Abstract: VIBRATORY METHOD AND DEVICE FOR TREATING FEMALE VOIDING DYSFUNCTIONS                 ABSTRACT OF THE DISCLOSURE A vibratory method for treating female voiding dysfunctions by applying to the inner walls of the urethra radial expansion forces combined with axial friction forces. This improves blood circulation, trains the urethral sphincters, and produces massaging action on the urethral walls.  A device for realization of the method comprises a probe (12) formed of two rods (16) and (18) and a drive unit (14).  Drive unit (14) have two output elements, which reciprocate simultaneously in mutually opposite directions. Each rod (16, 18) is connected to a respective drive unit. On their inner or mating surfaces the rods have respective cams (32, 34) and curved grooves (36, 38). During reciprocation of the rods, the cams and grooves interact and thus provide radial expansions of probe (12).  Massaging action is provided by serrations (40) which are formed on the outer surface of the rods and massage the inner walls of the urethra through application of friction forces.  The rods can be made from plastic and used as a sterilized disposable unit.

Abstract: A strobe light circuit for flashing a flashtube at a desired frequency includes a transformer the primary of which is repetitively connected and disconnected across a D.C. power source by a switch so that energy stored in the primary winding during closed periods of the switch is transferred to the secondary winding of the transformer, with a step-up in voltage, during open periods of the switch, and through a diode to an energy-storing capacitor connected in parallel with the flashtube. The closed period of each switch cycle is initiated at regular intervals by a timing signal and the open period is initiated in response to the attainment of a predetermined voltage across a capacitor connected across the power source indicating that sufficient energy is being stored in the primary winding during each cycle such that the energy transferred to the energy-storing capacitor during the open period of all cycles occurring during one flash period will be sufficient to enable the flashtube to produce a flash when triggered.      A flash unit associated with the flashtube includes a trigger circuit that responds to two closely following trigger pulses to produce a double flash during each flash period. The flash rate is constant over a range of input voltages and the light intensity of each flash is independent of variations in capacitance of the energy-storing capacitor.
