Description

Technical Field

[0001] The present invention relates to the technical field of pain meters, and in particular to a quantitative pain meter for tenderness. Background Art

[0002] Pain is a subjective feeling, and different people may have different pain reactions to the same stimulus. The main function of an analgesic instrument is to quantify this subjective pain feeling as much as possible. Currently, an analgesic instrument is used in a handheld manner, and the pain threshold is measured by pressing the human body. During the use of a handheld analgesic instrument, since it is manually held and pressed, it is difficult to ensure that the direction of pressure applied each time is completely perpendicular to the test site, and the pressure distribution may be uneven. For example, when measuring the pain threshold of the back muscles, a slight shake or tilt of the hand may cause excessive pressure on one side of the probe and too little pressure on the other side. This cannot accurately reflect the true pain threshold of the part, causing deviations in the measurement results. In view of this, the present invention proposes a quantitative analgesic instrument for tenderness. Summary of the Invention

[0022] like Figures 1 to 3 As shown, the present invention provides a quantitative pain meter for pressure pain, comprising a base plate 1, a test bed 8 mounted on the base plate 1 for a patient to lie on. A pain meter body 6, mounted above the test bed 8, is used to measure the human pain threshold. An emergency stop button is provided on the test bed 8 to control the first air cylinder 715, facilitating immediate stopping of the instrument if the user experiences pain, thereby preventing pressure injuries.

[0023] Specifically, the pain meter includes a first adjustment mechanism 2 mounted on top of a base plate 1. A second adjustment mechanism 3 is mounted on the first adjustment mechanism 2. A third adjustment mechanism 4 is disposed below the second adjustment mechanism 3. A mounting plate 9 is fixedly connected to the bottom of the third adjustment mechanism 4. A pain meter body 6 is disposed on one side of the mounting plate 9. The first adjustment mechanism 2, the second adjustment mechanism 3, and the third adjustment mechanism 4 are used to adjust the position of the mounting plate 9 and the pain meter body 6. The first adjustment mechanism 2, the second adjustment mechanism 3, and the third adjustment mechanism 4 are used to adjust the position of the pain meter body 6, allowing it to detect different locations on the body of people of different body shapes. The pain meter body 6 is prior art and will not be described in detail here.

[0024] The first adjustment mechanism 2 includes a first fixed plate 21 fixedly connected to the top of the base plate 1. Two sets of first sliders 22 are fixedly connected to one side of the first fixed plate 21. The positions of the first fixed plate 21 and the first sliders 22 are fixed. A first slide rail 23 is slidably connected to the first sliders 22. The first slide rail 23 is arranged vertically. The two sets of first slide rails 23 are jointly fixedly connected to a first movable plate 24. The arrangement of the first sliders 22 and the first slide rail 23 ensures smooth movement of the first movable plate 24. A first servo motor 25 is mounted on the side of the first movable plate 24 away from the first fixed plate 21. The first servo motor 25 drives the first movable plate 24 to move synchronously during movement. The output end of the first servo motor 25 is fixedly connected to a gear 26. A rack 27 is provided on one side of the gear 26 to mesh with it. The rack 27 is fixedly connected to the top of the base plate 1. When the first servo motor 25 drives the gear 26 to rotate, it meshes with the rack 27, thereby moving the gear 26 along the length of the rack 27 and driving the first movable plate 24 and the first movable plate 24 to move synchronously.

[0025] The second adjustment mechanism 3 includes a second fixed plate 31 fixedly connected to the top of the first movable plate 24. When the first movable plate 24 moves, it drives the second fixed plate 31 to move synchronously. A second servo motor 32 is installed at the bottom of the second fixed plate 31. The second servo motor 32 moves synchronously with the second fixed plate 31. The output end of the second servo motor 32 is fixedly connected to a first threaded rod 33. The first threaded rod 33 is horizontally arranged. The first threaded rod 33 is rotatably connected to the bottom of the second fixed plate 31. The second servo motor 32 drives the first threaded rod 33 to rotate in place at the bottom of the second fixed plate 31. A first threaded sleeve 34 is threadedly connected to the first threaded rod 33. When the first threaded rod 33 moves, it drives the first threaded sleeve 34 to move along the length direction of the first threaded rod 33. A second movable plate 35 is fixedly connected to the bottom of the first threaded sleeve 34. When it moves, the first threaded sleeve 34 drives the second movable plate 35 to move synchronously. Multiple groups of second sliders 36 are installed on the top of the second movable plate 35. The second sliders 36 are slidably connected to the second slide rails 37. The second slide rails 37 are arranged parallel to the first threaded rod 33. The second slide rails 37 are fixedly connected to the bottom of the second fixed plate 31. The arrangement of the second sliders 36 and the second slide rails 37 makes the movement of the second movable plate 35 smooth.

[0026] The third adjustment mechanism 4 includes a third servo motor 41 mounted at the bottom of the second movable plate 35. The third servo motor 41 moves synchronously with the second movable plate 35. The output end of the third servo motor 41 is fixedly connected to a second threaded rod 42. The second threaded rod 42 is perpendicular to the first threaded rod 33. The second threaded rod 42 is rotatably connected to the bottom of the second movable plate 35. After the third servo motor 41 is started, it drives the second threaded rod 42 to rotate while maintaining its original position at the bottom of the second movable plate 35. A second threaded sleeve 43 is threadedly connected to the second threaded rod 42. When the second threaded rod 42 rotates, it drives the second threaded sleeve 43 to move along the length of the second threaded rod 42. A third movable plate 44 is fixedly connected to the bottom of the second threaded sleeve 43. When the second threaded sleeve 43 moves, it drives the third movable plate 44 to move. The mounting plate 9 is fixedly connected to the bottom of the third movable plate 44. The mounting plate 9 moves synchronously with the third movable plate 44. A plurality of third sliders 45 are mounted on the top of the third movable plate 44 . A third slide rail 46 is slidably connected to the third slider 45 . The third slide rail 46 is arranged parallel to the second threaded rod 42 and is fixedly connected to the bottom of the second movable plate 35 .

[0027] For further information, see Figure 4 and Figure 5The pain meter also includes a detection assembly 5 disposed on one side of the mounting plate 9. The detection assembly 5 is used to clamp the pain meter body 6 and move the pain meter body 6 for detection. The detection assembly 5 includes a mounting box 51. Both sides of the mounting box 51 are fixedly connected to limit blocks 59. Multiple sets of limit rods 58 are slidably connected to the limit blocks 59. The limit rods 58 are fixedly connected to the bottom of the third movable plate 44. The position of the limit rods 58 is fixed, so that the mounting box 51 can move smoothly under the limiting action of the limit rods 58 and the limit blocks 59. A connecting plate 510 is provided at the bottom of the limit rods 58 to prevent the mounting box 51 from falling. A rubber pad is provided at the bottom of the third movable plate 44 at a position corresponding to the mounting box 51 to prevent the mounting box 51 from making abnormal noise when it bounces upward and hits the third movable plate 44, while also protecting the contact surface. An action plate 511 is installed on the side of the limit block 59 away from the mounting box 51. The action plate 511 moves synchronously with the mounting box 51. The mounting box 51 is a box-shaped device with one side open. Two sets of first connecting rods 52 are rotatably connected to the top wall of the mounting box 51. The ends of the first connecting rods 52 facing away from the mounting box 51 are rotatably connected to second connecting rods 53. One end of each set of second connecting rods 53 is rotatably connected to a connecting rod 54. The first and second connecting rods 52, 53 form a parallelogram structure, and when the first and second connecting rods 52, 53 deflect, they drive the connecting rods 54 to move. A linear guide 55 is slidably connected to the connecting rod 54. The linear guide 55 is fixedly attached to the mounting box 51 and serves to limit the position of the connecting rod 54, ensuring smooth movement. The bottom of the connecting rod 54 extends through the mounting box 51 and is fixedly connected to a mounting fixture 56. The pain meter body 6 is clipped onto the mounting fixture 56, which is used to clamp the pain meter body 6. The inner wall of the mounting box 51 is rotatably connected to a push rod motor 57, and the output end of the push rod motor 57 is rotatably connected to the first connecting rod 52 and the second connecting rod 53. When the push rod motor 57 is extended or retracted, it drives the first connecting rod 52 and the second connecting rod 53 to deflect synchronously, thereby driving the connecting rod 54 to move under the limiting action of the linear guide rail 55.

[0028] Furthermore, if Figure 5 and Figure 6As shown in the figure, the above pain tester further includes two sets of detachment components 7, and the detachment components 7 are used to timely remove the pressure on the human body. The detachment component 7 includes a fixed rod 71 slidably connected to the action plate 511. The fixed rod 71 is fixedly connected to the bottom of the third moving plate 44. The bottom of the fixed rod 71 is fixedly connected with a first fixed frame 72. The first fixed frame 72 is arranged in a "U" shape and is fixedly connected to the bottom of the third moving plate 44. The positions of the fixed rod 71 and the first fixed frame 72 are fixed. A push plate 73 is slidably connected to the fixed rod 71 and is arranged below the action plate 511. After the push plate 73 moves upward, it contacts the action plate 511 and pushes the action plate 511 to带动 the installation box 51 to move upward, so that the detection end of the pain tester body 6 is远离 the human body. A first spring 74 sleeved on the outer circle of the fixed rod 71 is arranged between the push plate 73 and the first fixed frame 72. The first spring 74 is used to release elastic force to带动 the push plate 73 to move upward. Two sets of synchronous plates 75 are fixedly connected to the bottom of the push plate 73. The two sets of synchronous plates 75 are symmetrically arranged on both sides of the fixed rod 71. The ends of the two sets of synchronous plates 75 passing through the first fixed frame 72 are jointly fixedly connected with a clamping plate 76. The push plate 73 moves smoothly under the limiting effect of the synchronous plates 75, and at the same time, the clamping plate 76 moves synchronously with the push plate 73. A fixed block 77 is installed at the bottom of the first fixed frame 72, and the position of the fixed block 77 is fixed. A clamping block 78 is slidably connected to the fixed block 77. One end of the clamping block 78 close to the clamping plate 76 is inclined, which is convenient for the clamping plate 76 to挤压 the clamping block 78 to move downward when moving downward, and at the same time, when the clamping plate 76 is located below the clamping block 78, it is limited by the clamping block 78. The clamping block 78 is arranged above the clamping plate 76. One end of the clamping block 78 is fixedly connected with a synchronous piece 79, and the synchronous piece 79 moves synchronously with the clamping block 78. A sliding rod 710 is fixedly connected to the side of the synchronous piece 79 away from the clamping block 78. One end of the sliding rod 710 away from the synchronous piece 79 is fixedly connected with a limiting disc 711. The limiting disc 711 and the sliding rod 710 both move synchronously with the synchronous piece 79. A reset plate 712 is slidably connected to the sliding rod 710. A second spring 713 sleeved on the outer circle of the sliding rod 710 is arranged between the synchronous piece 79 and the reset plate 712. When the clamping block 78 moves, it带动 the synchronous piece 79 to挤压 the second spring 713, so that the second spring 713 can release elastic force to带动 the clamping block 78 to reset. A second fixed frame 714 is arranged outside the first fixed frame 72. The second fixed frame 714 is fixedly connected to the bottom of the third moving plate 44, and the position of the second fixed frame 714 is fixed. A first air cylinder 715 is installed at the bottom of the second fixed frame 714, and the position of the first air cylinder 715 is fixed. The output end of the first air cylinder 715 is fixedly connected to the reset plate 712. The first air cylinder 715 is used to带动 the reset plate 712 to move, which is convenient for推动 the limiting disc 711 to带动 the clamping block 78 to make way, so that the first spring 74 can release elastic force to带动 the push plate 73 and the action plate 511 to move upward. A guide rod 716 is fixedly connected to the side of the second fixed frame 714 close to the reset plate 712, and the position of the guide rod 716 is fixed.A guide piece 717 is slidably connected to the guide rod 716, and the guide piece 717 is fixedly connected to the side of the reset plate 712. The reset plate 712 moves smoothly under the limiting action of the guide rod 716 and the guide piece 717. The two ends of the clamping plate 76 pass through the second fixed frame 714 and slide with it. A second cylinder 718 is installed on both sides of the second fixed frame 714. The output end of the second cylinder 718 is facing the clamping plate 76. After being activated, the second cylinder 718 is used to drive the clamping plate 76 downward, simultaneously driving the push plate 73 downward and compressing the first spring 74 to accumulate elastic force. At the same time, the clamping plate 76 is limited by the clamping block 78.

[0029] In this embodiment, the user lies on the testing bed 8 and activates the first servo motor 25 to adjust the height of the pain meter body 6, the second servo motor 32 to adjust the left and right position of the pain meter body 6, and the third servo motor 41 to adjust the front and back position of the pain meter body 6, thereby bringing the pain meter body 6 close to the designated position on the body. The push rod motor 57 is then activated, causing the output end of the push rod motor 57 to extend, deflecting the first and second connecting rods 52 and 53. Simultaneously, the push rod motor 57 also deflects, driving the connecting rod 54 downward under the restraining action of the linear guide 55. This causes the mounting fixture 56 to move downward and brings the pain meter body 6 close to the body for testing. When the user experiences pain, they actively press the emergency stop button. At this point, the first air cylinder 715 activates, driving the reset plate 712 to move. The reset plate 712 moves under the restraining action of the guide rod 716 and guide plate 717, while the push rod motor 57 stops. The reset plate 712 pushes the limit plate 711 away from the fixed block 77, and through the slide bar 710, drives the synchronization plate 79 and the locking block 78, causing the locking block 78 to move away from above the locking plate 76. At this point, the first spring 74 releases its elastic force, driving the push plate 73 upward. After contacting the action plate 511, it pushes the action plate 511 upward, thereby driving the mounting box 51 upward, allowing the analgesic body 6 to move away from the subject's body surface. This provides a rapid response and prevents pressure injuries to the subject. The data on the analgesic body 6 indicates the subject's pain threshold, and mechanically controlled movement ensures smooth movement, ensuring accurate test results. After the test is completed, the first cylinder 715 is activated to retract, causing the reset plate 712 to reset. The second cylinder 718 is then activated, causing the output end of the second cylinder 718 to extend and push the clamping plate 76 downward. The clamping plate 76, through the synchronizing plate 75, drives the push plate 73 downward and away from the action plate 511, causing the installation box 51 to fall. The limit block 59 presses on the connecting plate 510, and the push plate 73 compresses the first spring 74. After the clamping plate 76 moves downward, it contacts the inclined surface of the clamping block 78, forcing the clamping block 78 toward the reset plate 712, while driving the synchronizing plate 79 to compress the second spring 713. When the clamping plate 76 moves below the clamping block 78, the second spring 713 releases its elastic force, causing the clamping block 78 to reset and limit the clamping plate 76, preventing the first spring 74 from releasing its elastic force. The second cylinder 718 and the output end of the push rod motor 57 then retract, facilitating further testing.

[0030] The above specific embodiment is merely an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
