Abstract
137PX SEPARABLE FASTENER FOR CATHETER TUBES AND THE LIKE ABSTRACT OF THE DISCLOSURE A separable fastening device is disclosed to support a catheter tube to a limb of a patient. The fastener has a first flexible strap member including a first knitted textile material having upstanding from one surface a plurality of multifilamentary loop-like elements and a polyurethane foam substrate secured to the opposite surface. A second section is formed of a flexible tape member having upstanding from one surface a plurality of hook-like elements which matingly engage with the upstanding filamentary loop-like elements of the first section so as to be attachable thereto at the respective end portions to form a com-plete flexible strap member. The end portion of the first sec-tion is generally tapered at the connection to the second section and defines an opening therethrough spaced sufficiently from the tapered end and dimensioned to receive a free end portion of the second section. The length of the second section and the rela-tive positioning of the opening in the first section are such as to permit the tapered end portion to be looped about the catheter tube while the second tape section extends therethrough so as to be matingly engaged with the loop-like elements of the first section to secure the catheter tube therein and to attach the entire device in position about a limb of a patient. The poly-urethane material provides a friction surface which grips the tube in a firm, but gentle manner as well as being capable of gripping the human limb to retain the catheter tube in its precis-desired position.

A surface defined by the hooks is merely placed into 13 face-to-ace relationship with a surface defined by the loops so 14 that a large number of hooks engage a large number of loops and therefore are able to resist separation by forces parallel to the 16 interfacial plane of engagement but are readily separable by 17 peeling forces applied substantially normal to this interfacial 18 plane. These fas~ening devices are generally formed of a sheet 19 of synthetic woven or knitted fabric having raised threads of synthetic material, such as nylon, which are napped or unnapped 21 to provide a pile surface defined by a plurality of loops, and 2 which may be thermally treated to become semi-rigid.

In particular, fasteners of khis type have previously 2 ¦ been utilized as strapping devices of various types. Although 3 ¦ the prior art dealing with straps and the like includes numerous ~ fastener devices of various types to secure the straps in their
5 ¦ intended environment, the application$ of these separable hook ¦ and loop-type fasteners have reduced the need or the traditional 7 strap astening devices such as buckles and the like. To the 8 extent that the early fastening devices did not generally facil-9 itate variable and precise fastening, the application of these separable fasteners to the strap art has proven to provide sub-11 stantial advantages.
12 U.S. Patent No. 3,000,384 to Piers, Jr., relates to a 13 fastener tie to retain a hank or loc~ of hair in a desired shape.
14 In an embodiment, a portion of a longitudinally elastic tape is 1~ threaded through the opening of an attached elongated eye in such 1~ a way that the tape forms a spiral-like configuration. U.S.
17 Patent No. 3,297,026 to Van Pelt, relates to a restraining device 18 for holding a limb of an anatomical body. The restraining device lg includes an elongated resiLient pad wrapped around a part of a human limb. U.S. Patent No. 3,726,280 to Lacount relates to 21 a catheter support combining VELCRO~ brand asteners with an 22 elastic band which is secured around ~he patient's thigh. U.S.
23 Patent No. 3,B27,107 to Moore, relates to an adjustable strap 24 assemhly which utilizes VELCROQ brand fasteners in combination with a pad having hooking eleme~ts on both sides to eliminate 2~ the requirement of an excessively long length of looped strap ~7 portion. U.S. Patent No. 3,878,849 to Muller et al., relates 2 to a surgical tube supporter having an elastic strap with a 29 high friction layer on one face to engage the patient's skin.
3 In still another development, a strap adapted to support surgical 11~2~9B
1 tubes is comprised of an elastic strap portion connected at one 2 end to an inelastic strap portion with hook and loop-type fasten-3 er tape members attached thereto at the interface between the elastic and inelastic strap portions. An endless ring-like mem-ber is utilized to loop the hook fastener tape about the surgical tube to pro~ide support therefor.
7 Along with the fastening advantages of the prior art, 8 certain ~isadvantages nevertheless remain, particularly when the 9 fastener device is utilized to support a catheter strap to a patient's limb. For example, in the presently known devices, 11 which utilize elastic bands and the like, there is a tendency to 12 restrict the flow of blood through the encircled human limb and 13 this constriction has been known ~o cause ulcerations of the limb.
14 Still others neither firmly support and secure the catheter tube to the strap nor the strap to the limb and this failure generally 16 results in pain and discomfort to the patient if the tube slips 17 out of position or becomes otherwise relocated. In addition, 18 the prior art devices do not provide a strap of a fixed length 19 which may be varied in size to accommodate limbs or body por-tions of numerous sizes. We have invented a relatively inex-21 pensive fastening device in which ~hese disadvantages are suc-22 cessfully avoided and which is particuLarly useful in providing 23 generally firm but gentle support for catheter tubes and the like.
24 SUMMA~Y OF THE INVENTION
The invention relates to a separable fastening device 28 comprising a flexible strap member adapted to support an elonga-ted member such as a catheter tube and the like to another 28 member such as a leg o~ a patient. The fas~ening device com-29 prises a flexible strap member including a first flexible strap 3 section having on a first surface portion a plurality of en-3 gaging elements upstanding therefrom. The strap member also ll~Z199 1 ¦ includes a second flexible strap section having on a surface por-2 ¦ tion opposite the first surface portion, a pluraLity of mating 3 ¦ eslgaging elements upstanding therefrom. At least one flexible 4 strap section defines an openiny extending therethrough and the ¦ opening is dimensioned and spaced sufficiently rom the other ~3 ¦ strap section so as to reCeiVe a free end portion o one o the 7 strap sections such that at least a portion of one of the strap 8 ¦ sections may be looped about at least a portion of the elongated 9 ¦ mem~er and positioned within the opening with the engaging ele-10 ments o the opposed s~lrfaces positioned in engaged ace-to-face 11 ¦ relation to support the elongated member.
12 ¦ Although the astener strap may be of a unitary con- .
13 ¦ strUction, preferably it is constructed of VELCRo~9 brand separabl~ i 14 ¦ fastener tape materials suitably secured to each other to provide 15 ¦ the desired arrangement. The separable fastener tape may have 1~3 a base member, woVen or kni~ted of a synthetic heat deformable 17 material such as nylon, polyester, and the like, having resilient 18 engaging elemen~s upstanding from the respective base member.
-19 ¦ In the present embodiment, the engaging elements are constructed 20 in the form of hook-type hooking elements which mate with loop-21 ¦ type hooking elements on their opposed engaging surface portions.
22 However, it should be understood that any flexible engaging 23 elements, including mushroom-li3ce elements, resilient projections, etc., which are readily securable in face-to-face relation, and 25 which particularly resist force~; parallel to the interfaciaL
2~ plane of engagement, are contemplated within the scope o~ the 27 present invention, provided the fastener st:rap is flexible. Such 28 mushroom configured hooking elements as the type disclosed in 29 U.S. Patent Nos. 3,138,841 and 3,320,649 both to Naimer, and 30 U.S. Patent Nos. 3,718,725 and 3,770,359 both to Hamano are con-~--1 templated. Furth~r examples o~ knitted form fastener members 2 contemplated within the scope of the present in~ention are dis-3 closed in U.S. Patent Nos. 3,530,687 and 3,539,436 both to Hamano.
4 In the preferred embodiment, the first strap section is comprised of a strip of knitted textile material made from nylon multifilamentary yarns and constructed to have a multiplicity of ~; 7 loop-type filamentary engaging elements upstanding from a surface 8 o the textile material. A polyurethane foam material substrate 9 is secured to the opposite surface of the textile material. The advantages of a strap section having such a foam material sub-11 strate are numerous. For example, when a portion of the foam 12 material is looped about an elongated member such as a catheter tube and positioned in contacting, supporting relation therewith, 14 the foam provides a soft, but firm non-slip support for the cath-eter tube and does not constrict the 10w of 1uids through the 16 tube. Consequently, when the foam material is placed in encom-17 passing relation about the human limb its frictional resistance 18 and stretchability are such as to firmly secure ~he tube to the lg strap and the strap to the limb. The cushioning characteristics of the foam material uniquely prevents the constriction of blood 21 through the encompassed limb while simultaneously providing the 22 necessary support for the tube. Since the porosity of the foam 23 material allows air to circulate therethrough to the limb, it 24 also prevents excoriation of the skin (chafing). The foam mate-X5 riaL textile combination contemplated in the preferred embodiment 2~ is a strap material of approximately 1/4 inch thickness and is 27 marketed by VELCR0 Corporation under the registered trademark 28 VELFOAM.
29 In a further embodiment of the invention, it has been found to be particularly advantageous to provide a relatively 31 short strip of hook-type fastener tape secured to a surface por-32 tlon of ~he foam material near the opening in the first strap 33 member. Thus, when the first strap section is positioned in en-

4 In the preferred embodiment, the first strap section is comprised of a strip of knitted textile material made from nylon multifilamentary yarns and constructed to have a multiplicity of ~; 7 loop-type filamentary engaging elements upstanding from a surface 8 o the textile material. A polyurethane foam material substrate 9 is secured to the opposite surface of the textile material. The advantages of a strap section having such a foam material sub-11 strate are numerous.

29 In a further embodiment of the invention, it has been found to be particularly advantageous to provide a relatively 31 short strip of hook-type fastener tape secured to a surface por-32 tlon of ~he foam material near the opening in the first strap 33 member. Thus, when the first strap section is positioned in en-
-6-B
circling relation with the member such as a body section or limb, the strip of hook-type fastener tape is conveniently positioned to secure itself to the multifilamentary engaging elements of the first strap section while the foam material frictionally grips the member to thereby retain the entire fastener in a taut condition thereabout.
The first strap section is advantageously configured with a tapered end portion generally adjacent the end which is con-nected to the second strap section. In its preferred form, -the second strap section is configured and dimensioned such that positioning at least a portion of the tapered end portion of the first strap section about the catheter tube in contacting relation therewith, provides cushioned support for the tube while a port-ion of the second strap section extends through the opening. The hook-type engaging elements of the portion of the second strap section which extend through the opening, matingly engage the upstanding multifilamentary loop-type engaging elements of the first strap section so as to retain the catheter tube within the cushioned support. It will be seen further that in the pre-ferred embodiment of the invention, the hook fastener tapes, aswell as the opening, are configured and disposed generally away from an end portion of the first strap section. Although the hook and loop-type fastener tapes permit adjustability in the size of the strap, the combination of knitted textile fabric and foam material may be readily severed to permit the creation in-situ of several sizes which may accommodate human limbs of various proportions. Thus, a single length fastener may be provided for virtually all limb sizes, taking into consideration, not only the variations from person to person, but also the variations from one type of limb to another, e.g. the variations from legs to arms, etc.

~0 For the puxpose of the description which follows, the ~ 2~9~
references to fastener tapes having "hook-type hooking elements"
and "loop-type hooking elements" contemplate all such separable fastener tapes of the "press to close, peel to open" type. For example, engagin~ elements of the loop-type may include filamen-tary hooking elements upstanding from a surface of the fastener tape, as well as engaging elements in the form of loops per se upstanding from such tapes. Further, hooking elements of the hook-type, contemplate such engaging elements as mushroom, burrs and the like, as well as hooks per se upstanding from a surface of the fastener tape.
Referring to Fig. 1, there is illustrated a separable fastening device 10 in the form of a strap member comprised of a first strap section 12 having a knitted fastener tape 16 and a plurality of resilient loop-type hooking elements 14 upstanding from one surface of the fastener tape 16. A second strap section 20 has a plurality of mating hook-type hooking elements 18 up-standing from a surface thereof which is positioned opposite to the loop-type hooking surface of tape 16 of the first section 12.
The first and second strap sections may be entirely integrally constructed or connected by sewing, welding, gluing, etc. In the preferred form, they are attached to-each other as shown by pressing the mating surfaces of two respective end portions to-gether. The knitted loop fastener tape 16 is preferably of the type marketed under the trade name "V22-70" and is attached at 21 to a separate length of VELCRO~ brand hook fastener tape 18 such that the loop elements 14 of the knitted tape 16 and the hook elements 18 of the other tape 20 face in opposite dir-ections.
Referring further to the drawings, the VELCRO~ brand hook fastener tape 20 has a woven nylon base and resilient hooking elements 18 upstanding therefrom. The loop fastener tape _g_ lll)Z19!3 1 16 of the other section consists of a Tricot knit nylon tex~ile 2 ¦ material havlng a plurality of multifilamentary nylon yarns 14 3 ¦ upstanding from one surface. The multifilamentary yarns are ¦ interknitted into the base member with floating stitches and the 5 ¦ material is thereafter brushed or napped to ca~se the multifila-¦ mentar~ yarns to stand and appear as a fuzzy, pile surface which7 has been found to conveniently engage the VELCRO0 brand hook
8 ¦ fastener tape in a manner similar to the engagement with VELCRO~
9 ¦ brand woven loop material. While this filamentary brushed sur-
10 ¦ face does not provide the same holding power as VELCRO~ brand
11 ¦ fastener tape ~i.e. having actual loops upstanding from one sur-
12 ¦ face), its relatively inexpensive knitted character has been
13 ¦ ound to provide holding capability which is sufficient for use ir
14 ¦ supporting numerous types of medical devices as will be seen in
15 ¦ the description as it develops.
16 Referring once again to Fig. 1, strap section 12 is
17 ¦ constructed af a layer of polyurethane foam 24 secured by 1ame
18 lamination to the base o~ the VELCRO~ brand V22-70 loop fastening
19 ¦ tape 16. ~he combination of multifilamentary yarn material V22-7~ I
~0 ¦ with the polyurethane foam material is a stretchable foam backed 21 ¦ material known as VELFOAM~ having somewhat elastic properties and 22 is commercially available through the VE~CRO~ brand fastener tape 23 distribution system.
24 The strap section 12 has a tapered end portion 26 and defines an opening 28 extending throu~h the knitted fastener and 26 foam materials and spaced generally adjacent the tapered portion 27 such that the free end o the other strap section 20 may encircle 28 catheter tube 30 and pass through the opening 28 as shown partic-29 ularly in Figs. 2 and 3. The opening 28 is configured and suf-~iciently dimensioned to accept the ree end of the strap section 31 20 as shown. Furthermore, the tapered configuration of the end 3 portlon of strap section 12 facilitates insertion thereof through ~z~
the opening 28 with strap section 20. As will become readily apparent to persons skilled in the art, the opening may be alt-ernately located in the second strap section 20 with the free end of the second strap section passing therethrough.
As further shown in Fig. 1, strap section 12 has secured to its foam side a separate length of VELCRO brand hook fastener tape 32. A third section 32 of fastener tape having hook-type hooking elements upstanding from one surface is positioned gen-erally adjacent the opening 28 as shown and is glued to the foam material. Alternately, other suitable known securing techniques may be utilized such as flame lamination, etc.
As shown in Figs. 2 and 3, catheter tube 30 is positioned adjacent the surface of the foam material 24 of strap section 12 between thé tapered end and the opening 28. A portion of the hook fastening tape of strap section 20 and the foam material 24 of strap section 12 encircles the catheter tube 30 in a firm, but ~; gentle manner. The major portion of the free end of strap sect-ion 20 extends through the opening 28 as shown and is conveni-: ently positioned to be mated with the loop elements of the en-gaging surface of strap section 12 to thereby define an endless loop comprised of the tapered end portion of the strap section 12 - looped upon itself. As strap section 20 is pulled in the direct-ion of arrow A in Fig. 2, the endless loop formed thereby tightens and firmly secures itself around the tube 30 while the endless loop is formed with the foam surface 24 of the strap section 12 in contiguous relation with the tube 30.
Referring now to Fig. 3, the endless loop of strap sec-tion 12 is shown tightly wrapped about the catheter tube 30.
Although the entire strap section 20 is shown extending through the opening 28, this is not necessary. It is sufficient to ex-tend a free end portion of strap 20 through opening 28 to facilitate ~z~
mating engagement of the surfaces of the strap sections. In Fig. 3, a part of the tapered portion 26 of the first strap sec-tion also extends through the opening 28 although this is also not necessary. However, as in the case of the strap 20 the passage through the opening of a substantial portion of the tapered por-tion of strap section 12 is desirable since it enhances the se-curing of the endless loop about the catheter tube 30.
In Fig. 3, the free end portion of the second strap sec-tion 20 is shown releasably attached to a portion of the strap section 12 at location "B". The hook-type elements of the strap section 20 are pressed into face-to-face relation with the mating engaging loop-type elements of the strap section 12. By releas-ably attaching together the mating engaging elements of these two strap sections, a second generally endless loop is created which secures and encompasses the leg as shown in Fig. 4.
The foam material acts as a soft, but firm support having a friction surface which comfortably encompasses the limb and thereby prevents the tube from slipping out of its respective endless loop. Since the foam surface is porous and breathable, the chances of producing ulcerations on an encircled human limb are minimized. The foam material also prevents the skin from chafing since it is breathable and resilient and it allows air to circulate to the skin, yet has sufficient frictional resistance and stretchability so as to firmly secure itself about the human limb. Furthermore, the cushioning property of the foam material prevents the constriction of the blood circulating through an en-compassed limb, as well as preventing the crushing of an encircled catheter tube. In addition, the combination of the variable and precise fastening capabilities of the VELCRO~ brand fastener tapes with the cushioning characteristics of the foam 1~2198 l¦ material prevents con~triction of blood flow through an encom-2 ¦ passed leg or arm.
' Referring once again to Figs. 1 and 3, it can be seen 4 ¦ that the free end portion "C" of strap section 12 may be easily 5 ¦ cut with a pair of scissors to reduce the size of the fastener.
¦ Advantageously, the various VELCRO~ brand hook fastener tapes, 7 ¦ as well as opening 28 are disposed generally away from the free ¦ end portion 22 o the strap section 12 and these features facil-9 ¦ itate the cutting of strap section 12 to accommodate the broad 10 ¦ range of human limb sizes from patient to patient and from arm 11 ¦ sizes to leg sizes.
12 ¦ Referring to Fig. 4, the fastening device of Figs. 1 13 ¦ through 3 is secured to the right thigh o a patient and adapted 14 ¦ to support a catheter tube 30. The catheter tube 30 is sho~n 15 ¦ secured and supported by the endless loop previously described.
16 ¦ A second endless loop encircles the thigh as shown, and the strap 17 ¦ section 20 is releasably attached to the strap section 12. The 18 ¦ unique configuration of the present invention thereby prevents l9 the catheter tube from riding up, down, or sliding across the patient's thigh. Thus, the painful movement of an unsecured 21 catheter tube is easily and economically eliminated by the pre-22 sent invention. In addition, it has been found that the gentle 23 and firm support provided for the catheter tube is such that it 2~ is capable of maintaining,the tube in traction where this may be required.
26 Although the present fastener device is preferably 2r adapted to support catheter tubes of various types, it should be 28 understood that the unique arrangement is adaptable for supportin 29 any object to a structural member without departing from the scope of the invention. For example, in Fig. 5, the tapered end 31 portion of strap section 12 is encircled about a rod or bar 34 32 ~ to support the rod in a manner similar to the support of the ~ -` 1113Zl9~ ;
l ¦ catheter tube 30. The other end portion of strap section 12 is 21 looped about the structural beam 36 to form an endless loop ~ thereabout, and the loop fastener surface of strap section 12 is 4 ¦ secured to the hook fastener tape 32.
5 ¦ Accordingly, it is significant to note that numerous ¦ other astener applications will immediately be foreseen by r ¦ those skilled in the art. For e~ample, the present fastener is 8 ¦ suitable for use in EKG s~raps, I~Vo tube straps, wrist and ankle ¦ restraints, arm slings, anesthetic gas delivery hose straps, con-lO ¦ duit or cable supports, flower pot hangers, utensil or pencil ll ¦ holders for handicapped persons, structural devices, etc. While 12 ¦ other types of straps may be used for the above application, it 13 ¦ has been found that the unique configuration o the present in-14 ¦ vention makes it possible to firmly secure and support delicate 15 ¦ members relatively inexpensively and avoid any real or potential 16 ¦ problems of crushing these members. Furthermore, as can be seen 17 ¦ from the foregoing, the supporting and securing is accomplished 18 ¦ in an improved manner notwithstanding the fact that the members lg ¦ to be secured have irregular, nonconforming configurations.
~0 ¦ with the polyurethane foam material is a stretchable foam backed 21 ¦ material known as VELFOAM~ having somewhat elastic properties and 22 is commercially available through the VE~CRO~ brand fastener tape 23 distribution system.
