Abstract: Medical vest for High Frequency Chest Wall Oscillation (HFCWO) system, comprising at least a device comprising a deformable chamber and at least a port in communication with the chamber configured to let a pressurized fluid flowing alternatively in and out the chamber so that the inflatable device alternatively passes from an inflated configuration to a deflated configuration, characterized in that the device is configured to essentially expand along one single direction when passing from the deflated configuration to the inflated configuration.

Abstract: A system for providing continuous high frequency oscillation therapy is disclosed. A pulse generator comprises a valve stem which fluidly connects two ports when pressure in one of the two ports exceeds a threshold force. Fluidic connection between the two ports allows for fluid to flow back through an orifice and a needle valve to the pulse generator, the orifice and needle valve are components external to the pulse generator. Gases flowing through the needle valve and to the pulse generator apply a force on a diaphragm which deforms and pushes a valve button when gases flowing through the needle valve exceed a threshold. Motion of the valve button due to deformation of the diaphragm causes the valve button to exert force on the valve stem reducing fluid flow between the two ports.

Abstract: An air pulse generator provides a high frequency chest wall oscillation therapy to a patient wearing an inflatable garment. The air pulse generator includes a blower and a valve coupled to the blower and coupled to the inflatable garment. The valve is movable to apply an oscillating pressure to the inflatable garment. The valve may be a rotary valve or a solenoid valve.

Abstract: A gas supply system comprises a person-support surface, a garment, and a gas supply. The person-support surface includes a chamber configured to contain a gas therein. The garment includes a chamber configured to contain a gas therein. The gas supply is configured to supply a gas to both the garment and the person-support surface.

Abstract: A massage apparatus which provides a unique combination of mechanical oscillation (vibration) and suction to help break up the fat clusters and stretch fiber tissue by combining massage and strong localized suction to raise the skin and bring encapsulated fluids to the surface. The massage apparatus is designed to combine localized suction to raise the skin and contain fluids of a body part while simultaneously generating a high frequency vibration to maximize fluid flow and elongation of skin fibrous tissue to increase the flexibility and elasticity of the skin.

Abstract: A massaging device driven by a water wheel and having a plurality of fingers spread in concentric rings about an arched cover. The fingers are supported in and actuated by a rotating camming platform including a series of concentric camming surfaces with curved bases and irregularly shaped annular sidewalls. The fingers are reciprocated along their vertical axes to create a wave-like motion relative to the cover. Concurrently, the fingers are actuated to pivot about a central transverse axis defined by pin members located on opposite sides of the fingers. When driven by a water wheel, the device contains a water channel along its base, which channel extends to a water chamber containing the water wheel. The wheel is turned by water flow through the chamber thereby rotating the camming platform to which it is coupled by way of gears.

Abstract: The present invention is directed to a massager in which a massage unit comprising kneading rings on the right and left sides is mounted movably up and down inside thereof, and the massage unit is equipped with a plurality of air cells, each of the kneading rings being moved backward and forward or rightward and leftward by an expanding and contracting operation of the air cell or cells.
