Description

Technical Field

[0001] This invention belongs to the field of medical transport bed technology, and relates to a transport bed that achieves seamless transportation based on manual-electric switching. Background Technology

[0002] In the medical system, patient transfer is a frequent operation. Commonly used methods involve ordinary wheeled or motor-driven transfer beds, requiring manual handling. This method is inefficient and may cause serious secondary injuries to critically ill patients during transport. Current technology typically combines a manual crank with a motor drive, using a chain to engage a crank and chain for seamless patient transfer. Control can be manual or electric. This technology supports seamless patient movement and bed raising / lowering, making it suitable for transfers between various operating rooms and departments.

[0003] Existing transfer beds that achieve seamless transfer using a combination of manual cranks and motor drives mainly include a bed lifting system, a bed sliding system, a fabric crossbar sliding system, and a control system. The bed lifting system controls the surface of the transfer bed to reach the same height as the patient's bed. The upper bed board in the bed sliding system is wrapped in a transfer fabric and is pushed outward by the system, allowing it to be moved seamlessly under the patient. Then, the bed sliding system is used to control the bed board to move inward, transferring the patient to the transfer bed. However, the disadvantages of existing medical transfer beds are: they generally require multiple people to operate and rely on manual labor during transport. If the patient is too heavy, this can cause serious secondary injuries during transport, especially when the patient is undergoing various medical examinations. Existing transfer beds are also limited in design, laborious to operate, and have severely limited transfer efficiency. Summary of the Invention

A lifting gear 20 is installed along the axis of the motor 14. The lifting gear 20 cooperates with the lifting rack 16. The lifting rack 16 is connected to the bed base plate 37 through the installed limiting post 18. A sliding guide rail is installed on the bed base plate 37. The sliding guide rail is used for the translational guidance of the lower bed plate 37. An upper bed plate 34 is installed on the lower bed plate 37. The upper bed plate 34 is wrapped around the perimeter by a transfer fabric 35. The transfer fabric 35 can be unfolded from the seam to form a rectangle. A fabric pulling crossbar 10 is installed at the seam of the transfer fabric 35. A crossbar positioning block is installed on both the left and right sides of the fabric pulling crossbar 10 (a crossbar fixing block 26 is installed on one side of the fabric pulling crossbar 10, and a crossbar fixing block 27 is installed on the other side of the fabric pulling crossbar 10). The crossbar positioning blocks are installed on the sliding guide rail. A connecting block 21 is installed on one side of the lower bed plate 36, and the connecting block 21 is connected to the transmission chain 22. The transmission chain 22 is installed on two transmission sprockets, and one transmission sprocket is aligned with the axis of the large gear 24. The large gear 24 and the small gear 25 are engaged. A detachable manual crank handle 22 is installed on one side of the small gear 25. The manual crank handle 22 is installed inside the gearbox 33. A coupling 23 is installed along the axis of the other transmission sprocket, and a motor 21 is installed on one side of the coupling 23. The motor 21 is installed on the outside of the gearbox 33. A remote control 13 is installed on the outside of the gearbox 33, and a gearbox cover plate 11 is installed on top of the gearbox 33.

[0021] In one aspect of this embodiment, when using the manual operation mode, medical staff use the remote control 13 to adjust to the manual mode, use the manual crank 7 to adjust the bed base 37 to the same height as the hospital bed, manually push the cloth crossbar 10 to the side of the bed base 37 closer to the patient to reset, adjust the switch on the motor 3 9 to the locking mode, and use the manual crank 2 12 to drive the transmission chain 22 to push out the lower bed board 36. As the bed board moves out, the transfer cloth 35 moves in the opposite direction, and the entire bed board enters under the patient without being felt.

[0022] In one aspect of this embodiment, the medical staff adjusts the switch on motor 39 to the idle mode, and uses the manual crank 212 to drive the transmission chain 22 to move the entire bed board inward. The transfer cloth 35 moves in the same direction as the bed board. At this time, the patient is slowly and imperceptibly moved into the transfer bed, and the medical staff pushes the transfer bed to the examination room to achieve imperceptible transfer.

[0023] The procedure for medical staff to transfer patients from the examination room back to their beds is the same as the procedure described above.
