Medical pressure gauge and indicator device

摘要: The medical pressure gauge and indicator device is for diagnosing the presence of tension pneumothorax in pleural cavity a patient. comprises diaphragm, needle sleeve, with diaphragm having an interior surface contact pressurized air within exterior atmospheric air. sufficient length puncturing chest wall extending into cavity. sleeve form elongated rigid tubular body, provided pair ends mounts at opposite thereof. has expanded position collapsed position. When position, generally located sleeve. rear end inflow communication sharpened wall-puncturing forward end. With such construction, adapted to transmit where it acts upon whereby, if greater than present, will be urged out or assume balloon-like shape configuration which positively indicates cavity, thus indicating person treatment required If does not expand, less exits another
