HIGH-TEMPERATURE STERILIZATION DEVICE FOR OBSTETRICS AND GYNECOLOGY INSTRUMENTS

Abstract

The present invention relates to the technical field of sterilization equipment. A high-temperature sterilization device for obstetrics and gynecology instruments, including a base, is provided. A support frame is fixedly connected to a top of the base; fixing frames are fixedly connected to both ends of a top of the support frame, and a same sterilization chamber is fixedly connected between the two fixing frames, with one end of the sterilization chamber provided with a sealing door, and a side of an inner wall of the sterilization chamber away from the sealing door fixedly connected with a fixing plate; a plurality of placement mechanisms are provided at both ends of a side of the fixing plate near the sealing door.In the present invention, the interior of the device adopts a separated design of the hanging mechanism and the placement mechanism, thereby avoiding stacking, collisions and entanglement of instruments, thoroughly eliminating sterilization dead angles, ensuring uniform steam circulation, and improving sterilization thoroughness. With the integrated design of steam generation, delivery, and condensate return, which enables efficient utilization of thermal energy and recovery of condensate water, together with precise temperature and pressure monitoring and automatic control, the device operates stably, safely, and reliably, thereby comprehensively improving the sterilization efficiency and use safety of obstetrics and gynecology instruments.
