    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).
