Respiratory vest for repetitive pressure pulses

A vest for applying repetitive pressure pulses to a human body comprising:

• a cover having an internal chamber and first and second end sections, a bladder located within the internal air chamber adapted to accommodate air pressure pulses which apply pressure pulses to a human body wearing the vest, fasteners permanently connecting the bladder to the cover, said bladder having flexible side walls secured together providing an air chamber for accommodating air, said side walls having bottom portions, an elongated sleeve joined to the bottom portions of the side walls having an air receiving passage, said bottom portions having at least one passage open to said air chamber and air receiving passage to allow air and air pressure pulses to flow from the air receiving passage into said air chamber, an elongated open flexible spring member located in said air receiving passage of the sleeve to allow air to flow in the air receiving passage, said cover having a pair of shoulder straps and chest portions, first releasable members connecting the shoulder straps to the chest portions, said first and second end sections of the cover being located in overlapping relation when the cover and bladder are located around the body of the person, second releasable members connecting the first and second end sections to hold the bladder and cover around the body of the person whereby when the bladder is subjected to air pressure pulses repetitive pressure pulses are transmitted to the body of the person.
