Description

Technical Field

[0001] The invention relates to a spine measuring instrument. Background Art

[0002] A spinal measuring instrument is an advanced medical device used to measure and assess spinal health. Leveraging modern sensor technology, image processing techniques, and biomechanical principles, it can accurately capture and analyze three-dimensional spinal morphological data, providing doctors with important information about spinal health. Patent application number 202220080449.3, entitled "A Multifunctional Electronic Scoliosis Measuring Instrument," comprises a first base, with a column welded to the right side of the top of the first base, symmetrically distributed second bases welded to the left side of the top of the first base, and sliding frames welded to the tops of both second bases. A symmetrically distributed porous frame is welded to the top of the first base in the direction in which the two second bases approach each other. Positioning pins are inserted into the porous frame, and a movable tripod is welded to the top of each positioning pin. In this utility model, the multifunctional electronic scoliosis measuring instrument avoids side-to-side body swaying during measurement, reduces lateral errors caused by side-to-side body movement, and improves measurement accuracy. By rotating the frame downward, the front of the screen can be aligned with the left side of the placement box, making the screen dustproof and helping to increase the service life of the device.

[0003] Most existing spinal measurement devices on the market can only perform tests in a single position, including standing and flexion measurements. Depending on the patient's age and medical history, some are not suitable for standing and flexion measurements, forcing some patients to seek out hospital X-rays, which is costly. Three-dimensional electronic spinal measuring devices primarily measure scoliosis in a standing position; flexion tests are typically performed with a traditional measuring tape. Prone tests rely primarily on manual observation. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide a spinal measuring instrument that can collect and analyze information on spinal conditions in standing, flexed, and prone positions. It can adapt to more different types of patients and improve measurement accuracy by collecting and comprehensively judging spinal information in multiple postures.

[0005] To achieve the above-mentioned purpose, the present invention proposes a spine measuring instrument, including a suction cup base, a vertical pole connected to the suction cup base, a first sensor extending laterally from the top front end of the vertical pole, the first sensor being used to collect data of the patient's back in a forward bending state, a second sensor being vertically provided on the rear end face of the vertical pole, the second sensor being used to collect data of the patient's back in a standing state, a bending prompting piece being provided at the top front end of the vertical pole, the bending prompting piece including a plurality of distance measuring sensors, the plurality of distance measuring sensors being used to measure the vertical distance from the buttocks, the vertical distance from the neck, and the horizontal distance from the neck to the buttocks, respectively, and comparing the values ​​with the patient's bending standard threshold value, when it is less than the minimum standard value, the patient is prompted to bend further until the standard is reached, and when the standard value is reached or within the standard threshold value, the patient is prompted to continue to maintain the action.

[0006] Furthermore, the suction cup base is hinged to the vertical pole and a locking portion is provided at the hinge. Extension portions are provided on both the left and right sides of the vertical pole. The extension portions and the front end faces of the vertical pole are both provided with data acquisition components. When the vertical pole is in a horizontal locking state, the extension portions and the vertical pole together form a lying area for the patient to lie prone. The data acquisition component is used for collecting data on the back of the patient in the prone state.

[0007] Furthermore, the suction cup base is provided with a hinge seat, the hinge seat is provided with a cavity for the hinge head at the bottom of the vertical pole to be hinged, the cavity is provided with a vertical abutment surface and a horizontal abutment surface, a driving member is provided on the side of the hinge seat, the driving member is used to drive the hinge head of the vertical pole to rotate in the cavity, a slot is provided at the vertical bottom of the vertical pole, a vertically movable plug is provided at the vertical abutment surface corresponding to the slot, and a magnetic suction part is provided between the horizontal abutment surface and the end face of the vertical pole in contact.

[0008] Furthermore, the expanded extension portion includes cavities symmetrically provided on the left and right sides of the vertical pole, an extension plate is slidingly connected in the cavity, the extension plate is slidingly connected to the cavity, and the end faces of the extension plates close to the top of the vertical pole are provided with support seats, and a telescopic connecting rod is provided between the support seats.

[0009] Furthermore, the extension plate is provided with a filling portion, which is used to be in the same horizontal plane as the vertical pole. The filling portion includes a groove on the upper end surface of the extension plate, a filling plate is vertically slidably connected in the groove, and a lifting member is provided between the bottom of the filling plate and the bottom of the groove.

[0010] Furthermore, partitioned airbags are distributed on the front end surfaces of the filling plate and the uprights, and the partitioned airbags include head area airbags, cervical spine area airbags, thoracic spine and lumbar spine area airbags and limb area airbags. A data acquisition component is provided in the partitioned airbags, and the data acquisition component includes multiple pressure sensors, which collect pressure data of various areas of the spine when lying prone through the pressure sensors.

[0011] Furthermore, the airbag in the head area is set as a small oval airbag, which is filled with sponge and has a pressure sensor at the center of the bottom of the airbag; the airbag in the cervical spine area is set as an arc-shaped airbag that conforms to the physiological curvature of the cervical spine, and the pressure airbags are evenly distributed on the inner surface of the airbag and arranged along the curve of the cervical spine; the airbag in the thoracic and lumbar spine area is set as a harder large airbag, and the pressure sensors are distributed in a matrix; the airbag in the limb area is set as a long strip airbag, and the pressure sensor is installed in the middle of the airbag.

[0012] Furthermore, a plurality of storage cavities are provided at the bottom of the extension plate, elastic baffles are provided at the openings of the storage cavities, and support rods are hinged in the storage cavities.

[0013] Furthermore, it also includes a converter, which converts the sensing signal into a digital signal. The data processing module determines the patient's spinal status through the digital signal and feeds back on the display screen of the control panel.

[0014] Beneficial effects:

[0015] 1. The present application is provided with a bending reminder. In the prior art, the bending measurement action is not standard, which leads to incomplete or inaccurate back data collection. The bending reminder includes multiple distance measuring sensors. The distance is measured by the distance measuring sensor and then combined with the calculation formula to obtain the current bending angle of the patient. The patient is then compared and proofread to prompt to continue bending or to maintain the action, ensuring the standardization of the forward bending action. The bending standard can also be comprehensively judged based on the patient's personal information and physical condition to avoid excessive bending injury.

[0016] 2. The present application also provides a lying area capable of performing prone measurements. The lying area includes a vertical pole and extended portions on the left and right sides of the vertical pole. The area of ​​the lying area is increased by lateral extension of the extended portions to adapt to the patient's body size. The extended portions and the vertical poles are provided with partitioned airbags and data acquisition components. The airbags will deform to varying degrees due to pressure on various parts of the human body. A pressure sensor is installed in the airbag, which converts the pressure signal into an electrical signal and transmits it to the processing module of the measuring instrument. Based on the pressure data of the airbags in different areas, the force distribution of each segment of the spine is analyzed to determine whether the spine has abnormal conditions such as scoliosis, lordosis or kyphosis.

[0017] 3. The zoned airbags in this application can achieve personalized fit and support by adjusting the inflation volume of the airbags in each area according to the patient's body shape and spinal condition, thereby improving measurement accuracy and patient comfort.

[0027] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0028] Refer to Figure 1-Figure 2As shown, the present application provides a first embodiment of a spinal measurement instrument, comprising a suction cup base 1, to which a vertical pole 2 is connected. A first sensor 3 extends laterally from the top front end of the vertical pole 2. The first sensor is used to collect data about the patient's back while flexed. A second sensor 4 is vertically mounted on the rear end of the vertical pole 2. The second sensor 4 is used to collect data about the patient's back while standing. The instrument also includes a converter for converting sensor signals into digital signals and a data processing module. The data processing module uses the digital signals to determine the patient's spinal condition and provides feedback on the display screen 141 of the control panel 14. A bending reminder 5 is provided at the top front end of the vertical pole 2. The bending reminder 5 is set to three standards based on the patient's age and medical history. Assuming the patient is able to bend, the standard bending angle for adolescents is 50°-70°, for adults it is 40°-60°, and for the elderly it is 30°-50°. Therefore, the bending reminder 5 is provided to remind patients to reach the corresponding bending angle standard, thereby obtaining more accurate back information and better measurement data. First, when the patient performs the measurement, he or she puts his or her hands together, bends forward, and rotates forward around the waist. As shown in the figure, the buttocks are used as fixed anchor points and the neck is used as a movable anchor point. Different bending angles of the human body can be measured using two fixed anchor points and one movable anchor point. Therefore, the bending prompting device 5 includes multiple distance measuring sensors 51, which need to measure three data: the distance from the vertical sensor to the buttocks, the distance from the vertical sensor to the neck, and the horizontal distance from the neck to the buttocks. The three distance data are transmitted to the control panel 14. The internal processor of the control panel 14 calculates and processes the patient's current bending angle through trigonometric functions and the Pythagorean theorem to determine whether the angle is within the corresponding standard. If the angle is below the lowest standard threshold, the prompt will prompt how many degrees more bending is required. If the physical condition does not allow excessive bending, the examiner can skip the bending prompting device 5 through the control panel 14 and directly collect back information or collect corresponding spinal information while standing. The distance measuring sensor 51 includes a fixed first distance measuring sensor 51, which is used to measure the vertical distance to the hips. Then, the second distance measuring sensor 51 is moved to the top of the patient's neck through camera tracking (this belongs to the existing technology and will not be described in detail here). The vertical distance to the neck is measured by the second distance measuring sensor 51. Then, a third distance measuring sensor 51 is also provided on the first distance measuring sensor 51 to measure the distance between the first distance measuring sensor 51 and the second distance measuring sensor 51, which is the horizontal distance from the hips to the neck. Specifically, if Figure 2As shown, the distance to the hip is set as X, the distance to the neck is set as Y, and the horizontal distance from the hip to the neck is set as Z. XY is the adjacent side distance, and Z is the opposite side distance. The hypotenuse distance is calculated using the Pythagorean theorem, and then the complementary angle of the required bending angle is calculated using trigonometric functions. The bending angle is then subtracted from the complementary angle from 180° to obtain the bending angle. The obtained bending angle is used to determine whether the forward flexion measurement is standard. Assuming that the patient is a teenager and has no conditions that prevent bending, the bending standard is 50°-70°. If the measured bending angle is less than 50°, the prompter will prompt the patient to continue bending according to the difference in degrees from 50°. If it is greater than 50°, the patient is prompted to maintain the movement and subsequent back information collection is performed.

[0029] Refer to Figure 3-Figure 8 As shown, the present application also provides a second embodiment, which is basically the same as the first embodiment, with the only difference being that: the measurement of the prone position is added. For patients who are unable to do forward bending movements, the spinal status can be obtained through prone measurement. Specifically, the suction cup base 1 is hinged to the vertical pole 2 and a locking portion is provided at the hinge. The vertical pole 2 is provided with an expansion extension portion 6 on both the left and right sides. The expansion extension portion 6 and the front end surface of the vertical pole 2 are both configured with a data acquisition component 7. When the vertical pole 2 is in a horizontal locking state, the expansion extension portion 6 and the vertical pole 2 together form a lying area 8 for the patient to lie prone. The data acquisition component 7 is used to collect data on the back spine of the patient in the prone state. The suction cup base 1 is provided with a hinge seat 9, and the hinge seat 9 is provided with a cavity 91 for placing the hinge head at the bottom of the upright pole 2. The cavity 91 is provided with a vertical abutment surface 92 and a horizontal abutment surface 93. A driving member 94 is provided on the side of the hinge seat 9. The driving member 94 is used to drive the rotation of the upright pole 2 in the cavity 91. The vertical bottom of the upright pole 2 will fit with the vertical abutment surface 92 and a vertically movable plug-in block 96 is provided on the vertical abutment surface 92. The plug-in block 96 will be pushed up by the horizontal push plate to connect the plug-in block 96 with the socket at the bottom of the upright pole 2, further enhancing the vertical stability. A magnetic part 97 is provided between the horizontal abutment surface 93 and the end face of the upright pole 2 to ensure the stability between the hinged ends when locked horizontally. A channel for line layout is provided inside the upright pole 2, and the line length has movable space to facilitate the deformation of the upright pole 2.

[0030] like Figure 5As shown, the extension portion 6 includes cavities 61 symmetrically disposed on the left and right sides of the upright 2. An extension plate 62 is disposed within the cavity 61 and is slidably connected to the cavity 61. A support seat 63 is disposed on the end surface of the extension plate 62 near the top of the upright 2. A telescopic connecting rod 64 is disposed between the support seats 63 to accommodate the extension of the extension plate 62. Because the extension plate 62 and the upright 2 are at different heights, uneven surfaces are generated. To fill these uneven surfaces and prevent them from affecting the accuracy of data collection, a filling portion is provided on the extension plate 62. The filling portion is used to align the extension plate 62 with the upright 2. The filling portion includes a groove disposed on the upper end surface of the extension portion. A filling plate 10 is vertically slidably connected to the groove. A lifting member 11 is disposed between the bottom of the filling plate 10 and the bottom of the groove. The lifting member 11 is driven by a filling airbag, a screw, or a gear to achieve vertical elevation of the filling plate 10 (this is prior art and will not be elaborated on here).

[0031] like Figure 5As shown, partitioned airbags 12 are distributed on the front end surfaces of the filling plate 10 and the upright 2. The partitioned airbags 12 are fixed or movable to the upright 2 and / or the filling plate 10. The filling plate 10 and the upright 2 are both provided with transverse and longitudinal slide rails, and the bottom of the slide rails are provided with multiple slots. The partitioned airbags 12 are provided with sliders corresponding to the slide slots, and the sliders are provided with clips corresponding to the slots. The position of the partitioned airbags 12 is fixed by the engagement of the clip keys with the slots. In this application, the partitioned airbags 12 are preferably fixed. The partitioned airbags 12 include airbags for the head area, airbags for the cervical spine area, airbags for the thoracic and lumbar spine areas, and airbags for the limbs. The data acquisition unit 7 is provided in the partitioned airbags 12, and the data acquisition unit 7 includes multiple pressure sensors 71. The head area airbag is a small oval-shaped airbag filled with sponge, with a pressure sensor 71 located at the center of its base. The cervical area airbag is an arc-shaped airbag that conforms to the physiological curvature of the cervical spine. Pressure airbags are evenly distributed on the inner surface of the airbag, arranged along the curve of the cervical spine. The thoracic and lumbar areas are equipped with larger, stiffer airbags, with pressure sensors 71 arranged in a matrix. The limb area airbags are long, strip-shaped airbags, with pressure sensors 71 installed in the middle. The airbag position is adjusted according to the patient's height to better fit the body and improve patient comfort. When a patient lies prone on the partitioned airbag 12, the airbag will deform to varying degrees due to pressure from different parts of the body. Pressure sensors 71 are installed inside the airbags, converting the pressure signals into electrical signals and transmitting them to the measuring instrument's processing module. Based on the pressure data from the airbags in different areas, the force distribution of each spinal segment is analyzed to determine whether there are abnormalities such as scoliosis, lordosis, or kyphosis in the spine. For example, if the airbag pressure in the left lumbar area is significantly higher than that on the right, it may indicate a tendency for the lumbar spine to curve to the right. The above configuration provides more comprehensive and detailed spinal pressure distribution data, addressing the shortcomings of traditional standing or flexion measurement methods. Furthermore, the zoned airbags 12 adjust the inflation volume of each zone according to the patient's body shape and spinal condition, achieving personalized fit and support, improving measurement accuracy and patient comfort. Airbag inflation can be achieved through external devices or equipped with intelligent control, which is a state-of-the-art technology and will not be elaborated on here.

[0032] In order to enhance the stable support of the expanded extension part 6, the extension plate 62 is provided with multiple storage cavities 13, and an elastic baffle is provided at the opening of the storage cavity 13. A support rod 131 is hinged in the storage cavity 13, and the support rod 131 is adjustable in length to support the middle part of the expanded extension part 6.

[0033] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
