Document Type and Number:
Japanese Patent JP3860927
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To evaluate a cushion mat for bedsore prevention based on a fixed reference.
SOLUTION: A plurality of through-holes 3 are orderly perforated on the upper surface plate 2' of a lower surface opened box 2 mounted on a base plate 1, freely vertically movable sliding rods 4 are fitted to the respective through-holes 3, vertical movement guides 5 communicating with the respective through-holes 3 are arranged on the lower surface of the upper surface plate 2' and the change of a voltage applied to the guides 5 by the vertical movement of the sliding rods 4 in contact with the guides 5 is measured. Then, electronic force balances 6 are arranged on the upper ends of the respective sliding rods 4 and the pressurizing surfaces 7 for the cushion mat of the same area as the pressure receiving surfaces 6' of the electronic force balances 6 are arranged on a lower end.
