| 20100113903 | PULSE OXIMETER SENSOR WITH PIECE-WISE FUNCTION - A memory in a sensor is used to store multiple coefficients for a physiological parameter. In one embodiment, not only are the sensor's specific calibration coefficients stored in a memory in the sensor for the formula to determine oxygen saturation, but multiple sets of coefficients are stored. The multiple sets apply to different ranges of saturation values to provide a better fit to occur by breaking the R to SpO2 relationship up into different pieces, each described by a different function. The different functions can also be according to different formulas for determining oxygen saturation. | 05-06-2010 |
| 20100037898 | TRACHEOSTOMY TUBE COMBINATION RADIAL SNAP AND BAYONET CANNULA CONNECTOR - A medical device tube having extended retention tabs with notches therein for improved coupling of an inner cannula connector to an outer cannula connector. The medical device tube comprises an outer cannula connector having retention tabs on an outer cannula connector flange attached to the proximal end of an outer cannula. The retention tabs maintain the snap ears of the inner cannula connector when the inner cannula connector is rotated whereby the notches substantially hold the snap ears. The snap ears may further be positioned in notches in the outer cannula flange when the snap ears lock onto the outer cannula connector flange. | 02-18-2010 |
| 20090221887 | PATIENT MONITORING ALARM ESCALATION SYSTEM AND METHOD - Embodiments of the present invention relate to a patient monitoring alarm escalation system and method. Specifically, embodiments of the present invention include an alarm detection device configured to measure physiological data received via a patient monitor, the alarm detection device configured to initiate an alarm in response to predefined measurements of the physiological data, and an alarm device configured to emit a first signal with a first property and a second signal with a second property, the first signal being emitted when the alarm is initiated, the second signal being emitted if an alarm acknowledgement mechanism is not activated prior to a designated event. | 09-03-2009 |
| 20090082651 | Selection of ensemble averaging weights for a pulse oximeter based on signal quality metrics - A method and a system for ensemble averaging signals in a pulse oximeter, including receiving first and second electromagnetic radiation signals from a blood perfused tissue portion corresponding to two different wavelengths of light, obtaining an assessment of the signal quality of the electromagnetic signals, selecting weights for an ensemble averager using the assessment of signal quality, and ensemble averaging the electromagnetic signals using the ensemble averager. | 03-26-2009 |
