Technical Field

[0001] This utility model relates to the field of medical transfer vehicle structure technology, and in particular to a medical transfer vehicle. Background Technology

[0002] A medical transfer vehicle is a vehicle specifically designed for transporting patients within a hospital, moving patients from one location to another, such as from the emergency room to a ward.

[0003] Traditional transfer cart guardrails consist of a frame end and multiple fence ends. These guardrails offer only basic protection. However, during the transfer of a patient from the medical transfer cart to the bed, a gap often exists because the cart and bed rarely fit perfectly together. The patient's hands and feet may get caught in this gap, causing discomfort. Therefore, there is room for improvement. Thus, a new type of medical transfer cart is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

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

[0006] A medical transfer cart includes a transfer bed frame. A panel assembly is provided at the top of the transfer bed frame. The panel assembly includes a splicing plate. A reclining board is movably installed on the left side of the splicing plate. Guardrail assemblies are provided on both sides of the top of the transfer bed frame. Each guardrail assembly includes end seats fixed to opposite sides of the end of the transfer bed frame's support rod. A shaft connects the two end seats, and a movable plate seat is movably installed on the surface of the shaft. A guardrail plate is bolted to the top of the movable plate seat, and snap-fit ​​fittings are movably installed on the surface of the end seats.

[0007] Preferably, the bottom end of the splicing plate is connected to a support, and the end of the support is movably connected to a telescopic rod. The piston rod end of the telescopic rod is movably connected to the inclined plate. By extending and retracting the piston rod end of the telescopic rod, the inclined plate is pushed, controlling the rotation of the inclined plate on the left side of the splicing plate, thereby adjusting the tilt angle of the inclined plate.

[0008] Preferably, the inner wall of the guardrail has a slot, and a snap-fit ​​shaft is inserted into the slot. The end of the snap-fit ​​shaft is connected to a rubber pad, and the rubber pad is fitted to the inner wall of the guardrail through a groove. The snap-fit ​​shaft is embedded in the slot of the guardrail, so that the rubber pad can fit against the inner wall of the guardrail. When the guardrail is placed flat, the guardrail can provide a platform for the patient to move.

[0009] Preferably, the snap-fit ​​accessory includes a first snap-fit ​​block, which is movably mounted on the surface of the end seat via a guide groove. A rectangular plate end is provided on one side of the movable plate seat, and a groove adapted to the first snap-fit ​​block is provided on the side of the rectangular plate end. After the first snap-fit ​​block moves in the guide groove of the end seat, it is inserted into the groove of the rectangular plate end of the movable plate seat, thereby locking the guardrail and ensuring the stability of the guardrail when it is placed upright.

[0010] Preferably, the bottom end of the end seat is connected to a limiting plate, and the maximum rotation angle of the movable plate seat is 90°. The limiting plate can provide initial support for the rotation of the movable plate seat, so that the guardrail can be suspended in a suspended state during rotation.

[0011] Preferably, the first card block is connected to a connecting frame on the front, and the connecting frame is connected to a second card block at its end. The second card block is embedded in the front of the end seat through a guide groove. The top of the first card block is connected to a handle.

[0012] Preferably, the vertical cross-sections of the first and second blocks are both I-shaped. The ball is movably mounted on the bottom of the second block and the ball through a ball groove. A return spring is connected to the side of the second block, and the end of the return spring is fixed to the inner wall of the end seat guide groove. When the first and second blocks move, the ball can be driven to roll due to friction, ensuring the smoothness of the movement of the first and second blocks.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. By setting up a guardrail assembly, the patient can be transferred safely. Compared with the traditional structure, this device uses a movable plate base to rotate and move the guardrail plate to the side of the hospital bed, thereby covering the gap between the transfer bed frame and the hospital bed. By turning the handle, the first locking block can be moved. The first locking block moves in the guide groove on the end seat surface, so that the first locking block can be locked in the locking groove on the side of the movable plate base. This ensures that the guardrail plate can be rotated and stably placed horizontally on the hospital bed surface, which facilitates the transfer of patients when the transfer bed frame and the hospital bed are side by side. It also prevents the patient's hands and feet from getting stuck in the gap during the transfer, causing discomfort or secondary injury to the patient.

[0015] 2. By setting up the plate assembly, the tilt adjustment of the reclining board can be realized. This device can push the reclining board by extending and retracting the piston rod end of the telescopic rod, so that the right side of the reclining board can rotate around the left axis end of the splicing plate as the center, which facilitates the tilt adjustment of the reclining board to meet the needs of patients. At the same time, the inner wall of the reclining board has a slot for inserting a locking shaft, and a rubber pad is laid on the inner wall of the guardrail. When the guardrail is rotated and placed flat, the rubber pad can improve the comfort of the patient when moving and reduce the chance of secondary injury caused by movement.
