Problems solved by technology

[0005] In order to overcome that when the needle penetrates the human body, there is always a slight deviation from the selected position, and it is impossible to accurately find the injection position. Moreover, for different body weights, in order to ensure the efficacy of the medicine, the needle needs to penetrate at different depths. The personnel cannot guarantee the accurate penetration depth, thereby affecting the shortcoming of the drug effect. The technical problem of the present invention is: to provide an intramuscular syringe that can reduce the positioning deviation and control the penetration depth of the needle, and can accurately position and control the injection depth.

Embodiment 1

[0039] An intramuscular syringe that can be precisely positioned to control the injection depth, such as Figure 1-6 As shown, it includes an injection needle tube 1 and a measuring cylinder 2. The measuring cylinder 2 is set on the outer left side of the injection needle tube 1. The middle part of the measuring cylinder 2 is slidably connected with the middle part of the injection needle tube 1. Fixed connection.

[0040] Working principle: before use, the medical personnel will suck the medicinal liquid to be injected into the measuring cylinder 2 through the needle, and the medical personnel will judge the depth of the injection and the force required for the injection according to the experience, and then find the injection position, with an appropriate Force the injection needle into the body, inject the liquid medicine into the human body, and complete the injection.

Embodiment 2

[0042] On the basis of Example 1, such as Figure 2-6 As shown, an adjustment mechanism is also included, and the adjustment mechanism includes an adjustment tube 3, a fixed sleeve 4, a fixed ring 401, a stretchable elastic member, a connecting rod 403, a support frame 404, a support frame 405, a pressing plate 406, a connecting column 4061, The elastic part and the buckle 408, the adjusting tube 3 is threadedly connected to the left side of the measuring cylinder 2, the fixing sleeve 4 is fixedly installed on the right side of the injection needle tube 1, the fixing ring 401 is fixedly installed on the right side of the measuring cylinder 2, and the stretching elastic part The right end is fixedly installed on the left side of the front and rear raised parts of the fixed sleeve 4, the left end of the stretch elastic member is fixedly connected with the right side of the front and rear raised parts of the fixed ring 401, and the right ends of the two connecting rods 403 are res...

Embodiment 3

[0045] On the basis of Example 2, such as image 3 As shown, the fixed sleeve 4 includes a first spring 4b, a fixed block 4a and a splint 4c, the outer ends of the sixteen first springs 4b are fixedly installed inside the fixed sleeve 4, and the sixteen fixed blocks 4a are fixedly installed on the fixed sleeve 4 inside, the fixed block 4a is fixedly connected with the outer end of the first spring 4b, there are four splints 4c, and each splint 4c is fixedly installed on the inner ends of the four first springs 4b respectively, and the splint 4c is fixedly connected with the injection needle tube 1.

[0046]Working principle: Different patients need to inject different medicines, and the size of the injection needle tube 1 is also different. When changing different needle tubes, the first spring 4b in the fixed sleeve 4 will be compressed to different degrees due to the size of the needle tube. The rebound force of the first spring 4b fixes the needle tube, which is convenient ...

Abstract

The invention relates to an intramuscular injector, in particular to an intramuscular injector capable of accurately positioning and controlling the injection depth. The invention aims to solve the technical problem of providing the intramuscular injector capable of accurately positioning and controlling the injection depth, which can reduce positioning deviation and control the penetration depthof a needle head. The intramuscular injector capable of accurately positioning and controlling the injection depth provided by the technical scheme of the invention comprises an injection needle tubeand a measuring cylinder, wherein the measuring cylinder sleeves the outer side of the injection needle tube, the middle portion of the measuring cylinder is in sliding connection with the middle portion of the injection needle tube, and one end of the measuring cylinder is fixedly connected with one side of the injection needle tube. Through threaded connection of the adjusting tube and the measuring cylinder, movement of the adjusting tube is achieved, so that the penetration depth of the injection needle head is determined, and the injection process of different crowds is facilitated.

Description

technical field [0001] The invention relates to an intramuscular injector, in particular to an intramuscular injector capable of precisely positioning and controlling injection depth. Background technique [0002] Syringes are commonly used treatment tools. Medical staff inject the medicinal liquid needed by the patient into the syringe, and then directly inject the medicinal liquid into the human muscle through the syringe. The medicinal liquid directly reaches the inside of the human body through the human muscle, which is better than oral treatment. [0003] When a person is sick and needs to inject medicine into the hospital, the medical staff usually hold the syringe to select the injection position based on experience, and then use the inertial force to pierce the needle of the syringe into the human body. There is a slight deviation in the position, especially for children, who are afraid of pain and are easy to avoid when giving an injection. The medical staff cannot...
