Improved turning-over device for geriatric care

Abstract

This invention discloses an improved geriatric nursing turning device, belonging to the field of medical device technology. It includes a support frame, with rectangular frames connected to both ends. Each rectangular frame has a support base connected to both sides of its lower end. Through the synchronous linkage design of the turning component and the side-lying support component, the turning action and cushioning support are coordinated. The turning board rotates gradually under the drive of a first drive motor, while the support plate of the side-lying support component rotates synchronously through a rotating component, forming a cushioning support angle that conforms to the patient's body. This effectively alleviates the impact of sudden changes in the center of gravity during turning, avoiding traction pain or fracture risks in elderly patients due to osteoporosis and joint degeneration. Furthermore, the cushioning pad added to the surface of the turning board further reduces skin friction and local pressure concentration. Combined with the limiting effect of the L-shaped guardrail, it prevents the patient from sliding and shifting during turning, significantly improving operational safety.

Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to an improved turning device for geriatric nursing. Background Technology

[0002] In geriatric clinical nursing, elderly patients are prone to complications such as pressure sores, lung infections, and poor blood circulation when they are bedridden for a long time due to physical decline, osteoporosis, and limited limb movement. Therefore, regular turning over is a core basic operation in geriatric nursing.

[0003] Manual turning requires the coordinated efforts of caregivers, which is not only labor-intensive and inefficient, but also difficult to control precisely in terms of force and angle. Improper operation can easily lead to joint strain and skin abrasion damage to the patient. This is especially true for elderly patients who are obese, hemiplegic, or have fractures, where the safety and comfort of manual turning are even more difficult to guarantee. At the same time, it is difficult to maintain the patient's side-lying position during manual turning, which makes subsequent operations such as back pressure ulcer care and bed sheet changing inconvenient. Frequent handling can also cause fluctuations in the patient's heart rate and blood pressure, increasing the risk of cardiovascular events. Summary of the Invention

[0004] The purpose of this invention is to provide an improved turning device for geriatric care to solve the problems mentioned in the background art.

[0005] An improved geriatric nursing turning device includes a support frame, with rectangular frames connected to both ends of the support frame, and support bases connected to both sides of the lower end of each rectangular frame. A turning component is connected to the upper end of the support frame, and a first rotating component is connected to one side of each end of the turning component. A first side-lying support component is connected to the end of the first rotating component away from the turning component. The turning component includes a first circular rotating rod, both ends of which are connected to a first gear, and the middle part of each first gear is connected to a first drive motor; The first rotating assembly includes a telescopic assembly. The end of the telescopic assembly away from the turning assembly is connected to a first rotating belt. The end of the first rotating belt away from the telescopic assembly is connected to a secondary rotating wheel. The end of the secondary rotating wheel facing the turning assembly is connected to a first rotating wheel. The outer side of the first rotating wheel is connected to a second rotating belt.

The inner surfaces of the two rotating belts are provided with a plurality of rectangular connecting grooves. The outer sides of the secondary rotating wheel and the two rotating wheels are all connected to a third rectangular connecting block. The two rotating belts are connected to the secondary rotating wheel and the two rotating wheels respectively by engaging with the third rectangular connecting block through the rectangular connecting grooves on their inner wall surfaces. The first side-lying support assembly includes an L-shaped guardrail, the outer surface of which has a plurality of first ventilation holes, and a second circular rotating rod connected to the end of the L-shaped guardrail facing the turning assembly, the two ends of which have connecting grooves.

[0006] Preferably, the end of the turning-over component away from the first rotating component is connected to a second rotating component, and the end of the second rotating component away from the turning-over component is connected to a second side-lying support component.

[0007] Preferably, a plurality of first rectangular rotating rods are connected to one side of the first circular rotating rod facing the first rotating assembly, and a first flipping plate is connected to the outer surface of the first rectangular rotating rod. A first rectangular groove is provided at the intersection of the first flipping plate and the first rectangular rotating rod.

[0008] Preferably, a plurality of second rectangular rotating rods are connected to one side of the first circular rotating rod facing the second rotating assembly. A second flipping plate is connected to the outer side of the upper end of the second rectangular rotating rod. A second rectangular groove is provided at the intersection of the second flipping plate and the second rectangular rotating rod. A telescopic block is connected to the end of the upper surface of the first flipping plate facing the first circular rotating rod and the end of the upper surface of the second flipping plate facing the first circular rotating rod. Two first drive motors are installed in the inner cavity of the rectangular frame.

[0009] Preferably, the telescopic assembly includes a third gear, a groove is formed in the inner cavity of the third gear, a third circular rotating rod is connected to the inner cavity of the groove, an electric telescopic rod is connected to the end of the third circular rotating rod away from the third gear, and a driving wheel is meshed on the outer side of the third gear, and the structure of the driving wheel is the same as that of the secondary driving wheel. Several fifth rectangular connecting blocks are connected to the outer side of the end of the third gear facing the driving wheel, and several second connecting grooves are formed on the inner wall surface of the driving wheel. The fifth rectangular connecting blocks fit into the second connecting grooves, and the length of the second connecting grooves is greater than that of the fifth rectangular connecting blocks. When the electric telescopic rod retracts, the fifth rectangular connecting blocks move along the second connecting grooves toward the electric telescopic rod. When the fifth rectangular connecting blocks move to one end of the second connecting grooves, the third gear meshes with the first gear. The driving wheel, the first rotating belt, and the secondary driving wheel constitute a first rotating group, and the first rotating wheel, the second rotating belt, and the second rotating wheel constitute a second rotating group.

[0010] Preferably, the third gear is initially separated from the first gear, the radius of the driving gear is equal to one-third of the radius of the secondary driving gear, and the components of the second rotating assembly are the same as those of the first rotating assembly.

[0011] Preferably, a support plate is sleeved on the outer side of the second circular rotating rod, and a plurality of second ventilation holes are opened on the outer surface of the support plate. The components of the second side-lying support assembly are the same as those of the first side-lying support assembly, and a fourth rectangular connecting block is connected to the outer surface of both ends of the second circular rotating rod.

[0012] Preferably, the connecting block in the first rotating assembly coincides with the connecting groove in the first lateral support assembly, and the connecting block in the second rotating assembly coincides with the connecting groove in the second lateral support assembly.

[0013] Compared with the prior art, the advantages of this invention are: 1. In this invention, the synchronous linkage design of the turning-over component and the side-lying support component enables the coordinated performance of turning-over action and cushioning support. The turning-over board rotates gradually under the drive of the first drive motor, while the support plate of the side-lying support component rotates synchronously through the rotation component transmission, forming a cushioning support angle that conforms to the patient's body. This effectively alleviates the impact of sudden changes in the center of gravity during turning-over and avoids the risk of traction pain or fractures in elderly patients due to osteoporosis and joint degeneration. In addition, the cushioning pad added to the surface of the turning-over board further reduces skin friction and local pressure concentration. Combined with the limiting effect of the L-shaped guardrail, it prevents the patient from sliding and shifting during turning-over, significantly improving operational safety.

[0014] 2. In this invention, the gear clutch structure of the telescopic component enables integrated linkage of turning and support functions, eliminating the need for additional manual adjustment of support components and simplifying the operation process. Furthermore, the turning board can be independently controlled to reset. When changing the second turning board sheet, only the corresponding side rotation component needs to be controlled to reset, while the other side remains supported. Sheet changing can be completed without moving the patient. In addition, electric drive replaces manual effort, and the entire process of turning, supporting, and resetting can be completed simply by controlling the drive motor and electric telescopic rod, significantly reducing the physical exertion of nursing staff and improving nursing efficiency.

[0015] 3. In this invention, the rotating component adopts a gear clutch and dual rotating group transmission design. The radius ratio of the driving wheel and the secondary driving wheel can achieve precise control of the rotation angle, ensuring the coordination of the turning board and the support board. At the same time, both the first and second lateral support components are equipped with a first ventilation hole and a second ventilation hole to form a two-way ventilation channel, which can quickly dissipate the damp heat from the part of the patient in contact with the support surface, keep the skin dry, and reduce the risk of pressure sores from the root.

[0018] Example: Please refer to Figure 1 and Figure 2 An improved geriatric nursing turning device includes a support frame 1, with rectangular frames 2 connected to both ends of the support frame 1. Support bases 3 are connected to both sides of the lower end of each rectangular frame 2. A turning component 4 is connected to the upper end of the support frame 1. A first rotating component 5 is connected to one side of both ends of the turning component 4. A first side-lying support component 6 is connected to the end of the first rotating component 5 away from the turning component 4. Please see Figure 3 and Figure 4 The turning component 4 includes a first circular rotating rod 401, both ends of which are connected to a first gear 406, and the middle part of each first gear 406 is connected to a first drive motor 408. Please see Figure 5 and Figure 6The first rotating component 5 includes a telescopic component 501. The end of the telescopic component 501 away from the turning component 4 is connected to a first rotating belt 502. The end of the first rotating belt 502 away from the telescopic component 501 is connected to a secondary rotating wheel 503. The end of the secondary rotating wheel 503 facing the turning component 4 is connected to a first rotating wheel 504. The outer side of the first rotating wheel 504 is connected to a second rotating belt 505. The end of the second rotating belt 505 away from the first rotating wheel 504 is connected to a second rotating wheel 506. The end of the second rotating wheel 506 facing the first side-lying support component 6 is connected to a connecting block 507. Several rectangular connecting grooves are opened on the inner surface of the two rotating belts. The outer side of the secondary rotating wheel 503 and the two rotating wheels are connected to a third rectangular connecting block. The two rotating belts are connected to the secondary rotating wheel 503 and the two rotating wheels respectively through the rectangular connecting grooves opened on the inner wall surface and the third rectangular connecting block. Please see Figure 7 and Figure 8 The first side-lying support component 6 includes an L-shaped guardrail 601. The outer surface of the L-shaped guardrail 601 is provided with a plurality of first ventilation holes 602. The end of the L-shaped guardrail 601 facing the turning component 4 is connected to a second circular rotating rod 603. The two ends of the second circular rotating rod 603 are provided with connecting grooves 604.

[0019] Specifically, through the synchronous linkage design of the turning component 4 and the side-lying support component, the turning action and cushioning support are coordinated. The turning board rotates gradually under the drive of the first drive motor 408, while the support plate 605 of the side-lying support component rotates synchronously through the rotation component transmission, forming a cushioning support angle that fits the patient's body. This effectively alleviates the impact of sudden changes in the center of gravity during turning and avoids the risk of traction pain or fractures in elderly patients due to osteoporosis and joint degeneration. In addition, the cushioning pad added to the surface of the turning board further reduces skin friction and local pressure concentration. Combined with the limiting effect of the L-shaped guardrail 601, it prevents the patient from sliding and shifting during turning, significantly improving the safety of operation.

[0020] Please see Figure 1 and Figure 2 The end of the turning component 4 away from the first rotating component 5 is connected to the second rotating component 7, and the end of the second rotating component 7 away from the turning component 4 is connected to the second side-lying support component 8.

[0021] Please see Figure 3 and Figure 4 A number of first rectangular rotating rods 402 are connected to one side of the first circular rotating rod 401 facing the first rotating assembly 5. A first flipping plate 403 is connected to the outer surface of the first rectangular rotating rod 402. A first rectangular groove 404 is provided at the intersection of the first flipping plate 403 and the first rectangular rotating rod 402.

[0022] Please see Figure 3 and Figure 4 A number of second rectangular rotating rods 409 are connected to the side of the first circular rotating rod 401 facing the second rotating assembly 7. The upper outer side of the second rectangular rotating rod 409 is connected to a second flipping plate 410. A second rectangular groove 411 is provided at the intersection of the second flipping plate 410 and the second rectangular rotating rod 409. A telescopic block is connected to the upper surface of the first flipping plate 403 facing the first circular rotating rod 401 and the upper surface of the second flipping plate 410 facing the first circular rotating rod 401. Two first drive motors 408 are installed in the inner cavity of the rectangular frame 2. A buffer pad is connected to the surface of the two flipping plates facing the flipping assembly 4.

[0023] Please see Figure 6 The telescopic assembly 501 includes a third gear 508, with a groove 511 formed in the inner cavity of the third gear 508. A third circular rotating rod 510 is connected to the inner cavity of the groove 511. An electric telescopic rod 509 is connected to the end of the third circular rotating rod 510 away from the third gear 508. A drive wheel 512 meshes with the outer side of the third gear 508, and the structure of the drive wheel 512 is the same as that of the secondary drive wheel 503. Several fifth rectangular connecting blocks are connected to the outer side of the end of the third gear 508 facing the drive wheel 512. Several second connecting grooves are formed on the inner wall surface of the drive wheel 512. The fifth rectangular connecting blocks fit into the second connecting grooves. The second connecting grooves are large. Regarding the length of the fifth rectangular connecting block, when the electric telescopic rod 509 retracts, the fifth rectangular connecting block will move along the second connecting groove toward the electric telescopic rod 509. When the fifth rectangular connecting block moves to one end of the second connecting groove, the third gear 508 will mesh with the first gear 406. The driving wheel 512, the first rotating belt 502, and the secondary driving wheel 503 constitute the first rotating group. The first rotating wheel 504, the second rotating belt 505, and the second rotating wheel 506 constitute the second rotating group. The third circular rotating rod 510 is rotatably connected to the third gear 508. The end of the third circular rotating rod 510 away from the electric telescopic rod 509 coincides with the groove 511.

[0024] Specifically, the gear clutch structure of the telescopic component 501 enables integrated linkage of turning and support functions, eliminating the need for manual adjustment of support components and simplifying the operation process. Furthermore, the turning board can be independently controlled to reset. When changing the bed sheet on the second turning board 410, only the corresponding side rotation component needs to be controlled to reset, while the other side remains supported. Bed sheet changes can be completed without moving the patient. In addition, electric drive replaces manual effort. The entire process of turning, supporting, and resetting can be completed simply by controlling the drive motor and the electric telescopic rod 509, significantly reducing the physical exertion of nursing staff and improving nursing efficiency.

[0025] Please see Figure 5 and Figure 6 The third gear 508 is initially separated from the first gear 406. The radius of the driving gear 512 is equal to one-third of the radius of the secondary driving gear 503. The components of the second rotating assembly 7 are the same as those of the first rotating assembly 5.

[0026] Please see Figure 7 and Figure 8 A support plate 605 is sleeved on the outer side of the second circular rotating rod 603. Several second ventilation holes 606 are opened on the outer surface of the support plate 605. The components of the second side-lying support assembly 8 are the same as those of the first side-lying support assembly 6. The outer surfaces of both ends of the second circular rotating rod 603 are connected to fourth rectangular connecting blocks. The fourth rectangular connecting blocks are connected to the outer surface of the L-shaped guardrail 601.

[0027] The connecting block 507 in the first rotating assembly 5 coincides with the connecting groove 604 in the first lateral support assembly 6, and the connecting block 507 in the second rotating assembly 7 coincides with the connecting groove 604 in the second lateral support assembly 8.

[0028] Specifically, the rotating assembly adopts a gear clutch and dual-rotation group transmission design. The radius ratio of the driving wheel 512 and the secondary driving wheel 503 can achieve precise control of the rotation angle, ensuring the coordination of the turning board and the support board 605. At the same time, both the first lateral support assembly 6 and the second lateral support assembly 8 are equipped with a first ventilation hole 602 and a second ventilation hole 606, forming a two-way ventilation channel, which can quickly dissipate the moist heat from the area in contact with the support surface, keep the skin dry, and reduce the risk of pressure sores from the root.

[0029] Working principle: First, the patient is placed on the upper surface of the turning component 4. If the patient needs to be turned towards the first rotating component 5, the electric telescopic rod 509 in the first rotating component 5 will retract, thereby driving the third circular rotating rod 510 to retract, which in turn drives the third gear 508 to move towards the first gear 406 until the third gear 508 meshes with the first gear 406. When the third gear 508 meshes with the first gear 406, the first drive motor 408 will rotate 90 degrees towards the first rotating component 5, thereby driving the first gear 406 to rotate half a turn, which in turn drives the third gear 508 in the two rotating components to rotate, and also drives the first circular rotating rod 401 to rotate. The rotation of the first circular rotating rod 401 will drive the second rectangular rotating rod 409 to rotate towards the first rotating component 5, thereby driving the drive wheel 512 to rotate. When the drive wheel 512 in the first rotating assembly 5 rotates, it will drive the first rotating belt 502 to rotate, thereby driving the secondary drive wheel 503 to rotate by thirty degrees, which in turn drives the first rotating wheel 504 to rotate. As the first rotating wheel 504 rotates, it will drive the second rotating belt 505 to rotate, thereby driving the second rotating wheel 506 and the connecting block 507 to rotate by thirty degrees. At this time, the rotation of the connecting block 507 will drive the second circular rotating rod 603 to rotate, and then drive the support plate 605 to rotate. As the second turning board 410 rotates 90 degrees toward the first rotating component 5, the support plate 605 in the first lateral recumbent support component 6 will rotate 30 degrees toward the first circular rotating rod 401. When the second turning board 410 rotates 90 degrees, the support plate 605 will form a 30-degree angle with the L-shaped guardrail 601. At this time, due to the gradual rotation of the second turning board 410, the patient's body will gradually turn over. If the second turning board 410 is at 90 degrees, the patient's center of gravity will cause the patient to turn over, and the support plate 605 will reduce the impact force when the patient turns over, thereby reducing the injury to the patient during the turning process. At the same time, the patient will lie face down on the upper surface of the support plate 605. At this time, the nurse can clean and apply medicine to the pressure sores on the patient's back. The first ventilation hole 602 and the second ventilation hole 606 in the support assembly are ventilated until the patient's back is dry. Then, the first drive motor 408 is returned to its original position, thereby allowing the support plate 605 and the second turning board 410 to return to their original positions. At this time, the nurse can change the sheet laid on the upper part of the second turning board 410. Then, the electric telescopic rod 509 is activated to drive the third circular rotating rod 510 to perform a reset operation, which in turn drives the third gear 508 to return to its original position and disengage from the first gear 406. If it is necessary to change the sheet on the first turning board 403, the electric telescopic rod 509 in the second rotating assembly 7 will be activated to retract until the third gear 508 meshes with the first gear 406. Then, the above operations are performed synchronously until the sheet on the first turning board 403 is changed, thus ending all operations.
