Description

Technical Field

[0001] This invention relates to the field of injury testing technology, and in particular to an auxiliary device for spinal cord injury testing. Background Technology

[0002] Spinal cord injury is a disease that seriously threatens human health and quality of life, and is mostly caused by accidents such as traffic accidents, falls from heights, and being hit by heavy objects. The degree and extent of the injury vary greatly. Mild cases may result in partial limitation of limb sensation and motor function, while severe cases can lead to complete paralysis and even affect important physiological functions such as breathing and circulation, causing great physical and mental suffering to patients, as well as imposing a heavy economic burden on families and society.

[0003] Patent CN101856221A discloses a detection system for determining the degree and location of spinal cord injury, comprising a laser, a filtering device, an electroencephalogram (EEG) signal acquisition device, a signal analysis system, and a display device. The laser beam generated by the laser is filtered and then applied to the human body. The EEG signal acquisition device collects the EEG signals from the human body. The signal analysis system processes the EEG signals using a real-time signal processing algorithm and outputs the detection results. The display device displays waveforms and detection results at different stimulation sites. This detection system selectively stimulates only C-fibers, and the recorded signals are solely laser-evoked potentials related to C-fiber stimulation. Therefore, the signals recorded by this system are clearer, simpler in composition, and the assessment of the degree and location of spinal cord injury is more accurate and reliable.

[0004] Although the detection system is more accurate and reliable in judging the degree and location of spinal cord injury, traditional equipment often uses fixed size or limited manual adjustment methods, which cannot accurately adapt to the physiological structure of patients with different body types, from short to tall. As a result, it cannot ensure that individuals can complete the test under optimal conditions and cannot effectively eliminate data deviations caused by equipment compatibility issues. Summary of the Invention

[0005] The spinal cord injury testing auxiliary device provided by this invention solves the problem that traditional equipment often uses fixed size or limited manual adjustment methods, which cannot accurately adapt to the physiological structure of patients of different body types, from short to tall, and thus cannot ensure that individuals can complete the test under optimal conditions, and cannot effectively eliminate the data deviation caused by equipment adaptation problems.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. This spinal cord injury testing aid has a high degree of self-adjustment capability, providing personalized testing plans for patients of different body types. The device's position adjustment system, through the coordinated work of a bidirectional threaded rod and a moving block, achieves linkage adjustment of the seat tilt angle and foot pedal position, ensuring that patients of all body types, from short to tall, can obtain the optimal testing position. The facial fitting mechanism uses temperature-controlled expansion technology, allowing the flexible airbag to adapt to different facial contours, ensuring stable wear of the device while avoiding pressure discomfort. The elastic buffer structure of the head fixation mechanism further ensures wearing comfort and stability. The comprehensive self-adjustment significantly improves the applicability of the device and the patient experience, ensuring that different individuals can complete the test under optimal conditions, effectively eliminating data deviations caused by device compatibility issues.

[0017] 2. This spinal cord injury testing aid enables the simultaneous acquisition and comprehensive evaluation of multimodal physiological parameters, significantly improving the comprehensiveness and accuracy of the test. Through the bioelectrical signal sensor, eye movement tracker, temperature sensor, pressure sensor, and motion sensor integrated into the head-mounted detection system, the device can simultaneously record multidimensional physiological data such as the patient's electromyographic activity, eye movement, skin temperature, pressure distribution, and movement trajectory in the same time dimension. The multimodal data fusion analysis breaks through the limitations of traditional single-parameter evaluation, enabling clinicians to comprehensively grasp the patient's neurological function status from multiple functional dimensions such as movement, sensation, and autonomic nervous system.

[0018] 3. This spinal cord injury testing aid provides comprehensive safety protection for patients with limited mobility through an intelligent safety protection system. The adjustable protection mechanism adopts a precise mechanical locking design. Through the precise cooperation of the positioning pin and positioning hole, the handrail can reliably switch between horizontal support and vertical protection states. When performing high-risk operations such as changing body position, the vertically set handrail forms an effective lateral support barrier, effectively preventing the patient from tilting or slipping. The cooperation between the limiting slider and the limiting guide groove ensures the smoothness and accuracy of all adjustment movements, avoiding the risks caused by accidental movement. The multi-layered safety protection design is particularly suitable for spinal cord injury patients with impaired trunk control, providing reliable safety protection for the entire testing process, allowing medical staff to focus more on the testing operation itself.

[0019] 4. This spinal cord injury testing auxiliary device, integrated into the head-mounted testing system, utilizes a cleaning and maintenance mechanism that, through the cooperation of an atomizing spray head and an automatic cleaning component, can thoroughly clean and disinfect the display unit, preventing cross-infection. The drive device precisely controls the lifting and lowering of the cleaning component along the lead screw, ensuring thorough cleaning. The system automatically records equipment usage time and maintenance history, providing early warnings of consumable replacement needs. This self-maintenance mechanism not only reduces the workload of medical staff but, more importantly, ensures that the equipment is always in optimal working condition, guaranteeing the reliability and repeatability of test results. It is particularly suitable for long-term use in busy clinical environments. Attached Figure Description

Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Please see Figures 1-10 The present invention provides the following technical solution: Example 1: The spinal cord injury testing aid includes a basic shell 1, a body position adjustment system 2, a head-mounted detection system 3, and a safety protection system. A seat body 4 is provided above the base shell 1. Lateral support frames 5 are symmetrically arranged on both sides of the seat body 4. Armrest components 6 are movably arranged in the two lateral support frames 5 respectively. Foot pedal components 9 are provided inside the base shell 1. The body position adjustment system 2 includes a first adjustment mechanism and a second adjustment mechanism disposed inside the base shell 1. The first adjustment mechanism is used to drive the seat body 4 to adjust the height and tilt angle, and the second adjustment mechanism is used to drive the foot pedal component 9 to adjust the front and rear position. The first adjustment mechanism and the second adjustment mechanism work together through a linkage mechanism. The head-mounted detection system 3 includes a head shell 301, a display unit 302 is provided on the inner surface of the head shell 301, a face fitting mechanism 16 and a head fixing mechanism 15 are also provided on the inner side of the head shell 301, and a physiological parameter acquisition module 19 is integrated inside the head shell 301. The physiological parameter acquisition module 19 includes a bioelectric signal sensor 1901, an eye movement tracker 1902 and a temperature sensor 1903. The safety protection system includes an adjustable protection mechanism 7 disposed between the lateral support frame 5 and the handrail component 6. The adjustable protection mechanism 7 has a first working position that puts the handrail component 6 in a horizontal support state and a second working position that puts the handrail component 6 in a vertical protection state. The head-mounted detection system 3 is connected to the body position adjustment system 2 and the safety protection system via a data transmission line, forming a complete auxiliary device for spinal cord injury testing.

[0025] The patient is assisted by a nursing staff to sit on the main seat 4, and the operator starts the entire system through the control terminal integrated into the armrest. First, the body position parameters are set, and the body position adjustment system 2 is activated based on the patient's height and leg length. The drive motor 201 starts working, driving the bidirectional threaded rod 203 to rotate smoothly, causing the two moving blocks 205 to make precise relative movements under the guidance of the limiting slider 207 and the limiting guide slot 206. One moving block 205 precisely adjusts the seat's tilt angle through the support leg 204 and the lifting cylinder 8, simulating different body positions from supine to sitting, for detecting orthostatic hypotension; the other moving block 205 synchronously adjusts the fore-and-aft position of the footrest component 9 through the mounting bracket 202, ensuring that patients of different heights can comfortably place their feet on the footrest component 9. Throughout the adjustment process, the sliding of the limiting slider 207 within the limiting guide slot 206 effectively prevents the moving block 205 from shifting, ensuring smooth movement and accurate positioning.

[0026] The first adjustment mechanism includes two lifting cylinders 8 which are respectively and fixedly arranged at the top of the support legs 204, and the output ends of the lifting cylinders 8 are fixedly connected to the bottom of the seat body 4; the second adjustment mechanism includes a driving motor 201, a bidirectional threaded rod 203 and two moving blocks 205. The driving motor 201 is fixedly installed on the outer wall of the base housing 1, the bidirectional threaded rod 203 is rotatably connected between two corresponding inner walls of the base housing 1, the output shaft of the driving motor 201 is fixedly connected to one end of the bidirectional threaded rod 203, and the two moving blocks 205 are respectively threadedly connected to both ends of the bidirectional threaded rod 203. A support leg 204 is fixedly installed on the top of one moving block 205, and a mounting bracket 202 is fixedly installed on the top of the other moving block 205.

[0027] Limit guiding slots 206 are opened on two corresponding inner walls of the base housing 1, limit sliders 207 are fixedly arranged on corresponding side walls of the two moving blocks 205, and the limit sliders 207 and the limit guiding slots 206 form a sliding fit; the mounting bracket 202 has a "C" - shaped structure, a foot - stepping component 9 is movably installed on the inner bottom wall thereof, a knee - limiting component 11 is movably installed on the inner top wall thereof, and the foot - stepping component 9 and the knee - limiting component 11 are connected to the inner walls of the mounting bracket 202 through a plurality of first elastic elements 10.

[0028] A rotating wheel 13 is rotatably arranged on the side wall of the knee - limiting component 11, hand - holding parts 14 are fixedly arranged at both ends of the rotating wheel 13, and two holding parts 12 are fixedly arranged on one side of the knee - limiting component 11 close to the seat body 4; two guiding rails 208 are fixedly arranged on both the inner top wall and the inner bottom wall of the mounting bracket 202, and two guiding slots 209 which are matched with the guiding rails 208 are opened on both the bottom of the foot - stepping component 9 and the top of the knee - limiting component 11.

[0029] The facial fitting mechanism 16 includes a flexible airbag 1601 and ventilation holes 1602. The flexible airbag 1601 is fitted on both ends of the inner surface of the head shell 301, several ventilation holes 1602 are arranged at the lower end of the inner side of the head shell 301, a nose - avoiding groove 1603 is opened at the middle position of the inner surface of the head shell 301, a nose - supporting pad 1604 is fixedly connected to the upper end inside the nose - avoiding groove 1603, and a mixed gas of carbon dioxide and nitrogen is filled inside the flexible airbag 1601.

[0030] The head fixing mechanism 15 includes a connecting seat 1501, a lower fixing strap 1506, and an upper fixing strap 1507. The connecting seat 1501 is fixedly connected to both sides of the head shell 301. A sliding groove 1502 is provided inside the connecting seat 1501. A sliding block 1503 is slidably connected inside the sliding groove 1502. One end of the sliding block 1503 is fixedly connected to the end of the lower fixing strap 1506. The upper fixing strap 1507 is fixedly connected between the lower fixing strap 1506 and the head shell 301. A fixing bracket 18 is rotatably connected to the outer surface of the sliding block 1503 through a connecting rod.

[0031] A guide rod 1504 is fixedly connected inside the sliding groove 1502, and a sliding block 1503 is slidably connected to the surface of the guide rod 1504; an elastic buffer structure 1505 is provided between the sliding block 1503 and the inner wall of the sliding groove 1502, and the elastic buffer structure 1505 is provided on the surface of the guide rod 1504.

[0032] After the patient's position is adjusted, the operator puts the head-mounted detection system 3 on the patient. First, the head shell 301 is gently placed in front of the patient. The lower fixing strap 1506 and upper fixing strap 1507 of the head fixation mechanism 15 are adjusted. Under the action of the elastic buffer structure 1505, the straps automatically adapt to the size of the patient's head, achieving a comfortable and stable fixation. Then, the operator activates the facial fitting mechanism 16 through the control terminal. The flexible airbag 1601 begins to inflate and expand, closely fitting the contours of the patient's face on both sides. The nasal support pad 1604 accurately supports the bridge of the nose, ensuring both stability and avoiding pressure discomfort. At the same time, the ventilation hole 1602 blows out a warm, humid airflow, which on the one hand relieves the patient's eye fatigue, and on the other hand promotes the uniform expansion of the carbon dioxide and nitrogen mixture in the flexible airbag 1601 due to heating, achieving a more precise facial fit.

[0033] The physiological parameter acquisition module 19 also includes a pressure sensor 1904 and a motion sensor 1905. The head shell 301 is equipped with a data processing unit 20. The data processing unit 20 is electrically connected to the display unit 302, the physiological parameter acquisition module 19, the body position adjustment system 2 and the safety protection system to form an intelligent spinal cord injury detection and assessment system.

[0034] The system first assesses motor function. The display unit 302 clearly displays the instructions, accompanied by animated demonstrations. When the patient performs the movement, multiple sensors work in tandem. The pressure sensor 1904 integrated within the foot pedal component 9 detects changes in plantar pressure distribution in real time, the motion sensor 1905 within the knee limiting component 11 accurately measures the knee flexion angle and movement trajectory, and the bioelectrical signal sensor 1901 simultaneously collects electromyographic signals from the quadriceps and hamstring muscles. All this data is comprehensively analyzed by the data processing unit 20 to generate a quantitative assessment report including muscle strength level, joint range of motion, and muscle coordination.

[0035] After completing the motor function assessment, the system automatically enters the sensory function testing mode. Display unit 302 shows an anatomical atlas of the human lower limb and prompts that the tactile localization test has begun. The operator uses a dedicated tactile stimulator to gently touch specific dermatome areas of the patient's lower limb. The patient controls the screen cursor by operating the rotating wheel 13 to locate the perceived stimulation site. During this process, eye movement tracker 1902 accurately records the patient's visual search trajectory and reaction time, pressure sensor 1904 detects the force of hand manipulation, and the system comprehensively assesses the functional integrity of the sensory conduction pathway. For patients with sensory dysfunction, the system automatically records the specific distribution areas of sensory loss or abnormality.

[0036] Finally, an autonomic nervous system function assessment is performed. The posture adjustment system 2 controls the seat to slowly rise from a supine position to a sitting position at a standard speed. During this period, the temperature sensor 1903 continuously monitors minute changes in the patient's facial skin temperature, and the bioelectrical signal sensor 1901 simultaneously records heart rate variability and skin conductance. The data processing unit 20 analyzes the dynamic response of these physiological parameters during the posture change process using a proprietary algorithm, objectively assessing the regulatory function of the autonomic nervous system and providing important reference for diagnosing neurogenic bladder, bowel dysfunction, etc.

[0037] The adjustable protective mechanism 7 includes a positioning hole 701, a positioning pin 702, a limiting plate 703, a fixed seat 704, a second elastic element 705, and a mounting base 706. The bottom and side walls of the two handrail components 6 are provided with positioning holes 701. The bottom of the two lateral support frames 5 are fixedly installed with fixed seats 704. The bottom of the two fixed seats 704 is slidably provided with positioning pins 702. The top of the two positioning pins 702 slides through the bottom of the lateral support frame 5 and the bottom end of the two positioning pins 702 is fixedly provided with mounting base 706. The rods of the two positioning pins 702 located in the fixed seats 704 are fixedly sleeved with limiting plates 703. The bottom of the two limiting plates 703 and the bottom inner wall of the fixed seat 704 are provided with a second elastic element 705. The second elastic element 705 is sleeved on the outside of the positioning pins 702. The two positioning pins 702 respectively form a cooperating relationship with the adjacent positioning holes 701.

[0038] Throughout the entire examination process, the adjustable protective mechanism 7 remains operational. When a change in position is required, the handrail component 6 remains in a vertical protective state. The positioning pin 702, reliably engaged with the positioning hole 701 on the side of the handrail by the second elastic element 705, forms effective lateral support, preventing accidental tilting of the patient during position changes. This protective mechanism is particularly suitable for patients with impaired trunk control, ensuring the safety of the examination process.

[0039] Example 2: Based on Example 1, the operator first adjusts the handrail component 6 to a horizontal support state, providing a stable working platform for the patient's upper limbs. The display unit 302 presents a virtual nine-hole insert test task, requiring the patient to grasp the gripping part 12 in a specific sequence and rhythm to complete the insertion and extraction actions. During this process, the high-precision pressure sensor 1904 monitors the distribution and variation of grip force of each finger in real time, the motion sensor 1905 records the smoothness and accuracy of the hand movement trajectory at a sampling frequency of 100 times per second, and the bioelectrical signal sensor 1901 simultaneously collects the electromyographic activity patterns of the forearm muscle group. The system uses a proprietary motion analysis algorithm to quantitatively assess the control ability, coordination, and endurance of fine motor skills in the hand, providing an objective basis for vocational rehabilitation assessment.

[0040] The patient's feet are comfortably placed on the footrest component 9, and they execute precise ankle pump movement patterns following the complex rhythmic visual stimuli displayed on the display unit 302. The bioelectrical signal sensor 1901 simultaneously acquires the timing and intensity of electromyographic activity of the tibialis anterior, gastrocnemius, and soleus muscles, while the motion sensor 1905 accurately records the angular changes and movement trajectory of the ankle joint in various motion planes. The data processing unit 20 analyzes the coordination and temporal accuracy of lower limb multi-joint movements using advanced pattern recognition algorithms, paying particular attention to the coordinated contraction patterns of agonist and antagonist muscles, providing detailed quantitative indicators for assessing motor control disorders.

[0041] The system initiates an advanced sensory integration assessment mode. The display unit 302 simultaneously presents two tasks: first, requiring the patient to accurately track randomly moving visual targets on the screen; and second, transmitting tactile stimuli to the patient at different time points via a vibration motor within the knee-limiting component 11, requiring the patient to respond to specific patterns of vibration. The eye-tracker 1902 accurately records fixation stability, saccade accuracy, and smooth tracking motion quality with a high spatial resolution of 0.5 degrees and a sampling rate of 500Hz, while simultaneously recording the patient's reaction time and accuracy to tactile stimuli. This dual-task paradigm effectively assesses the patient's sensory integration processing ability and attention allocation strategies, making it particularly suitable for assessing subtle functional impairments in patients with mild disabilities.

[0042] The adaptive algorithm built into the data processing unit 20 dynamically adjusts the task difficulty based on the patient's real-time performance. When the patient correctly completes three tasks consecutively, the system automatically increases the operating resistance of the rotating wheel 13, raises the motion precision requirements of the foot pedal component 9, or even shortens the task reaction time window. Conversely, when fatigue or decreased accuracy is detected in the patient, the system appropriately reduces the task difficulty to ensure the accuracy of the assessment and the patient's safety. This individualized adaptive assessment mechanism can accurately measure the patient's optimal functional level, providing a reliable basis for developing precise rehabilitation standards.

[0043] Example 3: A cleaning and maintenance mechanism 17 is also provided on the inner side of the head housing 301. The cleaning and maintenance mechanism 17 includes an atomizing nozzle 1701 and a cleaning component 1705. The atomizing nozzle 1701 is located on the upper inner side of the head housing 301. Lifting grooves 1702 are provided on both inner sides of the head housing 301. A drive device 1703 is fixedly connected to the bottom of the lifting groove 1702. A lead screw 1704 is driven to the output end of the drive device 1703. The cleaning component 1705 is threadedly connected to the surface of the lead screw 1704. An absorbent cleaning material is fixedly connected to the surface of the cleaning component 1705 near the display unit 302.

[0044] The system possesses comprehensive self-maintenance capabilities. After each day's use, the cleaning and maintenance mechanism 17 automatically initiates the maintenance program. The atomizing nozzle 1701 sprays certified disinfectant cleaning solution, while the drive unit 1703 precisely controls the cleaning component 1705 to rise and fall along the lead screw 1704, thoroughly cleaning and disinfecting the display unit 302. The system automatically records equipment usage time and maintenance history, providing early warnings of potential consumable replacements to ensure the equipment is always in optimal working condition.
