Description

Technical Field

[0001] The present invention relates to the technical field of nursing auxiliary equipment, and in particular to a body position adjuster and an anti-pressure ulcer nursing bed of a medical health big data sharing platform and a method of using the same. Background Art

[0002] The formation of pressure ulcers is a complex process, resulting from the combined effects of local and systemic factors, leading to skin deformation and necrosis. Prolonged pressure on the skin can lead to poor blood flow, causing ischemia, hypoxia, and nutrient deficiencies, ultimately resulting in tissue damage. This is the primary cause of pressure ulcers, which are common in those who remain in bed or in a wheelchair for extended periods.

[0003] For example, the utility model patent with publication number CN212631093U discloses an anti-pressure sore nursing bed.

[0004] However, this technical solution still has the following deficiencies in practical applications:

[0005] 1. The baffles need to be controlled by independent drive structures to achieve the turning function, which significantly increases the overall manufacturing cost. Medical staff or family members need to go around to the corresponding side of the bed to operate, which is a cumbersome process.

[0006] 2. Because the patient's back is continuously pressed against the surface of the bed, local tissue ischemia and hypoxia occur, which in turn causes pressure sores, and the back support area cannot be dynamically adjusted according to the patient's body position requirements.

[0007] In response to the above problems, the present invention document proposes a pressure ulcer prevention nursing bed with a body position adjuster and a medical health big data sharing platform and a method of using the same. Summary of the Invention

[0008] The purpose of the present invention is to solve the shortcomings of the existing technology, such as the inability to change the position of the patient's back against the bed board according to the situation, the cumbersome operation when rotating the corresponding two baffles, and the need to use two corresponding driving structures to drive the two baffles to rotate, and to propose a body position adjuster and a medical health big data sharing platform for anti-pressure ulcer nursing bed and a method of using the same.

[0011] As a further improvement of the above technical solution:

[0012] The lifting structure also includes: a lifting groove arranged in the supporting bed board, a rotating shaft is slidably connected in the lifting groove, and the rubber wheels are rotatably sleeved on the outer wall of the rotating shaft in pairs; a trapezoidal lifting plate fixed to the rotating shaft, the trapezoidal lifting plate cooperates with the inclined surface of the trapezoidal extrusion plate, so that when the first screw rotates, the rubber wheels are driven to rise and fall.

[0013] It also includes a protective structure, which includes: a gear fixed to the outer wall of the first threaded rod, a sliding sleeve and a movable plate connected by a connecting rod, the sliding sleeve is threadedly sleeved on the outer wall of the second screw, and the end of the movable plate is provided with an elastically resettable latch for locking the gear when the rubber wheel descends.

[0014] The flip structure also includes: a first push plate hinged to the bottom of the left bed board and a second push plate hinged to the bottom of the right bed board, the first push plate and the second push plate are respectively rotatably connected to the first moving seat and the second moving seat threadedly connected to the first screw and the third screw.

[0015] The clamping structure also includes: a circular cavity provided in the rotating rod, two movable disks slidably connected in the circular cavity, and a conical platform connecting the two movable disks. The conical platform is driven by the second threaded rod to squeeze the pin rod and engage with the sprocket.

[0016] The diameter of the first driving sprocket is larger than that of the first sprocket, the diameter of the second driving sprocket is larger than that of the second sprocket, and the transmission angle between the chain and the sprocket is smaller than 90°.

[0020] As a further improvement of the above technical solution:

[0021] The rubber wheels roll and contact the patient's back when the supporting bed board moves, so as to reduce friction and produce a massage effect.

[0022] In this application, the method for using the anti-pressure ulcer nursing bed of the medical health big data sharing platform includes the following steps:

[0023] S1. The single-chip computer transmits patient information to the big data platform, and the platform feeds back the position adjustment information to the display screen to assist medical staff in adjusting the patient's position;

[0024] S2. Adjust the support of the bed board for the patient's back.

[0027] S5. When the left bed board is flipped, the first movable seat moves outward, and at the same time, the first movable seat pulls the right baffle upward through the second pull rope, and the right baffle blocks the side of the bed frame close to the right bed board to prevent the patient from rolling off the right bed board when the left bed board is flipped; conversely, when the right bed board is flipped, the second movable seat pulls the left baffle upward through the first pull rope to protect the patient.

[0028] Beneficial effect: In the present invention, two movable plates fixedly connected to each other are slidably connected in the circular cavity, and a conical platform is fixed on one side of the two movable plates away from each other. A plurality of pin rods are slidably passed through the rotating rod, and the pin rods cooperate with adjacent conical platforms, and one end of the second threaded rod is rotatably connected to the adjacent conical platform; the second threaded rod is rotated to drive the conical platform to move outward, and the conical platform squeezes the adjacent pin rods into the pin groove to complete the braking between the rotating rod and the first driving sprocket, and then the first lead screw can be driven to rotate by the cooperation of the rotating rod and the first driving sprocket to complete the flipping of the left bed board, and vice versa, the flipping of the right bed board can be completed, the operation is simple, and there is no need to use too many driving structures, which greatly reduces the production cost;

[0029] The present invention provides that the rotation of the left bed board is equipped with a first screw rod and a first threaded rod, the first threaded rod threadably passes through multiple supporting bed boards, the first screw rod rotates and passes through multiple supporting bed boards, and the two rubber wheels are rotatably sleeved on the outer wall of the rotating shaft, and the trapezoidal lifting plate fixedly connected to the rotating shaft is slidably connected in the lifting groove, and the trapezoidal extrusion plate is slidably connected to the bottom inner wall of the lifting groove, and the trapezoidal extrusion plate is threadedly connected to the first screw rod; the first screw rod drives the trapezoidal extrusion plate to move, which can push the rubber wheel to move up, and initially support the patient's back to avoid friction damage to the patient's back when the supporting bed board moves later; the first threaded rod drives the multiple supporting bed boards to move, adjusts the position of the supporting bed board on the patient's back, and avoids the same position being squeezed for a long time to cause pressure sores. When the supporting bed board moves, the rubber wheels not only reduce the friction between it and the back, but also can massage the back through the rubber wheels;

[0030] In the present invention, the gear is fixedly sleeved on the outer wall of the first threaded rod, and the outer wall of the second screw is threadedly sleeved with a sliding sleeve plate. One side of the connecting plate is slidably connected to a movable plate, and the movable plate and the sliding sleeve plate are rotatably connected by a connecting rod, and one end of the movable plate slides through the sliding rod provided with a latching tooth; after the second screw moves in the opposite direction and the rubber wheel is stored in the lifting groove, the cooperation between the sliding sleeve plate and the connecting rod drives the movable plate and the latching tooth to move in the direction of the gear, and the latching tooth brakes the gear to avoid friction damage to the patient's back caused by the first threaded rod driving the support bed board to move.

[0031] In the present invention, the flipping drive operation of the left bed board or the right bed board can be completed by the cooperation of the rotating rod and the second threaded rod. The operation is simple and does not require the use of excessive driving structures, which greatly reduces the production cost.

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] Example 1: Reference Figure 1-Figure 3 , adjuster, relates to the technical field of nursing auxiliary equipment, the adjuster mainly includes a bed frame 1, and the bed frame 1 is internally provided with a left bed board 2 and a right bed board 3 that are rotatably connected to each other. A plurality of support bed boards 5 are slidably provided on the side where the left bed board 2 and the right bed board 3 are close to each other, and these support bed boards 5 are used to support the patient's back. A plurality of rubber wheels 8 are arranged inside the support bed board 5, and the function of these rubber wheels 8 is to reduce the friction between the support bed board 5 and the patient's back, thereby increasing the patient's comfort. A first threaded rod 4 is rotatably connected inside the left bed board 2 and the right bed board 3, and the first threaded rod 4 is threaded through the corresponding plurality of support bed boards 5, so that the position of the support bed board 5 can be adjusted by rotating the first threaded rod 4, wherein the support bed board 5 can be designed in the following various shapes:

[0047] 1. Rectangular flat plate structure: basic form, can evenly distribute the support force;

[0048] 2. Arc-shaped surface structure: matches the physiological curvature of the human spine and reduces local pressure;

[0049] 3. Wave-shaped hollow structure: Waves are set on the surface of the board, and hollow holes are used to enhance air permeability;

[0050] 4. Trapezoidal gradient structure: The width changes gradually along the sliding direction, which is convenient for the staggered movement and adjustment of multiple plates.

[0051] Reference Figure 3-Figure 5 To adjust the height of the rubber wheels 8, both the left and right bed boards 2 and 3 are equipped with a lifting mechanism. This lifting mechanism specifically includes a first screw 11 and a second screw 12 that rotate within the left bed board 2. One end of the first screw 11 slides and extends into the interior of the second screw 12, and the first screw 11 rotates and penetrates the multiple support bed boards 5. A lifting groove 6 is provided within the support bed boards 5. A rotating shaft 7 is slidably connected within the lifting groove 6. The rubber wheels 8 are rotatably mounted on the outer wall of the rotating shaft 7 in pairs. Trapezoidal lifting plates 9 are also longitudinally slidably connected within the lifting groove 6. These plates are fixedly mounted on the outer wall of the rotating shaft 7. A trapezoidal extrusion plate 10 is slidably connected to the bottom inner wall of the lifting groove 6. The trapezoidal extrusion plate 10 cooperates with the trapezoidal lifting plates 9 and is threadedly connected to the first screw 11. When the trapezoidal extrusion plate 10 moves, it pushes the trapezoidal lifting plates 9 up or down, thereby driving the rotating shaft 7 and the rubber wheels 8 up and down. The trapezoidal extrusion plate 10 is threadedly connected to the first screw rod 11 , so when the first screw rod 11 rotates, the trapezoidal extrusion plate 10 can be driven to move.

[0052] Specifically, when it is necessary to adjust the position of the support bed board 5 for the patient's back, the first screw 11 is first rotated by the second screw 12. The first screw 11 drives the trapezoidal extrusion plate 10 to move and push the rotating shaft 7 and the rubber wheel 8 located on its outer wall to move upward. The multiple rubber wheels 8 on the multiple support bed boards 5 move upward synchronously to initially support the patient's back, avoiding friction damage to the patient's back when the support bed board 5 moves later. Then, the first threaded rod 4 is rotated to drive the multiple support bed boards 5 located on its outer wall to move synchronously, thereby adjusting the position of the support bed board 5 for the patient's back, avoiding long-term compression at the same position and the formation of pressure sores. When the support bed board 5 moves, the rubber wheel 8 can not only reduce the friction between it and the back, but also provide a slight massage to the back by rolling.

[0053] Reference Figure 6 and Figure 7A connecting plate 13 is provided on one side of the left bed board 2, and a protective structure is provided on one side of the connecting plate 13. The protective structure includes a gear 14 that rotates on one side of the connecting plate 13, and the gear 14 is fixedly sleeved on the outer wall of the first threaded rod 4. The connecting plate 13 is rotatably sleeved on the outer wall of the first threaded rod 4 and the second screw 12 and is located on one side of the bed frame 1. A sliding sleeve 15 is threadedly sleeved on the outer wall of the second screw 12, and a fixed rod 16 is slidably passed through the sliding sleeve 15, and one end of the fixed rod 16 is fixedly connected to one side of the connecting plate 13. A movable plate 17 is slidably connected to the side of the connecting plate 13 close to the sliding sleeve 15, and the movable plate 17 and the sliding sleeve 15 are rotatably connected by a connecting rod 18. A sliding rod 19 is slidably connected to the end of the movable plate 17 close to the gear 14, and a latch 21 is fixed to one end of the sliding rod 19, and the latch 21 is used to brake the gear 14. A spring 20 is abutted between the latching tooth 21 and the movable plate 17 via a spring seat. The spring 20 is sleeved on the outer wall of the slide bar 19 to make way for the movement of the latching tooth 21 .

[0054] Specifically, during operation, when the second lead screw 12 rotates to drive the rubber wheel 8 upward to support the back, the second lead screw 12 drives the sliding sleeve 15 to move away from the connecting plate 13. The sliding sleeve 15 drives the movable plate 17 and the latching teeth 21 to move away from the gear 14 via the connecting rod 18, thereby releasing the brake applied by the latching teeth 21 to the gear 14, facilitating the subsequent synchronous movement of the multiple support bed boards 5 by the first threaded rod 4. Conversely, when the second lead screw 12 moves in the opposite direction to store the rubber wheel 8 in the lifting slot 6, the cooperation between the sliding sleeve 15 and the connecting rod 18 drives the movable plate 17 and the latching teeth 21 to move toward the gear 14, which brakes the gear 14, thereby preventing the first threaded rod 4 from driving the support bed boards 5 to move when not needed, causing friction damage to the patient's back.

[0055] Reference Figure 2 and Figures 8-10 The body position adjuster also includes two U-shaped plates 23 fixed to the bottom of the bed frame 1. A third lead screw 30 and a first lead screw 24 are rotatably connected to each U-shaped plate 23. A rotating rod 28 is rotatably connected to the bottom of the bed frame 1 via a base. The outer wall of the rotating rod 28 is equipped with a first driving sprocket 29 and a second driving sprocket 34. A flip mechanism is provided within the two U-shaped plates 23 to drive the left and right bed boards 2 and 3 to flip.

[0056] Reference Figure 2 and Figures 8-10The flipping structure includes two first push plates 26 rotatably connected to the bottom of the left bed board 2, and two second push plates 32 rotatably connected to the bottom of the right bed board 3. In addition, the tops of the two U-shaped plates 23 are slidably connected to the first movable seat 25 and the second movable seat 31. The first movable seat 25 and the second movable seat 31 are respectively threadedly sleeved on the outer walls of the first screw 24 and the third screw 30. Specifically, the bottom end of the first push plate 26 is rotatably connected to the top of the first movable seat 25, and the bottom end of the second push plate 32 is rotatably connected to the top of the second movable seat 31. When the first movable seat 25 or the second movable seat 31 moves, they will drive the left bed board 2 or the right bed board 3 to flip through their respective first push plates 26 or second push plates 32. In order to synchronously drive the rotation of the first screw 24 and the third screw 30, the outer walls of the two first screws 24 are fixedly sleeved with a first sprocket 27, while the outer walls of the two third screws 30 are fixedly sleeved with a second sprocket 33. Here, the first driving sprocket 29 and the two first sprockets 27, as well as the second driving sprocket 34 and the two second sprockets 33, are all connected by chains. Therefore, when the rotating rod 28 rotates, it drives the two first lead screws 24 through the first driving sprocket 29, the first sprocket 27, and the chain, thereby driving the first movable seat 25 to move, thereby flipping the left bed board 2. Similarly, the rotating rod 28 can also drive the right bed board 3 to flip through the second driving sprocket 34, the second sprocket 33, and the chain.

[0057] Reference Figures 8-10 The rotating rod 28 is provided with a circular cavity 35, in which two movable disks 36 are slidably connected. The two movable disks 36 are fixedly connected by a connecting rod. A conical platform 37 is fixed to the side of each movable disk 36 facing away from each other. The rotating rod 28 is also provided with a locking structure for controlling the braking of the rotating rod 28 and the first driving sprocket 29 or the second driving sprocket 34. The configuration of these structures enables the body position adjuster to achieve more functions, such as flipping the left and right bed boards 2 and 3, to meet the needs of different patients.

[0058] Reference Figures 8-10 The locking structure includes a second threaded rod 42 threadedly connected to the rotating rod 28, one end of which extends to the outside of the rotating rod 28. The inner walls of the first and second driving sprockets 29, 34 are each provided with a plurality of pin grooves 41. In addition, an extension structure is provided within the circular cavity 35 to enable the rotating rod 28 to alternately engage with the first and second driving sprockets 29, 34 for braking.

[0059] Reference Figure 9 and Figure 10The extension structure includes multiple pins 40 that slide through the rotating rod 28 and engage with adjacent pin slots 41. To drive the pins 40 into or out of the pin slots 41, inclined surfaces are provided on one side of each pin slot 41, and these inclined surfaces can be squeezed into the adjacent conical platform 37. Furthermore, a fixing plate 39 is fixed to one side of each pin 40, and a tension spring 38 is fixed to the side of the fixing plate 39 away from the conical platform 37. These tension springs 38 are fixedly connected to the inner wall of the circular cavity 35. One end of the second threaded rod 42 is rotatably connected to the adjacent conical platform 37. The spring 20 is made of medical stainless steel with an elastic coefficient of 80-180N / m, a wire diameter of 0.8-1.2mm, and an outer diameter of 8-12mm. It is graded and matched according to the patient's weight (40-120kg), taking into account the braking force. The tension spring 38 is made of piano steel wire with an elastic coefficient of 150-280N / m, a wire diameter of 1.2-1.8mm, and an outer diameter of 10-15mm. The high elastic coefficient achieves rapid reset, ensuring the reliability and durability of the transmission mechanism.

[0060] Specifically, when the left bed board 2 needs to be flipped, the second threaded rod 42 can be rotated to drive the conical platform 37 to move outward. The conical platform 37 will squeeze the adjacent pin rod 40, causing it to enter the pin groove 41, thereby completing the braking between the rotating rod 28 and the first driving sprocket 29. Then, the rotating rod 28 can drive the first lead screw 24 to rotate through the cooperation of the first driving sprocket 29, the chain, and the first sprocket 27. The rotation of the first lead screw 24 will drive the first movable seat 25 to move, and then drive the left bed board 2 to rotate through the first push plate 26, completing the turning operation. Conversely, when the conical platform 37 moves in the opposite direction, the rotating rod 28 will brake between the second driving sprocket 34, thereby driving the third lead screw 30 to rotate, completing the flipping of the right bed board 3.

[0061] Reference Figure 8 Furthermore, to optimize transmission efficiency, the diameter of the first driving sprocket 29 is set to be larger than that of the first sprocket 27, while the diameter of the second driving sprocket 34 is also set to be larger than that of the second sprocket 33. Furthermore, the angles between the two chains and the first and second driving sprockets 29 and 34 are controlled to be less than 90° to ensure that the chains can successfully complete transmission operations.

[0062] Reference Figure 2 and Figure 6The bed frame 1 is constructed with two arc-shaped notches on one side. These notches allow one end of the two first threaded rods 4 to pass through and extend, thereby giving way to the first threaded rods 4 and allowing them to rotate and move smoothly. Similarly, an arc-shaped slot is designed on one side of the bed frame 1 to allow one end of the two second lead screws 12 to pass through and extend, thereby giving way to the second lead screws 12 and ensuring smooth operation of the second lead screws 12. For ease of operation, a handle 22 is fixed to one end of each of the first threaded rods 4 and the second lead screw 12, allowing the user to easily rotate and move these rods and lead screws by grasping the handle 22.

[0063] The pressure ulcer prevention nursing bed on the medical and health big data sharing platform not only includes the aforementioned position adjuster, but also features a control box at the bottom of the bed frame 1 and a display screen on one side. The control box houses a single-chip microcomputer, which is electrically connected to the display screen. Through the microcontroller, patient information can be transmitted to the medical and health big data sharing platform on the internet. Simultaneously, the big data sharing platform also transmits the patient's position information, which requires adjustment, to the display screen for display. This allows medical staff to conveniently adjust the patient's position based on the information displayed on the screen to meet their care needs.

[0064] Example 2: Reference Figure 11 and Figure 12 This embodiment is an improvement on Example 1: a left baffle 43 and a right baffle 45 are provided on either side of the bed frame 1. The left and right baffles 43 and 45 are connected to the bed frame 1 via a sliding connection, allowing for flexible up and down movement. Two first pull cords 44 are fixed to one side of the left baffle 43. One end of each of these first pull cords 44 passes through a corresponding U-shaped plate 23 and is fixedly connected to the second movable base 31. Similarly, two second pull cords 46 are fixed to one side of the right baffle 45. One end of each of these second pull cords 46 also passes through a corresponding U-shaped plate 23 and is fixedly connected to the first movable base 25.

[0065] When the left bed board 2 flips, the first movable base 25 connected to it moves outward. This movement simultaneously pulls the second pull cord 46, which in turn moves the right baffle 45 upward. This way, the right baffle 45 shields the side of the bed frame 1 near the right bed board 3, effectively preventing the patient from rolling off the right bed board 3 when the left bed board 2 flips. Similarly, when the right bed board 3 flips, the second movable base 31 connected to it pulls the left baffle 43 upward via the first pull cord 44, protecting the patient from rolling off the left bed board 2.

[0066] The method for using the anti-pressure ulcer nursing bed on the medical health big data sharing platform includes the following steps:

[0067] S1. The patient's information is transmitted to the medical health big data sharing platform on the Internet through the single-chip microcomputer, and the big data sharing platform displays the patient's body position information that needs to be adjusted on the display screen through the single-chip microcomputer, so that medical staff can adjust the patient's body position.

[0068] S2. When it is necessary to adjust the support of the support bed board 5 for the patient's back position to relieve the pressure sores caused by long-term pressure on the skin, the first screw 11 is first driven to rotate by the second screw 12. The first screw 11 drives the trapezoidal extrusion plate 10 to move and pushes the rotating shaft 7 and the rubber wheel 8 located on its outer wall to move upward. The multiple rubber wheels 8 on the multiple support bed boards 5 move upward synchronously to provide preliminary support for the patient's back, thereby avoiding friction damage to the patient's back when the support bed board 5 moves later; then, the first threaded rod 4 drives the multiple support bed boards 5 located on its outer wall to move synchronously, adjust the position of the support bed board 5 for the patient's back, thereby avoiding the pressure sores caused by long-term compression at the same position. When the support bed board 5 moves, the rubber wheels 8 not only reduce the friction between it and the back, but also can massage the back through the rubber wheels 8;

[0069] S3. When the second lead screw 12 rotates to drive the rubber wheel 8 to move upward to support the back, the second lead screw 12 drives the sliding sleeve 15 to move in the direction away from the connecting plate 13. The sliding sleeve 15 drives the movable plate 17 and the latch 21 to move to the side away from the gear 14 through the connecting rod 18, releasing the brake of the latch 21 on the gear 14, so that the first threaded rod 4 can drive multiple supporting bed boards 5 to move synchronously in the later stage; on the contrary, after the second lead screw 12 moves in the opposite direction and the rubber wheel 8 is stored in the lifting groove 6, the cooperation of the sliding sleeve 15 and the connecting rod 18 drives the movable plate 17 and the latch 21 to move in the direction of the gear 14, and the latch 21 brakes the gear 14, so as to avoid friction damage to the patient's back caused by the first threaded rod 4 driving the supporting bed board 5 to move;

[0070] S4. When the patient needs to turn over and lie on his side in the direction of the right bed board 3, the second threaded rod 42 is rotated to drive the conical platform 37 to move outward, and the conical platform 37 squeezes the adjacent pin rod 40 into the pin groove 41, completing the braking between the rotating rod 28 and the first driving sprocket 29. Then, the rotating rod 28 drives the first lead screw 24 to rotate through the cooperation of the first driving sprocket 29, the chain and the first sprocket 27, and the first lead screw 24 drives the left bed board 2 to rotate through the first push plate 26 to complete the turning operation; conversely, when the conical platform 37 moves in the opposite direction, the braking between the rotating rod 28 and the second driving sprocket 34 can drive the third lead screw 30 to rotate, completing the turning of the right bed board 3. The turning of the left bed board 2 or the right bed board 3 can be completed by the movement of the conical platform 37 and the rotation of the rotating rod 28. The operation is simple and does not require the use of too many driving structures, which greatly reduces the production cost.

[0071] S5. When the left bed board 2 is flipped, the first movable seat 25 moves outward, and at the same time, the first movable seat 25 pulls the right baffle 45 upward through the second pull rope 46. The right baffle 45 blocks the side of the bed frame 1 close to the right bed board 3 to prevent the patient from rolling off the right bed board 3 when the left bed board 2 is flipped. Conversely, when the right bed board 3 is flipped, the second movable seat 31 pulls the left baffle 43 upward through the first pull rope 44 to protect the patient.
