Patent ID: 7976515

Claim:
A flow regulator for IV tubing, comprising: a housing having an IV tube running through it; a roller-wheel carried within said housing on a first side of said IV tube and adjustable therein to impart a controlled bias against said IV tube, thereby selectively adjusting fluid flow through said IV tubing; an elongate pressure plate pivotally mounted in said housing on a second side of said IV tubing opposed to said first side, said pressure plate pivotable between a fixed first position in which it bears on said IV tube to provide a backing against the bias of said roller-wheel, and a second position in which said IV tube is released from the bias imparted by said roller-wheel; and a manual actuator mounted to said housing and engaged to said pressure plate, said manual actuator comprising a depressible member movable from a normally-closed position to an open position, said depressible member having a protruding release member disposed to engaged said pressure plate , and a sustained return mechanism engaged to said depressible member for gradually returning said depressible member to said normally-closed position, and said protruding release member engaging said pressure plate to maintain it in said fixed first position when said depressible member is in said normally-closed position, and releasing said pressure plate to pivot into said second position when said depressible member is in said open position, thereby temporarily administering a bolus flush.
