Description

Technical Field

[0001] This utility model relates to the field of medical transport bed technology, and in particular to a medical electric transport bed with lifting guardrail. Background Technology

[0002] In the field of medical care, electric medical transport beds are key equipment in patient transfer, examination, and treatment processes. Their safety and ease of operation directly affect the efficiency of medical and nursing work and patient comfort. Among these components, the guardrails, as a core component ensuring patient transport safety, must have reliable height adjustment functions to adapt to the protection needs of patients of different body types, while also facilitating bedside nursing procedures for medical staff. A new type of electric medical transport bed with adjustable guardrails aims to improve the safety performance and ease of use of the equipment by optimizing the guardrail lifting structure and locking mechanism, meeting the diverse needs of clinical transport scenarios.

[0003] In existing technologies, the lifting and lowering of guardrails on medical transport beds mostly employ hydraulic drive or screw drive structures. Hydraulically driven guardrails use a hydraulic pump to power a piston rod, causing it to extend and retract, thus raising and lowering the guardrail. Locking relies on the shut-off function of a hydraulic valve. Screw drive guardrails, on the other hand, use a motor to drive a screw rod to rotate, causing the nut and guardrail body to move along the screw rod's axial direction. Locking is achieved through a motor brake or a mechanical nut self-locking mechanism. Both of these structures require an external power source and complex transmission components to achieve height adjustment and position fixation of the guardrail.

[0004] However, the operation of raising and lowering guardrails in existing technologies is often cumbersome, requiring the use of multiple buttons or levers to complete raising, lowering, and locking. Furthermore, after frequent use, problems such as hydraulic leakage and screw jamming are prone to occur, resulting in unstable locking and potential safety hazards such as accidental lowering of the guardrail. This affects patient transport safety and the efficiency of medical operations. Therefore, a medical electric transport bed with a raising guardrail is proposed to solve the above problems.

[0019] Reference Figures 1-4 This utility model provides an embodiment of a medical electric transport bed with a lifting guardrail, including a lifting base 1. The lifting base 1 supports the weight of all components above it and can adjust the overall height through a built-in scissor lift mechanism, model SJB-0.5, to adapt to different transport scenarios. Further details are omitted here. A bed board 2 is provided on the upper surface of the lifting base 1. The bed board 2 supports the patient's body and is waterproof, corrosion-resistant, and lightweight, preventing pressure sores caused by prolonged lying down. A guardrail body 3 is provided on the side wall of the bed board 2. The guardrail body 3 prevents the patient from rolling over during transport, providing safety protection. A lifting component is provided on the side wall of the lifting base 1. The lifting component drives the guardrail body 3 to adjust the height. A fixing component is provided on the side wall of the guardrail body 3. The fixing component clamps the infusion tubes, oxygen tubes, and other tubing on the patient to prevent them from shaking and falling off during transport. The lifting assembly includes a fixed plate 8 and multiple rotating plates 9. The side wall of the fixed plate 8 is fixedly connected to the side wall of the bed board 2, providing a stable rotation fulcrum for the rotating plates 9. The side walls of the multiple rotating plates 9 are rotatably connected to the side wall of the fixed plate 8. The multiple rotating plates 9 are connected end to end in sequence to form a scissor-type telescopic structure, which works in conjunction with the guardrail body 3 to perform lifting and lowering movements, achieving the effect of smooth lifting and lowering of the guardrail through mechanical linkage. A sliding rod 10 is slidably connected inside the guardrail body 3. The sliding rod 10 is used to transmit unlocking power and push subsequent components to complete the locking and unlocking of the guardrail. A connecting plate 11 is fixedly connected to one end of the sliding rod 10. The connecting plate 11 is a rectangular steel plate. A rotating bar 12 is rotatably connected to the side wall of the connecting plate 11. An insert rod 13 is slidably connected inside the guardrail body 3. The insert rod 13 is used to lock the height of the guardrail. A fixed rod 15 is fixedly connected inside the guardrail body 3. The fixed rod 15 is used to provide sliding guidance for the insert rod 13 and prevent the insert rod 13 from deviating when sliding. A spring 16 is sleeved on the side wall of the fixed rod 15. One end of spring 16 is fixedly connected to the inside of the guardrail body 3, and the other end of spring 16 is fixedly connected to the side wall of the insert rod 13. Spring 16 is used to provide a return force for the insert rod 13, pushing the insert rod 13 to automatically insert into the sleeve 14 to complete the locking. One end of the rotating plate 9 is rotatably connected to the side wall of the guardrail body 3, and together with the fixed plate 8 and other rotating plates 9, it forms a complete telescopic transmission chain. One end of the rotating bar 12 is rotatably connected to the side wall of the insert rod 13, and together with the connecting plate 11 and the sliding rod 10, it forms an unlocking mechanism, achieving the effect of pressing the sliding rod. The movable rod 10 can quickly release the guardrail from locking; the inner wall of the insert rod 13 is slidably connected to the side wall of the fixed rod 15, ensuring that the insert rod 13 slides along a fixed trajectory and avoids misalignment when locking; the side wall of the end rotating plate 9 is fixedly connected to the sleeve 14, which is used to cooperate with the insert rod 13 to form a locking structure. The side wall of the insert rod 13 is slidably connected to the inside of the sleeve 14. Through the insertion and extraction of the insert rod 13 and the sleeve 14, the height of the guardrail can be locked and unlocked, achieving the effect of convenient manual raising and lowering of the guardrail and stable locking; The bed board 2 is internally connected to an electric slide rail 4, which is a VM-120 silent electric slide rail, used to provide power for patient transfer. The electric slide rail 4 is internally connected to a sliding frame 5, which is an aluminum alloy frame structure. The sliding frame 5 is internally connected to a rotating track 6, which is used to contact the patient's body and, in conjunction with the electric slide rail 4 and the sliding frame 5, performs horizontal transport movement. This achieves the effect of transferring the patient from the hospital bed to the transport bed without manual handling by medical staff, reducing the physical exertion of medical staff and avoiding friction injury to the patient's body. The side wall of the bed board 2 is fixedly connected to a suspension rod 7, which is used to suspend medical auxiliary equipment such as infusion bags and drainage bags, ensuring that the height of the equipment is adapted to the patient's position during transport and preventing the tubing from being pulled due to improper equipment suspension.

[0020] Reference Figure 1 and Figure 5The fixing components include a fixing seat 17 and a clamp 18. The side wall guardrail of the fixing seat 17 is slidably connected to the side wall of the guardrail body 3, and is used to flexibly adjust the position on the guardrail body 3 to adapt to the fixing needs of different patients' tubes. The clamp 18 is made of medical-grade silicone material. The clamp 18 is used to directly clamp the patient's infusion tubes, oxygen tubes and other tubes. Due to its soft and elastic material properties, it can avoid wear on the tubes, and can also fit tightly to tubes of different diameters to achieve a stable clamping effect. A fixing block 19 is fixedly connected to the side wall of the jacket 18, and a second spring 20 is provided on the side wall of the fixing seat 17. One end of the second spring 20 is fixedly connected to the side wall of the fixing seat 17, and the other end of the second spring 20 is fixedly connected to the side wall of the fixing block 19. This is used to provide elastic clamping force for the jacket 18. When the pipeline is placed into the clamping cavity of the jacket 18, the second spring 20 resets and pulls the jacket 18 to close, thus achieving the effect of continuously and stably clamping the pipeline and preventing the pipeline from shaking and falling off during transportation. A sliding block 21 is fixedly connected to the side wall of the fixed seat 17. The side wall of the sliding block 21 is slidably connected to the inside of the guardrail body 3 through a T-shaped slide rail. It works in conjunction with the guardrail body 3 to adjust its position, so that the fixed seat 17 can slide smoothly along the guardrail. A locking block 22 is slidably connected inside the sliding block 21. The side wall of the locking block 22 is slidably connected inside the guardrail body 3. It is used to lock the position of the fixed seat 17 after it is adjusted to the target position. A spring 23 is provided inside the sliding block 21. One end of the spring 23 is fixedly connected inside the sliding block 21, and the other end of the spring 23 is fixedly connected to the side wall of the locking block 22. It is used to provide outward elastic force to the locking block 22, push the locking block 22 to automatically extend and lock into the slot of the guardrail body 3, so as to achieve the effect of conveniently and stably locking the position of the fixed seat 17.

[0021] Working principle: When the device is in use, when the patient needs to be transferred, the electric slide rail 4 is activated, which drives the sliding frame 5 to move the rotating track 6 under the patient. When the rotating track 6 rotates, it can gently move the patient's body along the bed board 2, reducing the physical exertion of medical staff to manually move the patient and avoiding friction injury to the patient's body.

[0022] When the guardrail needs to be raised, the guardrail drive rotating plate 9 is manually pushed to rotate around the connection point. The rotation of the rotating plate 9 causes the guardrail body 3 to move upward. When lowering, the rotating plate 9 is rotated in the opposite direction, and the guardrail body 3 moves downward accordingly. When the guardrail body 3 is adjusted to the target height, the spring 16 pushes the insertion rod 13 to slide along the side wall of the fixed rod 15, so that one end of the insertion rod 13 is inserted into the sleeve 14 on the end rotating plate 9. The cooperation between the insertion rod 13 and the sleeve 14 restricts the rotational freedom of the rotating plate 9, thereby locking the height of the guardrail body 3. If it is necessary to unlock and adjust, the sliding rod 10 is pressed to push the connecting plate 11 to slide, which drives the rotating bar 12 to rotate, thereby pulling the insertion rod 13 upward, compressing the spring 16, and causing the insertion rod 13 to disengage from the sleeve 14. At this time, the rotating plate 9 can rotate again to realize the height adjustment of the guardrail.

[0023] The fixing seat 17 is slidably connected to the side wall of the guardrail body 3 via the sliding block 21. Its position can be adjusted along the length of the guardrail body 3 to accommodate different pipeline fixing requirements. In the initial state, the spring 3 23 pushes the locking block 22 out of the sliding block 21 and inserts it into a pre-set slot on the side wall of the guardrail body 3, locking the position of the fixing seat 17. If the position of the fixing seat 17 needs to be adjusted, the sliding block 21 is pushed to press the locking block 22, compressing the spring 3 23 and causing the locking block 22 to disengage from the slot of the guardrail body 3. At this point, the fixing seat 17 can be pushed to slide along the guardrail until the target position is reached, after which it is released. The locking block 22 and spring 3 23 reset and push the locking block 22 back into the slot to complete the position locking. The sleeve 18 is rotatably connected inside the fixed seat 17 and is used to directly clamp the pipeline. In the initial state, spring 20 is in the natural state and drives the clamping end of the sleeve 18 to close. When fixing the pipeline, the sleeve 18 is rotated outward, which drives the fixed block 19 to stretch spring 20 and put the pipeline into the clamping cavity of the sleeve 18. After the sleeve 18 is released, spring 20 resets and pulls the sleeve 18 to close, clamping the pipeline through the contact of the inner wall of the sleeve 18 to prevent the pipeline from shaking during transportation.
