ABSTRACT:
A flush device for an intravenous blood pressure monitoring system has a main body which includes a continuous flow channel and a fast flush channel. The continuous flow channel is integral with the main body and includes an inlet, a closed end which receives a laser drilled hole for fluid output, and an outlet. The continuous flow channel is separated from the fast flush channel by a median wall. An opening in the median wall is blocked by an elastomeric member disposed in an initial position in the fast flush channel. When the member is distended, the opening is unblocked, and fluid flow from the inlet to the outlet is through the fast flush channel. An alternative embodiment of the fast flush device has a tubular body with a capillary channel formed on an inner wall. An elastomeric member contained within the tubular body restricts flow to the capillary channel when the elastomeric member is in an initial position. When the elastomeric member is in a distended position fluid is allowed to overflow the capillary channel thus permitting either a fast flush flow between a source of medical fluid and the outlet on the fast flush device which is in fluid communication with the catheter.
