ABSTRACT:
A radiation source assembly is provided that is particularly apt for use in an anesthetic gas monitoring device (e.g., a gas spectrometer) to enhance maintenance of initial calibration conditions therewithin. In one embodiment a respiratory gas spectrometer includes a containment assembly that defines an internal containment area(s) within which a ceramic radiation source, an optical assembly, a sample gas assembly, and a radiation detection assembly are positioned. The radiation source assembly is provided for positioning and supporting the ceramic radiation source relative to the optical assembly within an internal containment area of the gas monitor. The radiation source assembly provides for enhanced sealing between the ceramic radiation source and adjoining componentry. The radiation source assembly is selectively retractable from the containment assembly to permit periodic servicing (e.g., replacement of the radiation source) without requiring disassembly of the gas spectrometer.
