The biological information (body movement, weight, heart rate and respiration) of the person 12 is detected.

  The intersection of the warp and weft of the woven fabric constituting the biological information detection sensor 2 forms a kind of condenser by sandwiching the conductive fibers between the non-conductive fibers, so that pressure is applied to the biological information detection sensor 2. When this happens, the capacitance of this capacitor changes. Therefore, the biological information detection sensor 2 can detect a change in pressure as a change in capacitance. The biological information detection sensor 2 can detect the pressure distribution. Therefore, the biological information detection sensor 2 can detect the distribution of the weight of the occupant 12 who joins the bed 1.

(Position of the person in bed)
A procedure for specifying the posture of the bed person 12 in the bed 1 will be described with reference to FIG.

  As shown in FIG. 3A, an XY coordinate system is set in which the longitudinal direction of the bed 1 is the X axis, the lateral direction is the Y axis, and the center position of the bed 1 is the origin O (0, 0). .

  When the occupant 12 lies on the bed 1, the biological information detection sensor 2 detects a pressure change due to the weight of the occupant 12.

  Next, the weight distribution identification program 21 analyzes the pressure change detected by the biological information detection sensor 2 and identifies the weight distribution of the bed 1 as shown in FIG.

  As described above, the biological information detection sensor 2 can detect pressure changes due to respiration and heartbeat of the bed person 12. Therefore, the chest position specifying program 22 can specify the position where the pressure change due to respiration is most prominently detected on the biological information detection sensor 2 as the chest position. Hereinafter, this is indicated as A (X1, Y1) in the XY coordinate system. The biological information detection sensor 2 also detects a pressure change due to a heartbeat, but since the generation periods of respiration and heartbeat are different, both can be separated.

  The chest position A (X1, Y1) can be obtained by the following procedure. That is, when an X′-Y ′ coordinate system having the origin at the center position of the biological information detection sensor 2 as shown in FIG. 3C is set, the chest position A (X1, Y1) based on the X′-Y ′ coordinate system. Is obtained by the following equation.

  Here, BX ′ is the length in the longitudinal direction of the biological information detection sensor 2, and BY ′ is the length in the short direction of the biological information detection sensor 2. Pa, Pb, Pc, Pd are pressures detected at the four corners a, b, c, d of the biological information detection sensor 2.

  If the coordinates (X1 ′, Y1 ′) of the chest position A obtained by the equations (1) and (2) are converted into the XY coordinate system, the chest position A (X1, Y1) based on the XY coordinate system is obtained. can get.

  Next, the body position specifying device 8 specifies the head position and the leg position of the bed person 12.

  First, the position specifying program 24 specifies the positions of both ends B and C (see FIG. 3B) in the length direction of the weight distribution. Here, the length direction of the weight distribution is two points belonging to the region where the weight of the bed 12 of the bed 1 is added, and the direction of the line segment connecting the two points where the distance between the two points is maximum. The both ends of the line segment are defined as both ends B and C in the length direction of the weight distribution. Thereafter, both ends B and C are displayed as B (X2, Y2) and C (X3, Y3) using the XY coordinate system.

  Next, the distance calculation program 25 calculates the distance between the chest position A and the position B at one end, and the position between the chest position A and the position C at the other end. When the distance between the chest position A and the end B is L1, and the distance between the chest position A and the end C is L2, L1 and L2 are obtained from the following equations.

  One of the end B and the end C is the head position, and the other is the leg position. The head position and the leg position are determined by the magnitudes of the distances L1 and L2. In other words, if L1 <L2, the end B is close to the chest position, so it is specified as the head position, and the end C is specified as the leg position. In the case of L1> L2, the end B is specified as the leg position, and the end C is specified as the head position.

  Moreover, since the biological information detection sensor 2 can also specify the position where the heartbeat of the in-bed person 12 is detected most prominently, this position may be set as the chest position of the in-bed person 12.

  If the weight distribution specifying program 21 calculates the center (center of gravity) of the weight distribution and executes the weight distribution specifying program 21 every predetermined time to detect that the center of gravity exceeds a predetermined threshold value, The body movement of the person 12 can be detected. The body movement is a body movement caused by the bedside person 12 turning over or jerking.
