Description

Technical Field

[0001] This utility model relates to transport beds, and more particularly to a convenient medical transport bed. Background Technology

[0002] A transport bed is a common medical tool, typically used for patient transport. It is convenient and widely used. Existing transport beds usually consist of a bed board, bed frame, and casters. The transport process requires first moving the patient from their original bed to the transport bed, then medical staff push the transport bed to the designated location before transferring the patient to the correct bed. However, for patients in a deep coma or with severe injuries, transferring them from their original bed to the transport bed, or vice versa, is difficult. Furthermore, the fixed, non-adjustable bed board of existing transport beds increases the risk of secondary injury during patient transport and also increases the workload of medical staff. Utility Model Content

[0003] This utility model provides a convenient medical transport bed, the main purpose of which is to solve the problems of inconvenient transportation and excessive weight of existing transport flatcars.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A user-friendly medical transport bed includes a bed frame, a main bed board, two side bed boards, and an adjustable lifting mechanism. The bottom of the adjustable lifting mechanism is installed inside the bed frame, the main bed board is installed on the top of the adjustable lifting mechanism, the two side bed boards are respectively hinged to the left and right sides of the main bed board, and the bottom of the two side bed boards are slidably supported and connected to the bed frame. Four universal casters with brakes are evenly distributed on the bottom of the bed frame.

[0006] The bed frame is equipped with guide bars on the top of the front and rear sides, and the bottom ends of the guide bars pass through the main bed board and are fixedly connected to the bed frame.

[0007] Both sides of the bed board have horizontal support blocks at the bottom front and rear. The bottom of each horizontal support block has an arc-shaped groove with an opening facing downwards. The arc-shaped groove is arranged to the left and right. Both sides of the top of the bed frame have two side support rods. The top of each side support rod has a spherical protrusion. The arc-shaped groove and the spherical protrusion can be slidably connected to each other to the left and right.

[0008] The adjustable lifting mechanism includes a lifting base, a screw, two drive sliders, and two support rods. The lifting base is installed in the middle of the inner side of the bed frame. The screw is installed on the top of the lifting base in a front-to-back direction. Both drive sliders are provided with internal threads. The internal threads of the two drive sliders are opposite and spaced apart in front and back on the screw. The lower ends of the two support rods are respectively hinged to the top of the corresponding two drive sliders. The tops of the two support rods are both hinged to the bottom of the main bed board.

[0009] The top of the lifting base is provided with a slide rail slider assembly, which includes a slide rail and two movable sliders. The slide rail is installed on the top of the lifting base and located below the screw. Both sliders are movably installed on the slide rail, and the tops of the two movable sliders are respectively installed on the bottoms of the two corresponding drive sliders.

[0010] An adjustment handle is installed at the front end of the screw.

[0011] The front end of the screw is connected to a drive motor, which is mounted on the lifting base. The bed frame is equipped with a motor driver and a motor adjustment panel.

[0012] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: This utility model is convenient to use and ingeniously designed. It features an adjustable lifting mechanism, a main bed board, and side bed boards. The main bed board's height is controlled by adjusting the adjustable lifting mechanism. When severely injured or deeply comatose patients need to be transferred from the bed to a transport bed, the main bed board is lowered by adjusting the adjustable lifting mechanism, so that both side bed boards are tilted inwards. The transport bed is then moved to the outside of the hospital bed, so the patient can easily slide from the edge of the side bed board to the main bed board simply by pushing them to the edge of the transport bed, achieving the transfer without excessive turning or moving. When it is necessary to move the patient from the transport bed to the hospital bed, the main bed board is raised by adjusting the adjustable lifting mechanism, so that both side bed boards are tilted outwards. The transport bed is then moved to the side of the hospital bed, so the patient can slide along the side bed board to the hospital bed simply by pushing them to the side bed board. This achieves easy transfer, eliminating the need for excessive turning during patient transport and avoiding secondary injury to the patient. It is also equipped with four casters, which allows medical staff to easily push the transfer bed, making it more convenient to use and effectively reducing the workload of medical staff.

[0017] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings.

[0018] Example 1:

[0019] Reference Figures 1 to 3 A user-friendly medical transport bed includes a bed frame 1, a main bed board 2, two side bed boards 3, and an adjustable lifting mechanism 4. The bottom of the adjustable lifting mechanism 4 is installed inside the bed frame 1. Multiple ventilation holes can be provided on the main bed board 2, which can be made of iron or wood. The main bed board 2 is mounted on top of the adjustable lifting mechanism 4. The two side bed boards 3 are respectively hinged to the left and right sides of the main bed board 2, with hinges providing greater convenience. The bottoms of both side bed boards 3 are slidably supported and connected to the bed frame 1. Guide rods 5 are provided on the top of the front and rear sides of the bed frame 1. The bottom ends of the guide rods 5 pass through the main bed board 2 and are fixedly connected to the bed frame 1. Four universal casters 6 with brakes are evenly distributed on the bottom of the bed frame 1.

[0020] Reference Figures 1 to 3 The bed frame 1 provides support and load-bearing capacity. The main bed board 2 is connected to an adjustable lifting mechanism 4, which controls the height of the main bed board 2, allowing it to be higher or lower than the side bed boards 3. The side bed boards 3 provide auxiliary support and can tilt during patient movement to or from the transport bed, facilitating easier patient movement. When the adjustable lifting mechanism 4 is adjusted, causing the main bed board 2 to tilt inwards along with the side bed boards 3, the patient is less likely to roll off the transport bed, providing safety protection. A guide bar guides the main bed board 2 as it rises or falls, and its upper part rests on the main bed board 2, preventing the patient from detaching from the main bed board 2 or being bumped by external personnel, thus providing safety protection. The omnidirectional casters 6 with brakes make it easier for medical staff to push the transport bed, and when the casters 6 are braked, the transport bed will not wobble or move.

[0021] Reference Figure 1 and Figure 3The bottom front and rear sides of the two side bed boards 3 are provided with transverse support blocks 7. The bottom of each transverse support block 7 is provided with an arc-shaped groove segment 8 with its opening facing downwards. The arc-shaped groove segment 8 is arranged to the left and right. The top sides of the bed frame 1 are provided with two side support rods 9. The top of each side support rod 9 is provided with a spherical protrusion 10. The arc-shaped groove segment 8 and the spherical protrusion 10 can be slidably connected to each other to the left and right.

[0022] Reference Figure 1 and Figure 3 The transverse support block 7 supports the side bed board 3. The arc-shaped groove 8, larger than a hemisphere, ensures that when connected to the spherical protrusion 10, the protrusion 10 remains engaged within the groove 8 and does not detach. The side bed board 3 can be moved by tilting downwards or upwards, and the side support rod 9 supports it, ensuring safety during patient transfer.

[0023] Reference Figure 1 and Figure 3 The adjustable lifting mechanism 4 includes a lifting base 41, a screw 42, two drive sliders 43, and two supporting inclined rods 44. The lifting base 41 is installed in the middle of the inner side of the bed frame 1. The screw 42 is installed on the top of the lifting base 41 in a front-to-back direction. Both drive sliders 43 have internal threads, and the internal threads of the two drive sliders 43 are opposite and spaced apart front and back on the screw 42. The lower ends of the two supporting inclined rods 44 are respectively hinged to the tops of the corresponding two drive sliders 43, and the tops of the two supporting inclined rods 44 are both hinged to the bottom of the main bed board 2.

[0024] Reference Figures 1 to 3 The lifting base 41 is installed in the middle of the bed frame 1, serving as a connection and support. Rotating the screw 42 adjusts the two drive sliders 43 to move the two support rods 44 inward, supporting the main bed board 2 and causing the two side bed boards 3 to tilt outward; or rotating the screw 42 in the opposite direction adjusts the two drive sliders 43 to move the two support rods 44 inward, lowering the main bed board 2 and causing the two side bed boards 3 to tilt inward. During installation, the two drive sliders 43 are symmetrically and spaced apart to allow for sliding space.

[0025] Reference Figures 1 to 3 The top of the lifting base 41 is provided with a slide rail slider assembly 11, which includes a slide rail 111 and two movable sliders 112. The slide rail 111 is installed on the top of the lifting base 41 and located below the screw 42. The two movable sliders 112 are movably installed on the slide rail 111, and the tops of the two movable sliders 112 are respectively installed on the bottoms of two corresponding drive sliders 43.

[0026] Reference Figures 1 to 3The slide rail 111 is a linear slide rail 111, which can limit the deflection of the two movable sliders 112, keeping them in linear motion, and is used to support the two movable sliders 112. The two movable sliders 112 have ball bearings inside, which is existing technology. Combined with the linear slide rail 111, this facilitates movement and reduces friction. The two movable sliders 112 are installed at the bottom of the two drive sliders 43. When the screw 42 rotates, the two drive slide rails 111 are limited by the two movable sliders 112 and will not deflect, but will only move along the direction of the screw 42. At the same time, the two movable sliders 112 can support the two drive sliders 43, thereby transmitting the downward force of the two supporting inclined rods 44, which can prevent the screw 42 from bending and deforming under stress.

[0027] Reference Figure 1 and Figure 3 The screw 42 is equipped with an adjustment handle 12 at its front end. The design of the adjustment handle 12 makes it easier for medical staff to adjust the rotation of the screw 42, making it easier to adjust the main bed board 2 up and down.

[0028] Reference Figures 1 to 3 Usage: When transferring a patient from the hospital bed to the transport bed, adjust handle 12 to rotate screw 42 clockwise. At this time, both drive sliders 43 move outwards on screw 42, moving away from each other, and the two moving sliders 112 also move away from each other on slide rail 111. The relative angle between the two supporting diagonal rods 44 increases, the main bed board 2 lowers, and the two side bed boards 3 tilt inwards and downwards. This allows for quick transfer by simply moving the transport bed to the side of the hospital bed, pushing the patient to the edge of the side bed board 3, and then gently pushing the patient to slide onto the main bed board 2 via the tilted side bed board 3. When transferring a patient from the transport bed to the hospital bed, adjust handle 12 to rotate screw 42 counterclockwise. At this time, both drive sliders 43 move inwards on screw 42, moving closer to each other, and the two moving sliders 112 also move closer to each other on slide rail 111. At this point, the relative angle between the two supporting diagonal rods 44 decreases, the main bed board 2 rises, and the two side bed boards 3 tilt outward and downward. In this way, the transfer bed can be moved to the side of the hospital bed, the patient can be pushed to the edge of the main bed board 2, and then the patient can be gently pushed and slid onto the hospital bed through the tilted side bed boards 3. This allows for a quick transfer.

[0029] Example 2:

[0030] Reference Figure 3 and Figure 4This second embodiment is basically the same as the first embodiment, except that: the front end of the screw 42 is connected to a drive motor 13, which is mounted on the lifting base 41. A motor driver 14 and a motor adjustment panel 15 are mounted on the bed frame 1. The drive motor 13 can be a stepper motor with a reducer or a servo motor. By setting the motor driver 14, the forward and reverse rotation of the motor can be controlled, driving the screw 42 to rotate clockwise or counterclockwise, thereby adjusting the lifting height of the main bed board 2. Simultaneously, the motor adjustment panel 15 allows for manual operation with just a knob, eliminating the need for manual cranking, making operation more convenient and less strenuous.

[0031] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
