Medical high-efficiency filter capable of realizing secondary sterilization

Abstract

The invention discloses a medical high-efficiency filter capable of realizing secondary sterilization. The medical high-efficiency filter comprises an air inlet assembly, a sterilization assembly anda cooling assembly, a filter screen and blades of the air inlet assembly are installed in a first cavity and a second cavity of a supporting shell respectively, an air inlet pipe is connected to the supporting shell, a motor is connected to the blades, and the motor is started to rotate the blades so as to suck in air which is preliminarily filtered through the filter screen; the sterilization assembly comprises a connecting pipe, a sterilization cavity, a nozzle and a steam generation device, the sterilization cavity is communicated with the supporting shell through the connecting pipe, the steam generation device is communicated with the nozzle, the nozzle is located in the sterilization cavity, and the steam generation device generates high-temperature steam, so that air from the connecting pipe is subjected to high-temperature sterilization; the cooling assembly comprises a spiral pipe, an air outlet pipe and a cooling box, the spiral pipe is communicated with the sterilization cavity, the cooling box is arranged on the outer side, cooling liquid is arranged in the cooling box and can cool air, finally clean and sterile air is exhausted through the air outlet pipe, and secondary pollution is avoided.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a medical high-efficiency filter capable of secondary sterilization. Background technique [0002] The air filter is a device that captures dust from the gas-solid two-phase flow through the action of porous filter materials and purifies the gas. It purifies the air with low dust content and sends it into the room to ensure the clean room process. Requirements and air cleanliness in general air-conditioned rooms, because hospitals are public places where people gather, so air filters are also widely used in hospitals. [0003] In the prior art, after the air filter is used, bacteria and dust will accumulate on the filter layer after being intercepted by the filter layer. At this time, the filter layer will become a breeding ground for bacteria growth. If things go on like this, the filtering effect of the air filter will be affected. have an impact, and these bacteria may also c...
