Gas sampling device
The technology disclosed herein relates to, in part, a gas sampling device. According to some aspects, the gas sampling device has a housing defining an airflow aperture, a gas testing chamber and an airflow pathway extending from the airflow aperture to the gas testing chamber. The housing also defines a sensor receptacle configured to removably hold a disposable sensor test strip within the gas testing chamber and a docking structure configured to be received by a docking station.
1. A gas sampling device comprising:
a housing, the housing defining: an airflow aperture, a gas testing chamber,
a sensor receptacle disposed along a long axis of the housing and within an airflow pathway within the gas testing chamber, the sensor receptacle configured to slidably receive a disposable sensor test strip within the gas testing chamber, the airflow pathway extending from the airflow aperture to the gas testing chamber,
a docking structure configured to be physically received within a docking station;
a heart rate sensor disposed on an exterior surface of the housing and configured to measure heart rate data from a fingertip of a patient: and
the disposable sensor test strip comprising a plurality of discrete binding detectors disposed thereon.
2. The device of claim 1 , further comprising a one-way valve disposed across the airflow pathway between the airflow aperture and the gas testing chamber.
3. The device of claim 1 , further comprising a conditioning element in communication with the airflow pathway between the airflow aperture and the gas testing chamber.
4. The device of claim 3 , wherein the conditioning element is a filter element disposed across the airflow pathway.
5. The device of claim 3 , wherein the conditioning element is a gas source in fluid communication with the gas testing chamber.
6. The device of claim 3 , wherein the conditioning element is a heating element disposed along a portion of the airflow pathway.
7. The device of claim 1 , wherein the housing further defines an inhalation inlet and an inhalation pathway extending from the airflow aperture to the inhalation inlet, wherein a VOC-filter is disposed across the inhalation pathway.
8. The device of claim 7 , further comprising a one-way valve disposed across the inhalation pathway between the inhalation inlet and the airflow aperture.
9. The device of claim 1 , wherein the docking structure is configured to define an interference fit with the docking station.
