Abstract:
1. A bio-signal analyzer, comprising: a pair of air cushions each having an air bag formed by sealing except an air inlet/outlet port and a resilience applying member, which applies resilience in an expansion direction to the air bag when air is exhausted from the inlet/outlet port by pressing with a load, and which allows air to enter the air bag through the inlet/outlet port accompanying decrease of the load, the air cushions being incorporated in portions supporting a vicinity of a lumbar region of a person in a human body support means; an air pressure measuring instrument connected to the inlet/outlet port of each of the air cushions to detect an air pressure variation in each of the air cushions caused by a human bio-signal; and an analyzing means that receives an electric signal of the air pressure variation in each of the air cushions detected by the air pressure measuring instrument to analyze a human condition, wherein each of the air cushions is disposed at one of positions corresponding respectively to left and right iliocostalis lumborum muscles of the person, in a substantially vertically long state along the respective iliocostalis lumborum muscles, and has a length such that an upper end thereof is set at least at a height corresponding to a lower face of a human diaphragm, and wherein the resilience applying member includes a three-dimensional solid knitted fabric which is accommodated in the air bag and which applies resilience to the air bag from inside.
