    FIELD OF TECHNIQUE
    [001] The present invention relates generally to safety systems for syringes and, more specifically, to a needle shield for a syringe that includes an automatically activated shield to cover a syringe needle. FUNDAMENTALS OF THE INVENTION
    [002] Medicines are often dispensed with the use of a medicine cartridge, such as a glass syringe, which has a barrel with a needle at one end and a plunger slidably inserted at the other end and coupled to a stopper. rubber. Such cartridges are often referred to as “pre-filled syringes” because they can contain a specific dosage or volume of medication when they are initially dispensed, as compared to conventional syringes that are dispensed empty and filled by the user before giving an injection.
    [003] The glass syringe and rubber plug have provided, for years, an ideal drug storage container that has unique properties of oxygen impermeability, low extractability, biocompatibility, durability, etc. However, both are formed by processes that do not lend themselves to tight geometric tolerances. Tight tolerances were not originally required for these devices because they were not mechanically used with other devices.
    [004] Due to the risk of communicable diseases, several syringes and adapters have been developed that are intended to prevent accidental needle sticks and/or inadvertent reuse of a syringe. Conventional passive needle stick safety devices for pre-filled syringes must mount on the syringe but not excessively interfere with the force required to move the plunger rod during injection nor impede the complete plunger rod travel. The safety mechanism must necessarily be triggered towards the end of drug delivery or injection (ie, near the end of the plunger rod path). However, as virtually all safety devices locate the syringe against the safety device at a point under the syringe finger flange, the operability of the safety device tends to be dependent on syringe and plug tolerances.
    [005] In addition, as conventional passive needle prick safety devices for pre-filled syringes tend to mount on the syringe barrel, the safety devices tend to obscure the contents of the syringe and must be applied after filling the syringe. .
    [006] Pre-filled syringes can be shipped to customers as ready-to-fill syringes, which are syringes that have been thoroughly cleaned inside and out after the process of forming and attaching a needle has been completed, and then placed in sealed tubes which are then sterilized and shipped to pharmaceutical customers to fill with a drug. Syringe tubes can hold from 100 to 160 syringes, each with geometric spacing and access that is consistent with established syringe handling equipment. A safety device applied to the syringe must not obscure the optical inspection systems that are in place to check the syringes before filling them with medication.
    [007] Therefore, it is desirable to have a needle guard for a ready-to-fill syringe that has a safety device trigger mechanism independent of syringe and plug tolerances, and that mounts to the syringe without adversely affecting the position of the syringe with respect to the syringe handling tube or the way the handling equipment transports the syringes during filling and packaging does not impede the inspection processes. SUMMARY OF THE INVENTION
    [008] The systems and methods described herein are directed to a needle guard for a syringe that has the safety device trigger mechanism independent of syringe and plug tolerances. A needle protection device that releases the contact trigger described herein is a needle stick device designed to be attached to the distal end of a ready-to-fill syringe. The needle guard device includes a locking collar and a movable device guard with respect to the locking collar. The device guard is biased with respect to the locking ring by an elastic spring coupled between the device guard and the locking ring. The locking collar faces a syringe neck and recess to secure the needle guard device to the ready-to-fill syringe. With the removal of a rigid needle shield subassembly comprising both rigid and soft needle shield components, the device shield is free to move proximally along the syringe neck and interact with the locking collar triggering the shield. device for moving with respect to the locking collar from a first configuration, where the device shield is movable to expose a sharp needle to a second configuration where the needle is fixedly protected and covered.
    [009] In use, a device user removes the rigid needle shield subassembly, inserts the sharp syringe, such as a needle, into an injection site, and pushes down on the syringe past the device shield initial contact point. with the skin, moving the needle shield proximally along the locking ring. As the needle guard moves proximally along the locking collar, the locking collar's rotation arms interact with angled notches in the device guard causing the device guard to rotate relative to the locking collar and disengage a or more keys in the device guard from one or more keyways in the locking collar, triggering the device guard to move from the first configuration where the device guard is retractable to expose a sharp syringe, to a second configuration where the device shield is fixedly positioned to the sharp syringe shield or cover.

    [050] The systems and methods described here are directed to a needle guard for a syringe that has the safety device trigger mechanism independent of the syringe geometry. Returning to the figures, Figures 1 to 38 show embodiments of a contact trigger release needle guard. The needle guard described here is a needle-stick safety device designed to be attached to the distal end of a pre-filled syringe in its ready-to-fill state. As illustrated in Figure 1, a needle prick safety device or needle shield 100 is designed to be attached to the distal end of a syringe 50 in its ready-to-fill state. Device 100 comprises a locking collar 10, a device shield 20, a flexible interconnect 30 and a rigid needle shield 40 comprising a rigid outer component 41, and a soft inner component 42 (see Figures 7, 9 and 10) . In a preferred embodiment, the locking ring 10, the device guard 20, the flexible interconnect 30 are produced in an injection molding process. The process consists of injection molding the locking collar 10 and the device guard 20 in a first shot of injection molding with a single polymeric material. As depicted in Figure 2, the two parts can be connected via a thin bridge 60 of material or via a caster system in what is typically known as a family mold. A second injection molding shot consists of a flexible material such as thermoplastic elastomer (TPE), which produces a flexible interconnect 30 that physically connects locking collar 10 to device guard 20 as illustrated in Figure 3. During the molding process by injection the flexible interconnect 30 typically connects the locking ring 10 and the device guard 20. Alternatively, the locking ring 10 and the device guard 20 can be designed so that when the flexible interconnect 30 is injection molded, it is created a physical mechanical link between the parts. The last step in the process is to remove the bridge 60. The safety device is depicted in Figure 4 without the bridge 60.
    [051] As illustrated in Figures 5 and 6, when the safety device 100 is mounted the locking ring 20 is pushed and inserted into the device guard 20. The step is made possible by the flexibility of the flexible interconnect 30, which is coupled to the and positioned between the locking collar 10 and the device guard 20.
    [052] Returning to Figures 7, 8 and 9, the device 100 is shown mounted on the syringe 50 via a recess 52 in the syringe neck 53 and the locking collar 11 located on the inner diameter of the locking collar 10. The rigid needle shield 40 is secured to the distal end of the syringe 54. As illustrated in Figures 10 and 11, the rigid needle shield 40 comprises an outer rigid thermoplastic 41, and a soft inner elastomeric needle shield 42, as currently marketed and often used in pre-filled glass syringes to protect the needle and drug such as, for example, Stelmi rigid needle shield or BD rigid needle shield. The distal end of syringe 54 is designed to be identical to a standard 1ml long pre-filled glass syringe. Consequently, the rigid needle shield 40 functions in the same manner as current pre-filled syringe rigid needle shield systems, protecting both the sharp needle 51 and the contents of the syringe 50 by creating a seal between the shielding member. soft needle 41 and ampoule 55 of the syringe, and soft needle guard component 42 and sharp needle 51.
    [053] The rigid needle guard 40 also contains a clamping section 43 that extends from the outer rigid portion 41, which protrudes from the underside of the device guard 20 as described in Figure 7. The clamp 43 is available for user to attach and remove rigid needle shield 40 before using syringe 50 and safety device 100. After removal of rigid needle shield 40, syringe 50 and safety device 100 are ready for injection of medicine.
    [054] Returning to Figure 12, to perform an inspection a user must place the distal end 28 of the device guard 20 against the injection site 70 and push the syringe 50 to insert the needle 51. as the syringe 50 is pushed in the distal direction, the device guard 20 travels in the proximal direction along the syringe 50. As shown in Figure 13, the flexible interconnect 30 is attached or secured to the distal end of the locking collar 10 and the proximal end of the device guard 20 . and as a result, as the syringe 50 is pushed in the distal direction, the locking collar 10, which is coupled to the syringe 50, travels in the distal direction with respect to the device guard 20 causing the flexible interconnect 30 to be stretched. , thereby storing energy, and therefore acting as a spring.
    [055] During the initial few millimeters of travel of the device guard 20 in the proximal direction along the syringe 50, a locking arm of device guard 22 travels upwards or approximately along a ramp 12 located in the locking collar 10 as illustrated in Figure 14. Consequently, the locking arm of device guard 22 flexes and will travel upward or approximately along syringe 50 flexing during insertion of needle 51 to injection site 70. Returning to Figures 15 and 16 , an angled cutout 23 is shown in the device guard 20 and a swivel arm 14 is shown in the locking collar 10. The swivel arm 14 is aligned with the starting point (Point A) of the angled cutout 23. As shown in the Figures 17 and 18, prior to insertion of the needle 51, the locking collar 10 and the device guard 20 are pivotally coupled by means of keys 25 which extend axially along the inner portion. that of the device guard 20 and the keyways 15 located on the outer periphery of the locking collar 10. Returning to Figures 19 and 20, when the device guard 20 has already traveled upwards or approximately along the syringe 50 a sufficient predetermined distance , just as the pivot arm 14 of the locking ring 10 reaches point A of the angled indent 23, the pivot arm 14, which is in a flexed state while within the device guard 20, will retract to the angled indent 23 in the device guard 20. As a result of the contact now made between the angled cut-out surface 26 and the lower edge 16 of the rotating arm 14, and the continuous proximal movement of the device guard 20 with respect to the syringe 50, the device guard 20 and the locking ring 10 will begin to rotate with respect to each other. As described in Figures 21 and 22, as device shield 20 and locking collar 10 rotate with respect to each other as needle 51 is also inserted into injection site 70, an angled or beveled surface 27 of the device guard key 25 and a cutout 28 within device guard 20 allows device guard key 25 to flex out of keyway 15 and travel over a locking ring tab 17.
    [056] Referring to Figures 23 and 24, at the point where the rotation arm of the locking ring 14 reaches Point B at the angled cutout 23, the needle 51 is fully inserted into the injection site 70, the device guard 20 it can no longer move up or in the proximal direction along the syringe 50 due to the interface between the lower surface 16 of the rotation arm 14 and the lower surface 29 of the angled cutout 23, and, as illustrated in Figure 25, the protection of device 20 and locking collar 10 are rotatably secured as key 25 is allowed to retract to engage with a locking collar tab 17. It is preferable that device guard 20 and locking collar 10 are rotatably secured therein. point of device use, otherwise the twist created in flexible interconnect 30 as a result of twisting device shield 20 with respect to locking collar 10 during insertion of needle 51 tends to force device shield 20 and locking rod 10 back to its original orientations with respect to each other upon removal of needle 51. Such an occurrence tends to prevent device guard 20 from properly locking in the protected position upon complete removal of needle 51 from injection site 70 .
    [057] After the injection is applied and the syringe 50 is pulled away from the injection site 70, the tension or energy stored in the flexible interconnect 30 forces the device guard 20 to move in the distal direction back down the syringe 50. As a result, device guard 20 is always protecting needle 51, and therefore protecting the administrator from sticking with needle 51. Returning to Figures 26 and 27, as device guard 20 is forced back into the At the distal end of the syringe 50, the swivel arm 14 travels in a channel 65 within the device shield 20. The purpose of the channel 65 is to keep the swivel arm 14 from being required to flex and thereby create a frictional force resistance between the rotation arm 14 and the device shield 20 during the covering of the needle 51.
    [058] Furthermore, as illustrated in Figures 28 and 29, as the device guard 20 is forced back toward the distal end of the syringe 50 as a result of the force coming from the stretched flexible interconnect 30, the locking arm of the device guard 22 travels in a flexible state along the surface of the syringe 50 and then along a tab 18 on the locking collar 10. As described in Figures 30 and 31, as the locking arm of the device guard 22 traveling distally down the locking ring flange 18 will find a recess 19 in the locking ring, which will engage due to its fixed state. The interface between the upper or proximal edge 66 of the locking arm of the device guard 22 and the upper or distal surface 68 of the locking ring recess 19 causes the device guard 22 to be in a locked state, permanently protecting and covering the needle 51. The interface between the lower part of the locking arm 22 and the lower surface of the locking ring recess 19 prevents further distal movement of the device guard 20 with respect to the syringe 50.
    [059] Returning to Figures 32 and 33, an alternative embodiment is illustrated to include a different device locking method. A locking ring 150 is mounted on the locking collar 110 at its distal end and prior to use of the device. The locking ring 150 contains two tabs 151 on each side that sit within two channels 121 within the device guard 120. As illustrated in Figure 34, during needle insertion the needle guard 120 moves in a proximal direction from the injection site to syringe barrel 160 such that locking ring tabs 151 slide into device guard channels 121 until bottom surface 128 of the channels contact locking ring tabs 151. device 120 continues to move the syringe barrel 120 upwards and the needle also penetrates the injection site, the locking ring 150, as shown in Figure 35, is carried with the device guard 120 to the axis 112 of the locking ring 110 where it meets an inclined ramp 114 on each side of the locking collar 110 and flexes over the inclined ramp 114. As shown in Figure 36, the locking ring 150 is molded to the letter C which makes it flexible.
    [060] Returning to Figures 37A and 37B, at the top of the sloping ramp 114 of the locking ring 110 includes a flat surface 115. Once the locking ring 150 fully rises the slanted ramp 114 will relax back to its original shape. with its lower surface 154 resting on the flat surface 115 of the inclined ramp 114. The protrusions 156 (one on each side) on the locking ring 150 are joined with and match the external dimensions of the syringe barrel 160. They are also in vertical alignment with the device guard locking arms 122. After the injection is completed and the syringe is pulled from the injection site, the device guard 120 will move distally back under the syringe barrel 160 as described in the previous embodiment due to to the elasticity and spring force generated by the flexible interconnect 130. To securely lock the device, the locking arms of the device guard 122, in a state of f Flexible shaft when the needle is being removed from the injection site, will transfer contact from syringe barrel 160 to locking ring bosses 156, as illustrated in Figures 38A and 38B, then snap into place under bosses 156. illustrated in Figure 32, the locking ring 150 are vertically constrained by the flat surface 115 of the locking ring sloping ramps 114 and the lower surface of the locking ring flap 119, the shield 120 will be unable to move up and down with respect to syringe barrel 160, consequently blocking the device and protecting the user from accidental needle prick.
