Embodiments for Carrying out the Invention

[0019] (Description of the Embodiment) Hereinafter, an example of an embodiment (example) of the spinal measurement device according to the present invention will be described with reference to the drawings.

[0020] Note that the present invention is not limited by the following embodiments. In addition, the components in the following embodiments include those that can be easily assumed by those skilled in the art, those that are substantially the same, and those within the so-called equivalent range. Furthermore, the components disclosed in the following embodiments can be combined as appropriate.

[0021] Note that in the drawings, since they are schematic views, the main parts are illustrated and the illustration of parts other than the main parts is omitted. Also, the upper side, lower side, left side, right side in FIG. 2, and the upper side, lower side, front side, rear side in FIG. 4 indicate the directions of the human body of the subject P.

[0022] (Description of the configuration of the embodiment) Hereinafter, the configuration of the spinal measurement device 1 according to this embodiment will be described. The spinal measurement device 1 according to this embodiment may be simply referred to as the "spinal measurement device 1" hereinafter. Here, the upper side, lower side, left side, right side, front side, and rear side in the spinal measurement device 1 correspond to the upper side, lower side, left side, right side, front side, and rear side of the subject P when the spinal measurement device 1 is measuring the angle of the spinal column SV of the subject P.

[0023] (Description of the spinal measurement device 1) As shown in FIGS. 1 to 4, the spinal measurement device 1 includes a main body member 2, a roller member 3, an angle sensor 4, a control unit 230, and display units 232, 233L, 233R, and 234. The spinal measurement device 1 can screen for scoliosis by measuring the angle of the spinal column SV of the subject P.

[0024] Normally, when viewed from the front, the spinal column has a straight shape up and down. However, in the case of scoliosis, the spinal column is curved to at least one of the left side or the right side and at the same time has a twisted shape. Therefore, by measuring the angle of the spinal column SV of the subject P with the spinal measurement device 1, scoliosis can be screened.

[0025] As shown in FIG. 4, the spinal column SV curves from the lower hip S to the upper neck E, curving from the front to the back and also from the back to the front. That is, in the median sagittal plane, the spinal column SV forms a concave-convex curve on the front side or the back side. As shown by the solid-line arrows in FIG. 4, the spinal column measuring device 1 measures the angle of the spinal column SV while moving along the spinal column SV that forms a concave-convex curve on the front side or the back side, from the hip S to the neck E.

[0026] (Description of the main body member 2) As shown in FIGS. 2 and 4, the main body member 2 moves along the spinal column SV of the subject P from the lower hip S to the upper neck E under the guidance of the roller member 3. As shown in FIGS. 1 to 4, the main body member 2 has a main body part 20, a handle part 21, and electronic device parts 22 and 23.

[0027] The main body part 20 has a hollow case structure and is composed of a resin member in this example. Note that the main body part 20 may be composed of a member other than the resin member. The upper end of the handle part 21 is attached to the center of the lower and front side portion of the main body part 20. The structure and constituent members of the handle part 21 are not particularly limited. Also, the handle part 21 may be detachable from the main body part 20.

[0028] The electronic device parts 22 and 23 are provided in the main body part 20. The electronic device parts 22 and 23 have a power supply board 22 and a control board 23.

[0029] (Description of the power supply board 22) As shown in FIG. 3, the power supply board 22 has an angle sensor 4, a first moving distance measurement part 221, a power supply control circuit part 222, a power supply part 223, and a USB port 224. The angle sensor 4, the first moving distance measurement part 221, the power supply control circuit part 222, the power supply part 223, and the USB port 224 are housed in the main body part 20.

[0030] (Description of the angle sensor 4) As shown in Fig. 4, the angle sensor 4 is disposed at the center of gravity point G of the spinal measurement device 1 in the main body member 2. When the main body member 2, i.e., the spinal measurement device 1, moves along the spinal column SV from the buttocks S of the subject P, which is the measurement start point, to the neck E of the subject P, which is the measurement end point, the angle sensor 4 detects the angle information of the spinal column SV and outputs the detected angle information to the control unit 230.

[0031] In this example, the angle sensor 4 uses at least one of a gyro sensor, an acceleration sensor, or an angular velocity sensor. In addition to the above sensors, the angle sensor 4 may be combined with a MEMS motion sensor, a geomagnetic sensor, etc.

[0032] As shown in Figs. 1, 2, and 4, the origin of the spatial coordinates is set to the center of the rotation part 30 of the roller member 3 described later, and is the measurement point M. The X-axis of the spatial coordinates is the rotation axis V of the roller member 3. The Y-axis of the spatial coordinates is the axis in the direction of the spinal column SV of the subject P and is the axis in the direction in which the main body member 2 moves along the spinal column SV of the subject P. The Z-axis of the spatial coordinates is the axis in the direction orthogonal to the spinal column SV of the subject P and is the axis orthogonal to the X-axis and the Y-axis. The angle sensor 4 and the measurement point M are relatively fixed. In this way, the angle sensor 4 detects the angle information around the three axes X, Y, and Z at the measurement point M and outputs it to the control unit 230.

[0033] When the angle sensor 4 detects the rotation information or inclination information of the spinal column SV of the subject P from the buttocks S to the neck E as angle information, in order to detect angle information such as which position of the spinal column SV has a large rotation or inclination, after starting the measurement, the information of the acceleration sensor built in the angle sensor 4 is integrated to calculate the moving distance from the buttocks S, and the position of the spinal column SV is linked to the rotation or inclination.

[0034] (Description of the first moving distance measurement unit 221) The first moving distance measurement unit 221 is disposed at a location on the upper part of the main body 20, closer to the right side than the center. An opening 200 is provided at a location corresponding to the first moving distance measurement unit 221 of the main body 20. The first moving distance measurement unit 221 faces the second moving distance measurement unit 33 described later through the opening 200 of the main body 20.

[0035] In this example, the first moving distance measurement unit 221 is an optical sensor or a magnetic sensor. The first moving distance measurement unit 221 receives light from a plurality of reflecting surfaces that are the second moving distance measurement unit 33 or magnetism from a plurality of magnets that are the second moving distance measurement unit 33, and non - contact detects the rotation speed of the roller member 3. Then, in the control unit 230 described later, the moving distance is calculated from the rotation speed of the roller member 3 detected by the first moving distance measurement unit 221 and the diameter of the rotation part 30 of the roller member 3 described later, and the main body member 2 moves along the spinal column SV from the buttocks S of the subject P, which is the measurement start point, to the neck E of the subject P, which is the measurement end point, to obtain the moving distance.

[0036] (Description of the power control circuit unit 222 and the power supply unit 223) The power control circuit unit 222 supplies the power from the power supply unit 223 to the control unit 230 described later. In this example, the power supply unit 223 is a dry battery. On the rear surface or the front surface of the main body 20, a cover 201 for replacing the power supply unit 223, which is a dry battery, is provided so as to be openable and closable. Note that the power supply unit 223 may be a rechargeable battery instead of a dry battery. When the power supply unit 223 is a rechargeable battery, power is supplied from the USB port 224.

[0037] (USB port 224) The USB port 224 is disposed in the left part of the main body 20. A port opening 202 is provided at a location corresponding to the USB port 224 of the main body 20. The USB port 224 transmits the angle data D acquired and output by the angle sensor 4 to other electronic devices, or supplies power to the power supply unit 223 in the case of a rechargeable battery. Note that the USB port 224 may not be provided.

[0038] (Description of the control board 23) As shown in FIG. 3, the control board 23 includes a control unit 230, a memory unit 231, display units 232, 233L, 233R, 234, an auditory notification unit 235 as a notification unit, and operation switches 236, 237, 238. The control unit 230, the memory unit 231, and the auditory notification unit 235 are housed in the main body unit 20. The display units 232, 233L, 233R, 234 and the operation switches 236, 237, 238 are provided in a portion below the cover 201 on the front surface of the main body unit 20. Note that the display units 232, 233L, 233R, 234 are provided at positions that are easily visible to a measurer such as a doctor or a technician in a state where the spinal measurement device 1 is measuring while moving between the buttocks S and the neck E of the subject P on the front surface of the main body unit 20.

[0039] (Control unit 230) The control unit 230 is composed of other elements including hardware such as a CPU (Central Processing Unit) and memory parts (ROM (Read Only Memory), RAM (Random Access Memory), non-volatile memory, etc.). The control unit 230 controls the entire spinal measurement device 1 by executing a control application program stored in the memory part.

[0040] The control unit 230 converts the angle information output from the angle sensor 4 into angle data D by applying a Madwick filter.

[0041] (Description of the memory unit 231) The memory unit 231 has an EEP memory. The memory unit 231 stores the angle data D output from the control unit 230 in the BUFF. In addition, the memory unit 231 stores the angle data D at the time of 0 correction of the angle.

[0042] (Description of the auditory notification unit 235) In this example, the auditory notification unit 235 is a buzzer that emits an electronic sound A which is a buzzer sound. As shown in the electronic sound A in Fig. 6, the auditory notification unit 235 sounds the electronic sound A at approximately 0.5 - second intervals after the spinal measurement device 1 starts the measurement. Fig. 6 is an explanatory diagram of a time chart showing the relative relationship between time T (unit: second), the state of the electronic sound A, and the spinal column SV from the buttocks S to the neck E of the subject P. Also, in Fig. 6, the buttocks S of the spinal column SV is the measurement start point, and the neck E of the spinal column SV is the measurement end point. Thus, when the main body member 2 moves along the spinal column SV from the buttocks S at the measurement start point to the neck E at the measurement end point of the spinal column SV, the auditory notification unit 235 sounds the electronic sound A at approximately 0.5 - second intervals.

[0043] In the electronic sound A of Fig. 6, the thick line indicates the state where the electronic sound A is sounding, and the thin line indicates the state where the electronic sound A has stopped. In this example, the time when the electronic sound A is sounding and the time when the electronic sound A has stopped are each approximately 0.5 seconds. Therefore, in this example, the time from when the electronic sound A stops sounding until the next electronic sound A starts sounding is approximately 1 second.

[0044] Here, the number of times the auditory notification unit 235 sounds the electronic sound A at 0.5 - second intervals is set to 10 times in this example from when the spinal measurement device 1 starts the measurement until it ends. As a result, the time for the spinal measurement device 1 to move from the buttocks S at the measurement start point to the neck E at the measurement end point is approximately 10 seconds. Note that this approximately 10 seconds includes a stop time of approximately 0.5 seconds after the electronic sound A that started sounding for the 10th time stops, as shown in Fig. 6.

[0045] Also, although there are individual differences, the length between the buttocks S and the neck E of the spinal column SV of the subject P is generally approximately 400 - 450 mm. Thus, a measurer such as a doctor or a technician moves the spinal measurement device 1 between the buttocks S and the neck E of the spinal column SV of the subject P within approximately 10 seconds. That is, the measurer moves the spinal measurement device 1 a distance of approximately 40 - 45 mm within approximately 1 second.

[0046] The auditory notification unit 235 is arranged in the left part within the main body unit 20. At the location corresponding to the auditory notification unit 235 in the main body unit 20, a plurality of small holes 203 are provided. The electronic sound A emitted from the auditory notification unit 235 is sounded outside the main body unit 20 through the small holes 203 from within the main body unit 20.

[0047] Note that as an alternative to the auditory notification unit 235 as the notification unit, a visual notification unit as the notification unit may be used. Or, both the auditory notification unit 235 and the visual notification unit may be used. As the visual notification unit, an LED lamp is used to perform notification by lighting and extinguishing the LED lamp.

[0048] (Explanation of the display units 232, 233L, 233R, 234, operation switches 236, 237, 238) The display units 232, 233L, 233R, 234 include a first display unit 232, a left second display unit 233L, a right second display unit 233R, and a differential second display unit 234. The display units 232, 233L, 233R, 234 are arranged as shown in FIGS. 1 and 2. Note that the arrangement of the display units 232, 233L, 233R, 234 is not limited to this example. Also, as the display unit, in addition to these display units 232, 233L, 233R, 234, a display unit for notifying the replacement of the dry battery which is the power supply unit 223, or a display unit for notifying the power supply of the rechargeable battery which is the power supply unit 223 may be provided.

[0049] The first display unit 232 displays the angle data D output by the control unit 230 in real time. The first display unit 232 is composed of a plurality of electronic display units, in this example, 11 LED lamps. The 11 LED lamps are linearly arranged side by side in the left - right direction, i.e., in the X - axis direction, on the front surface of the main body unit 20.

[0050] And when the angle data D is about 0°, the central LED lamp lights up.

[0051] On one hand, when the angle data D is the MAX angle data and is greater than about 0° and less than about 2°, the first LED lamp to the left of the central LED lamp lights up. Hereinafter, when the angle data D is the MAX angle data and is greater than or equal to about 2° and less than about 4°, the second LED lamp to the left of the central LED lamp lights up. When the angle data D is the MAX angle data and is greater than or equal to about 4° and less than about 6°, the third LED lamp to the left of the central LED lamp lights up. When the angle data D is the MAX angle data and is greater than or equal to about 6° and less than about 8°, the fourth LED lamp to the left of the central LED lamp lights up. When the angle data D is the MAX angle data and is greater than or equal to about 8°, the fifth LED lamp to the left of the central LED lamp lights up.

[0052] Also, when the angle data D is the min angle data and is greater than about 0° and less than about 2°, the first LED lamp to the right of the central LED lamp lights up. Hereinafter, when the angle data D is the min angle data and is greater than or equal to about 2° and less than about 4°, the second LED lamp to the right of the central LED lamp lights up. When the angle data D is the min angle data and is greater than or equal to about 4° and less than about 6°, the third LED lamp to the right of the central LED lamp lights up. When the angle data D is the min angle data and is greater than or equal to about 6° and less than about 8°, the fourth LED lamp to the right of the central LED lamp lights up. When the angle data D is the min angle data and is greater than or equal to about 8°, the fifth LED lamp to the right of the central LED lamp lights up.

[0053] Note that on the front surface of the main body 20, above the 11 LED lamps of the first display unit 232, the numbers "10", "8", "6", "4", "2", "0", "2", "4", "6", "8", "10" are written in order from left to right. These numbers indicate the angles, that is, the angle at which the spinal column SV at the measurement point M is not rotated or inclined, or the angle at which it is rotated or inclined to the left, or the angle at which it is rotated or inclined to the right.

[0054] The left second display unit 233L displays the MAX angle data numerically. That is, the control unit 230 converts the physical quantity angle, which is the MAX angle data, into a numerical value, and that numerical value is displayed on the left second display unit 233L. In this example, the left second display unit 233L is an LCD, i.e., a liquid crystal display, and is provided on the left side of the upper side of the first display unit 232 on the front surface of the main body unit 20. That is, the left second display unit 233L is provided at a location corresponding to the left side of the subject P.

[0055] The right second display unit 233R displays the min angle data numerically. That is, the control unit 230 converts the physical quantity angle, which is the min angle data, into a numerical value, and that numerical value is displayed on the right second display unit 233R. In this example, the right second display unit 233R is an LCD, i.e., a liquid crystal display, and is provided on the right side of the upper side of the first display unit 232 on the front surface of the main body unit 20. That is, the right second display unit 233R is provided at a location corresponding to the right side of the subject P.

[0056] The difference second display unit 234 displays the difference value between the numerical value of the MAX angle data and the numerical value of the min angle data. In this example, the difference second display unit 234 is an LCD, i.e., a liquid crystal display, and is provided above the first display unit 232 on the front surface of the main body unit 20, between the left second display unit 233L and the right second display unit 233R.

[0057] The numerical values displayed on the left second display unit 233L, the right second display unit 233R, and the difference second display unit 234 indicate the angle at which the spinal column SV at the measurement point M is not rotated or inclined, or the angle at which it is rotated or inclined to the left, or the angle at which it is rotated or inclined to the right.

[0058] (Description of the operation switches 236, 237, 238) The operation switches 236, 237, and 238 include a first operation switch 236, a second operation switch 237, and a third operation switch 238. Note that the arrangement of the operation switches 236, 237, and 238 is not limited to this example. Also, operation switches other than the operation switches 236, 237, and 238 may be provided.

[0059] The first operation switch 236 is a switch for starting and stopping the measurement of the spinal measurement device 1, and is provided at the center below the first display unit 232 on the front surface of the main body unit 20.

[0060] The second operation switch 237 is a power on / off switch for turning on and off the power of the spinal measurement device 1, and is provided on the left side of the first operation switch 236.

[0061] The third operation switch 238 is a calibration switch or a clear switch for performing 0 correction of the angle, and is provided on the right side of the first operation switch 236.

[0062] (Description of the roller member 3) As shown in FIGS. 1 to 4, the roller member 3 is rotatably attached to the main body member 2 around the rotation axis V, and contacts a predetermined part of the subject P directly or through clothing to guide the movement of the main body member 2 along the spinal column SV. The roller member 3 includes a rotating part 30, an anti-slip part 31, a mounting part 32, a second moving distance measuring part 33, and a mark 34 as a guideline.

[0063] (Description of the rotating part 30, the anti-slip part 31, and the mounting part 32) The rotating part 30 contacts a predetermined part of the subject P directly or through clothing and rotates. The rotating part 30 has a hollow or solid cylindrical shape. The diameter of the central part of the rotating part 30 in the direction of the rotation axis V is smaller than the diameters of the left and right end parts of the rotating part 30 in the direction of the rotation axis V. Also, the diameter of the rotating part 30 gradually changes from both ends to the center and is minimum at the center. The member of the rotating part 30 is not particularly limited.

[0064] The anti-slip portion 31 is provided on the circumferential surface of the rotating portion 30 that comes into contact with a predetermined part of the subject P. In this example, it is provided on the circumferential surfaces of the left and right end portions. The anti-slip portion 31 is, for example, a sheet-like one having small irregularities or a sheet-like one having raised hairs, and when the rotating portion 30 rotates while contacting a predetermined part of the subject P, it suffices if it has an anti-slip function to prevent the rotating portion 30 from slipping and idling. Note that the anti-slip portion 31 does not need to be provided on the entire circumferential surface of the rotating portion 30, and it may be provided in an area having an anti-slip function.

[0065] The attachment portion 32 is composed of a rigid round bar member. The left and right end portions of the attachment portion 32 are bent in the X-axis direction and in the direction of the rotation axis V, and are rotatably attached to the central portions of the left and right end faces of the rotating portion 30. The central portion of the attachment portion 32 is parallel to the X-axis direction and the direction of the rotation axis V, penetrates through the upper portion of the main body portion 20, and is fixed to the main body portion 20. Thereby, the measurement point M and the angle sensor 4 are relatively fixed.

[0066] (Explanation of the second moving distance measurement unit 33) The second moving distance measurement unit 33 is provided at a location on the circumferential surface of the rotating portion 30 that faces the first moving distance measurement unit 221 through the opening 200 of the main body portion 20. In this example, the second moving distance measurement unit 33 is a plurality of reflecting surfaces or a plurality of magnets, and is provided at equal intervals on the circumferential surface of the rotating portion 30. The second moving distance measurement unit 33 intermittently reflects light from the plurality of reflecting surfaces or intermittently emits magnetism from the plurality of magnets. The light intermittently reflected from the plurality of reflecting surfaces or the magnetism intermittently emitted from the plurality of magnets enters the optical sensor or magnetic sensor of the first moving distance measurement unit 221 through the opening 200 of the main body portion 20. Thereby, the rotation speed of the roller member 3 is detected non-contact, and in the control unit 230, the moving distance is calculated from the diameter of the rotating portion 30 of the roller member 3, and the distance that the main body member 2 moves along the spinal column SV from the buttocks S of the subject P, which is the measurement start point, to the neck E of the subject P, which is the measurement end point, is obtained.

[0067] (Description of the Mark 34) The mark 34 as a guideline is attached to the minimum diameter portion of the central part of the circumferential surface of the rotating part 30 of the rotating part 30. The line direction of this mark 34 coincides with the Y-axis direction. By aligning the line direction of this mark 34 with the spinal column SV of the subject P, the roller member 3 can be rotated linearly with respect to the spinal column SV, and the main body member 2, that is, the spinal column measuring device 1, can be linearly moved between the buttocks S and the neck E of the subject P, and the linearity when the angle sensor 4 acquires the angle of the spinal column SV can be supported.

[0068] (Handling of the Spinal Column Measuring Device 1 When Measuring the Spinal Column) First, the handling of the spinal column measuring device 1 by a measurer such as a doctor or a technician when measuring the spinal column will be described. The measurer operates the second operation switch 237 to turn on the power of the spinal column measuring device 1. Next, the measurer turns on the third operation switch 238 and holds the handle part 21, places the rotating part 30 of the roller member 3 on the buttocks S which is the measurement start point of the spinal column SV of the subject P, and performs 0 correction of the angle. When the preparation is complete in this way, the measurer turns on the first operation switch 236 and moves while contacting the spinal column SV to measure the state of the spinal column. Specifically, the measurer moves the main body member 2 from the buttocks S which is the measurement start point of the spinal column SV of the subject P to the neck E which is the measurement end point at a speed of about 40 to 45 mm per second while rotating the rotating part 30 of the roller member 3. After that, the measurer turns off the first operation switch 236.

[0069] (Description of the Spinal Column Measurement Process) With reference to the flowchart of FIG. 5, the spinal column measurement process of the spinal column measuring device 1 will be described. First, the sampling process shown in A of FIG. 5 will be described.

[0070] When the first operation switch 236 is turned on by the measurer, in step S101, the control unit 230 samples the angular information around the three axes X, Y, and Z at the measurement point M detected by the angle sensor 4. Specifically, the control unit 230 acquires the angular information around the three axes X, Y, and Z at the measurement point M detected by the angle sensor 4 at predetermined time intervals.

[0071] In step S102, the control unit 230 converts the sampled angular information into the angular data D around the Y axis at the measurement point M through high-speed and high-precision processing of the Madwick filter. Note that the angular data D around the Y axis at the measurement point M is appropriately referred to as the Y-axis data YD.

[0072] In step S103, the control unit 230 calculates the moving average value of the Y-axis data YD. In the case of this example, the moving average value is calculated for 20 consecutive Y-axis data.

[0073] In step S104, the control unit 230 sequentially stores (BUFF stores) the moving average value of the Y-axis data YD (hereinafter referred to as the Y-axis data YDA) in the storage unit 231.

[0074] Thereafter, in step S105, the control unit 230 waits for 0.01 seconds, returns to step S101, and repeats the subsequent processing until, for example, the first operation switch 236 is turned off.

[0075] (Explanation of measurement process) The measurement process shown in B of FIG. 5 will be described. When the first operation switch 236 is turned on by the measurer, the process starts. In step S201, the control unit 230 acquires one Y-axis data YDA (the moving average value of the Y-axis data YD) stored in the storage unit 231 in the order stored in the storage unit 231 from step S104, and proceeds to steps S202 and S207, respectively.

[0076] In step S202, the control unit 230 determines whether the Y-axis data YDA acquired in step S201 is greater than the maximum Y-axis data YDU stored in a maximum value storage unit (not shown) in the storage unit 231. If in step S202 it is determined that the Y-axis data YDA is greater than the maximum Y-axis data YDU, then in step S203, the control unit 230 stores the Y-axis data YDA in the maximum value storage unit instead of the maximum Y-axis data YDU stored in the maximum value storage unit.

[0077] If in step S202 it is determined that the Y-axis data YDA is not greater than the maximum Y-axis data YDU, or after the process of step S203, in step S204, the control unit 230 determines whether the Y-axis data YDA acquired in step S201 is less than the minimum Y-axis data YDD stored in a minimum value storage unit (not shown) in the storage unit 231. If in step S204 it is determined that the Y-axis data YDA is less than the minimum Y-axis data YDD, then in step S205, the control unit 230 stores the Y-axis data YDA in the minimum value storage unit instead of the minimum Y-axis data YDD stored in the minimum value storage unit (not shown) in the storage unit 231.

[0078] If in step S204 it is determined that the Y-axis data YDA is not less than the minimum Y-axis data YDD, or after the process of step S205, in step S206, the control unit 230 integerizes the maximum Y-axis data YDU stored in the maximum value storage unit and the minimum Y-axis data YDD stored in the minimum value storage unit, respectively.

[0079] Steps from step S201 to step S207 will be described. In step S207, the control unit 230 converts the Y-axis data YDA acquired in step S201 into display data for the first display unit 232 and proceeds to the next step S208.

[0080] In step S208, the control unit 230 causes the 11 LED lamps provided corresponding to the back sides of the numbers "10", "8", "6", "4", "2", "0", "2", "4", "6", "8", "10" on the first display unit 232 to turn on or off based on the display data.

[0081] After the process of step S206 or step S208 is performed, in step S209, the control unit 230 waits for 0.1 seconds and proceeds to the next step S210.

[0082] In step S210, the control unit 230 determines whether the first operation switch 236 is off. Here, if the first operation switch 236 is on, it returns from step S210 to step S201, and if the first operation switch 236 is off, it proceeds from step S210 to step S211.

[0083] In step S211, the control unit 230 displays the maximum Y-axis data YDU stored in the maximum value storage unit, the minimum Y-axis data YDD stored in the minimum value storage unit, and the value obtained by subtracting the minimum Y-axis data YDD from the maximum Y-axis data YDU.

[0084] That is, the left second display unit 233L displays the numerical value of the maximum Y-axis data YDU integerized in step S206 as the angle at which the spine SV of the subject P rotates or tilts to the left. Also, the right second display unit 233R displays the numerical value of the minimum Y-axis data YDD integerized in step S206 as the angle at which the spine SV of the subject P rotates or tilts to the right. Further, the difference second display unit 234 displays the numerical value of the difference between the numerical value displayed on the left second display unit 233L and the numerical value displayed on the right second display unit 233R. Then, the measurement process ends.

[0085] Here, when the spinal measurement device 1 moves along the spine SV of the subject P from the buttocks S to the neck E to measure the rotation or inclination of the spine SV of the subject P, the first movement distance measurement unit 221 of the main body member 2 and the second movement distance measurement unit 33 of the roller member 3 measure the distance from the buttocks S of the spinal measurement device 1. At the same time, the angle sensor built into the angle sensor 4 also measures the distance from the buttocks S of the spinal measurement device 1 in the same way.

[0086] (Explanation of the effect of the spinal measurement device 1) The spinal measurement device 1 according to this embodiment is composed of the above configuration and operation, and the effects will be described below.

[0087] The spinal measurement device 1 according to this embodiment includes a main body member 2, a roller member 3, an angle sensor 4, a control unit 230, and display units 232, 233L, 233R, 234, and the angle sensor 4 is arranged at the center of gravity point G of the spinal measurement device 1. As a result, in the spinal measurement device 1 according to this embodiment, even if the main body member 2 where the angle sensor 4 is arranged is bent or distorted, or even if the roller member 3 rotatably attached to the main body member 2 is bent or distorted, and furthermore, even if the weight balance of the spinal measurement device 1 in the front, rear, left, and right directions is uneven, the error when the angle sensor 4 detects angle information at the measurement point M can be suppressed. Thereby, the spinal measurement device 1 according to this embodiment can measure the angle of the spine SV of the subject P with high precision compared to the spinal measurement device of Patent Document 1 in which the three-axis angle sensor of the spatial coordinate collection device is simply provided on the measurement main body.

[0088] Moreover, since the angle sensor 4 is arranged at the center of gravity point G of the spinal measurement device 1 in the spinal measurement device 1 according to this embodiment, it is only necessary to perform 0 correction of the angle before starting the measurement. That is, in the spinal measurement device 1 according to this embodiment, even if the main body member 2 is bent or distorted and the roller member 3 is bent or distorted, the center of gravity point G of the spinal measurement device 1 where the angle sensor 4 is arranged will not be bent or distorted, so there is no need to perform 0 correction of the angle.

[0089] In the spinal measurement device 1 according to this embodiment, the angle sensor 4 uses the origin of the spatial coordinates as the measurement point M, and the angle sensor 4 and the measurement point M are relatively fixed. As a result, the spinal measurement device 1 according to this embodiment can keep the relative distance between the angle sensor 4 and the measurement point M constant, so that the angle sensor 4 can detect angle information with high accuracy at the measurement point M. Thereby, the angle of the spinal column SV of the subject P can be measured with high accuracy.

[0090] In the spinal measurement device 1 according to this embodiment, when the main body member 2, that is, the spinal measurement device 1 moves along the spinal column SV from the measurement start point to the measurement end point of the spinal column SV, an auditory notification unit 235 as a notification unit that notifies every predetermined time, in this example, every 0.5 seconds, is provided. As a result, in the spinal measurement device 1 according to this embodiment, the measurer can move the main body member 2, that is, the spinal measurement device 1, at a constant speed from the measurement start point to the measurement end point of the spinal column SV in accordance with the sound notified from the auditory notification unit 235. Thereby, the spinal measurement device 1 according to this embodiment can evenly measure the distance from the measurement start point to the measurement end point of the spinal column SV, and moreover, can prevent the roller member 3 from leaving the spinal column SV of the subject P by moving the main body member 2, that is, the spinal measurement device 1 quickly. Therefore, the angle of the spinal column SV of the subject P can be measured with high accuracy without measurement errors.

[0091] In the spinal measurement device 1 according to this embodiment, the main body member 2 and the roller member 3 are provided with movement distance measuring devices 221, 33 for measuring the movement distance of the main body member 2. As a result, the spinal measurement device 1 according to this embodiment can measure the movement distance of the main body member 2 by the movement distance measuring devices 221, 33, so that the average of the movement distance of the main body member 2 obtained from the acceleration sensor built in the angle sensor 4 can be calculated. Thereby, the spinal measurement device 1 according to this embodiment can reduce the error of the movement distance of the main body member 2, so that the angle of the spinal column SV of the subject P can be measured with high accuracy.

[0092] In the spinal measurement device 1 according to this embodiment, the roller member 3 is provided with a rotating portion 30. Since this rotating portion 30 rotates in contact with the subject P directly or through clothing, the unevenness of the spinal column SV of the subject P, that is, the protrusions and depressions, can be surely grasped. Therefore, the angle of the spinal column SV of the subject P can be measured with high precision without measurement errors. Further, in the spinal measurement device 1 according to this embodiment, due to the rotating portion 30 of the roller member 3, it is not necessary for the subject P to expose the upper body, and measurement can be performed even from above clothing such as a thin T-shirt.

[0093] In the spinal measurement device 1 according to this embodiment, since the anti-slip portion 31 is provided on at least a part of the circumferential surface of the rotating portion 30 of the roller member 3 that comes into contact with the subject P, the anti-slip portion 31 can come into contact with the subject P directly or through clothing. As a result, the spinal measurement device 1 according to this embodiment can surely rotate while contacting the spinal column SV of the subject P by the rotating portion 30 of the roller member 3. Thereby, the angle of the spinal column SV of the subject P can be measured with high precision without measurement errors. Moreover, in the spinal measurement device 1 according to this embodiment, since the rotating portion 30 of the roller member 3 rotates surely, the rotation of the clothing by the rotating portion 30 does not occur.

[0094] In the spinal measurement device 1 according to this embodiment, among the circumferential surface of the rotating portion 30, a mark 34 as a guideline is attached on the circumference centered on the rotation axis V at the central portion in the direction of the rotation axis V. Therefore, the line direction of the mark 34 and the Y-axis direction coincide. As a result, in the spinal measurement device 1 according to this embodiment, by aligning the line direction of the mark 34 with the spinal column SV of the subject P, the roller member 3 can be rotated linearly with respect to the spinal column SV, and the main body member 2, that is, the spinal measurement device 1 can be linearly moved between the buttocks S and the neck E of the subject P. The linearity when the angle sensor 4 acquires the angle of the spinal column SV can be supported, and measurement errors can be prevented.

[0095] The spinal measurement device 1 according to this embodiment has a control unit 230, and this control unit 230 outputs the angle information output from the angle sensor 4 as angle data D. The angle data D includes 0° angle data D when the spinal column SV is not rotating or tilting, positive angle data D when the spinal column SV is rotating or tilting to the left side of the subject P, and negative angle data D when the spinal column SV is rotating or tilting to the right side of the subject P. As a result, the spinal measurement device 1 according to this embodiment can accurately measure the angle of the spinal column SV of the subject P based on the angle data D output by the control unit 230.

[0096] The spinal measurement device 1 according to this embodiment includes, as a display unit, a first display unit 232 that displays the angle data D in real time, a left second display unit 233L that displays the positive angle data D numerically, a right second display unit 233R that displays the negative angle data D numerically, and a difference second display unit 234 that displays the difference value between the numerical value of the positive angle data D and the numerical value of the negative angle data D. As a result, with the first display unit 232, the left second display unit 233L, the right second display unit 233R, and the difference second display unit 234, the measurer can perform the measurement while viewing the display units 232, 233L, 233R, 234, so that the angle of the spinal column SV of the subject P can be accurately measured.

[0097] The spinal measurement device 1 according to this embodiment is configured such that the first display unit 232 is composed of a plurality of electronic display units arranged side by side in the left-right direction of the subject P with respect to the moving direction of the main body member 2. The left second display unit 233L is provided at a location on the main body member 2 corresponding to the left side of the subject P with respect to the moving direction. The right second display unit 233R is provided at a location on the main body member 2 corresponding to the right side of the subject P with respect to the moving direction. The differential second display unit 234 is provided between the left second display unit 233L and the right second display unit 233R. As a result, when the spinal measurement device 1 according to this embodiment measures by moving the main body member 2 between the buttocks S and the neck E of the spinal column SV of the subject P, the arrangement of the display units 232, 233L, 233R, 234 provided on the main body member 2 matches the left and right of the subject P. Therefore, the measurer can accurately grasp the angle data D displayed on the display units 232, 233L, 233R, 234 and the left and right of the subject P, and can measure the angle of the spinal column SV of the subject P with high accuracy.

[0098] [Appendix] The content described in several of the above-described embodiments is understood as follows, for example.

When the main body member 2 moves along the spinal column SV from the measurement start point to the measurement end point of the spinal column SV, it detects the angle information of the spinal column SV and outputs it to the control unit 230, The control unit 230 is housed in the main body member 2, converts the angle information output from the angle sensor 4 into angle data D, The display units 232, 233L, 233R, and 234 are provided on the main body member 2 and display the angle data D converted by the control unit 230.

[0101] Moreover, since the angle sensor 4 is arranged at the center of gravity point G of the spinal measurement device 1 in the spinal measurement device 1 according to this embodiment, it is only necessary to perform zero correction of the angle before starting the measurement. That is, in the spinal measurement device 1 according to this embodiment, even if the main body member 2 is bent or distorted and the roller member 3 is bent or distorted, the center of gravity point G of the spinal measurement device 1 where the angle sensor 4 is arranged is not bent or distorted, so there is no need to perform zero correction of the angle.

[0102] (2) The angle sensor 4 uses the measurement point M as the origin of the space coordinates, The X-axis of the space coordinates is the rotation axis V, The Y-axis of the space coordinates is the axis in the direction of the spine SV and is the axis in the direction in which the main body member 2 moves along the spine SV. The Z-axis of the space coordinates is the axis in the direction orthogonal to the spine SV. The angle sensor 4 and the measurement point M are relatively fixed. This is a feature.

[0103] As a result, the spinal measurement device 1 according to this embodiment can keep the relative distance between the angle sensor 4 and the measurement point M constant. Therefore, the angle sensor 4 can detect angle information with high precision at the measurement point M, and thereby, the angle of the spinal column SV of the subject P can be measured with high precision.

[0104] (3) The main body member 2 is provided with a notification unit 235 that notifies at predetermined time intervals when the main body member 2 moves along the spinal column SV from the measurement start point to the measurement end point of the spinal column SV. This is a feature.

[0105] As a result, the spinal measurement device 1 according to this embodiment enables the measurer to move the main body member 2, that is, the spinal measurement device 1, at a constant speed from the measurement start point to the measurement end point of the spinal column SV in accordance with the sound notified from the auditory notification unit 235. Thereby, the spinal measurement device 1 according to this embodiment can measure evenly from the measurement start point to the measurement end point of the spinal column SV, and moreover, can prevent the roller member 3 from separating from the spinal column SV of the subject P by moving the main body member 2, that is, the spinal measurement device 1, quickly. Therefore, the angle of the spinal column SV of the subject P can be measured with high precision without measurement errors.

[0106] (4) The main body member 2 and the roller member 3 are provided with a moving distance measuring device 221, 33 for measuring the moving distance of the main body member 2. This is a feature.

[0107] As a result, the spinal measurement device 1 according to this embodiment can measure the moving distance of the main body member 2 by the moving distance measuring devices 221 and 33, and thus can calculate the average of the moving distance of the main body member 2 obtained from the acceleration sensor built in the angle sensor 4. Thereby, the spinal measurement device 1 according to this embodiment can reduce the error of the moving distance of the main body member 2, and thus can measure the angle of the spinal column SV of the subject P with high accuracy.

Further, in the spinal measurement device 1 according to this embodiment, due to the rotating part 30 of the roller member 3, it is not necessary for the subject P to expose the upper body, and the measurement can be performed even from above clothing such as a thin T-shirt.

As a result, the spinal measurement device 1 according to this embodiment can surely rotate while contacting the spinal column SV of the subject P at the rotating portion 30 of the roller member 3, and thereby, the angle of the spinal column SV of the subject P can be measured with high precision without measurement error. Moreover, since the rotating portion 30 of the roller member 3 surely rotates in the spinal measurement device 1 according to this embodiment, the rotation of the clothing by the rotating portion 30 does not occur.

[0111] (6) Among the circumferential surface of the rotating portion 30, a mark 34 as a guideline is attached on the circumference centered on the rotation axis V at the central portion in the direction of the rotation axis V. It is characterized by this.
