MODULE TYPE PATIENF SUPPORTING DEVICE WITH LOW AIR LOSS AND AUTOMATIC PATIENT-TURNING AND ITS OPPRESSED POINT-REMOVING METHOD

摘要

PURPOSE: To obtain the patient supporting device of supporting the different site of a patient using the pressure of different bag bodies by providing the device with the plurality of a slender and inflatable bag bodies, a pair of the end portioned chambers of both end portions of the bag bodies, a pair of a middle chambers having a right pentahedral shape, and the first and second flow controlling passages for connecting the first and second end portioned chambers to the first and second middle chambers. CONSTITUTION: The plurality of a slender and inflatable bag bodies are provided on a patient supporting device, each bag body 34 provides the inside structure of a double chambers and the shape of the bag body 34 is rectangular. The end portioned chambers 46 are arranged in both end portions of each bag body, and the bag body of each double chambers has a pair of a middle chamber 54 arranged between the end portioned chambers, the each middle chamber is shaped as the pentahedron of a right-angled triangle and the one of the middle chamber is arranged on the upper portion of the other middle chamber. Each bag body has a pair of the flow controlling passage, and one passage makes the each of the end portioned chamber to communicate with acontiguous middle chamber. Each flow controlling passage is formed by the hole 64 of passing through a common web against the middle chamber and a contiguous end portioned chamber, and initially the end portioned chamber is filled by an air, and then faded away at last when the air is drawn out.
