Abstract
The utility model relates to an instrument applied to collect and sterilize the expiratory air of patient. An open face mask is arranged in the front of the patient head, keeping close to the face; a pipe, an expiratory filter and a disinfecting apparatus are communicated with the face mask, and a fan sucks the expiratory air through the pipe, the expiratory filter and the disinfecting apparatus; the lower part of the face mask is to be made as a subpressure district, with the difference of the barometric pressure, the expiratory air of patient is separated from the outside air and then induced into the pipe communicated with the face mask, the expiratory filter and the disinfecting apparatus sterilize the expiratory air which is then discharged outside from the discharge port of the fan. The subpressure at the lower part of the face mask is relative less, so that the breath of the patient is not affected; but the utility model can prevent the virus transmission caused by the expiratory air of patient or cough droplet; therefore, the utility model can protect the medical stuff during the fighting against SARS or other organule diseases.
Description
(1) technical field
This utility model relates to a kind of decontaminating apparatus of expired gas, refers in particular to a kind of patient expired shrinkage of QI collection decontaminating apparatus that carries out disinfection and discharge after the expired gas collection with the epidemic victim.
(2) background technology
Infectious respiratory disease (example: form when severe acute respiratory syndrome) Bing Du main route of transmission is by patient respiration, cough and speech.Patient breathe, aerosol suspension that expiration when cough and speech or the spittle form is in air, viruliferous microorganism is adsorbed in the aerosol particles surface, along with the mobile of air propagated, cause the propagation of communicate illness, and the frontline medical staff of treatment infectious respiratory disease suffers infected probability bigger.
In order to reduce respiratory infectious disease Human virus's route of transmission, at present, hospital is that employing purification filtering and reduction air pressure are the method that the room internal gas pressure is lower than outdoor air pressure (so-called negative pressure or purification ward) to respiratory infectious disease people's ward, it is outdoor that this type of ward can prevent that room air from flowing to, but, when the medical worker entered this ward, because of being in a negative pressuren zone together with patient, the virus that patient's the expiration and the spittle carry still can infectedly arrive.Therefore, how to solve to carry out disinfection after patient's expired gas collected and discharge rather than the problem of diffusion then and there is one of important behave of resisting infective virus such as " severe acute respiratory syndrome ".
(3) utility model content
The purpose of this utility model is that a kind of expired gas with the epidemic victim of design is extracted out and carried out disinfection after the collection and be discharged to outdoor a kind of patient expired shrinkage of QI collection decontaminating apparatus.
The purpose of this utility model is achieved in that
A kind of patient expired shrinkage of QI collection decontaminating apparatus, its feature comprises:
Face shield: be open structure;
Pipeline: be connected with described face shield;
Exhalation filter: be connected with described pipeline, described exhalation filter is made up of grade one filter at least, and every grade of filter is built-in with filter;
