First Claim
Patent Images
1. A calibration tool for use in obtaining a zero calibration value for a fiber optic needle oxygen sensor, consisting essentially of:
- (a) an open top vial constructed from an oxygen impermeable material and defining a chamber,(b) a resealing, needle-penetrable, oxygen impermeable septa sealingly engaged over the open top of the vial, and(c) an oxygen permeable sachet containing a mass of particulate oxygen getter retained within the sealed chamber.

Abstract
A calibration tool and method of using the tool to calibrate a fiber optic needle oxygen sensor. The tool includes at least a vial sealingly covered by a septa and containing a supply of particulate oxygen getter within the chamber of the vial. The vial has an open top and is constructed from an oxygen impermeable material. The septa is resealing, needle-penetrable and oxygen impermeable. The supply of particulate oxygen getter is retained within an oxygen permeable sachet.
