Description

Ampoule bottle of needleless injector

Technical Field

The utility model relates to the technical field of injectors, in particular to an ampoule bottle of a needleless injector.

Background

The injector is a common medical appliance, the principle of the injector is proposed by Carton Italian in the 15 th century, the gas or liquid is mainly extracted or injected by a needle, the injector can also be used for injecting a medical device, a container and a scientific instrument such as some chromatography through a rubber diaphragm, the appearance of the injector is an epoch-making revolution in the field of the medical appliance, the process of extracting and injecting the gas or the liquid by the needle is called injection, the injector consists of a needle cylinder with a small hole at the front end and a piston core rod matched with the needle cylinder and is used for injecting a small amount of liquid or extracting the liquid into an area which cannot be accessed by other methods or extracting the liquid or the liquid from the area, the liquid or the gas is sucked from the small hole at the front end of the needle cylinder when the core rod is extracted, the liquid or the gas is extruded when the core rod is pushed, the principle of the injector is proposed by Carton Italian in the 15 th century, however, the first human tests were not carried out until 1657 years, the first human test was carried out by the imperial man Boyle and Rene, and the surgeon Abel of the sixteen military, the King of France, Louis, thought to be the inventor of the syringe, the syringe manufactured in 1853, was made of silver, the capacity was only 1 ml, and had a piston rod with external screw threads, the first glass syringe used by the Fragranson of the England, the transparency of the glass was good, the condition of the injected medicine could be observed, the syringe manufactured by using the metal of the glass tube, the syringe could be sterilized by boiling, the needle could be sharpened and sterilized, the syringe was made of plastic, and was thrown away at one time, the risk of infection during injection was greatly reduced, in order to ensure hygiene and prevent cross-infection, the modern syringe mostly made of plastic, and 2 ml of the syringe was generally used, Syringes of 5 ml, 10 ml or 20 ml, occasionally 50 ml or 100 ml, for intradermal injection 1 ml syringes, syringe barrels of plastic or glass and usually provided with a scale indicating the volume of liquid in the syringe, glass syringes can be sterilized by autoclaving, but modern medical syringes are mostly made of plastic because of the lower cost of handling plastic syringes, which further reduces the risk of blood-borne diseases.

The injectors used in the current market are all provided with needles, the needles need to pierce the surface of the skin during injection, so that the pain is brought to people instantly, bleeding can occur immediately after the needles are pulled out after the injection is finished, the medical alcohol cotton needs to be pressed for a few minutes to stop the bleeding, and the phenomenon of bruising and purple even infection can occur to some people, so that the ampoules of the needleless injectors are provided.
