ABSTRACT:
A lightweight molded-thermoplastic housing having flexible walls provides a respirator cavity having an internal volume adapted to accept either the torso of an adult patient or the body of a child patient. The molded-thermoplastic housing includes a thermoplastic cover member having integral walls that is removably fastened by spring-loaded latches in air-tight sealing engagement to an integral thermoplastic base member. The integral thermoplastic cover member has an open rectangular bottom having a comparatively large area, a vertically-spaced planar top having a comparatively smaller area, four vertically inclined arcuate support ribs individually extending from the vertices of the open bottom to corresponding confronting vertices of the planar top, and four sloping flexible planar walls that join the open bottom to the planar top between adjacent ribs. The base member includes four upstanding sidewalls defining a conformal mattress receiving cavity. A neck receiving opening is provided on one end of the respirator. A waist/leg receiving opening is provided on the other end of the respirator. An elongated and flexible neck receiving adjustable collar is removably attached to the neck receiving opening for providing an air-tight seal between the neck of a patient and the respirator. An elongated and flexible girdle having left and right leg receiving adjustable collars is removably attached to the waist/leg receiving opening to provide an air-tight seal between the legs of the patient and the respirator. An air-tight patient access hatch is provided. An oscillating pressure pump is provided for controllably varying the cavity pressure thereby to respirate a patient.
