Thepump has three valvular actions: 1. The first is that of pressure. It forces a column of air againstthe part, like the tapping of a hammer. It has an almost humajitouch of great delicacy. 2. The second is an alternating action that gives a vibratoryeffect, shaking the skin up and down from 250 to 10,000 times perminute, depending upon the speed of the motor. 3. The third is that of suction or dry cupping. The extentand duration of the vacuum is under the control of the operator, whocan instantly relieve the pressure by raising his finger even when themotor is at its maximum speed. It will be seen that all the movements of the skilled masseurcan be made by the pneuma-massage pump. The cups can be madeof any material, but glass is preferable for the reason that you canalways see what you are doing and the smooth edges fit the cups can be made in all sizes, about six being all that are neededfor general work. If desired, the galvanic or galvano-faradic current. Plate 270.—A Motor-Massage Vibration Apparatus. Tlie various applicators attachin a or a in the rotating device at the end of the flexible handle running from the electricmotor as shown in the figure. For further description see Plate 271.
