Breathing filter

Abstract

The invention provides a breathing filter which comprises a front cover and a back cover connected to each other. An electrostatic filter membrane is arranged between the front cover and the back cover. The front cover is provided with a plurality of first air guide vanes which are uniformly arranged in a vortex manner. The back cover is provided with a plurality of second air guide vanes which are uniformly arranged in a vortex manner. When the front cover and the back cover are connected, the vortex directions of the first air guide vanes and the second air guide vanes are same. The first air guide vanes and the second air guide vanes guide air blown into the filter, so that part of gas centralized at the center of the electrostatic filter membrane is diverged to the periphery of the electrostatic filter membrane, and therefore the whole electrostatic filter membrane plays a filtering role to solve the problem that the utilization ratio of the electrostatic filter membrane in a conventional breathing filter is not high.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a breathing filter. Background technique [0002] The breathing filter is a filter used in the breathing circuit, which has the functions of different degrees of biological filtration heating and reducing the generation of net raw water, prevents the collapse of small airways and atelectasis, and can reduce the risk of microorganisms in the breathing circuit. Pollution, reduce hospital pollution. Breathing filters generally include a front cover and a back cover, and an electrostatic filter membrane is clamped between the front cover and the back cover to isolate germs; in conventional breathing filters, germs are concentrated in the middle of the filter membrane, and the utilization rate is not high. High, poor adsorption. Contents of the invention [0003] The technical problem to be solved by the invention is to solve the technical problem that the utilization rate...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to solve the technical problem that the utilization rate of the electrostatic filter membrane in the traditional breathing filter is not high

[0005] The first air guide vane and the second air guide vane guide the air blown into the filter, so that part of the gas concentrated in the center of the electrostatic filter membrane will diverge to the periphery of the electrostatic filter membrane, so that the entire electrostatic filter membrane can play a role. Filtration effect, which solves the problem of low utilization rate of electrostatic filter membrane in traditional breathing filters
