Abstract

The invention discloses an automatic injection injector with the adjustable puncture depth. The injector comprises an injector body, the injector body comprises a needle tubing, and the needle tubingmovably sleeves a syringe; a piston is movably installed in the syringe, a press block is fixedly installed on a core rod and movably installed in a press block slide channel in the syringe, and a pushing block is further fixedly installed on the core rod and movably installed in a sawtooth-shaped slide channel in the syringe; fastening rotary knobs are installed on fixing bases, the fixing basesmovably sleeve extrusion rods, and thread adjustment rotary knobs are movably installed on the extrusion rods; stirring rods are further fixedly installed on the extrusion rods and movably connected with the pushing block. According to the automatic injection injector, the injection depth can be adjusted, medicine pushing and injection are automatically conducted after pricking is conducted, the situation is avoided that medical personnel inject a medicine solution too deeply or too shallowly, the injection force is stable, the operation difficulty of medical personnel is lowered, and the painof patients is relieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatic injection syringe with adjustable puncture depth. Background technique [0002] A medical syringe is a common medical device, which mainly uses a needle to extract liquid medicine, and sends the medicine into the patient's body through a push injection, so as to achieve the therapeutic effect. Most of the existing injection needles use the injection method of direct injection , due to the lack of control by medical personnel, it is difficult to accurately control the injection depth, resulting in inaccurate injection. At the same time, because the needle is outside and there is no protective device, medical personnel are likely to cause self-injury when using it. [0003] In order to solve the above-mentioned problems, a needle hidden syringe with an adjustable injection depth in the prior art with the application number "CN201611038414.9" includes an injecti...
