Description

Technical Field

[0001] This invention relates to the field of training device technology, specifically to a rehabilitation and assistive training device for hemiplegic patients. Background Technology

[0002] Hemiplegic patients often experience unilateral lower limb muscle weakness, motor control impairment, and limited joint movement due to central nervous system damage. Clinical rehabilitation guidelines clearly state that after the flaccid paralysis stage, "leg-lifting resistance training" must be introduced as early as possible—that is, applying controllable resistance to the hip flexor muscles to activate residual motor units, promote neuromuscular pathway reconstruction, and lay the foundation for subsequent sitting, standing, and walking. However, currently widely used rehabilitation assistive training beds mainly focus on passive knee and ankle flexion and extension or simple spring assistance in the horizontal direction of the bed surface, completely lacking the crucial "leg-lifting resistance" component. Patients cannot complete hip flexion movements against adjustable resistance in a safe supine position, leading to continuous atrophy of hip flexion strength, aggravation of joint contractures, and consequently affecting the recovery of the entire gait cycle, delaying the rehabilitation process, and increasing the risk of secondary complications. Therefore, there is a need for a device that can achieve precise, progressive, and controllable leg-lifting resistance training in a bedridden state to fill a critical gap in early rehabilitation for hemiplegic patients. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a rehabilitation and assistive training device for hemiplegic patients, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a rehabilitation and assistive training device for hemiplegic patients, comprising a bed frame, a mattress placed on the surface of the bed frame, multiple mattresses being provided, a flexion-extension training component provided at one end of the bed frame for knee flexion-extension training, lifting mechanisms provided on both sides of the bed frame, the lifting mechanisms being connected to a damping mechanism, the damping mechanism providing resistance to the lifting mechanisms, the lifting mechanisms cooperating with the damping mechanisms for resistance training, support legs provided on both sides of the bed frame, one side of the support leg being fixedly connected to the damping mechanism, and a support component provided at the other end of the bed frame for supporting the user's shoulders.

[0005] Preferably, the flexion-extension training component includes a support plate located inside a groove at one end of the bed. A top cover is installed on the top of the groove at one end of the bed, and the surface of the top cover has two strip-shaped slots. The bottom end of the support plate is rotatably connected to the top end of the slide plate. Two downward protruding structures are provided on one side of the support plate to limit the rotation angle of the support plate. The two ends of the slide plate are slidably connected to the slide rod, and the two ends of the slide rod are connected to the bed. A first spring is fitted on the outside of the slide rod. This flexion-extension training component achieves supine knee flexion resistance through spring-slide rod linkage, which not only limits the safe rotation angle but also allows real-time observation of foot alignment through the strip-shaped slots in the top cover, completing angle protection, resistance loading, and movement monitoring in one go.

[0006] Preferably, the other end of the slide rod is slidably connected to the adjustment plate, one side of the adjustment plate is in contact with the first spring, the adjustment plate is rotatably connected to one end of the first threaded rod, and the first threaded rod is threadedly connected to one end of the bed; rotating the first threaded rod can steplessly move the adjustment plate, compressing or releasing the first spring in real time, thereby achieving precise, gradual, and personalized adjustment of the knee flexion resistance in the supine position.

[0007] Preferably, the lifting mechanism includes a lifting plate with grooves on both sides and steel balls inside the grooves. Both ends of the lifting plate are slidably connected to a sliding groove, which is fixedly connected to the bed frame. A roller is located at the bottom of one of the sliding grooves. A connecting arm is connected to one end of the top of the lifting plate, and one end of the connecting arm is connected to a support rod. One side of the lifting plate is slidably connected to a pin. The pin has an annular protrusion on its exterior, and a second spring is fitted around it. The pin is inserted into a positioning hole via a rotating arm. The positioning hole is located on one side of the rotating arm. The steel ball-sliding groove combination and the bottom roller ensure near-zero friction when lifting the lifting plate. The pin-second spring-positioning hole lock is secured with a single button, instantly fixing the support rod angle and quickly resetting it, achieving a smooth, safe, and efficient operation.

[0008] Preferably, the damping mechanism includes a damping groove, inside which a first piston block is disposed. The first piston block is fitted onto one end of a piston rod, and the other end of the piston rod is connected to a telescopic block. The top side of the telescopic block is connected to a limiting rod, which is slidably connected to the damping groove. The telescopic block is connected to one end of a connecting cable, and the other end of the connecting cable is connected to the bottom of the lifting plate. A fixing block is fixedly installed inside the damping groove. A second piston block is disposed on one side of the fixing block. The second piston block is fixedly installed outside the piston rod and is slidably connected to the inside of the damping groove. A third spring is disposed on one side of the second piston block. The dual-piston-oil-spring composite damping converts the upward displacement of the lifting plate into a controllable oil flow that is synchronously compressed with the third spring, providing a smooth, linear, and finely adjustable leg-lifting resistance in one go, achieving precise load control for supine hip flexion training.

[0009] Preferably, the surface of the fixing block is provided with a groove for liquid flow. An adjusting block is provided on one side of the fixing block. The adjusting block is threadedly connected to the outer wall of the damping groove. The shape of one end of the adjusting block matches the shape of the internal groove of the fixing block. A pressure piston is provided at one end of the damping groove. There is a cavity between the pressure piston and the end of the damping groove, and a sealing plug is provided on one side of the cavity. Twisting the adjusting block can change the effective flow area of ​​the groove of the fixing block, and steplessly fine-tune the oil resistance. With the pressure piston-sealing plug structure, the lifting resistance can be "one-click precise setting + long-term sealing and pressure maintenance", taking into account both personalization and durability.

[0010] Preferably, the support component includes an adjustment groove, which is installed on both sides of the bed. The surface of the adjustment groove has equally spaced holes and slots, and a plug is inserted into the adjustment groove. A rubber pad is glued to one side of the plug. The plug-hole array enables quick adjustment of the shoulder support position, and the rubber pad provides a soft fit and anti-slip limit at one time, taking into account the comfort and safety of patients of different heights.

[0011] This invention provides a rehabilitation and assistive training device for hemiplegic patients. It has the following beneficial effects: (1) In this kind of health care assistive training device for hemiplegia, the user lies on the mattress and adjusts the position of the plug and the rubber pad through the adjustment groove. The rubber pad can support the user's shoulders. Then the user steps on the support plate, which can drive the slide to slide and compress the first spring. When the user's foot bends, the first spring can release the stored force, so that the support plate and the slide can return to their original position. The resistance of the first spring can achieve the effect of flexion and extension training. By rotating the first threaded rod, the first threaded rod can drive the adjustment plate to move. While the adjustment plate moves, it can compress the first spring and adjust the pressure of the first spring, which is conducive to adjusting the pressure of the flexion and extension training component.

[0012] (2) This kind of rehabilitation and assistive training device for hemiplegic patients, by rotating the connecting arm, can drive the support rod to stand up. Then, under the action of the second spring, the pin can be inserted into the positioning hole, so that the angle of the connecting arm can be fixed. The user can lift his foot to drive the support rod to move upward. The support rod can drive the lifting plate to move upward. At the same time, the lifting plate can drive the telescopic block to move through the connecting cable. The telescopic block can drive the piston rod to move. The piston rod can drive the first piston block to move, so that the first piston block can squeeze the oil inside the damping groove. The oil inside the damping groove can enter the cavity at the other end of the damping groove through the hole groove inside the fixed block, thereby squeezing the third spring and compressing the third spring. Through the damping generated by the third spring and the fluid passing through the fixed block, the user can perform resistance training when lifting his foot, thus improving the functionality of the device.

Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example 1:

[0016] Please see Figure 1-6This invention provides a technical solution: a rehabilitation and assistive training device for hemiplegic patients, including a bed 1, a mattress 2 placed on the surface of the bed 1, multiple mattresses 2, a flexion and extension training component 3 at one end of the bed 1 for knee flexion and extension training, lifting mechanisms 4 on both sides of the bed 1 connected to damping mechanisms 5, the damping mechanisms 5 providing resistance to the lifting mechanisms 4, the lifting mechanisms 4 cooperating with the damping mechanisms 5 for resistance training, support legs 6 on both sides of the bed 1, one side of the support legs 6 fixedly connected to the damping mechanisms 5, and a support component 7 at the other end of the bed 1 for supporting the user's shoulders. This device integrates flexion and extension training with leg-lifting resistance training functions on the bed 1, enabling hemiplegic patients to complete controllable resistance training targeting the hip flexor muscle group while in bed. This effectively activates residual motor units, promotes neuromuscular pathway reconstruction, and prevents hip flexion strength atrophy and joint contractures. It fills the gap in the existing rehabilitation and rehabilitation assistive training beds that lack the key element of "leg-lifting resistance," and solves the problems of hindered gait cycle recovery, delayed rehabilitation process, and increased risk of secondary complications caused by the lack of early resistance training. Example 2:

[0017] Please see Figure 1-6 This invention provides a technical solution: the flexion and extension training component 3 includes a support plate 301, which is located inside a groove at one end of the bed 1.

The user then steps on the support plate 301, which causes the sliding plate 302 to slide, compressing the first spring 303. When the user bends their leg, the first spring 303 releases its stored force, allowing the support plate 301 and the sliding plate 302 to return to their original positions. The resistance of the first spring 303 provides a flexion-extension training effect. By rotating the first threaded rod 307, the adjustment plate 306 can be moved.
