Proposed is a diagnostic apparatus including: an anteroom having a first door; a specimen obtainment room having a second door to be closed while the first door is opened after a person designated to be diagnosed enters the anteroom, and a specimen obtainment space where a specimen is obtained from the person; a diagnosis room being kept secluded from an atmosphere of each of the anteroom and the specimen obtainment room; and a negative pressure generator providing a negative pressure in such a manner that pressure in the anteroom is formed above pressure in the specimen obtainment room, wherein a specimen obtainment means for obtaining the specimen from the person in the specimen obtainment room is installed in a direction from the diagnosis room toward the specimen obtainment room, and the specimen obtainment means is sealed from the atmosphere of the specimen obtainment room.

Provided is a clean booth in an assembled state, including: a frame; a wall portion that is provided on the frame and forms an internal space; a first unit that is provided on the wall portion and includes a first fan that supplies air to the internal space via a first filter; and a second unit that is provided on the wall portion and includes a second fan that exhausts the air in the internal space.

An airway management isolation enclosure and a method for protecting medical personnel from infectious agents when treating a patient having an infectious disease, comprising: (a) a frame that is positioned over the head and anterior thoracic region of the patient; (b) a transparent barrier supported by frame, which covers and forms a seal around the head and anterior thoracic region of the patient and allows medical personnel to create sealable entry ports; and (c) an air flow entry and a vacuum exit connection to direct the infectious agents in the form of respiratory droplets and particles produced by the patient to flow away from the head of the patient and out of the transparent covering while the medical personnel manages the airway and upper aerodigestive tract of the patient.

A biocontainment assembly for use with a patient suspected of having or diagnosed with a transmissible disease(s) capable of respiratory, airborne, contact, or droplet transmission includes a housing configured to be positioned over and at least partially enclose a head, neck, and/or torso of the patient. A sidewall of the housing includes an open portion contiguous with an at least partially pen bottom portion of the housing, sized to fit over at least a portion of the head, neck, and/or a torso of the patient. The housing also includes an airflow opening for evacuating fluid from an interior defined by the housing. The assembly also includes a drape configured to extend across the open portion of the sidewall having a first portion removably connected to the housing and an opposing second portion configured to be draped over the torso, abdomen, waist, and/or legs of the patient.

The present invention discloses a vertical soft U-shaped opening and closing sealed air-pressure chamber, comprising a chamber body and an outer zipper strip. The outer zipper strip is a U-shaped structure and installed in a front-end surface of a chamber door. A U-shaped sealing strip is arranged in a middle position between an inner zipper slider and an outer zipper slider. The chamber body is sealed in a U-shaped way, which can be adapted to various soft air pressure chambers. Whether a human body or the human body carried in a wheelchair or a cart is very convenient to enter the chamber body.

The present invention provides a negative-pressure shield device with a simple device structure, which is relatively inexpensive to manufacture, and is extremely effective in preventing infection within an ambulance. The negative-pressure shield device comprises a shield main body that is installed in a patient compartment of an ambulance, includes a ceiling part and a peripheral wall part, and covers at least the head of a patient on a stretcher mounted in the patient compartment, and a connection part which communicates with the interior of the shield main body and connects to a ventilation opening provided in the patient compartment.

A patient transport shield provides for a flexible support sheet supporting a patient with upstanding ribs holding a transparent cover over the patient to provide a patient volume that may hold negative pressure when the transparent cover is attached to the support sheet by a resealable pressure-sensitive attachment strip allowing rapid assembly and ready access to the patient.

A hypoxia recovery system capable of supplying breathing air with approximately 20% oxygen to a subject inside a mask off hypoxia training room without the use of a real world MD-1 aviator oxygen regulator, yet have the experience and realism of a real world MD-1 aviator oxygen regulator. The invention also teaches a method of hypoxia flight training, using said hypoxia recovery system.

A negative-pressure dome includes a transparent domed shield, a flexible skirt attached to the perimeter of the domed shield, a hose attachment port formed on the domed shield; and access openings in at least one of the domed shield and the flexible skirt. The transparent domed shield consists of a clear rigid plastic. The access openings may be at least partially occluded by flexible flaps that are deflectable to increase an open cross-section of the access openings. In a first configuration, the access openings are disposed in the domed shield sized to cover a face and are sized to have a cross-section between 3 cm.sup.2 and 200 cm.sup.2. In a second configuration, the access openings are disposed in the flexible skirt and are sized to have a cross-section between 30 cm.sup.2 and 200 cm.sup.2, while the domed shield is sized to cover head and chest of a subject.

There is disclosed a method and system for determining the partial pressure of at least one gas in a mixture of gasses contained in a pressure vessel, the mixture being pressurised to a level which is above local atmospheric pressure. The method comprises the steps of positioning a gas analysis sensor (14) within a pressure vessel (10); exposing the sensor to the mixture of gasses at the pressure level found in the pressure vessel; operating the sensor to measure the actual partial pressure of the at least one gas in the mixture contained in the vessel; and periodically calibrating the sensor by directing a calibrating gas mixture (20, 22) to the sensor in the chamber, the calibrating gas mixture being breathable by a human being.
