Abstract: The invention relates to an ultrasonic therapeutic device, which can be operated independently of an external power source. For longer periods of operation, for example by a trainer at a sports ground, the device can be operated using an external battery stack and for stationary operation, the electric power can be drawn from the mains supply. For reasons of safety, the emitted ultrasonic intensity is reduced in relation to medical therapeutic devices. The same device can be used to heat or cool the area to be treated. The device can also be set to emit electrical, magnetic and electromagnetic fields and for electro-physiotherapy with or without a separate second electrode. The emission head (1) therefore contains an oscillating element (3), Peltier elements (25) for heating and cooling and the electrodes (28, 29, 30) for electro-physiotherapy.

Abstract: The respiratory training device comprises a shell housing (1) with a detachable respiratory air channel (2) connected therewith, a mouthpiece (3), an air bag (5) and a control device (14). In the respiratory air channel (2) a valve configuration is installed and specifically a piston valve. This piston valve is equipped with a valve body, which is freely movable and does not have a fixed connection to the respiratory air channel (2). In the housing part (1) and/or in the housing of the valve configuration force-generating means are available, which retain the valve body in the sealing position and determine the necessary opening forces for the valve. All parts, which are in contact with respiratory air, can be removed and cleaned simply.
