Abstract

This invention relates to the field of medical device technology, and particularly to a device for the transfer and care of paralyzed patients. The device includes a frame, a lifting mechanism, and a transfer mattress. The lifting mechanism includes a U-shaped plate with symmetrical slots on both sides. A dual-axis extension motor is mounted on the U-shaped plate. The two output shafts of the dual-axis extension motor are connected to a positive threaded rod and a negative threaded rod. Adjusting rods are threaded onto and connected to both the positive and negative threaded rods. The two ends of the adjusting rods pass through the two slots and are equipped with hydraulic cylinders that can extend and retract vertically to raise or lower the transfer mattress. Insertion rods are located at the lower ends of the hydraulic cylinders. Insertion holes are located on both sides of the transfer mattress corresponding to the insertion rod positions. The dual-axis extension motor drives the positive and negative threaded rods to rotate forward, causing the two adjusting rods to move towards each other along the slots, allowing the insertion rods to insert into the insertion holes, thereby securing the transfer mattress. This invention prevents the patient from shaking or falling during transfer and completely eliminates the need for manual handling, making it convenient to use.
