Device for sterilizing and disinfecting surface of endoscope through plasma

Abstract

The invention discloses a device for sterilizing and disinfecting the surface of an endoscope through plasma. The device comprises a high-voltage electrode, a ground electrode, an insulating medium tube, a lead, a power supply and a high-voltage wire, wherein the ground electrode is made of a conductive metal net; the ground electrode is tightly adhered to the inner wall of the insulating medium tube; the top end of the ground electrode is flush with the top of the insulating medium tube; the bottom end of the ground electrode extends out from the bottom end of the insulating medium tube; the ground electrode is grounded through the lead; the high-voltage electrode is a copper foil or an aluminum foil; the high-voltage electrode is tightly wound on the surface of the outer wall of the insulating medium tube; the upper end and the lower end of the high-voltage electrode are both lower than the opening the insulating medium tube; the high-voltage electrode is connected with the power supply through the high-voltage wire. The device is sleeved by an insulating shell, the shell is of a single-opening tube structure, a screw cap is connected with the top opening of the insulating shell in a sleeve manner, three layers of concentric baffle rings are arranged at the bottom of the insulating shell; the inner diameters of the three layers of the baffle rings are reduced in sequence from top to bottom. The device has the advantages of being simple in structure, convenient to use, low in cost, small in energy consumption, high in efficiency, free of endoscope damage, and the like.

Description

technical field [0001] The invention relates to the field of plasma disinfection, in particular to a plasma disinfection device used for disinfection and sterilization of speculum. Background technique [0002] It is known that the speculum is the latest generation of fiber optic scope, which has the characteristics of clear vision and simple operation, and is widely used in the fields of routine physical examination and minimally invasive surgical treatment of the nose, throat, stomach, and intestinal tract. However, due to the soft material, strong bendability, small diameter, and thin lumen of the speculum itself, it is difficult to clean and disinfect the speculum. At present, the number of clinical fiberscopes is limited, and the cost of one-time use is high, but there are risks of cross-infection when used repeatedly. Therefore, it is necessary to disinfect and sterilize the speculum. The current disinfection method is mainly to use 2% alkaline glutaraldehyde to disin...

AI Technical Summary

Problems solved by technology

Therefore, it is necessary to disinfect and sterilize the speculum. The current disinfection method is mainly to use 2% alkaline glutaraldehyde to disinfect the speculum. There is often a problem of insufficient disinfection time, which seriously affects the disinfection effect and medical quality and safety. Long-term use It is easy to cause adverse effects on the health of medical staff

[0003] In summary, the existing disinfection technology cannot meet medical standards, and a new device dedicated to disinfection and sterilization of speculum is needed
