Small Knowledge Of Medical Consumables (Syringe) - Analysis Of Its Function And Operation

The creation of syringes is a landmark reform in the medical industry. The whole process of extracting/introducing gas or liquid is called injection. The syringe is composed of a needle with a small round hole in the front and a matching piston rod core rod. When the core rod is pulled out, the liquid or gas is sucked in from the small round hole in front of the needle. When the core rod is sent in, the liquid/gas is squeezed out from the needle hole to complete the injection.

 

Syringes can also be used for medical equipment and utensils, for example, in some chromatographic instruments and equipment to inject across the plastic diaphragm. Injecting gas into capillaries will cause air embolism. The way to remove gas from the syringe to prevent blood vessel blockage is to invert the syringe, gently tap it, and then squeeze out a little liquid before injecting it into the blood.
