Estimating the term…
A system is provided for sensing an analyte in a breath sample. The system includes a breath bag, a cartridge and a base. The breath bag contains the breath sample. The bag includes a mouthpiece fixedly disposed on the breath bag. The cartridge includes an interactant that reacts with the analyte and generates a change in an optical characteristic relative to a reference. The base includes a flow path, a breath bag receiver for detachably receiving and retaining the mouthpiece of the breath bag in fluid communication with the flow path, and a cartridge receiver that detachably receives and retains the cartridge in the base, such that the base engages the cartridge so that the interactant is in fluid communication with the flow path. The base further includes a flow handling system in fluid communication with the flow path, an optical subsystem for sensing the change in the optical characteristic, a processor operatively coupled to the flow handling system and the optical subsystem, and a user interface operatively coupled to the processor and comprising a start command. Upon user selection of the start command, the processor is configured to automatically regulate the flow handling system to move the breath sample in the flow path and to contact the breath sample and the interactant. Upon the occurrence of a predetermined process parameter, the processor is configured to automatically regulate the optical subsystem to sense the change in the optical characteristic, to correlate the sensing of the optical system with information about the analyte in the breath sample, and to output the information about the analyte in the breath sample to the user interface. Related methods also are provided.
A system for sensing an analyte in breath of a patient, the system comprising:
A method for sensing an analyte in breath of a patient, the method comprising:
A system for sensing an analyte in breath of a patient, the system comprising:
A cartridge for use in sensing an analyte in breath of a patient using a base, wherein the base comprises a flow path for flow of the breath within the base, a breath input receiver in fluid communication with the flow path that receives the breath and directs the breath into the flow path, a cartridge housing that detachably receives the cartridge into the base, and an optical subsystem that senses the optical change and generates an output comprising information about the analyte in response to the optical change, the cartridge comprising a reaction volume and a shroud that is opaque to ambient light, wherein the cartridge is configured to be detachably disposed in the cartridge housing so that reaction volume is in fluid communication with the flow path to receive the breath, wherein flow of the breath through the reaction volume facilitates an optical change to the reaction volume in relation to at least one of a presence and a concentration of the analyte, and wherein the shroud of the cartridge mates with the cartridge housing of the base to block ambient light from impinging on the reaction volume.
