Description

Technical Field

[0001] This invention relates to the field of turning-over assistive devices, specifically a turning-over assistive device for stroke rehabilitation. Background Technology

[0002] Stroke, also known as cerebrovascular accident, is an acute cerebrovascular disease. It is a group of diseases caused by the sudden rupture of blood vessels in the brain or by blockage of blood vessels, which prevents blood from flowing into the brain and causes damage to brain tissue. It includes ischemic and hemorrhagic strokes.

[0003] The most common symptoms of stroke are sudden weakness in one side of the face, arm or leg, sudden collapse and loss of consciousness. Other symptoms include sudden numbness in one side of the face, arm or leg, or sudden facial drooping and hemiplegia. During stroke rehabilitation, patients are bedridden due to hemiplegia, so they need to use assistive devices to turn over.

[0004] Regarding a simple assisted turning device for internal medicine nursing with application number CN202110727769.3, through a transmission component, the patient lies on the upper surface of the first support seat and slides one side of the body onto the upper surface of the second support seat. As the second support seat moves downward, the deflection angle of the first support seat increases continuously, and the deflection angle of the patient's body also increases continuously. Then, the medical staff can push the patient to turn the patient over and place them face down on the other first support seat. After the turning is completed, the handle is rotated in the opposite direction to repeat the above actions, which causes the second support seat to move upward, so that the deflection angle of the two first support seats gradually decreases until they are in a parallel state, thus completing the turning of the patient.

[0005] Defects: In the process of assisting patients to turn over by flipping the support seat, this patent does not have a protective structure on the other side, and the patient cannot maintain a stable attachment to the support seat. As a result, medical staff need to provide auxiliary support to the patient on the other side to prevent the patient from falling off the support seat. Therefore, multiple medical staff are required to complete the patient's turning over, which wastes unnecessary medical resources.

[0006] Regarding the stroke patient turning assist device with application number CN202220752752.3, it is designed with a turning mechanism that causes a starting cylinder to drive a rotating plate to rotate and tilt, the rotating plate to drive a rotating shaft to move upward, the rotating shaft to drive a rotating block to rotate and tilt, the rotating plate to drive a U-shaped frame to move, the U-shaped frame to drive a T-shaped slider to slide in a T-shaped groove, the rotating plate to drive a cylinder to move, and the cylinder to drive the slider to slide in a C-shaped rail. It has the advantages of assisting patients to turn left and right and reducing the inconvenience of manual turning by medical staff.

[0007] Defects: Although this patent can assist patients in turning over and provide support by simultaneously driving two rotating blocks with two cylinders to flip them, the rotating blocks are a single plate. During the process of assisting patients in turning over and providing support, medical staff cannot perform rehabilitation massages or wipe their bodies. In addition, the requirement to drive two cylinders simultaneously for support results in higher production and usage costs. Summary of the Invention

[0008] To address the problems in the prior art, the present invention provides a turning assist device for stroke rehabilitation.

[0009] The technical solution adopted by the present invention to solve its technical problem is: a turning assist device for stroke rehabilitation, including a support plate, on both sides of the support plate are hinged to a flipping plate through a first rotating shaft, each flipping plate has a groove on the top of one end near the support plate, a driven assist plate is hinged to the inside of the groove through a second rotating shaft, and a horizontal plate is fixedly connected to both ends of the bottom of the support plate, and a fixing frame is connected to the side of the two horizontal plates that are far apart from each other.

[0010] The fixed frame has two third rotating shafts symmetrically connected inside. Gears are fixedly connected to the shaft walls of the two third rotating shafts, and the two gears are staggered. Transmission grooves are opened on the outer walls of the two gears. Transmission belts are sleeved inside the transmission grooves of the gears, and transmission wheels are connected to the gears through the transmission belts. The transmission wheels are fixedly sleeved on the shaft wall of the first rotating shaft.

[0011] Both ends of the bottom of the fixed frame are rotatably connected to the first rocker plate via the fourth rotating shaft. Both ends of the top of the first rocker plate are provided with sliding grooves. A fixed shaft is slidably connected inside each sliding groove. The tops of the two fixed shafts are respectively fixedly connected to the second rocker plate and the third rocker plate. The third rocker plate is located below the gear and is meshed with the adjacent gear. A push plate is fixedly connected to the top of the second rocker plate at the end away from the fixed shaft.

[0012] An arc rod is fixedly connected to the bottom of the driven auxiliary plate at the end away from the second rotating shaft. The inner bottom of the groove is provided with a matching arc groove corresponding to the arc rod. The end of the arc rod away from the driven auxiliary plate passes through the arc groove and contacts the push plate.

[0013] Specifically, a locking bolt is inserted into the side wall of the fixing frame away from the horizontal plate, and the locking bolt passes through one end of the fixing frame and is threadedly connected to the adjacent horizontal plate.

[0014] Specifically, the support plate and the flip plate have a first adapter groove and a second adapter groove respectively on the side wall near the first rotating shaft.

[0015] Specifically, the arc rod is coaxial with the second rotation axis.

[0016] Specifically, the end of the driven auxiliary plate away from the second rotation axis is arc-shaped.

[0017] Specifically, both ends of the bottom of the two horizontal plates are fixedly connected to support frames, and the length of the support frames is greater than the thickness of the fixed frames.

[0018] The beneficial effects of this invention are:

[0019] The present invention discloses a turning assist device for stroke rehabilitation, which supports a support plate and a flipping plate and a fixing frame hinged to both sides of the support plate by a horizontal plate. The flipping plate can flip around the support plate on both sides about a first rotation axis. When the flipping plate flips, it drives a first transmission wheel to rotate through the first rotation axis. When the first transmission wheel rotates, it drives a gear to rotate through a transmission belt. The gear drives a third rocker to move. When the third rocker moves, it causes a second rocker at the other end of the first rocker to move in the opposite direction, thereby pushing the arc rod through the push plate at the top of the second rocker. The driven auxiliary plate rotates upward around the second rotation axis. After rotation, the driven auxiliary plate can provide auxiliary support for the patient, effectively protecting the patient and preventing them from falling due to excessive turning. Furthermore, by setting a servo motor, the rotating plate and the driven auxiliary plate can be driven to rotate in opposite directions to provide auxiliary support for the patient. This can effectively reduce the cost of the turning assist device and save resources. In addition, while the driven auxiliary plate is providing auxiliary support for the patient, medical staff can use the gaps between the driven auxiliary plates to perform rehabilitation massage or wipe the patient's body.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1-8 As shown, the present invention provides a turning assist device for stroke rehabilitation, including a support plate 1. Both sides of the support plate 1 are hinged with a flipping plate 3 via a first rotating shaft 2. Each flipping plate 3 has a groove 4 at the top near the end of the support plate 1. A driven assist plate 6 is hinged inside the groove 4 via a second rotating shaft 5. Both ends of the bottom of the support plate 1 are fixedly connected with a horizontal plate 7. A fixing frame 9 is connected to the side of the two horizontal plates 7 that are far apart from each other.

[0032] The fixed frame 9 has two third rotating shafts 10 symmetrically connected inside. Gears 11 are fixedly connected to the shaft walls of the two third rotating shafts 10, and the two gears 11 are staggered. Transmission grooves 12 are opened on the outer walls of the two gears 11. Transmission belts 13 are sleeved inside the transmission grooves 12 of the gears 11, and the gears 11 are connected to transmission wheels 14 through the transmission belts 13. Transmission wheels 14 are fixedly sleeved on the shaft wall of the first rotating shaft 2.

[0033] Both ends of the bottom of the fixed frame 9 are rotatably connected to the first rocker plate 18 via the fourth rotating shaft 17. Both ends of the top of the first rocker plate 18 are provided with sliding grooves 22. Each sliding groove 22 is slidably connected to the inside of a fixed shaft 21. The tops of the two fixed shafts 21 are respectively fixedly connected to the second rocker plate 19 and the third rocker plate 20. The third rocker plate 20 is located below the gear 11 and is meshed with the adjacent gear 11. The top of the second rocker plate 19 away from the fixed shaft 21 is fixedly connected to the push plate 23.

[0034] An arc rod 24 is fixedly connected to the bottom of the driven auxiliary plate 6 away from the second rotating shaft 5. The inner bottom of the groove 4 is provided with a matching arc groove 25 corresponding to the arc rod 24. The end of the arc rod 24 away from the driven auxiliary plate 6 passes through the arc groove 25 and contacts the push plate 23.

[0035] A locking bolt 8 is inserted into the side wall of the fixing frame 9 away from the horizontal plate 7. The locking bolt 8 passes through one end of the fixing frame 9 and is threaded to the adjacent horizontal plate 7. The fixing frame 9 is connected to the horizontal plate 7 by the locking bolt 8, which can effectively make the fixing frame 9 easier to assemble and disassemble.

[0036] The support plate 1 and the flip plate 3 have a first adapter groove 15 and a second adapter groove 16 respectively on the side wall of the first rotating shaft 2 near the first rotating shaft 2, corresponding to the transmission wheel 14. When the first rotating shaft 2 rotates, it can drive the transmission wheel 14 on the shaft wall to rotate.

[0037] The arc rod 24 is coaxially arranged with the second rotating shaft 5, so that when the arc rod 24 is pushed by the push plate 23, it can drive the driven auxiliary plate 6 to flip upward inside the groove 4 through the coaxial second rotating shaft 5.

[0038] The end of the driven auxiliary plate 6 away from the second rotating shaft 5 is arc-shaped. Its arc-shaped structure is coaxial with the second rotating shaft 5, which makes the driven auxiliary plate 6 more smoothly flip upward with the second rotating shaft 5 as the axis inside the groove 4.

[0039] Both ends of the bottom of the two horizontal plates 7 are fixedly connected to support frames, and the length of the support frames is greater than the thickness of the fixed frame 9. The support frames can support the support plate 1 and the flip plate 3 through the horizontal plates 7.

[0040] In use, the patient is positioned on the support plate 1 and two flipping plates 3. When the patient needs to be turned over, one of the flipping plates 3 is pushed upwards. Pushing the flipping plate 3 causes it to flip upwards around the first rotating shaft 2. The first rotating shaft 2 then drives the transmission wheel 14 to rotate. The rotation of the transmission wheel 14, via the transmission belt 13, drives the gear 11 to rotate. The rotation of the gear 11 causes the meshing third rocker plate 20 to move horizontally. The movement of the third rocker plate 20 causes the second rocker plate 19 at the other end of the first rocker plate 18 to move in the opposite direction. The device can push the arc rod 24 through the top push plate 23 to rotate the driven auxiliary plate 6 upward around the second rotation axis 5. After being rotated, the driven auxiliary plate 6 can provide auxiliary support for the patient and effectively protect the patient. No additional medical staff are needed to support the patient, which can effectively save medical manpower. While the driven auxiliary plate 6 is providing auxiliary support for the patient, medical staff can use the gaps between the driven auxiliary plates 6 to perform rehabilitation massage or wipe the patient's body. Moreover, there is no need to use a motor or cylinder as a drive unit, which can effectively reduce the cost of the turning assist device and save resources.
