Mass bolus administration device of the drug in patient self-management formula that has been improved

摘要

Patient self-management-type liquid drug delivery device that is configured to allow large amounts of bolus administration continued sustained and / or administration of the challenges a patient self-administration liquid drug, so as to avoid the bolus re-filled in the intake stroke before the occurrence of the pump I provide (10). Apparatus of the present invention comprises (10) includes (20) axial cavity extending through (12), said housing (18), elongated reciprocating pump housing. And a (26) displaceable wall of the second fixed wall and the first (24), a liquid drug source, the patient (34) outlet conduit, pump, connected by a (32) inlet conduit into the cavity is possible. The cavity, a closed position does not pass the liquid drug is constricted outlet conduit (34) - is not passed through a liquid agent to be narrowed displaceable outlet clamps (138), an inlet conduit (32) in the open position between displaceable inlet clamp (200) are arranged in the open position between passing the liquid in the non-constricted state the inlet conduit - a closed position.
