Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a device for rapid transfer of emergency critically ill patients. Background Art

[0002] A transfer bed is a special medical bed used to transfer patients between beds, from the operating table to the ward. The medical bed is often equipped with side panels to prevent patients from falling. The use of the transfer vehicle solves the difficulty of transferring patients from the operating table to the ward after surgery, and reduces the pain and difficulty caused to patients by traditional hand-lifting. It is now used in major hospitals and is an essential medical equipment for hospitals. Critically ill patients include those in a coma, receiving sedation treatment, and those who cannot move their bodies independently.

[0003] The existing emergency critically ill patient transfer bed has defects. There is no effective auxiliary fixation for patients with leg injuries, which cannot improve the treatment and rehabilitation experience of patients with leg injuries in different medical scenarios. In addition, the side panels cannot be hidden, which can easily cause secondary injuries to patients with severe leg injuries. Therefore, we propose a rapid transfer device for emergency critically ill patients. Summary of the invention

In special circumstances, the second guide rail 37, the third guide rail 39 and the folding bed board 391 are extended to the outside of the transfer device 1 to carry another seriously injured patient, which has good applicability.

[0054] Working principle:

[0055] First, move the transfer device 1 to the position where it is needed. When a patient with a leg injury needs to be transferred, gently place the patient on the transfer device 1. At this time, the U-shaped side panel 45 is in a hidden state. Start the bidirectional motor 32 for bidirectional movement, driving the adjusting rod 44 to lift the U-shaped side panel 45 and adjust it to a suitable state. At this time, the U-shaped side panel 45 is lifted to prevent damage to the patient with a leg injury during placement. Then start the third motor in the transmission structure 6 to drive the first driving wheel 61, the first driven wheel 63 and the second driven wheel 64 to drive clockwise. When the inner gear ring 72 rotates, the gear 74 meshing therewith rotates. The rotation of the gear 74 drives the rack 73 to extend and retract on the card frame 71, and at the same time drives the four auxiliary frames 76 to temporarily assist in fixing the patient's legs. At the same time, the bidirectional motor 32 drives the screw to drive, and the second guide rail 37 slides to the right along the first slide rail 33, and the third guide rail 39 follows The second guide rail 37, the third guide rail 39 and the folding bed board 391 are extended to the outside of the transfer device 1 along with the transmission belt 36, and another seriously injured patient can be carried. It has good applicability. After use, the third motor in the transmission structure 6 is first started to drive the first driving wheel 61, the first driven wheel 63 and the second driven wheel 64 to drive counterclockwise. When the inner ring gear 72 rotates counterclockwise, the gear 74 meshing therewith rotates accordingly. The rotation of the gear 74 drives the rack 73 to extend on the card frame 71, and at the same time drives the four auxiliary frames 76 to relax the patient's legs, and the bidirectional motor 32 is started to drive the adjusting rod 44 to hide the U-shaped side panel 45. Finally, the bidirectional motor 32 drives the screw to drive, and the second guide rail 37 slides along the first slide rail 33, and the third guide rail 39 follows the transmission belt 36 to realize the three-folding of the folding bed board 391. At this point, the entire workflow is completed.
