Description

Technical Field

[0001] This invention belongs to the field of medical equipment technology, specifically an intelligent medical rehabilitation and fitness device for rehabilitation departments. Background Technology

[0002] After leg surgery, patients are prone to muscle atrophy, which can affect leg function. In order to help patients better reintegrate into society, in addition to drug treatment, rehabilitation and fitness training is also needed, such as resisted knee extension training. Current technology often uses isokinetic resistance equipment to perform resisted knee extension training for patients.

[0003] Because leg muscles often need to be massaged and relaxed after training to prevent lactic acid buildup, this device has a single function in actual use. After training, other devices are often needed to massage and relax the patient's leg muscles. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent medical rehabilitation and fitness device for rehabilitation departments, which can, to a certain extent, solve the problem that existing technologies have limited functionality and often require the use of other devices to massage and relax the patient's leg muscles after training.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: An intelligent medical rehabilitation and fitness device for rehabilitation departments includes a fixing plate, on which a thigh fixing component and a calf rehabilitation component are provided on any side wall of the fixing plate. The thigh fixing component is used to fix and massage the user's thigh, and the calf rehabilitation component is used to provide resistance to the patient's calf.

[0006] It also includes a control system, which controls the operation of the thigh fixation component and the calf rehabilitation component based on the patient's muscle condition.

[0007] Furthermore, the leg rehabilitation component includes a movable plate, a sliding groove fixedly connected to the side wall of the fixed plate, the fixed plate and the sliding groove slidingly engaged, an electromagnet fixedly connected to the inner side wall of the sliding groove, magnetic strips fixedly connected to the two side walls of the movable groove near the electromagnet, two clamping wheels symmetrically arranged on the side wall of the movable plate away from the sliding groove, and the electromagnet electrically connected to the control system.

[0008] Furthermore, the calf rehabilitation component also includes slide rails corresponding to the clamping wheels. The slide rails are all fixedly connected to the adjacent clamping wheels and are all electrically connected to the control system.

[0009] Furthermore, the thigh fixation assembly includes two symmetrically arranged mounting boxes, and the outer walls of the mounting boxes are fixedly connected to the fixing plate. Each mounting box is equipped with a first drive motor, and the output end of the first drive motor is coaxially fixedly connected to a lead screw. Each mounting box has a strip hole on its top or bottom wall near the other mounting box. A cylinder is fixedly connected to one nut seat, and a connecting rod is fixedly connected to the other nut seat. The connecting rod and the cylinder extend to the outside of the mounting box through the strip hole, and a fixed wheel is fixedly connected to the end of the connecting rod away from the nut seat and the output end of the cylinder. The first drive motor and the cylinder are electrically connected to the control system.

[0010] Furthermore, the control system includes a controller and several pressure sensors; the pressure sensors are used to collect pressure information applied by the patient to the fixed wheels; the controller is used to control the operation of the thigh fixation component and the calf rehabilitation component based on the pressure information.

[0011] Furthermore, it also includes several pulse massage patches that can be detachably connected to the patient's legs, and the controller controls the operation of the pulse massage patches based on pressure information.

[0012] Furthermore, the calf rehabilitation component also includes a drive box, which is located above the sliding groove and has an opening in its bottom wall. The drive box contains a second drive motor, and the output end of the second drive motor is coaxially and fixedly connected to a rotating rod. Several pull ropes are fixedly connected to the side wall of the rotating rod, and the pull ropes extend to the outside of the drive box through the opening. The end of the pull rope away from the rotating rod is fixedly connected to the top wall of the moving plate. The controller controls the second drive motor to work according to the pressure information.

[0013] Furthermore, the cylinder is fixedly connected to the bottom wall of the upper nut seat among the two nut seats.

[0014] The above scheme achieves the following principles and beneficial effects: When using this device, after the patient sits down, they place their legs between the two fixed wheels and the two clamping wheels in sequence. The device is then activated. Based on the pressure information collected by the pressure sensor, the controller controls the cylinder to extend, clamping the patient's thigh. Subsequently, the electromagnet is activated to provide resistance for the patient's knee extension movement. The device judges the patient's muscle state based on changes in the pressure applied to the fixed wheels. When the pressure applied to the fixed wheels increases, the patient's muscles harden due to contraction; when the pressure decreases, the patient's muscles relax and soften. Then, based on the patient's muscle state, the current flowing through the electromagnet is controlled to change the magnetic force between the electromagnet and the magnetic strip, thereby adjusting the resistance applied to the patient's leg and assisting the patient in resisted knee extension movements. After the rehabilitation exercise is completed, the device... The controller operates the first drive motor, which in turn rotates the lead screw to move the fixed wheel, massaging the patient's thigh. It also controls the slide rail to move the clamping wheel left and right alternately, massaging and relaxing the patient's calf. Through the design of the thigh fixation component, calf rehabilitation component, and control system, this device can adjust the resistance based on the patient's muscle exertion, avoiding muscle damage from excessive resistance and poor training results from insufficient resistance. Furthermore, the thigh fixation component and calf rehabilitation component can provide timely massage and relaxation after rehabilitation exercises, reducing muscle soreness. This addresses the limitations of existing technologies that often require additional equipment for muscle massage and relaxation after training, as they are often limited in function.

[0020] Example 1

[0021] The basic implementation examples are as follows: Figure 1-3 As shown:

[0022] An intelligent medical rehabilitation and fitness device for rehabilitation departments includes a fixing plate 1. A thigh fixation component 3 and a calf rehabilitation component 2 are provided on either side wall of the fixing plate 1. The thigh fixation component 3 is used to fix and massage the user's thigh. The thigh fixation component 3 includes two symmetrically arranged mounting boxes 31, with the outer walls of the mounting boxes 31 welded and fixed to the fixing plate 1. A first drive motor 35 is bolted to the inner wall of each mounting box 31. The preferred model of the first drive motor 35 is CC-M3H040-NN14. A lead screw 32 is coaxially welded to the output end of each first drive motor 35. A slotted hole is opened on the top or bottom wall of each mounting box 31 near the other mounting box 31. A cylinder 33 is bolted to any nut seat 321. The preferred model is CDJ2B10-15-B. A connecting rod 36 is welded and fixed on another nut seat 321. The connecting rod 36 and the cylinder 33 both extend to the outside of the mounting box 31 through the strip hole. The end of the connecting rod 36 away from the nut seat 321 and the output end of the cylinder 33 are both fixedly connected to the fixed wheel 34 by bolts. The calf rehabilitation component 2 is used to provide resistance to the patient's calf. The calf rehabilitation component 2 includes a moving plate 23. A sliding groove 21 is welded and fixed on the side wall of the fixed plate 1. The fixed plate 1 and the sliding groove 21 slide together. An electromagnet 22 is fixedly connected to the inner side wall of the sliding groove 21 by bolts. Magnet strips are fixedly connected to the two side walls of the moving groove near the electromagnet 22 by bolts. Two clamping wheels 25 are symmetrically arranged on the side wall of the moving plate 23 away from the sliding groove 21.

[0023] It also includes a control system, which is used to control the operation of the thigh fixation component 3 and the calf rehabilitation component 2 according to the patient's muscle state. The control system includes a controller and several pressure sensors. The controller is preferably a 2080Micro850, and the pressure sensor signal is preferably AST2000. The pressure sensors are all fixedly connected to the fixed wheel 34 by bolts. The controller is fixedly connected to the side wall of the fixed plate 1 by bolts. The output end of the pressure sensor is electrically connected to the input end of the controller. The input ends of the first drive motor 35, cylinder 33 and electromagnet 22 are all electrically connected to the output end of the controller.

[0024] In this embodiment, the calf rehabilitation component 2 also includes a slide rail 24 corresponding to the clamping wheel 25. The slide rail 24 is preferably of model WGWK-14H. The slide rail 24 is fixedly connected to the adjacent clamping wheel 25 by bolts. The input end of the slide rail 24 is electrically connected to the output end of the controller.

[0025] In this embodiment, a number of pulse massage patches that are detachably connected to the patient's legs are also included. The input ends of the pulse massage patches are all electrically connected to the output ends of the controller.

[0026] In this embodiment, the calf rehabilitation component 2 also includes a drive box 26. The drive box 26 is disposed above the sliding groove 21, and the outer wall of the drive box 26 is welded and fixed to the side wall of the fixing plate 1. The bottom wall of the drive box 26 has an opening. The drive box 26 is equipped with a second drive motor 27. The model of the second drive motor 27 is preferably CC-M3H040-NN14. The output end of the second drive motor 27 is coaxially welded and fixed with a rotating rod. Several pull ropes 272 are glued and fixed to the side wall of the rotating rod. All pull ropes 272 extend to the outside of the drive box 26 through the opening. The end of the pull rope 272 away from the rotating rod is glued and fixed to the top wall of the moving plate 23. The input end of the second drive motor 27 is electrically connected to the output end of the controller.

[0027] In this embodiment, the cylinder 33 is fixedly connected to the bottom wall of the upper nut seat 321 of the two nut seats 321 by bolts.

[0028] The specific implementation process is as follows: When using this device, after the patient sits down, he places his legs between the two fixed wheels 34 and the two clamping wheels 25 in sequence. Then, the device is started, the cylinder 33 extends, and drives the fixed wheels 34 to move downward, so that the upper fixed wheel 34 contacts the patient's thigh. The pressure sensor continuously collects the pressure information applied by the patient to the fixed wheels 34. When the pressure information reaches the set value, both fixed wheels 34 are in close contact with the patient's thigh. The controller stops the cylinder 33 from working, and the clamping of the patient is completed. Then, the controller controls the electromagnet 22 to work. At this time, the patient performs knee extension movement. The electromagnet 22 generates magnetic force, which prevents the patient from sliding the moving plate 23, thereby giving the patient resistance and helping the patient to perform resistance exercises.

[0029] Simultaneously, during knee extension, the patient's rectus femoris and other muscles contract and tighten, accompanied by a slight bulge, which increases the pressure exerted by the patient on the fixed wheel 34. By monitoring the pressure information exerted by the patient on the fixed wheel 34 during the exercise, the force exerted by the patient's leg can be monitored. When the pressure information exceeds the set maximum value, the patient's muscles are too tight during the exercise, that is, the resistance is too great, which can easily lead to muscle fatigue or even injury. At this time, the controller reduces the current passing through the electromagnet 22, reducing the magnetic force of the electromagnet 22, thereby reducing the resistance exerted by the device on the patient's leg. When the pressure information is lower than the set minimum value, the resistance is too small, causing the patient's muscles to be too relaxed, making it difficult to achieve the training purpose. At this time, the controller increases the current passing through the electromagnet 22, increasing the resistance exerted by the electromagnet 22 on the patient's leg.

[0030] When the controller increases the current through the electromagnet 22, it continues to increase to a certain value, but the pressure information does not change. This may be because the patient's muscle recovery is not good and it is difficult for the patient to contract on their own for training. At this time, the controller controls the pulse massage patch to work, releasing low-pressure pulses to stimulate the patient's muscles. At the same time, the controller cuts off the current to the electromagnet 22 and controls the second drive motor 27 to work. The second drive motor 27 drives the rotating rod to rotate, so that the pull rope 272 is wrapped around the rotating rod, pulling the moving plate 23 to move upward, thereby assisting the patient to lift the lower leg. Then the second drive motor 27 drives the rotating rod to move in the opposite direction, releasing the pull rope 272 wrapped around the rotating rod. Under the action of gravity, the moving plate 23 moves downward, assisting the patient to lower the lower leg.

[0031] After the rehabilitation exercise is completed, the controller controls the first drive motor 35 to work. The first drive motor 35 drives the lead screw 32 to rotate, thereby driving the two fixed wheels 34 to move left and right, providing a certain massage and relaxation to the patient's thigh. At the same time, the controller controls the slide rail 24 to move, driving the clamping wheel 25 to move left and right alternately, providing a certain massage and relaxation to the patient's calf.

[0032] The cylinder 33 mounted on the upper nut seat 321 in this device is less likely to cause the patient's leg to move upwards during its movement compared to a cylinder 33 mounted on the lower nut seat 321, thus preventing the patient's thigh from tilting and causing discomfort. Through the thigh fixation component 3, the calf rehabilitation component 2, and the control system, this device can adjust the resistance based on the patient's leg according to their muscle exertion state. This avoids muscle damage caused by excessive resistance and poor training results due to insufficient resistance. Simultaneously, the thigh fixation component 3 and the calf rehabilitation component 2 can provide timely massage and relaxation to the patient's leg after rehabilitation exercises, reducing muscle soreness. Furthermore, the device, with its pulse massage patches and second drive motor 27, can assist patients with poor muscle recovery by providing power and stimulating muscle contraction, thus enabling its application in a wider range of scenarios.
