Problems solved by technology

[0008] The above-mentioned disinfection and sterilization device uses the evaporator to heat and vaporize the hydrogen peroxide sterilizing liquid sent in at high temperature, and then sends it into the sterilization chamber. In this way, the atomization is uneven and the atomization speed is slow. The diffusion effect in the interior is not very good, and there is also the risk of decomposing the sterilization solution at high temperature
In addition, similar products currently on the market also use ultrasonic atomization and other similar feeding devices. The structure of this feeding device is relatively complicated, and additional circuit support is required.
Both of the above methods increase the cost of the product itself and the unstable factors in the atomization process

Embodiment 1

[0026] see figure 1 , Embodiment 1 of the low-temperature plasma disinfection and sterilization equipment of the present invention includes the following parts: a cylindrical sterilization chamber 1, the left end of which is closed, and the right end is provided with a place for putting and taking articles to be sterilized, and can Vacuum-sealed airtight door 2, the peripheral surface of sterilization chamber 1 is provided with an electric heating film capable of temperature control. The shape of the sterilization chamber 1 can also be designed into shapes such as a sphere or a rectangle according to specific conditions and actual needs, and its bulkhead material is generally selected from stainless steel, and other alloy materials can also be selected.

[0027] The top of the sterilization chamber 1 has a material inlet 3, and the bottom has a vacuum port, which is connected to a vacuum pump 5 through a vacuum pipeline 4, and a vacuum valve 6 is provided on the vacuum pipelin...

Embodiment 2

[0034] see figure 2 , the basic composition of the second embodiment of the low-temperature plasma disinfection and sterilization equipment of the present invention is similar to that of the first embodiment, and the same reference numerals are used for the same components for easy understanding. The main difference between this embodiment and the first embodiment lies in the number and arrangement of the micropores of the microporous atomizing nozzle 16 and the position of the microporous atomizing nozzle 16 . In this embodiment, the microporous atomizing nozzle 16 and the feed port 3 are also connected by a buffer pipe 17 to prevent the atomized sterilizing liquid from directly impacting the sterilized items and causing damage.

[0035] see Figure 5 and Image 6 The general structure of the microporous atomizing nozzle 16 is the same as that of the microporous atomizing nozzle 12 in the first embodiment, the difference is that there are four circular microporous nozzles ...

Abstract

The invention discloses a low-temperature plasma sterilization device, which comprises a sterilization chamber, a liquid container and a micro-porous atomization nozzle. The sterilization chamber is provided with a feed port and is connected with a vacuum extractor; the liquid container is filled with sterilization solution and is communicated with the feed port; and the micro-porous atomization nozzle which is controlled by a valve mechanism is arranged between the liquid container and the feed port. Since the micro-porous atomization nozzle is adopted for atomization of the sterilization solution at the low temperature and transmission of the sterilization solution into the sterilization chamber after atomization, the invention has the advantages of simple structure and convenient use, and avoids the risk of decomposition of the sterilization solution at the high temperature. The sterilization solution can be atomized uniformly and rapidly, and the diffusion effect of the atomized sterilization solution in the sterilization chamber is good, thereby not only reducing the cost, but also improving the reliability and safety. The invention can not only be applied in the sterilization of medical apparatuses, but also can be applied in industries or places needing sterilization such as utensils and the like.

Description

technical field [0001] The invention relates to a disinfection and sterilization equipment, in particular to a low-temperature plasma disinfection and sterilization equipment. Background technique [0002] Various methods of disinfection and sterilization have been used to disinfect and sterilize different kinds of disposable or reusable medical devices. Among these methods, a method of sterilizing and sterilizing using steam or dry heating has been widely used. However, this method of disinfection and sterilization cannot be used to sterilize substances that are adversely affected by such heating or steaming. [0003] The material properties and structural characteristics of endoscopes such as oral mirrors, gastroscopes, colonoscopes, intraocular lenses, and some medical diagnostic instruments such as rubber and plastic tubes make their sterilization neither traditional high-temperature and high-pressure methods, nor simple. By irradiation or chemical methods. Cross-infe...
