Description

Telescopic syringe extension tube

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a telescopic syringe extension tube.

Background

Syringes are a common medical device. As early as the 15 th century, kathler, italian, proposed the principle of the syringe. Gas or liquid is primarily drawn or injected with a needle. Syringes may also be used for injection through rubber septa in medical devices, containers, scientific instruments such as in some chromatography. The advent of syringes is an epoch-making revolution in the field of medical devices. This process of drawing, injecting gas or liquid with a needle is called injection. The injector consists of a syringe with a small hole at the front end and a matched piston core rod, and is used for injecting a small amount of liquid or extracting the liquid or the liquid from the inaccessible area by other methods, wherein the liquid or gas is sucked from the small hole at the front end of the syringe when the core rod is pulled out, and the liquid or gas is extruded when the core rod is pushed in. Typically, a 2 ml, 5 ml, 10 ml or 20 ml syringe is used, occasionally 50 ml or 100 ml, and a 1 ml syringe is used for intradermal injection. The syringe barrel may be plastic or glass and is typically provided with a graduated indicator of the volume of fluid in the syringe. Glass syringes can be sterilized with an autoclave, but because of the low cost of disposal of plastic syringes, most modern medical syringes are made of plastic, which further reduces the risk of blood-borne diseases.

However, the structure and the function of the existing syringe are simple and single, on one hand, when medical staff use most of the existing syringes to inject liquid medicine to patients, if the medical staff need to add medicine to the patients again to inject, the needle head needs to be pulled out and then the liquid medicine is sucked from the medicine bottle, so that not only are complicated operation steps brought to the medical staff, but also unnecessary injuries are brought to the patients, the comfort level of the patients is greatly reduced, on the other hand, because some existing syringes have single structures, the application range of the syringes is easily limited, and the flexibility of the syringes in use is further reduced.

Accordingly, those skilled in the art have provided a retractable syringe extension tube to solve the problems set forth in the background art described above.
