Medical infusion stand with function of cutting off entanglements

Abstract

The present invention provides a medical infusion stand with a function of cutting off entangled objects, comprising a top, a hook, a telescopic rod, a buckle device, a push plate, a bottom rod, a base and an anti-entanglement moving device. When medical staff infuse a patient, the buckle device is used to adjust the height of the telescopic rod, the push rod is pulled out, the telescopic rod is moved to a suitable position, the push rod is released, and under the action of a spring, the push rod is extended into a groove of the telescopic rod for fixation. The positioning boss of the telescopic rod and the positioning groove of the bottom rod cooperate to ensure that the push rod and the groove are not misaligned. During the movement of the infusion stand, the exposed blade tip on the anti-entanglement central axis can effectively prevent a part of the debris from being entangled. When the infusion stand is not moving smoothly, the push column on the side of the anti-entanglement central axis is pressed to move the movable blade outward along the radial direction of the central axis, which can effectively cut entangled debris such as hair and make the movable stand move smoothly again.
