摘要:
Exhaled breath analysis in health and disease is an area of growing clinical interest with the potential to be adopted through the whole respiratory healthcare continuum. However, currently there is no standard for exhaled breath collection, and the optimal way to preconcentrate the highly humid exhaled breath is not known. Described is an optimized combination of sorbent materials and sample handling methods that allows quantitative capturing of exhaled molecules over a broad range in highly humid conditions. The invention can be applied in pre-concentration units of future devices for exhaled breath analysis, for example at the bedside.

A system and method of monitoring sobriety using a hand-held breath testing device that, on receipt of a user's breath, generates a breath test signal comprising substance content data and user identification data, and wirelessly transmits the breath test signal to a breath test signal receiving station.

A device is disclosed for conducting a non-invasive analysis of a bodily fluid to determine the presence and level of a certain constituent carried by the bodily fluid. An indicator formulation of the device changes color in response to exposure to the constituent to provide a visible indication of the presence and level of the constituent carried by the bodily fluid. A carrier substrate of the device is constructed of a material having voids providing a high void volume within the substrate. The device is made by applying a chromagen to the carrier substrate to create a chromagen-laden carrier member. Then, a selected reagent having a particular constituent-specific formulation is applied to the chromagen-laden member. The selected reagent then combines with the chromagen thereby establishing the indicator formulation within the carrier substrate in place for reception of a sample of the bodily fluid.

It is an object to prevent impersonation in breath measurement by using a portable device. After breath is introduced into a breath introduction inlet 11 of a breath introduction device 1, a first image group is acquired by continuously capturing images over a predetermined period, and after drinking determination based on the introduced breath from the breath introduction inlet 11, the portable device is provided with an imaging device 11 that acquires a second image by capturing an image again and outputs whether or not each image in the first image group and the second image are the images of the same person.
摘要:
A gas detection device and a gas inlet module thereof are provided. The gas detection device includes a case, a flow disturbing element, a check film and a detector. The case includes a cavity and an exhaust hole. The flow disturbing element is for making a to-be-measured gas vertically enter the cavity. The check film is connected to the flow disturbing element for make the vertical to-be-measured gas flow into the cavity in one-way. The detector is disposed within the cavity and positioned between the exhaust hole and the check film for detecting a property of the to-be-measured gas. The exhaust hole is for making the to-be-measured gas be exhausted.

摘要:
A method and system for monitoring a user's intoxication including receiving a set of signals, derived from a set of samples collected from the user at a set of time points; providing a sobriety task to the user proximal to a time point of the set of time points; generating a performance dataset characterizing performance of the sobriety task by the user; receiving a supplementary dataset characterizing a demographic profile of the user and/or a physiological state of the user; determining a set of values of an intoxication metric, derived from the set of signals; generating a predicted temporal profile of the intoxication metric for the user based upon the set of values, the set of time points, and the supplementary dataset; generating an analysis of the user's sobriety based upon the performance dataset and the predicted temporal profile; and providing a notification to the user based upon the analysis.

A gas detection device and a gas inlet module thereof are provided. The gas detection device includes a case, a flow disturbing element, a check film and a detector. The case includes a cavity and an exhaust hole. The flow disturbing element is for making a to-be-measured gas vortically enter the cavity. The check film is connected to the flow disturbing element for make the vortical to-be-measured gas flow into the cavity in one-way. The detector is disposed within the cavity and positioned between the exhaust hole and the check film for detecting a property of the to-be-measured gas. The exhaust hole is for making the to-be-measured gas be exhausted.
