## Indications for Use

The intended use of the device is to aid in adding moisture to necrotic areas in order to aid in the debridement of wounds, to aid in the relief of pain and discomfort, to aid in the cleansing of open wounds, and as a form of physical therapy for certain types of pathologies.

## Device Story

Powered sitz bath for home use; supports patient in chair with backrest, armrests, seat, and frame.

Soft polyethylene construction prevents skin pressure. Provides hydrotherapy to aid wound debridement, cleansing, and pain relief; reduces need for hospital transport.

## Clinical Evidence

No clinical data; bench testing only.

## Technological Characteristics

Materials: soft polyethylene. Principle: air-blower driven water agitation via hydro-pad ports. Form factor: chair with removable arm frames, suction cups, and stable bar for bathtub mounting. Energy source: electric blower motor. Connectivity: none.

## Regulatory Identification

The Hydro-pad is connected at the base of the Chair and the posterior opening of the Hydro-pad connects to a hose(typically rubberized tubing) which is connected to a blower motor which exerts a powerful pressure of air circulating through the ports of the Hydro-pad.

Streams of water jet through the ports causing a swirling motion of the water in which the Hydro-pad is immersed. The Chair is also
