Abstract
Abstract A bathroom sink, cabinet structure, or the like supports adjacent to the basin a tank holding a medicated douche liquid which is fluid coupled to one end of an extendable flexible hose which terminates at its other end in either a spray head or a replaceable douche probe. A rotary selection valve also respectively couples the spray handle to hot and cold pressurized water lines leading from the sink faucet, and energizes a pump motor associated with the douche liquid container for pumping liquid from the container under pressure to the spray handle, when fluid connection is made thereto.

Claim 1
Independent Claim
320 words
A pressurized liquid applicator system for selectively applying diverse liquids to the human body, said system adapted for use with a bathroom sink structure having a basin supported on a counter top thereof, said system having a first presssurized liquid source in the form of a hot and cold water faucet overlying said basin and a second pressurized liquid source in the form of a storage tank for liquid medicament mounted on said counter top, a rotary valve assembly fixed to the bottom of said counter top and including a cylindrical valve casing whose axis is substantially at right angles to the plane of the counter top, said casing having a plurality of radial circumferentially spaced bores defining liquid inlet openings, said liquid inlet openings being fluid coupled to said tank and said hot and cold water faucet respectively, said casing having an axial bore which intersects said radial bores, a cylindrical valve member disposed for rotation within said casing axial bore, said valve member having an axial bore and a radial opening leading therefrom, the casing axial bore being aligned with the axial bore of the valve member and defining therewith a liquid discharge opening for said valve assembly, an extensible hose terminating in a liquid applicator and being coupled with said discharge opening for the valve assembly, said radial opening of said cylindrical valve member rotatable with the valve member into selective registration with the radial bores of the valve casing, whereby said discharge opening and hose are selectively fluid coupled with said first and second pressurized liquid sources, a rotary valve shaft secured to said valve member and having a handle fixed thereto above said counter top, pump means operatively associated with said tank, and means automatically responsive to operation of said rotary valve assembly for energizing said pump means in order to deLiver said liquid medicament from said tank to said rotary valve assembly under pressure.
Claim 2

320 words
A pressurized liquid applicator system for selectively applying diverse liquids to the human body, said system adapted for use with a bathroom sink structure having a basin supported on a counter top thereof, said system having a first presssurized liquid source in the form of a hot and cold water faucet overlying said basin and a second pressurized liquid source in the form of a storage tank for liquid medicament mounted on said counter top, a rotary valve assembly fixed to the bottom of said counter top and including a cylindrical valve casing whose axis is substantially at right angles to the plane of the counter top, said casing having a plurality of radial circumferentially spaced bores defining liquid inlet openings, said liquid inlet openings being fluid coupled to said tank and said hot and cold water faucet respectively, said casing having an axial bore which intersects said radial bores, a cylindrical valve member disposed for rotation within said casing axial bore, said valve member having an axial bore and a radial opening leading therefrom, the casing axial bore being aligned with the axial bore of the valve member and defining therewith a liquid discharge opening for said valve assembly, an extensible hose terminating in a liquid applicator and being coupled with said discharge opening for the valve assembly, said radial opening of said cylindrical valve member rotatable with the valve member into selective registration with the radial bores of the valve casing, whereby said discharge opening and hose are selectively fluid coupled with said first and second pressurized liquid sources, a rotary valve shaft secured to said valve member and having a handle fixed thereto above said counter top, pump means operatively associated with said tank, and means automatically responsive to operation of said rotary valve assembly for energizing said pump means in order to deLiver said liquid medicament from said tank to said rotary valve assembly under pressure.
Claim 3
Dependent Claim
92 words
The structure of claim 1, wherein said rotary valve shaft carries a radial cam, and a microswitch and a microswitch actuator, said microswitch being operatively positioned relative to said cam such that said microswitch actuator contacts the radial cam periphery and said microswitch changes state in response to rotation of said rotary valve shaft, and also including an electrical motor which drives said pump means and said microswitch controls energization of the pump means drive motor in response to fluid coupling of said tank to said hose via said rotary valve assembly.
Claim 4
Dependent Claim
75 words
The structure of claim 2, wherein said radial bores of said valve casing are counterbored at their radially inner ends, tubular neoprene seals carried within the counterbored portions of said radial bores and having their inner ends spring biased against the periphery of said cylindrical valve member to effectively seal said inlet openings from each other and permit discharge of fluid from any one inlet opening only through said discharge opening of said valve assembly.
Claim 5
Dependent Claim
60 words
The improvement as claimed in claim 3, wherein said tubular neoprene seals are counterbored at their radially outer ends and said spring biasing means each comprise a coil spring having one end contacting the shoulder created by the counterbore within its tubular neoprene seal and its other end contacting the shoulder created by the radial counterbore in said valve casing.
Claim 6
Dependent Claim
205 words
A pressurized liquid applicator system comprising a sink counter top, an upright axis rotary selector valve assembly secured to the bottom of said counter top and having a manipulating handle arranged above the counter top, a tank for a liquid medicament supported by the counter top and including a delivery pump beneath the counter top, said rotary selector valve assembly having a liquid inlet and said inlet being fluid coupled with said delivery pump, hot and cold water conduits beneath said counter top, said selector valve assembly having additional liquid inlets which are fluid coupled to said conduits, said rotary selector valve assembly having a liquid outlet common to said first and second named liquid inlets, said valve assembly including a rotary member coupled with said manipulating handle and having a port movable selectively into registration with any one of said liquid inlets and having a passage communicating with said port and being in registration with said liquid outlet, an extensible hose terminating in a liquid applicator and being accessible above said counter top and being coupled with said liquid outlet of said selector valve assembly, and control means for said delivery pump activated in response to rotation of said handle above said counter top.
