Abstract: A simplified device to provide air circulation under bed-ridden patients which comprises a small thin flexible plastic pad having a plurality of flexible plastic tubes embedded or encased therein, said tubes comprising a distributer tubing and a plurality of closed end discharge tubes feeding off therefrom. The discharge tubes all contain a plurality of upwardly extending openings therein, while the distributer tubing is connected to a source of low pressure air. In use, the pad, covered with a replaceable, sterile mesh fabric cover is placed under a patient and air is forced out of said openings to circulate under the patient minimizing the formation of bed sores on such patients.
