Patent number: 8740824Abstract: 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.Type: GrantFiled: October 30, 2007Date of Patent: June 3, 2014Assignee: Electromed, Inc.Inventors: Craig N. Hansen, Paul C. Cross, Lonnie J. Helgeson

Patent number: 7374550Abstract: 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.Type: GrantFiled: April 7, 2005Date of Patent: May 20, 2008Assignee: Electromed, Inc.Inventors: Craig N.
