Cabinet door for hydrogen peroxide low-temperature plasma sterilizer

Abstract

The invention discloses a cabinet door of a hydrogen peroxide low-temperature plasma sterilizer, which comprises a door body (1), an observation window (2) and a casing (3). A lookout hole (A) is opened at the position, and a circular groove (D) is opened on the back of the housing (3) and a boss (E) is arranged in the groove, and it is installed in the circular groove (D) There is a light-shielding sheet (4) with two gaps, and a pick hole (B) is opened on the housing (3) corresponding to the position of the light-shielding sheet, and the light-shielding sheet (4) is rotated through the pick hole outside the cabinet door , the first notch on the shading sheet (4) will be rotated to the position of the lookout hole on the casing, and the working conditions in the equipment sterilization chamber can be observed through the observation window. After the observation is completed, rotate the shading sheet (4) in the opposite direction, and The light-shielding part under the second notch on the sheet is rotated to the position of the observation hole, thereby completely covering the observation window and preventing light and heat in the sterilization chamber from being lost through the observation window.

Description

technical field [0001] The invention relates to a cabinet door of disinfection and sterilization equipment, in particular to a cabinet door of hydrogen peroxide low-temperature plasma sterilization equipment with an observation window, and belongs to the technical field of disinfection and sterilization equipment. Background technique [0002] In the medical field, the disinfection and sterilization of medical devices is particularly important. The sterilization methods are generally divided into high temperature and low temperature. The low temperature sterilization method is mainly suitable for medical devices that are sensitive to heat or humidity. Sterilant-assisted, which belongs to the chemical sterilization method, the mainstream method is to vacuum vaporize chemical sterilants such as hydrogen peroxide, ethylene oxide or formaldehyde at a temperature lower than 80°C, and use the vaporized steam to Medical equipment is sterilized. Among these three chemical sterilants...

Problems solved by technology

[0003] However, in practice, it was found that the above-mentioned method of directly opening a glass window on the cabinet door will cause part of the energy in the sterilization chamber to be lost through the window, that is, the heat of the hydrogen peroxide vaporized after heating up will be dissipated partly through the window. part, which affects the complete vaporization of hydrogen peroxide, and at the same time, the light energy in the process of hydrogen peroxide being excited into plasma by electric energy in the sterilization chamber will also scatter part of it through the window, that is, the opening of the window affects The normal operation of hydrogen peroxide low-temperature plasma sterilization equipment will reduce the sterilization performance of the equipment, and the plasma light continuously scattered through the window will also cause light pollution to the sterilization room
