Description

Technical Field

[0001] The invention relates to the technical field of turning devices, and in particular to a turning device suitable for critical care. Background Art

[0002] A turning device is a device used to help people who are bedridden for a long time, patients with spinal cord injuries, or those recovering from surgery change their body posture. It can relieve the discomfort caused by maintaining the same posture for a long time, prevent the occurrence of pressure sores, improve blood circulation, and maintain normal physiological functions. The use of a turning device can significantly reduce the burden on nursing staff and improve nursing efficiency. The turning device or appliance that realizes the turning action is widely used in the medical field.

[0003] At present, most turning beds that assist patients in changing their body posture adopt a structure that allows unilateral turning from the middle of the bed. Due to the shape and structural characteristics of the human body, when turning along the central axis, the movement speed and path of different parts of the body are difficult to be completely synchronized. The upper body changes position faster than the lower body when turning, which will generate shear force between the skin and the bed surface. This shear force will increase the risk of pressure sores. Summary of the invention

[0032] The present invention will be further described below in conjunction with the embodiments.

[0033] Example:

[0034] See also Figure 1-Figure 8 The present invention provides a technical solution: a turning device suitable for critical care, comprising:

[0035] The bed body 1 comprises a bed frame 11, the inner wall of the bed frame 11 is fixedly connected with a fixing frame 12, and the lower surface of the bed frame 11 is fixedly connected with a supporting leg 13, and the upper surface of the fixing frame 12 is provided with a folding mechanism 2 that can be used to assist the patient to turn over;

[0036] The folding mechanism 2 includes a middle plate 21, which is designed in an isosceles trapezoidal shape, which is more in line with the shape of the human body structure and is conducive to turning over the whole body at a uniform speed. The middle plate 21 is rotatably connected to the side plates 23 through a rotating rod 22 arranged on its outer surface. Two side plates 23 are arranged and are symmetrically distributed with the middle plate 21 as the center. The outer surface of the fixing frame 12 is provided with a driving component 24 that can be used to adjust the rotation angle of the middle plate 21;

[0037] Among them, the side plate 23 includes an upper plate 231 and a lower plate 232. The lower surface of the upper plate 231 fits with the upper surface of the lower plate 232, and one side of the upper plate 231 and the lower plate 232 are rotatably connected to the circumferential outer surface of the rotating rod 22. The upper plate 231 and the middle plate 21 are respectively provided with side notches and middle notches, and the side notches are provided with linkage parts 25.

[0038] The driving assembly 24 includes a cylinder 241, which is fixedly connected to the outer surface of the bed frame 11 via a bracket arranged at its bottom end. The output end of the cylinder 241 is rotatably connected to a connecting frame 242. The connecting frame 242 is fixedly connected to a rotating rod 243 on a side away from the cylinder 241. The outer end of the rotating rod 243 is rotatably connected to the outer surface of the fixed frame 12. The circumferential outer surface of the rotating rod 243 is fixedly connected to a connecting rod 244. The end of the connecting rod 244 away from the rotating rod 243 is rotatably connected to a connecting block 245 via an axial rod.

[0039] The upper surface of the connection block 245 is designed as an arc surface, and the lower surface of the middle plate 21 is fixedly connected with a support block 246 that fits the upper surface of the connection block 245 .

[0040] A headboard 111 is fixedly connected to the upper surface of the bed frame 11, and a footboard 112 is fixedly connected to the side of the upper surface of the bed frame 11 away from the headboard 111. The headboard 111 fits with the circumferential outer surface of the rotating rod 22 through an arc groove 1111 provided therein. An accommodating cavity 1112 connected to the arc groove 1111 is provided inside the headboard 111, and an arc groove 1111 and an accommodating cavity 1112 are also provided inside the footboard 112. An adjusting member 26 is provided inside the accommodating cavity 1112. The internal structures of the headboard 111 and the footboard 112 are designed using the same principle.

[0041] The adjusting member 26 includes a tooth block 261, one side of which is fixedly connected to the outer end of the rotating rod 22. The accommodating chamber 1112 is rotatably connected to the gear 262 through a support frame arranged at the bottom of its inner wall. The interior of the accommodating chamber 1112 is slidably connected to a tooth rod 263, and the outer surface of the tooth rod 263 is fixedly connected to a limit block 264 that can be used to limit the position of the rotating rod 22. The tooth rod 263 and the tooth block 261 are staggered front and back. The adjusting member 26 can ensure the stability of the folding mechanism 2 when it is flipped.

[0042] The linkage part 25 includes a retractable rod 251, which is rotatably connected to the bottom of the inner wall of the side slot by an axle pin arranged at its bottom end. The end of the retractable rod 251 away from the upper plate 231 is rotatably connected to a threaded rod 252, and the inside of the middle slot is rotatably connected to a rotating rod 253. The circumferential outer surface of the rotating rod 253 is sleeved with a threaded sleeve 254, which is engaged with the threaded sleeve 254 and the threaded rod 252, so that the upper plate 231 and the middle plate 21 can be adjusted to an angle and be in a relatively fixed state, and can be linked to cooperate to complete the patient's turning over.

[0043] A handle 2311 is fixedly connected to the upper surface of the upper plate 231, and a head protection part 27 is fixedly connected to the upper surface of the middle plate 21. The head protection part 27 adopts a C-shaped design, and the two sides and the middle of the head protection part 27 are designed to be inclined. After the folding mechanism 2 is flipped, the side of the head protection part 27 can fit with the upper surface of the upper plate 231 in the flipping direction. At the same time, the outer surface of the head protection part 27 adopts an arc transition to ensure that the cervical spine will not be damaged due to sudden changes in the head position or improper force during turning over and changing posture.

[0044] Because of the limited physical activity of critically ill patients, maintaining a posture for a long time will cause continuous pressure on local tissues of the body. Under continuous pressure on the skin and subcutaneous tissue of the human body, blood circulation will be hindered. By turning over regularly, the pressure points of various parts of the body can be changed, so that the originally compressed parts can be temporarily relieved and blood circulation can be restored. It is generally recommended to turn critically ill patients over once in a while, which can effectively reduce the occurrence of pressure sores.

[0045] The process of turning the patient over:

[0046] The middle plate 21 and the side plates 23 are provided with a plurality of ventilation holes to help the patient dissipate heat better and reduce the occurrence of pressure sores. A thin pad that matches the device is placed on the upper surface of the folding mechanism 2 without affecting the normal use function. In the initial state, the patient lies flat on the upper surface of the middle plate 21, the connecting line from the patient's shoulder to the hip fits the bevel of the side of the middle plate 21, and the head rests on the head protection member 27. There are two groups of driving components 24, which are symmetrically distributed around the middle plate 21, and are used to turn the patient over in different directions. When the patient maintains the same posture for a period of time, the drive assembly 24 on one side is started through the external drive panel or the timing system to start the cylinder 241 on this side. After the cylinder 241 is started, its output end extends toward the middle plate 21, driving the connecting frame 242 and the rotating rod 243 to rotate upward synchronously inside the fixed frame 12, and the connecting rod 244 fixedly connected to the circumferential outer surface of the rotating rod 243 also rotates synchronously, and the end of the connecting rod 244 away from the rotating rod 243 is rotatably connected to the connecting block 245, the upper surface of the connecting block 245 adopts a convex surface design, and the lower surface of the middle plate 21 is fixedly connected to the supporting block 246, the lower surface of the supporting block 246 adopts a concave surface design, which fits the convex surface of the connecting block 245, and when the connecting rod 244 rotates upward, the convex surface of the connecting block 245 supports the concave surface of the supporting block 246, driving the middle plate 21 to rotate with the left rotating rod 22 as the axis.

[0047] Since the patient lies flat on the upper surface of the middle plate 21 and has a certain weight, when the right cylinder 241 is started, the middle plate 21 will be lifted upward from the position of the right support block 246, and the right rotating rod 22 will follow the middle plate 21 and rotate upward with the left rotating rod 22 as the axis. The right rotating rod 22 will move along the path of the arc groove 1111 inside the headboard 111 and the footboard 112. The footboard 112 and the headboard 111 are proportionally scaled, and both are provided with adjustment parts 26. The inclination of the arc groove 1111 inside the footboard 112 and the headboard 111 is the same to ensure the overall smooth rotation of the middle plate 21. The two ends of the rotating rod 22 are fixedly connected with tooth blocks 261. When the rotating rod 22 is lifted upward, the tooth blocks 261 at both ends thereof tilt upward synchronously. During this process, the tooth block 261 will mesh with the gear 262. At the same time, a tooth rod 263 meshing with the gear 262 is also provided above the gear 262. The gear 262 is relatively thick, and the tooth block 261 and the tooth rod 263 are staggered front and back to avoid collision. When the tooth block 261 moves upward, it will drive the gear 262 to rotate counterclockwise. The tooth rod 263 provided above the gear 262 slides to the left under the action of the gear 262. The tooth rod 263 as a whole is in the accommodating cavity. 1112 fits inside and slides smoothly, and the limit block 264 fixedly connected to the left side of the gear rod 263 slides to the left along with the gear rod 263 until the limit block 264 on the left slides to the upper surface of the left rotating rod 22, fixing the left rotating rod 22 in its initial position and keeping it motionless, thereby increasing the stability during the turning over process and preventing the middle plate 21, the side plate 23 and the rotating rod 22 from being lifted upward as a whole under the action of the cylinder 241 and separated from the fixing frame 12, thereby improving safety.

[0048] The two ends of the left rotating rod 22 are respectively fixed to the bottom of the arc groove 1111 in the headboard 111 and the bottom of the arc groove 1111 in the footboard 112, while the right rotating rod 22 moves upward along the path of the arc groove 1111 inside the headboard 111 and the footboard 112. At this time, the middle plate 21 and the right side plate 23 as a whole slowly turn to the left along the left rotating rod 22 as the axis. A limiting device is set under the middle plate 21 and the lower plate 232, so that when the middle plate 21 rotates to the left, the lower plate 232 on the right side will move with it, and when the middle plate 21 rotates to the right, the lower plate 232 on the left side will move with it, and they are in a relatively static state.

[0049] At the same time, the head protection part 27 fixed on the upper surface of the middle plate 21 will rotate with the middle plate 21. Since the middle plate 21 adopts an isosceles trapezoidal design that is wider on the side close to the headboard 111 and narrower on the side close to the footboard 112, it fits the shape of the human body. The patient can turn over from the shoulder to the hip, which is closer to the natural turning over movement of the human body and more in line with the natural turning over habit. After reaching the required turning over angle, the cylinder 241 stops running, and the middle plate 21 maintains this angle and is fixed to the side plate 23 on the left. The left side of the head protection piece 27 is now in contact with the upper surface of the left side plate 23. At this time, the pressure center of the patient is transferred from the back to one side of the body. The patient's head contacts the middle upper surface of the head protection piece 27 from the back of the head in the initial state, and after turning over, the cheek contacts the left part of the head protection piece 27. This can well protect the patient's cervical spine from injury and avoid being pulled during the turning process, which is more in line with the natural turning over effect. After turning over, the patient is in a tilted state on the bed 1, and the degree of body inclination is parallel to the rotating rod 22 on the left side of the middle plate 21.

[0050] After turning over for a period of time, the human body needs to be restored to a lying position, and then turned in the opposite direction. The cylinder 241 is controlled to return to the initial state through an external drive panel or a timing system, and the output end of the cylinder 241 slowly retracts, and the connecting frame 242 gradually falls back from the inclined upward state to the horizontal state. During this period, the rotating rod 243 and the connecting rod 244 fixedly connected to the connecting frame 242 rotate synchronously, wherein the rotating rod 243 is rotatably connected in the fixed frame 12. When the folding mechanism 2 is in operation, the connecting rod 244 and the connecting frame 242 on the same side are always in the same motion state and remain relatively static. The end of the connecting rod 244 away from the rotating rod 243 follows the cylinder 241 to fall back until it returns to its initial contracted state, and the convex surface of the connecting block 245 fits tightly with the concave surface of the support block 246, and the support block 246 is smoothly restored to the initial position. At the same time, the rotating rod 22 on the right side of the middle plate 21 moves with the middle plate 21, and gradually moves to the bottom of the arc groove 1111 under the limitation of the arc groove 1111. When the tooth blocks 261 at both ends of the rotating rod 22 enter the accommodating chamber 1112, the teeth on the left side of the tooth block 261 will mesh with the teeth of the gear 262, driving the gear 262 to rotate clockwise. After it rotates clockwise, the gear rod 263 in the gear 262 and meshing with it recovers to the right side, and the limiting block 264 fixedly connected to the side thereof slides smoothly to the right synchronously, and the left rotating rod 22 is no longer limited. Until the tooth block 261 reaches the bottom of the accommodating chamber 1112, the rotating rod 22 also recovers to its initial state, at which time the middle plate 21 and the side plate 23 on the right side recover to their initial state, and the whole is in a horizontal state.

[0051] After turning over, the patient and the bed 1 are transformed into a vertical state, the body lies flat on the upper surface of the middle plate 21, the line from the left shoulder to the buttocks is nearly coincident with the left rotating rod 22, and the line from the right shoulder to the buttocks is nearly coincident with the right rotating rod 22. The pressure center of gravity of the patient is transferred from one side of the body to the back, and the patient's head contacts the left part of the head protection member 27 from the cheek. After turning over to lie flat, the back of the head contacts the middle upper surface of the head protection member 27. After the patient maintains this posture and lies flat for a period of time, the cylinder 241 in the other side drive assembly 24 is controlled by the external drive panel or the timing system to start, and the left side plate 23 and the middle plate 21 are turned to the right to help the patient turn over to the right. Since the left and right structures are the same, this process is the same as the above-mentioned turning over to the left, and the process is repeated regularly to assist the patient in changing his body posture.

[0052] Turning process for special patients:

[0053] The patient lies flat on the upper surface of the middle plate 21 and does not contact the upper plate 231. In the initial state, the linkage parts 25 are all in a retracted state and hidden inside the middle plate 21 and the upper plate 231, which does not affect normal use and does not cause harm to the human body. After checking that the patient's condition meets the conditions for turning over, the staff rotates and pulls the retracted rotating rod 253 in the middle plate 21 from the inside of the middle notch so that the rotating rod 253 and the middle plate 21 are in a vertical state, rotates and pulls the retracted retracted rod 251 in the left upper plate 231 from the inside of the side notch so that the retracted retracted rod 251 and the upper plate 231 remain in a vertical state, pulls the handle 2311 on the upper surface of the upper plate 231, and turns the left upper plate 231 toward the middle plate 21 along the rotating rod 22 on its side, and rotates the threaded rod 252 above the retracted rod 251 to a certain angle, and moves the threaded sleeve 254 above the retracted rod 253 closer to the threaded rod 252.

[0054] When the upper surface of the threaded rod 252 is aligned with the top of the threaded sleeve 254, the threaded sleeve 254 is rotated, and the threads on the outer surface of the threaded rod 252 are meshed with the threads on the inner wall of the threaded sleeve 254. By changing the depth of the threaded sleeve 254 and the threaded rod 252, the upper plate 231 is flipped to the desired position, so that the threaded rod 252 and the rotating rod 253 are fixedly connected. The linkage parts 25 are provided with two groups, each group includes two, and are symmetrically distributed with the middle plate 21 as the center, one group is located near the headboard 111, and the other group is located near the footboard 112. When the threaded rods 252 and the rotating rods 253 in the two groups of linkage parts 25 are fixed, the upper plate 231 is flipped toward the patient who is lying flat, and at this time, the upper surface of the upper plate 231 is in contact with the side of the head protection member 27, and the upper plate 231 and the middle plate 21 are fixed, forming an angle between them, and the patient is slightly clamped.

[0055] After the clamping is completed, the drive assembly 24 in the opposite direction is controlled by the external drive panel, that is, the cylinder 241 in the right drive assembly 24 is started, so that the middle plate 21 rotates along the left rotating rod 22 as the axis. During this process, the right side plate 23 and the middle plate 21 always maintain the same horizontal plane, and the left side plate 23 and the middle plate 21 still maintain a certain angle and rotate stably until the patient is turned over. At this time, the patient's pressure center of gravity is transferred from the back to one side of the body. The patient's head contacts the middle upper surface of the head protection member 27 from the back of the head in the initial state, and the cheek contacts the left part of the head protection member 27 after turning over. The head protection member 27 is fixed with a back plate near the side of the headboard 111, which reduces the possibility of hair getting stuck in the arc groove 1111. In the process of assisting turning over, by clamping the patient and rotating, the patient's body can be effectively prevented from slipping when turning over. Especially for patients who are unconscious, weak or large in size, they may not be able to cooperate with the turning over action independently. This clamping method can ensure that the patient's body is always in a safe position, avoiding the patient from falling off the bed and getting injured due to turning over. The staff can turn the patient from the supine position to the lateral position and keep it at a specific angle. During this process, the patient's body is stably clamped, reducing the shaking of the body, reducing the patient's discomfort symptoms such as dizziness and nausea, and improving comfort.

[0056] After the patient maintains this posture for a period of time, the patient needs to be turned over and restored. Through the external drive panel or timing system, the middle plate 21 and the right side plate 23 are restored to the initial state by controlling the cylinder 241, and the human body is restored to a lying position. Then, by rotating the threaded sleeve 254, the threaded rod 252 is separated from the rotating rod 253, and the upper plate 231 is restored to a horizontal state by pulling the handle 2311 on the upper surface of the upper plate 231. Finally, the rotating rod 253 and the retracting rod 251 are respectively rotated to the inside of the middle plate 21 and the side plate 23, so that they are in a retracted state. After maintaining the lying position for a period of time, the above actions can be repeated to turn the patient in the opposite direction.

[0057] For patients who have undergone spinal injuries, pelvic surgery, or major abdominal surgery, the threaded sleeves 254 on both sides can be connected and fixed to the threaded rods 252 at the same time, so that the side panels 23 on both sides form a certain angle with the middle panel 21, and then the patient can be turned over. This process can ensure the stability of the spine during the turning process. This turning method can make the body weight more evenly distributed on the folding mechanism 2 during the turning process. The movement of the body will not cause the displacement of the pelvic fracture end or the loosening of the hip joint prosthesis, ensuring the stability of these key parts, which is conducive to fracture healing and joint function recovery. It can also avoid compression or traction of the nerves due to abnormal activities of the spine, thereby reducing the risk of nerve damage.

[0058] In summary, turning the patient over has the following advantages:

[0059] Advantage 1: The middle plate 21 adopts an isosceles trapezoidal design that is wide in the front and narrow in the back, which fits the side of the human body. From the shoulder to the hip, the folding mechanism 2 flips in different directions along the two oblique sides of the middle plate 21. When flipping, the patient's side fits the oblique sides of the middle plate 21, and the whole body can rotate with the natural curve of the body. The spine can maintain a relatively stable physiological curvature in this process, and there will be no excessive local force on the spine that may occur when the central axis is flipped, which is conducive to maintaining the spine in a relatively comfortable and safe state.

[0060] Advantage 2: The hypotenuse of the middle plate 21 coincides with the line from the shoulder to the buttocks of the human body. During the turning process, the middle plate 21 rotates with the rotating rod 22 of its hypotenuse, which can be understood as turning over naturally along the line from the shoulder to the buttocks of the human body, and the movement of various parts of the body is more coordinated. In this process, the skin and subcutaneous tissue are subjected to less shear force. Compared with the turning of the central axis, the turning of the central axis may produce a larger shear force due to the asynchronous movement of the upper and lower parts of the body (for example, the upper body turns first, and the lower body turns later), which is easy to cause skin damage and pressure sores. The rotating rod 22 is parallel to the line from the shoulder to the buttocks, the inclination angle of the body is the same, and the movement speed and path of different parts of the body are the same. Turning with the rotating rod 22 as the axis effectively prevents the occurrence of pressure sores by reducing shear force and improves the health of the patient's skin. Turning from the shoulder to the buttocks is closer to the natural turning action of the human body and more in line with the natural turning habit. The patient will feel more comfortable in this process, just like turning over in a natural sleeping state. This natural way of turning over can reduce patients' resistance to turning over and improve their cooperation with nursing.

[0061] Advantage three: the folding mechanism 2 is symmetrically designed, the rotating rod 22 of the bed body 1 is fixed in position, and the movement trajectories of the middle plate 21 and the side plate 23 during the flipping process are completely symmetrical. Each time the bed is flipped to the same angle and the middle plate 21 is turned to a horizontal state, the patient will return to its original position without having to move the patient again, thus avoiding unnecessary friction and collision of the patient, reducing the physical exertion of nursing staff, improving work efficiency, and at the same time, reducing the risk of inaccurate data or equipment failure due to equipment displacement.

[0062] Advantage 4: When the middle plate 21 is flipped along one of the rotating rods 22, the gear 262 can be meshed and rotated through the upward movement of the rotating rod 22 on the other side and the tooth block 261. At the same time, the tooth rod 263 meshing with the upper part of the gear 262 moves toward the rotating rod 22 to complete the fixation of the rotating rod 22, thereby ensuring the stability of the turning structure and avoiding safety hazards such as patients falling and equipment damage.

[0063] Advantage 5: For patients who are unconscious, weak or large in size, the upper plate 231 and the middle plate 21 are fixed by the linkage 25 to form an angle to clamp the patient, effectively preventing the patient from slipping when turning over, ensuring safety. For patients with spinal injuries, pelvic surgery and major abdominal surgery, the upper plate 231 and the middle plate 21 on both sides of the side plates 23 can be fixed at the same time to ensure the stability of the spine during the turning process, which is conducive to fracture healing and joint function recovery, and reduces the risk of nerve damage.

[0064] Advantage 6: The head protection part 27 can adapt to different turning angles. The head protection part 27 is always closely connected with the patient's head, and changes the contact position with the head as the middle plate 21 rotates, ensuring that the cervical spine will not be damaged due to sudden changes in the head position or improper force during turning over and posture changes.
