A powered scrub brush having a power head module, a brush head module, and n extension shaft module. The power head module includes a positive-displacement motor and a flow-control valve. The motor may be coupled directly to the brush head module or indirectly through one or more extension shaft modules. The power head module has a liquid discharge port that is connected to a liquid discharge tube on the extension shaft module that in turn is connected to a liquid sprayer having a nozzle on the brush head module. Mechanical power is transferred from the motor to the brush via an output shaft on the motor, a flexible shaft in the extension shaft module, and a shaft in the brush head module on which the brush is removably mounted. The powered scrub brush is manually operated by regulating a flow-control valve that is connected between a pressurized water source and an inlet port on the motor. As pressurized liquid flows through the motor, the brush will rotate and liquid will be discharged via the nozzle. In an alternate embodiment, the brush is eccentrically mounted for orbital motion. In this version, a counterweight provides dynamic balance.

A soft goods type foldable, wrappable sleeve orthopedic cast immobilizes and conforms to the shape and configuration of a limb, or other part of the anatomy. The soft-goods type cast assembly is initially specially formed or configured to specifically fit a selected portion of the anatomy of a patient. The cast conforms to the anatomy through the use of airtight and moisture-proof pouches which encapsulate either (1) open cell or fiberglass matrices impregnated with a water-activated hardenable pre-polymer, or (2) the entire assembly. After the tightening of the cast around the limb, the application of water activates the urethane polymer which conforms to the configuration of the limb encased. Supplemental bendable ribs may be employed to splint the limb prior to activation of the hardenable material. The soft goods type cast is held in place by straps, and may be removed or adjusted by releasing or tightening the straps. The splinting elements may be removed and replaced. An inlet duct may have a capsule in it with some of the chemical material which aids in polymerization of the urethane. A venting duct may also be provided to permit the escape of air or gases. The water activated pre-polymer material may include two isocyanate pre-polymers of significantly different viscosities and equivalent weights.
