A biomedical apparatus for monitoring and evaluating physical properties associated with a biologic or biomedical system is provided. When adapted to monitor and evaluate pressure at any interface between two abutting surfaces, the biomedical apparatus includes a sensor pad including at least one pressure sensor that is adapted to be disposed between the two surfaces to measure pressures exerted on one surface by the other surface, and generate data representative of measured pressures. At least one transducer is provided, with one transducer being in communication with each sensor for generating output signals representative of pressures measured by the sensor. Electronic circuitry further is provided that includes data processing circuitry for processing output signals generated by the transducer and generating pressure data based upon pressures measured by the sensor. A display is electrically connected to the data processing circuitry for visually displaying information representative of pressure data generated by the data processing circuitry. The electronic circuitry and transducers are disposed in a hand-held housing, and the display is mounted on the housing. Tubing extending between the sensor pad and the housing connects each sensor to one transducer. A power source disposed inside the housing for supplying power to the electronic circuitry. In the preferred embodiment, three hydraulic pressure sensors having quadfoliate configurations are arranged on the sensor pad to provide sufficient surface area to cover a bony prominence of an individual resting against a surface.

Biomedical apparatus

A modular backrest system for a wheelchair is removably attached to backrest posts of the wheelchair. The backrest system includes a back support that provides a surface against which the back of a wheelchair user rests, and a support chassis mounted to the back support for supporting the back support at a desired incline with respect to the posts, and at a desired seat depth with respect to the seat. An attachment assembly is further included that is operably connected to the support chassis at two locations and to the posts to allow the support chassis and back support to be readily removed from or attached to the chair. The particular back support employed in conjunction with the support chassis is based upon the support needs of the wheelchair user. One embodiment of the back support includes a backing plate, and a cushion or insert attached to a forwardly presented face of the backing plate against which the back of the individual rests when sitting on the seat. Another embodiment of the back support includes a plurality of pads adjustably attached to support tubes extending upwardly from the support chassis. Each pad is attached to at least one of the support tubes at a desired location by an elbow joint that permits forward and rearward movement and side-to-side movement of the pad. Each pad is attached to the elbow joint by a ball and socket joint that permits rotational movement of the pad with respect to the second member.
