Abstract

The invention relates to a dustproof breathing machine. The dustproof breathing machine comprises a bottom plate, a supporting column, a main body, a filter screen and an air outlet pipe and further comprises a dustproof mechanism and a cleaning mechanism, wherein the dustproof mechanism comprises a dustproof box, a first bearing, a rotating shaft, a cover plate, a first magnet block, a second magnet block, a power rod, a disinfection assembly and two limiting assemblies; and the cleaning mechanism comprises a lead screw, a third bearing, a ball screw bearing, a second spring, a connecting shaft and two scraping rods. According to the dustproof breathing machine, the function of shielding the air outlet pipe is achieved through the dustproof mechanism, when the breathing machine is idle, external dust cannot fall on the air outlet pipe, and therefore the air outlet pipe cannot be polluted and cannot be blocked, the influence on oxygen supply work is prevented, the function of cleaning the filter screen is achieved through the cleaning mechanism, and dust is separated from the filter screen through rotation of the scraping rods, so that filter holes in the filter screen cannot be blocked by the dust, the influence on air circulation is avoided, and the practicability of the device is improved.

Description

technical field

[0001] The invention relates to the field of operating room medical instruments, in particular to a dust-proof ventilator. Background technique

[0002] Ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients.

[0003] Existing ventilators are usually equipped with a filter screen to remove impurities from the air entering the main body, so as to ensure the purity of the oxygen supply. After a long time of use, the filter holes on the filter screen are easily blocked by dust, which affects the quality of the air. Not only that, the outlet pipe of the existing ventilator has no shield, so that the dust in the air is easy to adhere to the outlet pipe and pollute the outlet pipe, and it is also easy to block the outlet pipe, thus affecting Oxygen supply work reduces the reliability of existing ventilators.
