VARIABLE RATE CONTROLLED DELIVERY DRIVE MECHANISMS FOR DRUG DELIVERY PUMPS |
摘要 |
A variable rate controlled delivery drive mechanism includes a drive mechanism housing, at least partially within which initially resides a biasing member positioned in an initially energized state within an inner cavity of a piston. The drive mechanism may include a gear drive having one or more screws and one or more corresponding nuts. The piston contacts a plunger seal and is configured to axially translate the plunger seal, by force asserted upon it from the biasing member, from a first position to a second position within a drug container for drug delivery. The biasing member is metered from free expansion from its energized state by the gear drive and a gear assembly mechanism having a motor. A drug delivery pump utilizes such variable rate controlled delivery mechanisms. A status reader configured to recognize one or more corresponding status triggers is utilized to provide feedback to a user. |
