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.

A device for being gripped by a human hand and responding to the squeezing thereof by said hand, said device comprising a substantially conically shaped hollow chamber, a hollow bellows, an orifice having one end in communication with said bellows, and the other end in communication with said chamber, a handle means connected to said conical chamber and forming a closed space between the handle means and conical chamber, said space being of a size sufficient to retain a hand in proximate gripping location to said chamber even though the hand is not actually gripping said chamber, said chamber being capable of retaining an indicator liquid therein, said chamber having sufficiently flexible walls such that when gripped and squeezed by said hand with sufficient force, a liquid retained therein will flow from said chamber through said orifice and into said bellows in an amount and to a degree proportional to the amount of force applied by said hand.
