Abstract: An apparatus (60) and system (20) are disclosed for the patient-controlled delivery of an analgesic or other beneficial agent 142, while preventing administration of a toxic quantity of the beneficial agent. The invention permits delivery of fractional doses to a patient in quantities which are directly proportional to the time period since the last dose or fraction thereof was delivered to the patient. In the preferred embodiments the apparatus includes a housing (58) including a casing (88) and a back plate (86), the housing containing a control switch (84) for opening and closing downstream conduit (62) and for depressing a floating plate (100) that thereby compresses a dose reservoir (90) with the beneficial agent (142) therein. A spring (124) biases the control switch (84).

Abstract: A vacuum biased disposable infuser is provided having a liquid chamber (14) and at least one vacuum chamber (44). The liquid chamber (14) includes a liquid plunger (26) contained therein while the vacuum chamber (44) includes a vacuum plunger (48). The plungers (26, 48) are connected by an arm such that when liquid under pressure is provided to the liquid chamber (14), the vacuum plunger (48) is drawn back in the vacuum chamber (44). The device is further preloaded such that at the end of infusion, the vacuum plunger (48) does not abut against the vacuum chamber (44).
