(Summary description)Urinary catheters have brought good news to patients who need indwelling urinary catheters, and are used more and more clinically. However, with the increase in their applications, the difficulty of catheter removal has become more and more common. Especially for long-term indwelling urinary catheters, sometimes due to the aging of the rubber, the balloon lumen will be blocked, and it may cause serious complications when forcibly removed. In order to prevent the aging of the surface of silicone rubber in contact with the human body, oxygen plasma treatment is required on the surface.

1. Catheter treatment

Urinary catheters have brought good news to patients who need indwelling urinary catheters, and are used more and more clinically. However, as their applications increase, it is more and more common that catheters are difficult to remove. Especially for long-term indwelling urinary catheters, sometimes due to the aging of the rubber, the balloon lumen will be blocked, and it may cause serious complications when forcibly removed. In order to prevent the aging of the surface of silicone rubber in contact with the human body, oxygen plasma treatment is required on the surface. Using scanning electron microscope (SEM), infrared spectroscopy (FTIR-ATR) and surface contact angle to study the surface structure, performance and chemical composition of natural rubber latex catheter before and after treatment with oxygen plasma, the results show that after treatment with oxygen plasma The surface of the urinary catheter becomes slippery, and the surface contact angle is increased by 84. Reduce to 67. No harmful groups are generated on the surface, indicating that oxygen plasma treatment is an effective surface treatment method.

In addition, plasma treatment of silicone rubber can be used to increase its surface activity, and then a layer of hydrophobic material that is not easy to age can be coated on the surface, and the effect is also very good.

2. Intravenous infusion set

In the process of using the infusion needle at the end of the infusion set, the needle seat and the needle tube will be detached when they are pulled out. Once detached, blood will flow out of the needle tube. If it is not properly handled in time, it will pose a serious threat to the patient. In order to ensure the occurrence of such accidents, surface treatment of the needle holder is very necessary. The pin holder hole is very small and difficult to deal with by ordinary methods. Plasma is an ionized gas, which can effectively deal with tiny holes. Plasma is used for surface activation and treatment, which can improve the surface activity, increase the bonding strength between it and the needle tube, and ensure that they will not separate. The following picture shows the surface cleaning and activation treatment of the needle seat in the plasma cleaning machine.
