Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a human body transport device and a transport method thereof suitable for hospitals. Background Art

[0002] Currently, domestic medical institutions have a large number of operating rooms, and the number of surgeries is growing rapidly. However, during surgery, patient transfers are primarily performed by family members, assisted by medical staff, who manually transfer patients from the operating table to the hospital bed. This manual transfer method is labor-intensive and can easily cause secondary injuries to patients. Summary of the Invention

[0003] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a human body transfer device suitable for hospitals, which can overcome the problems of high labor intensity of traditional manual transfer and difficult synchronous control of the motor of the existing synchronous belt transfer device and complex structure. It drives the lifting and lowering of the manipulator workbench and the parallel movement of the manipulator claw through the motor, and cooperates with the movable profile frame to complete the transfer of patients between the operating table, transfer bed and hospital bed.

[0004] Another object of the present invention is to provide a transport method for the above-mentioned human body transport device suitable for hospitals.

[0005] The technical solution of the present invention is: a human body transfer device suitable for hospitals, comprising a profile frame, a turbine screw lifting mechanism, a manipulator workbench, a screw slide module and a transfer mechanism;

[0006] The worm screw lifting mechanism is connected to the top of the profile frame, and the worm screw lifting mechanism is connected to the manipulator workbench. The manipulator workbench is located below the worm screw lifting mechanism, and the worm screw lifting mechanism is used to lift or lower the manipulator workbench.

[0007] The two screw slide modules are respectively connected to the manipulator workbench and symmetrically distributed on both sides of the manipulator workbench. The screw slide module is connected to the transfer mechanism and is used to drive the transfer mechanism to move horizontally.

The grabber hooks on the two transfer mechanisms are closed or separated in the horizontal direction.

[0009] Furthermore, the profile frame includes columns, short connecting beams, long connecting beams and support beams. Two adjacent columns in the length direction are connected by the long connecting beam, and two adjacent columns in the width direction are connected by the short connecting beam. The support beam is connected to the top surface of the column, and the turbine screw lifting mechanism is connected to the support beam.

[0010] Furthermore, casters with brakes are provided at the bottom of the column.

[0012] Furthermore, the worm screw lifting mechanism further includes a guide mechanism, which includes a guide rod and a connecting bearing, one end of the guide rod being connected to the manipulator workbench, and the other end being connected to the elevator mounting plate via the connecting bearing. The provision of the guide rod ensures that the manipulator workbench can be lifted and lowered smoothly.

[0013] Furthermore, the guide mechanism includes a stopper connected to the end of the guide rod away from the manipulator workbench. The stopper is located above the elevator mounting plate and is used to prevent the end of the guide rod away from the manipulator workbench from separating from the elevator mounting plate. The stopper prevents the entire manipulator workbench from falling in the event of a lift mechanism failure, thereby ensuring patient safety.

[0015] Furthermore, the grab hook includes a vertical section and a horizontal section, the vertical section is vertically connected to the horizontal section, and the vertical section is connected to the grab hook connecting plate.

[0016] Furthermore, the multiple grab hooks are arranged at intervals, and the distance between two adjacent grab hooks is the width of a grab hook, so that the multiple grab hooks of the two transfer mechanisms can be closed tightly, ensuring that the forces of the two transfer mechanisms are balanced and enhancing the stability of the transfer process.

[0017] Another technical solution of the present invention is: the above-mentioned transfer method of the human body transfer device suitable for hospitals is to first move the profile frame to the top of the bed and fix it, and then the medical staff tilts the patient's body from one side, and the screw slide module on that side controls the transfer mechanism on that side to move parallel to the bottom of the patient. After the medical staff lets go, the patient naturally lies flat on the multiple hooks of the transfer mechanism on one side, and the turbine screw lift mechanism drives the manipulator workbench to rise so that the patient is suspended in the air, and then the screw slide module on the other side controls the transfer mechanism on the other side to move parallel to the two transfer mechanisms closing, and then move the profile frame to the target location, and perform the above operations in reverse, place the patient on the bed, and complete the transfer of the patient.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The human body transfer device suitable for hospitals of the present invention uses a mechanical method to complete the patient's transfer. It has a simple and reliable structure and can replace manual labor to complete the patient's transfer without changing the patient's posture, thereby enhancing the patient's comfort and alleviating the patient's pain, and reducing the labor intensity of medical staff while ensuring the safety and comfort of the patient.

The elevator mounting plate is connected to the support beam, and the worm screw elevator is connected to the middle of the elevator mounting plate. The manipulator workbench is located below the elevator mounting plate, and the screw of the worm screw elevator is connected to the manipulator workbench through a flange. The guide mechanism includes a guide rod 23, a connecting bearing, and a stopper. One end of the guide rod is connected to the manipulator workbench, and the other end is connected to the elevator mounting plate through a connecting bearing. By providing the guide rod, the manipulator workbench is ensured to be lifted and lowered smoothly. The stopper is connected to the end of the guide rod away from the manipulator workbench. The stopper is located above the elevator mounting plate and is used to prevent the end of the guide rod away from the manipulator workbench from detaching from the elevator mounting plate. By providing the stopper, the entire manipulator workbench is prevented from falling when the lifting mechanism fails, thereby ensuring the safety of the patient. In this embodiment, the stopper is a pin inserted into the guide rod.

[0030] like Figure 2 and Figure 3 As shown, the screw slide module includes a base 41, a threaded screw 42, a screw block 43, a guide rail 44, a guide rail block 45, a sliding plate 46, and a drive motor 47.
