Patent number: 8460203Abstract: A gas flow diverter for increasing the turbulence of an incoming respiratory gas flow through a respiratory gas sensor is provided. The diverter is positioned at a patient or inlet end of a tube section of the sensor in order to divert the respiratory gas flow from the patient generally equally across the cross-sectional area of the tube section. The diverter can be formed integrally as a part of the sensor, or can be releasably attached to the sensor or to an adapter that is releasably connected to the inlet end of the sensor for use in situations in which the volume of the incoming respiratory gas flow from the patient is greatly reduced due to the size of the patient, i.e., when the patient is an infant.Type: GrantFiled: December 20, 2010Date of Patent: June 11, 2013Assignee: Treymed, Inc.Inventor: Robert H.

Patent number: 8459261Abstract: A side-stream respiration monitoring system includes a sensor, a monitor, and a display. The sensor is constructed to engage respiration flows having a variable flow amounts and acquire a respiration sample from the flow. The monitor is connected to the sensor and configured to determine the amount of respiration flow as well as the amount of several constituents of the respiration flow such as oxygen, carbon dioxide, water, and nitrous oxide. The monitor is also configured to adjust the determined values for ambient environment variations and is self-calibrating with respect to the ambient conditions. The monitor temporally aligns the acquired data to account for dead-space respiration events and physiological respiration modifications such as cardiac events. Information generated by the monitor is communicated to an operator via a display configured to display the real-time respiration performance.Type: GrantFiled: November 16, 2006Date of Patent: June 11, 2013Assignee: Treymed, Inc.Inventors: Robert H.

Patent number: 5616158Abstract: A moisture absorbing media filter includes a housing into which a moisture absorbing material is placed, an end cap fabricated from a clear plastic fits over the housing, exhalations pass through the end cap into an impermeable tube which terminates at substantially the middle of a bore contained in the moisture absorbing material. A tapered chamber follows the impermeable tube and terminates at the end of the moisture absorbing material, a reduced passage follows a pellet filter and leads to an outlet opening, a dyeing agent is deposited into the tapered chamber, a predetermined amount of low vapor pressure, water soluble liquid is also deposited into the tapered chamber. Exhalations enter the inlet opening and pass through the impermeable tube into the tapered chamber, low vapor pressure, water soluble liquid deposited in the tapered chamber allows moisture in the gas to be absorbed by the moisture absorbing material but not the gas itself.Type: GrantFiled: May 15, 1995Date of Patent: April 1, 1997Assignee: Pryon CorporationInventors: Bruce S.

Patent number: 4997463Abstract: A gas-liquid separator apparatus and device, particularly for use in connection with medical gas analyses, such as capnography, is provided. The separation chamber tapers in a direction from the blow down port to the dry gas outlet port providing increased surface area in the lower portion of the separation chamber for providing capillary volumes or regions. A solid body is disposed in the separation chamber to provide a surface of the capillary volumes and to decrease the effective volume of the separation chamber. The body can be used to occlude the dry gas outlet port upon tipping of the separation chamber at greater than a predetermined angle. A number of internal fins extend inwardly from the side wall and bottom surface into the separation chamber to form capillary volumes in cooperation with the side wall, bottom surface and/or solid body.Type: GrantFiled: May 11, 1990Date of Patent: March 5, 1991Assignee: Frederick William RicciardelliInventor: Robert H.

Patent number: 4713095Abstract: A gas/liquid separator for a gas analyzer includes a separation chamber having a spherically domed upper wall and a pyramid-shaped lower wall. An incoming sample to be separated is introduced into the separation chamber at one corner of the pyramid via an inlet port, liquid is removed via a liquid outlet port at the apex of the pyramid, and gas is removed via a gas outlet port in the domed upper wall. The pyramid forms internal corners, some of which converge smoothly toward the liquid outlet port so as to channel liquid away from the gas outlet port. All internal corners are separated from the gas outlet port by more than 0.05 inches in order to reduce any tendency of liquid which was collected in the internal corners to bridge across to the gas outlet port.Type: GrantFiled: October 16, 1986Date of Patent: December 15, 1987Assignee: Criticare Systems, Inc.Inventor: Robert H.

Patent number: 4644957Abstract: A biological monitoring probe carrier incorporating a spiral retaining coil is easily put in place by a drive wrench passing through a guide channel with a longitudinal slot. Said channel holds the probe carrier near its distal end and holds a monitor cable alongside a shaft of the drive wrench which includes means for engaging the probe carrier to turn and advance it for the purpose of securing to tissue the retaining coil embedded in the distal end of the carrier. The proximal end of the wrench shaft includes a manipulating means for advancing the wrench a predetermined distance once the guide channel is placed against the tissue. The drive wrench is then withdrawn and the cable may then be released as the guide channel is withdrawn by allowing the cable to slip freely through the slot without need for disconnecting the monitor apparatus from the proximal end of the monitor cable.Type: GrantFiled: April 8, 1985Date of Patent: February 24, 1987Inventors: Robert H.

Patent number: 4592368Abstract: A protection system for a gas analyzer is described which monitors gas pressure adjacent a sample cell included in the analyzer. The sample cell is connected via a gas/liquid separator to an input sample conduit. The measured pressure indicates when the separator is clogged with excessive liquid. A control circuit is provided which responds to selected pressure conditions by automatically controlling the valve to interrupt the flow of gas from the separator to the sample chamber. In this way, the sample chamber is protected against contamination by liquid. In the preferred embodiment, the sample chamber and the separator are automatically backflushed to remove any water contamination.Type: GrantFiled: October 11, 1983Date of Patent: June 3, 1986Assignee: Biochem International Inc.Inventors: Robert H.
