Return the transfer device to complete the transfer work.

A hospital patient transfer device of the present invention is used to transfer a patient, and the specific transfer method is as follows:

Move the transfer bed to the side of the patient's position by the escort, confirm that the transfer mattress 5 is arranged directly under the patient's body, and overcome the compression spring force to move the guardrail handle 14 out of the pin hole foot seat 12, so that the guardrail handle 14 is lowered to the transfer position. On the lower side of the bed board 2a, lower the telescopic support column 8 to prevent the movement of the transfer device, and complete the preparatory work before the transfer.

The escort operates the controller, and the single-lift hydraulic cylinder 21 works to control the sliding shoe 18 at the end of the scissor rod 19 to slide in the embedded slideway of the upper platform 17 and the scissor base 22, and then adjust the height of the upper platform 17, thereby controlling the shearing The height of the fork lift platform 2b is such that the height of the transfer bed 2a connected to the scissor lift platform 2b is the same as the height of the patient, so as to prevent the patient from being uncomfortable during the transfer.

Control the vertical electric push rod 29 to extend, so that the vertical telescopic arm 27 extends from the vertical telescopic boom 28, and control the horizontal electric push rod 26 to extend, so that the horizontal telescopic arm 24 extends from the horizontal telescopic boom 25 , because the vertical telescopic boom 28 of the manipulator 3 is connected with the manipulator base 30 by bolts, the manipulator base 30 is fixed with the bed slide block 16 on the central bed slide rail 15 of the transfer bed 2a, and the end is connected with the card holder 23 and the The U-shaped connecting plate 31 in the center of the pulling mechanism 4 is fixed.
