Description

Technical Field

[0001] This invention relates to the field of testing instrument technology, and more specifically to a somatic sensation testing instrument. Background Technology

[0002] Currently, quantitative assessment of somatosensory function mainly relies on traditional methods, such as static posture recording, sensory tissue test (SOT), and single-modal sensory threshold detection such as vibration sense and position sense.

[0003] Existing somatic sensory testing devices typically only detect sensation in a single dimension, such as the front-back or left-right direction, and cannot simultaneously capture posture control sensitivity in two spatial dimensions. This results in incomplete clinical assessment information and affects diagnostic accuracy. At the same time, traditional contact sensors often use a single contact point or a flat pressure plate, which cannot distinguish the differences in sensory responses in different areas of the subject's front-back or left-right sides. This makes it difficult to accurately locate the specific locations of sensory desensitization or hypersensitivity, affecting the precision of lesion assessment.

[0004] Therefore, there is a need to provide a somatosensory testing device to solve the above problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a somatosensory testing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A somatosensory testing device includes a frame, the frame including a support plate, and a housing a and a housing b respectively at both ends of the support plate. A protective frame a is mounted on housing a, and a protective frame b is mounted on housing b.

[0008] As a further embodiment of the present invention, at least three abutting sliders are provided, and several abutting sliders are equidistantly distributed on the side of the connecting cylinder a that are close to each other.

[0009] As a further embodiment of the present invention, the horizontal adjustment assembly includes sliding seats respectively slidably disposed at both ends of the horizontal frame. An electric cylinder connected to the corresponding sliding seat is respectively provided on the side wall of the horizontal frame near the protective frame a. A connecting cylinder b is installed on the side of the sliding seat away from the protective frame a. The outer end of the connecting cylinder b is provided with a stepped annular groove corresponding to the end of the contacting slide bar. Both the connecting cylinder b and the connecting cylinder a are provided with corresponding slots. A sliding block symmetrically and movably connected to the slot is provided inside the connecting cylinder b. One end of the sliding block is provided with a sliding column. A T-shaped plate movably is provided at the end of the connecting cylinder b away from the connecting cylinder a. A symmetrical inclined groove is provided on the T-shaped plate to slide with the sliding column. One end of the T-shaped plate penetrates the bottom of the connecting cylinder b. A spring b is provided between the inner wall of the connecting cylinder b and the T-shaped plate.

[0010] As a further embodiment of the present invention, the left and right test components include connecting plates respectively disposed on the side of the cross frame and the support slide rod close to each other. The outer end of the connecting plate is provided with a frustum portion. Pressure sensors b are provided on the outer middle part of the frustum portion and on several inclined surfaces. The outer end of the connecting plate is connected to a hemispherical arc cover. The hemispherical arc cover has slots corresponding to several pressure sensors b one by one. A contact slide frame is slidably disposed in the slot. A spring c is connected between the pressure sensor b and the contact slide frame.

[0011] As a further embodiment of the present invention, the frustum portion is configured as a regular polyhedral frustum.

[0012] As a further embodiment of the present invention, an adjusting cylinder a is provided between the horizontal frame and the corresponding left and right test components.

[0013] As a further embodiment of the present invention, the first height adjustment component includes a screw a rotatably disposed inside the protective frame a, the screw a being threadedly connected to the lifting frame a, and one end of the screw a being connected to the motor a.

[0014] As a further embodiment of the present invention, the second height adjustment component includes a screw b rotatably disposed inside the protective frame b, the screw b being threadedly connected to the lifting frame b, one end of the screw b being connected to the motor b, and an adjustment module being provided between the lifting frame b and the support slide rod.

[0015] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art: 1. This invention, through anterior-posterior testing components positioned on the front and back sides of the subject and lateral-lateral testing components positioned on the left and right sides, can simultaneously capture somatosensory sensitivity in both the forward / backward (AP) and left / right (ML) spatial dimensions during active posture swaying. By using four preset levels of different swaying amplitudes (2cm-3.5cm in the forward / backward direction and 4cm-5.5cm in the lateral direction) and a randomized test sequence (40 times in total), the assessment task highly simulates real posture control scenarios, avoiding the diagnostic information loss caused by single-direction assessment. Simultaneously, the sensor accuracy reaches 0.001, providing highly reliable and valid multidimensional data support for clinical differentiation of peripheral neuropathy, vestibular dysfunction, and fall risk assessment in the elderly, significantly improving the comprehensiveness and reliability of diagnosis.

[0016] 2. The front and rear testing components of this invention employ multiple contact sliders distributed at equal angles around the circumference of the connecting cylinder, with each contact slider independently connected to a pressure sensor a; the left and right testing components employ a regular multifaceted truncated pyramid combined with a hemispherical arc cover, with pressure sensors b set on multiple inclined surfaces and in the middle, and pressure transmitted through contact sliders. This can divide the test areas on the front and rear sides and left and right sides of the subject into multiple independent detection zones. By monitoring the pressure changes in each zone in real time, the differences in sensory reaction speed and sensitivity in different local areas of the subject can be accurately determined. Compared with single-point detection, it can effectively locate the specific location of sensory abnormalities, providing a more refined quantitative basis for the localization diagnosis of nerve damage.

[0017] 3. In this invention, the connecting cylinder b in the horizontal adjustment assembly is movably connected to the connecting cylinder a of the front and rear test assemblies through a sliding block and a slot. With the cooperation of the T-plate, the inclined slot, and the spring b, the operator only needs to push the T-plate to disengage the block from the slot, thus enabling the connecting cylinder a to be quickly pulled out and separated. When inserted in the reverse direction, the inclined surface design guides the block to automatically reset and lock, completing the quick installation. This makes it convenient for the subject to climb onto or leave the support plate, avoiding the inconvenience of crossing a high platform or going around the equipment. At the same time, it facilitates the disassembly, storage, and protection of the front and rear test assemblies after the test, and also simplifies the inspection and replacement process of the pressure sensor a, improving the safety and maintenance efficiency of the equipment.

[0018] 4. This invention includes a first height adjustment component and a second height adjustment component. A motor-driven screw drives the lifting frame to slide, allowing independent adjustment of the vertical height of the front and rear testing components and the left and right testing components, ensuring they accurately correspond to the subject's anterior superior iliac spine and greater trochanter of the femur, respectively. Simultaneously, an electric cylinder in the horizontal adjustment component drives a sliding seat to move horizontally along the cross frame. Through cooperation with the limiting holes on the supporting slide rod, the horizontal position of the left and right testing components can be flexibly adjusted. This multi-degree-of-freedom adjustment method can accommodate subjects of different heights, body types, and standing postures, ensuring that each test is conducted under the same anatomical landmark reference, effectively improving the comparability and repeatability of test results between individuals.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0031] In one embodiment of the present invention, see Figures 1-2 A somatosensory testing device includes a frame 1, which includes a support plate 101. The support plate 101 has a housing a102 and a housing b104 at its two ends, respectively. A protective frame a103 is mounted on housing a102, and a protective frame b105 is mounted on housing b104. A control and display module 106, electrically connected to the electrical equipment on the testing device, is also provided on housing a102. A first height adjustment component 2 is provided inside the protective frame a103, and the first height adjustment component 2 includes a lifting frame slidably connected to the protective frame a103. a203, the outer end of the lifting frame a203 is connected to a horizontal frame 204, both ends of the horizontal frame 204 are provided with front and rear test components 3, the front and rear test components 3 are connected to the horizontal frame 204 through a horizontal adjustment component 4, the protective frame b105 is provided with a second height adjustment component 5, the second height adjustment component 5 includes a lifting frame b503 slidably connected to the protective frame b105, the outer end of the lifting frame b503 is slidably provided with a support slide rod 504, the horizontal frame 204 and the support slide rod 504 are both provided with left and right test components 6 at their respective close ends.

[0032] In this embodiment, in the initial state, the front and rear test components 3 and the horizontal adjustment components 4 are separated, and the horizontal frame 204 and the support slide 504 are both at their lowest points. When the subject stands at the corresponding position on the support plate 101, the subject is located between the two left and right test components 6 and corresponds to the middle of the horizontal frame 204. The horizontal adjustment components 4 located at both ends of the horizontal frame 204 are connected to the front and rear test components 3 to install the two front and rear test components 3 on the front and rear sides of the subject respectively.

[0033] Furthermore, the height of the horizontal adjustment component 4 and the anterior and posterior test components 3 can be adjusted by the first height adjustment component 2, so that the two anterior and posterior test components 3 correspond to the anterior superior iliac crest of the subject. At the same time, the horizontal frame 204 can drive the left and right test components 6 on it to rise and fall synchronously, so that the left and right test components 6 correspond to the greater trochanter of the femur of the subject. The height of the left and right test components 6 can be adjusted by the second height adjustment component 5, so that the left and right test components 6 correspond to the greater trochanter of the femur of the subject.

[0034] Specifically, before the SwayDA test begins, the subject must wear loose sportswear, stand barefoot on the support plate 101 with the ischial tuberosity and heel in a straight line, and look straight ahead at the wall 3 meters away.

[0035] During the test, the subject actively swung his body as required (keeping the head position unchanged, swinging the entire torso in an inverted pendulum-like manner, with the axis of swing at the ankle joint, rather than just swinging the hips), and stopped and swung back to the neutral position after contacting the left and right test components 6 or the front and back test components 3.

[0036] Before formally collecting data, four positions were set for the subject in the forward and backward directions, with the forward and backward swing preset to 2cm, 2.5cm, 3cm and 3.5cm; four positions were set for the subject in the left and right directions, with the left and right swing preset to 4cm, 4.5cm, 5cm and 5.5cm respectively. The subject needed to familiarize himself with the different swing amplitudes in the order from position 1 to position 4, for a total of 3 rounds.

[0037] The test then begins, and the subjects are required to judge different swing amplitudes without being allowed to modify their judgments; the total number of tests is 40, that is, 10 times for each position, and the order in which the positions appear is random.

[0038] Maintain a quiet testing environment. Each test session lasts approximately 10 minutes. The order of testing for forward / backward and left / right limbs is randomized. Subjects may rest for 1 minute between tests to avoid fatigue.

[0039] By requiring subjects to differentiate and perceive the amplitude of active forward / backward (AP) and left / right (ML) posture swings, and by using four preset swing ranges and sensors to collect data (with an accuracy of 0.001), the assessment task is made closer to real posture control scenarios. At the same time, it can capture the somatosensory sensitivity of two spatial dimensions, avoiding the information loss of single-direction assessment, and providing multidimensional data support with high reliability and validity for clinical diagnosis and efficacy evaluation.

[0040] It is worth noting that an adjusting cylinder a is also provided between the horizontal frame 204 and the corresponding left and right test components 6. The horizontal position of the left and right test components 6 can be adjusted by the adjusting cylinder a, so as to meet the test requirements of the subject to swing to different positions in the left and right directions.

[0041] It is also worth noting that the staff can control the start and stop of the first height adjustment component 2, the horizontal adjustment component 4 and the second height adjustment component 5 by operating the control and display module 106. At the same time, it can receive the test data from the front and rear test components 3 and the left and right test components 6 and display the test data in real time, so that the staff can understand the test progress in real time.

[0042] It is also worth noting that the support plate 101 is symmetrically provided with several moving wheels at its bottom. The moving wheels facilitate the flexible movement of the tester, which can meet the placement requirements of different positions. At the same time, the tester is small in size, which is convenient for portable screening and long-term tracking monitoring.

[0043] In one embodiment of the present invention, see Figures 1-2 The first height adjustment component 2 includes a screw a202 rotatably disposed inside the protective frame a103. The screw a202 is threadedly connected to the lifting frame a203, and one end of the screw a202 is connected to the motor a201.

[0044] In this embodiment, when it is necessary to adjust the height of the front and rear test components 3 or the corresponding left and right test components 6, the motor a201 drives the screw a202 to rotate. The screw a202 drives the horizontal frame 204 to move up or down synchronously through a threaded connection with the lifting frame a203 and a sliding connection between the lifting frame a203 and the protective frame a103. The horizontal frame 204 drives the front and rear test components 3 and the corresponding left and right test components 6 at both ends to move up or down synchronously through a connection with the horizontal adjustment component 4. The height of the front and rear test components 3 and the corresponding left and right test components 6 can be adjusted so that the front and rear test components 3 can be adjusted to a height corresponding to the anterior superior iliac spine of the subject. At the same time, the corresponding left and right test components 6 correspond to the greater trochanter of the femur of the subject, which meets the somatic sensation detection needs at different heights and improves the practicality of the device.

[0045] It is worth noting that the motor a201 and screw a202 can be replaced by a hydraulic cylinder. The movable end of the hydraulic cylinder is connected to the end of the lifting frame a203 away from the horizontal frame 204. The hydraulic cylinder drives the lifting frame a203 to move up or down synchronously by extending or retracting, thereby realizing the synchronous lifting and lowering of the horizontal frame 204.

[0046] In one embodiment of the present invention, see Figures 1-5 The front and rear test assembly 3 includes a connecting cylinder a301. A plurality of through grooves a are opened at equal angles on one side wall of the connecting cylinder a301. A sliding contact strip 302 is slidably arranged in the through grooves a. A connecting frame 303 is provided inside the connecting cylinder a301. A plurality of pressure sensors a304 corresponding one-to-one with the sliding contact strips 302 are provided on the side wall of the connecting frame 303. A spring a305 is connected between the pressure sensor a304 and the sliding contact strip 302.

[0047] In this embodiment, in the initial state, the outer wall of the contact slider 302 protrudes from the outer wall of the connecting cylinder a301. At this time, the spring a305 is at its original length, and the pressure value detected by the pressure sensor a304 does not change.

[0048] When the subject needs to be tested in the forward and backward directions, the subject's entire body swings like an inverted pendulum. When the corresponding part of the subject begins to contact the corresponding position of the contact slider 302 on the connecting cylinder a301, the contact slider 302 slides into the connecting cylinder a301 through a sliding connection with the connecting cylinder a301. The spring a305 is stressed and contracts, which transmits the pressure to the pressure sensor a304. The pressure sensor a304 transmits the detected data to the control and display module 106. The control and display module 106 receives and processes the detected data and displays the test results in a timely manner, so that the staff can understand the test results.

[0049] By receiving pressure data from pressure sensors a304 at different locations and judging the changes in pressure data from the corresponding pressure sensors a304, the sensory response speed of different areas on the front and back sides of the subject can be determined, making the sensory detection of the corresponding parts of the subject more accurate, avoiding the inability to meet the sensory testing needs of different parts, and improving the applicability of the device.

[0050] It is worth noting that at least three of the contact sliders 302 are provided, and the contact sliders 302 are equidistantly distributed on the side of the connecting cylinder a301 that are close to each other. This avoids the problem of decreased detection accuracy caused by sudden external collisions or scrapes to the contact sliders 302, which can effectively improve detection accuracy. In addition, it can effectively protect the contact sliders 302 and improve the utilization rate of the contact sliders 302.

[0051] It is also worth noting that the length of the contact slider 302 is 30-70cm, which can effectively meet the forward and backward sensory testing needs of subjects with different widths.

[0052] In one embodiment of the present invention, see Figures 1-4 and Figure 6 The horizontal adjustment assembly 4 includes sliding seats 402 slidably disposed at both ends of the horizontal frame 204. Electric cylinders 401 connected to corresponding sliding seats 402 are respectively provided on the side wall of the horizontal frame 204 near the protective frame a103. A connecting cylinder b403 is installed on the side of the sliding seat 402 away from the protective frame a103. The outer end of the connecting cylinder b403 is provided with a stepped annular groove corresponding to the end of the contacting slide bar 302. Corresponding clips are provided on both the connecting cylinder b403 and the connecting cylinder a301. The connecting cylinder b403 has symmetrically arranged sliding blocks 404 that are movably connected to the slot. One end of the sliding block 404 is provided with a sliding post 405. The end of the connecting cylinder b403 away from the connecting cylinder a301 is provided with a T-shaped plate 406. The T-shaped plate 406 has symmetrically arranged inclined grooves that slide with the sliding post 405. One end of the T-shaped plate 406 penetrates the bottom of the connecting cylinder b403. A spring b407 is provided between the inner wall of the connecting cylinder b403 and the T-shaped plate 406.

[0053] In this embodiment, in the initial state, the sliding block 404 is connected to the slot on the connecting cylinder b403 and the slot on the connecting cylinder a301 respectively. At this time, the T-shaped plate 406 is at the lowest point, the spring b407 is at its original length, and the distance between the symmetrically arranged sliding blocks 404 is at its maximum value.

[0054] During testing, the positions of the front and rear test components 3 need to be adjusted. The electric cylinder 401 drives the sliding seat 402 to slide along the length of the horizontal frame 204 by connecting with the sliding seat 402 and sliding the sliding seat 402 and the horizontal frame 204. The sliding seat 402 adjusts the position of the front and rear test components 3 by connecting with the front and rear test components 3, which can meet the front and rear sensory test of the subject at different positions.

[0055] When it is necessary to disconnect the sliding seat 402 and the front and rear test components 3, push the T-shaped plate 406 upward, the spring b407 is stressed and retracts. At the same time, the T-shaped plate 406 drives the two sliding blocks 404 to move closer to each other by sliding the inclined groove with the sliding column 405 and sliding the sliding block 404 with the connecting cylinder b403. The sliding block 404 disconnects the connection between the connecting cylinder a301 and the connecting cylinder b403 by moving away from the slot on the connecting cylinder a301. Then, pull the connecting cylinder a301 outward to separate the sliding seat 402 and the connecting cylinder a301, which makes it easier for the subject to get on or off the support plate 101. It can realize the quick disassembly and assembly of the connecting cylinder b403 and the connecting cylinder a301, and facilitate the storage and protection of the front and rear test components 3 after testing.

[0056] Furthermore, the ends of the sliding blocks 404 that are far apart from each other may be provided with an inclined surface that is inclined away from the sliding seat 402. The inclined surface facilitates the quick connection of the end of the connecting cylinder a301 onto the stepped annular groove of the connecting cylinder b403, thereby realizing a quick connection between the connecting cylinder a301 and the connecting cylinder b403.

[0057] It is worth noting that the sliding block 404 is designed as a long strip plate. The stability of the connection between the connecting cylinder a301 and the connecting cylinder b403 can be improved by the cooperation between the long strip plate and the corresponding slot.

[0058] In one embodiment of the present invention, see Figures 1-2 The second height adjustment component 5 includes a screw b502 rotatably disposed inside the protective frame b105. The screw b502 is threadedly connected to the lifting frame b503. One end of the screw b502 is connected to the motor b501. An adjustment module is provided between the lifting frame b503 and the support slide rod 504.

[0059] In this embodiment, when the height of the corresponding left and right test components 6 needs to be adjusted, the motor b501 drives the screw b502 to rotate. The screw b502 drives the lifting frame b503 to move up or down synchronously through a threaded connection with the lifting frame b503 and a sliding connection between the lifting frame b503 and the protective frame b105. The lifting frame b503 drives the left and right test components 6 located at its end to move up or down synchronously through a connection with the support slide rod 504. This allows the left and right test components 6 to be adjusted to a height corresponding to the greater trochanter of the femur of the subject, meeting the somatic sensation detection needs at different heights and improving the practicality of the device.

[0060] It is worth noting that the adjustment module includes several limiting holes equidistantly distributed on the support slide rod 504. The lifting frame b503 is slidably provided with a limiting rod that is movably connected to the limiting holes. When it is necessary to adjust the horizontal position of the left and right test components 6, the limiting rod is pulled up to release the cooperation between the limiting rod and the limiting hole, thereby releasing the fixation of the support slide rod 504. Through the sliding between the lifting frame b503 and the support slide rod 504, the horizontal position of the left and right test components 6 set at the end of the support slide rod 504 can be adjusted, which can meet the swing detection needs of the subject in different positions from left to right. When the left and right test components 6 move to the corresponding position, the limiting rod is released, and the bottom of the limiting rod cooperates with the corresponding limiting hole to fix the position of the support slide rod 504 at that position, thereby fixing the position of the corresponding left and right test components 6.

[0061] In addition, the adjustment module can also be configured as an adjustment cylinder b connected to the end of the support slide 504 away from the left and right test components 6. By controlling the extension and retraction of the adjustment cylinder b, the horizontal position of the support slide 504 can be adjusted, thereby adjusting the horizontal position of the corresponding left and right test components 6, thus satisfying the flexible adjustment of different positions of the left and right test components 6.

[0062] In one embodiment of the present invention, see Figures 1-2 , Figures 7-8 The left and right test components 6 include a connecting plate 601 disposed at one end of the horizontal frame 204 and the support slide rod 504 close to each other. The outer end of the connecting plate 601 is provided with a frustum portion 602. Pressure sensors b603 are provided on the outer middle part of the frustum portion 602 and on several inclined surfaces. The outer end of the connecting plate 601 is connected to a hemispherical arc cover 604. The hemispherical arc cover 604 has slots that correspond one-to-one with several pressure sensors b603. A sliding contact frame 605 is slidably disposed in the slot. A spring c606 is connected between the pressure sensor b603 and the sliding contact frame 605.

[0063] In this embodiment, in the initial state, the outer surface of the contact slide 605 protrudes beyond the outer surface of the hemispherical arc cover 604, and the spring c606 is at its original length.

[0064] During the left and right side sensory tests, the subject's entire body swings in an inverted pendulum-like motion. When the corresponding part of the subject begins to contact the corresponding contact slide 605 on the hemispherical cover 604, the contact slide 605 slides inward to the inside of the hemispherical cover 604 through a sliding connection with the hemispherical cover 604. The spring c606 is stressed and contracts, which transmits the pressure to the pressure sensor b603. The pressure sensor b603 transmits the detected data to the control and display module 106. The control and display module 106 receives and processes the detected data and displays the test results in a timely manner, making it convenient for staff to understand the test results.

[0065] By receiving pressure data from the sliding frame 605 at different locations and judging the changes in the corresponding pressure data of the sliding frame 605, the sensory reaction speed of different areas on the left and right sides of the subject can be determined, making the sensory detection of the corresponding parts of the subject more accurate, avoiding the inability to meet the sensory testing needs of different parts, and improving the applicability of the device.

[0066] It is worth noting that the frustum 602 can be configured as a regular polyhedron, with several pressure sensors b603 corresponding one-to-one with several inclined surfaces of the regular polyhedron. This can specifically divide the test area on the left and right sides of the subject into multiple regions. By receiving pressure data and pressure changes from the pressure sensors b603 in different regions, more accurate sensory tests can be performed on different parts of the left and right sides of the subject, which can effectively improve the test accuracy of different parts of the left and right sides of the subject.

[0067] It is also worth noting that the outer wall of the connecting plate 601 near the truncated pyramid 602 may be provided with an external thread, and the circular opening of the hemispherical cover 604 is provided with an internal thread that is threaded to the external thread.
