DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

An arthritic hand or foot treatment system 10 according to the present invention is shown in FIG. 1.
The arthritic hand or foot treatment device 10 includes an air treatment device 12, a flexible hose 14, a hand or foot treatment device 16, and a flexible bag 18.
The air treatment device 12 includes a bottle-shaped air treatment chamber 20 having an upper threaded end 22 and a lower open end 24. The air treatment chamber 20 is supported by a base stand 26. For example, the air treatment chamber 20 can be made of a plastic by a blow molding process the same or similar to a two-liter beverage bottle or container. The plastic material can be polyethylene teraphalate (PET), polyethylene, polypropylene, polyvinyl or some other suitable resin or synthetic resin material.
The air treatment chamber 20 is provided with an electric powered blower fan unit 28 supported by the inside wall of the air treatment chamber 20. The fan unit 28 draws in air from the lower open end 24 of the air treatment chamber 20, and pressurizes the air above the fan 28. A one-way valve 30 is provided in the neck portion 20 a of the air treatment chamber 20. At least one electric powered heating coil 32 is provided above the fan unit 28, and supported by the inner wall of the air treatment chamber 20. A drying layer 34 is provided at the bottom of the air treatment chamber just above the lower open end 24 of the air treatment chamber 20. For example, the drying layer 34 can comprise a layer of anhydrous crystals contained by an upper and lower screen 36, 38.
The lower open end 24 of the air treatment chamber 20 is also provided with air vents 42 through the wall thickness of the air treatment chamber 20 to ensure that an adequate amount of air enters the lower open end 24 of the air treatment chamber 20. In addition, the air treatment chamber 20 is provided with a thermostat 44 for controlling the temperature of the air above the heating coil 32.
The flexible hose 14 is provided with threaded ends 14 a and 14 b to connect with the air treatment device 12 and hand or foot treatment device 16, respectively. The flexible hose 14 can be made of plastic or rubber, and preferably is reinforced with a plastic cord or metal spring or rings embedded within the walls of the flexible hose 14. In addition, one or more securing devices such as a rubber ring, elastic band, wire, metal band can be used to further secure the threaded ends 14 a, 14 b to the air treatment device 12 and hand or foot treatment device 16, respectively.
The hand or foot treatment device 16 is provided with a bottle-shaped hand or foot treatment chamber 48 having a threaded end 50 and open end 52. The hand or foot treatment chamber 48 is provided with a thermostat 54 to control the temperature of the air within the hand or foot treatment chamber 48, and a one-way pressure relief valve 56. The hand or foot treatment chamber 48 is provided with a peripheral groove 58 to connect with the flexible bag 18 to be described in detail below.
The hand or foot treatment chamber 48 is preferably made of clear see through plastic material. For example, the hand or foot treatment chamber 48 is a plastic blow-molded bottle, the same or similar to a 2 liter beverage bottle or container, with the bottom cut open. The plastic material can be PET, polyvinyl chloride, polyethylene, polypropylene, or some other suitable resin or synthetic resin material.
The flexible bag 18 is provided with a pair of opposite open ends 18 a, 18 b. For example, the flexible bag 18 can be made of a clear see through plastic material the same or similar to that used for making plastic garbage bags. Further, the flexible bag can be from a continuous plastic plenum, and then cut to length.
The open end 18 a is connected to the hand or foot treatment device 16. Specifically, the open end 18 a is fitted around the periphery of the hand or foot treatment chamber 48 over the peripheral groove 58 and then a securing device 60 (e.g. metal ring with screw tighten, elastic band, elastic ring, hose clamp, wire) secures the open end 18 a of the flexible bag 18 into the peripheral groove 58 of the hand or foot treatment chamber 48 of the hand or foot treatment device 16. The opposite open end 18 b fits over the arm or leg of the person being treated, and then one or more securing devices 62 (e.g. hook and loop type fastener, Velcro strap, elastic band, elastic ring) is used to tightly secure the open end 18 b to the outer surface of the arm or leg.
The arthritic hand or foot treatment device 10 can come as separate units (e.g. air treatment device 12, flexible hose 14, hand or foot treatment device 16, and flexible bag 18), for example, in a single container, and then assembled together when using. Alternatively, the arthritic hand or foot treatment device 10 is fully assembled and stored in container during non-use and then removed from the container for use. The arthritic hand or foot treatment device 10 is preferably portable, highly portable, lightweight and inexpensive to promote home or office (work) use. In a preferred embodiment, the parts or components of the arthritic hand or foot treatment device 10 are made of inexpensive materials and are inexpensive to manufacture and make.

Operation

The arthritic hand or foot treatment device 10 is assembled by connecting the flexible hose 14 to the air treatment device 12 and the hand or foot treatment device 16. The flexible bag 18 is connected to the hand or foot treatment device 16.
During use, the flexible bag 18 is connected around the arm of leg of the person receiving treatment using one or more securing devices 62. The electric fan 28 is turned on (e.g. using a switch or plugging the unit into a conventional wall socket). Further, the at least one heating coil 32 is energized to heat the air downstream of the fan unit 28. The thermostat 44 senses the temperature of the air above the at least one heating coil 32, and turns the heating coil 32 on and off to maintain a preset air temperature above the heating coil 32.
The air entering into the air treatment chamber 20 is dried (i.e. moisture is removed from the air stream) by the drying layer 34. Due to the buildup of pressure above the fan unit 28 during operation thereof, the one-way valve 30 opens to release pressurized, heated and dried air into the flexible tube 14, and then into the hand or foot treatment device 16. The hand or foot treatment chamber 48 forms a single treatment chamber with the flexible bag 18. When air pressures build up within the hand or foot treatment chamber 48, the one-way pressure relief valve 56 opens to maintain the pressure within the hand or foot treatment chamber 48 at a predetermined level. Further, the thermostat 54 senses the temperature within the hand or foot treatment chamber 48, and controls the fan unit 28, heating coil 32 and/or valve 30 to maintain the temperature within the hand or foot treatment 48 at a preset level. In this manner, the hand or foot of the user is subjected to pressurized air, heated air and dried air for a period of time significantly aleeving the ailments and pain associated with an arthritic condition. For example, the person's hand or foot is treated for ten to twenty minutes using the hand or foot treatment system 10 according to the present invention.
