Problems solved by technology

If you pinch the skin with the whole hand, it is possible to pinch the muscle and subcutaneous tissue together, resulting in intramuscular injection
At the same time, the force of pinching the skin should be appropriate and should not be too large, otherwise it will cause skin whitening or pain. Therefore, the skin pinching operation is strict and difficult, and it is also affected by the size of the patient and the injection site. Especially for patients with different body types, the subcutaneous The thickness of the tissue is different, so the work intensity of the medical staff is greatly increased, time-consuming and labor-intensive, and even poses safety hazards

Abstract

The invention discloses a syringe, comprising a syringe body and a dosing device, wherein the dosing device comprises a chuck, a T-shaped rod, a transparent outer barrel, a plug, an engaging assemblyand a pressing part. The pressing part comprises a pressing plate and a pressing strip. The engagement assembly includes a first spring and a slider. The T-shaped head of the T-shaped rod is connectedwith the piston rod of the syringe body through a chuck. T-bar outer sleeve transparent cylinder; One end of the transparent outer cylinder is connected with the plug, and a second spring is arrangedin the transparent outer cylinder; One end of the second spring is connected with a T-shaped rod and the other end is connected with a plug. The rod part of the T-shaped rod is provided with a plurality of grooves at equal intervals along the length direction of the T-shaped rod. The other end of the transparent outer cylinder is provided with a through groove; One end of the pressing plate is elastically rotatably connected with the other end of the transparent outer cylinder, the pressing plate is rotatably connected with the pressing strip, and the pressing strip extends into the through groove. The invention has the advantages of flexible structure design, convenient use, accurate quantitative injection, guaranteed medication safety of patients, and greatly reduces the work intensityof medical personnel and patients.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a syringe and an automatic injection system. Background technique [0002] A syringe is a common medical device, which mainly uses a needle to extract or inject gas or liquid. Regular syringes are provided with scales, and medical staff determine the amount of each injection according to the scales. However, it is often difficult to meet the requirements of accuracy by controlling the injection volume of the syringe by looking at the scale, especially for special drugs that require precise dosage, which will cause danger to the lives of patients. At the same time, the speed of manual needle insertion by medical staff is slow, which brings pain to patients. In addition, if multiple continuous quantitative injections of drugs are required, it is not only difficult for medical staff to operate, time-consuming and laborious, but also unable to control the speed of drugs...
