Abstract
A chest enclosure apparatus is disclosed for use in producing an assisted ventilation of the lungs of a patient when combined with an air oscillator. The chest enclosure includes a chest covering tunnel member made of a stiff, but flexible material. Additionally, a wall member is included at each end of the tunnel member, with each wall member having a concave radially inner periphery for sealing against the front surface of patient's body and being made of an air-impermeable, flexible cushioning material. A band of a flexible, air-impermeable material is provided and extends from each of the longitudinally running edges of the tunnel member for wrapping in a mutually overlapping around the chest region of a patient's back. A fastener is provided for fastening one of the band in order to hold the bands in the overlapping relationship. Finally, an air passageway is provided for the enclosure in order to allow for a connection to a conventional air oscillator.
