[0004] In order to solve the technical problems mentioned in the above background technology part, some embodiments of the present application provide a medical transfer device, including a bed frame, electric retractable bed legs fixed on the bed frame, a transfer mechanism movably arranged on the bed frame, two baffles rotatably arranged on both sides of the bed frame, a support plate fixed on the electric retractable bed legs, and a control mechanism fixed on the support plate. The transfer mechanism includes a transfer plate movably arranged on the bed frame, a first clearance groove arranged on the transfer plate, an active roller rotatably arranged on the transfer plate, a driven roller rotatably arranged on the transfer plate, a conveyor belt wound around the active roller and the driven roller, a second clearance groove arranged on the bed frame, a first motor fixed on the transfer plate for driving the active roller, two fixed components fixed on the conveyor belt close to the driven roller, a driving component arranged in the bed frame for driving the transfer plate to move, and a walking aid component arranged on the transfer plate; the first motor is movably arranged in the second clearance groove.
[0005] Specifically, the stop rod is tightly matched with the bed frame.
[0006] Specifically, the fixing assembly includes a first rubber block fixed on the conveyor belt, and a second rubber block fixed on the conveyor belt and symmetrically arranged with the first rubber block; the first rubber block and the second rubber block are arranged in close contact.
[0007] Specifically, a first arc-shaped surface is provided on one side of the first rubber block; and the second rubber block has the same shape as the first rubber block.
[0008] Specifically, the driving assembly includes a third give way groove on the bed frame, a screw rod rotatably arranged in the third give way groove, a second motor fixedly arranged in the third give way groove and used to drive the screw rod to rotate, a roller rotatably arranged in the transfer plate, a moving block fixedly arranged at one end of the roller and cooperating with the screw rod, a smooth fixed rod fixedly arranged in the second give way groove, and a slider fixedly arranged at the other end of the roller and slidably arranged on the smooth fixed rod.
[0009] Specifically, the walking aid component includes a fourth give way groove provided on the transfer plate, a rotating rod rotatably provided in the fourth give way groove, a third motor fixed in the fourth give way groove and driving the rotating rod to rotate, two support rods respectively fixed at both ends of the rotating rod, and two rotating wheels respectively rotatably provided on the two support rods.
[0010] Specifically, the control mechanism includes a controller fixed on the support plate and a remote controller connected to the controller; the controller is respectively connected to the first motor, the second motor, and the third motor.
[0011] Specifically, a second arc-shaped surface is provided on a side of the transfer plate away from the second motor.
[0012] Specifically, the fourth clearance groove is arranged on a side close to the second arc-shaped surface.
[0013] The beneficial effects of the present invention are:
[0014] (1) When using the transfer device, first adjust the height of the electric telescopic bed legs so that the lower surface of the transfer board is aligned with the patient's bed, then turn the stop rod to make way for the transfer board to move, fix the bed sheet on the patient's bed to the two fixing components respectively, start the second motor to make the transfer board extend out of the bed frame and extend under the patient, and at the same time start the first motor to drive the active roller to rotate, and the two fixing components drive the bed sheet to move in the opposite direction of the transfer board. When the bed sheet is pulled, one side of the patient's body is slightly lifted to facilitate the transfer board to extend under the patient. At the same time, the conveyor belt can also drive the patient to move. The patient is transferred to the transfer board more quickly. After the patient is completely moved to the transfer board, the first motor is turned off and the second motor is reversed, so that the transfer board brings the patient back to the bed frame, completing the transfer of the patient from the bed to the transfer device. The medical transfer device with the above structure can automatically transfer the patient to the transfer device without the need for medical staff to move the patient, thereby reducing the risk of secondary injury. Pulling the bed sheet can slightly lift one side of the patient's body, making it easier for the transfer board to extend under the patient, preventing the transfer board from squeezing the patient's skin during the process of extending under the patient, thereby improving the patient's comfort.
[0015] (2) A fourth clearance groove is provided on the transfer board. The two support rods are initially arranged horizontally with the lower surface of the transfer board. When the patient is completely transferred to the transfer board, the third motor is started to drive the rotating rod to rotate so that the two support rods are perpendicular to the lower surface of the transfer board. The two rotating wheels are in contact with the patient's bed, and the side of the transfer board away from the second motor is slightly lifted. The third motor is turned off, and the second motor is reversed to drive the transfer board and the patient back to the bed frame. In the process, due to the setting of the rotating wheels, the contact area between the lower surface of the transfer board and the patient's bed is reduced, the friction force is reduced, and the transfer board is easier to move from the bed. In addition, the side of the transfer board away from the second motor is lifted, so that the transfer board is slightly tilted, which can prevent the patient from slipping off the transfer board and causing secondary injury, so that the patient can be transferred to the medical transfer device more safely.
