20090188811 | PREPARATION AND MAINTENANCE OF SENSORS - Apparatus and methods are described for preparing, maintaining, and stabilizing sensors. The apparatus and methods for preparing sensors for use are utilized in advance of the sensor being removed from a sealed, sterilized package. The apparatus include packaging materials having electrical circuits capable of stabilizing a sensor to prepare the sensor for use. The methods for preparing a sensor for use includes methods of providing a solution to a sterilized packaging that contains a sensor connected to a sensor activating circuit, activating the circuit, and allowing the sensor to stabilize. These methods can be performed without compromising the packaging. The apparatus for stabilizing a sensor that is in use include a circuit connectable to the sensor that provides a signal to the sensor that prevents the sensor from becoming destabilized when disconnected from a monitoring device. | 07-30-2009 |
20110208013 | Body Parameter Sensor and Monitor Interface - A system for sensing a physiological parameter in a human or animal, and storing a processed sensing signal at a sensor with which the sensing was performed. The system includes a physiological sensor adapted to output a sensor signal representative of a sensed physiological parameter, for processing by a remote processor. A microcontroller has memory, and is located locally to the sensor and is fixedly attached to or housed together with the sensor. An authentication algorithm is stored in the memory and the microprocessor is configured to engage in an authentication process to authenticate the sensor when queried by a remote processor. The memory is configured to receive and store data representative of a sensed physiological parameter after data from the sensor has been processed by a remote processor. The microcontroller may be configured to communicate with a remote processor over a single wire by, for example, using a single wire protocol. | 08-25-2011 |

20130228002 | CALIBRANT INFUSION FLUID SOURCE PREPARATION - Methods and systems for preparation of calibrant infusion fluid sources are disclosed. In one embodiment, a precise volume of glucose is injected into a saline-solution filled calibrant infusion fluid source proximate in time to conducting a calibration procedure. The glucose concentration in the calibrant infusion fluid source is subsequently calculated based on the measured weight of the saline-solution, as determined prior to glucose injection, and the volume of glucose injected. This method provides a highly accurate and convenient manner for use in a hospital environment, for example, with an intravenous blood glucose sensor system. In another embodiment, a premixed calibrant infusion fluid source is provided that includes saline solution and a predetermined concentration of glucose. In such embodiments, shelf life problems related to water evaporation are mitigated by hermetically covering or otherwise hermetically containing the calibrant infusion fluid source up until the point of use. | 09-05-2013 |
20140221911 | CLOT DETECTION BASED ON SIGNAL-TIME HISTORY DIAGNOSTICS - The present disclosure provides a sensor system that includes a blood access device, a flow controller, and an analyte sensor. The system is configured to flush or draw a volume of fluid through the blood access device at least once; determine a signal-time history corresponding to signals received from the sensor; determine a duration of a portion of the signal-time history; determine whether the duration is greater than a predetermined threshold value; and detect the occlusion in the blood access device when the duration is greater than the predetermined threshold value. | 08-07-2014 |
