Publication number: 20130023775Abstract: A magnetic reusable sensor is configured to attach to a tissue site so as to illuminate the tissue site with optical radiation and detect the optical radiation after attenuation by pulsatile blood flow within the tissue site. The sensor is configured to communicate with a monitor so as to calculate a physiological parameter corresponding to constituents of the pulsatile blood flow determined by the detected optical radiation. The sensor has a reusable emitter and a detector. A disposable wrap removably secures the emitter and the detector to a tissue site via magnetically enhanced receptacles fixedly mounted on the wrap and magnetically enhanced carriers housing the emitter and the detector.Type: ApplicationFiled: July 16, 2012Publication date: January 24, 2013Applicant: CERCACOR LABORATORIES, INC.Inventors: Marcelo M.

Publication number: 20120330112Abstract: A patient monitoring system includes an inflatable cuff, a gas reservoir containing a compressed gas, and a sensor. When the inflatable cuff is coupled to a wearer, the gas reservoir supplies gas to the inflatable cuff to inflate the inflatable cuff via gas pathways. As the inflatable cuff inflates, a patient monitor can receive blood pressure data from the sensor and use the blood pressure data to determine the blood pressure of the wearer. The patient monitor can also receive blood pressure data during deflation of the inflatable cuff to determine the blood pressure of the wearer.Type: ApplicationFiled: June 19, 2012Publication date: December 27, 2012Applicant: CERCACOR LABORATORIES, INC.Inventors: Marcelo Lamego, Massi Joe E. Kiani, Ken Lam, Cristiano Dalvi, Hung Vo

Publication number: 20120283524Abstract: A monitoring device for measuring one or more physiological parameters of a medical patient can include a finger clip sensor connected to a monitor. An accelerometer in the finger clip sensor detects patient motion or movement that may interfere with monitoring. In response, the monitor displays a message alerting the patient to stop moving or a game in which the objective requires the patient to hold his or her finger still. The device can delay measurement until the patient is still enough and remains still long enough for a clear measurement.Type: ApplicationFiled: April 18, 2012Publication date: November 8, 2012Applicant: CERCACOR LABORATORIES, INC.Inventors: Abraham M. Kiani, Massi Joe E. Kiani, Marcelo M. Lamego

Patent number: 8301217Abstract: A physiological sensor is adapted to removably attach an emitter assembly and a detector assembly to a fingertip. The emitter assembly is adapted to transmit optical radiation having multiple wavelengths into fingertip tissue. The detector assembly is adapted to receive the optical radiation after attenuation by the fingertip tissue. The sensor has a first shell and a second shell hinged to the first shell. A spring is disposed between the shells and urges the shells together.Type: GrantFiled: September 28, 2009Date of Patent: October 30, 2012Assignee: Cercacor Laboratories, Inc.Inventors: Ammar Al-Ali, Chris Schultz

Publication number: 20120265039Abstract: A patient monitor capable of measuring microcirculation at a tissue site includes a light source, a beam splitter, a photodetector and a patient monitor. Light emitted from the light source is split into a reference arm and a sample arm. The light in the sample arm is directed at a tissue site, such as an eyelid. The reflected light from the tissue site is interfered with the light from the reference arm. The photodetector measures the interference of the light from both the sample arm and the reference arm. The patient monitor uses the measurements from the photodetector to calculate the oxygen saturation at the tissue site and monitor the microcirculation at the tissue site.Type: ApplicationFiled: February 9, 2012Publication date: October 18, 2012Applicant: CERCACOR LABORATORIES, INC.Inventor: Massi Joe E. Kiani

Publication number: 20120253150Abstract: The present disclosure relates to a sensor having a set of photodetectors that are arranged at various locations to enable the measurement of blood glucose. The photodetectors are arranged across multiple locations. For example, the detector may comprise multiple photodetector arrays that are arranged to have a sufficient difference in mean path length to allow for noise cancellation and noise reduction. Walls may be used in the detector to separate individual photodetectors and prevent mixing of detected optical radiation between the different locations on the measurement site. A window may also be employed to facilitate the passing of optical radiation at various wavelengths for measuring glucose in the tissue.Type: ApplicationFiled: June 15, 2012Publication date: October 4, 2012Applicant: CERCACOR LABORATORIES, INC.Inventors: Sean Merritt, Marcelo Lamego, Cristiano Dalvi, Hung Vo, Johannes Bruinsma, Jeroen Poeze, Ferdyan Lesmana, Massi Joe E.

Publication number: 20120232359Abstract: Embodiments of the present disclosure include a handheld multi-parameter patient monitor capable of determining multiple physiological parameters from the output of a light sensitive detector capable of detecting light attenuated by body tissue. For example, in an embodiment, the monitor is capable of advantageously and accurately displaying one or more of pulse rate, plethysmograph data, perfusion quality, signal confidence, and values of blood constituents in body tissue, including for example, arterial carbon monoxide saturation (“HbCO”), methemoglobin saturation (“HbMet”), total hemoglobin (“Hbt”), arterial oxygen saturation (“SpO2”), fractional arterial oxygen saturation (“SpaO2”), or the like. In an embodiment, the monitor advantageously includes a plurality of display modes enabling more parameter data to be displayed than the available physical display real estate.Type: ApplicationFiled: May 22, 2012Publication date: September 13, 2012Applicant: CERCACOR LABORATORIES, INC.Inventors: Ammar Al-Ali, Joe Kiani, Mohamed Diab, Greg Olsen, Roger Wu, Rick Fishel

Patent number: 8265723Abstract: An embodiment of the present disclosure seeks to select characteristics of incoming intensity data that cause comparisons of selected characteristics to produce defined probe off space having reduced crossover with defined probe on space. Once defined, the present disclosure compares characteristics of incoming intensity data with the now defined probe off space, and in some embodiments, defined probe on space, to determine whether a probe off condition exists. When a processor determines a probe off condition exists, the processor may output or trigger an output signal that audibly and/or visually indicates to a user that the optical sensor should be adjusted for a proper application to a measurement site.Type: GrantFiled: October 12, 2007Date of Patent: September 11, 2012Assignee: Cercacor Laboratories, Inc.Inventors: Ryan Timothy McHale, Walter M.
