Description

Injector handle capable of adapting to different hands

Technical Field

The utility model relates to the technical field of syringe handles, in particular to a syringe handle capable of adapting to different hands.

Background

The syringe is a common medical device and as early as the 15 th century, italian people put forward the principle of the syringe in Katheiler. Is mainly used for injecting liquid medicine or extracting liquid.

The existing injector is usually composed of an injection tube, a needle tube, a piston and a push rod, but the existing handle made of the push rod may have a longer stroke of the injection tube, so that the stroke of the handle is longer, when the handle is completely pulled out, part of users are affected by too little hand, the end part of the handle cannot be pressed, and the problem of difficult use occurs.

Disclosure of Invention

The present utility model is directed to a syringe handle adaptable to different hands, so as to solve the above-mentioned problems of the related art.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides an adaptable different hand-type syringe handles, includes syringe main part and handle main part, the handle main part includes push rod, spacing ring, first push pedal and second push pedal, spacing ring screw thread sets up the surface of push rod, just first push pedal sets up the one end of push rod, the second push pedal sets up the surface of push rod.

Preferably, the injector main body comprises a cylinder body, a needle tube main body and a piston main body, wherein the needle tube main body is arranged on one side of the cylinder body, the piston main body is arranged in the cylinder body in a sliding manner, and the other end of the push rod is connected with one side of the piston main body.

Preferably, the surface of the push rod main body is provided with external threads, and the limiting ring is connected with the surface of the push rod main body through the external threads.

Preferably, a sliding hole is formed in the surface of the second push plate, and the push rod is slidably arranged in the sliding hole.

Compared with the prior art, the utility model has the beneficial effects that: the utility model is provided with the push rod, the limiting ring, the first push plate and the second push plate, when in use, the second push plate and the first push plate can both press the push rod to push the piston main body to act, and meanwhile, the limiting ring is connected with the push rod through the external threads, so that the fixed position of the limiting ring on the surface of the push rod can be adjusted, thereby meeting the use of different hand groups.

Drawings

FIG. 1 is a schematic view of the external structure of the present utility model;

FIG. 2 is a schematic view of a front cross-sectional structure of the present utility model;

in the figure: 1. a syringe body; 101. a cylinder; 102. a needle tube main body; 103. a piston body; 2. a handle body; 201. a push rod; 202. a limiting ring; 203. a first push plate; 204. a second push plate; 3. and (5) external threads.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, the present utility model provides a technical solution: the utility model provides an adaptable different hand-type syringe handles, includes syringe main part 1 and handle main part 2, and handle main part 2 includes push rod 201, spacing ring 202, first push pedal 203 and second push pedal 204, and spacing ring 202 screw thread sets up in the surface of push rod 201, and first push pedal 203 sets up in the one end of push rod 201, and second push pedal 204 sets up in the surface of push rod 201;

the injector body 1 comprises a cylinder 101, a needle tube body 102 and a piston body 103, wherein the needle tube body 102 is arranged on one side of the cylinder 101, the piston body 103 is arranged in the cylinder 101 in a sliding mode, the other end of the push rod 201 is connected with one side of the piston body 103, external threads 3 are arranged on the surface of the push rod 201 body, a limiting ring 202 is connected with the surface of the push rod 201 body through the external threads 3, a sliding hole is formed in the surface of the second push plate 204, and the push rod 201 is arranged in the sliding hole in a sliding mode.

Working principle: when the hand shape of a user is smaller, the position of the limiting ring 202 on the surface of the push rod 201 can be adjusted by rotating the limiting ring 202 according to the hand shape of the user, then when the injection syringe is used, the user can push the push rod 201 to drive the piston to act for injection by pressing the second push plate 204 after the second push plate 204 is abutted against the limiting ring 202, when the second push plate 204 moves to the end part of the cylinder 101 along with the push rod 201, the user presses the push plate again to continue injection, at the moment, the limiting ring 202 enters the cylinder 101, and relative sliding occurs between the second push plate 204 and the push rod 201 until the injection is completed. The utility model can meet the use requirements of different hand groups, has good applicability and is convenient to popularize and use.
