摘要： Aspects of the present disclosure include a sensor configured to store in memory indications of sensor use information and formulas or indications of formulas for determining the useful life of a sensor from the indications of sensor use information. A monitor connected to the sensor monitors sensor use and stores indications of the use on sensor memory. The monitor and/or sensor compute the useful life of the sensor from the indications of use and the formulas. When the useful life of the sensor is reached, an indication is given to replace the sensor.

摘要： Medical devices and related systems and methods are provided. A method of estimating a physiological condition using a first sensing arrangement involves obtaining a sensor translation model associated with a relationship between the first sensing arrangement and a second sensing arrangement, wherein the second sensing arrangement is different from the first sensing arrangement, obtaining one or more measurements from a sensing element coupled to the processing system of the first sensing arrangement, determining simulated measurement data for the second sensing arrangement by applying the sensor translation model to the one or more measurements from the sensing element of the first sensing arrangement, and determining an estimated value for the physiological condition by applying an estimation model associated with the second sensing arrangement to the simulated measurement data.

摘要： A system and method for calibrating an IV pump infusion system tube comprises a fluid source, an infusion system comprising, an IV pump, a drive unit, a chamber with known constant volume, a control unit, and IV tubing with a known inner diameter tolerance, and a sensor and floating detection object. The system administers medicinal fluid, calculates the flow rate of the medicinal fluid in the chamber by measuring the time the floating detection object and medicinal fluid rises in the chamber, compares the calculated flow rate with a set flow rate of the IV pump input in the control unit prior to infusion, and adjusts the IV pump and flow rate based on the compared deviations for more accurate delivery to a patient. This configuration may provide a more precise delivery rate of medicinal fluid, preventing harm to the patient and waste of medicine.

摘要： The present disclosure relates to a method for calibrating non-invasive biometric information measured by a non-invasive biometric information measurement apparatus, and more specifically to a method for calibrating non-invasive biometric information, wherein non-invasive biometric information measured by a non-invasive blood glucose meter can be learned using continuous biometric information measured by a continuous blood glucose meter, and thereby calibrated so as to be personalized to a user, and by using the continuous biometric information, measured by the continuous blood glucose meter to calibrate uncertain non-invasive biometric information measured by the non-invasive blood glucose meter so as to be personalized to the user, the pattern of increase/decrease in user biometric information can be accurately determined from the still uncertain non-invasive biometric information.
