Description

Technical Field

[0001] The utility model relates to the technical field of medical sterilization, in particular to a sterilization chamber of a small vacuum sterilizer. Background Art

[0002] Cassette sterilizers sterilize by inserting an external sterilization cassette (i.e., the sterilization chamber) into the sterilizer. While this design allows for convenient instrument loading and rapid cooling, it cannot perform Class B sterilization cycles, which are suitable for sterilizing packaged or unpackaged loads (solid, hollow, and porous). Pulsating vacuum pressure steam sterilizers sterilize medical devices that are resistant to high temperatures and moisture by repeatedly pumping and refilling the sterilization chamber (reaching a certain vacuum level before saturating the chamber with steam) to a set pressure and temperature.

[0003] The publication number CN212730444U is a sterilization chamber mechanism of a small pulsating vacuum sterilizer. The sterilization chamber mechanism is used to place medical devices to be sterilized and provide a sealed sterilization space for the medical devices to be sterilized. The sterilization chamber mechanism includes a chamber body and a chamber door located at the opening of the chamber body. The chamber door can slide closer or farther away from the chamber body. The sterilization chamber mechanism also includes a tray rack that provides load-bearing support for the medical devices placed inside the chamber body. The chamber door is fixedly connected to one end of the tray rack.

[0004] Although the above scheme has many benefits, it also has the following disadvantages: the medical devices can be placed on the tray rack, but the number of tray racks that can be placed is limited, and it cannot meet the needs of placing and sterilizing more medical devices, which reduces the practicality of the device. A sterilization chamber of a small vacuum sterilizer solves the above disadvantages. Summary of the Invention

Therefore, this structural design can meet the needs of placing more medical devices in the device, thereby improving the practicality of the device.

[0015] 2. This application drives the first threaded rod to rotate through the output ends of the forward and reverse motors. The first threaded rod is threadedly connected to the moving rod. The two ends of the moving rod slide in the two long grooves respectively. The moving rod drives the two L-shaped columns to slide inside the two square tubes respectively, and the two L-shaped columns drive the warehouse door to move away from the warehouse body, so that multiple tray racks can be moved out of the warehouse body to facilitate personnel to take out medical devices from the tray racks.
