Definitions
- blood banking services such as the American Red Cross among others, obtain, process, and store whole blood and blood components for a variety of medical uses such as transfusions and the like.
- all collected blood is analyzed to characterize its immune properties or so-called "blood type”.
- all blood must also be pre-tested for the presence of communicable disease pathogens, such as the hepatitis virus and the human immunodeficiency virus (HIV).
- communicable disease pathogens such as the hepatitis virus and the human immunodeficiency virus (HIV).
- HIV is the causative agent of the uniformly fatal AIDS disease in humans, and thereby mandates the safest possible environment when handling human blood.
- Blood collection as now commonly practiced utilizes a system including (1) a straight metal needle whose pointed end is inserted into a human donor to access a blood vessel wherein the needle usually includes a gripping portion bonded thereto to facilitate manual manipulation; (2) a length of flexible tubing in fluid communication at one end with the non-pointed proximal end of the needle; and, (3) one or more blood storage bags connected to the other end of the tubing.
- helpful agents such as citrate-phosphate dextrose (CPD) are commonly included as anti-clotting additives within the collection system to prevent coagulation of the blood and permit it to remain in fluid condition.
- CPD citrate-phosphate dextrose
- the medical or health care worker initially shuts off tubing flow as by a clamp, and then grips the needle with one hand by the enlarged grasping component thereof, removing the needle from the donor. Thereafter, the exposed needle tip, which is now blood-contaminated, is inserted through a rubber stopper or seal into a sample collection test tube, and the clamp is released to permit drawing of a sample of the collected blood reversely through the needle and into the test tube usually held in the other hand.
- the physical movement of the contaminated needle with one hand toward and in close proximity to the other hand holding the sample collector there is a significant probability of self-inflicted injury.
- the needle point may misalign with the rubber seal and puncture the worker's hand.
- the frictional resistance of the rubber stopper retarding needle withdrawal suddenly ceases as the needle pulls dear, and there is an involuntary tendency and reflex for the worker's hand holding the needle to recoil back toward the hand holding the test tube.
- the present invention embraces improved and reliable needle-carrying and manipulating elements, and modes of fabrication and assembly thereof.
- the present invention addresses this problem confronting the healthcare industry and is designed specifically to eliminate needlestick injuries of the type described in connection with blood collection.
- a new and improved system which (1) shields the blood-contaminated needle simultaneously with its withdrawal from the donor, and (2) uses a separate shielded needle in a blood sample tube holder for the safe drawing of blood samples, whereby the probability of an exposed contaminated point being in any injury-causing proximity to a medical worker is virtually nil, whereby the threat to or even the fear of HIV or other disease by the worker is eliminated.
- a unique and mechanically simple but reliable snap-on needle enclosing guard is provided on a specialized needle device disclosed herein, which is similar in some respects to the needle safety device as set forth in our aforenoted application Ser. No. 07/610,583 now U.S. Pat. No. 5,176,655.
- the needle upon withdrawal of the needle from the blood donor, the needle is immediately retracted within the guard and a shield positively blocks the contaminated needle point and access thereto.
- Two different forms of the needle assembly are provided and which have differing fabrication and use advantages.
- FIG. 1 is a diagrammatic illustration of prior art presently practiced blood collection technique and equipment
- FIG. 2 is an illustration of prior art sample collection in a test tube
- FIG. 3 is an overall perspective view of the blood collection system of the invention.

- FIG. 9B is a view taken on the line C--C of FIG. 9A;
- FIG. 9C is a section view similar to FIG. 9B but with the shield and needle removed;
- FIG. 10A is a view similar to FIG. 6B but showing a modified form of gripping portion for the needle.
- FIG. 10B is a side view of the modified gripping member, internal portions being shown in phantom;
- FIG. 10C is a parital assembly view of a needle and its securing disc with the modified gripping member
- FIG. 10D is an assembled view of the parts of FIG. 10C.
- FIG. 10E are front and side views of the needle securing disc.
- FIGS. 1 and 2 there is generally indicated in FIGS. 1 and 2 a typical widely used blood collection and blood banking system which in use presents the aforementioned safety and needlestick hazards.
- a hollow metal cannula needle 10 having a tapered point 12 has a finger-grippable enlarged annulus 14 secured to a proximal needle portion to facilitate handling and maneuvering of the needle in the collection and sampling process.
- the donor's skin is punctured by the point 12 and the same is the positioned in a blood vessel.
- the proximal end 16 of the needle is bonded, clamped, or otherwise secured in known manner to flexible tubing 18, the opposite end of which communicates with a blood collection bag 20, whereby the needle, tubing, and bag form a closed passageway for the flow of blood.
- Clamp means 22 of known form is provided along tubing 18 to regulate or shut off blood flow as may be required from time to time during collection or thereafter.
- a standard blood specimen tube 24 having a usual rubber seal stopper 26.
- Such sealed tubes are conventionally provided on manufacture with a partial vacuum in its internal chamber 28 to facilitate the drawing of blood thereinto.
- Such specimen tubes 24 are routinely used for taking small volume blood samples for analysis from donor blood obtained for blood bank processing and storage purposes.
- the current practice of obtaining the blood samples entails a procedure which is in fact hazardous to health care workers.
- clamp 22 is used to shut off flow.
- the fingers 30 of one hand of the worker grasp enlarged collar 14 and remove needle 10 from the donor and move the now-contaminated needle point 12 through space to aim and position the point 12 to puncture stopper seal 26 of the specimen tube 24, the latter being held by fingers 32 of the other hand of the worker, as seen in FIG. 2.
- the clamp 22 is released, and a small quantity of blood is drawn in reverse flow from the tubing 18 into the partially evacuated chamber 28 in specimen tube 24.
- the contaminated needle tip 12 Apart from other real possibilities of mishandling the contaminated needle tip 12 during donor withdrawal and holding the same openly as the specimen tube is manually positioned, it is principally the manipulation of needle 10 for alignment and entry into specimen test tube 24 that constitutes a significant danger of accidental needlestick injury to the health care worker.
- the danger of self-inflicted injury increases substantially.
- the needle point 12 may miss the small-diameter stopper entirely and puncture the fingers 32.
- the needle point may be improperly positioned at an angle, on the stopper 26 and with stopper-puncturing force applied the needle may slip laterally from the stopper and puncture the worker's hand.
- the blood-contaminated needle is shielded simultaneously with its withdrawal from the donor whereby no inadvertent puncture can occur, and a separate shielded needle in a blood sample tube holder is used for safe drawing of the blood sample.
- needle cannula 40 somewhat similarly to needle 10 in FIG. 1, includes the usual needle point 42 and further includes a special gripping portion or base member 44 bonded therearound near the needle proximal end 46, which latter is secured in usual manner to the flexible blood collection tubing 48 having its internal flow passage 50.
- Tubing 48 terminates into one branch end 51 of a Y-connector 52 of well-known form, while a length of tubing 54 extends from the other end 56 of the Y-fitting 52 to communicate with blood bag 58.
- Well-known flow control adjustable clamps 70, 70 are provided along the length of tubing 48 and 54.
- the Y-fitting includes a second branch 60 providing a sampling port 62 communicating with the tubing 48.
- the port 62 is a conventional medical industry fitting, commonly known as a Luer female fitting.
- the port 62 is adapted to cooperate with a standard blood collection tube holder 64 having a standard multiple sample blood collection needle 68 with a rubber sleeve 72 associated with a male Luer fitting 74, which latter forms a dripless collection with female port 62.
- the fitting 74 Prior to sample collection into tube holder 64, the fitting 74 is inserted into the port 62 to prevent drippage until the collection tube is inserted into holder 64 in known manner to open access to needle 68.
- the safety and guard assembly 80 in FIGS. 3 and 4 carrying needle 40 in overall respects is in accordance with that disclosed and claimed in U.S. Pat. No. 5,176,655.
- the same includes a needle shielding or guide body 82 having an opening shown as a bore extending from port means in its front surface or distal end 84 to proximal end 86 within which needle 40 is slidably received.
- the body 82 is shown for illustrative purposes as being of square or rectangular cross-section, the particular configuration may vary within the limits of the required structure and function thereof.
- the assembly may readily be fabricated as by molding from plastic, such as polyethylene, polyvinyl chloride, or the like.
- the rear portion of front guide 82 may be provided with laterally extending flexible winglike members 88, and flexible restraints or tethers 90 extending from wings 88 interconnect the guide 82 and the base section 44 which is bonded to needle 40. In the absence of wings 88, the tethers 90 may be connected directly to the body 82.
- the wings 88 also include respective upstanding lugs 102, 102 outwardly from the guide body 82 for cooperation in use with an upstanding lug 104 on base section 44, as described further hereinafter.
- needle guide body 82 is provided on either side thereof with a series of laterally extending projections or lug members 92 and 94 for cooperative abutment with gripping legs 96 of a specially configured leaf spring 100.
- the spring legs 96 could cooperate with other forms of abutments than flange-like projections, as recesses in the guide body 82, for example.
- the spring 100 forms an essential element of the safety needle assembly.
- the spring includes an inturned imperforate blocking flange 98 at its forward end, which rests upon and is biased transversely against needle 40 when the needle is extended for use as shown.
- the needle 40 is so positioned relative to the imperforate flange 98 that the flange 98 bears against the needle on the side area thereof corresponding to the maximum length of the needle at the pointed tip 42 of the conventionally tapered or bevelled needle.
- the proximal end 101 of spring 100 is also angled and stressed against the guide body 82, the spring being maintained in position by the inwardly angled portions 97 of legs 96 bearing against projections 94.
- the one-piece spring 100 facilitates assembly of the unit, as the gripping legs 97 thereof readily snap past the body projections 94, and positively hold the spring on the body with no chance or accidental removal.
- the assembly is thus a one-step process minimizing cost with no sacrifice of safety or reliability.
- the projections 94 may be replaced by molded indentations in the body 82 with equally effective results.
- the forward or vertical projections 92 preclude any likelihood that the spring could slide forwardly on the body to expose excessively the needle, while the safety flange obviously precludes rearward movement of the spring.
- the needle assembly 80 comprises the needle 40, the body 82 slidably crying the needle, the flexible tethers 90, the rearmost base section 44 bonded to the needle, and the spring 100.
- the assembly 80 is as shown in FIG. 4 with the wings 88 initially flexed sufficiently downwardly to permit base section 44 to closely approach or abut the forward needle guide body 82 from the former position of FIG. 3. Thereupon, the wings 88 are flexed upwardly and gripped as seen in FIG. 5. In so doing, the wing lugs 102 are repositioned to be disposed immediately rearwardly of the base member lug 104 as best seen in FIG. 5a. Thereupon, with forward movement by the fingers gripping wings 88, base member will move forwardly therewith to insert the needle point into the donor.
- the medical technician may leave the wings down and separately manipulate the base member 44 and the needle carried thereby to insert the needle without concomitant interlocked or interengaged lugs 102, 104.
- the spring relaxes and snaps the angled face 98 thereof transversely of the guide body forward face 84 and securely encloses the needlepoint within guide body 82 as seen in FIG. 6D.
- the actual device of the invention is quite small and the needlepoint is absolutely without capability of exposure and contact with medical or donor personnel once retracted and blocked, whereby needlestick injury is positively prevented in a simple and effective manner.
- FIGS. 9A-C A modified body 110 for receiving the needle is shown in FIGS. 9A-C in lieu of the body 82.
- the same is not provided with a tubular bore as in FIG. 3, but with an open-sided U- or V-configuration, as well seen in FIG. 9B.
- the spring 100 has a modified rear tang 101a dimensioned to fit within the body 110 and bear against the needle 40 therein.
- the needle is held firmly in the body, and upon snap operation of shield 98 as heretofore, the needle is made safe being blocked at its proximal end, gripped at 101a, and overlaid by the body generally of the spring, whereby access cannot be had to the needle point.
- the elements of the assembly 80 are essentially the same. It will be evident that the U-shaped body facilitates ready assembly of the needle system.
- FIGS. 10A-10E illustrate a modified form of gripping member and a simplified assembly technique for associating the needle 40 therewith.
- the modified gripping element 120 is similar to that at 44 in FIG. 3 in being of polymeric material and generally of cylindrical or polygonal external configuration and includes a similar upstanding wing-engaging flange 104.
- a short needle-diameter bore portion 122 is provided in the distal end thereof, the member 120 being countersunk therebehind to an enlarged diameter chamber 124 having an internal front wall 126.
- needle-gripping and securing disc 128 having a diameter substantially that of chamber 124, and having a hole or aperture 129 therethrough bounded by short radial cuts 130.
- Hole 129 is of a diameter slightly less than that of the needle 40 whereby the cuts 130 permit slight flexing of the disc as the needle is inserted therethrough in a snug mechanical interference fit
- disc 128, which is preferably fabricated from thin flexible metal, is provided at its periphery with a plurality of rearwardly directed barbs or tangs 132. Accordingly, the disc is assembled with gripping member 120 by axially advancing the disc into chamber 124 against front wall 126, and is locked therein by the presence of the barbs 132 whereby the disc cannot be removed and the needle is securely positioned. Further, a liquid bonding agent is applied about the needle at 134 (FIG. 10D) at its exit from member 120, thereby sealing the needle to the base gripping member 120.
- the needle is reliably secured to the member 120 both by the mechanical-interaction of the disc 128 with base 120 and also by the bonding material 134.
- the body 82, gripping portion 44, tethers 90 and wings 88 if used may be simultaneously molded, as by injection molding, of polymeric material, as polyvinyl chloride.
- the unit assembly may then have the needle 40 appropriately positioned in the body 82 and the gripping portion 44 for bonding of the distal needle portion to member 44.
- the needle need not necessarily be propositioned therein, but all elements other than member 44 can be flexed to one side while the needle is fixed to 44. In either case, thereafter the spring 100 is snap-fitted onto the body, and the assembly is complete and ready to use.
- the same advantages in assembly accrue with the needle securement technique of FIGS. 10 A-D, as above discussed.
