DRUG INJECTION APPARATUS

摘要

A disposable cassette (12) for use with a main infusion pump unit (10) which contains both a disposable pump (20) and a battery (22), thereby requiring the simultaneous replacement of both the pump (20) and the battery (22). A controller (16) contained in the main pump unit (10) controls a prime mover (14) which drives the pump (20) and also includes a timer (78) which prevents the cassette (12) from being used for longer than a predetermined time, which is substantially less than the life of the battery (22). An interlock system prevents a cassette (12) from being reinstalled following a single use.
