A pneumatically actuated impact tool, for use by trained personnel in chiropractic treatment of the spine and other parts of the body, includes a resiliently tipped plunger reciprocably mounted in a cylinder having a tank, with a fitting for connection to a source of air under pressure. Air pressure is selectively communicated to the cylinder and thereby to the plunger by a valve mounted in an aperture in a wall separating the tank and the cylinder, and engaged by a valve lever which is pivoted ...

A self-operated device for strengthening one's abdominal muscles by means of the impact from a padded cushion, simulated medicine ball or the like and/or the muscular pull in avoiding such impact, on or about the lower torso. The device comprises a pivotally mounted conversely bent rod having an upper cushion which when pushed away from the user will automatically force a lower cushion toward that portion of one's body to be toned thereby. The rod is pivotally mounted on a vertically adjustable ...

Shoulder patting device comprising a grip stick, two resilient plates which extend from one end of the grip stick in the form of Y-shape and first and second tip members which are respectively secured to the tips of the resilient plates.

A percussor assembly comprises a rigid body member having a gas inlet passageway and gas outlet passageway, a movable gas sealing member, and a gas pressure chamber communicating with the gas inlet passageway, the gas sealing member being forced from a first position forming a gas-tight seal between the gas pressure chamber and the gas outlet passageway to a second position in which the chamber and passageway are in communication to allow a burst of gas to pass from the chamber into the outlet p...

A pneumatic percussor includes a three-way valve that is gated on by a control circuit (50) to gate compressed air from a compressor (10) to a percussor cup (70). The percussor cup (70) is a resilient bellows that is expandable in response to pressurized air that is gated through the three-way valve (28). A variable orifice (62) regulates the air flow to the percussor cup (70). A check valve (60) is connected in parallel with the variable orifice (62) to exhaust air to the atmosphere. The contro...

A reciprocal cardiac compressor is provided for cyclically compressing a patient's chest. Preferably a resuscitator is also provided for ventilating the patient's lungs. The compressor includes a reciprocal compressor pad positioned anterior to the patient's heart and a stationary base positioned posterior to the patient's heart. An anterior electrode is disposed on the face of the compressor pad for compression between the compressor pad and the patient's sternum and a posterior electrode is di...

A bamboo massage stick according to the invention comprises a massage portion having a culm portion at end thereof and a shaft. The massage portion is coupled to the shaft in the configuration of ".right brkt-top." or letter "T". The whole weight of the massage stick is light because it is made of bamboo, and has advantage in that the massage stick has therapeutic value by use of compressed air. The massage stick can be produced on a large scale by simple manufacturing process.

Apparatus for effecting massages synchronously with the heart activity, and particularly with the interphases of this activity, and comprising, in combination, a visual indicator of electrical pulses provided with two independent input channels, both connected to respective sensors applicable to the individual; a discriminator parallel-connected to one of said visual pulse-indicator units, while the output thereof is fed to a signal generator which, in turn, is connected to at least one time mar...

A cardiopulmonary resuscitator massager pad is provided comprising a compressible, fluid filled enclosure adapted for mounting on the reciprocal piston of a cardiopulmonary resuscitator. The massager pad includes means for restricting lateral expansion of the enclosure and a face including means for evenly distributing the pressure of the fluid in the enclosure on the patient's chest.

A medical appliance for use in percussive respiratory therapy comprises a partially enclosed cavity which presents a substantially circular opening bordered by an annular ring of moldably compressible material for effecting a pneumatic seal of the cavity to a body area against which it is placed. The annular ring defines a groove to communicate with a curling semi-circular lip, the ring also defining a cavity filled with a compressible gaseous vapor for cushioning the impact of the appliance wit...
