Dean L Kamen: Flow control system using boyles law. Bruce D Sunstein, Kay H Pierce, Paul C Flattery, October 18, 1988: US04778451 (244 worldwide citation)

A dispensing arrangement in a fluid line that isolates a region of fluid in the line from pressure effects in the line outside the region. A housing of measuring fluid surrounds the region so that changes in the measurement fluid pressure cause changes in the pressure of the original fluid in the re ...

Dean L Kamen: Infiltration detection system using pressure measurement. Bruce D Sunstein, Mary R Jankousky, March 28, 1989: US04816019 (122 worldwide citation)

A system is provided for detecting the presence of an infiltration condition in a line delivering fluid to a patient. Stepping means subjects the fluid in the line to a negative pressure step. The pressure of the fluid is monitored, and processing means then determines whether an infiltration condit ...

Dean L Kamen: Fluid flow control system. Baxter Travenol Laboratories, Bruce D Sunstein, Kay H Pierce, Paul C Flattery, October 18, 1988: US04778450 (62 worldwide citation)

In a fluid flow control system a weight comparator compares the weight of fluid in a reservoir with a weight reference that is programmed to decrease at a desired rate. A fluid flow comparator compares the actual fluid flow rate with a programmed fluid flow rate and operates directly on a flow contr ...

Dean L Kamen: Device for preserving continuity of intravenous flow. Baxter Travenol Laboratories, John A Caruso, Paul C Flattery, Bruce D Sunstein, May 22, 1984: US04449976 (35 worldwide citation)

A device for reducing the rate of flow from a reservoir as the reservoir empties requires only a single chamber having an input, for receiving fluid from a reservoir, and an output port. There is a provision for sensing fluid level in the chamber, and a separate provision for reducing the flow throu ...
