Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive, remarkably movable and easy to use device and system for both the steady-state feed of a useful medicine and patient-controlled replenishment as to the useful medicine. SOLUTION: The device for distributing liquid comprises a means for providing a source of liquid under pressurization, a means in fluid communication with the source of liquid for adjusting the steady-state flow rate of the liquid, a bolus dosing means also in fluid communication with the source of liquid for providing a liquid-controllable dose of bolus, and a downstream capillary means in fluid communication with an adjustment means and the bolus dosing means.

Abstract: PROBLEM TO BE SOLVED: To provide a device and a system for both of the constant feeding of a useful drug and a controlled replenishment of the useful drug to a patient, which are inexpensive, extremely movable, and easy to use. SOLUTION: This device for the dispensation of a liquid is constituted of a bolus dosing means and a thin tube means for flowing-down. In this case, the bolus dosing means is under a fluid-communicating state with a liquid source-providing means under a pressurized state, a means to regulate a constant flow rate of a liquid which is under a fluid-communicating state with a liquid source, and also, the liquid source to provide a controllable bolus dosing with the liquid. In the meantime, the thin tube means for flowing-down is under a fluid-communicating state with the above regulating means and the bolus dosing means.

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: Infusor Having Distal Flow Regulator An infusor (10) is disclosed for dispensing a liquid under pressure at a predetermined flow rate. The infusor (10) includes a housing (12) containing an elastomeric bladder (16) for receiving the liquid under pressure. The liquid is delivered from the bladder to a patient through tubing (36). A non-adjustable, preselected flow regulator (38) includes a capillary bore (48). The flow regulator (38) is disposed at the distal end of the tubing (36), such that the tubing may be primed quickly, in a time period virtually unaffected by the flow regulator (38). Distal placement of the flow regulator (38) results in a more constant temperature, and thus a more constant flow rate, of fluid flowing through the flow regulator.
