Patent number: 10156231Abstract: A combination of a chamber wall and the flexible membrane defines a pump chamber in a diaphragm pump. The pump chamber includes one or more internal surfaces that are modified to include a pattern of a pattern of channel surface regions. The channel surface regions provide unobstructed pathways to a respective opening disposed on an internal surface of the chamber wall. For example, as discussed herein, presence of the channel surface regions ensures that the facing of the flexible membrane does not needlessly stick (as a result of residual suction) to an inside surface of the chamber wall during a portion of the pump stroke in which negative pressure is applied to a backing of the flexible membrane. In other words, the channel surface regions distribute relief pressure along the inside surface of the pump chamber wall.Type: GrantFiled: November 13, 2014Date of Patent: December 18, 2018Assignee: Ivenix, Inc.Inventors: Jesse E. Ambrosina, Benjamin G. Powers, Alexander J. Segit, David I. Nazzaro

Publication number: 20180274533Abstract: A fluid delivery apparatus includes controller hardware, a diaphragm pump, a positive displacement pump, and a fluid conduit extending between the diaphragm pump and the positive displacement pump. During operation, and delivering fluid to a downstream recipient, the controller hardware draws fluid into a chamber of the diaphragm pump from a fluid source container. The controller hardware applies pressure to the chamber of the diaphragm pump to output the fluid in the chamber of the diaphragm pump downstream through the fluid conduit to the positive displacement pump. During application of the pressure to the chamber and outputting the fluid in the chamber of the diaphragm pump downstream, the controller hardware activates the positive displacement pump to pump the fluid from the positive displacement pump to the downstream recipient.Type: ApplicationFiled: March 24, 2017Publication date: September 27, 2018Inventors: Jesse E. Ambrosina, Benjamin G. Powers

Patent number: 10010686Abstract: A system for controlled delivery of medicinal fluid includes a fluid pathway assembly defining a fluid pathway and including means for calculating a first calculated fluid flow rate using gas laws. The fluid pathway assembly has an inline flow sensor element received within the fluid pathway movable in response to fluid flowing in the fluid pathway. A flow control device is removably attached to the fluid pathway assembly and has a sensor for sensing a position of the inline flow sensor element in the fluid pathway, the position of the inline flow sensor element being representative of a second calculated fluid flow rate. The fluid pathway assembly includes a variable flow resistor adjustable to regulate a rate of fluid flow in the fluid pathway assembly. A drive mechanism attached to the flow control device is operably coupled to the variable flow resistor when the flow control device is attached to the fluid pathway assembly.Type: GrantFiled: January 29, 2014Date of Patent: July 3, 2018Assignee: Ivenix, Inc.Inventors: Jesse E.

Publication number: 20180147342Abstract: A fluid delivery system comprises: a control interface and multiple unique loading guides. The control interface of the fluid delivery system is configured to accept a fluid pump assembly. The multiple loading guides are retractable from the fluid delivery system to retain and control movement of a facing of the fluid pump assembly to contact the control interface on the facing of the fluid delivery system. In one configuration, the control interface is disposed in a cavity of the fluid delivery system; the multiple loading guides are disposed at locations in proximity to the cavity. The multiple loading guides can be configured to slidably retract in unison to support substantially orthogonal insertion of the fluid pump assembly into the cavity of the fluid delivery system.Type: ApplicationFiled: December 22, 2017Publication date: May 31, 2018Inventors: Jesse E.

Patent number: 9849232Abstract: A fluid flow manager executing on first hardware controls a flow of fluid outputted from a fluid delivery pump to a recipient. A monitor resource, executing on second hardware operating independently of the first hardware, monitors for an occurrence of a failure condition associated with the delivery of fluid. In response to detecting occurrence of a failure condition associated with delivery of the fluid, the monitor resource generates a control output. The control output can be used to perform operations such as discontinue delivery of the fluid, notify a respective caregiver of the delivery failure, etc.Type: GrantFiled: September 24, 2014Date of Patent: December 26, 2017Assignee: Invenix, Inc.Inventors: George W.

Publication number: 20170205834Abstract: In accordance with one embodiment, a controller in a fluid delivery system controls magnitudes of pressure in a first volume and a second volume. The first volume is of a known magnitude. The second volume is of an unknown magnitude and varies. The controller estimates a temperature of gas in the first volume and a temperature of gas in the second volume based on measurements of pressure in the first volume and measurements of pressure in the second volume. The controller then calculates a magnitude of the second volume based on measured pressures of the gases and estimated temperatures of gases in the first volume and the second volume.Type: ApplicationFiled: March 24, 2017Publication date: July 20, 2017Inventors: Jesse E.
