Laser-driven needleless injection system

Abstract

An embodiment of the invention discloses a laser-driven needleless injection system. The system comprises an injection device 1, a light path control module, a medicine supply device and a laser generator, wherein the injection device is used for carrying out needleless injection; the laser generator is used for generating laser light; and the light path control module is used for controlling a light path of laser generated by the laser generator, so that the laser can serve as a power source to act on the injection device or act on the skin to pretreat the skin. The medicine supply device isconnected with the injection device and used for supplying medicines to the injection device. The laser-driven needleless injection system in the embodiment of the invention can be used for pretreating the skin, so that the overall injection efficiency of the system is improved, and needleless injection of macromolecular medicines such as hyaluronic acid can also be realized; the defects of low injection dosage control precision, high noise and the like caused by power sources such as a traditional spring and high-pressure gas are avoided; and the aim of integral large-dose injection can be fulfilled by utilizing multiple times of continuous small-dose injection.

Description

technical field [0001] The present invention relates to the relevant technical field of medical injection devices, in particular to a laser-driven needle-free injection system. Background technique [0002] At present, most of the external injection methods used in medical treatment are injection with needles. After the needle penetrates the human skin to reach the designated position, the syringe is pushed to complete the injection process. However, needle injection has safety issues such as cross-infection and needle breakage, and injection experience problems such as severe pain. [0003] In view of the above problems, needle-free injection technology has gradually become a new development trend. Needle-free injector is a medical mechanical system that utilizes an external power source to generate relevant reactions and exert force on the liquid medicine, so that the medicine in the syringe forms a high-speed jet flow, and finally penetrates into various tissues in the s...

Problems solved by technology

[0004] 1. The dosage is too small: the volume of conventional needle-free injection is 0.1-1ml, and 1.5ml is the upper limit of needle-free injection. If the volume is too large, it will cause severe pain at the injection site, and the drug delivery efficiency is obvious reduce;

[0005] 2. Poor working stability: The working stability of spring power is poor, which can easily lead to differences in dosage, affecting the safety and effectiveness of clinical treatment; while high-pressure gas power is likely to generate huge blasting noise;

[0006] 3. There are limitations in the types of drugs that can be injected: Most of the drugs that can be used for needle-free injection are small molecule drugs with strong solubility. For macromolecular drugs such as hyaluronic acid in the cosmetic field, it is still impossible to use needle-free injection technology for injection
