Apparatus and method for extra-corporal chemical detection and monitoring

摘要

A device for detection of substances transmitted into the body surrounding environment through body boundaries including a first sensor arranged to face a body boundary surface and structured to locally detect a substance indicative of at least one targeted substance of interest transmitted through the body boundary surface in proximity of the body boundary surface of a monitored subject. The device also includes a second sensor arranged to face in an opposite direction from the body boundary surface and structured to detect in a surrounding environment at least one substance indicative of the targeted substance of interest transmitted through the body boundary surface of the monitored subject. In addition the device further include an electronic circuit structured to receive and process the signals generated by the first and second sensors, and to determine presence of the at least one targeted substance of interest.

1. A device for detection of events relating to substances transmitted into the body surrounding environment through body boundaries comprising:
at least one first sensor arranged to face at least one body boundary surface and structured to collect a plurality of body-related samples and generate at least one signal indicative of presence of at least one targeted substance of interest in a proximity of the at least one body boundary surface of at least one monitored subject, at least one second sensor arranged to face in an opposite direction from the at least one body boundary surface and structured to collect a plurality of environment-related samples and generate at least another signal indicative of presence of at least one targeted substance of interest or a substance substantially similar to or resulting from the at least one targeted substance of interest in a surrounding environment of the at least one monitored subject, wherein the at least one first sensor and the at least one second sensor have adjustable sensitivity levels, at least one electronic circuit structured to receive and process the at least one signal generated by the at least one first sensor and the at least one signal generated by the at least one second sensor, to determine by subtraction of the at least one signal generated by the at least one second sensor from the at least one signal generated by the at least one first sensor a differential reading, and to determine based on the differential reading when an event of presence of the at least one targeted substance of interest as being transpired through the at least one body boundary surface of the at least one monitored subject has occurred.
