[0002] In the field of medical care, long-term bedridden patients need to be turned over regularly to prevent pressure sores and improve blood circulation and respiratory function due to their limited physical mobility. Traditional turning methods rely on manual operation, which has the following defects: manual turning requires the collaboration of multiple caregivers, a single operation takes a long time (about 3-5 minutes), and it is difficult to achieve standardized turning angle and speed control, resulting in limited nursing efficiency. During manual handling, uneven force or operational errors can easily cause patient position displacement, skin abrasions, and even joint dislocations, especially for patients who have undergone surgery or fractures, and there is a risk of secondary injury.

[0003] Furthermore, frequent turning operations are physically demanding for caregivers, and long-term, high-intensity work can easily lead to occupational injuries.

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In order to more clearly explain and illustrate the technical solution and implementation of the present invention, preferred specific embodiments for implementing the technical solution of the present invention are introduced below.

[0028] Embodiment 1: This therapeutic nursing device consists of a therapeutic nursing bed mechanism 1 and two sets of auxiliary turning mechanisms 2. In the therapeutic nursing bed mechanism 1, universal rollers with hydraulic supports are installed at the four corners of the bottom of the nursing bed base 11 to facilitate movement and parking. The bottom of the electric lifting system 12 is fixed to the nursing bed base 11, and the lifting end is connected to the support bed board 16, and the mattress 17 is laid on the support bed board 16. The two sets of auxiliary turning mechanisms 2 are symmetrically arranged on the left and right sides of the top of the bed frame 14. Each group includes two servo motors 21, whose output shafts are connected to the screw rod 27 through a coupling. The outer ring of the screw rod 27 is matched with the nut 210, and the two sides of the nut 210 are connected to the movable crossbeam 23. A drive motor 25 is installed on the front movable crossbeam 23. The drive motor 25 is connected to one end of the nursing sheet 3 through the transmission shaft 4, and the other end is fixed to the opposite side transmission shaft 4, forming a continuous sheet structure surrounding the mattress 17.

[0029] The electric lifting system 12 adopts a dual-motor independent drive structure. The front and rear support bed boards 16 are controlled by two sets of electric push rods respectively. The push rod stroke is 0-30cm and the maximum thrust is 500N. The built-in pressure sensor of the push rod monitors the load in real time to avoid overload and jamming. The middle section of the support bed board 16 is connected by a double hinge. The hinge shaft diameter is 20mm and the surface is hard chrome-plated. It supports ±45° tilt adjustment to meet the needs of different turning over angles. The nursing bed fence 13 adopts a gas spring assisted lifting structure. The single-side fence can bear 50kg and is locked by a magnetic buckle when descending to prevent accidental rebound. The mattress 17 is a four-layer composite structure, including an anti-slip layer + memory foam layer + pressure sensing layer + waterproof layer. The pressure sensing layer has a resolution of 1cm 2, which can collect the patient's body pressure distribution data in real time and transmit it to the control system to generate turning suggestions.

[0030] The servo motor 21 uses a high-precision planetary reduction motor that supports PWM speed regulation with a speed range of 0-100rpm to meet different turning speed requirements. The lead screw 27 is a trapezoidal lead screw with a titanium-plated surface. The nut 210 has a built-in double-row angular contact ball bearing with adjustable preload to eliminate axial clearance. The guide rod 28 is a 16mm diameter chrome-plated smooth shaft that cooperates with the roller 29 to achieve low-friction guidance. The nursing sheet 3 is woven from medical-grade high-strength polyester fiber and coated with an antibacterial coating on the surface, which supports high-temperature disinfection at 120°C. The drive shaft 4 is a hollow shaft with a diameter of 25mm. The surface has spiral grooves to fix the sheet, and both ends are connected to the fixed block 24 through deep groove ball bearings.

[0031] The rotation of the screw 27 drives the nut 210 upward at a speed of 5mm / s, synchronously driving the movable crossbeam 23 to rise. The left-side drive motor 25 rewinds the sheet at a speed of 20rpm, while the right-side drive shaft 4 passively unwinds it, creating a 15° tilt angle for the sheet. The pressure sensing layer monitors body pressure distribution in real time. If the pressure at a single point exceeds 80mmHg for 30 seconds, it automatically pauses and issues an alarm. A PID algorithm controls the differential speed of the servo motors 21 on both sides, enabling continuously adjustable sheet tilt from 0-30°. This, combined with the bed lift system, creates a compound angle, such as a 10° forward tilt for the bed and a 15° left tilt for the sheet, reducing sheet traction to ≤30N. The turning angle and speed are dynamically adjusted based on data from the pressure sensing layer. For example, if the buttocks pressure exceeds 70mmHg, the bed board in the buttocks area is prioritized for lifting, while the corresponding sheet is rewound simultaneously. The device also supports pre-set turning intervals, automatically initiating the turning process upon reaching the desired interval and providing voice prompts for patient compliance. Furthermore, infrared sensors are installed on the edges of the movable crossbeam 23. If an obstacle is detected, the machine stops within 0.2 seconds, and the nut 210 retracts 5mm in the opposite direction. The drive motor 25 has a built-in current sensor that automatically shuts off when the load current exceeds 3A, preventing sheet tearing. A nylon anti-fall net is installed on the top of the bed frame 14 to prevent the patient from sliding during turning. Mushroom-shaped emergency stop buttons are located on both sides of the bed, and a wireless remote control can be used to power off the bed, braking all motors.

[0032] When assisting the patient to turn to the left, the servo motor 21 of the left-side assisting turning mechanism 2 is activated. The screw 27 rotates, driving the nut 210 upward along the guide rod 28. The roller 29 rolls along the guide rod 28, ensuring the smooth elevation of the movable crossbeam 23. Simultaneously, the left-side drive motor 25 rotates the transmission shaft 4 clockwise, passively unwinding the right-side transmission shaft 4. The left side of the nursing sheet 3 is gradually reeled in, while the right side is relaxed, allowing the patient to tilt with the sheet and turn. Turning to the right side proceeds similarly, simply by reversing the corresponding mechanism.

[0033] Example 2: Building on Example 1, the electric lift system 12 can be linked to the auxiliary turning mechanism 2. For example, when a patient requires a larger angle of rotation, the left auxiliary turning mechanism 2 is raised while the electric lift system 12 simultaneously raises the front or rear half of the support bed board 16 along the mid-section hinge point, creating a compound tilt angle. Specifically, when the left auxiliary turning mechanism 2 is raised 15 cm, the electric lift system 12 simultaneously raises the front half of the bed board 10°. This dual angle reduction reduces the pulling pressure on the nursing sheet 3 and reduces friction on the patient's skin.

[0034] Example 3: If an emergency occurs during turning, the system can quickly reset. The servo motor 21 rotates in reverse, the screw 27 drives the nut 210 downward, and the movable crossbeam 23 returns to its original position. Simultaneously, the drive motor 25 rotates in the opposite direction, and the drive shafts 4 on both sides simultaneously retract and unreel, restoring the nursing sheet 3 to a flat state. The electric lift system 12 also adjusts the support bed board 16 to a horizontal position to ensure patient safety.

[0035] Example 4: The treatment and nursing device of the present invention can be used in a variety of environmental scenarios, such as hospitals, airplane rescue and field rescue treatment, etc., to facilitate the patient's turning and nursing treatment. In response to different environmental scenarios and different patient needs, the device can preset a variety of turning modes. The left auxiliary turning mechanism 2 is lifted in three stages, with an interval of 5 seconds between each stage, and the nursing sheet 3 is slowly rolled up to suit the elderly or postoperative patients. The left and right auxiliary turning mechanisms 2 are lifted alternately to simulate manual left and right turning movements, which is suitable for long-term bedridden patients to prevent pressure sores. Only the servo motor 21 on one side is started to lift the movable crossbeam 23 on the corresponding side to achieve local tilting, such as raising only the waist to meet special nursing needs.

[0036] According to the content of the preferred technical solution described above, the workflow of the technical solution is explained: the user issues an operation instruction through the bed control panel, wireless remote control or mobile APP, and the system executes the self-test program after receiving the instruction: synchronously detects the stroke position of the two sets of push rods in the electric lifting system 12 and the zero drift of the pressure sensor, the encoder feedback value of the servo motor 21 and the initial preload of the screw transmission assembly, the winding tension of the nursing sheet 3 and the axial clearance of the transmission shaft 4, and the signal stability of each area of the pressure sensing layer of the mattress 17. At the same time, the voltage fluctuation range of the power module, the trigger sensitivity of the emergency stop button and the locking status of the universal roller hydraulic support are checked. After the self-test is completed, the user is prompted by the indicator light and voice that the device is ready.

[0037] Select the left or right turning direction, set the target tilt angle, operating speed and duration, and the system automatically calculates the theoretical number of rotations of the screw 27, the PWM duty cycle of the servo motor 21 and the speed compensation coefficient of the drive motor 25; set the differentiated parameters of the auxiliary turning mechanism 2 on the left and right sides respectively, such as 15° on the left side + 5° on the right side, generate a differential control curve through the PID algorithm, and synchronously adjust the segmented tilt angle of the bed board of the electric lifting system 12; the system automatically generates an optimized combination of turning angle, speed and duration based on the body pressure distribution data, hip / shoulder / back pressure value and contact area collected in real time by the pressure sensing layer of the mattress 17, and dynamically adjusts the winding and unwinding synchronization of the drive shaft 4.

[0038] The target side servo motor 21 is started, the screw rod 27 receives the torque output through the coupling, the nut 210 is lifted vertically along the guide rod 28, the rolling friction coefficient between the roller 29 and the guide rod 28 is controlled within the range of 0.05-0.1, and the movable beam 23 is lifted at the set speed; the drive motor 25 is started synchronously, and the transmission shaft 4 applies traction to the nursing sheet 3 through the spiral groove. The sheet tension is fed back to the control system through the built-in tension sensor. When the tension value exceeds the preset threshold of 25-35N, the speed of the servo motor 21 is automatically reduced and the torque output of the drive motor 25 is increased; if the bilateral collaborative mode is selected, the servo motor 21 on the other side runs at a differential speed to form a compound tilt angle. At the same time, the electric lifting system 12 controls the segmented tilt of the bed board according to the program instructions, and the collaborative motion trajectory of the bed board and the bed sheet is solved in real time through the kinematic equation.

[0039] The pressure sensing layer collects body pressure data at a frequency of 100Hz, combines the turning angle and speed parameters, and dynamically evaluates the patient's body position stability through a fuzzy control algorithm; the infrared sensor continuously monitors the distance between the movable beam 23 and the edge of the bed, triggering a deceleration signal when the distance is less than 5cm, and immediately shuts down when the distance is less than 2cm; the current sensor monitors the load current of the drive motor 25 in real time. If the current value exceeds the rated value of 3A for 0.5s, it is determined that the bed sheet is abnormally entangled or mechanically blocked, and the system automatically executes the reverse reset procedure and alarms.

[0040] After reaching the set time or target angle, the servo motor 21 enters the position holding mode, maintains the height of the nut 210 through current closed-loop control, and the drive motor 25 stops rotating and applies braking torque to prevent the transmission shaft 4 from continuing to rotate due to inertia; the electric lifting system 12 locks the segmented tilt angle of the bed board, and the pressure sensing layer continuously monitors the body pressure distribution. If the single-point pressure is greater than 80 mmHg for 30 seconds, it is judged as an improper posture and the fine-tuning program is automatically triggered to compensate for the ±2° angle.

[0041] After the user sends a reset command through the control terminal, the servo motor 21 reverses and the nut 210 descends at a set speed. During the descent, the drive motor 25 rotates in the opposite direction to release the tension of the sheet. The unwinding speed of the drive shaft 4 and the descending speed of the nut 210 are synchronized through encoder feedback. During the reset process, the infrared sensor and the limit switch dually monitor the position of the movable beam 23. When the reset position signal is detected, the servo motor 21 and the drive motor 25 are powered off at the same time, and the bed body returns to its initial horizontal state.

[0042] The system automatically generates a log of the turning process, records the timestamp, mode type, parameter setting value, sensor data and device status code, and uploads it to the nursing information system via wired / wireless means; if a fault occurs (such as motor overload, sensor failure, mechanical jam), the system will immediately shut down and activate the sound and light alarm, and the fault information will be pushed to the administrator terminal at the same time; users can view historical operation records and fault logs through the control terminal; combined with VR equipment and electromyography sensors, the resistance coefficient is dynamically adjusted according to the degree of muscle activation during the patient's turning process, and a training intensity curve is generated and synchronized to the rehabilitation assessment system; it supports voice command control (such as "turn left 10 degrees" and "pause for 5 minutes"), analyzes user intentions through NLP algorithms, and pushes the device status and turning plan to the family's mobile phone to achieve remote monitoring and intervention.

Anyone should be aware that any structural changes made under the guidance of the present invention, and any technical solutions that are the same or similar to those of the present invention, fall within the scope of protection of the present invention.
