Description

Technical Field

[0001] The utility model relates to the technical field of marine equipment, in particular to a marine active compensation medical bed. Background Art

[0002] With the in-depth development of marine science and technology and the growing demand for medical services at sea, the demand for stability of the internal environment, especially surgery and other medical procedures, has become increasingly prominent on both civilian and military ships. During long voyages, especially when encountering complex sea conditions or performing emergency rescue missions, a stable surgical environment is essential to ensure the success rate of medical treatment and the safety of patients' lives. The roll and pitch of the ship not only affect the daily rest of the crew, but for the medical team performing delicate operations on board, any slight shaking may interfere with the accuracy of the operation and increase the risk of surgery. For example, when performing medical operations such as ophthalmic surgery and neurosurgery that require extremely high stability and precision, even a slight swaying of the ship may cause irreversible damage or surgical failure. Utility Model Content

[0003] 1. Technical problems to be solved by the utility model

[0004] In view of the technical problems of inevitable shaking such as roll and pitch in the existing offshore medical environment, the utility model provides a ship-borne active compensation medical bed, which can provide a stable working plane for the complex working conditions on board and provide favorable environmental conditions when facing some special needs such as surgery.

[0005] 2. Technical solution

[0006] In order to solve the above problems, the technical solution provided by the utility model is:

[0007] A marine active compensation medical bed comprises a bed support frame forming a plane; an intermediate limit mechanism connected to the center of the bed support frame; a plurality of servo crank mechanisms which are arranged around the intermediate limit mechanism, wherein at least one servo crank mechanism is arranged on each side of the intermediate limit mechanism and a crank connector is lifted and connected to the bed support frame; and a control box which is provided with an inclinometer and a controller connected thereto, wherein the controller is electrically connected to the intermediate limit mechanism and the servo crank mechanism.

[0008] The bed support frame is the basic framework of the entire medical bed. It is responsible for providing a stable support structure, forming a plane space for carrying patients, and connecting with other mechanical components to ensure the overall strength and stability of the bed. The intermediate limit mechanism is located in the center of the bed support frame. Its main function is to serve as the core fulcrum of the entire dynamic compensation system. While limiting the excessive swing of the bed, it allows the servo crank mechanism to rotate around it in a controlled manner to adapt to the dynamic changes of the hull. The servo crank mechanism is a key dynamic compensation unit, which adopts multiple and is arranged around the intermediate limit mechanism. Each servo crank is equipped with a precision servo motor drive, which can realize the precise rotation of the crank and the lifting and lowering of the connector according to the controller instructions. The purpose of this design is to adjust the inclination and position of the bed surface synchronously by adjusting the activities of each crank when the ship is bumpy, so as to actively offset the shaking of the hull and maintain the stability of the bed surface. The crank connector is a key component that transmits the movement of the servo crank mechanism to the bed support frame. It enables the bed to fine-tune the height in the vertical direction or adjust the tilt angle in the horizontal direction through lifting and lowering movements, ensuring that the bed always maintains the best stability. The control box integrates electronic devices such as inclinometers and controllers, among which: Inclinometer: monitors the posture changes of the bed in real time, that is, the inclination angle of the bed surface relative to the horizontal plane, and feeds the data back to the controller. Controller: Based on the received inclination data, combined with the preset program and algorithm, calculates the necessary compensation actions, and controls the servo crank mechanism to perform corresponding adjustments to achieve the effect of actively compensating for the hull shaking. In general, these components work together to form an intelligent and automated compensation system that can provide patients on board with a stable treatment and rest environment similar to that of a hospital bed on land in a complex marine environment.

[0009] Optionally, the servo crank mechanism includes a servo motor, a reducer, a crank plate, a connecting rod and a crank connector, the servo motor is connected to the reducer, the output shaft of the reducer is fixed to the crank plate, the crank plate is rotatably connected to the connecting rod, and the connecting rod is movably connected to the crank connector.

[0010] The servo motor is a high-performance electric motor that can quickly respond to control signals and accurately control its own rotational position, speed and torque. In the marine active compensation medical bed, the servo motor receives the command signal from the controller, generates a driving torque, and realizes dynamic adjustment of the bed surface through precise control. The reducer is connected after the servo motor, mainly used to reduce the high-speed speed output by the servo motor and increase the torque, so as to convert the high-speed low-torque power into a low-speed high-torque power suitable for the crank mechanism. The reducer ensures that the servo crank mechanism has enough power and precise speed to adjust the position and inclination of the bed. The crank plate is where the output shaft of the reducer is fixed. It is a rotating part in the crank mechanism and rotates with the drive of the motor and reducer. The rotation angle of the crank plate directly affects the movement amplitude and direction of the connecting rod, and then adjusts the state of the bed. The connecting rod plays the role of transmitting and converting the form of motion in the crank mechanism. One end of it is rotatably connected to the crank plate through a joint or hinge, and the other end is movably connected to the crank connector. When the crank plate rotates, the connecting rod will extend or swing according to the principle of leverage, converting the rotational motion of the crank plate into linear or swinging motion on the bed support frame. The crank connector is a connecting component between the connecting rod and the bed support frame. It can move or rotate along a specific path, thereby further transmitting the motion transmitted by the connecting rod to the bed support frame. By lifting or translating the crank connector, the bed surface can be tilted up and down or forward and backward and left and right to offset the shaking of the hull and maintain the stability of the bed.

[0011] Optionally, the normal direction of the rotation plane of the crank rotating plate of each of the servo crank mechanisms is directed toward the intermediate limiting mechanism.

[0012] The normal direction of the rotating plane of the crank plate in each servo crank mechanism points to the middle limit mechanism. This means that the lifting and tilting actions of all servo crank mechanisms are carried out around a common center point, that is, the middle limit mechanism, and their movements will not generate forces that affect the structural stability in the radial direction of the middle limit mechanism, avoiding the middle limit mechanism from being broken, etc., and also ensuring that the compensation effect is centralized and effective.

[0013] Optionally, the intermediate limiting mechanism includes a telescopic component and a Hooke's hinge, wherein the telescopic component is provided with a telescopic shaft, wherein the telescopic shaft is axially rotationally connected to a connecting shaft, and the connecting shaft is connected to the Hooke's hinge.

[0014] The telescopic component is a sleeve component for guiding the telescopic shaft, which is slidably connected to the telescopic shaft, and the axial rotation of the telescopic shaft is not affected. The intermediate limit mechanism can limit the translation of the bed support frame on the XY axis plane, and the intermediate limit mechanism cooperates with the reinforcement frame to further limit the rotation of the bed support frame around the Z axis. The intermediate limit mechanism has the freedom of Z-axis lifting and rotation, which is sufficient to realize the up and down or front and back left and right tilt of the bed support frame to offset the shaking of the hull and maintain the stability of the bed.

[0015] Optionally, a reinforcing mechanism is provided on the center line of the bed support frame, a reinforcing connector of the reinforcing mechanism is movably connected to the bed support frame, and the reinforcing mechanism is movably connected to the bed support frame on the plane where the center line is located.

[0016] The reinforcing mechanism limits the rotation of the bed support frame and strengthens the resistance to lateral force, thereby improving the overall structural strength.

[0017] Optionally, the reinforcement mechanism includes a first bearing seat and a second bearing seat located in the same rotation plane, the second bearing seat is rotatably connected to a reinforcement frame, and a reinforcement connector is provided on the top of the reinforcement frame.

[0018] The reinforcing connector of the reinforcing mechanism can provide the bed support frame with the freedom to tilt and lift, but limits the freedom of left and right translation, thereby improving the strength of the bed support frame to cope with lateral stress.

[0019] Optionally, the intermediate limiting mechanism, the servo crank mechanism and the bottom of the control box are all connected to the base.

[0020] The base is used to provide structural support.

[0021] Optionally, movable wheels are provided under the base.

[0022] Mobile wheels make it easy to move. There are many scenes on the ship that require movement, so it is more convenient to set up mobile wheels.

[0023] 3. Beneficial effects

[0024] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0025] Enhanced stability: The intermediate limit mechanism ensures that the bed remains in a basically stable state when it is affected by waves, wind and other factors during the voyage of the ship, reducing patient discomfort and potential safety hazards caused by the hull shaking. Dynamic balance adjustment: The servo crank mechanism is distributed around the bed support frame, which can adjust the inclination angle and flatness of the bed surface in real time according to the dynamic changes of the ship, and offset the impact of the hull roll and pitch through the lifting and lowering movement of the crank connector, so that the patient is always in a comfortable environment close to the level. Precise control: The inclinometer built into the control box can monitor the inclination state of the bed in real time, cooperate with the controller to accurately calculate and drive the servo crank mechanism to work, and realize the active regulation of the bed surface posture, thereby effectively avoiding the adverse effects of severe shaking on the wound healing, treatment process and rest quality of the injured and sick. Improve medical efficiency: Since the bed can intelligently adapt to the marine environment, medical staff can perform medical operations such as injections, dressing changes, examinations, etc. under relatively stable conditions, improving the quality and efficiency of medical services. Reduce the risk of secondary injury: For patients who need strict position fixation, especially those with spinal injuries or fractures, the active compensation system can prevent secondary injuries caused by unnecessary position changes and ensure the patient's life safety.
