Pulsator

An apparatus for providing repetitive pressure pulses to first and second portions of a person comprising:

• means having first and second flexible air-accommodating means engageable with the first and second portions of a person that are to be subjected to repetitive pressure pulses, a pulsator operable to produce first and second air pressure pulses, first hose means connecting the pulsator with the first air-accommodating means whereby the first air pressure pulses provided by the pulsator repetitively move the first air-accommodating means which applies first pressure pulses to said first portion of a person, second hose means connecting the pulsator with the second air-accommodating means whereby the second air pressure pulses provided by the pulsator repetitively move the second air-accommodating means unsynchronized with the repetitive movement of the first air-accommodating means thereby applying second pressure pulses to said second portion of a person at different intervals from the application of the first pressure pulses to the first portion of a person, said pulsator having housing means including an enclosed chamber, diaphragm means located within said chamber dividing the chamber into a first chamber means and a second chamber means, means for supplying air under pressure to the first and second chamber means, coil means for vibrating the diaphragm means to pulsate air in the first and second chamber means at different intervals, said first hose means being connected to the housing means and open to the first chamber means whereby air in said first air-accommodating means is pulsated, which in turn subjects the first portion of a person to the first pressure pulses, said second hose means being connected to the housing and open to the second chamber means whereby air in the second air-accommodating means is pulsated in opposite rhythmic pattern from pulsation of air in the first air-accommodating means, subjecting the second portion of a person to the second pressure pulses at different intervals from the first pressure pulses applied to the first portion of a person, 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 air alternately in said first and second chamber means.

An apparatus for providing repetitive pressure pulses to first and second portions of a person comprising:

• means having first flexible air-accommodating means engageable with the first portion of a person that is to be subjected to repetitive pressure pulses and second flexible air-accommodating means engageable with the second portion of a person that is to be subjected to repetitive pressure pulses, a pulsator operable to produce first and second air pressure pulses, first means having an air passage connecting the pulsator with the first air-accommodating means whereby the first air pressure pulses provided by the pulsator repetitively move the first air-accommodating means which applies pressure pulses to the first portion of a person, second means having an air passage connecting the pulsator with the second air-accommodating means whereby the second air pressure pulses produced by the pulsator move the second air-accommodating means unsynchronized with the repetitive movement of the first air-accommodating means which applies pressure pulses to the second portion of a person at different intervals from the application of pressure pulses to the first portion of a person, said pulsator having housing means including an internal chamber, diaphragm means located within said internal chamber dividing the internal chamber into a first chamber and a second chamber, means for supplying air under pressure to the chambers, means for vibrating the diaphragm means to pulsate air in the chambers at different intervals, the air passage of the first means being connected to the housing means and open to the first chamber whereby air in said first air-accommodating means is pulsated, which in turn subjects the first portion of a person to repetitive pressure pulses, the air passage of the second means being connected to the housing means and open to the second chamber whereby air in said second air-accommodating means is pulsated opposite from the pulsation of air in the first air-accommodating means subjecting the second portion of a person to repetitive pressure pulses at different intervals from the pressure pulses applied to the first portion of a person, wave generator means for generating a wave signal, and means connecting the wave generator means to the means for vibrating the diaphragm means whereby the wave signal from the wave generator means energizes the means for vibrating the diaphragm means to pulsate air alternately in said first and second chambers and first and second air-accommodating means.
