Description

  The present invention relates to a sleeping posture measuring sensor and a sleeping posture measuring device for detecting the posture and body pressure of a human body at the time of sleeping.

  In recent years, especially in developed countries, the average life expectancy of humans has continued to increase. This is because external factors such as advances in science and technology and medical technology and enhancement of nursing care services have contributed significantly, and the proportion of people who are always healthy is not at the same level as the rate of increase in average life expectancy. Absent.

  In other words, even though it is not healthy, it is becoming a society that can live longer due to external factors, but because everyone wants to stay healthy and live longer, the improvement of internal factors that seek to review their own lifestyle can be improved Become a topic.

  In addition, the number of developed countries suffering from insomnia due to mental stress caused by the management society against physical affluence is increasing, accounting for about one-third of the time people spend their lives. There is a growing interest in “sleep”.

  In addition, people with low back pain, shoulder pain and the like are seeking bedding that does not worsen the symptoms during sleep, and further bedding that can improve symptoms by sleeping.

  Thus, as interest in sleep increases, the number of people who want bedding such as pillows and mattresses that are optimal for themselves as tools for obtaining healthy sleep is increasing, and development by bedding manufacturers is underway.

  In bedding development, the posture and body pressure of the human body at bedtime are obtained as quantitative data, and based on this, highly functional bedding is developed, and multiple beddings classified according to physique such as height and weight are prepared. It is possible.

  Also, in stores that sell bedding, in order to provide customers with optimal bedding in a short time, if they can measure and evaluate the sleeping posture and body pressure of customers in the store, prepare according to the physique The bedding suitable for the customer can be selected and provided from the provided bedding.

  In this way, not only bedding development but also a device that can be easily measured in a store or the like is demanded. For example, a sinking measuring device according to Patent Document 1 is disclosed, and sinks on a mattress or other bedding. The measuring device is placed, and the subject is placed on a sleeping posture so that the shape and pressure of the bedding when the person sleeps can be measured.

  Specifically, the subsidence measuring device includes a subsidence amount measuring sensor and a pressure detection sensor in each joint piece, and a plurality of joint pieces having a predetermined length are flexibly connected to each other. It is comprised so that the bending angle and pressure which are made between may be detected.

  However, the subsidence measuring apparatus according to the present technology follows the angle change in the vertical direction because each joint piece is formed in a band shape by a connecting portion made of a pivot connection structure in which the axis is oriented in the horizontal direction. However, when sleeping on a bedding such as a mattress, the movement of each joint piece cannot follow the body pressure distributed vertically and horizontally, that is, the movement of the joint piece that connects the joint pieces other than the vertical direction of the adjacent joint pieces Therefore, it is difficult to accurately measure the posture at bedtime.

  In addition, a sinking measuring device placed between a bedding such as a mattress and a human body during measurement is to prevent movement of individual joint pieces other than the vertical direction even if the mattress has elasticity. In addition, since the excessive load is applied by the load of the human body to the joint portion of the joint piece that is originally intended to change the angle according to the shape of the human body, there is a problem that the joint portion is easily damaged.

  Also, if at least one of the two sensors arranged on each joint piece is damaged, it is necessary to remove the joint piece by removing the pivot from the two connecting parts in the front and rear, and reattach the joint piece having a normal sensor Therefore, handling at the time of failure becomes complicated.

  In addition, the joint piece can be easily extended in the longitudinal direction by the connecting part, but it cannot be arranged in a staggered manner or a plurality of rows can be integrally arranged in parallel, and the measurement location can be flexibly changed. Can not do it.

  Finally, an example of handling of the sleeping posture measuring apparatus A according to the present embodiment will be briefly described.

  It is assumed that the information processing apparatus 63 has previously acquired the positional relationship in the horizontal direction of each sensor unit 15 of the sleeping posture measurement sensor 1 as data.

  First, as shown in FIG. 11, the horizontal piece 52 of the sleeping posture measuring device A is inserted under the mattress S1 from the front of the mattress S1 on which the pillow S2 is placed, and the movable portion fixing knob 41 is operated to sleep. The height T of the measurement sensor 1 is adjusted to the height of the pillow S2, and the sleeping posture measurement sensor 1 is placed in the longitudinal direction of the mattress S1.

  Next, after connecting the USB cable 60 extending from the signal processing unit 58 to the information processing device 63, the information processing device 63 is started up to display and analyze the sleeping posture, the body pressure distribution at the time of sleeping, and the like. Start a program such as a sleeping posture measurement program.

  The data requested by the information processing device 63 is as follows, and the data is input from the keyboard 64 of the information processing device 63.

  The input data is first the height T of the sleeping posture measurement sensor 1, and the numerical value of the height adjustment scale 36 where the lower end surface 44 of the guide portion 42 is located, that is, the height of the mattress S1 and the height of the pillow S2. Enter the combined value.

  Next, the position of the foremost sensor unit 15a where the flexible base material 2 of the sleeping posture measuring sensor 1 is flat on the mattress S1 (rank of the sensor unit 15 from the front: “11th”) is input. Thus, the information processing device 63 subtracts the height from the height T of the sleeping posture measuring sensor 1 to the frontmost sensor unit 15 that is flat, and similarly, the height of the subsequent sensor unit 15 that is flat is also calculated. Subsequent subtraction is performed, and all are added together to calculate an average value to obtain the thickness of the mattress S1.

  The reason why the height can be calculated based on the position of the sensor unit 15 in this way is based on the inclination detection function by the acceleration sensor provided in the sensor unit 15 and the horizontal position data of the sensor unit 15, and the thickness of the pillow S2. Is naturally calculated.

  In this manner, the information processing apparatus 63 can recognize the initial state of the pillow S2 and the mattress S1 before the subject H takes a sleeping position on the mattress S1, and the subject H takes the sleeping posture. The sinking amount and body pressure of S1 and pillow S2 can be acquired and displayed.
