摘要： An electromagnetic valve system for carrying out a compressed air supply to and evacuation from a plurality of air chambers of massage instruments of a pneumatic massage device includes a plurality of first electromagnetic valves each to be connected to a corresponding one of the air chambers; a second electromagnetic valve including a first aperture which communicates with external air; and a plurality of first check valves each within a header in an intermediate location between the second electromagnetic valve and a corresponding one of the air chambers with a connection tube therebetween, the first check valves allowing air to pass from the air chambers toward the second electromagnetic valve only when air pressure on a second electromagnetic valve side is lower than air pressure on an air chamber side.

摘要： A pneumatic massage apparatus making it possible to perform even more efficient drainage is provided.A pneumatic massage apparatus includes a massage device to be fitted to wrap around at least one of an arm or leg of a patient and having a plurality of air chambers disposed in series in a proximal direction from a distal position of the at least one of an arm and a leg toward the center of the patient's body, and a compressed air control unit configured to supply compressed air into the plurality of air chambers to pressurize them, and discharge compressed air from the plurality air chambers to depressurize them. The compressed air control unit is configured to depressurize the pressurized air chambers in such a manner that, of any pair of mutually adjacent air chambers, a proximal air chamber of the pair first starts to be depressurized, and then a distal air chamber of the pair starts to be depressurized.
