Abstract
Abstract Respiration apparatus including a jacket having a collapsible bladder supported in the abdominal area of the patient. Pressurization means are connected to the bladder by conduit means; including a control valve having an exhaust port. Control means which may include cascaded fluidic amplifiers, controls flow of pressurization air through the valve and includes a sensing element for sensing the patients respiration cycle. The control means is responsive to a positive signal, caused by initial exhalation to direct air flow to the bladder to depress the abdominal muscles and assist the patient in exhaling. The control means is also responsive to a negative signal, caused by initial inhalation, to close the control valve and exhaust the bladder out the exhaust port.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
163 words
Respiration apparatus comprising: a jacket to be worm by a patient and including a bladder disposed therein; pressurization means; conduit means connecting said pressurization means with said bladder; control valve means in said conduit means for controlling flow of pressurization fluid to and from said bladder; a sensing device for periodically producing a positive pressure signal; and control means connected with said sensing device for controlling said control valve means, said control means including a first fluid amplifier formed with a primary passage having a fluid inlet connected with said pressurization means, a pressurization outlet connected with said bladder and a vent outlet, said control means further including directing means connected with said sensing device and responsive to said pressure signal to direct pressurization fluid in said primary passage out said pressurization outlet to inflate said bladder and responsive to an absence of said pressure signal to direct fluid in said primary passage out said vent outlet to enable said bladder to deflate.
Claim 2
Dependent Claim
163 words
Respiration apparatus comprising: a jacket to be worm by a patient and including a bladder disposed therein; pressurization means; conduit means connecting said pressurization means with said bladder; control valve means in said conduit means for controlling flow of pressurization fluid to and from said bladder; a sensing device for periodically producing a positive pressure signal; and control means connected with said sensing device for controlling said control valve means, said control means including a first fluid amplifier formed with a primary passage having a fluid inlet connected with said pressurization means, a pressurization outlet connected with said bladder and a vent outlet, said control means further including directing means connected with said sensing device and responsive to said pressure signal to direct pressurization fluid in said primary passage out said pressurization outlet to inflate said bladder and responsive to an absence of said pressure signal to direct fluid in said primary passage out said vent outlet to enable said bladder to deflate.
Claim 3
Dependent Claim
77 words
Respiration apparatus, as set forth in claim 1 wherein said sensing element includes; a mask for covering the nose of the patient and formed with a sense port confronting the patient''s nose and including an exhaust opening spaced from said sense port, whereby positive and negative pressure fluctuations will be communicated directly from the nOstrils to said sense port and resultant exhaled air will be exhausted out said exhaust opening and inhaled air will be admitted therethrough.
Claim 4
Dependent Claim
35 words
Respiration apparatus as set forth in claim 1 wherein: said control means includes relief means for sensing the pressure in said bladder and actuating said valve means at a predetermined pressure to deflate said bladder.
Claim 5
Dependent Claim
132 words
Respiration apparatus as set forth in claim 1 wherein: said control system includes a first fluid logic element having a primary passage defining a vent outlet and a pressurization outlet, said logic element also having a control port, said control system further including a first fluid power amplifier having a primary passage defining a vent outlet and a pressurization outlet, said power amplifier also including a vent control port and a pressurization control port, said control system further including conduit means connecting said pressurization outlet of said first fluid amplifier with said control port of said logic element, said pressurization outlet of said logic element with said pressurization control port of said power amplifier, and said vent outlet of said first fluid amplifier with said vent control port of said power amplifier.
Claim 6
Dependent Claim

Claim 8
Dependent Claim
54 words
Respiration apparatus as set forth in claim 1 wherein: said sensing device includes a face element for placing on a patient''s face to sense his respiration to produce said pressure signal whereby the patient''s respiration cycle may be sensed to alternately inflate and deflate said bladder in response to said patient''s natural respiration cycle.
Claim 9
Dependent Claim
35 words
Respiration apparatus as set forth in claim 1 wherein: said bladder is mounted in the central, lower front torso portion of said jacket to apply pressure to the abdomen and lower chest of said patient.
Claim 10
Dependent Claim
151 words
Respiration apparatus comprising: a jacket to be worn by the patient and including a bladder for disposition on the front of the torso; pressurization means; conduit means connecting said pressurization means with said bladder; control valve means in said conduit means and including a vent port; and control means for controlling said valve means and including power amplifier means having a primary passage defining a pressurization outlet and a vent outlet, said amplifier means also including a pressurization control port and a vent control port, said control means further including first and second feedback conduits connecting said pressurization outlet and vent outlet with said pressurization port and control port, respectively, said feedback conduits being formed with reservoir means, whereby pressurization fluid fed back through said conduits will effect periodic switching of flow in said primary passage between said pressurization outlet and said vent outlet to periodically pressurize and deflate said bladder.
