Abstract
Abstract An apparatus and method for exercising the smooth muscles of the superficial veins of the legs and feet provide for supporting the patient in a reclining supine position with legs held horizontally in a relaxed condition over a water collecting pan. Surface areas of each foot and calf are subjected to predetermined contrasting temperatures in prescribed sequence and time intervals by means of water sprayed from nozzles onto the surface areas. The water temperature is monitored by temperature gauge means and is operator controlled by a mixing valve having a capability of delivering temperatures varying from a maximum of about 45° C to a minimum of about 21° C from conventional building hot and cold water supply sources. Adjustable means supports the nozzles to accommodate the normal range of leg lengths diametric sizes.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
87 words
A method for exercising the smooth muscles of the veins of the legs and feet comprising the steps of reclining the patient in a supine position wth legs outstretched in horizontal alignment with the body and supported solely above the knees and at the heels, and directing sprays of water against opposite sides of each foot and calf according to a predetermined cycle of times and temperatures including a relatively low temperature for contracting the smooth muscles and a relatively high temperature for relaxing the smooth muscles.
Claim 2
Independent Claim
87 words
A method for exercising the smooth muscles of the veins of the legs and feet comprising the steps of reclining the patient in a supine position wth legs outstretched in horizontal alignment with the body and supported solely above the knees and at the heels, and directing sprays of water against opposite sides of each foot and calf according to a predetermined cycle of times and temperatures including a relatively low temperature for contracting the smooth muscles and a relatively high temperature for relaxing the smooth muscles.
Claim 3
Dependent Claim
39 words
The method defined on claim 1 in which said predetermined cycle includes 1 minute intervals for changing the temperature of said sprays by mixing water from hot and cold water sources from one of said temperatures to the other.
Claim 4
Dependent Claim
97 words
The method defined in claim 1 in which said predetermined cycle of times and temperatures comprises initially raising the spray temperature from 37° to 45° C, maintaining the 45° C for 3 minutes, lowering the temperature to 21° C during a change interval of 1 minute, maintaining 21° C for 3 minutes, raising the temperature to 45° C during a change interval of 1 minute, maintaining 45° C for 3 minutes, lowering the temperature to 21° C during a final change interval of 1 minute and maintaining the temperature at 21° C for a final 3 minutes.
Claim 5
Independent Claim
176 words
An apparatus for exercising the smooth muscles of the veins of the legs and feet comprising a water collecting pan connected to a drain facility, a horizontal surface for a patient to lie on in a supine relaxed position with legs outstretched and extending horizontally over said pan, rest surface means associated with said pan for supporting each leg in said outstretched horizontal position by contacting the underside of each thigh and heel, each leg otherwise being freely suspended between the thigh and heel, eight spray nozzles, each connected to a water conduit, supported and located to simultaneously direct sprays of water to predetermined areas on opposite sides of each of said suspended feet and calves, means for sensing the temperature within the water conduit and displaying same, means connecting said water conduit to hot and cold water sources through an interposed manually operable mixing valve, and means for supporting said mixing valve in accessible relation to said pan for convenient manipulation by an operator while viewing the patient's legs and observing said temperature display means.
Claim 6
Independent Claim
176 words
An apparatus for exercising the smooth muscles of the veins of the legs and feet comprising a water collecting pan connected to a drain facility, a horizontal surface for a patient to lie on in a supine relaxed position with legs outstretched and extending horizontally over said pan, rest surface means associated with said pan for supporting each leg in said outstretched horizontal position by contacting the underside of each thigh and heel, each leg otherwise being freely suspended between the thigh and heel, eight spray nozzles, each connected to a water conduit, supported and located to simultaneously direct sprays of water to predetermined areas on opposite sides of each of said suspended feet and calves, means for sensing the temperature within the water conduit and displaying same, means connecting said water conduit to hot and cold water sources through an interposed manually operable mixing valve, and means for supporting said mixing valve in accessible relation to said pan for convenient manipulation by an operator while viewing the patient's legs and observing said temperature display means.
Claim 7
Dependent Claim
116 words
The apparatus defined in claim 4 in which said water conduit and spray nozzles are formed as a water spray assembly comprising three parallel, coplanar, uniformly spaced branches which emanate from a 4-way coupling, right and left branches of said assembly each having a pair of spaced T-couplings, each mounting one of said spray nozzles at right angles to the respective branch, the middle branch having a pair of 4-way couplings aligned with said T-couplings, each mounting a pair of oppositely facing spray nozzles, each of which coact with the nozzle on the adjacent branch as a nozzle pair directing sprays to one of said predetermined areas on the opposite sides of said calves or feet.
Claim 8
Dependent Claim
51 words
The apparatus defined in claim 5 in which one of said branches terminates at a closed end beyond said T-coupling or 4-way coupling in said temperature display means and has said sensing means projecting from the display means through and along the branch to the region of one of its nozzles.
Claim 9
Dependent Claim
79 words
The apparatus defined in claim 5 in which said water collecting pan is sink-like and has vertical side, rear and front walls, said front wall being of predetermined height above a bottom, the latter having an area for accommodating said water spray assembly, means providing said support and location for said water spray assembly including a base resting on said bottom, a plurality of collars mounted on said side branches, and support rods interconnecting said collars with said base.
Claim 10
Dependent Claim
53 words
The apparatus defined in claim 7 in which said rest surface means comprises the top of said front wall as the thigh support and a block resting on said bottom as the heel support, said block being movable forwardly and rearwardly on said bottom to adjust to the length of a patient's legs.
Claim 11
Dependent Claim
66 words
The apparatus defined in claim 8 in which said support rods and base are constructed and arranged to locate said water spray assembly a predetermined distance above the top of said front wall to align with the patient's legs, the connection of said support rods with said base being a series of holes of predetermined depth in which the lower ends of said support rods seat.
Claim 12
Dependent Claim
48 words
The apparatus defined in claim 7 in which said collars are sized to permit relative sliding movement of said branches therethrough for adjusting said water spray assembly forwardly or rearwardly with respect to said front wall, and set screw means for locking said collars in an adjusted position.
Claim 13
Dependent Claim
94 words
The apparatus defined in claim 5 in which said water collecting pan is sink-like and has vertical side, rear and front walls, a plumbing panel extending above said rear wall on which said mixing valve is mounted with a manual operating knob extending therefrom for said accessibility, an outlet fitting mounted on said panel connected to the output of said mixing valve, a flexible pipe interconnecting said outlet fitting with said first mentioned 4-way coupling, and a quick detachable coupling associated with said flexible pipe to disconnect said water spray assembly from said panel.
