Breath Analysis Receptor with Concentration Preserving Partial Reflow

The patent introduces a mask as an intermediary device between the breath analyzer and the test person. The mask provides the airtight seal function that the mouthpiece failed to provide, allowing unconscious or incapacitated persons to be tested. The mask acts as a mediator that collects breath samples without requiring active cooperation from the test person, thus resolving the contradiction between reliability of sealing and ease of operation.

The patent applies partial action by collecting a smaller breath sample volume (sigh breath) rather than requiring the full 0.7-1.2 liters needed by traditional methods. The mask collects breath samples during normal or slightly increased breathing, which is much faster than forced expiration. This partial sampling approach maintains sufficient measurement precision while dramatically reducing the time required for sample collection.

The patent enables self-service breath sampling where the test person's natural breathing process provides the sample without requiring forced expiration. The mask collects breath samples during normal breathing or slightly increased respiration, allowing the test person's own physiological process to serve the sampling function. This eliminates the need for additional effort while still obtaining sufficient volatile substance concentration for accurate measurement.

The patent applies segmentation by dividing the breath collection system into a reusable main body (breath analyzer) and a disposable mask component. The mask is the segment that comes into contact with the test person and can be easily replaced between uses, maintaining hygienic standards. This segmented approach provides infection protection without requiring complex replacement mechanisms, as the mask is a simple, standalone component that can be quickly swapped.
