US Patent:

7887520, Feb 15, 2011

Filed:

Mar 3, 2008

Appl. No.:

12/074331

Inventors:

Michael G. Simon - Del Mar CA, US

International Classification:

A61M 5/00

US Classification:

604248

Abstract:

A pressure compensating IV rate flow regulator having a housing with a metering port and an outlet. The flow rate is set by adjusting a flexible disk to vary the clearance between metering port and flow passageway. The controlled fluid passes to a land surrounding the outlet. A flexible control membrane having specific design and material characteristics extends across the land and will move or oscillate away or towards the outlet port in response to changes in head pressure, venous back pressure or patient movement. The resulting oscillation of the membrane serves to maintain the flow rate originally set by the clinician. The regulator is provided with safety and operational convenience features such as tactile indicators for “off” and KVO settings and has provision for use with accessory items such as a pole mount holder or anchoring device secured at the forearm or chest.

Appl. No.:

12/322476

Inventors:

Michael G. Simon - Del Mar CA, US

International Classification:

A61M 5/00

US Classification:

604246

Abstract:

A pressure compensating device includes a compensating disc located within an internal chamber of a housing. The compensating disc has a diaphragm over which fluid passes after entering the internal chamber. The diaphragm deflects in response to a pressure differential between fluid entering the internal chamber and fluid exiting the internal chamber to maintain the set flow rate of the fluid.

Appl. No.:

12/322477

Inventors:

Michael G. Simon - Del Mar CA, US

International Classification:

A61M 5/00

US Classification:

604248

Abstract:

An IV flow regulator includes a housing, a flow control disk, a screw, and a dial. The flow control disk establishes a rate of flow through the housing. The flow rate regulator further includes alignment features allowing for high volume manufacturing while also being assembled into an accurate and reliable flow rate regulator.
