Description

Technical Field

[0001] This invention relates to the field of transport beds, specifically a cardiology nursing transport bed. Background Technology

[0002] The Department of Cardiology, also known as the Department of Cardiovascular Medicine, is a core clinical department in the hospital that focuses on the diagnosis, treatment, and nursing of cardiovascular diseases. It mainly provides medical services for diseases related to the heart and blood vessels (including arteries, veins, and capillaries), and its scope of diagnosis and treatment covers a variety of common and critical diseases such as coronary heart disease, heart failure, arrhythmia, hypertension, cardiomyopathy, congenital heart disease, valvular heart disease, and aortic dissection.

[0003] Cardiology patients often present with sudden onset, critical condition, and fluctuating symptoms, requiring frequent transfers between wards, examination rooms, and operating rooms. Existing transport beds are poorly compatible with ward beds and examination beds, and most lack dedicated transfer connection structures. When receiving patients, multiple medical staff are required to work together, directly lifting the patient from their original bed to the transport bed by hand. During the transfer, limb traction and sudden changes in body position may cause a sudden increase or decrease in venous return in cardiology patients, inducing arrhythmias, blood pressure fluctuations, and even exacerbating heart failure symptoms. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a cardiology nursing transport bed, which solves the problem of requiring multiple medical staff to work together when receiving patients, allowing patients to be lifted directly from their original beds to the transport bed by human effort.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A cardiology nursing transport bed includes a base frame, a support frame at the upper end of the base frame, a support plate fixedly connected to the middle of the inner wall of the support frame, a reinforcing rod fixedly connected to the front end of the support frame near the support plate, a fixing plate at the upper end of the support plate, a head plate rotatably connected to the front end of the fixing plate, a leg plate rotatably connected to the rear end of the fixing plate, a mounting frame fixedly connected to the middle of the lower end of the fixing plate, a mounting plate fixedly connected to the front end of the mounting frame, a mounting groove formed in the middle of the upper surface of the mounting plate, a servo motor fixedly connected to the front end of the inner wall of the mounting groove, a screw fixedly connected to the output end of the servo motor, a threaded sleeve connected to the outer wall of the screw, hinged rods hinged to both sides of the upper surface of the threaded sleeve, and an electric push rod hinged to the middle of the outer wall of the rear end of the mounting frame, the output end of the electric push rod rotatably connected to the lower end of the leg plate.

[0007] The support plate is rotatably connected to a rotating column, and the lower end of the rotating column is fixedly connected to a connecting frame. The middle of the outer wall of the rear end of the reinforcing rod is rotatably connected to an electric push rod II, and the output end of the electric push rod II is rotatably connected to the connecting frame.

[0008] Both ends of the upper surface of the base frame are rotatably connected to cam frames. A fixing rod is fixedly connected to one side of the outer wall of the cam frame. A connecting rod is fixedly connected to both sides of the outer wall of the cam frame. A connecting rod is rotatably connected to both sides of the front and rear ends of the inner wall of the bracket. A synchronous electric actuator is rotatably connected to both sides of the middle part of the inner wall of the base frame. The output ends of the synchronous electric actuators are rotatably connected to the connecting rods.

[0009] Through the above technical solution, the cam frame, connecting rod, and connecting rod are driven by synchronous electric push rods. Combined with the structural cooperation between the cam frame and the fixed rod, the bed can be raised and lowered stably and can be accurately matched to the height of ward beds, examination beds, etc. With the synergistic effect of servo motors, screws, threaded sleeves, hinge rods, and auxiliary rotating rods, the headboard angle can be adjusted smoothly and accurately. Electric push rod one enables flexible adjustment of the legboard to form a sitting position. Electric push rod two drives the entire bed to rotate through the connecting frame and rotating column, which greatly reduces the physical burden and operational risks for nursing staff when transferring patients.

[0010] Furthermore, each of the four corners of the lower surface of the base frame is fixedly connected with a movable wheel;

[0011] The above technical solution, with its four corner wheels, ensures that the bed can be easily turned and pushed in spaces such as wards and corridors, greatly improving transport efficiency.

[0012] Furthermore, the front and rear ends of the outer wall of the bracket are fixedly connected to protective plates. A PLC control panel is provided on one side of the front outer wall of the protective plate. The PLC control panel is connected to the servo motor, electric push rod one, electric push rod two and synchronous electric push rod respectively.

[0013] The advantage of using the PLC control panel through the above technical solution is that it enables centralized, one-button intelligent control of all electric functions, including lifting, positioning, and rotation.

[0014] Furthermore, side guard plates are fixedly connected to both sides of the outer wall of the fixed plate;

[0015] The above technical solution effectively prevents patients from accidentally falling off the bedside during changes in position or transfers using side panels.

[0016] Furthermore, a rotating seat is fixedly connected to the lower end of the mounting bracket, and the lower end of the rotating seat is fixedly connected to the upper end of the rotating column.

[0017] The above technical solution ensures that the bed rotates smoothly and steadily when driven by the electric push rod, thus avoiding shaking or jamming.

[0018] Furthermore, guide grooves are provided on both sides of the upper surface of the mounting plate, and guide rods are fixedly connected to both ends of the inner wall of the guide grooves. Sliding sleeves are slidably connected to the outer walls of the guide rods. Auxiliary rotating rods are rotatably connected to both sides of the upper surface of the sliding sleeves. The upper ends of the auxiliary rotating rods and the hinge rods are rotatably connected to the lower end of the head plate.

[0019] Through the above technical solution, the cooperation between the guide rod and the sliding sleeve constrains the movement trajectory of the hinge rod, ensuring that the headboard moves smoothly and without shaking when it is raised under the drive of the servo motor. This avoids discomfort to the patient's head and neck due to sudden or unstable movements, and improves the comfort and safety of body position adjustment.

[0020] Furthermore, both connecting rods on both sides are rotatably connected to the connecting rod by a rotating shaft;

[0021] The above technical solution uses a rotating shaft to hinge the connecting rod to the connecting rod, so that the cam frame and connecting rod on both sides can move in a coordinated manner under the drive of the synchronous electric push rod.

[0022] This invention provides a cardiology nursing transport bed. It has the following beneficial effects:

[0023] This invention provides a cardiology nursing transport bed. It utilizes a synchronous electric actuator to drive a cam frame, connecting rod, and connecting rotating rod in a coordinated manner. Combined with the structural cooperation between the cam frame and the fixed rod, it achieves stable lifting and lowering of the bed, precisely matching the height of ward beds, examination beds, etc. With the synergistic action of a servo motor, screw, threaded sleeve, hinged rod, and auxiliary rotating rod, the headboard angle can be smoothly and precisely adjusted. One electric actuator allows for flexible adjustment of the leg rest to achieve a sitting posture, while another electric actuator, through the connecting frame and rotating column, drives the entire bed to rotate, greatly reducing the physical burden and operational risks for nursing staff when transferring patients.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example:

[0037] like Figure 1-9As shown, this embodiment of the invention provides a cardiology nursing transport bed, including a base frame 1. A support 12 is provided at the upper end of the base frame 1. A support plate 15 is fixedly connected to the middle of the inner wall of the support 12. A reinforcing rod 16 is fixedly connected to the front end of the support 12 near the support plate 15. A fixing plate 2 is provided at the upper end of the support plate 15. A head plate 21 is rotatably connected to the front end of the fixing plate 2. A leg plate 22 is rotatably connected to the rear end of the fixing plate 2. A mounting frame 24 is fixedly connected to the middle of the lower end of the fixing plate 2. The front end of the mounting frame 24 is fixedly connected to... A mounting plate 26 is attached, and a mounting groove 27 is provided in the middle of the upper surface of the mounting plate 26. A servo motor 28 is fixedly connected to the front end of the inner wall of the mounting groove 27. A screw 29 is fixedly connected to the output end of the servo motor 28. A threaded sleeve 210 is threadedly connected to the outer wall of the screw 29. Hinged rods 211 are hinged to both sides of the upper surface of the threaded sleeve 210. An electric push rod 216 is hinged to the middle of the outer wall of the rear end of the mounting bracket 24. The output end of the electric push rod 216 is rotatably connected to the lower end of the leg plate 22.

[0038] The support plate 15 is rotatably connected to a rotating column 31. The lower end of the rotating column 31 is fixedly connected to a connecting frame 32. The middle part of the outer wall of the rear end of the reinforcing rod 16 is rotatably connected to an electric push rod 3. The output end of the electric push rod 3 is rotatably connected to the connecting frame 32.

[0039] Cam frames 41 are rotatably connected to both ends of the upper surface of the base frame 1. A fixing rod 42 is fixedly connected to one side of the outer wall of the cam frame 41. A connecting rod 43 is fixedly connected to both sides of the outer wall of the cam frame 41. A connecting rod 45 is rotatably connected to both sides of the front and rear ends of the inner wall of the bracket 12. A synchronous electric push rod 4 is rotatably connected to both sides of the middle part of the inner wall of the base frame 1. The output end of the synchronous electric push rod 4 is rotatably connected to the connecting rod 43.

[0040] The synchronous electric push rod 4 drives the cam frame 41, connecting rod 43, and connecting rod 45 in linkage. Combined with the structural cooperation between the cam frame 41 and the fixed rod 42, the bed can be stably raised and lowered and can be accurately matched to the height of ward beds, examination beds, etc. With the synergistic effect of the servo motor 28, screw 29, threaded sleeve 210, hinge rod 211 and auxiliary rod 215, the headboard 21 angle can be adjusted smoothly and accurately. The electric push rod 1 216 enables flexible adjustment of the legboard 22 to form a sitting position. The electric push rod 2 3 drives the entire bed to rotate through the connecting frame 32 and rotating column 31, which greatly reduces the physical burden and operational risks of nursing staff when transferring patients.

[0041] Each of the four corners of the lower surface of the base frame 1 is fixedly connected with a movable wheel 11;

[0042] The four corner wheels ensure that the bed can be easily turned and pushed in spaces such as wards and corridors, greatly improving the efficiency of transport.

[0043] The front and rear ends of the bracket 12 are fixedly connected to the protective plate 13. A PLC control panel 14 is provided on one side of the front outer wall of the front protective plate 13. The PLC control panel 14 is connected to the servo motor 28, electric push rod 1 216, electric push rod 2 3 and synchronous electric push rod 4 respectively.

[0044] The advantage of using the PLC control panel 14 is that it enables centralized, one-button intelligent control of all electric functions, including lifting, positioning, and rotation.

[0045] Side guard plates 23 are fixedly connected to both sides of the outer wall of the fixed plate 2;

[0046] The side guard plate 23 can effectively prevent patients from accidentally falling off the side of the bed during changes in position or transfer.

[0047] The lower end of the mounting bracket 24 is fixedly connected to a rotating seat 25, and the lower end of the rotating seat 25 is fixedly connected to the upper end of the rotating column 31.

[0048] The rotating seat 25 ensures that the bed rotates smoothly and steadily when driven by the electric push rod 23, avoiding shaking or jamming.

[0049] Guide grooves 212 are provided on both sides of the upper surface of the mounting plate 26. Guide rods 213 are fixedly connected to both ends of the inner wall of the guide grooves 212. Sliding sleeves 214 are slidably connected to the outer wall of the guide rods 213. Auxiliary rotating rods 215 are rotatably connected to both sides of the upper surface of the sliding sleeves 214. The upper ends of the auxiliary rotating rods 215 and the hinge rods 211 are rotatably connected to the lower end of the head plate 21.

[0050] The cooperation between the guide rod 213 and the sliding sleeve 214 constrains the movement trajectory of the hinge rod 211, ensuring that the headplate 21 moves smoothly and without shaking when it is lifted by the servo motor 28, avoiding discomfort to the patient's head and neck due to sudden or unstable movement, and improving the comfort and safety of body position adjustment.

[0051] Both connecting rods 43 are rotatably connected to the connecting rod 45 by the rotating shaft 44;

[0052] The connecting rod 43 is hinged to the connecting rod 45 by the rotating shaft 44, so that the cam frame 41 on both sides and the connecting rod 43 can move in a coordinated manner under the drive of the synchronous electric push rod 4.

[0053] Working principle: First, the bed is moved to the target position by the casters 11 at the bottom of the base frame 1; then, the synchronous electric actuator 4 is activated, and its output end pushes the connecting rod 43, causing the cam rotating frame 41 to rotate around the connection point on the base frame 1. Through the linkage between the fixed rod 42 and the connecting rotating rod 45, the support 12 and the entire upper structure are driven to rise and fall smoothly until the bed surface matches the height of the target hospital bed; then, the servo motor 28 is activated by operating the PLC control panel 14, which drives the screw 29 to rotate, causing the threaded sleeve 210 to move axially along the screw 29, driving the hinged rods 211 on both sides and the auxiliary rotating rod 215 to move. The lower end of the auxiliary rotating rod 215 is guided by the sliding sleeve 214 sliding along the guide rod 213, thereby smoothly and accurately raising the headboard 21 to the target position. The angle is adjusted by controlling the extension and retraction of electric push rod 216 to raise the leg plate 22, making it easier to move the whole unit out later. Then, electric push rod 23 is activated, and its output end pushes or pulls the connecting frame 32, causing the rotating column 31 to rotate within the support plate 15. This, in turn, causes the mounting frame 24 and the entire bed surface above it, including the fixed plate 2, headboard 21, and leg plate 22, to rotate outward through the rotating seat 25. Then, the servo motor 28 and electric push rod 216 are activated again to adjust the appropriate angle. Finally, the patient is smoothly transferred to the surface. Then, electric push rod 23 extends and retracts, causing the whole unit to rotate to the surface. With the help of servo motor 28 and electric push rod 216, the patient is laid flat, greatly reducing the physical burden on nursing staff when transferring patients.
