Sealed bag for calibration of sensor measuring body fluid parameters
A recently granted patent (Publication Number: US11998918B2) discloses a sealed bag designed for containing a reference fluid used in the calibration or quality control of a sensor element that measures body fluid parameters. The bag features peripheral walls made of a first layered material, with an access port sealed by a cover made of a second layered material that is more resistant to oxidation by the reference fluid. The reference fluid itself includes various analytes such as CO2, O2, K+, Na+, Ca2+, Cl-, glucose, lactate, haemoglobin, creatinine, creatine, and urea.
The patent further details the composition and structure of the sealed bag, including the materials used for the inner and outer layers, gas barrier layers, and additional polymer layers. The bag assembly also includes a sealing element for access, a support element for stability, and an access probe for withdrawing the reference liquid. Additionally, a container is described that houses multiple bag assemblies for sensor calibration and quality control in analyzing body fluid parameters. Overall, the patent outlines a comprehensive system for maintaining the accuracy and reliability of sensor measurements through precise calibration with reference fluids contained in specialized sealed bags.
