20080319299 | METHOD AND APPARATUS FOR CONTROLLING POSITIONING OF A NONINVASIVE ANALYZER SAMPLE PROBE - The invention relates generally to a probe interface method and apparatus for use in conjunction with an optical based noninvasive analyzer. More particularly, an algorithm controls a sample probe position and attitude relative to a skin sample site before and/or during sampling. For example, a sample probe head of a sample module is controlled by an algorithm along the normal-to-skin-axis. Preferably, the sample probe head is positioned in terms of 3-D location in the x-, y-, and z-axes and is attitude orientated in terms of pitch, yaw, and roll. Further, attitude of the probe head is preferably orientated prior to contact of the sample probe head with the tissue sample using indicators, such as non-contact distance feedback from capacitance sensor, contacting or non-contacting optical sensors, and/or contact electrical sensors. | 12-25-2008 |
20080319382 | METHOD AND APPARATUS FOR COUPLING A CHANNELED SAMPLE PROBE TO TISSUE - Sampling is controlled in order to enhance analyte concentration estimation derived from noninvasive sampling. More particularly, sampling is controlled using controlled fluid delivery to a region between a tip of a sample probe and a tissue measurement site. The controlled fluid delivery enhances coverage of a skin sample site with the thin layer of fluid. Delivery of contact fluid is controlled in terms of spatial delivery, volume, thickness, distribution, temperature, and/or pressure. | 12-25-2008 |

20110152830 | Systems and methods for managing and delivering patient therapy through electronic drug delivery systems - In example methods and systems described, a medical device can store information locally and in a separate database on a server, for example. If the device fails, or a patient is moved to a second device, information may be transferred to the second device such that the second device can resume a complex therapy at a point where the initial medical device left off. The data necessary to restart the complex therapy system may include certain underlying patient-specific parameters according to a model capturing the patient's physiological response to the medication in question. As a result, it is not necessary for the second device to restart the complex therapy or regress to an initial set of baseline assumptions. | 06-23-2011 |

20130158504 | SYSTEM FOR MONITORING AND DELIVERING MEDICATION TO A PATIENT AND METHOD OF USING THE SAME TO MINIMIZE THE RISKS ASSOCIATED WITH AUTOMATED THERAPY - A system and method for monitoring and delivering medication to a patient includes a controller that has a control algorithm and a closed loop control that monitors the control algorithm. A sensor is in communication with the controller and monitors a medical condition. A rule base application in the controller receives data from the sensor and the closed loop control and compares the data to predetermined medical information to determine the risk of automation of therapy to the patient. The controller then provides a predetermined risk threshold where below the predetermined risk threshold automated closed loop medication therapy is provided. If the predetermined risk threshold is met or exceeded, automated therapy adjustments may not occur and user/clinician intervention is requested. | 06-20-2013 |
20130165901 | SYSTEMS AND METHODS FOR DETERMINING INSULIN THERAPY FOR A PATIENT - In example methods and systems described, insulin therapy for a patient can be determined. At least one of a short-acting subcutaneous insulin dosage recommendation, a correction subcutaneous insulin dosage recommendation, an intravenous insulin dosage recommendation, a recommended amount of carbohydrates to be administered to the patient, or combinations thereof, can be determined. In addition, information indicating a confirmation of a nutrition intake for the patient, and a long-acting insulin-on-board for the patient can be received, and based on this information, a required long-acting subcutaneous or intravenous insulin dosage for the patient can be determined. The short-acting subcutaneous or intravenous insulin dosage recommendation can be adjusted based, at least in part, on a difference between the long-acting insulin-on-board and the required long-acting subcutaneous or intravenous insulin dosage. | 06-27-2013 |
