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: The invention provides a flow control system well suited for use in intravenous fluid delivery systems comprising a flow restrictor wafer having one or more flow limiting flow restrictor paths formed thereon. The system provides fixed flow rate control. The system also provides means for selectively orienting at least two flow restrictor paths relative to the main fluid passage to varying the flow rate.

Abstract: The present invention provides both a continuous dose and a bolus dose of fluid or beneficial agent (26) to a patient. A source of fluid (26) is in fluid communication with a continuous flow path (290) for providing the patient with a continuous source of the beneficial agent (26). The source of beneficial agent (26) is also connected to a bolus dose apparatus (15) which provides patient control of a bolus dose of the beneficial agent (26), up to a preselected maximum.
