Description

  The present invention relates to a bedding shape measuring apparatus that is interposed between a subject and a bedding and measures the shape of the bedding on which the body is placed when the subject's body is placed on the bedding.

  Measurement of the shape of the bedding when the subject's body is placed has been conventionally performed. By acquiring the shape data of the bedding when the subject is placed, it is possible to provide bedding more suitable for the subject. Japanese Patent Application Laid-Open No. 2003-130634 describes a measuring method and a measuring device for the shape of a sinking bedding. This measuring apparatus includes a sensor for measuring the amount of subsidence, and a computer connected to the sensor via an interface unit and an AD conversion board.

  The sensor includes a reference joint piece and a plurality of joint pieces arranged to extend from the reference joint piece in a predetermined direction. One joint piece is connected to the reference joint piece in a refractive manner, and each of the other plurality of joint pieces is connected to the adjacent joint piece in a refractive manner. A pressure detection sensor is fixed to the upper surface of each joint piece. Each joint piece incorporates an angle sensor that detects a refraction angle with respect to an adjacent joint piece.

  The detected refraction angle and pressure data are transmitted to a computer. The computer graphically displays the shape and body pressure curve of the bedding on which the body of the subject is placed from the received refraction angle and pressure data. The reference joint pieces described above are arranged on the head side of the subject, and a plurality of each joint piece is arranged from the reference joint piece toward the foot side of the subject. The computer displays the shape of the bedding in a graph from the refraction angle of the joint piece with respect to the joint piece on the reference joint side.

JP 2003-130634 A

  In the measurement apparatus described above, the shape of the bedding is measured from the refraction angle of another joint piece with respect to one joint piece. However, since each of the plurality of joint pieces is provided continuously from the reference joint piece, if a detection error of the refraction angle occurs in one joint piece, the detection error is included in the shape data obtained from the other joint pieces. Also affects. Accordingly, an incorrect shape may be displayed due to a detection error of one joint piece, and there is a problem that the shape cannot be measured with high accuracy. In addition, since the angle sensor is likely to deteriorate over time when the measuring device is used for a long period of time, there is room for improvement in terms of the durability of the sensor.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a bedding shape measuring apparatus capable of measuring the shape with high accuracy and enhancing the durability.

By measuring the distortion of the base, the shape of the bedding can be measured with high accuracy. The strain gauge can obtain a measurement result with higher accuracy than a potentiometer or an angle sensor. In addition, the strain gauge is affixed to the opposite side of the second base on which the body is placed, and the strain gauge itself can withstand multiple bends. However, it is possible to make it difficult to cause deterioration over time. Therefore, durability of the bedding shape measuring apparatus can be enhanced.

  The bedding shape measuring apparatus may include a pressure sensor attached to the second base opposite to the first base, and a first elastic member that covers the pressure sensor. In this case, the pressure sensor is attached to each second base, so that the body pressure distribution applied to the bedding can be measured by the bedding shape measuring apparatus without using a dedicated device for measuring the pressure. Moreover, a pressure sensor can be protected by a 1st elastic member by providing the 1st elastic member which covers a pressure sensor. Furthermore, since the body of the subject is placed on the pressure sensor via the first elastic member, the uncomfortable feeling to the subject can be reduced. That is, since it is possible to prevent the hard part from hitting the body of the subject, the comfort of the bedding shape measuring apparatus can be improved.

  Moreover, the bedding shape measuring apparatus may include a second elastic member mounted on the second base. In this case, by providing the second elastic member on the second base on which the body is placed, the second base can be protected and the cushioning property of the bedding shape measuring apparatus can be enhanced. Therefore, by using the second elastic member between the body of the subject and the second base, the comfort of the bedding shape measuring apparatus can be further improved.

The standard of wireless communication between the computer 23 and the AD conversion board 22 is, for example, Bluetooth (registered trademark), but may be a communication standard other than Bluetooth (registered trademark). The computer 23 may be connected to the AD conversion board 22 by wired communication.

  The computer 23 may be, for example, a personal computer or a terminal device such as a tablet or a mobile terminal. The computer 23 receives from the AD conversion board 22 the shape data of the pillow 2 and the mattress 3 by the strain gauge 18 and the pressure data to the pillow 2 and the mattress 3 by the pressure sensor 19 as digital signals. That is, the computer 23 receives the digital data from the AD conversion board 22 to acquire the strain value detected by each strain gauge 18 and the pressure value detected by each pressure sensor 19.

In the example of FIG. 6, the vertical axis indicates the height of the upper surface of the pillow 2 and the mattress 3 and the magnitude of the pressure, and the horizontal axis indicates a graph indicating the displacement of the pillow 2 and the mattress 3 on the display 23a. In this graph, the side where the displacement value on the horizontal axis is small (left side) indicates the head side (the pillow 2 side), and the side where the displacement value on the horizontal axis is large (right side) indicates the foot side.

  As shown in FIG. 6, the computer 23 displays the shape data as a curve B and displays the pressure data as a region A protruding upward from the curve B. This indicates that pressure is applied to the location of the displacement where the region A exists, and no pressure is applied to the location of the displacement where the region A does not exist (the body is floating from the bedding). By this display method, the shape and pressure distribution of the pillow 2 and the mattress 3 can be easily grasped at a glance, and the sinking state of the pillow 2 and the mattress 3 can be easily grasped at a glance.

The strain gauge 18 can obtain a measurement result with higher accuracy than a potentiometer or an angle sensor. Further, since the strain gauge 18 is affixed to the opposite side of the second base 17 on which the body is placed, and the strain gauge 18 itself can withstand a plurality of bendings, the bedding shape measuring apparatus 1 is long.

Therefore, by attaching the pressure sensor 19 to each second base 17, it is applied to the pillow 2 and the mattress 3 by the bedding shape measuring apparatus 1 without using a dedicated device for measuring pressure (for example, ergo check). Body pressure distribution can be measured.

  In addition, by providing the first elastic member 14 that covers the pressure sensor 19, the pressure sensor 19 can be protected by the first elastic member 14. Further, the body of the subject is placed on the pressure sensor 19 via the first elastic member 14. Therefore, since it is possible to prevent the hard part from hitting the body of the subject, it is possible to reduce a sense of discomfort to the subject. Therefore, the comfort of the bedding shape measuring apparatus 1 can be improved.

  The bedding shape measuring apparatus 1 includes a second elastic member 15 mounted on the second base 17. Therefore, by providing the second elastic member 15 on the second base 17 on which the body is placed, the second base 17 can be protected and the cushioning property of the bedding shape measuring apparatus 1 can be enhanced. . Therefore, by interposing the second elastic member 15 between the body of the subject and the second base 17, it is possible to more reliably suppress the hard portion from hitting the body of the subject.
