PATIENT SUPPORT SYSTEM AND METHOD

摘要

A patient support system for a wheelchair is provided. At least a portion of the patient support system components form a no-air-loss patient support surface. At least one fluid pump can supply air pressure to a plurality of no-air-loss air cells, and at least one pressure release valve can release air pressure from the no-air-loss air cells. A computer can compare air pressure within the air cells to a desired air pressure set point and can modulate the air pressure by actuating the at least one fluid pump and/or the at least one pressure release valve to bring the air pressure within the air cells to a desired air pressure. After the initial air pressure adjustments are made and the desired air pressure is achieved, no further adjustments during the operation are able to be made by the computer so that the patient positioned thereon the patient support system will not be moved by the patient support system during an operation.

主权项

1. A patient support system for reducing the formation of bedsores on a patient, the system comprising:
a plurality of no-air-loss air cells, wherein at least a portion of the plurality of no-air-loss air cells form a no-air-loss patient support surface; at least one fluid pump coupled to the plurality of no-air-loss air cells; at least one pressure release valve coupled to the plurality of no-air-loss air cells; at least one pressure sensor coupled to the plurality of no-air-loss air cells; a computer having a processor, wherein the computer is coupled to the at least one fluid pump, the at least one pressure release valve and the at least one pressure sensor, wherein the at least one pressure sensor is configured to send a pressure signal to the computer representing the air pressure within at least a portion of the plurality of no-air-loss air cells, wherein the computer is configured to:
activate at least one of the at least one fluid pump and the at least one pressure release valve if the sensed air pressure differs from a desired air pressure set point; andclose the patient support system when the sensed air pressure within at least a portion of the plurality of no-air-loss air cells is within a predetermined tolerance of the desired air pressure set point in a loaded condition, wherein, when the patient support system in closed, no adjustments to the air pressure within the plurality no-air-loss air cells are subsequently made.
