly from distal end 36a but may extend at an angle with respect to distal end 36a.
Alternatively, proximal end 36b of cowl 36 may be replaced by any wall (not shown) extending downwardly from an inner surface of body portion 26 at any location along a length of body portion 26. Cowl 36 is positioned to engage and slide along at least one of nose l lc and needle 16 as safety shield apparatus 12 is moved from a retracted position to an advanced position as will be discussed in further detail below.
Referring generally to FIGS. 2-7, safety shield apparatus 12 includes a distal segment 20, a proximal segment 22 and a foot or retention member 24. Distal segment 20, which is shown in FIGS. 3A, 3B and FIG. 7, includes a body portion 26 having a distal end 26a and a proximal end 26b. A hinge member 28 is formed integrally with distal segment 20 at proximal end 26b thereof. Altemately, hinge member 28 can be fonned as a separate component from distal segment 20 which is secured thereto. Further, hinge member 28 can be formed as a thinned transition region and act as a living hinge which is integrally formed between distal segment 20 and proximal segment 22. In this embodiment, hinge member 28 includes a pair of outwardly directed pivot members 28a which engage a distal end of proximal segment 22 to pivotally secure distal segment 20 to proximal segment 22 as will be discussed in further detail below. Body portion 26 defines a longitudinal channel 30 which extends through hinge member 28 along the length of body 26 to a distal wall 32 of distal segment 20. Channel 30 is dimensioned and configured to receive needle 16 (FIG. 2).
Body portion 26 has an upper wall 34 (FIG. 3B) which extends from proximal end 26b of distal segment towards distal end 26a. Upper wall 34 terminates at an angled extension or cowl 36. In one embodiment, cowl 36 includes a curved distal end 36a and a proximal end 36b (FIG. 7). While proximal end 36b of cowl 36 is shown as extending linearly with distal end 36a, it is contemplated that proximal end 36b need not extend linearly from distal end 36a but may extend at an angle with respect to distal end 36a.
Alternatively, proximal end 36b of cowl 36 may be replaced by any wall (not shown) extending downwardly from an inner surface of body portion 26 at any location along a length of body portion 26. Cowl 36 is positioned to engage and slide along at least one of nose l lc and needle 16 as safety shield apparatus 12 is moved from a retracted position to an advanced position as will be discussed in further detail below.
9 In one embodiment, body portion 26 also includes a lower wall 38 (FIG. 3A) positioned at distal end 26a of distal segment 20. A cam or bearing member 40 which includes an angled surface 40a is formed on lower wall 38. Bearing member 40, as will be discussed in further detail below, reduces or minimizes the likelihood of stalling or binding of safety shield apparatus 12 in its retracted position. An opening or throughbore 41 is formed in distal segment 20 between cowl 36 and lower wall 38.
Referring momentarily to FIGS. 3C and 3D, in an alternate embodiment, a neck portion 28b, interconnecting body portion 26 and hinge member 28, of distal segment 20 may be provided with a strain relief feature in the form of an aperture 28c formed in a surface thereof. Aperture 28c may be any suitable geometry including and not limited to rectangular (where the longitudinal axis of the aperture is axially aligned with a longitudinal axis of the distal segment, or where the longitudinal axis of the aperture is transverse to the longitudinal axis of the distal segment), circular, ovular or the like.
Aperture 28c functions as a stress relief hole, wherein aperture 28c is configured and dimensioned to cause neck portion 28b to structurally fail prior to pivot members 28a failing when forces applied to distal segment 20 exceed a predetermined threshold level.
Additionally, aperture 28c may be configured and dimensioned to cause neck portion 28b to bend prior to pivot members 28a bending when forces applied to distal segment 20 exceed a predetermined threshold level.
Body portion 26 also includes locking tabs 42 (FIG. 4) and a series of ribs 44.
Locking tabs 42 are positioned on opposite sides of distal segrnent 20 for releasably securing safety shield apparatus 12 in its retracted position as will be discussed below. Ribs 44 provide rigidity to distal segment 20.
Referring also to FIGS. 5 and 6, proximal segment 22 includes a body 46 having a distal end 46a and a proximal end 46b. Body 46 includes a top surface 48 (FIG.
6) and a pair of spaced sidewalls 50a and 50b. Spaced sidewalls 50a and 50b define a channel 52 which is dimensioned to receive distal segment 20 when safety shield apparatus 12 is in its retracted position. Channel 52 also allows passage of nose 11 c of blood collection device 10 and needle 16. Distal end 46a of proximal segment 22 includes an opening 56 formed in each sidewall 50a and 50b. Openings 56 are dimensioned to receive pivot members 28a of hinge member 28 (FIG. 3A) to pivotally secure distal segment 20 to proximal segment 22. As discussed above, hinge member 28 and openings 56 may be replaced with a living hinge.
Each sidewall 50a and 50b of proximal segment 22 also includes a cantilevered tab 58 and a cutout 60. Cantilevered tabs 58 are positioned to be received within recesses 11 e of blood collection device 10, as will be discussed in further detail below, to lock safety shield apparatus 12 in an advanced position. Each cutout 60 is positioned to receive a respective tab 42 (FIG. 3B) of distal segment 20 to releaseably secure safety shield apparatus 12 in its retracted position.
In one embodiment, top surface 48 of body 46 of proximal segment 22 includes a thumb engagement member 62 which is ribbed to provide a slip-resistant thumb engaging surface 64. Sidewalls 50a and 50b also include ribs 65 for providing rigidity to sidewalls 50a and 50b of proximal segment 22.
Retention member 24 is monolithically or integrally formed with proximal segment 22 and is hingedly connected to proximal end 46b of proximal segment 22 by a living hinge 66. Alternately, retention member 24 and proximal segment 22 may be formed separately and pivotally attached with a separate hinge member. Retention member 24 includes base portion 68 which defines a mounting hole 70 for securing safety shield apparatus 12 to blood collection device 10 as will be discussed in further detail below. Retention member 24 also includes a distal wall 72, a proximal wall 74 and a pair of sidewalls 76.
Distal wall 72 is integrally connected to living hinge 66 to pivotally secure retention member 24 to proximal .20 segment 22. Proximal wall 74 includes a cantilevered extension 77 which defines a shelf upon which top surface 40a of bearing member 40 rests when safety shield apparatus 12 is in its retracted position. Sidewalls 76 and top and bottom walls 72 and 74 define a box-like structure about base portion 68 to provide strength and rigidity to retention member 24.
Referring momentarily to FIG. 5A, in an alternate embodiment, proximal section may be provided with a rib 76a projecting from a surface of each side wall 76 and extending in a direction substantially parallel to a central axis of mounting hole 70.
In use, when proximal section 22 is secured to blood collector barrel 11, ribs 76a slidably engage (e.g., establish an interference fit with) an inner surface of a respective extension 11b of blood collector barrel 11 (see FIGS. lA and IB), thereby providing increased stability therebetween.
Referring to FIG. 2, in its retracted position, safety shield apparatus 12 is supported on blood collection device 10 such that the longitudinal axes of proximal segment 22 and distal segment 20 are substantially perpendicular to a longitudinal axis of needle 16. In the retracted position of safety shield apparatus 12, tabs 42 of distal segment 20 are releasably positioned within cutouts 60 of sidewalls 50a and 50b of proximal segment 22 to releasably lock safety shield apparatus in its retracted position. Further, top surface 40a of bearing member 40 rests on cantilevered extension 77 of bottom wal174 of retention member 24.
Referring to FIG. 8, safety shield apparatus 12 is moved from its retracted position to its distal position by manually pressing on thumb engaging surface 64 of proximal segment 22 in the direction indicated by arrow "A". As illustrated, thumb engaging surface 64 defines an angled surface such that pressing on surface 64 creates a force having both a horizontal and a vertical component. The vertical component slidably urges top surface 40a of bearing member 40 onto extension 77 of bottom wall 74 of retention member 24. Since top surface 40a is angled as illustrated in FIG. 8, engagement between top surface 40a and extension 77 urges distal end 26a of distal segment 26 outwardly in the direction indicated by arrows "B".
As this occurs, tabs 42 are forced from cutouts 60, distal end 26a moves distally along nose 11 c of barrel 11 and proximal end 26b of distal segment 20 pivots in relation to distal end 46a of proximal segment 22.
In the retracted position of safety shield apparatus 12 for the embodiment shown in FIGS. 2 and 8, cowl 36 is spaced from nose l lc of blood collector barrel 11 and needle 16.
Alternatively, cowl 36 rests against nose 11 c after sheath 14 is removed and assists slidable urging of the distal end 26a of distal segment 26 outwardly in the direction indicated by arrows "B".
Referring to FIG. 9, as safety shield apparatus 12 is moved in the direction indicated by arrow "C" towards its advanced position, top surface 40a of bearing member 14 moves off of extension 77 and a distal edge 36a of cowl 36 of distal segment 26 moves into engagement with needle 16 to guide distal segment 26 along needle 16. As distal segment 26 is moved further distally, an inwardly extending or proximal portion of cow136 moves along needle 16 until only the proximal edge 36b of cowl 36 engages needle 16 when the safety shield apparatus is in its advanced position. See FIG. 10.
As illustrated in FIGS. 11 and 12, as distal segment 26 is moved to its advanced position, cantilevered tabs 58 of proximal segment 22 engage an inner wall of extensions 11b of blood collector barrel 11 and are initially deflected outwardly (FIG. 11) before snapping into recesses 11e of barrel 11 (FIG. 12). Tabs 58 are positioned within recesses l le to lock safety shield apparatus 12 in its advanced position. As illustrated in FIG.
Referring momentarily to FIGS. 3C and 3D, in an alternate embodiment, a neck portion 28b, interconnecting body portion 26 and hinge member 28, of distal segment 20 may be provided with a strain relief feature in the form of an aperture 28c formed in a surface thereof. Aperture 28c may be any suitable geometry including and not limited to rectangular (where the longitudinal axis of the aperture is axially aligned with a longitudinal axis of the distal segment, or where the longitudinal axis of the aperture is transverse to the longitudinal axis of the distal segment), circular, ovular or the like.
Aperture 28c functions as a stress relief hole, wherein aperture 28c is configured and dimensioned to cause neck portion 28b to structurally fail prior to pivot members 28a failing when forces applied to distal segment 20 exceed a predetermined threshold level.
Additionally, aperture 28c may be configured and dimensioned to cause neck portion 28b to bend prior to pivot members 28a bending when forces applied to distal segment 20 exceed a predetermined threshold level.
Body portion 26 also includes locking tabs 42 (FIG. 4) and a series of ribs 44.
Locking tabs 42 are positioned on opposite sides of distal segrnent 20 for releasably securing safety shield apparatus 12 in its retracted position as will be discussed below. Ribs 44 provide rigidity to distal segment 20.
Referring also to FIGS. 5 and 6, proximal segment 22 includes a body 46 having a distal end 46a and a proximal end 46b. Body 46 includes a top surface 48 (FIG.
6) and a pair of spaced sidewalls 50a and 50b. Spaced sidewalls 50a and 50b define a channel 52 which is dimensioned to receive distal segment 20 when safety shield apparatus 12 is in its retracted position. Channel 52 also allows passage of nose 11 c of blood collection device 10 and needle 16. Distal end 46a of proximal segment 22 includes an opening 56 formed in each sidewall 50a and 50b. Openings 56 are dimensioned to receive pivot members 28a of hinge member 28 (FIG. 3A) to pivotally secure distal segment 20 to proximal segment 22. As discussed above, hinge member 28 and openings 56 may be replaced with a living hinge.
Each sidewall 50a and 50b of proximal segment 22 also includes a cantilevered tab 58 and a cutout 60. Cantilevered tabs 58 are positioned to be received within recesses 11 e of blood collection device 10, as will be discussed in further detail below, to lock safety shield apparatus 12 in an advanced position. Each cutout 60 is positioned to receive a respective tab 42 (FIG. 3B) of distal segment 20 to releaseably secure safety shield apparatus 12 in its retracted position.
In one embodiment, top surface 48 of body 46 of proximal segment 22 includes a thumb engagement member 62 which is ribbed to provide a slip-resistant thumb engaging surface 64. Sidewalls 50a and 50b also include ribs 65 for providing rigidity to sidewalls 50a and 50b of proximal segment 22.
Retention member 24 is monolithically or integrally formed with proximal segment 22 and is hingedly connected to proximal end 46b of proximal segment 22 by a living hinge 66. Alternately, retention member 24 and proximal segment 22 may be formed separately and pivotally attached with a separate hinge member. Retention member 24 includes base portion 68 which defines a mounting hole 70 for securing safety shield apparatus 12 to blood collection device 10 as will be discussed in further detail below. Retention member 24 also includes a distal wall 72, a proximal wall 74 and a pair of sidewalls 76.
Distal wall 72 is integrally connected to living hinge 66 to pivotally secure retention member 24 to proximal .20 segment 22. Proximal wall 74 includes a cantilevered extension 77 which defines a shelf upon which top surface 40a of bearing member 40 rests when safety shield apparatus 12 is in its retracted position. Sidewalls 76 and top and bottom walls 72 and 74 define a box-like structure about base portion 68 to provide strength and rigidity to retention member 24.
Referring momentarily to FIG. 5A, in an alternate embodiment, proximal section may be provided with a rib 76a projecting from a surface of each side wall 76 and extending in a direction substantially parallel to a central axis of mounting hole 70.
In use, when proximal section 22 is secured to blood collector barrel 11, ribs 76a slidably engage (e.g., establish an interference fit with) an inner surface of a respective extension 11b of blood collector barrel 11 (see FIGS. lA and IB), thereby providing increased stability therebetween.
Referring to FIG. 2, in its retracted position, safety shield apparatus 12 is supported on blood collection device 10 such that the longitudinal axes of proximal segment 22 and distal segment 20 are substantially perpendicular to a longitudinal axis of needle 16. In the retracted position of safety shield apparatus 12, tabs 42 of distal segment 20 are releasably positioned within cutouts 60 of sidewalls 50a and 50b of proximal segment 22 to releasably lock safety shield apparatus in its retracted position. Further, top surface 40a of bearing member 40 rests on cantilevered extension 77 of bottom wal174 of retention member 24.
Referring to FIG. 8, safety shield apparatus 12 is moved from its retracted position to its distal position by manually pressing on thumb engaging surface 64 of proximal segment 22 in the direction indicated by arrow "A". As illustrated, thumb engaging surface 64 defines an angled surface such that pressing on surface 64 creates a force having both a horizontal and a vertical component. The vertical component slidably urges top surface 40a of bearing member 40 onto extension 77 of bottom wall 74 of retention member 24. Since top surface 40a is angled as illustrated in FIG. 8, engagement between top surface 40a and extension 77 urges distal end 26a of distal segment 26 outwardly in the direction indicated by arrows "B".
As this occurs, tabs 42 are forced from cutouts 60, distal end 26a moves distally along nose 11 c of barrel 11 and proximal end 26b of distal segment 20 pivots in relation to distal end 46a of proximal segment 22.
In the retracted position of safety shield apparatus 12 for the embodiment shown in FIGS. 2 and 8, cowl 36 is spaced from nose l lc of blood collector barrel 11 and needle 16.
Alternatively, cowl 36 rests against nose 11 c after sheath 14 is removed and assists slidable urging of the distal end 26a of distal segment 26 outwardly in the direction indicated by arrows "B".
Referring to FIG. 9, as safety shield apparatus 12 is moved in the direction indicated by arrow "C" towards its advanced position, top surface 40a of bearing member 14 moves off of extension 77 and a distal edge 36a of cowl 36 of distal segment 26 moves into engagement with needle 16 to guide distal segment 26 along needle 16. As distal segment 26 is moved further distally, an inwardly extending or proximal portion of cow136 moves along needle 16 until only the proximal edge 36b of cowl 36 engages needle 16 when the safety shield apparatus is in its advanced position. See FIG. 10.
As illustrated in FIGS. 11 and 12, as distal segment 26 is moved to its advanced position, cantilevered tabs 58 of proximal segment 22 engage an inner wall of extensions 11b of blood collector barrel 11 and are initially deflected outwardly (FIG. 11) before snapping into recesses 11e of barrel 11 (FIG. 12). Tabs 58 are positioned within recesses l le to lock safety shield apparatus 12 in its advanced position. As illustrated in FIG.
10, in the advanced position of safety shield apparatus 12, needle 16 extends along channel 30 such that distal end 16a of needle 16 is positioned behind distal wall 32 of distal segment 26 adjacent lower wall 38.
FIG. 13 illustrates an alternate embodiment of the presently disclosed safety shield apparatus shown generally as 112. Safety shield apparatus 112 is similar to safety shield apparatus 12 and includes a distal segment 120, a proximal segment 122 and a retention member 124. Proximal segment 122 is pivotally secured to distal segment 120 by a thinned transition region or living hinge 126. Safety shield apparatus 112 functions in a manner substantially similar to safety shield apparatus 12 discussed above. Thus, the operation of safety shield apparatus 112 will not be discussed in detail herein.
FIG. 14 illustrates a retaining collar 140 for mounting safety shield apparatus 112 to a blood collection device 110 (See FIGS. 15 and 16). More specifically, retaining collar 140 includes an annular body 142 having an inner annular portion 142a and an outer annular portion 142b joined together by a backspan 142c. Inner annular portion 142a defines a diameter dimensioned to be received about a proximal portion of nose lllc of blood collection device 110.
In order to mount safety shield apparatus 112 onto blood collection device 110, retention member 124, which defines an opening 124a (FIG. 13), is positioned about nose 111 c of blood collection device 110 as illustrated in FIGS. 15 and 16. Next, retaining collar 140 is pressed down over and along nose 111 c to capture retention member 124 between retaining collar 140 and a distal face 111d of blood collection device 110.
The tight interference fit between the inside diameter of retaining collar 140 and the outside diameter of.nose 111 c provides secure attachment of safety shield apparatus 112 to blood collection device 110. It is noted that safety shield apparatus 12 shown in FIGS. 1-12 is mounted on blood collector device 10 using a retaining collar 90. See FIGS. 8-10.
Retaining collar 90 is substantially identical to retaining collar 140.
FIGS. 17-19 illustrate an alternate method and structure for securing a safety shield apparatus 212 to a blood collection device 210. More specifically, blood collection device 210 includes a distal face 210a which includes a plurality of openings 210b.

In one embodiment, projections 212a include a tapered tip and are dimensioned to be press fit into openings 210b to secure safety shield apparatus 212 to blood collector device 210. Although three openings 210b and three projections 212a are illustrated, it is envisioned that one or more openings and projections may be provided, e.g., one, two, four, etc. It is also envisioned that the openings may be formed in the retention member and the projections may be formed on the blood collection device. As illustrated in FIGS. 17 and 18, the assembled device may include a protective sheath 214.
FIGS. 20-22 illustrate yet another method and structure for securing a safety shield apparatus 312 to a blood collection device 310. In this embodiment, retention member 324 of safety shield apparatus 312 includes an opening 324a which defines one or a series of annular recesses and/or ribs or protrusions 330. Nose 311c of blood collector device 310 also includes one or a series of annular recesses and/or ribs 340 which are positioned to mate with annular recesses and/or ribs 330. In this embodiment, opening 324a defines a series of recesses and ribs 330 and nose 311c includes a series of recesses and ribs 340. In order to mount safety shield apparatus 312 to blood collection device 310, retention member 324 is press fit over nose 311c of blood collector device 310 to position recesses and ribs 330 in mating alignment with annular recesses and ribs 340. The interference fit between the annular ribs and annular recesses provides secure attachment of blood collection device 310 and safety shield apparatus 312. It is noted that although ribs and recesses are illustrated as being smoothly curved other configurations are envisioned, e.g., rectangular protrusions and recesses. Further, only recesses may be provided on retention member 324 and protrusions or ribs on nose 311c of blood collection device 310, or vice versa. Moreover, the recesses and ribs need not be engaged in an interference fit, but rather they may be joined in an interlocking fashion.

Raised pads 426d function to create a frictional engagement with a respective inner surface of a side wall 446c of body 446 of proximal segment 422, when safety shield apparatus 412 is in a retracted position, as shown in FIG. 23. The degree of friction or interference between raised pads 426d against the inner surfaces of side walls 446c of body 446 of proximal segment 422 is adjusted based on the dimensions of raised pads 426d (e.g., height, width or thickness) and the distance between side walls 446c of body 446.
As seen in FIG. 24D, distal segment 420 of safety shield apparatus 412 includes a series of ribs 444 disposed on either side of an inner surface thereof and, in turn, define longitudinal channel 430.
