Description

Technical Field

[0001] This invention relates to the field of medical turning-over assistive equipment technology, specifically a turning-over assistive device for the treatment of cardiovascular and cerebrovascular diseases. Background Technology

[0002] Turning assistance devices for the treatment of cardiovascular and cerebrovascular diseases are suitable for use by patients with these conditions. Due to the special nature of their conditions, such as poor exercise tolerance, orthostatic hypotension, and high risk of thrombosis, these patients have stricter requirements for the safety, comfort, and functionality of turning assistance devices. These devices must meet basic turning functions while avoiding fluctuations in cardiovascular and cerebrovascular load caused by sudden changes in position, thus reducing the risk of accidents. However, existing turning assistance devices have some shortcomings, such as: Application No. CN202310853152.5 describes a pressure ulcer prevention and assistive turning device for bedridden patients in cardiovascular surgery. This device ensures that the patient remains in a side-lying position in the middle of the bed after turning, preventing instability and falls, thus guaranteeing patient safety during turning. It also prevents excessive turning that could lead to prostrate or fall-off positions, avoiding secondary injuries. However, in actual use, it is difficult to provide adequate back support, which may result in insufficient support when assisting with turning, requiring manual assistance and reducing the device's turning efficiency. Application No.: CN201911010614.7 describes a turning assistance device for cardiovascular treatment. This device causes the patient's body to tilt downwards by extracting air from the left or right support airbag. However, in actual use, the device is difficult to support the user's back after turning over, which may lead to a lack of support and the need for manual assistance.

[0003] Therefore, we propose a turning assist device for the treatment of cardiovascular and cerebrovascular diseases in order to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide a turning assistance device for the treatment of cardiovascular and cerebrovascular diseases, so as to solve the problem mentioned in the background art that current turning assistance devices on the market are difficult to support the user's back, which may lead to a lack of support when the user turns over and reduce the efficiency of turning over.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a turning assistance device for the treatment of cardiovascular and cerebrovascular diseases, comprising a device body and a headboard located at the right end of the device body, wherein a bed board is provided on the top of the device body, and a mattress is provided at the right end of the bed board; The main body of the device is equipped with a drive mechanism, and the top of the drive mechanism is equipped with two sets of flipping mechanisms. The flipping mechanism includes a rotating rod, and the middle of the rotating rod is equipped with a buffer damping. The top of the rotating rod is connected to a rotating plate through a hinge. The outer side of the rotating plate is equipped with a connecting shaft, and the connecting shaft is rotatably connected to the bottom of the mattress. The main body of the device is equipped with two sets of air cushions at the top and a pressurizing mechanism at the bottom of the air cushions. The pressurizing mechanism includes a Roots pump housing, inside which are two sets of Roots pump rods. A diversion pipe is connected to the outside of the Roots pump rods and is connected to the air cushion pipe. The other end of the Roots pump housing is connected to a pressure box.

[0006] By simultaneously driving the flipping mechanism and the pressurizing mechanism through the drive mechanism, the rotating rod, in conjunction with the buffer damping, drives the rotating plate to rise and fall. The rotating plate rotates around the connecting shaft as the center, thereby enabling the two sets of rotating plates to help the user turn over. At the same time, the Roots pump rod in the pressurizing mechanism also rotates inside the Roots pump housing, so that the air pressure is transmitted to the air cushion through the diverter pipe. This causes the air cushion to expand and support the user's back, thus avoiding the problem of the user failing to turn over due to lack of support. This increases the turning efficiency of the device during use.

[0007] As a preferred technical solution of the present invention, the main body of the device is fixedly connected to the drive mechanism, and the drive mechanism includes a drive motor, and a first sprocket is connected to the right end of the drive motor. A chain is engaged on the outside of the first sprocket, and a second sprocket is engaged on the other end of the chain. A first drive shaft is connected to the right end of the first sprocket, and two sets of first bevel gears are engaged on the outside of the first drive shaft.

[0008] The above technical solution enables the drive motor to drive the first drive shaft and the rotating shaft synchronously through the transmission of sprockets and chains, realizing the coordinated action of the flipping mechanism, the pressurizing mechanism and the foot fixing structure, which increases the stability of the equipment during operation. Furthermore, through the setting of the first bevel gear set, the rotational motion of the first drive shaft can be converted into the lateral driving force of the threaded shaft, providing stable power for the flipping mechanism.

[0009] As a preferred technical solution of the present invention, the front end of the first bevel gear set is connected to a threaded shaft, and two sets of threaded sleeves are provided on the outside of the threaded shaft. The top of the threaded sleeves is rotatably connected to the rotating rod. The main body of the device is provided with a sliding shaft, and the sliding shaft is slidably connected to the threaded sleeves.

[0010] The above technical solution enables the two sets of threaded sleeves to move in the same direction along the sliding shaft when the threaded shaft rotates, and the rotating plate is pushed by the rotating rod to rotate smoothly around the connecting shaft, thereby increasing the stability of the equipment when it is rotating.

[0011] As a preferred technical solution of the present invention, the threaded shaft can drive two sets of threaded sleeves to move left and right in the same direction, and the top of the rotating plate is provided with a soft pad, and the soft pad is in contact with the outer side of the air cushion, and the outer side of the connecting mattress is in contact with the rotating plate and the soft pad.

[0012] The above technical solution allows the soft pad and the connecting mattress to fit together, which can distribute the pressure on the patient's body. Combined with the support of the air cushion, it can prevent pressure sores when turning over and improve the patient's comfort.

[0013] As a preferred technical solution of the present invention, the bottom of the air cushion is fixedly connected to the main body of the device, and a second bevel gear set is provided on the outside of the first drive shaft, and the front end of the second bevel gear set is connected to the second drive shaft, and two sets of third bevel gear sets are provided on the outside of the second drive shaft.

[0014] The above technical solution enables the first drive shaft to transmit power to the second drive shaft through the second bevel gear set, realizing the linkage control of the pressurization mechanism and the turning mechanism; the two sets of third bevel gear sets can drive the Roots pump rods on the corresponding sides respectively, realizing the precise inflation of the single-sided air cushion and adapting to the support needs of patients in different turning directions.

[0015] As a preferred embodiment of the present invention, the bottom of the third bevel gear set is fixedly connected to a set of first gears, and a second gear meshes with the outer side of the first gears. The bottoms of the first gears and the second gears are fixedly connected to a set of Roots pump rods.

[0016] The above technical solution enables the gear meshing transmission to drive the two sets of Roots pump rods to rotate in opposite directions inside the Roots pump casing, generating stable air pressure, thereby increasing the stability of the equipment when transmitting air pressure.

[0017] As a preferred technical solution of the present invention, the second drive shaft is rotatably connected to the inside of the device body, and the gears of the two sets of third bevel gears face opposite directions. The Roots pump housing is connected to the air pressure box pipeline through a connecting valve, and the Roots pump housing is connected to the air cushion pipeline through a diverter pipe. The air cushion is protected by a soft rubber layer on top.

[0018] The above technical solution allows the pressure box to store spare gas, ensuring the inflation speed of the air cushion; and the soft rubber layer avoids friction damage caused by direct contact between the air cushion and the patient's skin, improving the safety of use.

[0019] As a preferred technical solution of the present invention, the main body of the device is fixedly connected to the pressure box, and a rotating shaft is fixedly connected to the outside of the second sprocket. A foot protection fixing pad is connected to the right end of the rotating shaft. The foot protection fixing pad is provided with a foot groove inside, and the foot protection fixing pad is rotatably connected to the top of the main body of the device.

[0020] The above technical solution enables the second sprocket to drive the rotating shaft to rotate synchronously, and drives the foot protection fixing pad to adjust its angle in conjunction with the turning action, thereby increasing the stability of the equipment during operation.

[0021] As a preferred technical solution of the present invention, the rotating shaft is rotatably connected to the inside of the device body, and the foot protection fixing pad is located on the top of the bed board. The top of the device body is provided with two sets of guardrails, the bottom of the guardrails is connected to the device body by rotating buckles, and the bottom of the device body is provided with feet. The guardrails are located on the outside of the bed board.

[0022] The above technical solution enables the rotating connection of the rotating buckle to ensure that the foot protection fixing pad rotates flexibly and adapts to the turning action; the guardrail can be quickly unfolded or retracted through the rotating buckle. When turning over, it unfolds to form a protective barrier to prevent the patient from falling out of bed, and when not in use, it is retracted to save space.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: by driving the flipping mechanism and the pressurizing mechanism simultaneously through the driving mechanism, when the rotating rod, in conjunction with the buffer damping, drives the rotating plate to rise and fall, the rotating plate rotates around the connecting shaft as the center, thereby enabling the two sets of rotating plates to carry the user to perform the flipping operation. In addition, the Roots pump rod in the pressurizing mechanism also rotates inside the Roots pump housing, thereby enabling the air pressure to be transmitted to the air cushion through the diverter pipe, thereby causing the air cushion to expand and support the user's back, thus avoiding the problem of the user failing to flip due to the lack of support behind their back during the flipping process, and increasing the flipping efficiency of the device during use. Furthermore, by setting up the drive mechanism, the drive motor can drive the first drive shaft and the rotating shaft synchronously through the transmission of sprockets and chains, realizing the coordinated action of the flipping mechanism, the pressurizing mechanism and the foot fixing structure, which increases the stability of the equipment during operation. Moreover, by setting up the first bevel gear set, the rotational motion of the first drive shaft can be converted into the lateral driving force of the threaded shaft, providing stable power for the flipping mechanism. Furthermore, the guardrails can be quickly unfolded or retracted by rotating the buckles. When turning over, they unfold to form a protective barrier to prevent patients from falling out of bed, and when not in use, they can be retracted to save space. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Please see Figures 1-10 The present invention provides a technical solution: a turning assistance device for the treatment of cardiovascular and cerebrovascular diseases, including a device body 1 and a headboard 2 set at the right end of the device body 1, a bed board 3 is provided on the top of the device body 1, and a mattress 4 is provided at the right end of the bed board 3. The main body 1 of the device is equipped with a drive mechanism, and the top of the drive mechanism is equipped with two sets of flipping mechanisms. The flipping mechanism includes a rotating rod 14, and the middle of the rotating rod 14 is equipped with a buffer damping 15. The top of the rotating rod 14 is connected to a rotating plate 17 through a hinge. The outer side of the rotating plate 17 is equipped with a connecting shaft 16, and the connecting shaft 16 is rotatably connected to the bottom of the connecting mattress 4. The main body 1 of the device is provided with two sets of air cushions 27 at the top, and a pressurizing mechanism is provided at the bottom of the air cushions 27. The pressurizing mechanism includes a Roots pump housing 25. The Roots pump housing 25 is provided with two sets of Roots pump rods 24 inside, and a diversion pipe 26 is connected to the outside of the Roots pump rods 24. The diversion pipe 26 is connected to the air cushions 27. The other end of the Roots pump housing 25 is connected to a pressure box 28. The main body 1 of the device is fixedly connected to the drive mechanism, and the drive mechanism includes a drive motor 5. The right end of the drive motor 5 is connected to a first sprocket 6. A chain 7 is engaged on the outside of the first sprocket 6, and a second sprocket 8 is engaged on the other end of the chain 7. The right end of the first sprocket 6 is connected to a first drive shaft 9, and two sets of first bevel gears 10 are engaged on the outside of the first drive shaft 9. The front end of the first bevel gear set 10 is connected to a threaded shaft 11, and two sets of threaded sleeves 12 are provided on the outside of the threaded shaft 11. The top of the threaded sleeves 12 is rotatably connected to the rotating rod 14. The main body 1 of the device is provided with a sliding shaft 13, and the sliding shaft 13 is slidably connected to the threaded sleeves 12. The drive mechanism is activated, causing both sets of flipping mechanisms to operate simultaneously. This causes the damping 15 in the rotating rod 14 of one flipping mechanism to retract, and the rotating rod 14 then pushes up the rotating plate 17, causing the rotating plate 17 to rotate around the connecting shaft 16. This allows the rotating plate 17 to push the user over. Meanwhile, the rotating rod 14 in the other flipping mechanism causes the damping 15 to extend, bringing the rotating plate 17 and the bed board 3 into a horizontal position. At the same time, the drive mechanism also... The pressurization mechanism is activated, causing the Roots pump rod 24 in the pressurization mechanism to rotate forward inside the Roots pump housing 25. This causes the Roots pump housing 25 to transfer the air pressure inside the pressure box 28 to the inside of the diversion pipe 26. The air pressure is then transferred to a set of air cushions 27 through the diversion pipe 26 to support the user's back. Meanwhile, the other pressurization mechanism rotates in the opposite direction, causing the Roots pump rod 24 to rotate in the opposite direction inside the Roots pump housing 25. This transfers part of the air pressure in the other set of air cushions 27 to the pressure box 28. When the drive motor is started, the drive motor 5 drives the first sprocket 6 to rotate, which in turn drives the first drive shaft 9 to rotate. The first drive shaft 9 then drives the first bevel gear set 10 and the threaded shaft 11 to rotate, which in turn drives the two sets of threaded sleeves 12 to move in the same direction. This causes the threaded sleeves 12 to drive the rotating rod 14 to move, thereby controlling the operation of the two sets of flipping mechanisms. The first drive shaft 9 also drives the second bevel gear set 19 to rotate, which in turn drives the second drive shaft 20 and the two sets of third bevel gear sets 21 to rotate. Since the third bevel gear sets 21 are facing opposite directions, the two sets of third bevel gear sets 21 can drive the pressurizing mechanism to rotate in the forward or reverse direction. The third bevel gear sets 21 also drive the first gear 22 to rotate, which in turn drives the second gear 23 to rotate. This allows the first gear 22 and the second gear 23 to simultaneously drive the Roots pump rod 24 to rotate inside the Roots pump housing 25. The threaded shaft 11 can drive two sets of threaded sleeves 12 to move left and right in the same direction, and the top of the rotating plate 17 is provided with a soft pad 18, and the soft pad 18 is in contact with the outside of the air cushion 27. The outside of the connecting mattress 4 is in contact with the rotating plate 17 and the soft pad 18. The bottom of the air cushion 27 is fixedly connected to the main body 1 of the device, and a second bevel gear set 19 is provided on the outside of the first drive shaft 9, and the front end of the second bevel gear set 19 is connected to the second drive shaft 20. Two sets of third bevel gear sets 21 are provided on the outside of the second drive shaft 20. The bottom of the third bevel gear set 21 is fixedly connected to a set of first gears 22, and the outer side of the first gears 22 is meshed with a second gear 23. The bottom of the first gears 22 and the second gears 23 are fixedly connected to a set of Roots pump rods 24. The second drive shaft 20 is rotatably connected to the inside of the device body 1, and the gears of the two sets of third bevel gear sets 21 face opposite directions. The Roots pump housing 25 is connected to the air pressure box 28 through a connecting valve. The Roots pump housing 25 is connected to the air cushion 27 through a diversion pipe 26. The air cushion 27 is protected by a soft rubber layer on top. The device body 1 is fixedly connected to the air pressure box 28, and a rotating shaft 29 is fixedly connected to the outside of the second sprocket 8. The right end of the rotating shaft 29 is connected to a foot protection fixing pad 30. The foot protection fixing pad 30 has a foot fixing groove 31 inside, and the foot protection fixing pad 30 is rotatably connected to the top of the device body 1. The rotating shaft 29 is rotatably connected to the inside of the device body 1, and the foot fixing pad 30 is located on the top of the bed board 3. The top of the device body 1 is provided with two sets of guardrails 32. The bottom of the guardrails 32 is connected to the device body 1 by rotating buckles. The bottom of the device body 1 is provided with feet 33, and the guardrails 32 are located on the outside of the bed board 3.

[0028] Working principle: When using the turning assist device for the treatment of cardiovascular and cerebrovascular diseases, it is first connected to an external power source. Then, the drive mechanism drives two sets of turning mechanisms to operate simultaneously. This causes the damping 15 in the rotating rod 14 of one turning mechanism to contract, and the rotating rod 14 pushes up the rotating plate 17, causing the rotating plate 17 to rotate around the connecting shaft 16. This allows the rotating plate 17 to push the user to turn over. Meanwhile, the rotating rod 14 in the other turning mechanism causes the damping 15 to extend, thus allowing the rotating plate 17 and the bed board to... 3 is in a horizontal state, and at the same time, the drive mechanism will also drive the pressurization mechanism to run, so that the Roots pump rod 24 in the pressurization mechanism rotates in the forward direction inside the Roots pump housing 25, so that the Roots pump housing 25 transmits the air pressure inside the pressure box 28 to the inside of the diversion pipe 26, and transmits the air pressure to a set of air cushions 27 through the diversion pipe 26 to support the user's back. Meanwhile, the other pressurization mechanism will rotate in the opposite direction, so that the Roots pump rod 24 rotates in the opposite direction inside the Roots pump housing 25, and transmits part of the air pressure in the other set of air cushions 27 to the pressure box 28. The first sprocket 6 drives the first drive shaft 9 to rotate, and the two sets of first bevel gears 10 on its outer side transmit power to the threaded shaft 11, causing the threaded shaft 11 to drive the two sets of threaded sleeves 12 to move in the same direction along the sliding shaft 13. The rotating rod 14 at the top of the threaded sleeve 12 then pushes the rotating plate 17 to rotate around the connecting shaft 16. When the left rotating plate 17 rises, the right rotating plate 17 falls synchronously. The buffer damper 15 in the middle of the rotating rod 14 buffers the impact force of the rotation through elastic deformation, avoiding the sudden change of body position from putting a burden on the patient's cardiovascular system. The first drive shaft 9 drives the second drive shaft 20 to rotate via the second bevel gear set 19. The two sets of third bevel gear sets 21 respectively drive the first gear 22 and the second gear 23 on the corresponding side to mesh and transmit power. If the patient turns to the left, the left Roots pump rod rotates in the forward direction, pushing the gas in the pressure box 28 into the left air cushion 27 through the diversion pipe 26, causing it to expand and support the patient's back; the right Roots pump rod rotates in the reverse direction, drawing the gas in the right air cushion 27 back into the pressure box 28 to avoid obstructing the turning. When the drive mechanism is running, the drive motor 5 drives the first sprocket 6 to rotate, which in turn drives the first drive shaft 9 to rotate. The first drive shaft 9 then drives the first bevel gear set 10 and the threaded shaft 11 to rotate, which in turn drives the two sets of threaded sleeves 12 to move in the same direction. This causes the threaded sleeves 12 to drive the rotating rod 14 to move, thereby controlling the operating state of the two sets of flipping mechanisms. The first drive shaft 9 also drives the second bevel gear set 19 to rotate, which in turn drives the second drive shaft 20 and the two sets of third bevel gear sets 21 to rotate. Since the third bevel gear sets 21 are facing opposite directions, the two sets of third bevel gear sets 21 can drive the pressurizing mechanism to rotate in the forward or reverse direction. The third bevel gear sets 21 also drive the first gear 22 to rotate, which in turn drives the second gear 23 to rotate. This allows the first gear 22 and the second gear 23 to simultaneously drive the Roots pump rod 24 to rotate inside the Roots pump housing 25. During the turning process, the user's feet can be placed inside the foot groove 31 inside the foot protection fixing pad 30. When the drive mechanism is running, the first sprocket 6 will also drive the second sprocket 8 to rotate through the chain 7, so that the second sprocket 8 drives the foot protection fixing pad 30 to rotate through the rotating shaft 29, thereby cooperating with the turning mechanism to turn the user over. During the turning process, the soft pad 18 on top of the rotating plate 17 fits against the connected mattress 4, distributing pressure on the patient's body and working in conjunction with the soft rubber layer of the air cushion 27 to prevent pressure sores. Once the patient is in position, the drive motor 5 stops running, the air cushion 27 remains in a supporting state, and the guardrail 32 continues to provide protection. If resetting is required, the drive mechanism reverses, all components return to their initial state, and the guardrail can be retracted to complete one turning operation.
