Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] The stroke patient supine rehabilitation training device of the present invention, such as Figures 1 to 8 As shown, it includes a bracket 1, a crossbeam 2 is provided on the top of the bracket 1, and multiple modular interfaces 9 are provided on the crossbeam 2.

[0018] The support frame 1 supports the entire training device and includes bases at both ends. Suction cups 18 and clamps 19 are located at the bottom of the support frame 1. The suction cups 18 can be fixed to a smooth surface, improving the stability of the entire support frame 1 and preventing it from moving during training. The clamps 19 can be secured to the edge of a hospital bed or convalescent bed using locking screws, thus fixing the entire training device to the edge of the bed, with the crossbeam 2 positioned above the bed for easy rehabilitation training. The support frame 1 has a pair of vertical lifting columns 8, with both ends of the crossbeam 2 mounted on the lifting columns 8. The crossbeam 2 is a telescopic beam. Existing electric telescopic structures can be used for the lifting columns 8 and the telescopic beam, allowing adjustment of the height and length of the crossbeam 2 to accommodate various sizes of hospital beds and convalescent beds.

[0019] One structure of beam 2 is as follows Figure 2 As shown, the present invention also includes a four-limb linkage bicycle 3, an upper limb suspension belt 4, a lower limb suspension belt 5, and a resistance band 6. The four-limb linkage bicycle 3, the upper limb suspension belt 4, the lower limb suspension belt 5, and the resistance band 6 are all connected to modular plugs 7, and each modular plug 7 is detachably connected to a modular interface 9.

[0020] The four-limb coordinated pedal bike 3 is used for four-limb coordinated training, the upper limb suspension strap 4 and lower limb suspension strap 5 are used for suspension training of the four limbs, and the resistance band 6 is used for muscle strength training, balance and core stability training, etc. By setting up multiple training components, a variety of training can be carried out to better meet training needs.

[0021] The main bodies of the four-limb coordinated pedal bike 3, upper limb suspension belt 4, lower limb suspension belt 5, and resistance band 6 all utilize existing technologies. Based on these existing technologies, the installation methods of each training component are improved. Specifically, each training component is detachably installed to the crossbeam 2 via a modular plug 7 and modular interface 9 with identical structures. During training, only one or two training components can be installed, while the others are removed, avoiding interference from multiple components. When a different training method is needed, the corresponding training component is simply replaced. This convenient operation allows for multiple training methods while simplifying the structure of the training device. Furthermore, depending on the patient's body type, the required training components can be installed on the modular interface 9 in appropriate positions for convenient training.

[0022] As a possible implementation method, such as Figures 3 to 5As shown, the modular interface 9 is located on the side wall of the crossbeam 2. The shape and size of the modular interface 9 are adapted to the shape and size of the modular plug 7, ensuring that the modular plug 7 can be inserted into the modular interface 9. The side wall of the modular interface 9 has a pin mounting hole, in which a positioning pin 10 is installed. The positioning pin 10 is connected to the bottom of the pin mounting hole via a first spring 11. The positioning pin 10 is connected to a slider 12, which slides horizontally with the crossbeam 2. The side wall of the modular plug 7 has a pin hole 14 that matches the positioning pin 10.

[0023] Under normal conditions without external interference, the end of the positioning pin 10 extends into the modular interface 9. When installing the modular plug 7, slide the slider 12. The slider 12 drives the positioning pin 10 to fully enter the pin mounting hole, compressing the first spring 11. Then, insert the modular plug 7 into the modular interface 9. Next, release the slider 12, and the first spring 11 automatically returns to its original position, pushing the positioning pin 10 into the pin hole 14. At this time, the positioning pin 10 locks the modular plug 7. When it is necessary to remove the modular plug 7, slide the slider 12. The slider 12 drives the positioning pin 10 to move outside the pin hole 14, allowing the modular plug 7 to be removed. To ensure that the modular plug 7 quickly and stably enters the modular interface 9, magnetic blocks that attract each other can be installed on the inner wall of the modular interface 9 and the outer wall of the modular plug 7. After inserting the modular plug 7 into the modular interface 9, the magnetic blocks hold the modular plug 7 in place. At this time, the modular plug 7 can be released, and then the slider 12 can be operated to achieve one-handed installation of the modular plug 7.

[0024] During training, the force applied by the patient to the training components such as the four-limb linkage bicycle 3, upper limb suspension belt 4, lower limb suspension belt 5, and resistance band 6 is ultimately transmitted to the modular plug 7. To improve the stability of the modular plug 7 and prevent it from falling off under stress during training, the top and bottom walls of the modular interface 9 are provided with positioning holes 13, and the top and bottom walls of the modular plug 7 are respectively provided with upper guide holes and lower guide holes extending vertically to pin holes 14. An upper positioning post 1 is provided in the upper guide hole. 5. The upper positioning post 15 is slidably engaged with the upper guide hole, and the lower positioning post 16 is provided in the lower guide hole. The lower positioning post 16 is slidably engaged with the lower guide hole. Both the upper positioning post 15 and the lower positioning post 16 are connected to the modular plug 7 through the second spring 17. The top of the lower positioning post 16 is provided with a lower inclined surface, and the bottom of the upper positioning post 15 is provided with an upper inclined surface. The positioning pin 10 is inserted into the pin hole 14, and when the positioning pin 10 enters the pin hole 14, its end pushes the upper positioning post 15 and the lower positioning post 16 into the positioning hole 13 at the same time.

[0025] Under normal conditions without external interference, the upper positioning post 15 and the lower positioning post 16 are both located inside the modular plug 7. When the positioning pin 10 enters the pin hole 14, the upper inclined surface of the upper positioning post 15 and the lower inclined surface of the lower positioning post 16 contact the positioning pin 10. The positioning pin 10 continues to move, pushing the upper positioning post 15 upward and simultaneously pushing the lower positioning post 16 downward, so that the upper end of the upper positioning post 15 enters the positioning hole 13 on the top wall of the modular interface 9, and the lower end of the lower positioning post 16 enters the positioning hole 13 on the bottom wall of the modular interface 9, causing the second spring 17 to deform. At this time, the top, bottom, and side surfaces of the modular plug 7 are connected to the modular interface 9, and the force is distributed among the upper positioning post 15, the lower positioning post 16, and the positioning pin 10, resulting in higher stability. After the positioning pin 10 leaves the pin hole 14, the second spring 17 returns to its original position, pushing the upper positioning post 15 and the lower positioning post 16 back into the modular plug 7.

[0026] During training, the force applied by the patient should be appropriate to avoid excessive force that could lead to further limb injury. To facilitate flexible adjustment of training force according to the patient's individual condition and prevent overexertion, the upper limb suspension belt 4, lower limb suspension belt 5, and resistance belt 6 of this invention are all equipped with elastic adjustment mechanisms. Simultaneously, the four-limb linked bicycle 3 includes a frame 31 and resistance wheels 32. The resistance wheels 32 are rotatably mounted on the frame 31 and are connected to the resistance adjustment mechanism.

[0027] The band is generally made of a flexible material with appropriate elasticity. The elasticity adjustment mechanism can adjust the length of the band to adjust the elasticity. When the patient's range of motion remains unchanged during training, the longer the band is, the less force the patient exerts on the band, that is, the less elasticity. Therefore, the elasticity can be adjusted by adjusting the length of the band.

[0028] Specifically, such as Figure 6As shown, the elastic adjustment mechanism includes a housing 20, which can be directly connected to the modular plug 7 as a single unit, or connected to the modular plug 7 via a connecting rope or the like. A take-up shaft 21, rotatably connected to the housing 20, is disposed inside the housing 20. The upper end of the belt is wound around the take-up shaft 21, and the lower end of the belt extends out of the housing 20. The take-up shaft 21 is a circular shaft. When the take-up shaft 21 rotates, it can wind or unwind the belt, thereby adjusting the length of the belt outside the housing 20. To facilitate control of the rotation of the take-up shaft 21 and to ensure that the take-up shaft 21 remains fixed after adjustment and does not rotate automatically, the present invention provides a brake transmission gear 22 on the take-up shaft 21. A brake shaft 24 and a transmission shaft 25, parallel to the take-up shaft 21, are disposed above the take-up shaft 21. The brake shaft 24 and the transmission shaft 25 are coaxial. The brake shaft 24 is a circular shaft, and the transmission shaft 25 is a non-circular shaft, such as a square shaft. One end of the brake shaft 24 is rotatably engaged with one end of the transmission shaft 25, and the other end of the brake shaft 24 is slidably engaged with the housing 20. The other end of the transmission shaft 25 is both rotatably and slidably engaged with the housing 20. The transmission shaft 25 can rotate, while the brake shaft 24 cannot. When the transmission shaft 25 rotates, the brake shaft 24 remains fixed, and when the transmission shaft 25 moves axially, it can drive the brake shaft 24 to move axially synchronously. A brake gear 23 is provided on the brake shaft 24, and an adjusting gear 26 is provided on the transmission shaft 25. The brake transmission gear 22, brake gear 23, and adjusting gear 26 are all identical gears. One of the brake gear 23 and the adjusting gear 26 meshes with the brake transmission gear 22.

[0029] During normal training using the upper limb suspension belt 4, lower limb suspension belt 5, or resistance band 6, the brake gear 23 engages with the brake transmission gear 22. Since the brake shaft 24 cannot rotate, the brake gear 23 will not rotate. At this time, the brake transmission gear 22 and the winding shaft 21 will also not rotate, thus ensuring the belt length remains stable. When it is necessary to adjust the belt's elasticity, the brake shaft 24 is moved axially. The brake shaft 24 drives the transmission shaft 25 to move, causing the brake gear 23 and the adjusting gear 26 to move synchronously. This disengages the brake gear 23 from the brake transmission gear 22, and engages the adjusting gear 26 with the brake transmission gear 22. Because the brake shaft 24 cannot rotate, neither the brake gear 23 nor the adjusting gear 26 will rotate during the axial movement of the brake shaft 24, ensuring that the teeth of the adjusting gear 26 align with the tooth grooves of the brake transmission gear 22, allowing the adjusting gear 26 to precisely engage with the brake transmission gear 22. After the adjusting gear 26 meshes with the brake transmission gear 22, the transmission shaft 25 is rotated. The transmission shaft 25 drives the adjusting gear 26 to rotate, which in turn drives the brake transmission gear 22 and the take-up shaft 21 to rotate, realizing the unwinding and winding of the belt. After adjustment, the brake shaft 24 is moved again, causing the adjusting gear 26 to disengage from the brake transmission gear 22, and the brake gear 23 re-meets with the brake transmission gear 22, braking the take-up shaft 21. Since the brake transmission gear 22, the adjusting gear 26, and the brake gear 23 are identical, after the adjusting gear 26 rotates, the tooth profile of the brake gear 23 still aligns with the tooth groove of the brake transmission gear 22. When the brake gear 23 moves axially, it can accurately mesh with the brake transmission gear 22.

[0030] The resistance wheel 32 is connected to the foot pedal mechanism and the hand crank mechanism via a transmission belt, transmission chain, etc. The resistance adjustment mechanism can adjust the resistance when the resistance wheel 32 rotates, thereby adjusting the force the patient exerts when operating the foot pedal mechanism and the hand crank mechanism during training. Specifically, as shown... Figure 7As shown, the impedance wheel 32 is mounted on the mounting base 33 via the mounting shaft 34. The mounting base 33 is mounted on the frame 31. The resistance adjustment mechanism includes an adjustment seat 35, which is fixedly connected to the mounting base 33. An adjustment stud 36 is provided on the adjustment seat 35, and the adjustment stud 36 is threadedly engaged with the adjustment seat 35. The lower end of the adjustment stud 36 is connected to a brake pad 38 via a third spring 37. The side of the brake pad 38 away from the third spring 37 is a friction surface that mates with the circumferential surface of the impedance wheel 32. When the friction surface of the brake pad 38 contacts the circumferential surface of the impedance wheel 32, there is frictional resistance between them. When the required resistance of the impedance wheel 32 is 0, the brake pad 38 does not contact the impedance wheel 32. When frictional resistance is needed, rotating the adjusting stud 36 moves it downwards, pushing the third spring 37 and brake pad 38 downwards. When the brake pad 38 contacts the impedance wheel 32, it cannot move further, and the third spring 37 is compressed, gaining a certain elastic force. This elastic force is transmitted to the brake pad 38, which applies pressure to the impedance wheel 32. As the impedance wheel 32 rotates, frictional resistance exists between the impedance wheel 32 and the brake pad 38. To increase frictional resistance, rotating the adjusting stud 36 further compresses the third spring 37. To decrease pressure, rotating the adjusting stud 36 in the opposite direction moves it upwards, reducing the compression of the third spring 37, decreasing its elastic force, and lowering the frictional resistance between the brake pad 38 and the impedance wheel 32.

[0031] The adjusting seat 35 passes through the brake pad 38 and slides in cooperation with the brake pad 38, which can ensure that the brake pad 38 moves stably.

[0032] In addition to the aforementioned training methods such as limb coordination training, limb suspension training, muscle strength training, and balance and core stability training, lumbar and abdominal suspension training can also be performed, such as... Figure 8 As shown.

[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
