Abstract
A portable emergency respirator which contains an electrical power supply, a source of compressed air, and a switch which allows one to produce three separate different types of pneumatic outputs from the source of compressed air. In one mode of operation, the output from the source of compressed air provides intermittent positive pressure ventilation to the patient. In a second mode of operation, the output from the source of compressed air is automatically synchronized with the patient's breathing. In a third mode of operation, the output from the source of compressed air is manually controlled by an operator.
Claims20
A portable emergency ventilating apparatus, wherein said ventilating apparatus is comprised of:
- (a) an electrical power supply;
- (b) a source of compressed gas;
- (c) a first means for producing a pulsed electrical signal, wherein said first means for producing an electrical signal is comprised of a timing circuit;
- (d) a second means for producing a pulsed electrical signal, wherein said second means for producing a pulsed electrical signal is comprised of means for sensing a patient's breathing;
- (e) a third means for producing a pulsed electrical signal, wherein said third means for producing a pulsed electrical signal is comprised of a first switching means, and wherein said first switching means is comprised of a switch;
- (f) second switching means for alternatively supplying power to said first means for producing a pulsed electrical signal, said second means for producing a pulsed electrical signal, and said third means for producing a pulsed electrical signal, wherein said second switching means is electrically connected to said power supply;
- and
- (g) means for sending said pulsed electrical signal to said source of compressed gas.
