Description

Technical Field

[0001] The present invention relates to the technical field of medical device transport equipment, and in particular to an ECMO transport equipment adapted for a hospital bed. Background Art

[0002] In the existing transportation of medical equipment, especially ECMO devices, which contain precision components and are extremely sensitive to external vibrations and shocks, it is crucial to ensure their stability and safety during transportation.

[0003] Traditional fixing devices mostly use simple straps, hooks or mechanical clamping methods. Although these methods can complete basic fixing functions, they lack dynamic adaptability when the device needs to move or withstand external vibrations. They cannot adjust the clamping force in real time to cope with pressure changes, which can easily cause the device to shift, loosen or even be damaged. Especially when the device moves violently with the bed or transfer vehicle, external vibrations and inertial forces can significantly change the force distribution of the device, and the fixed clamping force cannot dynamically adapt to these changes. For example, in situations such as vibration or turning, the device will be displaced due to the action of inertial forces. If the clamping force of the fixing device is insufficient, the device will slide or even detach from the support plate, increasing the risk of device damage and posing a threat to the continuity of patient treatment. To address this situation, traditional fixing methods usually use a larger clamping force. However, in complex vibration scenarios, this fixing method can exert excessive pressure on the device's casing or internal precision components, causing unintended physical damage. Summary of the Invention

[0004] 1) Technical problems solved The present invention provides an ECMO transport device adapted to a hospital bed, which enables the ECMO device to flexibly follow the movement of the hospital bed and ensures the safety of the device during transport and operation.

[0005] 2) Technical solution To achieve the above-mentioned object, the present invention provides the following technical solution: an ECMO transport device adapted for a hospital bed, comprising: The device body for movement; The device body is provided with a locking mechanism for moving in a direction perpendicular to the horizontal plane, and the locking mechanism is used to clamp on the bed to fix the device body relative to the bed; and A clamping mechanism, wherein the device body is provided with at least one clamping mechanism for pivoting relative to the device body, the clamping mechanism being used for adaptively compensating and clamping the ECMO device and for moving in a direction perpendicular to a horizontal plane; The clamping mechanism includes at least two telescopic clamping devices, each of which is used to act simultaneously on at least two adjacent contact surfaces of the ECMO device, and each telescopic clamping device is provided with at least two clamping rods for performing translational motion respectively, and the movement axes of the two clamping rods located on the same telescopic clamping device are perpendicular to each other; Each clamping rod detects the contact pressure with the contact surface of the ECMO device in real time through the pressure detection unit configured thereon, and adjusts the movement of the clamping rod based on the feedback delay of the contact pressure through the control module. The control module compares the deviation of the contact pressure values ​​of any clamping rod detected in multiple times during the current detection stage with the preset target contact pressure range and the change trend of the contact pressure value, and comprehensively considers the cumulative movement of the clamping rod in the current detection stage. The control module delays the adjustment of the movement of the clamping rod in the next adjacent detection stage.

[0006] Furthermore, the control module adjusts the movement amount of the clamping rod based on the feedback delay of the contact pressure by, specifically, adjusting the clamping rod to move closer to the contact surface in the next adjacent detection phase when the statistical mean of the contact pressure values ​​detected in the current detection phase is lower than the preset target contact pressure range, and adjusting the movement amount according to the degree of deviation; When a statistical mean of contact pressure values ​​detected in the current detection phase is higher than the preset target contact pressure range, adjusting the clamping rod to move away from the contact surface in the next adjacent detection phase, and adjusting the movement amount according to the degree of deviation; At the same time, the movement strategy is dynamically adjusted according to the degree of change fluctuation of multiple contact pressure values ​​detected in the current detection stage. Among them, the movement amount of delayed adjustment when the change fluctuation is severe is lower than the movement amount of delayed adjustment when the change fluctuation is severe.

[0007] Furthermore, the device body is provided with at least one bracket for moving in a direction perpendicular to the horizontal plane, and the bracket also includes a turntable that can pivot relative to its own axis, and the clamping mechanism is fixed on the turntable.

[0008] The ECMO transfer device for adapting to a hospital bed according to claim 1 is characterized in that the clamping mechanism includes a support plate for receiving the ECMO device, at least two of the telescopic clamping devices are provided on the support plate, and the axis of the clamping rod on any one of the telescopic clamping devices is perpendicular to the axis of the clamping rod on the other telescopic clamping device.

[0009] Furthermore, the clamping mechanism includes at least two telescopic clamping devices, and there are two telescopic clamping devices as a group and symmetrically distributed on the telescopic clamping device. Each of the telescopic clamping devices has a first positioning surface and a second positioning surface perpendicular to each other. The first positioning surface and the second positioning surface each have at least one clamping rod, and each clamping rod is used to move toward the central axis of the telescopic clamping device.

[0010] Furthermore, at least two clamping rods are respectively provided on the first positioning surface and the second positioning surface of each telescopic clamping device, and the line connecting the axes of the two clamping rods respectively located on the two positioning surfaces is parallel to the horizontal plane.

[0011] Furthermore, when the ECMO device is placed on the support plate, each of the clamping rods on each of the telescopic clamping devices begins to perform translational motion toward the center of the support plate, thereby approaching the contact surface of the ECMO device; When the rod head of any clamping rod is in close contact with the contact surface of the ECMO device, the contact pressure value applied to the contact surface is detected at the rod head, and when the difference in the contact pressure values ​​is stable within a set threshold range within a set continuous time interval, the clamping rod stops its translational motion relative to the telescopic clamping device so that the difference continues to stabilize within the set threshold range.

[0012] Furthermore, when there is at least one contact pressure value detected by the clamping rod on each of the first positioning surface and the second positioning surface of the telescopic clamping device, and the difference in the contact pressure value detected by the clamping rod within a set continuous time interval is stable within the set threshold range, all the clamping rods on the telescopic clamping device stop making translational motion relative to the telescopic clamping device.

[0013] Furthermore, the turntable also includes a telescopic rod that can move in a direction perpendicular to the axis of the turntable, and the clamping mechanism is arranged on the telescopic rod.

[0014] 3) Beneficial effects: Compared with the prior art, this invention has the following beneficial effects: The present invention monitors the pressure on the contact surface between the clamping rod and the equipment in real time, and dynamically adjusts the movement distance of the next stage based on the pressure change trend and the movement amount of the clamping rod in the current detection stage. This compensation mechanism based on pressure detection feedback ensures that the clamping force is always in the optimal range, avoids the problem of being too loose or too tight, and effectively improves the fixation stability and safety of the equipment.

[0015] The multi-degree-of-freedom design of the clamping mechanism, including adjustment and movement in the vertical and horizontal directions, enables it to adapt to complex spatial environments, such as narrow wards or emergency transport vehicles. Through the combination of the turntable and the telescopic rod, it can meet the placement requirements of the equipment in different positions and angles, enhancing the flexible application capabilities in actual scenarios.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0019] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0020] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0021] Combine Figures 1 to 5 The figure shows an ECMO transport device for adapting to a hospital bed. This solution aims to provide an ECMO (extracorporeal membrane oxygenation) device with a transport device for adapting to a hospital bed, ensuring that the stability and transportation requirements of the ECMO device can be safely and conveniently supported during the movement and fixation on the bed.

[0022] Specifically, first of all, regarding the equipment body 10, it is the core part of the entire transfer equipment. Its design not only requires the ability to adapt to different types of beds, but also needs to maintain synchronous movement when the bed moves to ensure the overall stability of the ECMO device and equipment.

[0023] The movement characteristics of the device body 10 are mainly achieved by the movement rod 30 and the locking mechanism 40 provided on the device body 10 .

[0024] More specifically, the device body 10 is provided with at least one movable rod 30 capable of moving in a direction perpendicular to the horizontal plane. The movable rod 30 can be freely extended or adjusted in height to adapt to the height and structural characteristics of different types of hospital beds.

[0025] In some embodiments, one end of the travel rod 30 is fixedly connected to the device body 10, while the other end is hingedly connected to the locking mechanism 40. The vertical movement of the travel rod 30 allows the device body 10 to adapt to different bed heights and, with the cooperation of the locking mechanism 40, achieves a secure fixation to the bed.

[0026] Regarding the movable rod 30, it provides vertical adjustability for the device, allowing it to adapt to different bed heights and configurations. Furthermore, the adjustable position of the movable rod 30 provides more convenient space for the operation of the locking mechanism 40, ensuring easy docking of the device to the bed even in complex medical environments.

[0027] Regarding the locking mechanism 40, in some embodiments, the locking mechanism 40 is installed at the distal end of the movable rod 30 and adopts a clamping structure. The clamp is connected to the movable rod 30 by a hinged manner and can be flexibly rotated within a specific angle range to adapt to the edge structures of different beds.

[0028] In some application scenarios, you can refer to Figure 1 and Figure 5 The clamping claws are used to clamp the edge of the bed and firmly fix the device body 10 on the bed through the clamping force, so that the device body 10 is in a stationary state relative to the bed, avoiding displacement or sliding of the device during transportation.

[0029] When the clamping jaws are clamped on the edge of the bed, the vertical force applied downward by the moving rod 30 is converted into a clamping force on the edge of the bed through the hinge point of the clamping jaws, thereby achieving a firm fixation.

[0030] Furthermore, in some embodiments, the inner surface of the clamping jaws may be designed to be a soft material, such as a silicone or rubber coating, to increase friction and prevent damage to the bed structure.

[0031] In summary, it can be understood that the locking mechanism 40 secures the device body 10 to the bed as a single unit. Since the bed itself is wheeled, the design of the device body 10 ensures that it can move synchronously with the bed, eliminating the need for additional propulsion. This design reduces the operator's burden and avoids stability issues caused by asynchrony between the device and bed.

[0032] In addition, through the cooperation of the moving rod 30 and the locking mechanism 40, the device body 10 achieves flexible height adjustment and stable fixation.

[0033] Specifically, the design of the movable rod 30 and the articulated clamp for vertical movement enables the device to be compatible with various types of beds, including beds with different edge thicknesses or diverse frame materials, greatly improving its adaptability. In addition, the locking mechanism 40 ensures the relative stillness of the device and the bed by applying a clamping force to the bed through the clamp, especially during the bed transfer process, to prevent the device from shaking and affecting the operation of the ECMO device. In some embodiments, an articulated clamp is used, and the flexibility of its articulated structure allows the device to be quickly installed or disassembled, making it convenient for medical staff to switch the device between different beds. The height adjustment of the movable rod 30 also reduces the inconvenience during the device installation process.

[0034] It is understood that during emergency transport, patients need to be quickly moved to the operating room or ICU while using the ECMO device. By using this device, medical staff move the device body 10 to the side of the bed and adjust the height of the device by moving the rod 30 to align it with the edge of the bed. Then, the articulated clamping jaws automatically or manually clamp the edge of the bed to complete the fixation of the device to the bed.

[0035] Then, when the bed begins to move, the device body 10 is secured to the bed via the locking mechanism 40, allowing it to move synchronously with the bed. The stable grip of the jaws ensures that the device will not shift due to turns or bumps. Finally, the medical staff releases the locking mechanism 40, allowing the device to be easily removed from the bed and reattached as needed.

[0036] In summary, this design significantly improves the transport efficiency of ECMO equipment while ensuring the safety of patients and equipment. It is suitable for various emergency and ward switching scenarios within the hospital.

[0037] The clamping mechanism 20 in this device is a key component. Its core function is to safely position and securely clamp the ECMO device, while also providing flexible adjustment capabilities to accommodate ECMO devices of varying shapes and sizes. By combining the design of a telescopic clamping device 201, clamping rod 202, support plate, bracket 50, and turntable 501, the clamping mechanism 20 achieves multi-directional movement, flexible clamping, and precise positioning, ensuring stability and ease of operation of the ECMO device during transport.

[0038] In some embodiments of the present invention, the clamping mechanism 20 includes at least two telescopic clamping devices 201, each of which is used to install a clamping rod 202 and achieve precise positioning of the ECMO device through its position and angle adjustment functions, wherein the telescopic clamping device 201 is the basic structure of the clamping mechanism 20, which is used to connect and guide the movement of the clamping rod 202.

[0039] More specifically, each telescopic clamping device 201 is equipped with at least two clamping rods 202. These rods 202 can independently translate to adjust their contact position with the ECMO device. The axes of any two clamping rods 202 on the same telescopic clamping device 201 are perpendicular to each other. This orthogonal design enables the clamping mechanism to clamp and support the ECMO device from multiple directions, thereby providing stability. The clamping rods 202 on different telescopic clamping devices 201 also maintain perpendicular axes. This layout ensures that the clamping mechanism 20 can secure the ECMO device in all three dimensions.

[0040] In some embodiments, a pressure sensor is installed at the tip of each clamping rod 202 to detect contact pressure in real time. The delay compensation mechanism for the clamping rod 202 is designed to dynamically adjust the movement distance of the clamping rod 202 to adapt to pressure changes in fast-moving and vibrating scenarios, thereby achieving stable and precise clamping force control.

[0041] Specifically, in each detection stage, the clamping rod 202 collects the pressure value of the contact surface with the equipment in real time through the built-in pressure sensor, and the control system that controls the movement of each clamping rod 202 calculates the following key indicators.

[0042] The deviation (positive or negative) of multiple pressure values ​​from the target pressure range during the current detection phase; The degree of pressure fluctuation during the current detection phase, i.e. the amplitude and frequency of contact pressure changes; The movement amount of the clamping rod 202 in the current stage is used as a reference for adjustment in the next stage.

[0043] In combination with the above indicators, the moving distance of the clamping rod 202 in the next stage is predicted and adjusted.

[0044] More specifically, the adjustment logic for controlling the movement distance can be understood as follows: if the pressure value is above the target range (i.e., a positive deviation), the clamping force applied by the clamping rod 202 is too great, and the telescopic clamping device 201 will reduce the movement distance of the clamping rod 202 in the next phase. Conversely, if the pressure value is below the target range (i.e., a negative deviation), the movement distance is increased to gradually approach the target pressure range. The adjustment distance is positively correlated with the deviation; the larger the deviation, the greater the adjustment in the movement distance.

[0045] If the detected pressure fluctuation frequency is high, such as caused by vibration, the movement speed and adjustment range of the clamping rod 202 will be appropriately reduced in the next stage to avoid the state of the clamping rod 202 being unstable due to frequent movement. If the pressure fluctuation is small or tends to be stable, the movement adjustment will be carried out normally.

[0046] In some embodiments, regarding the control system, a PID controller can be used to process the feedback signal of the contact pressure. The PID controller can dynamically adjust the displacement of the clamping rod by calculating the error in real time, that is, the deviation between the actual contact pressure and the preset target pressure.

[0047] Regarding the delayed adjustment of the movement of the clamping rod 202 of the control system, it can be understood that after each detection stage, the telescopic clamping device 201 will wait for a short delay period to fully process the pressure feedback of the current stage and ensure that the movement adjustment of the clamping rod 202 does not conflict with the pressure acquisition process. The length of the delay period can be adjusted according to the actual scene requirements and the movement speed. For example, in a scene with a faster movement speed, it is used to shorten the delay period to improve the response efficiency, while in a more stable scene, it is used to extend the delay period to improve the movement accuracy.

[0048] In summary, it can be understood that the introduction of the delay compensation mechanism enables the telescopic clamping device 201 to maintain precise control of the clamping force in scenarios involving rapid movement or vibration, effectively reducing instability caused by frequent adjustments, and significantly improving the reliability and adaptability of the device's fixed position. Specifically, the telescopic clamping device 201 utilizes the delay compensation mechanism to prevent short-term pressure fluctuations caused by movement from interfering with the control of the clamping force. By delaying the adjustment of the clamping rod 202, it prevents excessive movement of the clamping rod 202 caused by high-frequency vibration, thereby maintaining the stability of the clamping state.

[0049] Regarding the support plate in the clamping mechanism 20, which supports the weight of the entire clamping mechanism 20 and the ECMO device, multiple telescopic clamping devices 201 are mounted on it. It is important to note that the overall structure of the support plate and the device has been optimized through strength calculations to ensure sufficient rigidity and stability even when supporting high-weight equipment.

[0050] Furthermore, in some embodiments, the layout of the telescopic clamping devices 201 on the support plate is carefully designed so that the axis of the clamping rod 202 on any telescopic clamping device 201 is perpendicular to the axis of the clamping rod 202 on another telescopic clamping device 201. This layout provides highly flexible clamping capabilities and can accommodate ECMO devices of different sizes and shapes.

[0051] More specifically, the bracket 50 is mounted on the movable rod 30 of the device body 10 and can move freely along the axis of the movable rod 30 to adjust the height of the clamping mechanism 20. The height adjustment function of the bracket 50 enables the device to adapt to the installation requirements of hospital beds of different heights and ECMO devices.

[0052] A pivoting turntable 501 is hingedly attached to the bracket 50. This turntable 501 is capable of rotating at various angles around the axis of the movable rod 30. The clamping mechanism 20 is secured to the turntable 501. The pivoting function of the turntable 501 allows the clamping mechanism 20 to adjust its angle to suit the installation orientation or operational requirements of the ECMO device. For example, the pivoting function of the turntable 501 can accommodate the need to tilt the ECMO device at a certain angle for operation or connection.

[0053] It should be noted that the height movement function of the bracket 50 combined with the angle adjustment function of the turntable 501 provides the clamping mechanism 20 with high flexibility, which can meet the installation and use requirements in various complex scenarios.

[0054] As can be appreciated, the clamping mechanism 20 achieves flexible, multi-directional movement through several key features. First, the free movement of the bracket 50 along the axis of the movable rod 30 enables the clamping mechanism 20 to adjust its position vertically. Second, the pivoting of the turntable 501 about the axis of the movable rod 30 provides the clamping mechanism 20 with multi-angle operation capabilities. Third, the independent translational movement of the clamping rod 202 on the telescopic clamping device 201 enables the clamping mechanism 20 to precisely adjust the clamping position, thereby accommodating ECMO devices of varying sizes and shapes.

[0055] Regarding the above-mentioned clamping mechanism 20, it can be understood that its multi-directional clamping design and real-time monitoring of the pressure sensor ensure the stability of the ECMO device during transportation and prevent the device from moving or loosening. In addition, the flexible design of the telescopic clamping device 201 and the clamping rod 202 enables the clamping mechanism 20 to adapt to ECMO devices of different models and sizes to meet the needs of different medical scenarios. The height adjustment function of the frame and the angle adjustment function of the turntable 501 make the clamping mechanism 20 more convenient during installation and use, reducing the operating burden of medical staff. Regarding the introduction of the pressure sensor, it provides real-time clamping force monitoring, which helps to prevent equipment damage or unstable fixation caused by excessive or insufficient clamping force.

[0056] For example, in the ICU ward, medical staff need to quickly install the ECMO device from the equipment storage area to the bedside and fix it. First, the medical staff adjusts the height of the clamping mechanism 20 by moving the rod 30 and rotates the turntable 501 to a suitable installation direction for the ECMO device. After that, the clamping rod 202 on the telescopic clamping device 201 is translated to the appropriate position of the ECMO device, and the clamping force is adjusted by the pressure sensor to ensure that it is firmly fixed. During the transportation process, the pressure sensor monitors the clamping status in real time to ensure the stability of the equipment. If the ECMO device needs to adjust the angle to cooperate with the operation, the turntable 501 is used to quickly rotate to the appropriate angle to meet clinical needs.

[0057] Regarding the more specific number and position of the telescopic clamping device 201 of the clamping mechanism 20, in some embodiments, reference is made to Figures 2 to 4 In the clamping mechanism 20, three telescopic clamping devices 201 are designed, two of which are evenly distributed at symmetrical positions on the support plate.

[0058] More specifically, two telescopic clamping devices 201 are arranged in pairs for fixing on the two sides of the ECMO device, and another telescopic clamping device 201 is used to fix the top of the ECMO device. This arrangement forms a symmetrical structure, which can ensure the uniform distribution of clamping force to the greatest extent and improve the stability and reliability of the equipment.

[0059] As described above, the structure and function of each telescopic clamping device 201 are exactly the same in design. The distribution of each telescopic clamping device 201 is coordinated with the symmetry of the support plate, so that the clamping mechanism 20 can not only provide stable support when clamping the ECMO device, but also adapt to the external contours of the device of different shapes.

[0060] In some embodiments, the telescopic clamping device 201 is designed as a double-sided structure, that is, each telescopic clamping device 201 includes two mutually perpendicular positioning surfaces, namely the first positioning surface 2011 and the second positioning surface 2012. The two positioning surfaces are respectively arranged on two adjacent planes of the telescopic clamping device 201, and maintain a vertical relationship between them.

[0061] Regarding the arrangement of the clamping rods 202 on the positioning surfaces, more specifically, at least two clamping rods 202 are provided on each positioning surface, and these clamping rods 202 can perform translational motion along the plane of the telescopic clamping device 201 .

[0062] The axis layout of the clamping rod 202 on the two positioning surfaces meets the following rules: The axis of the clamping rod 202 located on the first positioning surface 2011 is parallel to the horizontal plane; The axis of the clamping rod 202 located on the second positioning surface 2012 is also parallel to the horizontal plane; The axis connecting the clamping rods 202 on the two positioning surfaces is parallel to the horizontal plane, thereby ensuring that the clamping operation is performed in the same plane without affecting the stability of the support plate.

[0063] All clamping rods 202 can move toward the central axis of the telescopic clamping device 201, and their range of motion can adapt to different shapes and sizes of ECMO devices.

[0064] Regarding the clamping operation of the telescopic clamping device 201, more specifically, in some embodiments of the present invention, when the ECMO device is placed in the center area of ​​the support plate of the clamping mechanism 20, the clamping mechanism 20 begins to operate. The clamping rods 202 of each telescopic clamping device 201 move one by one toward the central axis until they contact the contact surface of the ECMO device. The force sensor at the head of the clamping rod 202 then begins to monitor the pressure applied to the contact surface in real time. During the contact process, the force sensor at the head of the clamping rod 202 detects the pressure value applied to the surface of the ECMO device. When the pressure value remains stable within the set time interval and the change value is lower than the threshold range, the system determines that the clamping rod 202 is in the optimal clamping state.

[0065] Once the clamping rod 202 reaches a stable state, its translational motion stops immediately to prevent damage to the device or operational errors caused by excessive clamping. In other words, the pressure sensor's monitoring function ensures flexible control during the clamping process, preventing excessive clamping force from damaging the device's contact surface. Once clamping is complete, the clamping rod 202 of the telescopic clamping device 201 firmly secures the ECMO device to the center of the support plate, providing stable support for subsequent operations.

[0066] It is understood that all clamping rods 202 of the telescopic clamping device 201 operate independently, but their movements are coordinated in real time by the control system to ensure that the force applied by each clamping rod 202 is evenly distributed across the surface of the ECMO device. This synchronized adjustment prevents deformation of the device due to excessive force at a single point and improves the stability of the entire clamping mechanism 20.

[0067] In summary, by utilizing at least one pair of symmetrically distributed telescopic clamping devices 201 and a strategically positioned clamping rod 202, the clamping mechanism 20 achieves uniform, multi-directional clamping, ensuring the stability of the ECMO device. The clamping rod 202 offers a wide range of motion, and the flexible design of the telescopic clamping device 201 accommodates ECMO devices of varying sizes. Furthermore, the real-time monitoring and feedback mechanism provided by the pressure sensor enhances the precision of the clamping process, reducing the burden on the operator.

[0068] For example, in the actual scenario of transporting an ECMO device, medical staff place the ECMO device in the center area of ​​the support plate. After starting the clamping mechanism 20, the clamping rod 202 automatically adjusts its position, gradually approaches the contact surface of the device and applies a uniform clamping force. When the device moves with the bed, the clamping rod 202 can firmly fix the ECMO device, and will not loosen even in the event of slight vibration or tilt. By adjusting the movement direction of the clamping rod 202 through the control system, the clamping mechanism 20 can quickly release the device, facilitating subsequent use and connection. This design not only improves the transport efficiency of the ECMO device, but also greatly reduces the risk during the operation of the device.

[0069] In addition, in order to ensure that the clamping operation of each telescopic clamping device 201 reaches a balanced state, and at the same time prevent individual clamping rods 202 from stopping movement too early or too late and affecting the overall clamping effect, in other embodiments of the present invention, the system is designed with an intelligent coordination mechanism based on pressure sensor monitoring feedback.

[0070] More specifically, the clamping rods 202 on each telescopic clamping device 201 are distributed on the first positioning surface 2011 and the second positioning surface 2012. The movement of these clamping rods 202 is monitored in real time by their respective pressure sensors. When the following conditions are met, all clamping rods 202 on the telescopic clamping device 201 stop translating.

[0071] Condition 1: The pressure value monitored by the pressure sensor of at least one clamping rod 202 on the first positioning surface 2011 remains stable within a set continuous time interval, and the change difference of the pressure value is less than a set threshold.

[0072] Condition 2: The pressure value monitored by the pressure sensor of at least one clamping rod 202 on the second positioning surface 2012 also satisfies the above conditions.

[0073] When the above two conditions are met at the same time, all the clamping rods 202 of the telescopic clamping device 201 stop moving. This design ensures that all the clamping rods 202 on the telescopic clamping device 201 work in coordination, preventing a single clamping rod 202 from stopping independently and causing the telescopic clamping device 201 to tilt or uneven force distribution.

[0074] Incorporating this condition into the embodiment, for example, during the startup phase, the ECMO device is placed in the center area of ​​the support plate, the clamping mechanism is activated, and the clamping rods 202 of the telescopic clamping device 201 begin to move one by one toward the central axis, gradually contacting the contact surface of the ECMO device. During the monitoring process, the pressure sensor begins to collect pressure data at the contact surface between the clamping rods 202 and the ECMO device. The system determines whether the pressure value changes remain stable within a threshold range for a set continuous time. Simultaneously, the clamping rods 202 on the second positioning surface 2012 also undergo the same monitoring and judgment process.

[0075] If the pressure values ​​of at least one clamping rod 202 on the first positioning surface 2011 and the second positioning surface 2012 meet the stability judgment conditions, the system triggers a stop signal, and all clamping rods 202 on the telescopic clamping device 201 immediately stop translating and maintain the existing clamping position.

[0076] It should be noted that the multiple telescopic clamping devices 201 operate independently of each other without direct interference, but the system will adjust the action sequence of the remaining telescopic clamping devices 201 according to the real-time feedback of the support plate to ensure uniform distribution of the overall clamping force.

[0077] Through the above-mentioned mechanism, the clamping mechanism realizes the coordinated stopping of the clamping rod 202 on each telescopic clamping device 201, avoiding the imbalance of the telescopic clamping device 201 caused by the independent stopping of a single clamping rod 202, thereby improving the overall stability of the clamping device. The real-time feedback monitored by the pressure sensor ensures that the force applied by the clamping rod 202 is not too large or too small, which can not only firmly fix the ECMO device but also not damage its contact surface. The synchronous judgment mechanism of the clamping rod 202 of the first positioning surface 2011 and the second positioning surface 2012 makes the force applied to the ECMO device by each telescopic clamping device 201 evenly distributed, reducing the risk of excessive local force. It can be understood that through the above-mentioned design, the clamping mechanism not only has strong clamping ability and adaptability, but also can demonstrate excellent stability and flexibility in a variety of actual scenarios, meeting the stringent requirements for the safe transportation of ECMO devices.

[0078] Finally, to further enhance the flexibility of the clamping mechanism 20 in various orientations and positions, a turntable 501 and telescopic rod combination is incorporated into the design. This allows the clamping mechanism 20 to pivot along the axis of the mobile rod 30, adjusting its angle to accommodate different ECMO device placement orientations. By moving perpendicular to the axis of the mobile rod 30, additional fore-and-aft adjustment is provided, enabling the clamping mechanism 20 to more precisely contact and secure the ECMO device.

[0079] More specifically, the turntable 501 is fixed on the moving rod 30 and is used to pivot around the axis of the moving rod 30. The pivot angle range can be adjusted as needed, usually ±90 degrees, to adapt to different installation orientations that the ECMO device may be used for.

[0080] The telescopic rod is arranged at the top of the turntable 501, and its axial direction is perpendicular to the axis of the moving rod 30. The telescopic rod can be driven by a motor or hydraulically controlled to achieve smooth telescopic movement. The clamping mechanism 20 is fixed to the free end of the telescopic rod and can achieve forward and backward displacement adjustment as the telescopic rod moves.

[0081] In summary, it can be understood that when the ECMO device is placed asymmetrically, the turntable 501 can adjust the angle of the clamping mechanism 20, and the telescopic rod further adjusts the position, thereby achieving stable clamping from different directions. Furthermore, when the ECMO device is placed asymmetrically, the turntable 501 can adjust the angle of the clamping mechanism 20, and the telescopic rod further adjusts the position, thereby achieving stable clamping from different directions. The displacement flexibility provided by the telescopic rod and the rotation capability of the turntable 501 allow the device to quickly adapt to ECMO devices of different specifications and shapes, meeting various clinical needs.

[0082] Through the combined design of telescopic rods and turntable 501, clamping mechanism 20 achieves flexible adjustment and precise fixation in three dimensions. Whether facing complex placement or dynamic transportation environments, this design provides an efficient, safe, and reliable clamping solution, significantly improving the device's applicability and ease of operation.
