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 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 by autoclaving, but because of the low cost of handling plastic syringes, most modern medical syringes are made of plastic, which further reduces the risk of blood-borne diseases

However, in the prior injector, in use, the injector usually passes a needle through a rubber plug of a medicine bottle and then performs liquid extraction; this method of use draws the particles of the rubber stopper into the needle tube, which may cause the condition of some patients to be worse; in view of the above, a syringe with a cap is provided.
