A device and method coupled to a therapy garment to apply pressure and repetitive compression forces to a body of a person has an air pulsator and a user programmable time, frequency and pressure controller operable to regulate the duration of operation, frequency of the air pulses and a selected air pressure applied to the body of a person.

Air pulsator control system

Air pulsating generator

A vest for a human body has an air core coupled to a pulsator operable to subject the vest to pulses of air which applies and releases high frequency pressure forces to the body. The pulsator has two diaphragms connected to a brushless electric dc motor with rotary to reciprocating linear motion transmitting mechanisms comprising scotch yokes having anti-lash assemblies operable to generate air pulses in an air pulsing chamber. The diaphragms also increase the pressure in a manifold chamber. A check valve connects the manifold chamber with a pulsing chamber to allow pressurized air to flow from the manifold chamber into the pulsing chamber. An air flow control valve in communication with the manifold chamber is used to adjust the pressure of the air in the manifold and pulsing chambers. A programmable motor controller adjusts the duration of operation and speed of the motor to vary the operational time and frequency of the air pulses.

Body pulsating method and apparatus

A portable human body pulsating apparatus has an air pulse generator mounted on a pedestal having wheels to facilitate movement of the apparatus on a surface. The pedestal has an upright piston and cylinder assembly operable to adjust the elevation of the air pulse generator. A reversible thoracic therapy garment is connected with a hose to an air pulse generator which can be selectively located adjacent opposite sides of a person receiving therapy.

Portable air pulsator and thoracic therapy garment

Thoracic garment

Scotch yoke with anti-lash assembly

A portable human body pulsating apparatus has an air pressure and air pulse generator located within a case mount on a pedestal having wheels to facilitate movement of the apparatus on a surface. The pedestal has an upright piston and cylinder assembly operable to adjust the elevation of the case and generator.

Combined air pulsator and movable pedestal

A vest for a human body has a bladder coupled to a pulsator operable to subject the vest to repeated pulses of air which applies and releases pressure to the body. The vest has a cover having a pocket accommodating the bladder, shoulder straps, and end flaps. The bladder is permanently connected to the cover. Releasable hook and loop fasteners connect the straps to chest portions of the vest and end flaps to each other. A releasable retainer secured to the end flaps prevent the end flaps and releasable fasteners from disengaging when air pressure pulses are applied to the vest. The bladder has an air chamber and a sleeve having an air receiving passage and openings to allow air to flow from the air receiving passage into the air chamber. An oval-shaped coil spring within the sleeve maintains the air receiving passage open.

Respiratory vest for repetitive pressure pulses

A vest for a supine human has a one-piece cover with a front panel secured to a bladder coupled to a pulsator operable to subject the vest to repeated pulses of air which applies and releases pressure to the front of the thorax of a person. The bladder has an air chamber and a bottom transverse portion having an air receiving passage and openings to allow air to flow from the air receiving passage into the air chamber. A coil spring within the air receiving passage maintains the air receiving passage open to allow air and air pressure pulses to flow into the air chamber.
