Patent number: 8240325Abstract: A gas regulator includes a housing and a pressure regulator positioned within the housing along a first axis for controlling the pressure of gas received from a pressurized source. A flow meter controls the flow rate of the gas received from the pressure regulator. The flow meter is positioned relative to the housing along a second axis, transverse to the first axis. An outlet nozzle member has a nozzle stem and is positioned along the first axis. The outlet nozzle member receives the gas from the flow meter and delivers the gas through the nozzle stem.Type: GrantFiled: August 24, 2009Date of Patent: August 14, 2012Assignee: Inovo, Inc.Inventors: LeNoir E. Zaiser, Kevin Confoy

Publication number: 20100212669Abstract: A gas regulator includes a delivery valve assembly having a delivery outlet and a delivery valve member engageable with the delivery outlet for controlling flow of a gas from a gas source. A timing gas chamber receives gas from the gas source. Gas pressure within the timing gas chamber controls the operation of the delivery valve member. An adjustment system controls the amount of time required for the gas to fill the timing gas chamber so as to control the length of time that the delivery valve assembly is opened to conserve gas. In other embodiments, a capacity adjustment system can adjust the capacity of a gas reservoir system.Type: ApplicationFiled: May 3, 2010Publication date: August 26, 2010Applicant: INOVO, INC.Inventors: LeNoir E.

Publication number: 20100108068Abstract: A gas regulator includes a slave valve assembly for receiving and controlling the flow of gas to a desired destination. A timing chamber is positioned adjacent to the slave valve assembly. The timing chamber has an inlet for also receiving the gas. An electronically operated pilot valve assembly is in communication with the timing chamber for operating the slave valve assembly. When the pilot valve assembly is closed, gas pressure within the timing chamber acting on the slave valve assembly closes the slave valve assembly. When the pilot valve assembly is open, gas exits the timing chamber and reduces the gas pressure in the timing chamber, thereby allowing the slave valve assembly to open and deliver the gas to the desired destination.Type: ApplicationFiled: September 21, 2009Publication date: May 6, 2010Applicant: INOVO, INC.Inventors: LeNoir E.

Publication number: 20080234680Abstract: Individual plate sections of a dynamic bone fixation plate can be internally interlocked to maintain the assembled plate and to limit relative motion between the sections. A dynamic bone fixation plate can include a first plate section, a second plate section, and a compressible interlock member. The first plate section includes a first joint structure and the second plate section includes a second joint structure, where the second joint structure can be dynamically mated with the first joint structure. The compressible interlock member can be disposed within the first joint structure and the second joint structure to limit relative motion of the first joint structure and the second joint structure.Type: ApplicationFiled: January 25, 2008Publication date: September 25, 2008Applicant: STRUCTURE MEDICAL, INC.Inventors: LeNoir E.

Patent number: 6986350Abstract: A gas flow regulator includes a one-piece housing with an internally disposed flowmeter. The flowmeter is screwed into the housing. A fitting, such as a hose barb, extends through the housing and into the body of the flowmeter to secure the pieces together. Similarly, an inner core assembly can be separately fabricated, screwed into the housing and secured by fittings. This allows a full brass core for oxygen regulators.Type: GrantFiled: November 17, 2003Date of Patent: January 17, 2006Inventors: LeNoir E. Zaiser, Kevin Confoy

Publication number: 20050042111Abstract: A pump including a first piston positioned within a first chamber having a first inlet and a first outlet. A second piston is positioned within a second chamber and is secured to the first piston. The diameter of the first piston is larger than the diameter of the second piston. The second chamber has a second inlet and a second outlet. The second inlet is in communication with the first outlet of the first chamber. A drive system reciprocates the first and second pistons in unison within the first and second chambers such that fluid is pumped into the first chamber, from the first chamber to the second chamber, and then expelled from the second chamber.Type: ApplicationFiled: February 4, 2004Publication date: February 24, 2005Inventors: LeNoir Zaiser, Kevin Confoy

Publication number: 20040194829Abstract: A differential pressure valve is used to deliver a medical gas such as oxygen to a patient. A movable slave diaphragm operates to open and close a gas passageway in response to the patient's inhalations. In particular, the slave diaphragm opens and closes a nozzle that is pressurized by stored oxygen in a gas reservoir. The diaphragm is pneumatically controlled in response to the patient's inhalation. The nozzle is sized so that the forces exerted on the diaphragm on the nozzle side of the diaphragm nearly balance the forces exerted on the opposing (timing gas chamber) side of the diaphragm. Furthermore, the nozzle includes a filter element.Type: ApplicationFiled: September 19, 2003Publication date: October 7, 2004Inventors: LeNoir E. Zaiser, Kevin Confoy

Patent number: 6510747Abstract: Semi-spherical supports are used in the piercing of small, consistently sized holes in a soft metal. In particular, a flow control device, such as an orifice plate, can be fabricated with small, consistently sized flow apertures to regulate flow in a gas flow regulating device. By using semi-spherical supports, the need for hand-punching and real-time flow calibration can be avoided and automated machinery with a tapered piercing tool can be used to fabricate the flow control device.Type: GrantFiled: April 24, 2000Date of Patent: January 28, 2003Assignee: Inovo, Inc.Inventors: LeNoir E.
