ABSTRACT:
A device is provided which helps rehabilitate and exercise the hand. In doing so, it indicates the progress being made, thus providing positive mental reinforcement, encouraging further improvement in the rehabilitation process. The device, which is blow molded from translucent plastic, includes a hollow conically shaped chamber having formed integrally therewith a handle and a bellows device connected via an orifice to the chamber. Fluid of a chosen color is provided in the chamber. Upon squeezing, the fluid is ejected in proportion to the force applied from the chamber into the bellows, thereby giving the patient a visual, positive indication of his progress. A series of devices requiring progressively increasing squeeze forces may be formed by using different fluids, conduit sizes and/or wall thicknesses. This provides a system for full rehabilitation. The handle is so located that even in the earliest stages of rehabilitation where the patient may not be able to hold onto the device itself, the device will be held on the hand.
