Problems solved by technology

Everyone has a fear of needles. It is inevitable that there will be insufficient strength when inserting needles by yourself, resulting in the needle not being inserted or not in place, and it will have a certain psychological burden on the patient, and needles often appear. , unable to adhere to the drug injection, leading to aggravation of the patient's condition
Moreover, manual needle injection is inefficient and prone to pinhole infection

Embodiment 1

[0044] like Figure 1-14 As shown, an automatic needle sticking aid for injection needles includes a rotary switch 1 , a casing 2 that is clamped with the rotary switch 1 , and a needle handle clamping device 3 arranged in the casing 2 . Both the rotary switch 1 and the housing 2 are hollow cylindrical structures. A fixed table is arranged in the rotary switch 1 ; the outer diameter of the limit cover 6 is larger than the inner diameter of the fixed table and smaller than the inner diameter of the rotary switch 1 .

[0045] like Figure 15 As shown, the injection needle 9 includes a needle handle 91 , an L-shaped needle head 92 mounted in the needle handle 91 and an infusion tube 93 in communication with the needle handle 91 .

[0046] On the outer side of the rotary switch 1 are provided a circumferential clamping groove 11 and two symmetrically arranged clamping ports 12 communicating with the clamping grooves 11 , and two mounting holes 16 with downward openings are symme...

Embodiment 2

[0058] like Figure 13 As shown, the difference between this embodiment and Embodiment 1 is that the outer walls of the left clip portion 81 and the right clip portion 82 are respectively provided with escape grooves 85, and the escape grooves 85 and the guide The holes 72 are arranged in parallel. Other structures are consistent with Example 1.

[0059] The avoidance groove 85 plays the role of limiting the left and right clips 82. When the guide block 28 enters the avoidance groove 85, under the action of the clip return spring 87, the left and right clips 82 are separated by a certain distance to facilitate the insertion and removal of the needle handle. Released, the clip return spring 87 is in the original length or compressed state; when the guide block 28 leaves the escape groove 85, the two guide blocks 28 clamp the left and right clamping parts 82, so that the left and right clamping parts 82 clamp the needle handle . By arranging the avoidance groove 85, the needl...

Embodiment 3

[0061] like Figure 11 As shown, compared with Embodiment 2, the difference between this embodiment is that an arc-shaped limiting top plate 61 is provided on the inner top plate of the limiting cover 6, and the limiting top plate 61 is located at the edge of the clamping part of the needle handle. Directly above. Other structures are consistent with Example 2.

[0062] The top of the needle handle clamping part is limited to further increase the stability of the needle.

Abstract

The invention discloses an automatic needle sticking aid for injection needles, which comprises a rotary switch, a casing connected with the rotary switch, and a needle handle clamping device arranged in the casing; the rotary switch and the casing are both hollow cylindrical structures; On the outer side of the rotary switch, there is a circular clamping groove and two symmetrically arranged card interfaces that communicate with the clamping grooves; two clamping joints are symmetrically arranged on the inner side wall above the casing, and the clamping joints rotate through the card interfaces. Enter the snap slot to snap the rotary switch and the housing together. The invention realizes the rapid implantation of the needle by rotating the rotary switch, improves the use efficiency, relieves the pain of puncturing the needle, and reduces the infection rate of the needle hole.

Description

technical field [0001] The invention relates to the technical field of medicament injection supplies, in particular to an automatic needle sticking aid for injection needles. Background technique [0002] In the case of drug injection, the injection needle is usually used for direct injection. For patients with high blood sugar, daily insulin injection is required, and the injection process usually needs to be completed by itself. Everyone will have a psychological fear of needles. When needles are inserted by themselves, it is inevitable that there will be insufficient strength, which will cause the needles to not go in or the needles are not in place, and it will cause a certain burden on the patient's psychology, and often feel tired of needles , can not adhere to the drug injection, resulting in aggravation of the patient's condition. Moreover, the manual needle insertion method has low efficiency and is likely to cause pinhole infection. SUMMARY OF THE INVENTION [...
