Mechanical transmission mode of needleless injector

Abstract

The invention discloses a mechanical transmission mode of a needleless injector, and belongs to the field of medical instruments. The device comprises a voice coil motor module, a guide module, a reading module, an injection module and a handle module, the voice coil motor module provides a power source, the guiding module provides a guiding effect for the voice coil motor module, the reading module measures the movement stroke of the voice coil motor module, the injection module, the guiding module and the voice coil motor module jointly achieve a series of actions of sucking liquid medicine, removing bubbles and injecting the liquid medicine, and the handle module provides convenience for operators. The voice coil motor is adopted as a power source, controllability of driving force in the injection process can be improved, accurate adjustment of dosage can be conducted, injection of different doses can be conducted for different crowds, the injector has good adaptability, injection efficiency can be improved, convenience is provided for crowds terrorist of needles, the pricking feeling in the injection process is reduced, and operation is convenient and simple.

Description

technical field [0001] The invention relates to a needle-free injector, which belongs to the field of medical equipment, in particular to a mechanical transmission mode of the needle-free injector. Background technique [0002] As a commonly used means of drug delivery, traditional syringes with needles can quickly make drugs work in the body. It provides patients with many conveniences in seeking medical treatment and administering medicines, and at the same time plays an irreplaceable role in promoting human health. However, with the continuous innovation of biomedical technology and the improvement of human medical and health standards, there are some disadvantages in the actual use of syringes with needles. For example, needles entering human tissues can easily cause local skin damage, bleeding, pain, etc., and long-term use may cause adverse conditions such as subcutaneous fat tissue nodules and muscle atrophy. Most patients, especially children, will have fear and in...

AI Technical Summary

Problems solved by technology

The injection dose and injection depth of needle-free syringes currently on the market are uncontrollable, which limits the scope of application

In particular, insulin needle-free syringes can only be injected at a fixed dose to a fixed depth, causing inconvenience to patients and medical staff
