  • Patent number: 4631061
    Abstract: A shallow collection vessel with liquid sensors and a resilient lip allows air around the genital-urinary area when not activated. Liquid urine in the vessel causes the sensors to activate a vacuum pump drawing the lip against the body of the user for a liquid tight seal and pumping the urine from the vessel through a tube and one-way valve to a temporary storage tank. Close and random spacing of the sensors creates a very sensitive device activated when the device is in any spacial orientation which might cause urine to contact the body by a minimal amount of urine, effecting the vacuum pump to remain active evaporating the urine within the vessel until the vessel is substantially dry. Paired electrical contacts or paired fibre optic elements are alternate liquid sensor means. Liquid level indicators within the tank signal a desired level for emptying and cause the pump to shut off upon reaching a dangerously full level. A condensation collecting trap keeps liquid out of the pump.
