Electric needleless injector

Abstract

The invention discloses an electric needleless injector, and relates to the field of injectors. The electric needleless injector comprises an injector shell and an injection key; one end of the injector shell is provided with an injection port; the other end of the injector shell is provided with a charging interface; the outer wall of the injector shell is provided with a medicine tube access port; one end, close to the injection port, of the injector shell is provided with a pressurizing indicator lamp; a power switch, an electric quantity display screen and the injection key are inlaid in the outer wall of the injector shell; and the outer wall, close to the charging interface, of the injector shell is provided with an injection completion indicator lamp. According to the invention, painless injection is achieved; an injection hole is small; the injection speed is very rapid; a user cannot feel pain; the electric needleless injector does not have a traditional needle, so that the user cannot resist the injector mentally; and the electric needleless injector is simple to operate, small in size and convenient to carry, can be used anytime and anywhere, accelerates drug absorption, disperses drugs to subcutaneous tissues, takes effect quickly, reduces the infection risk, and reduces the use cost.

Description

technical field [0001] The invention relates to the field of injectors, in particular to an electric needle-free injector. Background technique [0002] A syringe is a common medical device. As early as the 15th century, the Italian Catinelle proposed the principle of the syringe. The gas or liquid is withdrawn or injected mainly with a needle. Syringes are also used in medical equipment, containers, and scientific instruments such as some chromatography to inject through a rubber septum. The emergence of syringes is an epoch-making revolution in the field of medical appliances. The process of withdrawing and injecting gas or liquid with a needle is called injection. The syringe consists of a syringe with a small hole at the front end and a matching piston core rod, which is used to inject a small amount of liquid or inject it into areas that are inaccessible by other methods or withdraw it from those places. When the core rod is pulled out, the liquid Or the gas is inh...

Problems solved by technology

[0005] The purpose of the present invention is to provide an electric needle-free injector to solve the above-mentioned background technology. However, there are many needle-free injectors in the market, but generally the existing needle-free injectors are manually pressurized. To perform the injection operation, such an injection operation is time-consuming and laborious w
