Barometric pressure flexible cold plasma jet endoscope sterilizing device and method

Abstract

The invention relates to the field of sterilization in the medical industry, and particularly relates to a barometric pressure flexible cold plasma jet endoscope sterilizing device and a barometric pressure flexible cold plasma jet endoscope sterilizing method. An endoscope is immersed in a conduit type sterilizing region full of a barometric pressure flexible cold plasma jet, the microorganism on the surface of the endoscope is killed by the barometric pressure flexible cold plasma jet, the conduit type sterilizing region is non-closed and is independent from a plasma electrode discharge region, and the plasma electrode discharge region is used for producing the flexible cold plasma jet. The soft or hard endoscopes in different sizes are sterilized by changing the shape and the size of a conduit without changing the structure of an electrode. The sterilizing method does not need complicated vacuum equipment, the cost is low, the efficiency is high, no chemical reagent is needed, the environmental pollution is avoided, and the method is a low-cost high-efficiency green endoscope sterilizing method.

Description

technical field [0001] The invention relates to the field of disinfection and sterilization in the medical industry, in particular to an atmospheric pressure flexible cold plasma jet endoscope sterilization device and method. Background technique [0002] Endoscope is an important medical device used to observe the lumen in human and animals, and has been clinically used in the diagnosis and treatment of many diseases. Before using the endoscope, it needs to be sterilized to prevent cross infection. A variety of methods have been used to sterilize endoscopes, such as high-temperature and high-pressure steam, ethylene oxide fumigation, glutaraldehyde immersion, and low-temperature plasma sterilization. Among them, the high temperature and high pressure steam sterilization temperature is relatively high, which is easy to cause thermal damage to the surface of the endoscope, and it is difficult to effectively inactivate some pathogenic microorganisms. The sterilization proces...

AI Technical Summary

Problems solved by technology

But this device and method need expensive and complicated vacuum equipment, the cost is higher, and in the actual treatment, it is necessary to evacuate first, inject hydrogen peroxide and then sterilize, so the sterilization efficiency will be reduced; in addition, this type of device is difficult to treat many Sterilize long or very thin endoscopes

There is no relevant report on the method of using a relatively simple structure sterilization device and low-cost gas to sterilize endoscopes

In addition, if the plasma electrode discharge area and the sterilization area can be separated, the temperature of the sterilization area can be reduced, and the size of the catheter can be easily changed to adapt to endoscopes of different sizes, but the above-mentioned endoscope sterilization device has not yet been able to accomplish
