Apparatus for mechanically ventilating a patient
First Claim
1. Apparatus for mechanically ventilating a patient, comprisingtwo separate, substantially rigid components structured and arranged to be coupled to both simultaneously move and move towards and away from one another and one of said rigid components positioned adjacent a front or anterior of a torso of the patient and the other of said rigid components positioned adjacent a rear or posterior of the torso of the patient, on opposite sides of the torso of the patient, anda flexible, air-tight, elastic covering encapsulating both said components on all sides thereof and surrounding the torso when placed about the torso of the patient,such that when said components move away from one another within said air-tight, elastic covering, negative pressure is generated within said air-tight, elastic covering and influences the torso to cause the patient to draw air into the patient'"'"'s lungs, andwhen said components no longer move away from one another, the patient'"'"'s natural pulmonary elastic recoil expels the air from within the patient'"'"'s lungs and, together with said air-tight, elastic covering returning to unstretched condition, causes the pressure within said air-tight, elastic covering to become positive and move said components together.

Abstract
An apparatus for mechanically ventilating a patient is provided to have two separate components movably arranged with respect to one another within a flexible, air-tight covering fit about the torso of a patient. When the components move away from one another within the air-tight covering, negative pressure is generated which causes the patient to draw air into the lungs. Conversely, when the components stop moving away from one another within the air-tight covering, the patient'"'"'s natural exhalation recoil takes over to allow the patient to expel the air from within the patient'"'"'s lungs.

11. An apparatus for mechanically ventilating a patient, comprising
two separate, substantially rigid components structured and arranged to be movably coupled with respect to one another, a flexible, air-tight, elastic covering structured and arranged to cover both said components when placed about a torso of the patient, and means for movably coupling said components together, wherein said components are movably coupled to each other to reciprocally move towards and away from one another, and said means are a pantograph linkage coupling said two components together, such that when said components move away from one another within said air-tight, elastic covering, negative pressure is generated within said air-tight, elastic covering and influences the torso to cause the patient to draw air into the patient'"'"'s lungs, and when said components no longer move away from one another, the patient'"'"'s natural pulmonary elastic recoil expels the air from within the patient'"'"'s lungs and, together with said air-tight, elastic covering returning to unstretched condition, causes the pressure within said air-tight, elastic covering to become positive and move said components together.
