A sealing structure for the temperature measuring soft probe wire on the steam sterilizer

Abstract

The invention discloses a sealing structure of a temperature-measuring soft probe wire on a steam sterilizer that meets the requirements of the sanitary level, including a chuck interface arranged on the sterilizer, and a wire of a temperature-measuring soft probe that passes through the chuck interface. The chuck interface is provided with a sealing card seat, an annular sealing gasket is provided between the sealing card seat and the chuck interface, a through mounting hole is provided in the sealing card seat, and a silica gel sealing block is provided in the mounting hole , the hole wall of the outer section of the installation hole is provided with threads, and the sealing card seat is connected with a compression block that compresses the silicone sealing block through the threads of the installation hole wall, and the silicone sealing block and the compression block are respectively provided with wire holes. The wires of the temperature measuring soft probe pass through the chuck interface and then pass through the inner section of the installation hole, as well as the wire holes on the silicone sealing block and the pressing block.

Description

technical field [0001] The invention relates to a sealing structure of a temperature-measuring soft probe wire on a steam sterilization cabinet. Background technique [0002] With the implementation of the new version of GMP in China ("Good Manufacturing Practice for Drugs (Revised in 2010)"), various pharmaceutical industries that use steam sterilizers are following the requirements of the new version of GMP. In order to improve the hygiene level of the inner chamber of the sterilizer , to reduce the stagnation dead angle, each interface in the sterilization cabinet must meet the requirements of the sanitary level. [0003] The sealing structure of some domestic soft probe wires for temperature measurement adopts packing in the sealing seat for compression sealing. Although it can effectively seal the silicone wire in the probe, there are health risks. Since the sealing material of the inner packing is sealed with raw material belt or asbestos pad, these two types of seali...

[0003] The sealing structure of some domestic soft probe wires for temperature measurement adopts packing in the sealing seat for compression sealing. Although it can effectively seal the silicone wire in the probe, there are health risks.

Since the sealing material of the inner packing is sealed with raw material belt or asbestos pad, these two types of sealing materials have the phenomenon of shedding of fibrous substances, and bacteria are easy to breed in the gap between the raw material belt and the asbestos pad under wet conditions. It is easy to form leakage during long-term use, inconvenient to replace and maintain, and cannot meet the requirements of the current GMP sanitary level
