Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to a patient transport device for anesthesia. Background Technology

[0002] After surgery or during transfer to the intensive care unit (ICU), anesthetized patients are in a special physiological state characterized by loss of consciousness, muscle relaxation, and unstable vital signs. At this time, patients are extremely sensitive to changes in position; any violent shaking, tilting, or sliding can lead to serious complications such as endotracheal tube dislodgement, intravenous access dislodgement, intracranial pressure fluctuations, or even secondary spinal cord injury. Therefore, safe and smooth transfer is a crucial aspect of perioperative management.

[0003] Currently, the most commonly used transport devices in clinical practice are ordinary transport beds, which only have basic movement functions. Some high-end products have added functions such as electric lifting and guardrail locking, but they still rely on manual operation by medical staff. In recent years, with the development of smart medical technology, some intelligent transport beds have begun to introduce posture sensors and electric adjustment mechanisms, which can realize manual adjustment of the bed board level, improving the stability of transport to a certain extent, but there are still some obvious technical limitations.

[0004] Existing transport devices generally lack scene perception and control capabilities, failing to automatically identify different road transport scenarios. In complex scenarios, medical staff need to manually adjust device parameters and control the pushing force, which is cumbersome, relies on personnel experience, and is prone to delays, leading to problems such as bed tilting and vibration during scene transitions. Furthermore, the attitude adjustment and safety protection of existing devices are mostly controlled independently, unable to coordinately adjust parameters such as wheel damping, shock absorption stiffness, and fixing device status according to scenario requirements. This makes it difficult to achieve optimal stability across all scenarios, increasing the operational burden on medical staff and failing to completely eliminate safety risks during the transport of anesthetized patients.

[0005] Therefore, this invention proposes a patient transport device for anesthesia to reduce the workload of medical staff and improve the quality of medical care during transport. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a patient transport device for anesthesia, which reduces the workload of medical staff and improves the quality of medical care during transport.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: an anesthesia patient transport device, comprising a bed board, a bed frame, a controller, a sensing mechanism, an execution mechanism, and several wheels, wherein the sensing mechanism and the execution mechanism are both electrically connected to the controller; the sensing mechanism is used to acquire real-time transport environment and bed board status information.

[0008] The controller has multiple transfer scenario modes built-in, and identifies the current scenario based on the information transmitted by the sensing mechanism, and switches to the corresponding working mode based on the current scenario.

[0009] The actuator is used to receive instructions from the controller and coordinate the adjustment of the device's attitude and fixed state to adapt to different transportation scenarios.

[0010] The technical principles of the above solution are as follows:

[0011] The sensing mechanism monitors road obstacles and bed posture in real time and transmits the data to the controller. The controller has a built-in intelligent algorithm that automatically identifies scenarios such as flat ground, obstacle crossing, or slope and switches modes accordingly. After switching to the corresponding control mode, it sends instructions to the actuator to adjust the bed level, wheel damping, shock absorption stiffness, and other states in a coordinated manner. This ensures that the bed remains stable in different scenarios, avoids risks such as abnormal patient positioning and tube dislodgement, and reduces the operational burden on medical staff.

[0012] The above approach has the following beneficial effects:

[0013] 1. This solution, through real-time sensing and dynamic control, can maintain the stability of the bed in various transport scenarios, effectively avoid problems such as bed tilting and abnormal vibration, maintain the patient's proper position, reduce various transport-related safety risks, and provide reliable technical support for the patient's life safety during transport.

[0014] 2. This solution replaces a large number of manual operations by using scene recognition and posture adjustment. Medical staff do not need to frequently adjust the device status during transport, and can concentrate more on observing the patient's vital signs and handling emergencies, thereby reducing the workload of medical staff and improving the quality of medical care during transport.

[0015] 3. This solution can automatically identify the current transport scenario and quickly switch to the matching operating mode. It can adapt to the passage requirements of different scenarios without manual debugging, making the transport process smoother and reducing passage obstacles caused by scenario switching, effectively shortening the transport time and improving the overall efficiency of patient transport.

[0016] Furthermore, the actuator includes several damping components, and the bed frame is fixedly connected to the bottom of the bed board; several shock absorbers are symmetrically hinged on the bed frame, and a connecting arm is hinged to the end of each shock absorber away from the bed frame, and the rotating wheel is rotatably engaged with the connecting arm; one end of each damping component is fixedly connected to the bottom of the bed board, and the other end of each damping component is fixedly connected to the connecting arm.

[0017] Beneficial effects: The flexible and independent suspension constructed by the shock-absorbing frame and connecting arm, combined with damping components, forms a highly efficient shock absorption circuit. This structure not only improves the device's adaptability to complex road surfaces and ensures bed stability, but also avoids positional displacement and tubing risks caused by violent shaking of anesthetized patients, ensuring safe transport.

[0018] Furthermore, the sensing mechanism includes a road condition detector, which is electrically connected to the controller. When the road condition detector detects an obstacle on the road ahead, the controller switches to obstacle crossing mode and controls the corresponding damping components in the actuator to adjust the damping force in sequence, so that the bed board remains horizontal during the crossing process.

[0019] Beneficial effects: Obstacles are identified by road condition detectors, triggering obstacle crossing mode; the controller adjusts the damping force of each damping component according to the crossing sequence, actively compensating for the height difference of the wheel set, ensuring that the bed board always maintains a horizontal posture during bumps, preventing patients from sliding or being pulled by the tubing due to the pitch of the vehicle, and improving the stability and safety of transport under complex road conditions.

[0020] Furthermore, the damping component includes a damping sleeve, which is fixedly connected to the bottom of the bed plate. A sliding plate is slidably fitted on the inner wall of the damping sleeve. A push rod is fixedly connected to the bottom of the sliding plate, and the end of the push rod away from the damping sleeve is fixedly connected to the connecting arm. The damping sleeve is filled with magnetorheological fluid, and several guide holes are opened on the sliding plate. An excitation coil is also embedded in the side wall of the damping sleeve, and the excitation coil is electrically connected to the controller.

[0021] Beneficial effects: By utilizing the properties of magnetorheological fluid, the viscosity of the liquid can be adjusted in real time through the excitation coil current to achieve damping force regulation; compared with traditional mechanical shock absorption, it has a fast response speed and high control precision, can actively adapt to different road conditions and impacts, effectively absorb high-frequency vibrations, and provide a stable transport environment for anesthetized patients.

[0022] Furthermore, the actuator also includes several constraint straps set on both sides of the bed board, each of which is fixedly connected with a pull wire; the end of the pull wire away from the constraint strap is fixedly connected to the top rod.

[0023] Beneficial effects: By linking the displacement of the damping component with the restraint belt through the pull wire, the mechanical energy generated by road bumps is used to automatically tighten the restraint belt; this purely mechanical linkage has a rapid response and requires no additional power, achieving adaptive and stable restraint and improving transportation safety.

[0024] Furthermore, several piston cylinders are fixedly connected to the bottom of the bed board. Piston plates are slidably fitted on the inner walls of the piston cylinders. Movable rods are fixedly connected to the bottom of the piston plates. The end of the movable rod away from the piston plate is fixedly connected to the outer wall of the top rod.

[0025] The inner wall of the constraint band is also fixedly connected to a flexible layer. The side of the piston cylinder away from the movable rod is connected to a transmission pipe, and the end of the transmission pipe away from the piston cylinder is connected to the interior of the flexible layer.

[0026] Beneficial effects: The piston is driven by the displacement of the push rod, converting mechanical vibration into fluid pressure, which is synchronously injected into the flexible layer of the restraint belt through the transmission tube. During bumps, the contact area and wrapping pressure are automatically increased, which not only prevents the tube from falling off due to inertial sliding, but also avoids local pressure injuries by using flexible cushioning.

[0027] Furthermore, the sensing mechanism also includes an attitude sensor fixedly connected to the bed board, which is electrically connected to the controller. When the attitude sensor detects that the bed board is tilted, the controller switches to the ramp mode and controls the current of the excitation coil in the damping component at the corresponding position, causing the corresponding push rod to move. The controller also adjusts the pressure in the flexible layer of the corresponding area through the piston cylinder and the transmission pipe.

[0028] Beneficial effects: The tilt angle of the bed board is monitored in real time by the posture sensor, and the ramp mode is intelligently triggered; the controller adjusts the current of the specific damping component to drive the piston to directionally pressurize the flexible layer of the inclined side constraint belt, which increases stability, prevents patient displacement and tube traction, and ensures the stability and safety of the patient's position during ramp transfer.

[0029] Furthermore, it also includes an equipment platform, which integrates several quick interfaces, including power interfaces and air supply interfaces, for connecting life support equipment; the equipment platform is also equipped with a cable organizer for storing the equipment connection pipelines.

[0030] Beneficial effects: The integrated equipment platform and multi-functional quick-access interfaces enable plug-and-play life support equipment, shortening emergency preparation time. Dedicated cable organizers ensure proper cable management, preventing tangling, pulling, or detachment during transport. This design not only optimizes bed space but also ensures the continuity and stability of critical equipment such as respiratory and monitoring systems, improving emergency transport efficiency.

[0031] Furthermore, several side rails can be detachably attached to the top of the bed board.

[0032] Beneficial effects: The detachable side rail design balances protection and operational flexibility; this modular structure not only meets the safety requirements of different transport scenarios, but also improves the convenience and response speed of clinical emergency care.

[0033] Furthermore, each of the rotating wheels is equipped with an electromagnetic brake, which is electrically connected to the controller.

[0034] Beneficial effects: By linking the controller with the electromagnetic brake, automatic parking and emergency locking are achieved; the device is prevented from slipping unexpectedly; emergency braking is provided in case of emergencies to ensure the stability of the bed; and static stability and dynamic safety during transport are improved.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] The following detailed description illustrates the specific implementation method:

[0044] Example 1:

[0045] As attached Figures 1-4 As shown: An anesthesia patient transport device includes a bed board 1, a bed frame 2, a controller, a sensing mechanism, an execution mechanism, and several wheels 3. Both the sensing mechanism and the execution mechanism are electrically connected to the controller. The sensing mechanism is used to acquire real-time status information of the transport environment and the bed board 1. In some preferred embodiments, the bed board 1 can also adopt a segmented hinged design, enabling the device to meet the transport needs of different postures. Furthermore, an externally electrically driven telescopic component can be installed on the bed frame 2, allowing the bed board 1 to be adjusted to different heights to meet the needs of patients of different heights and body types.

[0046] The controller has multiple transport scenario modes built-in (such as obstacle crossing, uphill or docking), and identifies the current scenario based on the information transmitted by the sensing mechanism, and switches to the corresponding working mode (such as obstacle crossing mode, ramp mode or translation mode) based on the current scenario.

[0047] The actuator is used to receive instructions from the controller and coordinate the adjustment of the device's attitude and fixed state to adapt to different transportation scenarios.

[0048] The actuator includes several damping components. The bed frame 2 is bolted to the bottom of the bed board 1. Several shock absorbers 4 are symmetrically hinged on the bed frame 2. Each shock absorber 4 has a connecting arm 5 hinged to the end away from the bed frame 2. The rotating wheel 3 rotates with the connecting arm 5. One end of each damping component is fixedly connected to the bottom of the bed board 1 with screws, and the other end of each damping component is fixedly connected to the connecting arm 5 with bolts.

[0049] The sensing mechanism includes a road condition detector, which is electrically connected to the controller. When the road condition detector detects an obstacle on the road ahead, the controller switches to obstacle-crossing mode and controls the corresponding damping components in the actuator to adjust the damping force sequentially, so that the bed board 1 remains horizontal during the crossing process. In this embodiment, the road condition detector uses one or more of the following: a camera, an ultrasonic sensor, a lidar, and a millimeter-wave radar.

[0050] Combination Figure 3 As shown, the damping component includes a damping sleeve 6, which is bolted to the bottom of the bed plate 1. A sliding plate 7 is slidably fitted on the inner wall of the damping sleeve 6. A push rod 8 is screwed to the bottom of the sliding plate 7, and the end of the push rod 8 away from the damping sleeve 6 is screwed to the connecting arm 5. The inside of the damping sleeve 6 is filled with magnetorheological fluid, and several guide holes are opened on the sliding plate 7. An excitation coil 9 is also embedded in the side wall of the damping sleeve 6, and the excitation coil 9 is electrically connected to the controller.

[0051] The actuator also includes several constraint straps 10 disposed on both sides of the bed board 1, each constraint strap 10 having a pull wire fixedly sleeved on it; the end of the pull wire away from the constraint strap 10 is fixedly sleeved with the push rod 8. In this embodiment, the push rod 8 can pull the constraint strap 10 through the pull wire, so that it can tighten the constraint strap 10 through the pull wire during movement.

[0052] Several piston cylinders 11 are also fixedly connected to the bottom of the bed board 1 with screws. Piston plates 12 are slidably fitted on the inner wall of each piston cylinder 11. Movable rods 13 are fixedly connected to the bottom of each piston plate 12 with screws. The end of the movable rod 13 away from the piston plate 12 is fixedly connected to the outer wall of the top rod 8 with screws.

[0053] The inner wall of the constraint band 10 is also fixedly bonded with a flexible layer. The piston cylinder 11 is connected to a transmission pipe on the side away from the movable rod 13. The end of the transmission pipe away from the piston cylinder 11 is connected to the interior of the flexible layer.

[0054] The specific implementation process is as follows:

[0055] When the device is being pushed normally on a flat surface, the controller is in cruise mode; the excitation coils 9 in each damping component are supplied with basic current, the magnetorheological fluid maintains a low viscosity, and the sliding plate 7 can slide freely within the damping sleeve 6, allowing the suspension mechanism composed of the shock absorber frame 4 and the connecting arm 5 to absorb minor vibrations. At this time, the restraint belt 10 is in a comfortable tension state, with no additional pressure on the flexible layer inside the restraint belt 10, maintaining a close fit.

[0056] When the road condition detector detects an obstacle on the road ahead (such as a corridor joint or threshold), it immediately transmits a signal to the controller. The controller automatically switches to obstacle-crossing mode according to preset logic and sends timing control commands to the excitation coils 9 of each damping component.

[0057] Taking a single-sided front wheel encountering an obstacle as an example: When the front wheel is about to contact the obstacle, the controller sends a command to the excitation coil 9 at the corresponding position to change the viscosity of the magnetorheological fluid in the damping sleeve 6. At this time, the damping force corresponding to the front wheel decreases to facilitate easy lifting and crossing, while the damping force corresponding to the rear wheel increases to provide stable support. As the rotating wheel 3 moves upward through the linkage of the connecting arm 5 and the shock absorber 4, it drives the push rod 8 to slide within the damping sleeve 6, adjusting the fluid flow resistance through the guide hole to ensure that the bed plate 1 remains horizontal when the single-sided wheel assembly is lifted. After crossing, the current of each damping component is restored.

[0058] During the movement of the aforementioned damping component, the extension and retraction displacement of the push rod 8 simultaneously triggers the following two fixing and strengthening mechanisms:

[0059] When the push rod 8 moves upward, it is pulled upward through the connecting cable, which in turn pulls the restraint strap 10. This tightens the restraint strap 10, creating a more secure wrap around the patient's body. The greater the compression of the push rod 8 (i.e., the higher the obstacle), the stronger the tension of the restraint strap 10, resulting in a more secure fixation effect where the greater the bumps and the greater the displacement of the push rod 8, the higher the tension of the restraint strap 10.

[0060] As the push rod 8 moves upward, it drives the connected movable rod 13 and piston plate 12 to slide within the piston cylinder 11. When the push rod 8 moves upward, the piston plate 12 moves towards the bottom of the piston cylinder 11, compressing the fluid inside the cylinder. The fluid is then forced through the transmission pipe into the flexible layer inside the restraint band 10, causing it to expand uniformly. The expanded flexible layer applies a wider range of contact pressure to the patient's body, further enhancing the fixation effect. When the push rod 8 returns to its original position, the piston plate 12 retracts, the fluid in the flexible layer flows back, and the pressure is released.

[0061] This embodiment utilizes the intelligent linkage of perception, decision-making, and execution, and actively adjusts the damping distribution by leveraging the response characteristics of magnetorheological fluid to ensure that the bed board 1 maintains a horizontal posture in complex scenarios such as obstacle crossings and slopes. A dual linkage mechanism of mechanical cable and fluid transmission is established to convert road vibration energy into adaptive wrapping pressure of the restraint belt 10, which effectively prevents the tubes from falling off due to inertial slippage of anesthetized patients and avoids pressure injuries caused by rigid restraints. Combined with automatic parking and an integrated equipment platform, it improves the stability of transport, patient safety, and efficiency of emergency operations.

[0062] Example 2:

[0063] The difference from Embodiment 1 is that the sensing mechanism also includes an attitude sensor fixedly connected to the bed board 1 by screws, and the attitude sensor is electrically connected to the controller; when the attitude sensor detects that the bed board 1 is in a tilted state, the controller switches to the ramp mode; and controls the current of the excitation coil 9 in the damping component at the corresponding position, so that the corresponding push rod 8 is displaced; and adjusts the pressure in the flexible layer of the corresponding area through the piston cylinder 11 and the transmission pipe. In this embodiment, the attitude sensor is an inertial measurement unit (IMU).

[0064] The specific implementation process is as follows:

[0065] When the transport device travels to a slope section, the attitude sensor fixed on the bed board 1 monitors the tilt angle data in real time and transmits it to the controller. Once the tilt angle exceeds a preset threshold, the controller switches to slope mode. At this time, the controller outputs a differentiated current to the excitation coil 9 at a specific position according to the tilt direction, which increases the viscosity of the magnetorheological fluid in the corresponding damping sleeve 6, forming a locking effect to limit the displacement of the push rod 8, thereby maintaining the horizontal posture of the bed board 1 and preventing hemodynamic fluctuations caused by the patient's bed pitching.

[0066] Simultaneously, the controlled displacement linkage rod 8 pushes the piston plate 12 to compress the fluid medium, and the pressure is directionally delivered to the flexible layer through the transmission tube, causing it to expand and fit tightly against the patient's body, increasing frictional resistance. This synchronous linkage mechanism effectively prevents the risk of tubing traction caused by the anesthetized patient sliding, and avoids the risk of pressure sores caused by rigid restraint throughout the process, without relying on manual intervention, until the device leaves the slope and returns to a horizontal position, at which point the protection is released.

[0067] Example 3:

[0068] The difference from Embodiment 2 is that this embodiment also includes a device platform, which integrates several quick interfaces, including a power interface and a gas source interface. The quick interfaces are used to connect life support equipment. The device platform is also equipped with a cable organizer for storing the equipment connection pipelines.

[0069] The specific implementation process is as follows: During the transport preparation stage, medical staff place life support equipment such as ventilators and monitors directly on the equipment platform. There is no need to find external sockets or gas cylinders. They only need to align the plugs and air tubes of the equipment with the quick power interface and quick gas interface on the platform to complete the locking connection, connect the power and oxygen supply, and shorten the loading time of emergency equipment.

[0070] Subsequently, excess connecting wires and oxygen tubing from the equipment are neatly inserted into the cable organizer slots on the edge of the platform. The organizer's flexible structure neatly organizes and secures the messy cables, preventing them from falling to the ground and being crushed or tangled by the rotating wheel 3. During transport, even encountering bumps or sharp turns, the quick-connect self-locking mechanism ensures that the connection remains secure, and that power and gas supply are uninterrupted. The cable organizer keeps the tubing neat and orderly at all times, eliminating the risk of equipment displacement or patient tubing dislodgement due to cable pulling. This allows medical staff to focus on patient observation rather than equipment management.

[0071] Example 4:

[0072] As attached Figure 4 As shown, the difference from Embodiment 3 is that the top of the bed board 1 can also be detachably connected with several side guardrails 14.

[0073] The specific implementation process is as follows: A detachable side rail design is adopted, balancing protection and operational flexibility. During installation, it forms a closed protective space, effectively preventing anesthetized patients from falling off the bed due to unconscious agitation or shifting position; after removal, the bed surface is completely open, facilitating rapid emergency resuscitation procedures such as cardiopulmonary resuscitation and endotracheal intubation by medical staff, or facilitating bed transfers. This modular structure not only meets the safety requirements of different transport scenarios but also improves the convenience and response speed of clinical emergency care.

[0074] Example 5:

[0075] The difference from Embodiment 4 is that each of the rotating wheels 3 is also equipped with an electromagnetic brake, and the electromagnetic brake is electrically connected to the controller.

[0076] The specific implementation process is as follows: During the transfer process, the electromagnetic brake and the controller maintain real-time communication. When the device needs to be temporarily stopped (such as waiting for the elevator or performing bedside operations), medical staff only need to press the pause button, and the controller will immediately send an energizing signal to the electromagnetic brakes of all the rotating wheels 3. The friction pads inside the brakes press against the wheel hubs to achieve parking and prevent the device from accidentally slipping on smooth ground or slight slopes.

[0077] If the sensing mechanism detects a sudden emergency (such as a risk of severe collision or a sudden change in the patient's vital signs requiring immediate braking), the controller will trigger the emergency braking logic, forcing all electromagnetic brakes to lock the rotating wheel 3 at maximum power, ensuring the bed remains stable. Furthermore, when the device is in ramp mode and the attitude sensor detects an excessive tilt angle, the controller will automatically preload electromagnetic braking force as a second line of defense in the damping system, providing double protection for patient safety. Once a command to continue pushing is received, the electromagnetic brakes are immediately de-energized and released, allowing the rotating wheel 3 to resume free rotation, achieving an intelligent switch from dynamic movement to static locking.

[0078] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
