Abstract
A needle-stick safety syringe includes an inner tubular body, plunger, and needle extending from a distal end of said inner tubular body, an outer tubular housing concentrically and slidingly surrounding at least a portion of the inner tubular body and biased apart from the inner tubular body. A recess is defined within an interior wall surface of the outer tubular housing, and a latch attached to a distal end of the inner tubular body. The latch includes a ring-shaped collar attached to the distal end of the inner tubular body and includes a cantilevered push-stop. A portion of the cantilevered push-stop is sized to fit within the recess when the latch is sufficiently disposed within the outer tubular housing.
Description
- Priority is claimed from applicant's co-pending U.S. patent application Ser. No. 09/525,144, filed Mar. 10, 2000 entitled “Safe Needle Device for Syringe”, now U.S. Pat. No. 6,322,540 (2001).
- The present invention relates generally to sharp medical instruments such as syringes and needles, and more particularly to protecting users of such instruments from inadvertent injury from the instruments.
- Adequately protecting physicians, nurses, and other medical staff users of sharp medical instruments has always presented a challenge. More recently, with the spread of AIDS, hepatitis, and other highly infectious diseases, it has become even more important to protect users of syringes, scalpels, and other sharp devices from injury and infections, especially in a health care facility. The Needle Stick Safety and Prevention Act passed unanimously in both houses in 2000, and thirty-five states have enacted legislation mandating protection to medical staff at such facilities from wounds or other injury resulting from use of such instruments. See for example State of California Labor Code §144.7(d).
- Various protective devices have been attempted in the prior art, but generally such devices have not functioned well, were not user-friendly, and generally have not been widely accepted, notwithstanding a need for such devices.
- Many prior art devices overlook the fact that when a medical practitioner uses such a device, a syringe for example, at best one hand is available to hold the device. For example, a nurse preparing a patient for an injection with a syringe requires one hand to clean the patient area to be injected, and one hand to hold the syringe while injecting the needle and syringe contents into the patient's tissue. Upon injecting the syringe contents, the nurse will withdraw the needle from the patient with one hand, and typically will press a compress against the injection site with the other hand, to halt any flow of blood.
- In typical prior art protective devices, the nurse or other medical practitioner must now use the free hand to twist a cover over the syringe or sharp portion of other medical device. Thus, one hand is required to hold the device while the other hand twists the protective prior art cover. In the interim, the needle portion of the device may drip blood onto the patient or the nurse, with resultant contamination. Further, unless great care is exercised while maneuvering the syringe to utilize the protective prior art cover, the skin of the medical practitioner may inadvertently be punctured, again with potentially serial adverse medical consequences.
- An exemplary prior art protective device is disclosed in U.S. Pat. No. 5,885,257 to Badger (1999), a somewhat cumbersome device in which a compressed spring retracts a needle syringe into a holdable barrel after use, and wherein a second hand appears required to actuate the spring release mechanism. Unfortunately, during an injection when Badger's spring is compressed, the needle may not extend sufficiently clear of the device to attain a proper injection depth. Further, Badger disclosed a notched plunger intended to be broken after use, to prevent reuse of the syringe. But if the plunger is not broken, the syringe is free to be reused, in violation of good medical practice and federal law. Further, the spring may urge the notched plunger so far rearward to allow blood or other fluid to escape from the rear end of the barrel.
- Thus, there is a need for a protective device for a syringe or similar medical instrument that protects the instrument while allowing the instrument to be used with one hand. Such device should further prevent the instrument from being used after an initial use, and should adequately protect users from puncturing or otherwise wounding themselves with he instrument after it has been used. Finally, such device should prevent users against contamination from fluids within or in contact with the instrument.
- The present invention provides such a device.
- Applicant's parent application disclosed a one-time useable needle-stick safety syringe that could be used with one hand. The syringe included an inner tubular body (body) with an extended needle at one end, and a plunger mechanism at the other end. A larger diameter protective outer tubular housing (housing) concentrically surrounded at least a portion of the body, and included a washer-like plug at the syringe plunger end and a washer-like collar with a cantilevered push-stop at the syringe needle end. The body was free to slide axially within the housing. A spring surrounded the plunger near the syringe plunger end to urge the housing toward the syringe needle end. Before use, the push-stop prevented the spring from urging the housing over the syringe needle end. After use, the person using the syringe would press the push-stop with a finger of the hand hold the syringe. This action allowed the housing to be urged by the spring over the syringe needle end. A slot in the housing near the syringe piston end then captured the push-stop, thus preventing reuse of the syringe, since the needle region was now surrounded by the housing. In this configuration, the syringe was safe in that the needle was protected; a person would literally have to insert a finger into the housing before contacting the needle.
- The present invention advantageously further prevents an attempt to reuse the syringe by replacing the slot in the housing with a recess in the inner housing surface. Preferably the recess defines an annular shape such that regardless of any twisting between the push-stop and the syringe housing, the recess will always engage a portion of the push-stop when the housing surrounds the push-stop. After one use of the present invention, as the housing is urged toward the syringe needle end, the recess traps the push-stop completely within the housing, to prevent reuse. With this configuration, one cannot readily release the push-stop, even in a very deliberate attempt to reuse the syringe. Preferably the present invention now includes a second outer trigger that actuates the push-stop to promote more consistent and ready retraction. In addition, the present invention preferably disposes the compression spring within, rather than without, the syringe. Finally, the ridge and groove feature of the parent invention may be dispensed with to minimize friction when using the present invention.
- Other features and advantages of the invention will appear from the following description in which the preferred embodiments have been set forth in detail, in conjunction with the accompanying drawings.

- FIG. 7 is a cross-sectional view is the syringe shown in FIG. 5, but in a released disposition in which the needle is protected by an outer tubular body that cannot readily be released for reuse of the syringe, according to the present invention; and
- FIG. 8 is a perspective view showing use of the syringe of FIGS.5-7 in use by a medical practitioner.
- To provide a better understanding of the present invention, the invention of applicant's parent invention, now U.S. Pat. No. 6,322,540 (2001) will first be described with reference to FIGS.1-4.
- FIG. 1 depicts a typical commercial syringe of the so-called “TB” type, that is a syringe with a 3 cc capacity. The syringe shown operates in a standard fashion, and includes a
plunger 1 that slides within an innertubular body 15. Innertubular body 15 includes aflange 2 at its proximal end, an extendedneedle 9 at itsdistal end 8, and further includes aprotective cover 13. - In accordance with applicant's parent invention, a
collar 11 is provided atdistal end 8, the collar being permanently or frictionally fitted or affixed onto the distal end oftube 15. Collar 11 includes a flexiblecantilevered stop 12 that has a button-type termination 5 that is easily engageable by ahuman hand 20, as shown in FIG. 4. - As shown in FIG. 1, the syringe further includes a protective sleeve type
tubular body 7 that includes aplug 3 at its distal end.Tubular body 7 has a larger diameter thaninner syringe body 15, and can slide concentrically over the syringe body.Syringe body 15 is freely slidable withinplug 3. - A
coil spring 6 is initially slid on the innertubular body 15 and abuts against theflange 2 at one spring end, with the other spring end being retained byabutment unit 3. In this unreleased state, cantilevered stop 12 retainsspring 6 in a compressed condition withbutton 5 becausecantilevered stop 12 hooks against the proximal edge of thetube 7. - In actual construction,
spring 6 would be slid onto the syringe tube. Thereafter theplug 3 is slid againstspring 6, and outerprotective sleeve 7 is slid on, compressingspring 6 and mating withplug 3. Finally,collar 11 is permanently affixed, for example, by friction fitting or even glueing. - FIG. 3 depicts further details of applicant's parent invention, and depicts
spring 6 andabutment 3, where outer protectivetubular body 7 includes aninterior groove 10. When it is depressed by a human finger, stop 12 is guided bygroove 10 toslot 4 in the proximal end oftubular body 7. To further prevent twisting and enhance the travel of thecollar 11, the collar includes a pair of diametricallyopposed grooves axial guides tubular body 7. As described above, the outer diameter ofcollar 11 is freely slidable withintubular body 7, however its inner diameter is frictionally fitted or permanently affixed to the inner tubular body ofsyringe 15. - After a patient has been injected with the syringe,
needle 9 is withdrawn as shown in FIG. 4, and held in onehand 20 by the nurse or other medical practitioner. The other hand, of course, can be used to press the area of injection. Then with a suitable finger such as theindex finger 20 a,button 5 oncantilever 12 is pressed. As shown in FIG. 2, this action releases tubel5 and allows the force ofspring 6 to relatively move the outer protective tubular body to coverneedle 9. As this occurs inchannel 10,button 5 and itscantilevered end 12 move and are captured byslot 4. - As apparent from FIG. 2, this process is not readily reversible. There is no simple way to effectively depress
button 5 to again exposeneedle 9, e.g., to attempt to reuse the syringe. Thus, the embodiment shown enhances safety of the administering medical practitioner, who can now dispose of the syringe.Protective cover 10 may be fabricated from a transparent material such as plastic or glass to enable viewing the syringe contents and the gradations, as shown in FIG. 1. - Thus, applicant's parent invention provided an improved
needle stick safety 20 syringe that could be used with one hand. The syringe could be easily handled by unskilled persons, without special tools or skills or instructions. Further, outer protective body orsleeve 10 was constructed to preclude rotation or twisting in a retraction mode. As a result, a more linear alignment was achieved, as was straight retrieval of the needle into the sleeve, directly into the locking slot. - Turning now to FIG. 5, an embodiment of applicant's present invention is depicted. Comparing the present invention shown FIG. 5 with applicant's parent invention shown in FIG. 3, several changes are apparent. In the present invention a
recess 18 is formed in the inner wall ofhousing 7 and is sized to engage and trap theupper surface 19 of a somewhat modified cantilever button or push-stop 21. To ensure thatrecess 18 will always trap a portion ofsurface 19 of push-stop 21, it is preferred that the recess be formed as an annulus within the housing interior wall. Thus, regardless of any rotation or twisting between the push-stop and the syringe housing, trapping action can still occur. - Preferably an
external trigger 23 is mounted atend 25 to the exterior distal surface ofhousing 7. Further, theabutment 3 structure shown in FIGS. 1 and 2 regarding applicant's parent invention is preferably now awasher 33, and the length ofbarrel housing 7 is extended to enclosespring 6, as best seen in FIGS. 6 and 7. - As noted, the present invention optionally includes an
exterior trigger 23 that is preferably fabricated from a resilient or at least slightly resilient inexpensive material, e.g., plastic, rubber, etc. and can operate in cantilever fashion. The cooperative action between interior push-top 21, exterior trigger 23 (if present) andinterior recess 19 may further be appreciated from FIGS. 6-9. FIG. 6 shows the syringe, for example, just after use in injecting a patient. - As shown in FIG. 8, as a user-practitioner presses down on the distal end of
exterior trigger 23, e.g., with a forefinger of the hand holding the syringe, at least the distal portion of the exterior trigger is displaced downward to press against a portion ofupper surface 19 of inner push-stop 21. Once the distal end of push-stop 21 is urged downward, e.g., by finger force uponexterior trigger 23,housing 7 is urged byspring 6 to move overcollar 11 and in the direction of the needle (not shown, but to the left in FIGS. 5-8). Ashousing 7 moves to the left (in the orientation shown),recess 18 on the inner surface ofhousing 7 will trapupper portion 19 of interior push-top 21, as shown in FIG. 7. As noted, sincerecess 18 preferably defines an annulus, e.g., the recess is defined as a 360° groove in the inner wall ofhousing 7, trapping can always occur regardless of twisting or rotation of the push-stop. - Once such trapping occurs, one cannot readily free push-
stop surface 19 fromrecess 18, which is to say, a user cannot readily re-use a syringe according to the present invention as the needle portion will remain surrounded by the distal portion ofhousing 7. By contrast, in applicant's parent invention a determined individual might force a narrow tool intowindow slot 4 that was formed throughhousing body 7 to try to depress cantileveredstop 5 downward, to free it from the throughslot 4. If such effort was successful,housing 7 might then be slid away from the needle to (wrongfully) permit the syringe to be reused. But in the present invention,recess 18 is not accessible from outside ofhousing 7, e.g., it is merely a recess in the inner wall of the housing, and is not a through window slot as in the parent invention. - It will be appreciated that
exterior trigger 23 could be dispensed with, if desired, and interior push-top 21 deflected downward by direct contact with an object, e.g., a user-practitioner's finger, to causehousing 7 to surround needle 9 (as shown in FIG. 7). However use of a so-called compound trigger comprising an inner push-top 21 and anexternal trigger 23 to promote a more consistent and easy retraction operation. - Note too from FIGS. 5 and 8 that
axial guide ridges corresponding grooves bias spring 6 preferably is disposed withinbarrel housing 7, rather than external to the housing as was shown in FIGS. 1 and 2 for applicant's parent invention. Preferably the length ofbarrel housing 7 is extended somewhat over that used in the parent invention, to ensure adequate coverage ofspring 6 andneedle 9 before and after retraction, respectively. - Modifications and variations may be made to the disclosed embodiments without departing from the subject and spirit of the invention as defined by the following claims.
