The disposable injection syringe is composed of a syringe with a small hole at the front end and a matched piston core rod. The ejector is used to inject or extract a small amount of liquid into areas inaccessible by other methods. When the core rod is pulled out, the liquid or gas is sucked from the small hole at the front end of the needle cylinder, and the liquid or gas is extruded when the core rod is pushed in. The process of extracting or injecting gas or liquid with syringes and syringes is called injection.The disposable syringe can be made of plastic or all glass syringe, and usually has a scale indicating the volume of liquid in the syringe. Glass syringes can be sterilized by autoclave, but because the treatment cost of plastic syringes is low, most modern medical syringes are made of plastic, which further reduces the risk of blood borne diseases. Among intravenous drug users, the spread of diseases, especially HIV and hepatitis, is related to the reuse of needles and syringes.The injector syringe can be made of plastic or all glass syringe, and usually has a scale indicating the volume of liquid in the syringe. Glass syringes can be sterilized by autoclave, but because the treatment cost of plastic syringes is low, most modern medical syringes are made of plastic, which further reduces the risk of blood borne diseases.Test principle of infusion bag permeability tester: designed based on the principle of differential pressure method, the pre-treated sample is placed between the upper and lower test chambers to form a constant differential pressure on both sides of the sample. Under the action of the differential pressure, the gas penetrates from the high-pressure chamber through the film to the low-pressure chamber, monitors the pressure change of the low-pressure chamber, and calculates the barrier parameters of the tested sample.When the core rod is pulled out, the liquid or gas is sucked from the small hole at the front end of the needle cylinder, and the liquid or gas is extruded when the core rod is pushed in. The process of extracting or injecting gas or liquid with disposable syringes and syringes is called injection.
