Abstract
The invention provides an infusion device flow fine-adjustment device. The infusion device flow fine-adjustment device comprises an adjusting wheel, wheel boxes and a middle shaft. One side face of the adjusting wheel is provided with a flow adjusting trough, wherein the flow adjusting trough is of an arc shape and the depth of the flow adjusting trough is gradually reduced. The other side face of the adjusting wheel is provided with a flow channel trough, wherein the flow channel trough is circular and the depth of the flow channel trough is constant. The circle center of the flow channel trough and the circle center of the flow adjusting trough are located on the axis of a middle shaft. A through hole connected with the flow channel trough is formed in the deepest position of the flow adjusting trough. The wheel boxes are arranged on the two sides of the adjusting wheel. The adjusting wheel is connected with the wheel boxes for positioning through the middle shaft. The wheel boxes on the two sides are respectively provided with a guide pipe. The ends of the two guide pipes are communicated with the flow adjusting trough and the flow channel trough respectively. The infusion device flow fine-adjustment device has the advantages of being simple in structure, low in manufacturing cost and safe and reliable in use and enabling flow to be adjusted by one hand.
