Abstract:
A massage apparatus having a vibratory massage plate, the vibratory motion of which is derived from a drive unit rotated by an electric motor and an insertable portion of a drive shaft in operative engagement with the drive unit. In order to perform underwater massage in addition to dry vibration massage, the invention provides for a container having a drive shaft rotatably mounted in its bottom portion. The drive shaft has an impeller or the like mounted thereon inside the container and has an insertable portion on the shaft projecting from the underside of the container bottom. The massage plate has an opening in the area of the drive unit to receive the insertable portion of the drive shaft, and on insertion of the insertable portion of the drive into a receptacle of the drive unit, an operative engagement between the insertable portion of the drive shaft and the drive unit is established. Disengagement of the drive unit and the insertable portion of the drive shaft is effected by axial movement of the drive unit.
Abstract:
This invention relates to an air turbulence massage device having a control device with a blower unit and a turbulence matting which can be placed in a bathtub. The turbulence matting can be connected with the blower unit outlet by means of an air tube. The turbulence intensity, using a preset program, can be adjusted and changed between a lower and an upper value by varying the rotational speed of the blower unit. To achieve siultaneous switching times with the turbulence process, this invention provides that the lower value is preset as a minimum pressure value which is enough to overcome a counter-pressure predetermined by a normal water level in the bathtub. The upper value is preferably preset as an adjustable maximum pressure value. At predetermined time intervals, the turbulence intensity can be abruptly switched between the predetermined minimum pressure value and the predetermined maximum pressure value and/or can be changed at predetermined time intervals which alternately increase and decrease the turbulence intensity.
Abstract:
An air bubble hydromassaging apparatus having a blower housed in a control unit, a bubble grid adapted to be placed in a bathtub, and air tubing enclosing a check valve to connect the control unit to the bubble grid. The control unit is provided with a bushing type compressed air outlet and the bubble grid is provided with a bushing type compressed air inlet. The air hose has a connector fitting on each end by which it is detachably and airtightly connected to the compressed air outlet of the control unit at one end and to the compressed air inlet of the bubble grid at the other end. A check valve built into the connector fitting serves to obstruct passage through the connector fitting when the blower is inoperative and opens to permit passage through the connector fitting when the blower is operative. Due to the particular construction of the air hose connector fittings and their specially defined association with the compressed air outlet of the control unit and the compressed air inlet of the bubble grid, and further in view of the reflux preventing check valve which is built into one of the air hose fittings, an absolutely safe operation of the device is achieved. The air bubble hydromassaging apparatus is functional only when the proper ends of the air hose are respectively connected to the control unit and the bubble grid, whereby the direction of passage of the check valve is automatically established.
Abstract:
An external automatic defibrillator including an attachment device that can be externally attached and carried by a patient, an identification device for detecting an abnormal event in the cardiac activity, which can be treated by an electric shock, as well as a defibrillator allowing to exert a shock upon the patient after having detected the abnormal event. In order to ensure reliable functioning over a longer period of time, the identification device is configured so that the identification device can detect an abnormal event in an interval of not more than 90 seconds or one minute.

Abstract:
A blower for an air spray bath massaging apparatus, which blower is operated by an electric motor and is enclosed in a housing having a suction air fitting and a compressed air fitting. To effectively reduce the suction noise of the blower, the suction air fitting is provided with a closure wall having a plurality of suction sleeves with suction inlets. The suction air current is divided into several smaller air currents by which considerably less suction noise is generated.
Abstract:
A defibrillator including an output stage that has a high-voltage section and patient electrode connections which can be automatically connected by a coupling circuit to said high-voltage section via a relay, and that has a relay testing device. A reliable functioning of the defibrillator is ensured due to the provision of a discharging resistor device which can be automatically switched to instead of the patient electrode connections by the relay, and because the relay testing device is designed for testing the relay while involving the state of the adjacent discharging resistor device.
Abstract:
A defibrillator including an output stage, which is controlled by a control circuit for emitting a biphasic defibrillation pulse and which has an H-bridge between a positive pole and a negative pole of an energy accumulator device. A patient electric circuit is provided in a shunt arm having at least one inductive resistor. This invention achieves a reliable functioning of the defibrillator and thus to regulate the patient current in one direction, only the switching element, which is assigned to this current direction and which is located in the H-limb that points toward the negative pole, is controlled with the higher frequency, whereas in order to regulate the patient current in the other direction, only the switching element, which is assigned to this other current direction and which is located in the H-limb that points toward the positive pole, is controlled with the higher frequency. This invention provides at least one diode that is arranged in an antiparallel manner with regard to the switching elements, which are controlled with the higher frequency, so that via each diode and the switching element, which is constantly closed in the respective phase, the patient current is maintained in its respective direction.
