ROTATIONAL METERING PUMP FOR INSULIN PATCH

A rotary pump for a fluid metering system is provided. The rotary pump reciprocates, and is reversed by a signal from a limit switch that is deflected by an actuator arm on a rotating sleeve of the pump system. The rotary pump includes a plunger and optional stopper formed from a two-shot molding pr...

Beschreibung
Zusammenfassung:	A rotary pump for a fluid metering system is provided. The rotary pump reciprocates, and is reversed by a signal from a limit switch that is deflected by an actuator arm on a rotating sleeve of the pump system. The rotary pump includes a plunger and optional stopper formed from a two-shot molding process, and including seals overmolded onto the head of the plunger and the head of the optional stopper. L'invention concerne une pompe rotative pour un système de dosage de fluide. La pompe rotative effectue un mouvement de va-et-vient et est inversée par un signal provenant d'un commutateur de fin de course qui est dévié par un bras d'actionneur sur un manchon rotatif du système de pompe. La pompe rotative comprend un piston et un bouchon facultatif formé à partir d'un processus de moulage en deux étapes et comprenant des joints surmoulés sur la tête du piston et la tête du bouchon facultatif.
