Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an ECMO patient assisted rehabilitation device. Background Art

[0002] ECMO (extracorporeal membrane oxygenation) is a life-saving method that has been increasingly applied in the treatment of acute reversible respiratory and circulatory failure in recent years, such as ARDS, fulminant myocarditis, cardiogenic shock, etc. It is mainly divided into two modes: venovenous (VV) or venoarterial (VA).

[0003] Traditional ECMO requires patients to stay in a fixed bed for a long time and cannot move. Long-term bed rest, accompanied by a large number of tubes and devices connected to the body, limits activities, which not only leads to complications such as muscle atrophy, joint stiffness, and pressure sores, but also seriously affects the mental health and social ability of patients. Therefore, a mobile ECMO can help ECMO patients move from in-bed treatment to free activities indoors and outdoors. Such a mobile ECMO device needs to include a moving mechanism capable of carrying the patient and a carrying box for carrying the ECMO machine;

[0004] However, since the ECMO machine generally needs to be inserted into the patient's body through two relatively thick tubes to separately be responsible for drawing the patient's blood out of the body into the ECMO machine for oxygenation and removing carbon dioxide, designing a mobile ECMO device increases the degree of freedom of the patient while being accompanied by the risks of the two functional tubes being twisted, blocked, or detached, further bringing complications such as patient bleeding, thrombosis, and infection caused by unstable pumping. Therefore, it is necessary to propose an ECMO patient assisted rehabilitation device that can improve the treatment effect and reduce the probability of causing complications. Summary of the Invention

[0005] To solve the above problems, the present invention provides an ECMO patient assisted rehabilitation device, which integrates an ECMO machine and a patient moving platform, proposes a mobile ECMO device, and designs to increase the degree of freedom of the patient's ECMO pumping function pipeline, combined with real-time monitoring and prediction of the pumping pipeline, to improve the treatment effect and treatment safety of ECMO.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an ECMO patient auxiliary rehabilitation device, comprising a load-bearing frame, an ECMO machine and an electrocardiogram monitor are arranged in the load-bearing frame, the ECMO machine is connected with two functional tubes, a vertical partition is fixedly connected in the load-bearing frame, the partition separates the load-bearing frame into an equipment chamber and an activity chamber, a folding seat is fixedly connected to one side of the inner wall of the activity chamber, a first equipment platform and a second equipment platform are fixedly connected to the bottom of the inner wall of the equipment chamber, the ECMO machine and the electrocardiogram monitor are respectively located on the first equipment platform and the second equipment platform, the ECMO machine signal is connected with a control system, and an alarm component for reminding medical staff to take emergency measures to interfere with the patient's actions is arranged on the outer wall of the load-bearing frame;

[0007] Symmetrical sliding grooves are provided on the partitions, and sliding blocks with annular structures are slidably connected in the sliding grooves. Active balls are hinged in the sliding blocks. Placement pipes are provided in the active balls. Elastic components for elastically resetting functional tubes are provided in the placement pipes. The ECMO machine is connected with two functional tubes, and the functional tubes extend from the equipment cavity to the active cavity through corresponding placement pipes.

[0008] The technical principles of the above scheme are as follows: through the combination of the load-bearing frame and the mobile component, the transfer and movement of the patient can be realized, and the ECMO machine and its related components are effectively isolated from the patient's folding seat and activity area through the division of the equipment cavity and the activity cavity; by opening symmetrical sliding grooves on the partition and slidingly connecting the sliding blocks of the annular structure, the functional pipeline is provided with the freedom of lateral displacement, and the real-time monitoring and prediction of the pumping pipeline can be realized through the design of the control system. Through the unique fixing mechanism design of the functional tube, the functional tube is provided with the freedom of up and down tilting; the elastic reset mechanism is realized through the design of the elastic component, which helps to keep the pipeline smooth, and the patient's key physiological indicators are displayed in real time through the design of the alarm component.

[0009] The above scheme has the following beneficial effects:

[0010] 1. This solution, through the design of the sliding groove and the sliding block, realizes the flexible response of the functional tube to the patient's movements. When the patient moves laterally, the sliding block can move smoothly in the sliding groove, driving the functional tube to move with it, thereby greatly reducing the probability of the functional tube being bent and twisted due to the patient's movement. It not only ensures the smooth passage of the functional tube, but also reduces the blood flow resistance caused by the twisting of the pipeline, which helps to maintain stable blood circulation. In addition, the symmetrically separated sliding groove design cleverly avoids the entanglement between the functional tubes, ensuring the continuity and safety of the treatment, not only saving space, but also improving the reliability and ease of use of the entire rehabilitation equipment.

[0011] 2. The combination of the movable ball hinge design and the function of the placement pipe clamping the functional pipe in this solution provides great convenience for the patient to stretch the functional pipe when standing up. When the patient stands up or performs other actions that cause the functional pipe to be stretched, the movable ball can rotate freely, enabling the functional pipe to smoothly follow the moving direction and rotate accordingly. This design ensures that the functional pipe always passes through the movable ball in the way with the minimum bending degree, thereby reducing the pressure and resistance generated by bending, helping to protect blood vessels and reducing the risk of thrombosis. At the same time, this flexible rotation design also improves the comfort of the patient, enabling the patient to move more freely during rehabilitation exercises.

[0012] 3. This solution also ingeniously designs an elastic component to deal with the situation where the functional pipe is stretched when the patient completes rehabilitation exercises or under the action of other external forces. When the functional pipe is stretched, the length of the functional pipe in the movable cavity increases, while the length of the functional pipe in the device cavity remains unchanged. At this time, the elastic component plays an important role. It can provide the necessary resilience when the patient's posture returns to its original position, enabling the functional pipe to return to its position following the patient's movement. This design not only ensures the stability and continuity of the functional pipe but also avoids the risk of damage or detachment caused by excessive stretching of the pipe. At the same time, the buffering effect of the elastic component also reduces the impact force on the pipe during the patient's movement, improving the safety and comfort of the entire rehabilitation process.

[0013] Furthermore, a display window is provided on the side wall of the device cavity away from the movable cavity. The position where the display window is opened corresponds to the position where the electrocardiogram monitor is placed, and the electrocardiogram monitor is signal-connected to the control system.

[0014] Beneficial effects: Through the design of the display window, medical staff can observe the vital sign data of the patient at any time and anywhere without interrupting other medical operations, improving work efficiency, and enabling the monitoring data of the electrocardiogram monitor to be fully utilized, which helps medical staff to detect and handle abnormal situations in a timely manner and improves the overall efficiency of the device.

[0015] Furthermore, the alarm component includes a buzzer alarm fixedly connected to the outer side wall of the bearing frame, and the buzzer alarm is signal-connected to the control system.

[0016] Beneficial effects: The design of the buzzer alarm can immediately issue an alarm when detecting abnormal situations (such as the functional pipe being stretched beyond the threshold, the power supply being too low, etc.), reminding medical staff to take timely measures for intervention, ensuring that medical staff can respond quickly and handle potential risks, thereby guaranteeing the safety and treatment effect of the patient.

[0017] Furthermore, both ends of the two placement pipes are of rounded corner structures and are fixedly connected with elastic layers.

[0018] Beneficial effects: The rounded corner structure can effectively disperse stress concentration, reduce the pressure and resistance generated when the pipeline is bent, thereby reducing the risk of pipeline damage. At the same time, the setting of the elastic layer increases the flexibility and wear resistance of the pipeline, further protects the pipeline, and extends its service life. It not only ensures the continuity and safety of treatment, but also improves the comfort of patients, which is an important manifestation of the humanized design of the equipment.

[0019] Furthermore, each elastic component includes a spring located in the middle of the inner wall of the placement pipeline. One end of the spring is fixedly connected to the inner wall of the placement pipeline, and the other end of the spring is fixedly connected to a sleeve ring, and the radius of the sleeve ring is equal to the radius of the functional tube.

[0020] Beneficial effects: Through the spring design, excellent support and protection are provided for the functional tube. Regardless of the position or state of the functional tube, the spring can be stretched or compressed moderately as needed, thereby maintaining the stability and smooth movement of the functional tube. The design of the sleeve ring, with its radius equal to the radius of the functional tube, ensures the precise positioning of the functional tube in the placement pipeline, avoiding accidental detachment or connection loosening caused by movement or vibration. In addition, the elastic effect of the spring can also provide necessary buffering and resilience when the functional tube is subjected to external forces, effectively reducing the bending and twisting of the functional tube, further reducing the risk of thrombus formation, and ensuring the continuity of the treatment process and the safety of the patient.

[0021] Furthermore, insertion grooves corresponding to the partition plates are provided on the inner side wall of the bearing frame. The partition plates, sliding blocks, movable balls, and sleeve rings are all designed as detachable structures, and the partition plates are slidably matched with the insertion grooves.

[0022] Beneficial effects: This design enables medical staff to quickly and easily remove the partition plate along the insertion groove, disassemble and assemble the sliding block, movable ball, and sleeve ring when the patient needs to be transferred from the hospital bed to the ECMO equipment, and then place the functional tube in the placement pipeline, saving precious treatment time. At the same time, the detachable structure also reduces the operation difficulty and the risks that may be brought about by improper operation. In addition, this design also facilitates the cleaning, maintenance, and replacement of components of the equipment, helps to extend the service life of the equipment, and improves the overall treatment effect and safety.

[0023] Furthermore, angle sensors are provided on both sides of the movable ball. The angle sensors are adhered to the outer side of the corresponding functional tube through Velcro, and the angle sensors are all signal-connected to the control system.

[0024] Beneficial effects: Angle sensors are provided on both sides of the movable ball to achieve real-time monitoring of the bending angle of the functional tube, enabling the control system to accurately obtain the angle change data of the functional tube during movement, ensuring the immediate transmission and processing of the data. By analyzing this data, the control system can evaluate the bending degree of the functional tube and its impact on the patient's blood circulation, thereby promptly detecting and warning of potential risks such as increased blood flow resistance and thrombus formation. This not only improves the safety of the treatment process but also provides medical staff with a more accurate means of monitoring the patient's condition, helping them make more timely treatment adjustments and ensuring the patient's recovery effect.

[0025] Furthermore, displacement sensors are fixedly connected to one side of the sleeve ring, and the displacement sensors are all signal-connected to the control system.

[0026] Beneficial effects: Through the design of the displacement sensors and signal connection with the control system, real-time monitoring of the stretching length of the functional tube is achieved. The displacement sensors can accurately capture the stretching changes of the functional tube caused by patient movement or external factors and convert this change into an electrical signal and transmit it to the control system. The control system can perform real-time analysis and judgment on the stretching length according to the preset threshold. Once the stretching length exceeds the safe range, the system immediately triggers an alarm to remind medical staff to pay attention and take corresponding treatment measures, improving the monitoring accuracy of the functional tube status and effectively reducing the potential risks caused by excessive stretching of the functional tube, ensuring the treatment safety of the patient.

[0027] Furthermore, the control system includes a displacement acquisition module, an angle acquisition module, a blood pressure acquisition module, a monitoring module, an analysis module, and an alarm module;

[0028] The displacement acquisition module is used to respectively and real-time capture and acquire the stretching displacements of the corresponding functional tubes according to the two displacement sensors, that is, convert the stretching change electrical signal of the functional tube into a stretching displacement value, and set a stretching threshold according to the actual material, diameter, working conditions, and safety standard length of the functional tube;

[0029] The angle acquisition module is used to acquire the corresponding angle information through two angle sensors respectively installed on both sides of the two placement tubes, that is, the two angle sensors respectively detect the angle information of one end of the functional tube entering the placement tube and the other end extending out of the placement tube. The collected data is represented by positive and negative angles. A positive angle represents the upward bending angle of the functional tube on this side, and a negative angle represents the downward bending angle of the functional tube on this side;

[0030] The blood pressure acquisition module real-time acquires the patient's blood pressure and blood flow velocity data recorded by the electrocardiogram monitor;

[0031] The monitoring module is used to continuously monitor the change of the stretching length according to a preset stretching threshold. When the stretching length collected by the displacement acquisition module exceeds the stretching threshold, the monitoring module immediately triggers an alarm mechanism and transmits a signal to the alarm module.

[0032] The analysis module is used to perform calculations and analysis predictions based on the stretching length and angle data collected in real time, analyze and predict the predicted bending risk of the functional tube due to the patient's movement, and monitor this predicted bending risk.

[0033] The alarm module is used to receive signals from the monitoring module and the analysis module, transmit a driving signal to the buzzer alarm, and the buzzer alarm emits an alarm sound to remind medical staff to take timely measures for intervention and treatment.

[0034] Beneficial effects: Through the collaborative work of each module, the control system of this ECMO patient assisted rehabilitation device realizes the real-time monitoring, analysis and early warning of the functional tube, ensures the safe and effective operation of the device, and provides strong support for the rehabilitation treatment of ECMO patients.

[0035] Furthermore, in the analysis module, the analysis and prediction of the patient's movement risks include:

[0036] Data preprocessing: Preprocess the stretching length and angle data collected in real time, including data denoising, filtering and calibration.

[0037] Physical model establishment: Based on the material, diameter and side wall thickness of the pipeline recorded in the ECMO machine, as well as the blood flow velocity and blood pressure collected by the blood pressure acquisition module, establish a corresponding physical model.

[0038] Calculation and analysis: On the basis of the physical model, calculate the stress distribution, strain energy and fatigue life parameters of the corresponding functional tube, and evaluate the influence of the bending angle of the pipeline on blood flow resistance and thrombus formation according to these data, that is, respectively calculate the remaining pipeline lengths of the functional tube in the activity cavity and the device cavity according to the stretching displacement data, and then convert the corresponding bending angles collected in the activity cavity and the device cavity into attenuation coefficients, and finally calculate and evaluate the predicted bending rate of the pipeline, presented in the form of a percentage.

[0039] Risk assessment and decision-making: According to the predicted bending rate, evaluate the potential risks. When the predicted bending rate exceeds 60%, that is, the predicted bending angle exceeds 108°, the potential risk is evaluated as a high risk. When the predicted bending rate is lower than 20%, that is, the predicted bending angle is lower than 36°, the potential risk is evaluated as a low risk. When the predicted bending rate is 20%-60%, the potential risk is evaluated as a medium risk. When the potential risk assessment reaches a high risk, transmit a signal to the alarm module.

[0040] Beneficial effects: The analysis module can comprehensively and accurately analyze and predict the movement risks of patients. Through the data preprocessing steps, the accuracy of the stretching length and angle data collected in real time is ensured, providing a reliable basis for subsequent analysis; the establishment of the physical model is based on the detailed parameters of the pipeline recorded in the ECMO machine, making the analysis closer to the actual situation. In the calculation and analysis stage, not only key parameters such as the stress distribution, strain energy, and fatigue life of the functional pipe are calculated, but also by comprehensively considering factors such as the bending angle of the pipeline and the remaining pipeline length, the influence of the bending angle on blood flow resistance and thrombus formation is innovatively evaluated and presented in the intuitive index of the bending rate. Finally, in the risk assessment and decision-making step, the fatigue degree and potential risks of the pipeline are evaluated according to the bending rate, and important information is transmitted to the display module in real time for medical staff to refer to, improving the safety of the treatment process and the effect of patient rehabilitation.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0050] The following will be further described in detail through specific embodiments:

[0051] Embodiment 1:

[0052] As shown in Figure 1 , Figure 2 and Figure 3 : An ECMO patient assisted rehabilitation device includes a carrying frame 1. A vertical partition 5 is welded inside the carrying frame 1. The partition 5 divides the carrying frame 1 into a device cavity 101 and an activity cavity 102. The activity cavity 102 is used to provide a space for the patient to move, and the device cavity 101 is used to place the ECMO machine 6. The design of the partition 5 ensures the mutual independence of each functional area and does not interfere with each other.

[0053] A switch door is provided on one side of the activity cavity 102. The switch door is hinged to the carrying frame through a hinge mechanism, ensuring the mobility inside the activity cavity 102. Its operation is simple and convenient. The patient can easily open the switch door with the assistance of medical staff and enter the activity cavity 102 for rehabilitation exercises or the behavior of transporting patients.

[0054] Inside the equipment cavity 101, the first equipment platform 2 and the second equipment platform 12 are welded. On the surface of the first equipment platform 2, an ECMO machine 6 is placed. On the surface of the second equipment platform 12, an electrocardiogram monitor 13 is placed. The ECMO machine 6 is electrically connected to the electrocardiogram monitor 13, realizing real-time monitoring and data transmission of the patient's vital signs. This design ensures that the electrocardiogram monitor 13 can accurately capture and display the patient's key physiological parameters, providing crucial basis for clinical decision-making. In addition, on the side of the equipment cavity 101 far from the activity cavity 102, a display window 20 corresponding to the position of the electrocardiogram monitor 13 is opened, enabling medical staff to clearly observe the display interface of the electrocardiogram monitor 13 through this display window 20, thus realizing instant monitoring and analysis of the patient's vital sign data.

[0055] At the bottom of the bearing frame 1, a moving component 4 is provided. The moving component 4 includes several electronically controlled resistance wheels. The several electronically controlled resistance wheels are respectively installed at the four corners of the bottom surface of the bearing frame 1. The core working principle of the electronically controlled resistance wheels is based on advanced electronic drive and resistance regulation technology. By precisely adjusting the output of the drive power, the contact resistance between the wheel and the ground can be dynamically increased or decreased, thereby effectively controlling the moving speed and difficulty of the overall bearing frame 1. This design not only endows the bearing frame 1 with flexible and reliable moving performance, but more importantly, it ingeniously combines the moving function with the patient's rehabilitation exercise needs. With the dynamic adjustment of the resistance of the electronically controlled resistance wheels, when the patient is performing rehabilitation walking or displacement training, different degrees of resistance challenges are encountered, so that the exercise intensity can be adjusted according to the individual's rehabilitation stage and physical condition, realizing personalized rehabilitation training goals.

[0056] A folding seat 3 is hinged on the side wall of the activity cavity 102, and a through hole 21 is provided at the bottom of the activity cavity 102. This design ensures that the patient can easily place their legs on the ground through this through hole 21, and then perform rehabilitation exercise actions such as standing and walking, which is of great help for promoting the recovery of the patient's lower limb function, enhancing muscle strength and improving body balance ability. The design of the folding seat can not only provide a comfortable sitting posture support conforming to the physiological curve for the patient, facilitating sitting and resting to restore physical strength after completing a series of rehabilitation exercises, but also its folding and storage function greatly saves space resources, avoiding the unnecessary area occupied by traditional seats when not in use, thus significantly improving the functional integration and space utilization efficiency of the overall equipment.

[0057] The ECMO machine 6 is fixedly connected with two functional tubes 11 through buckles. Since both of the two functional tubes 11 need to be inserted into the patient's body for a long time to achieve their functions and maintain the patient's life, the twisting and folding of the functional tubes 11 directly affect the blood flow in the tubes. Whether it is the venous drainage end or other parts of the tubes, folding increases the resistance, resulting in a decrease in the flow rate of the ECMO machine 6. At the venous drainage end, twisting and folding may cause poor drainage, forming a high negative pressure that damages the inner wall of the blood vessel, increasing the risk of bleeding and thrombosis. In addition, long-term twisting and folding of the tubes may cause blood to stagnate in the tubes, increasing the risk of thrombosis and triggering serious complications such as pulmonary embolism. Therefore, in order to achieve the effect of preventing twisting and folding, symmetric sliding grooves 7 are provided on the partition plate 5. Taking one of the sliding grooves 7 as an example, a sliding block 8 is slidably connected in the sliding groove 7 through a chute structure, and the sliding block 8 is of an annular structure. The sliding connection design enables the functional tube 11 to move smoothly and freely left and right along the sliding groove 7 without being subjected to excessive frictional resistance. When the patient needs to move, the functional tube 11 can move smoothly left and right, improving the performance of the device and bringing a more convenient and efficient user experience.

[0058] A movable ball 9 is ball-jointed inside the sliding block 8, and a placement pipe 10 is provided inside the movable ball 9. The functional tube 11 extends from the device cavity 101 through the placement pipe 10 into the movable cavity 102 and is inserted into the patient's body. When the functional tube 11 is subjected to an external force (i.e., the patient moves up and down during rehabilitation exercises), the ball-joint structure allows the movable ball 9 to rotate freely and fine-tune within a certain range, thus preventing the functional tube 11 from being folded or twisted due to excessive pressure or twisting force. This not only improves the stability and durability of the functional tube 11 but also ensures the smooth progress of the medical process, bringing a more comfortable and safe medical experience to the patient.

[0059] Both ends of the placement pipe 10 are rounded at the connection with the movable ball 9 and are inlaid with an elastic layer 15. The rounded design can effectively disperse stress concentration. During the process of the functional tube 11 extending through the placement pipe 10 into the movable cavity 102 and being inserted into the patient's body, the functional tube 11 bends at the opening inside the placement pipe 10 and is subjected to forces and torques from all directions. Traditional right-angle or acute-angle connections often become areas of stress concentration, easily causing plastic deformation of the pipe material at these parts, which may then lead to bending or damage. The rounded design, on the other hand, evenly distributes the stress over a larger area through a smooth transition, thus greatly reducing the risk of pipe bending. In addition, the setting of the elastic layer 15 increases the flexibility and wear resistance of the pipe, further protecting the pipe and extending its service life. This not only ensures the continuity and safety of the treatment but also improves the patient's comfort, which is an important manifestation of the humanized design of the device.

[0060] In addition, during the patient's rehabilitation exercise or other displacement processes, the functional tube 11 may be stretched, and when the movement returns to its original position, it may not retract smoothly due to the influence of friction, resulting in a decrease in the vertical height. This may cause the connection point between the functional tube 11 and the placement tube 10 with a constant vertical height to bend, and further may cause the connection point between the functional tube 11 and the placement tube 10 to bend or twist. Therefore, in order to avoid such folding and distortion of the functional tube 11, springs 16 are welded in the middle of the inner wall of the placement tube 10. One end of the spring 16 away from the inner wall of the tube 10 is welded with a sleeve ring 17, and the radius of the sleeve ring 17 is equal to the radius of the functional tube 11. When the patient stretches the functional tube 11 during the rehabilitation exercise, the spring 16 structure can be moderately stretched as the functional tube 11 moves, storing energy. When the patient's movement returns to its original position and the functional tube 11 starts to retract, the spring 16 releases the stored energy to assist the functional tube 11 to smoothly and quickly return to its original position, reducing the friction between the functional tube 11 and the placement tube 10, effectively avoiding the problem that the functional tube 11 cannot retract smoothly due to excessive friction, and also ensuring that the functional tube 11 is not damaged due to bending or twisting during the retraction process. In addition, the gradient spiral design of the spring 16 and the ingenious use of the sleeve ring 17 also form a dynamic adaptation mechanism between the inner wall of the placement tube 10 and the functional tube 11. No matter what position or state the functional tube 11 is in, the spring 16 and the sleeve ring 17 can provide stable support and protection, ensuring the smooth movement and long-term use of the functional tube 11.

[0061] Considering the design requirement that the patient and the ECMO (Extracorporeal Membrane Oxygenation) machine need to be safely separated by the partition plate 5, the two key functional tubes 11 must accurately extend from the equipment cavity 101 into the movable cavity 102 to ensure the continuity of the treatment process and the safety of the patient. To achieve this goal and fully consider the convenience and safety during the patient transfer process, the key components such as the partition plate 5, the sliding block 8, the movable ball 9, and the sleeve ring 17 are designed as detachable structures, ensuring the safety and comfort of the patient during the transfer from the hospital bed to the ECMO equipment. When the patient needs to be transferred from the hospital bed to the ECMO equipment, the medical staff can easily disassemble the partition plate 5, and this action will simultaneously drive components such as the sliding block 8, the movable ball 9, and the sleeve ring 17 to be detached from their original positions. This design makes the entire disassembly and assembly process simple and fast, greatly saving valuable treatment time, reducing the operation difficulty, and minimizing the risks that may be caused by improper operation. After disassembling the partition plate 5, the medical staff can quickly and accurately place the two functional tubes 11 into the prepared placement ducts 10 respectively. This step not only ensures that the functional tubes 11 can be smoothly connected to the patient and the ECMO machine 6, providing continuous and stable support for the patient's treatment, but also lays a solid foundation for the subsequent fixation of the functional tubes 11. Through reasonable layout and precise design, the positions of the functional tubes 11 in the placement ducts 10 are effectively fixed, thus avoiding accidental detachment or loose connection caused by movement or vibration, and ensuring the stability and safety of the treatment process.

[0062] Embodiment 2:

[0063] As shown in the attached Figure 1 and Figure 3 figure, the difference from Embodiment 1 is that since the conventional ECMO machine 6 and the two attached functional tubes 11 (i.e., the arterial tube and the venous tube) are equipped with specific blood pressure monitoring instruments, the pump pressure of the functional tubes 11 is understood by monitoring the blood pressure, so as to understand the patient's physiological state and adjust the treatment plan to ensure the safety and treatment effect of the patient. To improve the prediction of tube kinking and twisting (i.e., the risk prediction of tube kinking caused by the patient's movement) and further reduce the potential safety hazards during the patient's treatment, angle sensors 18 are provided on both sides of the movable ball 9. The angle sensors 18 are adhered to the outer sides of the corresponding functional tubes 11 through Velcro, and the angle sensors 18 are all signal-connected to the control system. By continuously monitoring the data output by the sensors, the control system can accurately calculate the bending degree of the functional tubes 11. When the tube is bent or twisted, the angle sensors 18 immediately capture this change and trigger the alarm system to remind the medical staff to check and correct the state of the tube in time.

[0064] In addition, displacement sensors 19 are fixedly connected to one side of the sleeve ring 17 by screws. The displacement sensors 19 are all signal-connected to the control system. The displacement sensors 19 can monitor the change in the tensile length of the sleeve ring 17 and the connected functional tube 11 in real time. When the pipeline is stretched due to various reasons (such as patient movement, external pressure, etc.), the displacement sensors 19 can quickly capture this change and transmit the signal to the control system. The control system can perform real-time analysis and judgment on the tensile length according to the preset threshold. Once it exceeds the safe range, the warning system will be immediately triggered to remind the medical staff to pay attention and take corresponding treatment measures.

[0065] A buzzer alarm 14 is fixedly connected to the outer wall of the bearing frame 1 by bolts. The buzzer alarm 14 is signal-connected to the control system. The design of the buzzer alarm 14 significantly improves the response speed of the system and the accuracy of alarm transmission. In specific situations (i.e., when the risk of pipeline folding is too high and the pipeline is stretched too long), once the control system detects an abnormality or a triggering condition, the buzzer alarm 14 can be immediately activated to emit a clear and loud alarm sound, effectively warning the medical staff, so as to take corresponding measures in time to avoid potential safety hazards or losses.

[0066] Embodiment 3:

[0067] As shown in the Figure 4 appendix, the difference from Embodiment 2 is that the control system includes a displacement acquisition module, an angle acquisition module, a blood pressure acquisition module, a monitoring module, an analysis module, and an alarm module;

[0068] The displacement acquisition module uses two displacement sensors 19 to capture and acquire the tensile displacement of the corresponding functional tube 11 in real time. The two sensors accurately convert the tensile change of the functional tube 11 into an electrical signal and further into a tensile displacement value. To ensure the safety of the patient during the treatment process and avoid the harm caused by the detachment of the functional tube 11 to the patient, the displacement acquisition module also presets a tensile threshold according to the actual material, diameter, working conditions, and safety standard length of the functional tube 11, and transmits the tensile threshold to the monitoring module.

[0069] The angle acquisition module uses two groups of angle sensors 18 respectively installed on both sides of the placement pipeline 10 to acquire the angle information of the functional tube 11 in the placement pipeline 10 in real time. These two angle sensors 18 can respectively detect the angles of the two ends of the functional tube 11 entering and exiting the placement pipeline 10. The acquired data is represented by positive and negative angles. A positive angle represents the upward bending angle of the functional tube 11 on this side, while a negative angle represents the downward bending angle of the functional tube 11 on this side, providing data support for subsequent analysis and risk assessment.

[0070] The blood pressure acquisition module acquires the patient's blood pressure and blood flow velocity data recorded by the electrocardiogram monitor in real time.

[0071] The monitoring module is mainly responsible for continuously monitoring the change of the stretching length. According to the preset stretching threshold, it conducts real-time comparison and analysis on the data transmitted by the displacement acquisition module. Once it is found that the stretching length exceeds the threshold, the monitoring module immediately triggers the alarm mechanism and transmits a signal to the alarm module so as to take corresponding measures in a timely manner.

[0072] The analysis module conducts calculations, analysis and prediction based on the stretching length and angle data collected in real time. The analysis and prediction of the patient's movement risks include:

[0073] Data preprocessing: Preprocess the stretching length and angle data collected in real time, including data denoising, filtering and calibration;

[0074] Physical model establishment: According to the material, diameter and side wall thickness of the pipeline recorded in the ECMO machine 6, as well as the blood flow velocity and blood pressure collected by the blood pressure acquisition module, establish the corresponding physical model;

[0075] Calculation and analysis: Based on the physical model, calculate the stress distribution, strain energy and fatigue life parameters of the corresponding functional pipe 11, and evaluate the influence of the bending angle of the pipeline on blood flow resistance and thrombus formation according to these data. That is, according to the stretching displacement data, respectively calculate the remaining pipeline lengths of the functional pipe 11 in the activity cavity 102 and the equipment cavity 101, and then convert the bending angles collected corresponding to the activity cavity 102 and the equipment cavity 101 into attenuation coefficients, and finally calculate and evaluate the predicted bending rate of the pipeline, which is presented in the form of a percentage;

[0076] Risk assessment and decision-making: According to the predicted bending rate, evaluate the potential risks. When the predicted bending rate exceeds 60%, that is, the predicted bending angle exceeds 108°, the potential risk is evaluated as a high risk. When the predicted bending rate is lower than 20%, that is, the predicted bending angle is lower than 36°, the potential risk is evaluated as a low risk. When the predicted bending rate is 20%-60%, the potential risk is evaluated as a medium risk. When the potential risk assessment reaches a high risk, a signal is transmitted to the alarm module.

[0077] The alarm module receives signals from the monitoring module and the analysis module. When it detects that the stretching length exceeds the threshold and the potential risk assessment reaches a high risk, it immediately transmits a signal to the buzzer alarm 14. The buzzer alarm 14 emits an alarm sound to remind the medical staff to take measures for intervention and treatment in a timely manner, which helps to ensure the safe operation of the system and timely response to potential risks.

[0078] Embodiment 4:

[0079] As shown in the appendix Figure 1As shown, the difference from Embodiment 3 is that an infusion rack is welded to the top surface of the bearing frame 1. The design of the infusion rack that can move together with the bearing frame ensures that during the movement of the patient, the infusion treatment can be carried out continuously and stably without interruption or repositioning of the infusion equipment, thus improving the continuity and safety of the treatment. Secondly, the integrated design of the infusion rack and the bearing frame 1 simplifies the operation process of medical equipment, reduces the workload of medical staff, and improves the efficiency and quality of the overall medical service.

[0080] Embodiment 5:

[0081] As shown in the attached Figure 2 figure, the difference from Embodiment 4 is that a fixing rack is welded to the outer wall of the bearing frame 1 close to the display window 20. The fixing rack is used to place and fix an oxygen cylinder. The design of the fixing rack enables medical staff to quickly and conveniently access the oxygen cylinder during the transportation of the patient or the completion of rehabilitation exercises, reducing the steps of searching for, fixing, and connecting the oxygen source, thus realizing the function of being able to respond to sudden emergencies and improving the safety of the patient.

[0082] In addition, a call bell is inlaid on one side of the inner wall of the movable cavity 102. The call bell is signal-connected to the medical care system of the inpatient department. Through the call bell, the patient can independently and quickly convey their discomfort or needs, ensuring that medical staff can respond immediately and reducing potential risks caused by poor communication or delays.

[0083] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
