Description

Medical transfer bed driven by ultrasonic motor

Technical Field

The invention relates to the technical field of medical instruments, in particular to a medical transfer bed driven by an ultrasonic motor.

Background

For a patient who cannot move autonomously, when nuclear magnetic resonance examination is performed, the patient needs to be transferred to a nuclear magnetic resonance room from an original sickbed, a transfer bed needs to be used, and the patient is transferred between the beds mostly in a lifting and holding mode. The whole process takes longer time, the moving speed is required to be fast in order to save the transfer time of a single patient, and secondary damage to the patient is inevitable in the moving process. In addition, the nuclear magnetic resonance special bed is required to have no magnetism, so the transfer bed with a common coil motor cannot directly enter a nuclear magnetic resonance chamber, the motor fails to be electrically driven when meeting a magnetic field, and the electric height adjustment and the side position adjustment of the transfer bed fail, so that the transfer bed is not convenient to use in the transfer process.

At present, the invention with publication number CN113749878A discloses a nuclear magnetic resonance patient transfer trolley, which comprises a trolley frame, a bedstead lifting mechanism, a brake mechanism and a panel moving mechanism, wherein the panel moving mechanism comprises: the chain wheel shaft, the two driving chain wheels, the two driven chain wheels, the chain positioning and mounting block, the reel frame and the panel; the upper parts of the front end and the rear end of the bedstead are fixedly provided with a slideway plate, a plurality of first sliding rollers are arranged in the slideway plate in parallel, panel supporting bars are fixed at the front end and the rear end of the panel, and a plurality of second sliding rollers are arranged in the panel supporting bars in parallel; the first sliding roller is contacted with the side surface of the panel supporting bar, and the second sliding roller is contacted with the upper side surface and the lower side surface of the slideway plate; the width of the panel is larger than that of the bed frame. The invention adopts a mode of manually operating the chain wheel shaft to drive the panel to move easily, and the transfer of the patient between the transfer trolley and the sickbed is completed. Although the height adjustment of the transfer bed is manually realized, the adjustment flexibility in use is still insufficient.

In order to solve the above problems, the present document provides a medical transfer bed driven by an ultrasonic motor.
