Description

Technical Field

[0001] This invention belongs to the field of medical assistive devices technology, specifically an assistive device for Parkinson's disease patients. Background Technology

[0002] Parkinson's disease is a common neurodegenerative disease. Common patient characteristics include resting tremor, bradykinesia, and postural and gait disturbances. For postoperative rehabilitation activities, relevant targeted activity assistive devices are usually required.

[0003] When patients perform head and neck extension training and leg knee extension training, these two activities are conducted separately. In order to shorten the cycle of assisted activity training for patients, separate activity training leads to poor efficiency. At the same time, when performing head and leg training, due to the postural reflex disorders of Parkinson's disease patients, it is necessary to ensure the uprightness of the upper body during the activity training, which requires the assistance of medical staff. In summary, separate head and leg movements reduce training efficiency and require additional personnel assistance, which consumes a lot of manpower. Therefore, we propose an activity assistive device for Parkinson's disease patients that allows patients to perform head, neck, and leg movement training simultaneously without the need for additional medical staff assistance. Summary of the Invention

The bottom of the seat cushion is equipped with a first toothed plate and a second toothed plate. The first toothed plate and the second toothed plate are respectively engaged with a leg strap to fix the legs and a chest strap to keep the upper body upright. The abutment assembly includes a connecting rod that engages with the movable unit, the connecting rod also includes an abutment rod that meshes with the movable unit, and an abutment wheel that is hinged to the end of the rod away from the movable unit and is used to push the lower leg upward.

[0006] Preferably, both ends of the movable auxiliary chair on the side away from the movable unit are fixedly connected to a pulling member. The pulling component specifically includes an elastic band fixedly connected to the movable auxiliary chair. A retainer that fits around the toes is fixedly connected to the bottom end of the elastic band. When the abutment rod moves, the abutment wheel pushes the lower leg upward, and the retainer is pulled by the elastic band, causing the retainer to stretch the toes upward. The chest strap is connected to a wobbling component that is connected to the bearing of the movable auxiliary chair. The wobbling component specifically includes a gap gear that is connected to the chest strap, a movable plate that engages with the gap gear and is sleeved on the outer wall of the connecting unit, and a third spring telescopic tube that provides elastic support between the movable plate and the movable auxiliary chair. The movable plate is provided with teeth that mesh with the gap gear. When the gap gear rotates, the movable plate drives the connecting unit to move.

[0007] Preferably, the pressing component further includes a first spring telescopic tube that provides elastic support between the seat cushion and the movable auxiliary chair, and the top surface of the seat cushion is made of rubber material.

[0008] Preferably, the movable unit includes a gear shaft connected to the bearing of the movable auxiliary chair, and the middle end of the outer wall of the gear shaft is wound around the connecting unit. Both ends of the gear shaft are engaged with the abutment rod and are fixedly connected with a pull rod.

[0009] Preferably, the linkage further includes a second spring telescopic tube that provides elastic support between the abutment rod and the movable auxiliary chair, the abutment rod being Z-shaped. The outer wall of the abutment wheel is provided with several protrusions for pushing against the calf.

[0010] Preferably, the connecting unit includes a connecting rope wound around the gear shaft, and an elastic adhesive tape is fixed to the top of the connecting rope. The elastic adhesive tape is semi-circular and is connected by an adhesive method.

[0011] Preferably, the leg strap includes a connecting shaft connected to the bearing of the movable auxiliary chair, the outer wall of the connecting shaft is wound with a first pull strap that engages with the movable auxiliary chair, and the end of the connecting shaft away from the first pull strap is engaged with the seat cushion.

[0012] Preferably, the chest strap includes a second pull strap that engages with the movable auxiliary chair, one end of the second pull strap is wound with a roller shaft connected to the bearing of the movable auxiliary chair, and a helical gear is fixedly connected to the end of the roller shaft away from the second pull strap. The outer wall of the helical gear is meshed with a drive rod that is connected to the bearing of the movable auxiliary chair.

[0013] Preferably, the end of the drive rod that meshes with the second toothed plate is provided with a gear connected to the bearing of the movable auxiliary chair, and the end of the drive rod away from the gear is fixedly connected with a first helical gear that engages with the helical gear.

[0014] Preferably, the card sleeve includes a C-shaped pouch fixed to the elastic band, and the C-shaped pouch is designed to be perforated. Both ends of the opening of the C-shaped bag are equipped with a first spring.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention achieves simultaneous training of the patient's head, neck, and legs by combining structures such as the contact component and the connecting unit. Pulling the lever drives the contact rod through the gear shaft, which gradually pushes the patient's lower leg area upward through the contact wheel, performing a knee extension exercise. The bottom end of the connecting rope is wound on the outer wall of the gear shaft, causing the elastic adhesive band to pull the patient's head backward. The reciprocating motion of the lever continuously performs seated knee extension exercises for the head, neck, and legs, thereby achieving the goal of simultaneously training the patient's head, neck, and legs. This invention, through the coordinated use of leg straps and chest straps, ensures the uprightness of the upper body and the stability of the legs during patient activity training, eliminating the need for additional medical assistance. The seat cushion, via the first and second toothed plates, causes the connecting shaft and drive rod to rotate. The bottom end of the first pull strap is wound around the surface of the connecting shaft, causing it to tighten and thus pull and limit the movement of the Parkinson's patient's legs. The drive rod, through helical gears, causes the roller to gradually pull the second pull strap, bringing the patient's chest area into contact with the backrest area of ​​the activity support chair, thereby ensuring the uprightness of the upper body without the need for additional medical assistance. This invention enhances the activity training effect for Parkinson's disease patients by incorporating structures such as elastic bands and ferrules. As the contact wheel gradually pushes the patient's lower leg upward, the elastic band tightens due to the upward movement of the lower leg, thereby driving the C-shaped ferrule to pull the patient's toes backward, promoting the foot activity training effect. When the roller rotates, it drives the intermittent gear to rotate synchronously, and the moving plate reciprocates to move the connecting rope, causing a slight swaying motion to the patient's head during the exercise, thus significantly improving the exercise effect on the patient's head and neck.

Implementation

[0018] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 11As shown, the present invention provides an assistive device for Parkinson's disease patients, including an assistive chair 100, and further comprising: Pressing component 200 is installed inside the movable auxiliary chair 100; The movable unit 300 is connected to the end bearing of the movable auxiliary chair 100 and is engaged with the abutment component 400 which is slidably connected to the movable auxiliary chair 100. The connecting unit 600 is movably connected to the side of the movable auxiliary chair 100 away from the movable unit 300, and its bottom end is wrapped around the movable unit 300. The pressing component 200 includes a seat cushion 201 that is movably connected to the movable auxiliary chair 100. The bottom of the seat cushion 201 is equipped with a first toothed plate 203 and a second toothed plate 204. The first toothed plate 203 and the second toothed plate 204 are respectively engaged with a leg strap 700 for fixing the legs and a chest strap 800 for keeping the upper body upright. The abutment assembly 400 includes a link 401 that engages with the movable unit 300. The link 401 also includes an abutment rod 4011 that engages with the movable unit 300, and an abutment wheel 402 that is hinged to the end of the link 401 away from the movable unit 300 and is used to push the lower leg upward.

[0020] like Figure 1 , Figure 2 As shown, both ends of the movable auxiliary chair 100 on the side away from the movable unit 300 are fixedly connected to pull members 500. The pulling component 500 specifically includes an elastic band 501 fixedly connected to the movable auxiliary chair 100. The bottom end of the elastic band 501 is fixedly connected to a retainer 502 that fits around the toes. When the abutment rod 4011 moves, the abutment wheel 402 pushes the lower leg upward, and the retainer 502 is pulled by the elastic band 501, causing the retainer 502 to stretch the toes. The chest strap 800 is connected to a wobbling component 900 that is connected to the bearing of the movable auxiliary chair 100. The wobbling component 900 specifically includes a gap gear 902 that is connected to the chest strap 800, and a movable plate 901 that is engaged with the gap gear 902 and sleeved on the outer wall of the connecting unit 600. A third spring telescopic tube 903 provides elastic support between the movable plate 901 and the movable auxiliary chair 100. The movable plate 901 is provided with teeth that mesh with the gap gear 902. When the gap gear 902 rotates, the movable plate 901 drives the connecting unit 600 to move. The roller 802 is connected to the gap gear 902 through a transmission belt, causing it to rotate, and the connecting rope 602 reciprocates through the third spring telescopic tube 903.

[0021] The above scheme is adopted: According to Figure 6It is known that the elastic band 501 has a rectangular groove in the middle. When the sleeve 502 is put on the patient's toes and is pulled by the elastic band 501, the rectangular groove will cause the elastic band 501 to be pulled into two sections and locked on both sides of the patient's leg, thereby improving the stability of pulling the patient's toes.

[0022] like Figure 1 , Figure 2 As shown, the pressing component 200 also includes a first spring telescopic tube 202 that provides elastic support between the seat cushion 201 and the movable auxiliary chair 100. The top surface of the seat cushion 201 is made of rubber material.

[0023] Using the above scheme: In the initial state, the seat cushion 201 is pushed upward inside the active assist chair 100. The Parkinson's patient sits down and presses the first spring telescopic tube 202 to gradually move to the bottom of the inner cavity of the active assist chair 100. The first toothed plate 203 and the second toothed plate 204 cause the connecting shaft 702 and the drive rod 804 to rotate synchronously, thereby fixing the patient's legs and keeping the patient's upper body upright, thus ensuring the stability of the patient's subsequent activity training.

[0024] like Figure 1 , Figure 10 As shown, the movable unit 300 includes a gear shaft 301 connected to the bearing of the movable auxiliary chair 100. The middle end of the outer wall of the gear shaft 301 is wound around the connecting unit 600. Both ends of the gear shaft 301 are engaged with the abutment rod 4011 and are fixedly connected with the pull rod 302.

[0025] Using the above method: Parkinson's disease patients sit on the activity assistive chair 100 and pull the lever 302 backward, which drives the abutment lever 4011 and abutment wheel 402 through the gear shaft 301 to push towards the patient's legs, making them rise and perform knee extension movements. By repeatedly pulling the lever 302, the patient uses the strength of their arms to drive the head, legs, and feet to perform corresponding activities and exercises, which also exercises the patient's hand movements.

[0026] like Figure 1 , Figure 8 As shown, the connecting rod 401 also includes a second spring telescopic tube 4012 that provides elastic support between the abutment rod 4011 and the movable auxiliary chair 100. The abutment rod 4011 is Z-shaped. The outer wall of the abutment wheel 402 is provided with several protrusions for pushing against the calf muscles.

[0027] Using the above scheme: the abutment rod 4011 will be driven by the rotation of the gear shaft 301 to move the abutment wheel 402 toward the calf of the Parkinson's patient. The abutment rod 4011 will push the calf upward to perform a seated knee extension exercise. During the exercise, the protrusions on the outer wall of the abutment wheel 402 will continuously press on the calf, providing massage assistance and thus improving the exercise training effect.

[0028] like Figure 1 , Figure 10 As shown, the connecting unit 600 includes a connecting rope 602 wound around the gear shaft 301. An elastic adhesive tape 601 is fixed to the top of the connecting rope 602. The elastic adhesive tape 601 is semi-circular and is connected by an adhesive method.

[0029] Using the above method: Parkinson's disease patients sit on the activity assistive chair 100, and the elastic adhesive tape 601 is put on their heads and the opening is glued. When the gear shaft 301 rotates, the bottom end of the connecting rope 602 will be wound around the outer wall of the gear shaft 301. At the same time, it will pull the elastic adhesive tape 601 to make the Parkinson's disease patient's head tilt backward, so as to exercise the head and neck.

[0030] like Figure 2 , Figure 3 , Figure 8 As shown, the leg strap 700 includes a connecting shaft 702 connected to the bearing of the movable auxiliary chair 100. The outer wall of the connecting shaft 702 is wound with a first pull strap 701 that engages with the movable auxiliary chair 100. The end of the connecting shaft 702 away from the first pull strap 701 is engaged with the seat cushion 201.

[0031] Using the above scheme: when the seat cushion 201 moves the first toothed plate 203 downward, the connecting shaft 702 rotates and drives the bottom end of the first pull strap 701 to wrap around its surface. The first pull strap 701 and the movable auxiliary chair 100 are connected by a buckle. When the bottom end of the first pull strap 701 is wrapped around the surface of the connecting shaft 702, the inner wall of the first pull strap 701 will be gradually tightened, thereby limiting the legs of the Parkinson's patient placed inside and keeping them stable, thus facilitating the subsequent use of the Parkinson's patient for activity training.

[0032] like Figure 2 , Figure 4 , Figure 10 As shown, the chest strap 800 includes a second pull strap 801 that engages with the movable auxiliary chair 100. One end of the second pull strap 801 is wound with a roller 802 that is connected to a bearing of the movable auxiliary chair 100. The end of the roller 802 away from the second pull strap 801 is fixedly connected to a helical gear 803. The outer wall of the helical gear 803 is meshed with a drive rod 804 that is connected to the bearing of the movable auxiliary chair 100.

[0033] Using the above scheme: the second toothed plate 204 moves down, causing the drive rod 804 to rotate, which in turn drives the roller 802 through the helical gear 803 to gradually pull the second pull belt 801, so that the upper body of the Parkinson's patient moves backward, thereby maintaining the uprightness of the upper body.

[0034] like Figure 4 As shown, one end of the drive rod 804 that meshes with the second toothed plate 204 is provided with a gear that is connected to the bearing of the movable auxiliary chair 100, and the other end of the drive rod 804 away from the gear is fixedly connected with a first helical gear that engages with the helical gear 803.

[0035] The above scheme is adopted: the second toothed plate 204 moves down and is driven to rotate by the gear of the drive rod 804, and drives the helical gear 803 to rotate through the first helical gear, thereby facilitating the subsequent pulling of the second pull belt 801.

[0036] like Figure 1 , Figure 7 As shown, the card sleeve 502 includes a C-shaped pocket 5021 fixedly connected to the elastic band 501, and the C-shaped pocket 5021 is designed to be hollow. Both ends of the opening of the C-type bag 5021 are equipped with a first spring 5022.

[0037] Using the above method: Parkinson's disease patients put their toes inside the C-shaped bag 5021, and the first spring 5022 pulls the opening of the C-shaped bag 5021 with elastic force at both ends to make it fit the toes of the Parkinson's disease patients and limit it, so as to ensure that the toes will not fall out of the C-shaped bag 5021 during subsequent leg activity training.

[0038] Working principle and usage process of this invention: During use, a Parkinson's patient sits on the cushion 201. The cushion 201 causes the connecting shaft 702 and the drive rod 804 to rotate via the first toothed plate 203 and the second toothed plate 204, respectively. At the same time, the bottom end of the first pull strap 701 will be wound around the surface of the connecting shaft 702, and the first pull strap 701 will be tightened to pull the legs of the Parkinson's patient to ensure their stability. Simultaneously, the drive rod 804, through the helical gear 803, causes the roller 802 to gradually pull the second strap 801, bringing the patient's chest area into contact with the backrest area of ​​the mobile auxiliary chair 100, thus ensuring the uprightness of the upper body; (when the patient sits on the seat cushion 201, external devices prevent the seat cushion 201 from shifting downwards. After the upper body and legs are connected by the first strap 701 and the second strap 801, the restriction on the seat cushion 201 is released. Under the action of gravity, the seat cushion 201 moves downwards, and the first strap 701 and the second strap 801 simultaneously tighten and fix it). When the patient is sitting on the cushion 201, the elastic adhesive band 601 is placed over the head and the toes are placed inside the C-shaped sleeve 5021. Then, the patient pulls the lever 302 with both hands, which drives the abutment lever 4011 to move towards the leg area through the gear shaft 301. The abutment wheel 402 will gradually push the patient's lower leg area upward to perform a knee extension movement. As the leg is raised, the elastic band 501 will be pulled due to the upward movement of the lower leg, which in turn drives the C-shaped sleeve 5021 to pull the patient's toes backward. Subsequently, when the gear shaft 301 moves, the bottom end of the connecting rope 602 will coil on its surface, and its top end will pull the patient's head backward through the elastic adhesive band 601. Through the continuous pulling and resetting of the lever 302, the head, neck, and legs will continuously perform seated knee extension exercises. In addition, the elastic band 501 and the C-shaped bag 5021 will repeatedly pull the toes, thereby improving the activity training effect on the patient. The patient's reciprocating pulling of the lever 302 will also exercise the muscles in their arms. At the same time, when the roller 802 rotates, it drives the gap gear 902 to rotate, which causes the moving plate 901 to pull the connecting rope 602 back and forth, thereby causing a slight shaking of the patient's head during exercise.
