[0034] First embodiment

[0035] See also Figure 1 to Figure 6 The present invention provides a patient care turning device, including a support frame 101, a bed board 102, a plurality of bandages 103, two connecting rods 104, two L-shaped guide rails 105, and two driving units 106. The two L-shaped guide rails 105 are fixed on both sides of the support frame 101, and the two connecting rods 104 are respectively slidably set on the two L-shaped guide rails 105. The two driving units 106 are respectively connected to the two connecting rods 104 to drive the connecting rods 104 to slide on the L-shaped guide rails 105. The plurality of bandages 103 are connected to the two connecting rods 104 and are located on the bed board 102.

[0036] In this embodiment, the support frame 101 serves as the basic structure of the entire turning device, and the support frame 101 ensures the stability and safety of all components. It is usually made of high-strength materials to withstand the weight of patients of different weights.

[0037] The bed board 102 is installed on the support frame 101 to provide a flat and comfortable lying surface for the patient. The design of the bed board 102 needs to take into account ergonomic principles to improve the comfort of the patient. Multiple bandages 103 are one of the key components for turning the patient over. One end of them is connected to two connecting rods 104, and the other end is placed on the bed board 102. The position can be adjusted as needed to accommodate patients with different body shapes or turning needs. The material of the bandage 103 should be soft and have sufficient strength to ensure safe and effective movement of the patient.

[0038] Each connecting rod 104 is installed in an L-shaped guide rail 105 and can slide up and down along the guide rail. This design allows the connecting rod 104 to smoothly drive the bandage 103 and the patient thereon to complete the turning action when the drive unit 106 is working.

[0039] Two L-shaped guide rails 105 are fixed on both sides of the support frame 101, providing a movement track for the connecting rod 104. The L-shaped design not only increases the stability of the structure.

[0040] Each driving unit 106 is responsible for controlling the connecting rod 104 on the corresponding side. By precisely controlling the motor or other power source, the driving unit 106 can move the connecting rod 104 at a preset speed and direction, thereby driving the bandage 103 and the patient to turn over. In addition, in order to ensure the safety of operation, the driving unit 106 is usually integrated with sensors and control systems to monitor the device status and respond in time.

[0041] In summary, this patient care turning device can automatically turn the patient over, allowing medical staff to maintain the patient's position and then perform nursing actions after the patient turns over to the corresponding position, thereby reducing the burden on medical staff and providing patients with more humane and efficient nursing services.

[0042] The bandage 103 includes a bandage body 107 and two connecting buckles 108 . The two connecting buckles 108 are fixed on both sides of the bandage body 107 and are used to be connected to the connecting rod 104 .

[0043] The bandage 103 is composed of a bandage body 107 and two connecting buckles 108. The two connecting buckles 108 are fixed on both sides of the bandage body 107 so as to be connected to the connecting rod 104 to achieve effective support for the patient during turning over.

[0044] The connecting buckle 108 includes a connecting block 109, a locking rod 110 and a second spring 111. The connecting block 109 is slidably set on the connecting rod 104, and the locking rod 110 is slidably set on the connecting block 109. The second spring 111 is used to support the locking rod 110. A plurality of connecting grooves are set on the connecting block 109 corresponding to the locking rod 110.

[0045] The connecting block 109 is slidably arranged on the connecting rod 104, allowing the position of the bandage 103 to be flexibly adjusted according to the specific position of the patient. This not only improves the flexibility of use, but also increases the comfort of the patient when turning over.

[0046] The locking rod 110 is also mounted on the connecting block 109 in a sliding manner, and its main function is to lock the bandage 103 at a specific position to ensure that the bandage 103 does not accidentally slip off during the turning process. The locking mechanism of the locking rod 110 is achieved by cooperating with multiple connecting grooves on the connecting block 109.

[0047] The second spring 111 is installed between the locking rod 110 and the connecting block 109 to provide a force for the locking rod 110 to pop out. When the bandage 103 needs to be fixed at a certain position, the locking rod 110 only needs to be gently pulled up to align it with the connecting groove; after releasing, the locking rod 110 will be automatically clamped under the action of the second spring 111 to form a stable connection.

[0048] Matching marks are provided on the corresponding connecting grooves of the two connecting rods 104 .

[0049] Matching Marks In order to facilitate quick and accurate adjustment of the position of the bandage 103, matching marks are provided on the corresponding connecting grooves of the two connecting rods 104. This design simplifies the operation process and reduces the risk caused by misoperation.

[0050] The connecting rod 104 has a limit platform 112, which is located on a side close to the L-shaped guide rail 105. A limit nut 113 is threadedly connected to the limit platform 112, and the limit nut 113 cooperates with the limit platform 112 to prevent the connecting rod 104 from jumping longitudinally relative to the L-shaped guide rail 105.

[0051] Limiting platform 112 and limiting nut 113: In order to prevent the connecting rod 104 from unnecessary longitudinal movement (i.e. horizontal jumping) on ​​the L-shaped guide rail 105, a limiting platform 112 is provided on the side of the connecting rod 104 close to the L-shaped guide rail 105. A limiting nut 113 is threadedly connected to the limiting platform 112. The nut and the limiting platform 112 are used together to effectively limit the degree of freedom of the connecting rod 104 and ensure that it slides smoothly only along the predetermined path. This design not only enhances the stability of the system, but also extends the service life of the equipment.

[0052] The L-shaped guide rail 105 includes an L-shaped guide rail body 114 , a rotating belt 115 and a supporting roller 116 . The supporting roller 116 is rotatably disposed at one horizontal end of the L-shaped guide rail body 114 , and the rotating belt 115 is rotatably disposed on the supporting roller 116 .

[0053] The L-shaped guide rail body 114 serves as the skeleton of the entire system. The L-shaped guide rail body 114 not only provides a mounting base for other components, but also defines the movement path of the connecting rod 104. Its unique L-shaped design not only ensures sufficient support force, but also allows the connecting rod 104 to move freely in both vertical and parallel directions to meet different turning needs.

[0054] The support roller 116 installed at the horizontal end of the L-shaped guide rail body 114 is used to support the rotating belt 115, so that the connecting rod 104 in the horizontal direction can be better reset under the action of the patient's gravity. During resetting, the rotating belt 115 can be driven to rotate by friction, so that the connecting rod 104 can be easily moved to the vertical groove of the L-shaped guide rail body 114 and then easily moved downward.

[0055] The driving unit 106 includes a connecting rope 117, a winding mechanism 118 and a supporting pulley 119. The supporting pulley 119 is rotatably arranged on the L-shaped guide rail body 114. The winding mechanism 118 is fixed on one side of the supporting pulley 119. One end of the connecting rope 117 is connected to the connecting rod 104, and the other end of the connecting rope 117 is connected to the winding mechanism 118.

[0056] The connecting rope 117 is a bridge between the driving unit 106 and the connecting rod 104, one end of which is fixed on the connecting rod 104, and the other end is connected to the winding mechanism 118. The expansion and contraction of the connecting rope 117 can be controlled by the rotation of the winding mechanism 118, thereby driving the connecting rod 104 to move along the L-shaped guide rail 105.

[0057] The winding mechanism 118 fixed to one side of the support pulley 119 is the core component of the drive unit 106. It is usually driven by a motor and can automatically retract and release the connecting rope 117 according to the set program to achieve accurate positioning of the connecting rod 104. The performance of the winding mechanism 118 directly affects the smoothness and accuracy of the turning action. The support pulley 119 is installed on the L-shaped guide rail body 114 to provide guidance and support for the connecting rope 117. Its existence helps to reduce the direct friction between the connecting rope 117 and the L-shaped guide rail 105, and prolongs the service life of the connecting rope 117.

[0058] The driving unit 106 further includes a return spring 120 , and the return spring 120 is disposed on one side of the rotating belt 115 .

[0059] The return spring 120 disposed on one side of the rotating belt 115 is used to assist the connecting rod 104 to return to the initial position. When the driving unit 106 stops working, the return spring 120 will automatically pull back the connecting rope 117, prompting the connecting rod 104 to return to the starting point. This design not only simplifies the operation steps, but also improves the automation of the system.

[0060] The patient care turning device further comprises two guard plates 121 , and the two guard plates 121 are rotatably arranged on both sides of the bed board 102 .

[0061] The guard plate 121 includes a guard plate body 122, a clamping rod 123, a handle 124, an auxiliary support rod 125 and a buffer spring 126. The clamping rod 123 is rotatably set on the guard plate body 122, and the handle 124 is fixed on the clamping rod 123. A sliding groove is opened on the side of the support frame 101 close to the guard plate body 122. One end of the auxiliary support rod 125 is rotatably connected to the guard plate body 122, and the other end of the auxiliary support rod 125 is set in the sliding groove. The buffer spring 126 is set in the sliding groove.

[0062] The guard body 122 is the main component of the guard 121, and is usually made of a light but strong material, which can ensure strength and reduce overall weight. The design of the guard body 122 takes ergonomic principles into consideration, and the shape and size are suitable for patients of different body shapes.

[0063] The clamping rod 123 is rotatably arranged on the guard plate body 122, and is mainly used to fix the position of the guard plate 121. When the guard plate 121 is adjusted to a suitable angle, it can be locked by the clamping rod 123 to prevent accidental movement during the turning over process. A handle 124 is also fixed on the clamping rod 123 for user convenience.

[0064] The handle 124 is fixed on the clamp rod 123, providing a convenient means of operation for medical staff and patients. Through the handle 124, the angle of the guard plate 121 can be easily adjusted, or the guard plate 121 can be folded up when it is not needed to save space.

[0065] One end of the auxiliary support rod 125 is rotatably connected to the guard plate body 122, and the other end is arranged in a slide groove on the support frame 101. This design allows the guard plate 121 to remain stable when placed horizontally to provide more horizontal support, thereby increasing the flexibility and application range of the guard plate 121.

[0066] The buffer spring 126 is disposed in the slide groove and is located at the other end of the auxiliary support rod 125. Its main function is to provide a buffering effect when the guard plate 121 adjusts its angle, so as to prevent the guard plate 121 or the support frame 101 from being damaged due to a sudden impact. In addition, the buffer spring 126 can also slowly release energy when the guard plate 121 is lowered, so that the guard plate 121 returns to its original position smoothly, thereby increasing the safety and comfort of operation.

[0067] The patient care turning device also includes a control module, which includes a bandage adjustment unit 128, a lifting control unit 129 and a locking unit 130. The bandage adjustment unit 128 is used to control the lifting of the two driving units 106 to adjust the bandage 103 under the patient. The lifting control unit 129 is used to control the driving unit 106 to control the turning angle of the patient. The locking unit 130 is used to clamp the connecting rope 117 when the moving speed of the connecting rope 117 exceeds a preset value.

[0068] The bandage adjustment unit 128 is responsible for controlling the lifting and lowering actions of the two drive units 106 to accurately adjust the bandage 103 under the patient. By adjusting the position of the bandage 103, it can be ensured that the patient always remains comfortable and safe during the turning process. The bandage adjustment unit 128 drives the two connecting rods 104 to move up and down on the L-shaped guide rail 105 in succession through a motor or other power source. When the position of the bandage 103 needs to be adjusted, the control system will send a command to the motor to drive the connecting rod 104 to rise or fall. In this way, the bandage 103 can be accurately positioned at different parts of the patient's body to meet different turning needs.

[0069] The lifting control unit 129 is used to control the driving unit 106 and adjust the patient's turning angle. By accurately controlling the moving distance and speed of the connecting rod 104, turning actions at different angles can be achieved to meet the patient's personalized needs. The lifting control unit 129 sets different turning angles through programming. When a turning operation needs to be performed, the control system sends instructions to the driving unit 106 according to the preset parameters. After receiving the instruction, the driving unit 106 drives the connecting rod 104 to slide on the L-shaped guide rail 105 through the connecting rope 117, thereby adjusting the position of the bandage 103 to achieve the patient's turning.

[0070] The locking unit 130 is used to clamp the connecting rope 117 when the moving speed of the connecting rope 117 exceeds a preset value to prevent the patient from being injured due to an accident. The locking unit 130 has a built-in speed sensor and a clamping device. When the moving speed of the connecting rope 117 exceeds a preset safety threshold, the speed sensor will immediately detect this abnormal situation and trigger the clamping device to quickly clamp the connecting rope 117. In this way, the movement of the connecting rod 104 can be stopped immediately to ensure the safety of the patient.

[0071] Through the integration of the control modules, the patient nursing turning device of the present invention realizes highly intelligent operation, reduces the labor intensity of medical staff, and improves nursing efficiency.

[0072] Second embodiment

[0073] See also Figure 7 Based on the first embodiment, the present invention further provides a patient nursing turning method, comprising:

[0074] S201: placing a patient on a bed board 102, with a plurality of bandages 103 under the patient;

[0075] Make sure the bed board 102 is flat, clean, and free of foreign matter. Place a mattress on the bed board 102 to ensure the comfort of the patient when lying down. Prepare multiple bandages 103, and make sure that the material of the bandages 103 is soft and strong enough to safely support and move the patient. With the help of medical staff, carefully transfer the patient to the bed board 102 and ensure that the patient is in a comfortable position. Place multiple bandages 103 evenly under the patient, and make sure that each bandage 103 is laid flat on the bed board 102 without twists or knots. The distribution of the bandages 103 should cover the patient's back, waist, and legs to provide comprehensive support.

[0076] S202: adjusting the position of the bandage 103 on the connecting rod 104 relative to the connecting rod 104, and then driving the two connecting rods 104 to rise and fall through the two driving units 106 in sequence to adjust the position of the bandage 103 under the patient;

[0077] Make sure that each connecting buckle 108 is correctly installed on the connecting rod 104, and the locking rod 110 is firmly inserted into the connecting groove. According to the specific body shape and turning needs of the patient, manually adjust the position of the bandage 103 on the connecting rod 104 to ensure that the bandage 103 can be evenly distributed under the patient.

[0078] The first drive unit 106 is started to slowly raise the connecting rod 104 along the L-shaped guide rail 105. At this time, the bandage 103 will gradually tighten and begin to support the patient's back. After the connecting rod 104 is raised to an appropriate height, the position of the bandage 103 is manually fine-tuned again to ensure that the patient feels comfortable and the bandage 103 is evenly distributed.

[0079] The second drive unit 106 is started to slowly raise the other connecting rod 104, while the first connecting rod 104 gradually descends. This process can further adjust the bandage 103 under the patient, ensuring that the patient is always in a safe and comfortable state during the whole process.

[0080] S203 starts the driving unit 106 to drive the connecting rod 104 to move along the L-shaped guide rail 105 to drive the patient to turn over to a specified angle.

[0081] The target angle at which the patient needs to turn over is set through the interface of the control module. This angle can be adjusted according to the specific needs of the patient and the doctor's advice. The drive unit 106 is started to slowly move the connecting rod 104 along the L-shaped guide rail 105. The drive unit 106 will accurately control the moving distance and speed of the connecting rod 104 according to the set angle.

[0082] The process of the patient turning over is monitored in real time through the display screen of the control module. The moving speed and position of the connecting rod 104 are ensured to be within a safe range. If any abnormality is found during the turning over process, such as the patient feeling uncomfortable or the equipment malfunctioning, the emergency stop button can be immediately pressed to stop the operation of the driving unit 106 to ensure the safety of the patient.

[0083] When the patient turns over to the specified angle, the control module confirms whether the position of the connecting rod 104 is correct, ensuring that the patient is in a stable and comfortable state. If necessary, the position of the bandage 103 can be manually adjusted again to ensure that the patient is always in the best support state during the entire turning process.

[0084] Through the above steps, the patient care turning method can not only help patients change their body positions efficiently and safely, but also greatly reduce the workload of medical staff. This method combines automation technology and humanized design to ensure the comfort and safety of patients during the turning process, and effectively prevent the occurrence of complications such as bedsores.

[0085] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
