Abstract

The utility model relates to a separated respiratory machine for preventing SARS virus, which is an isolating virus protective cover for the respiration of a person. The utility model is characterized in that the utility model is a helmet-shaped closing transparent protective cover, one side of the utility model is provided with a respiration air inlet pipe which is communicated with fresh air outside via a communicating hose, and the other side of the utility model is provided with an exhalation air outlet pipe which is communicated with a small noxious air processing cylinder via a communicating hose; one end of the exhalation air outlet pipe in the protective cover is provided with a mouth-exhaling air exhaust head, and the other end of the exhalation air outlet pipe is provided with a non-return air exhaust valve; the mouth-exhaling air exhaust head is a soft elastic opening in the shape of a nipple of a baby, and the non-return air exhaust valve is composed of a conical pipe of which the small end faces inward, and a movable ball which is arranged in the conical pipe; an opening end on the lower part of the protective cover is shrunken inwards, and the opening end is provided with an elastic telescopic mouth ring. The utility model has the advantages that the infection of the SARS virus through respiratory tracts can be effectively prevented; the utility model is particularly suitable for medical care personnel which have intimate contact with an SARS patient; the structure is simple and the cost is low.

Description

Anti-SARS virus is isolated respiratory organ

Technical field: this utility model relates to a kind of medical appliance, and particularly anti-SARS virus is isolated respiratory organ

Background technology: present SARS virus serious harm health, and one of main route of transmission of SARS virus is aerial infection, therefore for the medical personnel who contacts closely with the SARS patient, how to prevent effectively that from respiratory tract infection SARS virus be a problem that crucial urgency is to be solved.

Summary of the invention: the purpose of this utility model is to providing a kind of utensil that can prevent to infect from respiratory tract SARS virus effectively with personnel that the SARS patient contacts closely.

Technical solution of the present utility model is that a kind of anti-SARS virus is isolated respiratory organ, being one supplies the people to breathe the virus-isolating protective cover of usefulness, it is a transparent protective cover of helmet-like sealing, one side has the breathing air inlet pipe, be communicated with extraneous fresh air through being communicated with flexible pipe, opposite side has the expiration discharge pipe, through being communicated with soft pipe connection to small fulsome air processing system; The end of expiration discharge pipe in protective cover chewed and exhaled exhaust head, the other end that the check air bleeding valve is arranged, and chewing and exhaling aerofluxus is that the resilient flexible that a baby milk is chewed shape is chewed, and the check air bleeding valve is a movable bulb stopper to be set in one section small end Taper Pipe inwardly constitute; The lower open end of protective cover inwardly shrinks, and is provided with the seal mouth ring of elastic telescopic.

Fig. 1 is that anti-SARS virus is isolated the respiratory organ structure sketch map.

Fig. 2 is a fresh air chamber sketch map.

Fig. 3 is fresh air chamber and ward connection diagram.

The specific embodiment:

This utility model further specifies as follows in conjunction with specific embodiments referring to accompanying drawing:

A kind of anti-SARS virus is isolated respiratory organ, being one supplies the people to breathe the protective cover of the isolation SARS virus of usefulness, referring to accompanying drawing 1, it is a transparent protective cover [5] of helmet-like sealing, one side has breathing air inlet pipe [2], be communicated with extraneous fresh air through being communicated with flexible pipe [1], opposite side has expiration discharge pipe [7], is communicated to the oxious gas processing system through being communicated with flexible pipe [10]; The end of expiration discharge pipe [7] in protective cover [5] chewed and exhaled exhaust head [6], the other end has the check air bleeding valve, chewing and exhaling exhaust head [6] is that the resilient flexible that a baby milk is chewed shape is chewed, and the check air bleeding valve is to constitute by a movable balls cold [9] is set in one section small end Taper Pipe [8] inwardly; The lower open end [11] of protective cover [5] inwardly shrinks, and contraction mouth is provided with the seal mouth ring [12] of elastic telescopic.Protective cover [5] connects the extraneous fresh air that is communicated with and can be provided by special fresh air chamber [16] through connecting flexible pipe [1], ginseng accompanying drawing 2, and there is awning [14] on fresh air chamber [16] top, air inlet [15], indoor have a ultraviolet germicidal lamp [17].The protective cover that personnel use among each ward A, B, C, D, the E is attached to inlet manifold [18] through making up flexible pipe [1], and inlet manifold [18] connects with bottom, fresh air chamber [16] and is communicated with.Referring to accompanying drawing 3.Protective cover [5] connects with exhaust main through exhaust hose [10] and is communicated with, and exhaust main is connected to special air disinfection sterilization chamber.Protective cover [1] inner top is equipped with soft support, and soft support is a support ring [4] that some support belts [3] are arranged, and support belt [3] end is connected in protective cover [1] top.

Using method of the present utility model is that protective cover [1] is worn in head, cervical region is tight through resilient flexible seal mouth ring [12] sealing, milk is chewed chewing of shape exhales exhaust head [6] to keep in the mouth, when air-breathing, tongue withstands chews the nipple aperture of exhaling exhaust head [6], with the oral cavity waste gas of bragging from the nipple aperture, realize isolating and breathe with anti-cover [1] air outside.

The advantage that the anti-SARS virus of this utility model is isolated respiratory organ is to prevent effectively that SARS virus infects from respiratory tract, and being particularly suitable for has the close medical personnel that contact to use with the SARS patient.And it is simple in structure, cheap.

Claims

1, a kind of anti-SARS virus is isolated respiratory organ, it is an anti-defensive army of virus-isolating of breathing usefulness for the people, it is characterized in that it is a transparent protective cover of helmet-like sealing, one side has the breathing air inlet pipe, be communicated with extraneous fresh air through being communicated with flexible pipe, opposite side has the expiration discharge pipe, through being communicated with soft pipe connection to small fulsome air processing system; The end of expiration discharge pipe in protective cover chewed and exhaled exhaust head, the other end that the check air bleeding valve is arranged, and chewing and exhaling exhaust head is that the resilient flexible that a baby milk is chewed shape is chewed, and the check air bleeding valve is a movable bulb stopper to be set in one section small end Taper Pipe inwardly constitute; The lower open end of protective cover inwardly shrinks, and is provided with the seal mouth ring of elastic telescopic.
