In the process of using the infusion needle at the end of the IV infusion set, when the medical staff pulls it out, there may be a detachment between the needle base and the needle tube. Once detached, blood will flow out of the needle tube. If it is not handled in time, it will cause serious damage to the patient. Threatened. In order to avoid such accidents, it is necessary for hospitals to perform plasma surface treatment on the needle seat.

The needle seat hole is very small, and it is difficult to deal with the ordinary method, but the plasma cleaning machine can solve this problem well, because the plasma is a gas in the ion state, and it can also effectively deal with the tiny holes. Plasma performs surface activation treatment on it, which can improve surface activity and increase the bonding strength between it and the needle tube to ensure that they will not separate.

Biological materials usually exhibit low surface energy and chemical inertness. In order to minimize surface fouling and undesirable surface interactions and improve the performance of the materials, plasma cleaning machines are usually used for treatment. The plasma cleaner effectively increases the hydrophilicity of the surface and improves the adhesion of subsequent coatings and adsorption materials.
