Abstract:
A combined jacket for applying repetitive pressure pulses to a human body and a pulsator for generating air pressure pulses which are transmitted to the jacket comprising: a jacket adapted to be placed about the body of a person, said jacket having an outer cover, a flexible liner attached to the cover, and an air core located between the cover and liner, a pulsator for generating air pressure pulses, means for carrying air from the pulsator to the air core whereby the air core is subjected to air pressure pulses generated by the pulsator, said pulsator including a casing having an internal air chamber, said means for carrying air being in communication with the air chamber, diaphragm means connected to the casing open to the internal air chamber, a motor having a drive shaft, a motion transmitting mechanism located within the internal air chamber drivably connecting the drive shaft of the motor to the diaphragm means operated in response to rotation of the drive shaft to move the diaphragm means relative to the air chamber to increase and decrease the pressure of the air in the air chamber thereby generating repetitive air pressure pulses, and means for supplying air to said internal air chamber to provide the air core with air.
