An In Situ Ultraviolet Sterilization System of Intrabody Inserted Catheter

Abstract

An in-situ ultraviolet sterilizing system for an in-body catheter, comprising an ultraviolet light source, an ultraviolet light transmission channel, a light source-channel coupling interface and end fittings, where the ultraviolet light source is connected to one end of the ultraviolet light transmission channel through the light source-channel coupling interface, The end fittings are connected to the other end of the ultraviolet light transmission channel; the ultraviolet light transmission channel and the end fittings extend into the in-body catheter, and the light propagates along the longitudinal direction of the ultraviolet light transmission channel and irradiates into the lumen of the in-body catheter On the surface, the end fittings can reflect or scatter the ultraviolet rays propagating axially along the ultraviolet light transmission channel to the direction of the included angle; the inner wall of the main pipe can be sterilized in situ through the ultraviolet light transmission conduit, and the inner wall of the cross branch pipe can be sterilized through the end fittings Sterilize in situ. The present invention can conform to the shape of the in-body catheter, and has the characteristics of compactness, portability, instant use, and the advantages of high efficiency, energy saving, environmental protection and long service life.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to an in-situ ultraviolet sterilizing system for an internal catheter, especially suitable for in-situ sterilization of a T-shaped biliary drainage tube inserted after common bile duct incision and exploration. Background technique [0002] Biliary tract disease is a common disease in general surgery, and bile duct stones, bile duct cancer and bile duct stricture are the most common. After the operation, a T-shaped tube needs to be indwelled, which can be used to drain bile, eliminate biliary infection, and prevent biliary stricture. Therefore, T-tube drainage is a routine and important basic operation. T-tube refers to a T-shaped drainage tube made of rubber / silicone / latex. Specifically, the T-shaped bile duct drainage tube includes a long-arm catheter and a short-arm catheter, and one end of the long-arm catheter is vertically connected to the middle part of the short-...
