Patent number: 8282570Abstract: A sidestream sampling system includes a sidestream gas measurement assembly and a sample cell configured to be assembled therewith. The sidestream gas measurement assembly includes a receptacle for removably receiving at least a portion of the sample cell. The sample cell is coupled to a sampling tube that is configured to communicate with an airway of an individual. When the sample cell is assembled with the sidestream gas measurement assembly, a window of the sample cell is oriented toward a corresponding source and/or detector of the sidestream gas measurement assembly to facilitate monitoring of an amount of at least one gas or vaporized material in an individual's respiration.Type: GrantFiled: February 4, 2008Date of Patent: October 9, 2012Assignee: RIC Investments, LLCInventors: David R Rich, Anthony T Pierry, Brian M Fudge, John L Sandor, John A Triunfo, Jr.

Patent number: 8252080Abstract: A filter assembly for use in sidestream gas sampling assembly. The filter assembly of the present invention includes a hydrophilic. The filter further includes a Hydrophobic member positioned downstream of the hydrophilic liner. The hydrophobic disk acts as a second line of defense against moisture reaching the sensing mechanism member that is constructed from a porous material and is situated such that gas entering the filter assembly passes through at least a portion the hydrophilic member. In a further embodiment, the filter includes a hydrophobic member positioned downstream of the hydrophilic member. The hydrophobic member acts as a second line of defense against moisture reaching the sensing mechanism in the gas sampling assembly.Type: GrantFiled: October 6, 2009Date of Patent: August 28, 2012Assignee: RIC Investments, LLCInventors: Brian M. Fudge, Patrick Tuxbury, Kirk Johnson

Patent number: 7549316Abstract: Sidestream gas sampling assembly that does not substantially degrade the waveform of expired gases. The gas sampling assembly includes a sample cell portion integrated with a filter portion for separating undesired liquid condensate from respiratory gases to be monitored. The gas sampling assembly is configured to receive expired gases through a gas sampling line, filter undesired liquid condensate from the expired gases through hydrophobic fiber elements and communicate the filtered gases to a sample chamber which is in close proximity to the filter where measurements may be taken thereof e.g., optical or infrared sensing mechanisms. The gases that are substantially free of liquid condensate are then exhausted from the sample chamber.Type: GrantFiled: September 11, 2006Date of Patent: June 23, 2009Assignee: RIC Investments, LLC.Inventors: David R. Rich, Brian M. Fudge, Patrick Tuxbury, Kirk Johnson

Patent number: 7137390Abstract: A filter assembly for use in sidestream gas sampling assembly. The filter assembly of the present invention includes a hydrophilic liner lining the inner perimeter of a housing for wicking moisture from the gases to be monitored prior to the gases reaching a sensing mechanism. The filter further includes a hydrophobic member positioned downstream of the hydrophilic liner. The hydrophobic disk acts as a second line of defense against moisture reaching the sensing mechanism. In one embodiment, the filter further include an absorbent layer positioned between the cylindrical housing and the hydrophilic layer to aid in wicking moisture from the gas stream. In a further embodiment, the hydrophobic disk is eliminated and the hydrophilic member is situated such that gas entering the filter assembly must pass through at least a portion the hydrophilic member.Type: GrantFiled: January 19, 2005Date of Patent: November 21, 2006Assignee: RIC Investments, LLC.Inventors: Brian M Fudge, John A Triunfo, Jr., David R Rich

Patent number: 6941162Abstract: An oximetry sensor that can be easily applied and attached to a portion of the body of a patient in a noninvasive manner is provided. The oximetry sensor of the present invention includes an adhesive wrap member for use with reusable pulse oximetry sensor electronics (e.g., an LED assembly and a photodiode coupled with a cable) to retain the sensor in the desired position comfortably on a patient. The adhesive member includes a release liner thereover which may include an appliqué or other member thereon, for example, instructions for use. The release liner is configured for removal from the adhesive member in at least one release liner portion subsequent to attaching of the pulse oximetry sensor electronics without disturbing such positioning.Type: GrantFiled: December 29, 2003Date of Patent: September 6, 2005Assignee: Respironics Novametrix, Inc.Inventors: Brian M. Fudge, Kimberley A. Golden, David R. Rich
