Abstract

The utility model discloses an expired gars filtrating style sterilizing respirator, which consists of a mask, an inspiration valve, a spare oxygen supplying interface, an exhaling valve, a sterilizing filter material etc. The utility model arranges the inspiration valve in a colored rubber mask or a transparent silica gel mask; the inspiration valve has a connecting respirometer or the interface of a respirometer oxygen supplying interface; the exhaling valve is arranged below the lower part of the mask which is spirally connected to a poison filtering box; the poison filtering box has a filter material fixing case, thus the filter material fixes a bubble membrane mat, the sterilizing filter material and an outer layer filter material fixing bubble membrane mat; the poison filtering box is tightly spanned and sealed by a box lid, the two ends of which is sealed through a sealing layer to spare use; and the mask has an elasticity adjustable fixing belt. The utility model has advantages that: able to kill pathogens such as virus, bacteria, good respirator sealing performance and the respirator is reused when be disinfected.

Description

Expiratory air filtering type antiseptic face mask

Technical field the utility model relates to antiseptic face mask, particularly the mouth mask that can carry out disinfection to patient expired gas.

Background technology first half of the year in 2003, the SARS virus of have swepting the globe has seized a lot of people's life in the very short time, and the medical personnel who particularly is engaged in rescue work accounts for many ratios.Its basic reason is because this virus mainly is to propagate by respiratory tract, and the virus in the patient expired gas is not effectively sterilized, and causes healthy people to be infected.Except SARS virus, the disease that infects by respiratory tract also has viruses such as influenza virus, measles, mumps, varicella, in addition bacterial pathogens such as the diplococcus meningitidis of epidemic meningitis, corynebacterium diphtheriae, Bordetella pertussis, pulmonary bacillus.Present cotton yarn mouth mask plays effective filtration filtration and disinfective action even the thickening number of plies is also difficult to patient expired gas.

The summary of the invention the purpose of this utility model provides in order to overcome above-mentioned weak point of the prior art that a kind of expiratory air carries out disinfection to patients with infectious diseases just, cuts off the antiseptic face mask of respiratory infectious approach.

The design's structure is to be provided with inlet valve on the oronasal mask of common colored rubber or transparent silicon rubber, have the interface that connects respirator or lung ventilator Oxygen tube on the inlet valve, be provided with outlet valve in the oronasal mask bottom, what be connected with the outlet valve bottom is a malicious box of filter, filters and is provided with the filtrate fixed grating in the malicious box in turn, filtrate is the vacuolar membrane pad fixedly, light weight, moisture absorption, sterilization filtrate, outer filtrate is the vacuolar membrane pad fixedly, filters malicious box and is screwed by lid, filter malicious box when not using, two ends are standby by the sealant sealing.Also be provided with the fixed band that to regulate degree of tightness on the oronasal mask.On the oronasal mask of common colored rubber or transparent silicon rubber, also be provided with the thin oxygen input tube spare interface of with closure.

The advantage that the utility model compared with prior art has is: filtration and kill virus, bacterial pathogens.In patient's the expiratory air period, promptly effectively cut off the respiratory infectious approach.Can sterilize after oronasal mask is used re-uses, and disinfection box uses the back replaceable.The mouth mask good airproof performance, virus, bacterium are difficult to slip through the net.The design has three kinds of functions: (1) can be done the expiratory air sterilization and use; (2) can do the expiratory air sterilization and add oxygen therapy usefulness; (3) can cure by oxygen therapy mouth mask with (take down filter malicious box).

Specific embodiment the utility model is described in further detail below with reference to accompanying drawing:

1. 1 kinds of expiratory air filtering types of embodiment antiseptic face mask, referring to accompanying drawing 1～7,9, on the oronasal mask (1) of common colored rubber or transparent silicon rubber, be provided with inlet valve (2), have the interface (3) of the Oxygen tube that connects respirator or lung ventilator on the inlet valve, be provided with outlet valve (4) in the oronasal mask bottom, what be connected with the outlet valve bottom is a filter malicious box (5), filter and be provided with filtrate fixed grating (6) in the malicious box in turn, filtrate is vacuolar membrane pad (7) fixedly, light weight, moisture absorption, sterilization filtrate (8), outer the filtrate fixedly malicious box of vacuolar membrane pad (9) filter are screwed by lid (10), filter malicious box when not using, two ends are standby by sealant (11) sealing.Also be provided with the fixed band (12) that to regulate degree of tightness on the oronasal mask.On the oronasal mask (1) of common colored rubber or transparent silicon rubber, also be provided with the thin oxygen input tube spare interface (13) of with closure.

The filter poison material of being adorned in the malicious box of filter has light weight, moisture absorption, non-toxic materials such as activated carbon, vacuolar membrane, silica gel, also is added with the disinfectant preparation to human respiratory safety of doses in material.Mouth mask is placed on dry shady and cool place and preserves when not using.

2. 1 kinds of expiratory air filtering types of embodiment antiseptic face mask, referring to accompanying drawing 1～6 and 8, its structure is substantially the same manner as Example 1, is the central authorities of the inlet valve (2) of thin oxygen input tube spare interface (13) oronasal mask (1) that is located at common colored rubber or transparent silicon rubber.
