Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a transfer bed. Background Technology

[0002] A patient transport bed is a tool used for transferring patients between beds. It can move patients from the operating table to the ward, or from an ambulance to a dedicated medical bed. Because of its multi-position lifting and lowering capabilities, flexible movement, and ease of operation, the patient transport bed has changed the traditional methods of patient transfer, making the process more convenient and faster. It solves the difficulties of transferring patients from the operating table to the ward after surgery, reduces the difficulties and pain for doctors and nurses, and minimizes the pain and hardship caused by traditional manual patient transfers. Therefore, it is widely used in hospitals and is an essential piece of medical equipment.

[0003] However, in actual use, existing transport beds still require multiple people to lift and carry patients when transferring them out of the transport bed, which can easily cause pain and secondary injury to the patient, especially for heavy patients, making the transfer operation more difficult; therefore, a new type of transport bed is proposed as a further improvement. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a transfer bed to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a transfer bed, comprising a bed body, a C-shaped fixed frame fixedly installed on the top of the bed body, and strip-shaped movable frames slidably connected to the inner walls on both sides of the fixed frame, the two movable frames being fixedly connected by a connecting rod, and a pushing mechanism being provided between the connecting rod and the fixed frame;

[0006] A transport plate is provided between the two mobile frames;

[0007] The transport platform includes a first support plate and a second support plate that are detachable and distributed on the left and right sides. A locking mechanism for preventing slippage is provided between the first support plate and the second support plate and the movable frame.

[0008] Furthermore, the fixed frame has strip-shaped limiting grooves on its inner walls on both sides, and the movable frame slides inside the limiting grooves.

[0009] Furthermore, the pushing mechanism includes a pushing screw and a moving block. The middle of the fixed frame is provided with a pushing groove parallel to the limiting slide groove and the moving frame. The axial direction of the pushing screw is parallel to the pushing groove. The two ends of the pushing screw are rotatably connected to the inner walls of the two ends of the pushing groove, respectively. The moving block is threadedly connected to the pushing screw. The top of the moving block is fixedly connected to the bottom of the connecting rod. One end of the pushing screw is fixedly connected to a rotating shaft, which passes through the pushing groove. The other end of the rotating shaft is fixedly connected to a control panel.

[0010] Furthermore, the inner walls of the two movable frames that are close to each other are fixedly connected to both sides of the C-shaped support slide rail. The transport plate is placed on the support slide rail and slides on the upper surface of the support slide rail. The connecting rod is fixedly connected to the side of the support slide rail.

[0011] Furthermore, the first support plate has an inclined surface at one end near the second support plate, and the second support plate has a matching groove near the inclined surface. After the inclined surface and the groove are fitted together, the upper surface of the first support plate and the upper surface of the second support plate are on the same horizontal plane.

[0012] Furthermore, the locking mechanism includes: a threaded hole and a plurality of locking bolts with knobs;

[0013] The threaded hole includes: a first threaded hole and a second threaded hole;

[0014] The first threaded hole is formed on the first support plate and the support slide rail, and the locking bolt is inserted into the first support plate and the support slide rail and threadedly connected to the first threaded hole.

[0015] The second threaded hole is formed on the second support plate and the support slide rail, and the locking bolt is inserted into the second support plate and the support slide rail and threadedly connected to the second threaded hole.

[0016] Furthermore, the threaded hole also includes: a third threaded hole;

[0017] The third threaded hole is located at the inclined surface and the groove. After the inclined surface and the groove are in contact, the locking bolt passes through the first support plate, the second support plate and the support slide rail and is threadedly connected to the third threaded hole.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] Compared to existing technologies, this invention, by incorporating a pushing mechanism, allows the mobile frame to be moved manually via a mechanical system. This enables the transport tray to move laterally above the patient's bed, where the first and second support plates then separate, allowing the patient to slide into the bed. This operation can be performed independently by a medical staff member, eliminating the need for manual lifting and preventing secondary injury to the patient. The transport tray can be quickly disassembled, significantly improving the convenience of transporting heavier patients. Therefore, this invention saves time and effort, enabling smooth patient transfer. The locking mechanism ensures that the movement of the mobile frame and the transport tray are synchronized, preventing uncontrolled separation of the tray. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0040] As attached Figure 1-8 The transfer bed shown includes a bed body 1, and a C-shaped fixing frame 2 is fixedly installed on the top of the bed body 1. The C-shaped fixing frame 2 can protect the patient in three directions on the horizontal plane, while the remaining direction is the direction of movement, which is protected by the transport plate 6.

[0041] The inner walls on both sides of the fixed frame 2 are slidably connected with strip-shaped movable frames 3. The two movable frames 3 are fixedly connected by a connecting rod 4. A pushing mechanism 5 is provided between the connecting rod 4 and the fixed frame 2.

[0042] A transport platform 6 is provided between the two mobile frames 3;

[0043] The pallet 6 includes: a first support plate 61 and a second support plate 62 that are detachable and distributed on the left and right sides.

[0044] The first support plate 61 and the second support plate 62 are both L-shaped to protect the patient. The two ends that are far apart from each other are also provided with gripping grooves so that medical staff can pull the first support plate 61 and the second support plate 62 apart, and then the patient can slide into the hospital bed from between the first support plate 61 and the second support plate 62.

[0045] A locking mechanism 7 for preventing slippage is provided between the first support plate 61, the second support plate 62 and the movable frame 3.

[0046] The pushing mechanism 5 can be manually driven by the mechanical mechanism to move the mobile frame 3, thereby moving the transport plate 6 laterally above the bed of the patient to be placed. Then the first support plate 61 and the second support plate 62 separate so that the patient can slide into the bed. This operation can be performed independently by a medical staff member, thus saving time and effort. The patient does not need to be lifted or carried, thus avoiding secondary injury to the patient. Especially for heavy patients, the convenience of this utility model during transportation is clearly demonstrated.

[0047] Among them, the locking mechanism 7 can ensure that the movement of the moving frame 3 drives the transport plate 6 to move, and prevent the transport plate 6 from separating uncontrollably;

[0048] In a preferred embodiment, as shown in the appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, the inner walls of the fixed frame 2 on both sides are provided with strip-shaped limiting grooves 21, and the movable frame 3 slides inside the limiting grooves 21.

[0049] The limiting groove 21 can limit the movement of the moving frame 3, so as to prevent the moving frame 3 from being misaligned or deviated when sliding.

[0050] In a preferred embodiment, as shown in the appendix Figure 3 and attached Figure 4 As shown, the pushing mechanism 5 includes: a pushing screw 51 and a moving block 52. The middle part of the fixed frame 2 is provided with a pushing groove 22 that is parallel to the limiting slide groove 21 and the moving frame 3. The axial direction of the pushing screw 51 is parallel to the pushing groove 22. The two ends of the pushing screw 51 are rotatably connected to the inner walls of the two ends of the pushing groove 22 respectively. The moving block 52 is threadedly connected to the pushing screw 51. The top of the moving block 52 is fixedly connected to the bottom of the connecting rod 4. One end of the pushing screw 51 is fixedly connected to a rotating shaft 53. The rotating shaft 53 passes through the pushing groove 22. The other end of the rotating shaft 53 is fixedly connected to a control panel 54.

[0051] Among them, the independent operation of the control panel 54 by medical staff can drive the rotating shaft 53 to rotate, and the rotating shaft 53 drives the push screw 51 to rotate. Then the moving block 52 moves along the push screw 51, and the moving block 52 pushes the moving frame 3 to move through the connecting rod 4.

[0052] In a preferred embodiment, as shown in the appendix Figure 2 Appendix Figure 4 Appendix Figure 5 and attached Figure 6 As shown, the inner walls of the two movable frames 3 are close to each other and are fixedly connected to both sides of the C-shaped support slide rail 8. The transport plate 6 is placed on the support slide rail 8 and slides on the upper surface of the support slide rail 8. The connecting rod 4 is fixedly connected to the side of the support slide rail 8.

[0053] The mobile frame 3 uses the support slide rail 8 to limit the transport plate 6, allowing it to slide in a specified direction.

[0054] In a preferred embodiment, as shown in the appendix Figure 6 Appendix Figure 7 and attached Figure 8As shown, the first support plate 61 has an inclined surface 611 at one end near the second support plate 62, and the second support plate 62 has a groove 621 that fits into the inclined surface 611. After the inclined surface 611 and the groove 621 fit together, the upper surface of the first support plate 61 and the upper surface of the second support plate 62 are on the same horizontal plane.

[0055] When the first support plate 61 and the second support plate 62 are separated, the second support plate 62 is pulled first so that the patient will slide down the inclined surface 611 of the first support plate 61 into the bed below, instead of falling directly onto the bed below, thus ensuring a comfortable transfer.

[0056] In a preferred embodiment, as shown in the appendix Figure 7 As shown, the locking mechanism 7 includes: a threaded hole 71 and a plurality of locking bolts 72 with knobs;

[0057] The threaded hole 71 includes: a first threaded hole 711 and a second threaded hole 712;

[0058] The first threaded hole 711 is formed on the first support plate 61 and the support slide rail 8. A locking bolt 72 is inserted into the first support plate 61 and the support slide rail 8 and is threadedly connected to the first threaded hole 711 so that the locking bolt 72 fixes the first support plate 61 on the support slide rail 8; thereby preventing slippage.

[0059] The second threaded hole 712 is formed on the second support plate 62 and the support slide rail 8. A locking bolt 72 is inserted into the second support plate 62 and the support slide rail 8 and is threadedly connected to the second threaded hole 712 so that the locking bolt 72 fixes the second support plate 62 on the support slide rail 8, thereby preventing slippage.

[0060] In a preferred embodiment, as shown in the appendix Figure 8 As shown, the threaded hole 71 also includes: a third threaded hole 713;

[0061] The third threaded hole 713 is located at the inclined surface 611 and the groove 621. After the inclined surface 611 and the groove 621 are in contact, a locking bolt 72 passes through the first support plate 61, the second support plate 62 and the support slide rail 8 and is threadedly connected to the third threaded hole 713. This allows the locking bolt 72 to fix the first support plate 61 and the second support plate 62 on the support slide rail 8, thereby preventing slippage.

[0062] The working principle of this utility model is as follows: When the patient is lying on the transport board 6, the bed 1 is first placed next to the bed of the patient to be placed. Then, the medical staff independently operates the control panel 54 to drive the moving frame 3 to move, thereby moving the transport board 6 laterally above the bed of the patient to be placed. Then, the locking bolt 72 is turned to release the fixed connection between the first support plate 61, the second support plate 62 and the support slide rail 8. Then, the second support plate 62 is pulled to make the patient slide down the inclined surface 611 of the first support plate 61. As the first support plate 61 is pulled open, the patient slides completely into the bed below, completing the transfer operation. Finally, the control panel 54 is controlled to reset the moving frame 3, and the transport board 6 is placed back on the support slide rail 8 on the moving frame 3.
