Purpose and plain-language scope
The title and abstract indicate a sampling apparatus for systemic biomarkers. Per the excerpt's keyword and classification data, the device is directed to collecting a patient's breath for measurement—particularly CO2 production and metabolic rate—alongside dental/dental-procedure contexts (A61C, saliva removal classes), and uses structural elements termed a "tubular member," "main body," and "bite block" (with a "patient" as the subject). The excerpt also lists terms such as carbon dioxide, nitrous oxide, nitric oxide, oxygen, sedation/general anesthesia, and respiratory gas exchange, indicating the intended operating context is respiratory monitoring during sedated or anesthetized procedures. No independent claim text or detailed description is included in the supplied excerpt, so the precise claimed structure and method steps are not established here.
What the excerpt does not establish
The excerpt is the Google Patents front-matter and keyword/classification listing only. It does not contain the claims, abstract text, or description, so it does not establish the actual scope of any claim, the specific components, dimensions, materials, or method steps, the number or dependency of claims, or the technical problem solved in the applicant's own words. It also does not establish any legal conclusion about validity, enforceability, claim interpretation, or the accuracy of the assignee/status listing (Google itself disclaims that the legal status and assignees "may be inaccurate"). No prior-art comparison is drawn here.

Assignment history
Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
