Pulsator

An apparatus for providing repetitive pressure pulses to a portion of a person to assist body functions comprising:

• means for accommodating air under pressure including at least one flexible member adapted to engage a portion of a person and an enclosed first internal chamber located within the flexible member that is to be subjected to repetitive pressure pulses, a pulsator operable to produce air pressure pulses, hose means connecting the pulsator with the flexible means, said hose means having an air passage open to the first chamber whereby the air pressure pulses repetitively move the flexible means which applies pressure pulses to the portion of a person, said pulsator having housing means including an enclosed second chamber, diaphragm means located within said second chamber dividing the second chamber into a first chamber means and a second chamber means, means for supplying air to the first chamber means, check valve means for maintaining the pressure of the air within said first chamber means and said first chamber when the means for supplying air under pressure is not operating, coil means for vibrating the diaphragm means to pulsate the air in the first chamber means, said hose means being connected to the housing means and open to the first chamber means whereby the air in said first chamber is pulsated, which in turn subjects the portion of a person to repetitive pressure pulses, wave generator means for generating a wave signal, and means connecting the wave generator means to the coil means whereby the signal from the wave generator means energizes the coil means, which vibrates the diaphragm means to pulsate the air in said first chamber means and first chamber.
