[0005] Technical problems to be solved

[0006] The purpose of this invention is to provide a pediatric neurotactile examination device and method to solve the problems mentioned in the background art.

[0007] Technical solution

[0008] A pediatric neurotactile examination device includes a detection unit and an identification unit. Two sets of detection units are connected in series through the identification unit. Each detection unit includes a detection box and a supporting base plate disposed in the inner cavity of the detection box. A first detection mechanism and a second detection mechanism are interspersed at the interval between the supporting base plate and the detection box. The side end faces of the two sets of detection boxes are connected in series through the identification unit.

[0009] Preferably, the detection box includes an outer frame box and hollow cavities opened on both sides of the outer end face of the outer frame box. Support columns are arranged in the inner cavity of the hollow cavity. An opening cavity is opened at the top of the outer frame box. The two sides of the top of the outer frame box are movably connected to the cover plate through hinges.

[0010] Preferably, a first detection mechanism and a second detection mechanism are arranged vertically side by side directly above the supporting base plate, and a positioning plate is provided at the top of the first detection mechanism and the second detection mechanism, with the upper end surface of the positioning plate abutting the bottom of the cover plate.

[0011] Preferably, the first detection mechanism includes a connecting block and a rotating shaft movably disposed in the middle of the connecting block. A first rotating disk is sleeved on the outer surface of the rotating shaft, and a contact extension rod is arranged in a circular array on the outer end face of the first rotating disk.

[0012] Preferably, the first detection mechanism further includes a second rotating disk. The outer end face of the rotating shaft is fitted with the second rotating disk. The outer end face of the second rotating disk is provided with an outward extension rod in a circular array. The outer end of the outward extension rod is provided with a touch block. During the detection process, the touch block and the touch outward extension rod collide and strike each other. Because the positions of the touch outward extension rod and the touch block at the upper and lower ends are opposite, the generated sound is transmitted to the child's ear synchronously. Since the two sets of detection units each have a first detection mechanism and a second detection mechanism, there are detection points in front of the left, behind the left, behind the right, and in front of the right respectively. During the process of the external motor driving the whole device to rotate, the child can hear stereo sound during the detection. Before the detection, the child is given detection guidance in advance. During the test, the child points to the place where the sound is the loudest and the test is repeated multiple times. The sound detection result is based on the child's multiple finger pointings to test whether the child's auditory nerves are consistent.

[0013] Preferably, the second rotating disk of the first detection mechanism is positioned above the first rotating disk, and the second rotating disk of the second detection mechanism is positioned below the first rotating disk. The maximum diameter of the contact block and the contact extension rod between the first and second detection mechanisms are in contact with each other. Multiple sets of illumination lamps are arranged in a fan shape at an angle above the overall device, and the light from the lamps converges at the reflector. The child to be tested walks inward to the interval between the two sets of detection units and looks at the side end face of the marking unit. An external motor is connected to the top of the connecting block directly above, and the external motor drives the rotating shaft to rotate. The first and second detection mechanisms rotate relative to each other. When the external drive motor drives the first and second detection mechanisms to rotate in different directions, the arranged contact block and the contact extension rod can strike each other. The image deviation and sound caused by the two striking each other are used to conduct a dual test of sound and image on the child being tested.

[0014] Preferably, the touch block is a component made of synthetic rubber, and the touch extension rod is a component made of alloy material.

[0015] Preferably, the marking unit includes a marking plate and a reflective substrate arranged in a ring array on the side end face of the marking plate. A reflector is arranged between the four sets of reflective substrates. Because the light shines in a fan shape through the gaps of the support column, an external drive motor drives the first detection mechanism and the second detection mechanism to rotate. Because the first detection mechanism and the second detection mechanism have many components, light afterimages will be generated at the light passage points during the rotation process, and the light afterimages will be reflected on the side end face of the marking plate. When the child is standing, he observes the light in the four sets of reflective substrates. Although the light does not shine directly, the brightness reflected on the surface of each reflective substrate should be consistent. Before the test, the child is given test guidance. In the test of light-sensitive areas, he points to the brightest reflective area and performs multiple tests. The light sensitivity test result is the reflective substrate that the child repeatedly points to as the maximum light intensity, and the test detects whether the degree to which each area of ​​the child's visual nerve can withstand strong light is consistent.

[0016] A method for examining pediatric neurotactile sensation using a device includes the following steps:

[0017] S1: Multiple sets of illumination lamps are arranged in a fan shape at a 45-degree angle above the overall device. The light from the lamps converges at the reflector. The child to be tested walks inward to the interval between the two sets of detection units and looks at the side end of the marking unit. The external motor is connected to the top of the connecting block directly above. The external motor drives the rotating shaft to rotate. The first detection mechanism and the second detection mechanism rotate relative to each other. When the external drive motor drives the first detection mechanism and the second detection mechanism to rotate in different directions, the arranged touch blocks and the touch extension rods can strike each other. The image deviation and sound caused by the two striking each other are used to conduct a dual test of sound and image on the child being tested.

[0018] S2: During the testing process, the touch block and the touch extension rod collide and strike each other. Because the touch extension rods at the upper and lower ends are in opposite positions to the touch block, the resulting sound is transmitted to the child's ears synchronously. Since there is a first detection mechanism and a second detection mechanism in the two sets of detection units, there are detection points in front of the left, behind the left, behind the right, and in front of the right. During the process of the external motor driving the whole device to rotate, the child can hear stereo sound during the test. Before the test, the child is given testing guidance in advance. During the test, the child points to the place where the sound is the loudest and the test is repeated. The sound test result is based on the child's multiple finger pointing to test whether the child's auditory nerves are consistent.

[0019] S3: As the light shines in a fan shape through the gaps in the support columns, the external drive motor drives the first and second detection mechanisms to rotate. Because the first and second detection mechanisms have many components, light afterimages will be generated at the points where the light passes during the rotation. The light afterimages will be reflected on the side surface of the signboard. While standing, the child observes the light in the four sets of reflective substrates. Although the light is not directly shining, the brightness reflected on the surface of each reflective substrate should be consistent. Before the test, the child is given test guidance. During the test of light-sensitive areas, the child points to the brightest reflective area and performs multiple tests. The light sensitivity test result is the reflective substrate that the child repeatedly points to as the maximum light intensity, which tests whether the degree of strong light that each area of ​​the child's visual nerve can withstand is consistent.

[0020] Beneficial effects

[0021] Compared with the prior art, the advantages of this invention are:

[0022] 1. Multiple sets of illumination lamps are arranged in a fan shape at a 45-degree angle above the overall device. The light from the lamps converges at the reflector. The child to be tested walks inward to the interval between the two sets of detection units and looks at the side end of the marking unit. The external motor is connected to the top of the connecting block directly above. The external motor drives the rotating shaft to rotate. The first detection mechanism and the second detection mechanism rotate relative to each other. When the external drive motor drives the first detection mechanism and the second detection mechanism to rotate in different directions, the arranged touch blocks and touch extension rods can strike each other. The image deviation and sound caused by the two striking each other are used to conduct a dual test of sound and image on the child being tested.

[0023] 2. During the testing process, the touch block and the touch extension rod collide and strike each other. Because the touch extension rods at the upper and lower ends are in opposite positions to the touch block, the resulting sound is transmitted synchronously to the child's ears. Since the two sets of testing units each have a first and a second testing mechanism, there are testing points at the child's left front, left rear, right rear, and right front. As the external motor drives the entire device to rotate, the child can hear near-stereo sound during the test. Before the test, the child is given testing guidance and is asked to point to the location where the sound is strongest during the test. Multiple tests are conducted, and the sound test results are based on the child's multiple finger pointings to test whether the child's auditory nerves are consistent.

[0024] 3. Because the light shines in a fan shape through the gaps in the support columns, the external drive motor drives the first and second detection mechanisms to rotate. Because the first and second detection mechanisms have many components, light afterimages will be generated at the points where the light passes during the rotation. The light afterimages will be reflected on the side surface of the signboard. While standing, the child observes the light in the four sets of reflective substrates. Although the light is not directly shining, the brightness reflected on the surface of each reflective substrate should be consistent. Before the test, the child is given test guidance. During the test of light-sensitive areas, the child points to the brightest reflective area and performs multiple tests. The light sensitivity test result is the reflective substrate that the child repeatedly points to as the maximum light intensity, which tests whether the degree of strong light that each area of ​​the child's visual nerve can withstand is consistent.

[0035] Please see Figures 1-6 The present invention provides a technical solution:

[0036] Example 1

[0037] A pediatric neurotactile examination device includes a detection unit 1 and an identification unit 2. Two sets of detection units 1 are connected in series through the identification unit 2. Each detection unit 1 includes a detection box 11 and a supporting base plate 12 disposed in the inner cavity of the detection box 11. A first detection mechanism 13 and a second detection mechanism 14 are interspersed at the interval between the supporting base plate 12 and the detection box 11. The side end faces of the two sets of detection boxes 11 are connected in series through the identification unit 2.

[0038] The detection box 11 includes an outer frame box 111 and hollow cavities 112 opened on both sides of the outer end face of the outer frame box 111. Support columns 113 are arranged in the inner cavity of the hollow cavity 112. An opening cavity 114 is opened at the top of the outer frame box 111. The two sides of the top of the outer frame box 111 are movably connected to the cover plate 116 through hinges 115. A first detection mechanism 13 and a second detection mechanism 14 are arranged vertically and side by side on the top of the supporting base plate 12. The top of the first detection mechanism 13 and the second detection mechanism 14 are provided with positioning plates 15. The upper end face of the positioning plate 15 is attached to the bottom of the cover plate 116. The first detection mechanism 13 includes a connecting block 131 and a rotating shaft 132 movably arranged in the middle of the connecting block 131. A first rotating disk 133 is sleeved on the outer surface of the rotating shaft 132. Touch extension rods 134 are arranged in a ring array on the outer end face of the first rotating disk 133.

[0039] Example 2

[0040] The first detection mechanism 13 also includes a second rotating disk 135. The outer end face of the rotating shaft 132 is sleeved with the second rotating disk 135. The outer end face of the second rotating disk 135 is provided with an outward extension rod 136 in a circular array. The outer end of the outward extension rod 136 is provided with a touch block 137. During the detection process, the touch block 137 and the touch outward extension rod 134 collide and strike each other. Because the positions of the touch outward extension rod 134 and the touch block 137 at the upper and lower ends are opposite, the generated sound is transmitted to the child's ears synchronously. Since the two sets of detection units 1 each have a first detection mechanism 13 and a second detection mechanism 14, there are detection points in front of the child's left, behind the child's left, behind the child's right, and in front of the child's right. During the process of the external motor driving the whole device to rotate, the child can hear stereo sound during the detection. Before the detection, the child is given detection guidance in advance. During the test, the child points to the place where the sound is the loudest and the test is repeated. The sound detection result is based on the child's multiple finger pointings to test whether the child's auditory nerves are consistent.

[0041] Example 3

[0042] The second rotating disk 135 of the first detection mechanism 13 is positioned above the first rotating disk 133, and the second rotating disk 135 of the second detection mechanism 14 is positioned below the first rotating disk 133. The contact block 137 between the first detection mechanism 13 and the second detection mechanism 14 contacts the maximum diameter of the contact extension rod 134. The contact block 137 is made of synthetic rubber, and the contact extension rod 134 is made of alloy. Multiple sets of illumination lamps are arranged in a fan shape at a 45-degree angle above the overall device, and the light from the lamps converges at the reflector 23. Further processing is required. The child being tested walks inward to the interval between the two sets of testing units 1, looks at the side end of the marking unit 2, and connects to the top of the connecting block 131 directly above the external motor. The external motor drives the rotating shaft 132 to rotate, and the first testing mechanism 13 and the second testing mechanism 14 rotate relative to each other. When the external drive motor drives the first testing mechanism 13 and the second testing mechanism 14 to rotate in different directions, the arranged touch blocks 137 and the touch extension rods 134 can strike each other. The image deviation and sound caused by the two striking each other are used to conduct a dual test of sound and image on the child being tested.

[0043] Example 4

[0044] The marking unit 2 includes a marking plate 21 and a ring array of reflective substrates 22 arranged on the side end face of the marking plate 21. A reflector 23 is arranged between the four sets of reflective substrates 22. Because the light shines in a fan shape through the gaps of the support column 113, the external drive motor drives the first detection mechanism 13 and the second detection mechanism 14 to rotate. Because the first detection mechanism 13 and the second detection mechanism 14 have many components, light afterimages will be generated at the light passage during the rotation process, and the light afterimages will be reflected on the side end face of the marking plate 21. When the child is standing, he observes the light in the four sets of reflective substrates 22. Although the light does not shine directly, the brightness reflected on the surface of each reflective substrate 22 should be consistent. Before the test, the child is given a test guide in advance. During the test of light-sensitive areas, he points to the brightest reflective area and performs multiple tests. The light sensitivity test result is the reflective substrate 22 that the child repeatedly points to as the maximum light intensity, and the test is conducted to see whether the degree of strong light that each area of ​​the child's visual nerve can withstand is consistent.

[0045] A method for examining pediatric neurotactile sensation using a device includes the following steps:

[0046] S1: Multiple sets of illumination lamps are arranged in a fan shape at a 45-degree angle above the overall device. The light from the lamps converges at the reflector 23. The child to be tested walks inward to the interval between the two sets of detection units 1 and looks at the side end of the marking unit 2. The external motor is connected to the top of the connecting block 131 directly above. The external motor drives the rotating shaft 132 to rotate. The first detection mechanism 13 and the second detection mechanism 14 rotate relative to each other. When the external drive motor drives the first detection mechanism 13 and the second detection mechanism 14 to rotate in different directions, the arranged touch blocks 137 and the touch extension rods 134 can strike each other. The image deviation and sound caused by the two striking each other are used to conduct a dual test of sound and image on the child being tested.

[0047] S2: During the testing process, the touch block 137 and the touch extension rod 134 collide and strike each other. Because the touch extension rod 134 at the upper and lower ends is in the opposite position to the touch block 137, the resulting sound is transmitted to the child's ears synchronously. Since the two sets of testing units 1 each have a first testing mechanism 13 and a second testing mechanism 14, there are testing points in front of the child's left, behind the child's left, behind the child's right, and in front of the child's right.

[0048] S3: As the light shines in a fan shape through the gaps in the support column 113, the external drive motor drives the first detection mechanism 13 and the second detection mechanism 14 to rotate. Because the first detection mechanism 13 and the second detection mechanism 14 have many components, light afterimages will be generated at the light passage during the rotation process, and the light afterimages will be reflected on the side end face of the signboard 21.

The child to be tested walks inward to the interval between the two sets of detection units (1), looks at the side end of the label unit (2), and connects the external motor to the top of the connecting block (131) directly above. The external motor drives the rotating shaft (132) to rotate. The first detection mechanism (13) and the second detection mechanism (14) rotate relative to each other. When the external drive motor drives the first detection mechanism (13) and the second detection mechanism (14) to rotate in different directions, the arranged touch blocks (137) and the touch extension rod (134) can strike each other. Through the image deviation and sound caused by the two striking each other, the child is tested for both sound and image.
