Summary of the invention

[0010] The present invention is intended to provide a medical transfer bed to solve the problem in the prior art that when transferring a patient, the patient needs to be directly lifted and transferred back and forth between the transfer bed and the examination bed, which may easily cause secondary injuries to the patient.

[0011] A medical transfer bed in the present scheme includes a bed board, a supporting leg is arranged under the bed board, baffles are arranged on two opposite sides of the bed board, and the two baffles are both located in the width direction of the bed board; a support plate that slides horizontally in the width direction of the bed board is connected between the two baffles, and a transfer plate that slides horizontally in the width direction of the bed board is arranged directly above the support plate, and the transfer plate is located between the two baffles, and a gear is arranged between the transfer plate and the support plate, and the gear is fixedly connected with a rotating shaft, and one end of the rotating shaft extends to the outside of the baffle; the support plate and the transfer plate are evenly distributed with teeth meshing with the gears; the multiple rows of teeth on the transfer plate are distributed along the width direction of the transfer plate; the multiple rows of teeth on the support plate are distributed along the width direction of the support plate.

[0012] The working principle and beneficial effects of this solution are as follows: when transferring a patient from a transfer bed to an examination bed, place the mattress on the transfer board, and make one side of the transfer bed in the length direction contact with the examination bed, so that the bottom surface of the transfer board is flush with the upper surface of the examination bed; then rotate the shaft clockwise, and the shaft drives the gear to rotate clockwise. During the rotation of the gear, the transfer board is driven to move to one side of the examination bed, and the transfer board is transferred to the examination bed. At this time, the patient is also transported to the examination bed; during this period, the support plate moves to the side away from the examination bed.

[0013] When the patient needs to be transferred from the examination bed to the transfer bed, the shaft is rotated counterclockwise, which drives the gear to rotate. During the rotation of the gear, the transfer plate moves toward the transfer bed; and the support plate moves to the side close to the examination bed. The transfer bed in this solution can realize the transfer of patients without the need to lift the patient manually, thereby avoiding secondary injuries to the patient during the lifting process.

[0014] Furthermore, elastic pads are provided at both ends of the support plate, the upper end surface of the elastic pads is in contact with the bottom of the transfer plate, and grooves are provided on the elastic pads for the teeth on the transfer plate to pass through. By providing the elastic pads, the elastic pads can help to support the transfer bed and reduce the inclination of the transfer plate. At the same time, in the process of the transfer plate driven by the gear to move, the elastic pads can help to reduce the shaking between the two, thereby improving the comfort of the patient. By providing the grooves, in the process of the transfer plate moving, the teeth pass through the grooves, so that the transfer plate and the elastic pads are always in gentle contact, avoiding the situation where the teeth are stuck on the elastic pads, which helps to move the transfer plate and the stability of the moving process.

[0015] Furthermore, the plurality of teeth on the support plate are located between the two elastic pads, and there is a gap between the teeth at both ends and the elastic pad. There is a gap between the elastic pad and the teeth, and when the gear drives the support plate to move, after moving a distance in the same direction, the transfer plate can be controlled to continue to move while the support plate is in a stopped state, so that it can move quickly when moving in the direction, avoiding reinstallation. At the same time, since the outward movement distance of the support plate is reduced, it is helpful to reduce the overall occupied area of ​​the medical transfer bed.

[0016] Furthermore, the upper surface of the bed board is rotatably connected with a plurality of rollers, the rollers are in contact with the lower surface of the support board, and the rotation direction of the rollers is consistent with the moving direction of the support board. By providing the rollers, it is helpful to reduce the resistance of the support board during the movement.

[0017] Furthermore, the upper surface of the transfer board is provided with a placement groove for placing a mattress. By providing the placement groove, the mattress can be effectively fixed, so that the stability of the mattress is better during the movement of the transfer board, making the patient's transfer process more stable.
