[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0025] like Figure 1 As shown, the disposable safety injection needle includes a connecting cap 1 and an auxiliary structure. A connector 2 is provided on the top of the connecting cap 1, and a needle 3 extending to the outside of the connector 2 is provided on the inner side of the connector 2.
[0026] The auxiliary structure includes a first hard adhesive tape 4, a second hard adhesive tape 5, and a snap-fit structure. The first hard adhesive tape 4 and the second hard adhesive tape 5 are respectively disposed on the left and right sides of the outer surface of the connecting cover 1, and the snap-fit structure is disposed on the top of the side opposite to the first hard adhesive tape 4 and the second hard adhesive tape 5.
[0027] Specifically, the first hard adhesive tape 4 and the second hard adhesive tape 5 are symmetrically distributed. The bottom of both the first hard adhesive tape 4 and the second hard adhesive tape 5 extends into the interior of the connecting cover 1. The bottom of both the first hard adhesive tape 4 and the second hard adhesive tape 5 is in contact with the inner wall of the connecting cover 1, which does not affect the normal connection between the connecting cover 1 and the syringe.
[0028] In this embodiment, the auxiliary structure is used to protect the needle after injection to prevent punctures.
[0029] like Figure 2-3 As shown, the snap-fit structure includes a positioning block 6, a connecting block 10, and a snap-fit block 11. The positioning block 6 is located on the top of the first hard adhesive tape 4 near the second hard adhesive tape 5, the connecting block 10 is located on the top of the second hard adhesive tape 5 near the first hard adhesive tape 4, and the snap-fit block 11 is located on the side of the connecting block 10 near the positioning block 6.
[0030] Specifically, the snap-fit structure also includes a slot 8 and a hole 9. The slot 8 is located on the top of the positioning block 6, and the hole 9 is located on the side of the slot 8 near the second hard adhesive tape 5. The slot 8 and the snap-fit block 11 are the same size and shape. The snap-fit block 11 snaps into the slot 8. The depth of the slot 8 is greater than the depth of the hole 9. The hole 9 and the connecting block 10 are the same size and shape, which can effectively prevent the snap-fit block 11 from accidentally falling off.
[0031] In this embodiment, the snap-fit structure can shield the needle 3, preventing the needle 3 from being directly exposed to the outside world and improving safety.
[0032] like Figure 2 As shown, the positioning block 6 has a stop block 7 on both the front and back sides of the bottom of the side near the second hard adhesive tape 5, and the needle 3 is located between the two stop blocks 7.
[0033] In this embodiment, the setting of the stop block 7 can effectively prevent the needle 3 from leaking out due to the forward and backward movement of the positioning block 6.
[0034] like Figure 4 As shown, an outer needle cap 12 is provided on the outer surface of the connecting cover 1, and the connecting head 2 and the needle 3 are both located inside the outer needle cap 12.
[0035] In this embodiment, when no injection is being performed, the outer needle cap 12 is used to protect the needle 3, and the outer needle cap 12 can be removed when injection is being performed.
[0036] The method of using this utility model is as follows:
[0037] Before injection, remove the outer needle cap 12 and pull the first hard adhesive tape 4 and the second hard adhesive tape 5 to make them fit against the syringe tube, so as to prevent the first hard adhesive tape 4 and the second hard adhesive tape 5 from contacting the needle 3 or the injection site during injection. After injection, pull the first hard adhesive tape 4 to position the needle 3 between the two stops 7, and then pull the second hard adhesive tape 5 to make the locking block 11 engage with the locking groove 8. The positioning block 6 and the stops 7 can completely cover the tip of the needle 3, so that the outer needle cap 12 does not need to be put back after injection, effectively avoiding needle 3 pricking the hand or other situations.
[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
