WIRELESS ELECTRONIC PUMP DESIGN FOR A BODY CAVITY IRRIGATION DEVICE
FIG32 is a perspective view of the pump base unit with the cover and reservoir removed to expose the pump/motor and the solenoid valves
Looking at FIG32, inside the shell 490 there is a mounting plate 504 which supports an electric motor 506, a pump 508 and five solenoid valves. The solenoid valves include a reservoir flow director valve 510, a pump flow director valve 512, a catheter valve 514, a balloon valve 516, and a waste valve 518. Solenoid valves 510 and 512 are normally-open, three-way valves. Solenoid valves 514, 516 and 518 are normally-closed, two-way valves. Not shown but present within the shell 490 are a rechargeable battery for powering the pump 508 and internal tubing which provides various fluid connections among the solenoid valves 510-518, the reservoir conduit, the pump 508 and the fitting 498. The fluid connections provided by the internal tubing are described below in the fluid circuit diagrams.

['1. A liquid supply, comprising: a pump base unit having a housing; a conduit formed in the housing, the conduit having an external surface and an internal fluid passageway therethrough; a reservoir mounted on the pump base unit in fluid communication with the passageway of the conduit; and a temperature sensor mounted on the conduit in contact with the external surface thereof.', '3. The liquid supply of claim 2 wherein the reservoir further comprises an aperture therein and a check valve mounted for closing the aperture when the reservoir is removed from the pump base unit and for opening the aperture when the reservoir is mounted on the pump base unit.', '6. The liquid supply of claim 5 wherein the boss has at least one thin-wall section and the temperature sensor is mounted in contact with the thin-wall section.']
