Abstract
A system for injecting a fluid medicament into a patient includes a drive mechanism, and a cassette loaded with a pre-filled hypodermic syringe. When the cassette is loaded, the syringe is held firmly inside and the cassette can be selectively engaged with the drive mechanism. The drive mechanism has two motors. A first motor initially moves the hypodermic syringe from a position inside the cassette where its needle is concealed, to a position where the needle extends from the cassette for insertion into a patient for an injection. With the needle inserted, a second motor pushes the syringe stopper to expel a fluid medicament from the syringe. After an injection, the first motor withdraws the syringe back into concealment inside the cassette, to again firmly hold the syringe on the cassette. The cassette and syringe, in combination, can then be removed from the drive mechanism and discarded.
