The present invention relates to the technical field of medical devices, and specifically relates to a novel medical electric moving trolley, which comprises a bed frame, a bottom plate, a lifting apparatus, a transfer plate, a transmission apparatus and a conveyor belt. Provided is a novel medical electric moving trolley, the transfer plate is provided on the bed frame and the conveyor belt is provided on the transfer plate, and the transmission apparatus can drive the transfer plate to slide on the bed frame and drive the conveyor belt to move, and so automatically transporting patients from a hospital bed onto the moving trolley or the automatic transfer from the moving trolley to another bed can be achieved, thus reducing manual handling workload, transfer operations are convenient, and secondary injuries on patients caused by substantial handling can be prevented. By providing the lifting apparatus between the bed frame and the bottom plate, the vertical height of the bed frame can be adjusted, and is suitable for transferring to hospital beds or operating tables of different heights. By providing a power wheel apparatus on the bottom plate, a large amount of manpower can be reduced to achieve the movement of the moving trolley, and usage is convenient.
A: Provided is an automatic patient transfer vehicle, which relates to the technical field of patient transportation and is used for cooperating with an automatic patient transfer robot to transfer a transported person. The vehicle comprises a vehicle body, a translational electric push rod, a support arm and a bracket, wherein the bracket is suitable for placing the automatic patient transfer robot, one end of the support arm is hinged to the vehicle body, the other end of the support arm is hinged to the bracket, one end of the translational electric push rod is connected to the vehicle body, the other end of the translational electric push rod is connected to the support arm, the translational electric push rod is adapted to control the movement of the bracket by controlling the rotation of the support arm, and the bracket is adapted to take and place the automatic patient transfer robot via movement. Further provided is an automatic patient transfer method. The automatic patient transfer vehicle and the automatic patient transfer method provided by the present invention can coordinate the automatic patient transfer robot to get on and off the automatic patient transfer vehicle; in addition the time of medical workers is saved on, the labor intensity of the medical workers and family members of a patient is reduced, and secondary injury to the transported person is avoided.
B: Provided is an electric lifting and moving machine (100) suitable for the technical field of medical instruments. The electric lifting and moving machine comprises: a bearing assembly, used for bearing a user and comprising a seat plate; a support assembly, comprising a chassis (20); an electric lifting assembly, comprising an electric motor driving assembly (90) and a lifting assembly, wherein the electric motor driving assembly (90) is in transmission connection with the lifting assembly, and the lifting assembly is arranged on the chassis (20); at least one connection rod (30), wherein one end thereof is connected to the lifting assembly, and the other end thereof is connected to the bearing assembly in such a way that the lifting assembly drives the bearing assembly to ascend or descend; at least one castor (21), arranged on a bottom side of the chassis (20); and at least one foot brake assembly, arranged, corresponding to the position of the castor (21), on the chassis (20), and when in a parked state, the foot brake assembly being in contact with the castor (21) so as to prevent the castor (21) from rotating. In the electric lifting and moving machine, automatic lifting of the moving machine is achieved, the structure is simple, the size is small, and the comfort of a user is improved.
C: A multifunctional full-automation care bed is formed of a chassis (1), a bed frame (2), a head board (9), a back board (7), a buttock board (6), a leg board, a foot board (3), double folded restraining sides, and a toilet fold mechanism. The back board and the buttock board are rotatable hinged boards, whose corresponding cushions are cylindrical cushions and move synchronously with the hinged boards. The back board and the buttock board are divided into three pieces longitudinally. The two pieces at the sides can fold upward, respectively. When one side board at one side is folded, the hinged boards and the rolling cushion move to the direction of the folded board, and a patient can turn over at 0 to 360 degrees. The toilet fold mechanism is installed below the leg board at the rear part of the bed frame. The middle piece of the leg board can rise driven by an electric push rod and support the legs of a patient and enable the buttocks to leave the cushion. A toilet (35) can automatically move below the buttocks of the patient as driven by the fold mechanism. The care bed is driven by a motor and eight electric push rods and is controlled by a microcontroller.
D: Disclosed in the present utility model is a novel nursing chair bed system, comprising a bed frame, the bed frame being provided with a backrest part, a foot rest part and a cushion part, the backrest part and the foot rest part being connected to the cushion part in an up-and-down rotating manner; a foot pad part is provided at one end of the foot rest part away from the cushion part, the foot pad part is rotatably connected to the foot rest part; said system further comprises a backrest push rod and a foot rest push rod, outer shells of the backrest push rod and the foot rest push rod are fixed to the bed frame; an actuating mechanism of the backrest push rod is fixedly connected to a back face of the backrest part; the outer shell of the foot rest push rod is fixed on the bed frame, and an actuating mechanism thereof is connected to a transmission mechanism; the transmission mechanism comprises a transmission frame and an L-shaped support frame, one end of the transmission frame being rotatably connected to the bed frame, and the other end being rotatably connected to one end of the L-shaped support frame; the other end of the L-shaped support frame is connected to one end of the foot pad part away from the foot rest part; and the actuating mechanism of the foot rest push rod is fixedly connected to the transmission frame. The present utility model can achieve a high degree of automation.
