DETAILED DESCRIPTION OF EMBODIMENTS
Referring to now to FIGS. 1-7, there is shown a therapeutic appliance 100 (see FIG. 4) embodying the present invention and generally comprising a hot and cold eye mask (see FIG. 1), a recirculating water system 3 (see FIG. 5 or 6) detachably connected to the eye mask, and a thermoelectric device 4 (see FIG. 4). The eye mask generally includes a water pack 1, a rigid covering 10 placed over the water pack 1, and a plurality of massaging fingers 21, 22 of different sizes.
With reference to FIGS. 2 and 3, the water pack 1 has a cavity 11 for containing a liquid. Each of the massaging fingers 21 or 22 has a vibrator 210, 220, a buffering base 212, 222 and a plurality of flexible ribs 211, 221.

The vibrators 210, 220 are disposed on the water pack 1 to excite the liquid in the water pack 1 for massaging a body portion to be massaged.
Specifically, the water pack 1 has one side 12 to be in contact with the body portion and the opposite side 13 on which the vibrators 210, 220 of the massaging fingers 21, 22 are mounted. Each of the flexible ribs 211, 221 has one end extending from a periphery of the buffering base 212, 222 and the other end attached to an internal wall surface of the water pack 1 such

4 that the ribs 211, 221 are arranged in a shape generally conforming to a contour of the vibrator 210, 220. With the buffering base 212, 222 and the flexible ribs 211, 221, each of the massaging fingers 21, 22 can provide a relatively small but comfortable massage to the user using the therapeutic appliance 100.
Preferably, a rigid covering 10 may be employed to be placed over the water pack 1 as well as the massaging fingers 21, 22 for protection.
More preferably, the covering 10 may be shaped to form a plurality of receptacles 101 receive the respective vibrators 210.
Referring to FIGS. 6 and 7, the recirculating water system 3 has a container 30, a conduit 5 connecting the container 30 and the water pack 1, and at least one cooling fan 6. The container 30 is divided into a first compartment 31 in which the liquid is stored, a second compartment 34 in which the eye mask can be stored when not in use (see FIG. 4 or 6), and a third compartment 32 in which the conduit 5 is partially disposed. The first compartment 31 is in communication with the chamber 11 of the water pack 1 via the conduit 5.
The thermoelectric device 4 is disposed in the first compartment 31 of the container 30 of the recirculating water system 3 for heating or cooling liquid circulating between the water pack 1 and the container 30. That is, the thermoelectric device 4 acts to achieve a preselected temperaturc for the liquid in the water pack 1. Moreover, a pump 7 is employed in the third compartment 32 for forcing the liquid to flow through the conduit 5 and between the first compartment 31 of the container and the cavity 11 of the water pack 1 so that the liquid is permitted to circulate between the container

5 30 and the water pack 1. Thus, heating or cooling of the liquid is accomplished by heating or cooling the liquid outside the eye mask and supplying the heated or cooled liquid to the water pack 1 by the conduit 5.
Safety for the user of the therapeutic appliance 100 is therefore enhanced by positioning the thermoelectric device 4 in the container 30, sufficiently isolated from the eye mask.
The cooling fan 6 is disposed in the third compartment 32 and is directed toward the conduit 5 for heat dissipation. Preferably, a plurality of vent holes 33 are defined in a wall of the third compartment 32 for circulation of air.
For ease of carrying, the container 30 of the recirculating water system 3 may be formed in a box-like carrying case, as depicted in FIG. 4 or 5. Flexibility for the user of the therapeutic appliance 100 is enhanced by removably connecting the recirculating water system 3 to the eye mask.
Referring now to FIG. 8, there is shown an alternate embodiment of the eye mask, which is similar to that of FIG. 3, except that in each relatively smaller massaging finger 25, a spring 252 is provided in lieu of the buffering base 212 and the flexible ribs 211 of each massaging finger 21. The spring 252 is interposed in between the associated receptacle 101 of the covering 10 and the associated vibrator 251 of the massaging finger 25. Similarly, the massaging fingers 25 can provide a comfortable massage to the body portion.
It is understood that the preferred embodiment of the present invention is applied for a "facial treatment" in which the water pack 1 of the therapeutic appliance 100 is placed on the face of the user. Alternately, in other

6 embodiments, such a technique can also be used if devices for other than the face of the user are constructed within the principles of the present invention.
For instance, an apparatus which is attached to the back of the user, as illustrated in FIG. 9, or the knee of the user, as illustrated in FIG. 10 can be employed.
