Zusammenfassung: | 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. Reduction in fluid flow between the two ports causes drop in pressure of the gas flowing through the needle valve back into the pulse generator thereby reducing the force seeking to deform the first diaphragmnd move the valve button. The valve button falls back thereby allowing increased fluidic communication between the two ports again. This cyclical supply of high pressure gas is used for therapeutic purposes to provide high frequency oscillation. |
