An inflatable face seal () for a respiratory mask, the inflatable face seal comprising an annular air-tight hollow portion () where a cross section through one section of the annular hollow portion () comprises a bonded joint () which joins two overlapping flanges (). The two flanges are bonded together such that an inwardly facing surface () of a first flange () of the two overlapping flanges is in contact with an outwardly facing surface () of a second flange () of the two overlapping flanges. In this way, the bond is strong and only exposed to shear stresses when the annular air-tight hollow portion is exposed to increased pressure.

Inflatable face seal for a respiratory mask and method of producing same

A disposable manometer for use with a breathing system for monitoring a patient during positive pressure ventilation. The disposable manometer includes a housing with an upper and lower portion, a moving member and a flexible rolling diaphragm sealing mechanism between the moving member and the upper portion of the housing. A calibrated tension means resists movement of the moving member and provides accurate measurement of the ventilation pressure.

Disposable manometer for use with patient breathing systems

A portable suction pump for life-saving purposes and normally driven by compressed gas. The pump includes a pump assembly having a suction chamber with an outlet leading to the ambient atmosphere and an inlet communicating with a secretion-receiving reservoir with attached tubing permitting suction of secretion, primarily from the air ducts of an unconscious patient. The pump is characterized by the pump assembly having a housing enclosing the suction chamber and closed at one end by a first annular diaphragm and, centrally sealingly attached thereto, a rigid body guided for movement relative to the housing and having wall portions defining, together with part of the housing, a motor chamber delimited from the suction chamber by a second annular diaphragm. The motor chamber communicates with a driving gas supply and exhaust connections and a valve arrangement for the intake and exhaust of compressed driving gas.

Tracheal suction pump designed primarily for aspiration purposes

An attachment device for use in a tracheal aspirator comprising a hand-held container with rigid walls having a secretion inlet opening with an inside diameter sufficiently large to permit passage of solid particles and an outlet opening for connection to the suction tube of a pump. The device further comprises a secretion suction tube of correspondingly large inside diameter and a length just sufficient to enable the device to be operated in front of the mouth of the patient. One end of the suction tube is received by the secretion inlet opening of the container. The inside diameters of the secretion inlet opening and suction tube are between 6 and 12 millimeters and the length of the suction tube is in the range between 200 and 300 millimeters.
