Abstract
Abstract Hydrotherapy equipment adapted for use with a conventional bathtub. The nozzle and aspirator of this device is provided with a fitting that is inserted into a small valve mechanism that is located in the drain of the bathtub. A pipe is connected to this valve mechanism and this pipe extends down through the drain and is connected to the pressure side of a water pump through a directional valve. The water supply line is also connected to the bottom of this valve mechanism through another directional valve. The drain of the bathtub is connected to the suction side of the pump and a bypass which is provided with an adjustable pressure relief valve is connected so that water from said pump is circulated therethrough when the valve mechanism in the bathtub drain is closed, that is, when the fitting attached to the nozzle and aspirator is removed from the valve mechanism.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
178 words
In hydrotherapy equipment adapted for use with a conventional bathtub which is provided with a drain in the bottom thereof, the combination comprising a valve mechanism located in said drain so that it is accessible from the inside of the bathtub, the top of said mechanism being substantially flush with the opening of said drain into the bathtub, a pipe connected to said valve mechanism, said pipe being attached to said drain and projecting out of said drain below said bathtub, a pump, a motor for driving said pump, means connecting the inlet of said pump to said drain, means connecting the outlet of said pump to the part of said pipe projecting out of said drain below said bathtub, the valve of said mechanism being normally closed, a tubular member adapted to be inserted into said valve mechanism to open said valve, and a nozzle attached to said tubular member, said pump outlet supplying water to said nozzle from said drain when said tubular member is inserted into said valve mechanism and said valve thereof is open.
Claim 2
Dependent Claim
178 words
In hydrotherapy equipment adapted for use with a conventional bathtub which is provided with a drain in the bottom thereof, the combination comprising a valve mechanism located in said drain so that it is accessible from the inside of the bathtub, the top of said mechanism being substantially flush with the opening of said drain into the bathtub, a pipe connected to said valve mechanism, said pipe being attached to said drain and projecting out of said drain below said bathtub, a pump, a motor for driving said pump, means connecting the inlet of said pump to said drain, means connecting the outlet of said pump to the part of said pipe projecting out of said drain below said bathtub, the valve of said mechanism being normally closed, a tubular member adapted to be inserted into said valve mechanism to open said valve, and a nozzle attached to said tubular member, said pump outlet supplying water to said nozzle from said drain when said tubular member is inserted into said valve mechanism and said valve thereof is open.
Claim 3
Dependent Claim
77 words
In hydrotherapy equipment adapted for use with a conventional bathtub which is provided with a drain in the bottom thereof, the combination as set forth in claim 1, further comprising a bypass connected between said pump inlet an outlet and an adjustable pressure relief valve connected in said bypass so that when said valve mechanism is closed water pumped by said pump is circulated through said bypass at pressure determined by the setting of said relief valve.
Claim 4
Dependent Claim
55 words
In hydrotherapy equipment adapted for use with a conventional bathtub which is provided with a drain in the bottom thereof, the combination as set forth in claim 1, further characterized in that said tubular member and said valve mechanism are provided with cooperating means for releasably holding said tubular member assembled with said valve mechanism.
Claim 5
Dependent Claim
44 words
In hydrotherapy equipment adapted for use with a conventional bathtub which is provided with a drain in the bottom thereof, the combinations as set forth in claim 3, further characterized in that said nozzle is attached to said tubular member by a flexible hose.
