Description

Technical Field

[0001] This utility model specifically relates to an emergency nursing transport device, belonging to the field of emergency equipment technology. Background Technology

[0002] An emergency nursing transport device is a specialized mobile device that enables the safe and efficient transfer of patients at the emergency scene, between ambulances and hospitals, and between different departments within a hospital. It integrates the functions of a stretcher, trolley, and hospital bed, which can significantly shorten transfer time and improve emergency response efficiency.

[0003] Existing emergency nursing transport devices typically use manual lifting or a sliding board method to transfer patients to examination beds or operating tables. Medical staff need to directly contact the patient's shoulders, back, waist, hips, and lower limbs. For patients with pelvic fractures, multiple rib fractures, or spinal injuries, the pulling, twisting, and suspension movements during the transfer can easily cause displacement of the fracture ends or even puncture nearby blood vessels and nerves. Emergency nursing transport devices that primarily use a "sliding board-lifting" or "sheet-dragging" method require the sheet to be pre-inserted under the patient, and the sheet's support is poor, leaving the pelvis and spine still subjected to bending stress. This cannot eliminate secondary mechanical stimulation to the traumatic area. While a single bed board can be lifted as a whole, it requires bending over to unlock multiple buckles, a cumbersome process that is unsuitable for emergency transport. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an emergency nursing transport device to solve the problems mentioned in the background section.

[0005] An emergency nursing transport device includes a bed frame and bed frames fixed to the left and right sides of the bed frame. A transport mechanism is supported on the bed frames, and the transport mechanism includes: A transfer frame is placed horizontally on the top surface of the two side bed frames, and a lifting rod is fixed at the head and tail ends of the transfer frame. A locking element, which is rotatably connected to the corresponding lifting rod; A limiting structure is slidably installed along the lifting rod and can cooperate with the bed frame on the same side to limit the longitudinal and lateral movement of the transfer frame on the bed frame.

[0006] Furthermore, each of the left and right sides of the transfer frame is provided with a foldable guardrail. The guardrail can be folded down or raised up by a vertical pivot at a 90-degree angle, and can be locked in the raised position.

[0007] Furthermore, both ends of the lifting rod are provided with sliding grooves along the axial direction, and the sliding grooves are through grooves with the groove openings facing downwards.

[0008] Furthermore, the locking element includes: A rotating ring is sleeved around the outer periphery of the lifting rod and rotatably connected thereto. A coil spring is provided between the inner wall of the rotating ring and the lifting rod, and the coil spring provides the torque to return the rotating ring to its original position. The hook head is fixed to the outer periphery of the rotating ring and is used to hook and pull the limiting structure to keep it in a disengaged state. A lever, fixed to the opposite side of the hook head, is used to manually drive the rotating ring to release the hook pull.

[0009] Furthermore, the limiting structure includes: A grip, which is arranged parallel to the lifting rod; A limiting head, which is fixed to both ends of the grip and extends downward; A slider, which is fixed to the limiting head and slidably fitted in a corresponding sliding groove; A spring is placed in the sliding groove, with one end abutting against the slider and the other end abutting against the end wall of the sliding groove, for pressing the limiting head against the bed frame.

[0010] Furthermore, each end of the bed frame is provided with a plug hole corresponding to the position of the limiting head. The limiting head is inserted into the plug hole under the action of the spring to achieve longitudinal and lateral limiting.

[0011] Furthermore, the top surface of the bed frame is fixed with longitudinally arranged protrusions, which slide in engagement with the inner side of the frame of the transfer frame to guide the transfer frame to be quickly positioned. A plurality of parallel rolling rods are rotatably supported between the two bed frames. The outer periphery of the rolling rods makes rolling contact with the bottom of the transfer frame to reduce lateral pushing and pulling resistance. Beneficial effects

[0012] This invention utilizes a sliding support and limiting insertion mechanism between the transport frame and the bed frame, enabling the transport frame to lock or unlock within seconds, facilitating the overall transport of the patient and avoiding secondary traction on fractured or injured areas. The limiting structure, under the action of a spring, maintains a constant pressure engagement with the insertion hole, eliminating longitudinal and lateral degrees of freedom and ensuring no displacement due to bumps or sudden stops during emergency transport. The exposed ends of the lifting rod form rigid handles, allowing multiple people to lift simultaneously, shortening transport time. The rolling rod converts sliding friction into rolling friction, allowing a single person to push in or pull out the transport frame, reducing operational intensity. The locking mechanism utilizes a coil spring for reset, enabling single-handed unlocking and relocking, meeting the dual requirements of speed and reliability in emergency situations. The overall structure requires no additional power source, and disassembly and assembly are tool-free, improving emergency efficiency and reducing equipment maintenance costs.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-8 As shown, an emergency nursing transport device includes a bed frame 1 and bed frames 2 fixed to the left and right sides of the bed frame 1. A transport mechanism is placed on the bed frames 2, and the transport mechanism includes: The transfer frame 6 is placed horizontally on the top surface of the two side bed frames 2, and the head and tail ends of the transfer frame 6 are each fixed with a lifting rod 8. A locking element, which is rotatably connected to the corresponding lifting rod 8; A limiting structure is provided, which is slidably installed along the lifting rod 8 and can be limited in conjunction with the bed frame 2 on the same side, to restrict the longitudinal and lateral movement of the transfer frame 6 on the bed frame 2.

[0017] In this embodiment, the transfer frame 6 rests directly on the top surface of the bed frame 2 via two lifting rods 8, forming a sliding support relationship that can be quickly pushed in or pulled out. The locking member rotates freely on the lifting rods 8. When the limiting structure is completely disengaged from the bed frame 2 and the sliding distance is at its maximum, the locking member immediately presses against the limiting structure, keeping the limiting structure detached from the bed frame 2. When the limiting structure is connected to the bed frame 2, it ensures a rigid connection between the transfer frame 6 and the bed frame 2, preventing longitudinal movement or lateral displacement due to bumps or sudden stops during emergency transport. The limiting structure slides along the lifting rods 8, with its lower end always tending towards the bed frame 2. Upon insertion, it immediately blocks any degree of freedom in any direction, ensuring... The patient, along with the transport frame 6, is stably positioned on the bed frame 1. The exposed ends of the lifting rods 8 provide gripping space for emergency personnel, facilitating rapid lifting in narrow passages or elevators. The easy disassembly of the transport frame 6 from the bed frame 2 allows for lifting the transport frame 6, along with the mattress and fixation straps, when the patient has a fracture that is difficult to directly handle, avoiding secondary traction or twisting of the injured area and achieving injury reduction. After disassembly, the lifting rods 8 on both sides of the transport frame 6 form rigid handles, allowing multiple rescuers to lift the patient smoothly, reducing bumps during transport, lowering the risk of fracture displacement, and shortening transport time, thus gaining valuable time for subsequent emergency care.

[0018] Please see Figures 1-4 As shown, as a technical optimization of this utility model, the transfer frame 6 is provided with a foldable guardrail 7 on each of its left and right sides. The guardrail 7 can be folded down or raised up by a vertical pivot at a 90-degree angle, and can be locked in the raised position.

[0019] In this embodiment, the guardrail 7 is hinged to the side of the transfer frame 6 via a vertical pivot. After flipping upwards by 90 degrees, it automatically fits into the frame of the transfer frame 6 and is then locked into the corresponding notch by a locking tongue to form a rigid support, preventing unconscious or agitated patients from sliding sideways. After flipping downwards by 90 degrees, the guardrail 7 is attached to the outside of the transfer frame 6, with a height lower than the bottom edge of the mattress, making it convenient for emergency personnel to perform chest compressions or quickly move the patient up and down. The entire opening and closing process can be operated with one hand, meeting the immediate needs of emergency scene for passage width and operating space.

[0020] Please see Figures 1-6 As shown, as a technical optimization of this utility model, both ends of the lifting rod 8 are provided with sliding grooves 9 along the axial direction. The sliding grooves 9 are through grooves with the groove opening facing downward.

[0021] In this embodiment, the sliding groove 9 extends inward along the axis from the end face of the lifting rod 8. The downward arrangement of the groove opening allows dust and liquid to fall off naturally under the action of gravity, keeping the groove clean. The through structure provides a bidirectional sliding stroke of equal length for the limiting structure, ensuring that the limiting head 15 can obtain the same guide length and support stiffness when inserted into the insertion hole 4 on the bed frame 2 from either side.

[0022] Please see Figures 1-7 As shown, as a technical optimization of this utility model, the locking member includes: A rotating ring 10 is sleeved on the outer periphery of the lifting rod 8 and rotatably connected thereto. A coil spring 11 is provided between the inner wall of the rotating ring 10 and the lifting rod 8. The coil spring 11 provides the torque to return the rotating ring 10 to its original position. Hook 12, which is fixed to the outer periphery of the rotating ring 10, is used to hook and pull the limiting structure to keep it in a disengaged state; A lever 13 is fixed to the opposite side of the hook head 12 and is used to manually drive the rotating ring 10 to rotate to release the hook pull state.

[0023] In this embodiment, the rotating ring 10 is fitted around the outer periphery of the lifting rod 8 with a clearance fit. The two ends of the coil spring 11 are respectively inserted into the radial holes preset in the inner wall of the rotating ring 10 and the rod surface, and always store the reset torque. When the emergency personnel press down the lever 13, the rotating ring 10 rotates against the torque of the coil spring 11, and the hook head 12 is lifted accordingly, keeping the limiting structure in place. After the lever 13 is released, the coil spring 11 immediately rebounds, and the hook head 12 is automatically released, waiting for the next locking, completing a quick unlocking and relocking with one hand, which meets the dual requirements of operation speed and reliability in emergency transport.

[0024] Please see Figures 1-8 As shown, as a technical optimization of this utility model, the limiting structure includes: A grip 14 is provided, which is arranged parallel to the lifting rod 8. Limiting head 15, the limiting head 15 is fixed to both ends of the grip 14 and extends downward; Slider 16, which is fixed to the limiting head 15 and slidably engaged in the corresponding sliding groove 9; Spring 17 is placed in the sliding groove 9, with one end abutting against the slider 16 and the other end abutting against the end wall of the sliding groove 9, for pressing the limiting head 15 against the bed frame 2.

[0025] In this embodiment, the handle 14 and the lifting handle 8 are kept parallel and at a constant distance, allowing the emergency responder to move the limiting heads 15 at both ends up and down simultaneously with a single hand grip; the slider 16 enters the sliding groove 9 along with the limiting head 15 and is guided by the groove wall, so that the limiting head 15 always inserts into or exits the insertion hole 4 on the bed frame 2 in a vertical direction, avoiding deflection and jamming; the spring 17 continuously applies sliding force to ensure that the limiting head 15 remains tightly fitted with the matching hole even when the vehicle stops suddenly, bumps, or tilts, thereby achieving rapid locking and reliable positioning between the transfer frame 6 and the bed frame 1, meeting the simultaneous needs of convenient operation and safety at the emergency scene.

[0026] Please see Figures 1-8As shown, as a technical optimization of this utility model, each end of the bed frame 2 is provided with a plug hole 4 corresponding to the position of the limiting head 15. The limiting head 15 is inserted into the plug hole 4 under the action of the spring 17 to achieve longitudinal and lateral limiting.

[0027] In this embodiment, the insertion hole 4 is located at both ends of the bed frame 2 and coaxially corresponds to the limiting head 15. The hole depth is slightly greater than the insertion length of the limiting head 15, so that the limiting head 15 is completely sunk to the bottom of the hole under the continuous pushing of the spring 17. The hole wall forms a rigid block for the limiting head 15 in four directions: front, back, left, and right, thereby simultaneously locking the longitudinal sliding and lateral swing of the transfer frame 6. When the vehicle brakes suddenly or the road surface is uneven, the end face of the insertion hole 4 abuts against the shoulder of the limiting head 15, and the impact force is directly transmitted to the bed frame 1 through the bed frame 2, preventing any visible displacement of the transfer frame 6 and ensuring a smooth and reliable emergency transfer process.

[0028] Please see Figures 1-4 As shown, as a technical optimization of this utility model, the top surface of the bed frame 2 is fixed with a longitudinally arranged protrusion 5, which slides with the inner side of the frame of the transfer frame 6 to guide the transfer frame 6 to be quickly positioned. A number of parallel rolling rods 3 are rotatably supported between the two bed frames 2. The outer periphery of the rolling rods 3 rolls in contact with the bottom of the transfer frame 6 to reduce the resistance to lateral pushing and pulling.

[0029] In this embodiment, the protrusion 5 is fixed along the longitudinal length to the outer side of the top surface of the bed frame 2. A guide groove is formed between the two protrusions 5. The guide groove maintains a sliding gap with the inner side of the frame of the transfer frame 6. When pushed in, the protrusion 5 first guides the frame, so that the transfer frame 6 is automatically aligned in the horizontal plane to avoid deviation and collision. The rolling rod 3 is arranged parallel between the two sides of the bed frame 2 and its outer periphery is slightly higher than the top surface of the bed frame 2. The bottom of the transfer frame 6 falls directly on the rolling rod 3. During the pushing or pulling process, the rolling rod 3 rotates accordingly, converting sliding friction into rolling friction, which significantly reduces the lateral operating resistance. Emergency personnel can quickly complete the loading and unloading under single-person operation, while reducing the wear of the top surface of the bed frame 2 and maintaining long-term positioning accuracy. After the limiting structure at both ends locks the grip rod 14, when the limiting head 15 disengages from the insertion hole 4, medical personnel can easily push the transfer frame 6 laterally.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
