Description

Technical Field

[0001] The invention relates to the technical field of lower limb myotonia detection, and in particular to a lower limb myotonia detection device. Background Art

[0002] Through mechanical stimulation monitoring, a special mechanical device is used to briefly squeeze or stretch the muscles. Similar to electrical stimulation, the device records the response of the muscles after mechanical stimulation. For example, a small probe with a pressure sensor is used to briefly stimulate the quadriceps. Normal muscles will produce moderate elastic deformation and recovery, while the deformation degree and recovery time of spastic muscles will be abnormal. The spastic state of the muscles is evaluated by observing these changes. Generally, when testing the calf muscles, the calf part of the lower limb needs to be inserted into the interior of the testing device, and the squeezing force is applied to the calf muscles through the internal structure of the testing device. The signal of the calf muscle response is analyzed by the testing device. When testing patients with limited mobility, the patient is generally required to lie on the bed and the calf is covered at the upper and lower ends of the testing device for testing.

[0003] The patient's calf and thigh cannot be straightened due to other medical conditions (such as hip ankylosis, knee osteoarthritis, etc.). When the patient lies on the testing bed, it is difficult for the testing device to completely cover the calf muscle due to the deviation in the angle between the calf muscle and the testing device. Therefore, the patient is required to adjust the posture for testing, which makes it more difficult to perform ankylosis testing on patients with limited mobility, thereby affecting the testing efficiency and increasing the discomfort caused during the test. At the same time, the patient's calf posture is not adjusted properly, making it difficult for the testing device to completely cover the calf muscle, affecting the testing effect. The present application provides a lower limb muscle stiffness detection device to meet the needs. Summary of the invention

[0015] Optionally, a lifting frame is rotatably connected to the bottom of the rotating connecting frame, and the ends of the lifting frame on opposite sides away from the rotating connecting frame are rotatably connected to the ends of the two pulling bars away from the adapter frame. The lower detection structure is used in correspondence with the upper detection structure, and the lower detection structure is distributed between the two T-shaped rotating shafts.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] The two U-shaped frames are connected to the two L-shaped frames, and the two mounting brackets are connected to the two L-shaped frames, so that the two mounting brackets can be adjusted accordingly. The upper and lower parts of the body are in a right-angled posture as a whole, so that the calf is parallel to the examination bed, so that after the upper detection structure and the lower detection structure are aligned, the upper detection structure and the lower detection structure can cooperate to cover the patient's calf muscle between the two T-shaped rotating shafts for detection. In this way, the calf of the patient who cannot straighten the calf and thigh due to diseases such as hip ankylosis and knee osteoarthritis can be placed in an approximate position, and the posture of the patient's calf is automatically adjusted when the upper detection structure approaches the lower detection structure to cover the calf muscle, so that the patient's calf muscle is placed in parallel between the upper detection structure and the lower detection structure for detection, reducing the difficulty of adjusting the posture of the patient's body and lower limbs, thereby improving the efficiency of lower limb muscle stiffness detection, and at the same time reducing the discomfort caused by the patient's leg adjustment before detection, and reducing the phenomenon that the upper and lower detection structures are difficult to completely cover the calf muscle due to inadequate adjustment of the patient's calf posture, thereby avoiding affecting the detection effect.

[0018] The main body controls the internal driving component to drive the additional adjustment frame to slide up and down in the height adjustment slot. Therefore, before the test, the operator can adjust the overall height of the additional adjustment frame and the connecting strip according to the length of the patient's thigh to avoid the calf between the upper detection structure and the lower detection structure being unable to be parallel to the upper detection structure when the U-shaped frame lifts the calf due to the longer length of the patient's thigh. When the patient lies on the examination bed, the legs are placed on each set of placement frames, so that the placement frame away from the end of the main body is close to the joint of the patient and the calf, and at the same time, the outer wall of the patient's calf away from the knee joint is placed on the placement frame close to the end of the main body, so that the position of the patient's calf muscle is between the two placement frames in each group, and then the motor drives the extension strip to rotate between the two matching frames to drive the upper detection structure The upper detection structure gradually approaches the position of the lower detection structure. When the upper detection structure is parallel to the lower detection structure, the extension bar and the upper detection structure are controlled to descend by the automatic telescopic rod, and the calf muscle of the lower limb is covered between the lower detection structure and the upper detection structure in cooperation with the lower detection structure. The calf muscle is tested for muscle rigidity through the cooperation of the lower detection structure and the upper detection structure, thereby facilitating the detection of patients with limited mobility. When the patient's calf is placed on the placement rack, if the patient's calf is relatively thick, the arc surface on the buffer block will be squeezed, so that the buffer block slides inside the buffer groove and squeezes the arc block, thereby increasing the distance between the buffer block and the placement rack, making the placement rack and the arc surface on the buffer block fit the patient's calf better, further improving the comfort of the patient's legs during the detection process, thereby improving the practicality of the device.

[0019] When the sliding frame is pushed to move by the double-headed connecting strip and the connecting round rod, the adapter frame is simultaneously pushed to slide relatively in the second strip hole. The two ends of the lifting frame are respectively connected to the rotating connecting frame and the two pulling bars away from the end of the adapter frame, so that the angle between the lifting frame and the pulling bar can gradually increase when the adapter frame drives the pulling bar to move synchronously. The lower detection structure is slidingly connected with the rising sliding hole through two sliding blocks to push the lower detection structure to rise as a whole, so that the lower detection structure can be synchronously raised in the process of the upper detection structure gradually approaching the calf, thereby improving the tightness of the lower detection structure and the upper detection structure to clamp the patient's calf, and at the same time avoiding the situation that when the U-shaped frame lifts the patient's calf, the height of the lower detection structure is lower than the U-shaped frame and cannot contact the patient's calf, which affects the tightness of the upper detection structure and the lower detection structure to cover the patient's leg and affects the detection.

[0038] like Figures 1 to 6As shown, the support mechanism 3 is arranged between the two matching frames 204, and the support mechanism 3 includes two sliders 301, and the two sliders 301 are respectively slidably connected to the inside of the two lower pressure holes 203, and a contact roller 302 is fixedly connected between the two sliders 301, and an L-shaped frame 303 is fixedly connected to the center of the outer wall of the contact roller 302, and the end of the L-shaped frame 303 away from the contact roller 302 is rotatably connected to a double-headed connecting strip 304, and the double-headed connecting strip 304 is away from the L-shaped frame 3 One end of 03 is fixedly connected with a connecting rod 305, and the two opposite sides of the connecting rod 305 are fixedly connected with a through slide 306, and the two through slides 306 are fixedly connected with a rack 307 on the side away from the double-headed connecting strip 304. The support mechanism 3 also includes two adapter frames 308, and the two adapter frames 308 are rotatably connected to the bottom of the two through slides 306, and the end of the adapter frame 308 away from the through slide 306 is fixedly connected with a pulling bar 309, and the rack 307 slides through the protective shell 206, the gear 402 is meshed with the rack 307, the two penetrating slides 306 slide through the two bar holes 208 respectively, the outer wall of the contact roller 302 is used in correspondence with the two extension strips 212, and the two sliders 301 are pushed to slide downward inside the two pressing holes 203 respectively, and the tension spring between the slider 301 and the top of the pressing hole 203 is stretched, so that the contact roller 302 can slide down in a straight line, through the angle between the L-shaped frame 303 and the double-headed connecting strip 304 Less than 70 degrees, as the contact roller 302 gradually drops after being pressed, the angle between the L-shaped frame 303 and the double-headed connecting strip 304 will gradually decrease, thereby pushing the double-headed connecting strip 304 to slide in the direction of the main body 1, pulling the connecting round rod 305 to slide synchronously inside the two bar-shaped holes 208, thereby driving the two racks 307 to slide synchronously inside the two protective shells 206 respectively through the penetrating slide 306 at both ends of the connecting round rod 305, and driving the gear 402 inside the protective shell 206 to rotate;

[0039] like Figures 1 to 7As shown, the placement mechanism 4 is arranged between the two matching frames 204, and the placement mechanism 4 includes two T-shaped rotating shafts 401, and the two T-shaped rotating shafts 401 are rotatably connected between the two matching frames 204 at one end away from the connecting strip 202, and the outer wall of the T-shaped rotating shaft 401 is provided with an extended connecting end, and the extended connecting end of the outer wall of the two T-shaped rotating shafts 401 is rotatably connected with a movable connecting rod 403, and the two movable connecting rods 403 are fixedly connected with a U-shaped frame 404 on the opposite sides, and the tops of the two U-shaped frames 404 are fixedly connected with two groups of placement frames 405, and the two opposite sides of the T-shaped rotating shaft 401 are fixedly connected with a gear 402, and the gear 402 inside the protective shell 206 rotates, driving the two T-shaped rotating shafts 401 to rotate at one end of the two matching frames 204 away from the extension strip 212, and can drive the extended connecting end on each T-shaped rotating shaft 401 to gradually move upward, so that the two movable connecting rods 403 on the extended connecting ends of the two T-shaped rotating shafts 401 are connected to the protective shell 206. The two groups of U-shaped frames 404 connected to the two movable connecting rods 403 move upward away from a corner of the main body 1 as a whole, so that the two placement racks 405 away from the main body 1 and the two buffer blocks 407 are against a part of the patient's calf near the knee joint, so that the patient's thigh and calf can be in a right angle posture as a whole, and the calf is parallel to the examination bed 101, so that after the upper detection structure 213 corresponds to the lower detection structure 503, the upper detection structure 213 and the lower detection structure 503 can cooperate to cover the patient's calf muscle between the two T-shaped rotating shafts 401 for detection. When the patient's calf is placed on the placement rack 405, if the patient's calf is relatively thick, the arc surface on the buffer block 407 will be squeezed, so that the buffer block 407 slides inside the buffer groove 406 and squeezes the arc block 408, so that the distance between the buffer block 407 and the placement rack 405 becomes larger, so that the arc surfaces on the placement rack 405 and the buffer block 407 are more closely fitted to the patient's calf;

[0040] like Figure 1 and Figure 3 As shown, the main body 1 is provided with height adjustment grooves 102 at two locations corresponding to the two connecting strips 202 on one side close to the examination bed 101, the connecting strips 202 are slidably connected to the height adjustment grooves 102, a fitting hole 103 is provided on the top of the examination bed 101, and a bracket 104 is fixedly connected to a location near the fitting hole 103 at the bottom of the examination bed 101, and the main body 1 controls the internal driving component to drive the additional adjustment frame 201 to slide up and down inside the height adjustment groove 102, so that before the test, the operator can adjust the overall height of the additional adjustment frame 201 and the connecting strips 202 according to the length of the patient's thigh.

[0041] By setting the extension bar 212 to rotate between the two matching frames 204, the extension bar 212 and the two rollers on the contact roller 302 will be pressed against each other, pushing the two sliders 301 to slide downward in the two lower pressing holes 203 respectively, and stretching the tension spring between the slider 301 and the top of the lower pressing hole 203, so that the contact roller 302 can slide down in a straight line, and the angle between the L-shaped frame 303 and the double-headed connecting bar 304 is less than 70 degrees. As the contact roller 302 gradually descends after being pressed, the L-shaped frame 303 and the double-headed connecting bar 304 will be pressed. The angle between the head connecting strips 304 gradually decreases, thereby pushing the double-head connecting strip 304 to slide in the direction of the main body 1, pulling the connecting round rod 305 to slide synchronously inside the two bar-shaped holes 208, thereby driving the two racks 307 to slide synchronously inside the two protective shells 206 through the through slides 306 at both ends of the connecting round rod 305, driving the gears 402 inside the protective shells 206 to rotate, driving the two T-shaped shafts 401 to rotate at the ends of the two matching frames 204 away from the extension strip 212, and driving the gears 402 inside the protective shells 206 to rotate. The extended connecting end gradually moves upward, so that the two movable connecting rods 403 on the extended connecting ends of the two T-shaped rotating shafts 401 and the two sets of U-shaped frames 404 connected to the two movable connecting rods 403 move upward away from a corner of the main body 1 as a whole, so that the two placement racks 405 and the two buffer blocks 407 away from the main body 1 are pressed against a part of the patient's calf near the knee joint, so that the patient's thigh and calf are in a right angle posture as a whole, and the calf is parallel to the examination bed 101, so that after the upper detection structure 213 corresponds to the lower detection structure 503, The upper detection structure 213 and the lower detection structure 503 cooperate to cover the patient's calf muscles between the two T-shaped rotating shafts 401 for detection. In this way, the calf of a patient whose calf and thigh cannot be straightened due to conditions such as hip ankylosis and knee osteoarthritis can be placed in an approximate position. When the upper detection structure 213 approaches the lower detection structure 503 to cover the calf muscles, the posture of the patient's calf is automatically adjusted, so that the patient's calf muscles are placed parallel to each other between the upper detection structure 213 and the lower detection structure 503 for detection.

[0042] like Figure 1 , Figure 2 and Figure 6As shown, the matching mechanism 5 includes two sliding blocks 501, and the two sliding blocks 501 are respectively slidably connected inside the two rising sliding holes 207, and a lower detection structure 503 is fixedly connected between the two sliding blocks 501, and a rotating connecting frame 504 is fixedly connected to the side of the lower detection structure 503 close to the main body 1, and a lifting frame 502 is rotatably connected to the bottom of the rotating connecting frame 504, and the ends of the lifting frame 502 on both sides away from the rotating connecting frame 504 are rotatably connected to the ends of the two pulling bars 309 away from the adapter frame 308, and the lower detection structure 503 is used in conjunction with the upper detection structure 213, and the lower detection structure 503 is distributed on two T-shaped rotating shafts. 401, through the rotational connection between the two ends of the lifting frame 502 and the rotating connecting frame 504 and the two pulling bars 309 away from the end of the adapter frame 308, when the adapter frame 308 drives the pulling bar 309 to move synchronously, the angle between the lifting frame 502 and the pulling bar 309 can gradually increase, and the lower detection structure 503 is pushed to rise as a whole through the sliding connection between the two sliding blocks 501 and the rising sliding hole 207, so that the lower detection structure 503 can be synchronously raised in the process of the upper detection structure 213 gradually approaching the calf, thereby improving the tightness of the lower detection structure 503 and the upper detection structure 213 clamping the patient's calf.

[0043] The working principle of the technical solution provided by the present invention is as follows:

[0044] The main body 1 controls the internal driving component to drive the adding adjustment frame 201 to slide up and down inside the height adjustment slot 102. Therefore, before the test, the operator can adjust the overall height of the adding adjustment frame 201 and the connecting strip 202 according to the length of the patient's thigh to avoid the calf between the upper detection structure 213 and the lower detection structure 503 being unable to be parallel to the upper detection structure 213 when the U-shaped frame 404 lifts the calf due to the longer length of the patient's thigh. When the patient lies on the examination bed 101, the legs are placed on each group of placement frames 405, so that the placement frame 405 away from the end of the main body 1 is close to the joint of the patient and the calf, and at the same time, the outer wall of the patient's calf away from the knee joint is placed on the placement frame 405 close to the end of the main body 1, so that the position of the patient's calf muscle is between the two placement frames 405 in each group, and then the motor 214 drives the extension strip 212 to extend between the two placement frames 405 in each group. The two matching frames 204 rotate to drive the upper detection structure 213 to gradually approach the position of the lower detection structure 503. When the upper detection structure 213 is parallel to the lower detection structure 503, the extension bar 212 and the upper detection structure 213 are controlled to descend by the automatic telescopic rod 211, and cooperate with the lower detection structure 503 to cover the calf muscle of the lower limb between the lower detection structure 503 and the upper detection structure 213. The calf muscle is tested for muscle rigidity through the cooperation of the lower detection structure 503 and the upper detection structure 213. When the patient's calf is placed on the placement frame 405, if the patient's calf is relatively thick, the arc surface on the buffer block 407 will be squeezed, so that the buffer block 407 slides inside the buffer groove 406 and squeezes the arc block 408, thereby increasing the distance between the buffer block 407 and the placement frame 405, so that the arc surfaces on the placement frame 405 and the buffer block 407 are more in line with the patient's calf.

[0045] When the double-headed connecting strip 304 and the connecting round rod 305 push the penetrating slide 306 to move, the adapter frame 308 is synchronously pushed to slide relatively inside the second strip hole 209. The two ends of the lifting frame 502 are respectively connected to the rotating connecting frame 504 and the two pulling strips 309 that are away from the end of the adapter frame 308. When the pulling strip 309 is synchronously moved by the adapter frame 308, the angle between the lifting frame 502 and the pulling strip 309 is gradually increased. The lower detection structure 503 is connected to the sliding hole 207 through the sliding connection between the two sliding blocks 501. Then, the lower detection structure 503 is pushed to rise as a whole, so that when the upper detection structure 213 gradually approaches the calf, the lower detection structure 503 can also rise synchronously, thereby improving the tightness of the lower detection structure 503 and the upper detection structure 213 clamping the patient's calf, and at the same time avoiding the situation that when the U-shaped frame 404 lifts the patient's calf, the height of the lower detection structure 503 is lower than the U-shaped frame 404 and cannot contact the patient's calf, affecting the tightness of the upper detection structure 213 and the lower detection structure 503 covering the patient's leg and affecting the detection.
