Abstract
An injection apparatus has a medicament container whose hollow interior is subdivided by a partition into a medicament compartment housing a body of the liquid medicament and a pressurizable compartment. A positive-displacement pump has an intake connected via a conduit to the medicament compartment and is operable to pass a liquid from this intake to its output. A needle is provided on the output so that when implanted in a person this pump can be used to inject a predetermined carefully metered quantity of the medicament into the person.
