- FIG. 7 is a sectional view showing an embodiment of a retractable syringe after retraction of a retractable needle.
- an embodiment of syringe 10 comprises barrel 1 1 and plunger 20 which is slidably, axially moveable within barrel 1 1, plunger 20 having plunger member 50 and plunger housing 21.
- Replaceable needle assembly 30 comprises retractable needle 39 that comprises cannula 31 and needle body 32 comprising plunger-engaging foot 33, needle mount 36 having screw threaded portion 370 and needle retainer 35. Seal 80 is mounted to projection 52 of plunger member 50.
- Barrel 1 1 comprises plunger end 12 at which is located; collar 13 comprising release ring 14 having rim 141.
- Barrel 1 1 also comprises needle end 15 having mounting member 16 onto which can be mounted replaceable needle assembly 30.
- Mounting member 16 comprises screw thread 17 and is typically glued or otherwise firmly affixed inside needle end 15 of barrel 1 1. Needle seal 40 is also mounted inside needle end 15 of barrel 1 1 behind mounting member 16 (i.e proximal to the user). Sealing base 41 of needle seal 40 seals against inside wall 18 of barrel while body 42 is coupled to mounting member 16.
- plunger 20 comprises plunger housing 21 with skirt 22 having flange 23 comprising inner circumferential ledge 24.
- Skirt 22 also comprises step 27 at an end of skirt 22 proximal to a user.
- Plunger housing 21 further comprises arm 28 having shoulder 29.
- Control rod 60 is releasably connected to plunger member 50 by way of frangible connection 61.
- Control rod further comprises shaft 62, button 63 which is operable by a user and trigger 64 which comprises notch 65.
- the biasing means is spring 70.
- trigger 64 of control rod 60 engages flange 23 of plunger housing 21 by way of notch 65 releasably engaging inner circumferential ledge 24.
- Plunger member 50 further comprises projection 52, which in this embodiment is screw threaded, which is coupled to plunger seal 80.
- Plunger seal 80 comprises inner member 81 and outer member 82 that are releasably coupled.
- Stop 85 is formed between shoulder 86 of inner member 81 and ledge 87 of outer member 82 to minimize or prevent unwanted forward travel of inner member 81 relative to outer member 82 (i.e towards needle end 15 of barrel 1 1), particularly when plunger 20 is initially inserted into barrel 10. Stop 85 selectively allows axial movement of inner member 81 relative to outer member 82 towards the user during retraction, as will be described in more detail hereinafter.
- Inner member 81 further comprises complementary mating portion 83 for receiving and engaging foot 33 of needle body 32 and plunger-engaging recess 84 that is screw-threadedly mounted to projection 52 of plunger member 50.
- Outer member 82 seals against inside wall 18 of barrel to prevent fluid leaking from fluid space 19. It is also noted that inner member 81 and outer member 82 provide a fluid-tight seal at internal interface 88.
- complementary annular ribs and grooves could be added to inner member 81 and outer member 82, or vice versa, to facilitate the fluid-tight seal.
- replaceable needle assembly 30 comprises retractable needle 39 comprising cannula 31, needle body 32 that comprises plunger-engaging foot 33 and shoulders 34A, 34B, needle retainer 35 and needle mount 36 having screw threaded "male" portion 370.
- Needle retainer 35 also comprises fingers 37A, B that respectively bear against shoulders 34A, 34B of needle body 32 which retain retractable needle 39 in needle assembly 30 and prevent inadvertent retraction of retractable needle 39.
- This retaining function can withstand up to a 6N force, but nevertheless allow spring-driven retraction of retractable needle 39, as will be described in more detail hereinafter.
- An advantage of this arrangement is that no other structure ⁇ e.g.
- an ejector member is required to release retractable needle 39 from fingers 37A, 37B.
- Complementary angled faces 38A, B, C and. D also assist preventing inadvertent ejection of retractable needle, if for example subjected to a "needle pull" force 39 from needle assembly 30.
- syringe 10 is typically provided prefilled with fluid contents, such as a vaccine, although without limitation thereto.
- fluid contents such as a vaccine
- plug 90 comprising screw-threaded portion 91 has been fitted into complementary screw-thread 17 of mounting member 16 at needle end 15 of barrel 1 1 to thereby seal barrel 1 1.
- Plug 90 is then unscrewed as indicated by the arrow and removed by the user so that replaceable needle assembly 30 can be mounted by way of screw thread 35 in needle mount 36 engaging complementary screw thread 17 in mounting member 16.
- Replaceable needle assembly 30 may be provided with a removable cover (not shown) for cannula 31 and also a screw- threaded cover (not shown) mountable to screw thread 35 of needle mount 36.
- syringe 10 is ready for use. It will be appreciated that the replaceable needle assembly 30 allows a user to replace a needle that becomes bent or burred. Furthermore, a user may select an appropriate size or gauge needle for delivery.
- plunger 20 is moved axially in the direction of the solid arrow toward needle end 15 of barrel 1 1 to deliver fluid contents of syringe 10.
- complementary mating portion 83 of seal inner 81 receives and snap-lock engages foot 33 of needle body 32. This effectively couples retractable needle 39 to plunger member 50, as shown in FIG. 5. It will also be appreciated that while this embodiment describes male-female engagement between foot 33 and complementary mating portion 83, the reverse arrangement is also contemplated.
- plunger member 50 Retraction of plunger member 50 occurs with sufficient force to dislodge needle body 32 from fingers 37A, B of needle retainer 35.
- inner member 81 of plunger seal 80 uncouples from outer member 82, moving axially towards the user so that cannula 31 and needle body 32, which is coupled to inner sealing member 81 mounted to plunger member 50, retracts in the direction of the arrow in FIG. 6 (inside plunger' housing 21 which remains stationary relative to barrel 1 1).
- control rod 60 retracts, the rate of which retraction is controlled by a user relaxing pressure (such as by way of thumb pressure) against control button 63. As shown in FIG. 7, retraction is complete when base 51 of first plunger member 50 abuts step 27 in plunger housing 21 which is stationary during retraction of plunger member 50 and control rod 60. Needle seal 40, needle mount 36 and needle retainer 35 also remain stationary at needle end 15 of barrel 1 1.
- lock 90 is formed between lock elements in the form of shoulder 29 of arm 28 of plunger housing 21 locked onto rim 141 inside release ring 14 of collar 13 at plunger end 12 of barrel 1 1, to thereby prevent withdrawal of plunger housing 21 from barrel 1 1.
- This also facilitates ease of removal of control rod 60, which can be manually removed from syringe 10 by breaking control rod 60 away from plunger member 50 at frangible connection 61. Control rod 60 may then be discarded as "clean" waste, leaving syringe 10 with plunger housing 21 and plunger member 50 remaining inside barrel 1 1 for a more compact medical waste disposal.
- the present invention provides a relatively simple, robust and inexpensive syringe that is automatically disabled with little or no assistance from the user to thereby prevent, or at least minimize the likelihood of, re-use of the syringe or needle-stick injury to the user.
- the replaceable needle assembly allows a user to select a needle of appropriate size of gauge or needle length and/or to replace a needle that becomes bent or burred.
- Another advantage of the retractable syringe described herein is that it can accommodate and fully encapsulate on retraction, needles of varying length up to 1.5 inches ( ⁇ 3.8 cm) in length, thereby providing great flexibility to the user.
