A kind of ozone sterilization device and method

Abstract

The invention discloses an ozone sterilization device which comprises a shell, an ozone generator, a control computer and a sterilization bag. The ozone sterilization device is characterized in that an attraction pipe and a suction pipe are arranged on the shell; the sterilization bag is used for storing to-be-sterilized articles; openings are formed in two ends of the sterilization bag; the opening in one end is communicated with an ozone pipe so as to introduce ozone into the sterilization bag; the opening in the other end is commutated with the suction pipe so as to exhaust the exhausted ozone gas. The method comprises the following steps of: (a) placing the to-be-sterilized articles; (b) connecting the pipes; (c) setting sterilization parameters and starting sterilization; (d) establishing a negative pressure environment; (e) introducing the ozone; (f) carrying out pressure detection; (g) carrying out sterilization time judgment; (h) carrying out ozone concentration judgment; and (i) evacuating the ozone. According to the device and the method, the problem that a large medical device cannot be effectively sterilized is solved; the ozone in the sterilization bag is maintained at relatively high concentration; the microorganisms on the articles can be thoroughly and permanently eliminated; no zone is released; the environmental pollution is avoided.

Description

Technical field [0001] The present invention relates to an ozone sterilization device and method, and more specifically, to an ozone sterilization device and method for non-disposable items used in hospital operating rooms or wards, and in particular to beds such as beds. Larger equipment that is difficult to sterilize. Background technique [0002] Ozone sterilization has been recognized by the world, as long as the concentration is high enough, it can kill all living things. Ozone has obvious inactivation effects on almost all germs, viruses, molds, fungi, protozoa, and oocysts, and the sterilization time is extremely fast, 300-600 times that of chlorine and 3000 times that of ultraviolet rays. [0003] In the use of hospital equipment, sterilization is an indispensable process. Whether it is surgical instruments, surgical equipment or disposable medical instruments, it cannot be used without sterilization. With the development of science and technology, there are more and more...

AI Technical Summary

Problems solved by technology

When using pure oxygen to supply the ozone generator, many problems will be encountered. If an oxygen cylinder is used to supply the ozone generator, the amount of oxygen is very large and it is difficult to supply it for a long time.

If using an oxygen concentrator to supply oxygen, it is bulky and cannot be used in the room

so that ozone sterilization cannot be used
