Description

Technical Field

[0001] This invention relates to the field of spinal detection and physiotherapy technology, and in particular to a spinal detection and physiotherapy bed. Background Technology

[0002] Scoliosis causes an imbalance of force on the left and right sides of the spine, resulting in shoulder misalignment. This can affect the growth and development of adolescents, causing physical deformities. In severe cases, it may affect cardiopulmonary function and even involve the spinal cord, leading to paralysis.

[0003] In the early stages of scoliosis, non-surgical massage and other physical therapy methods can effectively alleviate the curvature. However, the massage and acupressure process largely depends on the doctor's experience. Due to the significant differences in experience among doctors, some physical therapy procedures are not scientific or reasonable enough. Summary of the Invention

[0004] The purpose of this invention is to provide a spinal detection and physiotherapy bed that overcomes the above-mentioned defects, enabling convenient real-time detection and pressure application of the human spinal scoliosis condition, making the scoliosis physiotherapy process more scientific and reasonable.

[0005] To achieve the above objectives, the solution of the present invention is: a spinal detection and physiotherapy method, which utilizes a spinal detection and physiotherapy bed, including a bed frame for a person to lie on. Multiple pressure sensor groups are disposed on the upper surface of the bed frame. Each pressure sensor group includes at least two pressure sensors symmetrically arranged along the width direction of the bed frame. An airbag is disposed above each pressure sensor group. Each airbag is connected to an air source device, which allows each airbag to independently expand by air intake or contract by air exhaust. The air source device and each pressure sensor are communicatively connected to a controller. The method is characterized by the following steps:

[0006] Step 1: Pre-treatment preparation, have the patient lie on the bed above the bed;

[0007] Step 2: Detection, by transmitting the pressure values ​​collected by the pressure sensors of each pressure sensor group to the controller, the tension distribution of the patient's back muscles is obtained;

[0008] Step 3: Before treatment, relax the muscles. The controller controls the air source device to allow the airbags above each pressure sensor group to expand independently and sequentially. Press and push on the patient's back, and repeat this process multiple times.

[0009] Step 4: Press therapy, repeat step 3, and inflate the airbag at the point where the difference in muscle tension between the left and right sides of the patient's back is greater, and press it upwards on the patient's back for a predetermined time;

[0010] Step 5: Relax the muscles after treatment and repeat step 3.

[0011] Furthermore, each of the airbags is equipped with a pressure sensor to detect the air pressure inside each airbag, and each pressure sensor is communicatively connected to the controller, which is communicatively connected to an interactive display.

[0012] Before step 1 begins or after step 5 is completed, the doctor inputs information into the controller to control the inflation of the airbag at the designated location, causing it to bulge upwards from the other airbags.

[0013] The controller displays a virtual motion scene on the interactive display based on the deviation between the air pressure value detected by the air pressure sensor in the corresponding airbag of the convex shape and the preset air pressure value in the controller. When the detected air pressure value is equal to the preset air pressure value, the moving target in the virtual motion scene moves in a straight line. When the detected air pressure value is greater than or less than the preset air pressure value, the moving target in the virtual motion scene moves to both sides, respectively, to prompt the patient to actively adjust the tension of the back muscles, change the pressure acting on the corresponding airbag of the convex shape, and thus change the air pressure in the corresponding airbag of the convex shape, so that the moving target in the virtual motion scene keeps moving in a straight line.

[0014] Furthermore, the bed frame includes a bed frame, a back support frame, and a leg support frame. The back support frame and the leg support frame are arranged sequentially from the head to the foot of the bed frame. Multiple pressure sensor groups are arranged on the back support frame. The end of the back support frame near the leg support frame is laterally pivotally connected to the bed frame, and the end of the leg support frame near the back support frame is laterally pivotally connected to the bed frame.

[0015] In step 1, when the patient is lying down, the back support frame supports the patient's back, and the leg support frame supports the patient's legs.

[0016] In step 2, the back support frame and the leg support frame are rotated around the pivot point. When the back support frame and the leg support frame are both horizontal, and when the angle between the back support frame and the leg support frame is less than 180 degrees, the pressure values ​​are collected by the pressure sensors of the pressure sensor group to obtain the back muscle tension distribution of the patient in the two postures.

[0017] After adopting the above solution, the beneficial effects of the present invention are as follows:

[0018] (1) The patient lies on the bed. Since multiple pressure sensor groups are arranged in sequence between the patient's waist and neck, the pressure values ​​collected by the pressure sensors of each pressure sensor group are transmitted to the controller to obtain the tension distribution of the patient's back muscles. Then, the patient's spinal posture can be inferred from the tension distribution of the patient's back muscles, so as to realize the real-time automatic detection of the patient's spinal posture.

[0019] (2) The controller controls the air source device so that the airbags above each pressure sensor group are independently inflated and pushed up to press on the patient's back to relax the patient's back muscles. After relaxation, when pressing again, the airbags at the positions with large differences in back muscle tension remain for a predetermined time, so as to achieve targeted passive pressure therapy on the patient's back according to the patient's actual condition. The pressure therapy process is more scientific and reasonable. Attached Figure Description

Detailed Implementation

[0027] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] This invention provides a spinal examination and physiotherapy method, which utilizes a spinal examination and physiotherapy bed, such as... Figure 1-6 As shown, the focus here is on combining... Figure 1As shown, the bed includes a bed frame 19 for lying down. The bed frame 19 includes a bed frame 1, a back support frame 2, and a leg support frame 3. The bed frame 1 is located at the bottom of the bed frame 19, resting on the ground. Above the bed frame 1, the back support frame 2 and the leg support frame 3 are arranged adjacent to each other from head to foot. The back support frame 2 supports the upper body, and the leg support frame 3 supports the lower body. Further details are provided. Figure 4 , Figure 6 As shown, the back support frame 2 is laterally pivotally connected to the bed frame 1 at one end near the leg support frame 3. A first flipping drive mechanism 4 connects the back support frame 2 and the bed frame 1, driving the back support frame 2 to flip around the pivot point. The leg support frame 3 is laterally pivotally connected to the bed frame 1 at one end near the back support frame 2, and a second flipping drive mechanism 5 connects the leg support frame 3 and the bed frame 1, driving the leg support frame 3 to flip around the pivot point. The structures of the first flipping drive mechanism 4 and the second flipping drive mechanism 5 are not specifically limited, but are detailed in this embodiment. The first flipping drive mechanism 4 and the second flipping drive mechanism 5 are electric cylinders or pneumatic cylinders. One end of the first flipping drive mechanism 4 is laterally pivoted on the bed frame 1, and the other end is laterally pivoted on the back support frame 2. One end of the second flipping drive mechanism 5 is laterally pivoted on the bed frame 1, and the other end is laterally pivoted on the leg support frame 3. By extending and retracting the first flipping drive mechanism 4 and the second flipping drive mechanism 5, the back support frame 2 and the leg support frame 3 are respectively driven to flip around the pivot point, thereby adjusting the angle between the back support frame 2 and the leg support frame 3, so that the body posture of the patient lying on the back support frame 2 and the leg support frame 3 changes.

[0029] Key points combined Figure 1 , Figure 5As shown, to monitor the spinal posture of a person lying on the bed 19 in real time, multiple pressure sensor groups 6 are provided on the upper surface of the bed 19. Specifically, in this embodiment, the multiple pressure sensor groups 6 are arranged on the back support frame 2, sequentially between the waist and neck of the person. Each pressure sensor group 6 includes at least two pressure sensors 8 symmetrically arranged along the width direction of the bed 19. The number of pressure sensor groups 6 and the number of pressure sensors 8 included in each pressure sensor group 6 are not specifically limited. Specifically, in this embodiment, a total of eight pressure sensor groups 6 are provided, and each pressure sensor group 6 includes two pressure sensors 8. When the upper body of the person lies on the back support frame 2, the central axis of the person coincides with the axis of symmetry in the width direction of the back support frame 2. Then, by monitoring the pressure values ​​generated by various parts of the back on the pressure sensors 8 below, the distribution of muscle tension in the back can be obtained. The left and right deviation of each segment of the human spine is inferred. The pressure sensor 8 can be any existing pressure sensor. Specifically, in this embodiment, each pressure sensor 8 includes a pressure sensor body 9 and a movable plate 10. The movable plate 10 is disposed above the bed frame 19 and moves vertically relative to the bed frame 19. The pressure sensor body 9 is disposed between the movable plate 10 and the bed frame 19. More specifically, the movable plates 10 of two pressure sensors 8 on the same pressure sensor group 6 are adjacent and symmetrically arranged along the width direction of the back support frame 2 and span the entire width of the back support frame 2. The pressure sensor body 9 is connected between the movable plate 10 and the back support frame 2. When the human body presses down on the movable plate 10, the pressure sensor body 9 sandwiched between the movable plate 10 and the back support frame 2 is squeezed. The pressure sensor body 9 collects the pressure value generated when squeezed.

[0030] Further focus on Figure 1 , Figure 2As shown, to perform real-time massage and pressure on the back muscles based on the spine posture of the human body and to achieve interaction with the patient, each pressure sensor group 6 is equipped with an airbag 7. The shape of the airbag 7 is not specifically limited. In this embodiment, the airbag 7 is cylindrical, extending along the width of the bed frame 2 and spanning the width of the bed frame 19. Due to the good flexibility of the human waist, two airbags 7 are stacked on the bed frame 19 at the position corresponding to the human waist. The double-layer airbag design can achieve a better therapeutic effect on the human waist muscles. Each airbag 7 is connected to an air source device, which allows each airbag 7 to independently inflate or deflate. Each airbag 7 is equipped with a pressure sensor to detect the air pressure inside each airbag 7. The air source device and the pressure sensor... All sensors are existing technologies and conventionally configured, and are not shown in the attached drawings. The air source device, each of the pressure sensors 8, and the air pressure sensor are all communicatively connected to a controller 14. The controller 14 is located beside the bed frame 1 and is fixedly connected to the bed frame 1. The controller 14 is also communicatively connected to an interactive display 20. The interactive display 20 can be any type of display device, preferably a VR display device, such as VR glasses, for the patient to wear. The controller 14 is also communicatively connected to a control panel 15 that inputs information to the controller 14. The control panel 15 is set on the controller 14 and displays the curvature of the human spine, enabling interaction with the doctor, so that the doctor can manually adjust the angle between the back support frame 2 and the leg support frame 3, as well as the air pressure of each airbag 7, etc.

[0031] In a preferred embodiment, to detect the pose of the human buttocks, the focus is on combining... Figure 5 As shown, the leg support frame 2 is provided with a plurality of pressure sensor groups 6. The pressure sensor groups 6 on the leg support frame 2 start from the end of the leg support frame 2 near the back support frame 2 and are arranged sequentially towards the end of the leg support frame 2 away from the back support frame 2. In this embodiment, a total of two pressure sensor groups 6 are provided. The structure of each pressure sensor group 6 on the leg support frame 2 is the same as that of each pressure sensor group on the back support frame 2.

[0032] In a preferred embodiment, to accommodate doctors of different heights and facilitate physiotherapy for patients lying on the bed 19, the bed 19 is height-adjustable, specifically in conjunction with... Figure 6As shown, the bed frame 1 includes a floating support 11 and a bed base support 12. The back support frame 2 and the leg support frame 3 are both pivotally connected to the floating support 11. The floating support 11 is vertically movable above the bed base support 12, and the bed base support 12 rests on the ground. A vertical drive mechanism 13 is connected between the floating support 11 and the bed base support 12. The vertical drive mechanism 13 can be any existing mechanism that can provide lifting power, thereby adjusting the height of the bed by raising and lowering the floating support 11. In this embodiment, four guide columns 17 are also longitudinally connected between the floating support 11 and the bed base support 12. The four guide columns 17 are located around the periphery of the vertical drive mechanism 13 to improve the stability of the floating support 11 during the lifting and lowering process.

[0033] In a preferred embodiment, to accommodate different patient heights, the opening positions of the pressure sensor group 6 and the airbags 7 are adaptively adjusted. A laser rangefinder 18 is also provided at the front end of the back support frame 2 on the bed frame 19. The laser rangefinder 18 is communicatively connected to the controller 14. The laser rangefinder 18 illuminates the rear end of the bed frame 19 to detect the position of the patient's shoulders. This allows for a more accurate determination of the opening positions of the pressure sensor group 6 and the airbags 7 during use, based on the patient's height. This ensures the accuracy of the back muscle tension detection by each pressure sensor group 6, enabling the multiple airbags 7 to cover the patient's neck to waist area without affecting the normal placement of the patient's head.

[0034] The method includes the following steps:

[0035] Step 1: Pre-treatment preparation. Have the patient lie on the bed with the back support frame supporting the patient's back and the leg support frame supporting the patient's legs.

[0036] Step 2: Detection. The back support frame and leg support frame are rotated around the pivot point. When the back support frame and leg support frame are both horizontal, and when the angle between the back support frame and leg support frame is less than 180 degrees, pressure values ​​are collected by the pressure sensors of the pressure sensor group. The collected pressure values ​​are transmitted to the controller to obtain the back muscle tension distribution of the patient in two postures. By detecting the back muscle tension distribution of the patient in two postures, the patient's back muscle tension distribution can be reflected more scientifically and reasonably.

[0037] Step 3: Muscle relaxation before treatment. The controller controls the air source device to allow the airbags above each pressure sensor group to expand independently and sequentially. The airbags are then pushed and pressed against the patient's back, and this is repeated multiple times to relax the patient's back muscles and improve the treatment effect of subsequent treatments.

[0038] Step 4: Press therapy. Repeat step 3, and inflate the airbag 7 at the point where the difference in tension between the left and right sides of the patient's back muscles is large, and press it against the patient's back for a predetermined time to achieve passive press therapy on the patient's back muscles. In addition, during the press therapy, it can be targeted according to the actual distribution of tension in the patient's back muscles, making the press therapy process more scientific and reasonable.

[0039] Step 5: Relax the muscles after treatment, and repeat step 3 to complete the passive treatment process.

[0040] In a preferred embodiment, active treatment is performed on the patient before or after the passive treatment described above. Alternatively, only passive treatment or active treatment may be performed. Specifically, before step 1 begins or after step 5 is completed, the doctor inputs information into the controller 14 according to the patient's condition, and controls the airbag 7 at a designated position to inflate and expand, protruding above the other airbags 7.

[0041] The controller displays a virtual motion scene on the interactive display 20 based on the deviation between the air pressure value detected by the air pressure sensor inside the corresponding convex airbag 7 and a preset air pressure value within the controller. When the detected air pressure value is equal to the preset air pressure value, the motion target in the virtual motion scene moves in a straight line. When the detected air pressure value is greater than or less than the preset air pressure value, the direction of movement of the motion target in the virtual motion scene deviates to both sides, prompting the patient to actively adjust the tension of their back muscles, change the pressure acting on the corresponding convex airbag 7, and thus change the air pressure inside the corresponding convex airbag 7, so that the motion target in the virtual motion scene maintains a straight line. The patient immerses themselves in the virtual motion scene and interacts with the corresponding convex airbag 7 through the visuals in the virtual motion scene. During the interaction, the patient actively adjusts their back muscle tension to maintain the straight line movement of the motion target, thereby training the patient's control over back muscle tension. This allows the patient to actively adjust their back muscle tension, achieving the effect of adjusting spinal posture, making the physiotherapy process more relaxed, and helping the patient eliminate tension and relax their back muscles.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the design of this case. All equivalent changes made based on the key design features of this case shall fall within the protection scope of this case.
