Respiration control apparatus
First Claim
1. An apparatus for controlling the respiration of a controlled body, comprising:
- a first circuit having an end connected to said controlled body and an opposite end connected to the outside of the apparatus;
a first check valve disposed in said first circuit for allowing said controlled body to inhale from said outside through said first circuit and preventing exhaled air from said controlled body from flowing into said first circuit;
a first solenoid-operated valve disposed in said first circuit for selectively connecting and disconnecting a respiratory system of said controlled body to and from said outside;
a second circuit having an end connected to said controlled body and an opposite end connected to said outside;
a second check valve disposed in said second circuit for allowing said controlled body to exhale to the outside through said second circuit and preventing said controlled body from inhaling through said second circuit;
a second solenoid-operated valve disposed in said second circuit for selectively connecting and disconnecting the respiratory system of said controlled body to and from said outside; and
a controller for controlling said first solenoid-operated valve and said second solenoid-operated valve at a predetermined time in a respiratory cycle thereby to disconnect the respiratory system of said controlled body from said outside, and controlling said first solenoid-operated valve and said second solenoid-operated valve after elapse of a predetermined period from said predetermined time thereby to connect the respiratory system of said controlled body to said outside.

Abstract
A respiration control apparatus connected to a controlled body includes a respiration circuit having an inhalation circuit and an exhalation circuit. The inhalation circuit includes a first solenoid-operated valve and a first check valve. The exhalation circuit includes a vent valve, a dehumidifying chamber, a pressure detector, a second check valve, and a second solenoid-operated valve. A central processor closes the first solenoid-operated valve and the second solenoid-operated valve based on a respiration control signal supplied from a synchronizing signal output control device, disconnecting the respiratory system of the controlled body from the outside of the respiration control apparatus.
