Miniature intravenous infusion rate controller

机译:微型静脉输液速度控制器

摘要

An intravenous drip rate control device includes a trough in the rear face of the housing for receiving intravenous tubing. The intravenous tubing is placed within the trough between and in functional communication with a pair of resilient bands. A cam driven by a reversible DC motor moves a lever between a first and second position. In the first position, a blade extending upwardly from the lever is capable of contacting and engaging the tubing and restricting the tubing opening. A tubing door is pivotable about the rear face of the housing between an open and closed position. In the closed position, a plastic material layer extending downwardly from the tubing door contacts and engages the tubing to restrict the tube opening and also provides support for the tubing when the blade applies an upward force on the tubing. The resilient bands ensure minimal "plastic flow" of the tubing and constantly resist the tendency of the side walls of the tubing to extend out and thus the tubing to flatten out.
