摘要： A single or multilumen intravenous catheter that may include an integral biosensor having an active portion exposed through a sensing port formed in a distal portion of an outer wall of the catheter. The biosensor may be formed on a flex circuit mounted to a support member or probe that displaces the active portion from an inner wall of the catheter for protection from friction during installation through a lumen. The support member or probe may position the biosensor concentrically within the lumen or against an inner diameter of the outer wall. The biosensor may be sealed about the sensing port to prevent passage of fluid therethrough, or a proximal end of the sensing port may remain open to allow flushing of the biosensor with saline infused through the lumen.

摘要： There are provided methods of packaging and packages that prevent damage of the package contents while maintaining sterility and that limit the negative effects of sterilization on sensors such as enzyme sensors. A method of packaging an enzyme sensor includes providing an enzyme sensor such as a glucose oxidase sensor in a gas impermeable package comprising one or more of oxygen and water, removing a significant portion of the oxygen and water present in the package, and sealing the package. The resulting package comprises the enzyme sensor in an atmosphere that is substantially free of oxygen and water. The package can also include a pressure indicator that indicates when the package has exceeded a predetermined pressure.

摘要： A temperature compensation method for an enzyme electrode by measuring an operating temperature of the enzyme electrode, measuring the current generated by the enzyme electrode, determining a deviation in measurement between the current generated and a reference current at the operating temperature, determining an enzyme concentration corresponding to the measured current, and calibrating the enzyme concentration to compensate for the deviation in measurement.
