US 20070118194 A1Abstract
A therapy system for therapeutically treating a desired region of the body includes a fluid reservoir, a heat transfer pad, and first and second fluid circulation lines. The heat transfer pad includes a first pad port, a bladder, and a second pad port. The first fluid circulation line is connectable to the first pad port for withdrawing heat transfer fluid from the fluid reservoir and delivering it to the heat transfer pad. The second fluid circulation line is connectable to the second pad port for withdrawing heat transfer fluid from the heat transfer pad and delivering it to the fluid reservoir. The heat transfer pad additionally includes a pad flowpath adjustment member positioned in the pad flowpath to adjust the system resistance to flow. The adjusted system resistance to flow fixes the desired treatment temperature of the heat transfer pad in response to the heat transfer fluid circulating through the pad flowpath. The desired treatment temperature is correlated to the body region being treated. Images(6) Claims(25)

In sum, the individual adjusted resistances to flow of the heat transfer pads 12 a, 12 b, 12 c, 12 d and correspondingly the system adjusted resistances to flow and the desired treatment temperatures of the non-ambient temperature therapy systems 10 a, 10 b, 10 c, 10 d are fixed to correspond with the specific requirements of the desired treatment application. Method of Operation An embodiment of a method of operating the non-ambient temperature therapy system 10 a is described hereafter with further reference to the drawings. It is understood that the operating method described hereafter applies generally to operation of the non-ambient temperature therapy systems 10 b, 10 c, 10 d as well. The method is initiated by a series of set-up steps, wherein the heat transfer pad 12 a is selected by the user as a function of the desired treatment application for a knee or shoulder treatment application. The heat transfer pad 12 a is then mounted on the skin of the desired body region of the patient where non-ambient temperature treatment is desired, which in the present case is the knee 68. An additional thin padding material, such as a soft cloth, may be placed on the skin between the bladder 34 a and the skin for the comfort of the patient. Mounting the heat transfer pad 12 a on the knee 68 is typically effected by wraps (not shown) which are permanently attached to the heat transfer pad 12 a or which are separately provided. The configuration of the heat transfer pad 12 a renders it readily and fully conformable to the contours of the knee 68 of the patient on which it is mounted. A plurality of slits 70 are formed in the heat transfer pad 12 a which enhance conformance to the knee 68. The configuration of the heat transfer pad 12 a enables a large fraction of the pad surface area to contact the knee 68 and advantageously facilitates heat transfer between the heat transfer pad 12 a and the knee 68. A charge of heat transfer fluid is placed in the fluid reservoir 14 via the opening 24. The heat transfer fluid is preferably a liquid and the volume of the heat transfer fluid charge is preferably several times the volume of the heat transfer pad 12 a. A preferred heat transfer fluid for a low temperature treatment is cold water. Solid ice can also be charged to the fluid reservoir 14 with the cold water to produce ice water for the low temperature treatment. A preferred heat transfer fluid for a high temperature treatment is hot water. The charged fluid reservoir 14 is positioned proximal the patient and the pump 20 is submersed in the heat transfer fluid within the fluid reservoir 14. The lid 26 is placed over the opening 24 with the first and second circulation lines 16, 18 extending from the fluid reservoir 14. The power line 56 of the pump 20 is connected to a source of electrical power. Once the heat transfer pad 12 a is mounted on the knee 68 and the pump 20 is operatively positioned, the couplings 38 a and 42 and the couplings 40 a and 44, respectively, are locked together to close the joint 46 and complete the set-up steps. The resulting non-ambient temperature therapy system 10 a is in an assembled state and in a condition for operation. Operation of the system 10 a is initiated by powering up the pump 20, preferably by means of an on/off power switch (not shown) mounted on the power connector 58 or simply by connecting the power line 56 with the wall outlet 54 and the power connector 58. The pump 20 withdraws the heat transfer fluid from the fluid reservoir 14 and drives the fluid through the first fluid circulation line 16 into the heat transfer pad 12 a, thereby inflating the bladder 34 a. The pump 20 circulates the heat transfer fluid through the internal flowpath of the bladder 34 a, causing the temperature of the heat transfer pad 12 a to drop to the desired treatment temperature in the case of a low temperature treatment and in turn causing the transfer of body heat from the patient to the pad 12 a by a heat transfer mechanism. In the case of a high temperature treatment, the heat transfer fluid causes the temperature of the heat transfer pad 12 a to rise to the desired treatment temperature and in turn causes heat to be transferred from the pad 12 a to the body of the patient by a heat transfer mechanism. In either case, the heat transfer fluid is withdrawn from the heat transfer pad 12 a after circulating therethrough and is returned to the fluid reservoir 14. The withdrawn heat transfer fluid mixes with the relatively large volume of heat transfer fluid remaining in the heat transfer reservoir 14, which functions as a heat sink, essentially reversing any temperature increase or decrease in the withdrawn heat transfer fluid due to heat transfer with the body. The pump 20 is operated continuously as long as treatment is desired, thereby providing continuous steady-state circulation of the heat transfer fluid between the fluid reservoir 14 and heat transfer pad 12 a for the duration of the treatment. Operation of the system 10 a is terminated by simply shutting off the electrical power to the pump 20. While the forgoing preferred embodiments of the invention have been described and shown, it is understood that alternatives and modifications, such as those suggested and others, may be made thereto and fall within the scope of the invention.
