Description

Technical Field

[0001] The invention relates to the technical field of speed-controllable electric multifunctional flat carts, and in particular to a speed-controllable electric multifunctional flat cart. Background Art

[0002] Patient transfer is very common in clinical medical and nursing work, and the use of flatbed carts during transfer is also very frequent. The problems often encountered in the use of flatbed carts are as follows: flatbed carts with good performance are relatively heavy overall, which puts greater pressure on staff when encountering slopes and turns. Flatbed carts are long, and the ward door is a single door. Transfers need to be performed on the patient's head side, which often results in rear-end collisions, such as hitting the door or the patient's feet, which can easily cause damage to the door edge, damage to fire hydrants, patient injuries, and reduced satisfaction of patients and their families.

[0003] Patients who use flatbed carts are generally in critical conditions, and they often need to be lifted when transferring beds. Such operations are a test for both staff and patients: medical and technical staff are prone to twisting their waists, bumping their arms, and becoming exhausted when transferring beds, while patients are prone to falling down in the process, and there have been complaints of "I was thrown onto the bed". Flatbed cart transfers or transfers are often operated by at least two people. Sometimes restrictions on accompanying people or visiting further highlight the difficulties encountered in flatbed cart transfers. Current lathes are not designed with fully universal wheels, and the change in sense of direction can be clearly felt to be not flexible enough during turning. Moreover, the overall body of the lathe is heavy, which places high demands on the physical fitness of the transfer personnel. When turning, the tail is prone to slow changes and collisions.

[0004] Therefore, the present invention proposes a controllable speed electric multifunctional flat car to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a speed-controllable electric multifunctional flat car to solve the problems raised in the above-mentioned background technology.
