Abstract
The utility model discloses an exhaled-air collecting/filtering mask for patients with infectious diseases. The exhaled-air collecting/filtering mask comprises an arched mask body, an air delivery tube, a forced ventilation mechanism, and an air filtering device, wherein the air delivery tube is communicated with the arched mask body; the forced ventilation mechanism and the air filtering device are both arranged on the air delivery tube. Since the probability of a normal person being infected by infectious diseases has direct relation with received quantity of pathogens, the normal person will be infected if the quantity of pathogens received by him is larger than a critical value, and the normal person will be not infected when the quantity of pathogens received by him is within two critical values, and infected probability is proportional to the received quantity of pathogens. The utility model is invented based on this mechanism. The utility model has simple structure, and easiness in operation. Furthermore, the utility model will not bring mental pressure to the patients, and is particularly suitable for use at infectious disease wards.
Description
Technical field
The utility model relates to a kind of gas and collects filter mantle, and particularly a kind of patients with infectious diseases breath is collected filter mantle.
Background technology
Although everybody knows that air is one of main media of infectious disease transmission, but, at present general patients with infectious diseases all is in the nearly open environment fully, like this can pathophorous pathogen concentration in patient's surrounding air just very high, medical personnel or visiting personnel during near the patient infected probability also just very high.In order to reduce infected probability, the measure that medical personnel mainly take is worn and is isolated that clothes wear masks etc., isolate clothes and mouth mask outside like this and can have the pathogen that can infect inevitably, when medical personnel take off the isolation clothes or pluck mouth mask, also can be by pathogenic infection.
The utility model content
In order to reduce of the pollution of patients with infectious diseases institute breath to its surrounding environment, reduce the concentration of infectious disease pathogens in the air, the purpose of this utility model provides a kind ofly can effectively collect patients with infectious diseases institute breath, it is carried out after the filtration treatment patients with infectious diseases breath of discharging again collect filter mantle.
For realizing the purpose of this utility model, this patients with infectious diseases breath is collected filter mantle and is comprised arc cover body, gas transmission pipeline, forced ventilation mechanism, air filter, gas transmission pipeline is communicated with the arc cover body, and forced ventilation mechanism and air filter are installed on the gas transfer pipeline.
Further, described arc cover body is made by lucite or other transparent material, and described gas transmission pipeline is made by flexible pipe, and described forced ventilation mechanism is air pump or fan.
Further, described air filter is the air-filtering sterilizing machine, and this air-filtering sterilizing machine is arranged on the gas transfer pipeline of described forced ventilation mechanism upstream.
Further, described air filter is arranged on the gas downstream transfer pipeline of described forced ventilation mechanism.
During use, the arc cover body is placed appropriate position, patients with infectious diseases dead ahead, start in the gas suction arc cover body of fan with patient's exhalation, the gas that is inhaled into is discharged through pipeline, air filter again.Because just discharging after the gas that patients with infectious diseases is breathed out is disinfected through filtration, thereby can effectively reduce the quantity of infectious disease pathogens in patient's surrounding air, the arc cover body also has the isolated screen wind action simultaneously, the splash that stops when the patient coughs to be sprayed reaches the purpose that reduces the infectious disease transmission probability thus.Because of the infected sick probability that infects of normal person and the pathogen quantity of its acceptance have direct relation, the pathogen quantity of accepting as the normal person is during greater than a certain critical value, must be infected, and the pathogen quantity of accepting as the normal person is during less than a certain critical value, then can be not infected, the pathogen quantity of accepting as the normal person is between two critical values the time, and infected probability is directly proportional with the pathogen quantity of its acceptance.The utility model reduces the infected probability of normal person by the quantity of control pathogen.The utility model not only structure is simple especially, easy to use, and can not bring additional psychological pressure to the patient, is particularly suitable for using in places such as lazaretto wards.
Description of drawings
Accompanying drawing is the utility model structure and user mode schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in drawings, the utility model comprises arc cover body 1, gas transmission pipeline 2, air-filtering sterilizing machine 3, exhaust fan 4, and air-filtering sterilizing machine 3 is positioned at the downstream of exhaust fan 4.Air to be sterilized is sucked from arc cover body 1, and discharges from the caudal end egress 5 of exhaust fan 4.
During use, the utility model is fixing by support 8 supportings, and patient 6 lies on the bed 7, arc cover body 1 is placed patient 6 above-head.Start exhaust fan 4, air is inhaled in the arc cover body 1 along the arrow A direction, the air that is inhaled into passes to air-filtering sterilizing machine 4 through conveyance conduit 2, discharges from air outlet 5 through filtering the sterilization back, and airborne pathogen is filtered and killed by the air-filtering sterilizing machine.
After the gas that patients with infectious diseases is breathed out passes through from the utility model, wherein contained pathogen is effectively filtered to be killed, avoided the aerial diffusion of pathogen, not only can provide the working environment of a safety, and help preventing that the patient is repeated to infect for medical care or other healthy population.
Adopt light transmissive material making arc cover bodies such as lucite, can reduce the psychological pressure that the patient is caused.Gas transmission pipeline adopts flexible pipe for medical purpose, and diameter is between 5 to 200 centimetres.
Claims (4)
