Body pulsating method and apparatus

摘要

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.

1. An apparatus for applying pressure and high frequency pressure pulses to the upper body of a person comprising:
a vest having a chamber for accommodating air adapted to be placed about the upper body of a person, an air pressure and high frequency air pressure pulse generator for supplying air under pressure and air pressure pulses to the chamber of the vest, said generator having diaphragms, an air pulsing chamber located between the diaphragms, air pumping chambers associated with the diaphragms, a manifold chamber open to the air pumping chambers to allow air to flow from the air pumping chamber into the manifold chamber, a check valve allowing air to flow from the manifold chamber to the air pulsing chamber and prevent air from flowing from the pulsing chamber to the manifold chamber, a power transmission operable to move the diaphragms to pump air in the pumping chambers and pulse air in the pulsing chamber, a single electric motor drivably connected to the power transmission for moving the diaphragms for different periods of time and varying speeds to generate air pressure and high frequency air pressure pulses in the pulsing chamber, a member having an air passage connecting the air pulsing chamber of the generator to the vest for transferring air pressure and high frequency air pressure pulses from the generator to the chamber of the vest whereby high frequency pressure pulses are applied to the upper body of the person, an electric motor controller operable to connect an electric power supply to the electric motor, said controller including first programmable electronic components for controlling the time of operation of the electric motor to change the duration of operation of the generator and second programmable electronic components for controlling the speed of the electric motor to change the frequency of the pressure pulses, said controller including electronic components for randomly controlling the speed of the electric motor thereby randomly changing the frequency of the pressure pulses, an airflow regulator for restricting the flow of air into the manifold chamber of the generator to control the pressure of the air discharged by the generator to the chamber of the vest, said regulator including a valve having a passage to allow air to flow through the valve, an air flow restrictor located in the passage to regulate the flow of air through said passage, and a control having a manually operated member connected to the restrictor to adjust the position of the restrictor in the passage thereby adjust the rate of flow of air through the passage and into the manifold chamber of the generator thereby manually controlling the pressure of the air in the chamber of the vest.
