Medical Consumables Knowledge (Syringe) - Analysis of Its Function and Operation

Today, I will share with you the article "Medical Consumables Knowledge (Syringe) - Analysis of Its Function and Operation". Interested friends can learn about it. The creation of syringes is a milestone reform in the medical industry. The entire process of extracting/introducing gas or liquid is called injection. Syringes consist of a needle with a small circular hole in the front and a matching piston rod core. When the core rod is pulled out, liquid or gas is sucked in from the small circular hole in front of the needle. When the core rod is inserted, the liquid/gas is squeezed out of the needle hole, thus completing the injection.

Syringes can also be used for medical equipment and vessels, such as in some chromatographic instruments where injections are made across plastic diaphragms. Injecting gas into capillaries can cause air embolism. The method 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.
