Abstract
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.
