Abstract

A portable electronic device and a related methods are described using an portable electronic device, preferably with telecommunication capabilities to allow for data and/or voice communication via private or public networks, with an integrated gas sensor (12,21) sensitive to hydrogen and/or methane and/or carbon monoxide, and an opening (107) for a contactless delivery of a breath sample of a user to the sensor and elements configured to store a time sequence of data representative of a plurality of hydrogen and/or methane concentrations and optionally a correlation and testing unit for correlating the time sequence of concentration measurements with a time sequence of events relating to the food intake of the user and for performing tests, in particular test for food intolerances or cigarette consumption, on the correlated data.

Portable Electronic Device for Breath Sampling

ABSTRACT

          A portable electronic device and a related methods
are described using an portable electronic device, preferably
with telecommunication capabilities to allow for data and/or
voice communication via private or public networks, with an
integrated gas sensor (12,21) sensitive to hydrogen and/or me-
thane and/or carbon monoxide, and an opening (107) for a con-
tactless delivery of a breath sample of a user to the sensor
and elements configured to store a time sequence of data rep-
resentative of a plurality of hydrogen and/or methane concen-
trations and optionally a correlation and testing unit for
correlating the time sequence of concentration measurements
with a time sequence of events relating to the food intake of
the user and for performing tests, in particular test for food
intolerances or cigarette consumption, on the correlated data.

FIELD OF THE INVENTION

          The present invention relates to a portable elec-
tronic device such as a mobile phone, tablet and the like with
an integrated gas sensor configured to detect the presence of
breath components in a sample of a user's breath.

BACKGROUND OF THE INVENTION

          Portable or mobile devices originally introduced as
mobile phones or electronic agendas become more and more ubiq-
uitous. As the processing power of their internal processors
grows and equally the bandwidth for communication with sta-
tionary processors, such portable devices take on more and
more the role of multi-purpose tools available to consumers
and specialist users alike.

          It has been recognized that portable devices can
benefit from the presence of sensors capable of providing a
chemical analysis of materials brought into contact or the vi-
cinity of the device. Whilst there are many possible applica-
tions for such sensors, it suffices to consider for example
the analysis of air surrounding the portable device. Such an
analysis can be useful for multiple purposes such as testing

for hazardous gases, breath analysis for general medical pur-
poses or driving fitness, and the like.

          Specialized devices for testing the breath for ke-
tones are well known and can for example be found in the Unit-
ed States patent application 2008/0077037.

          Recently progress towards portable devices has been
reported in the NTT DOCOMO Technical Journal Vol. 14, No. 1,
51 - 57. However, the described device remains a specialized
equipment, which can communicated with remote servers only via
a separate mobile phone.

          A detection integrated in a mobile device is brief-
ly referred to in the United States patent no. 8280436 B2 pur-
porting to use infrared spectrophotometers, electrochemical
fuel cells or other gas analysers.

          It is known to use a hydrogen breath test (or HBT)
as a clinical medical diagnosis for people with irritable bow-
el syndrome, and common food intolerances. The test is simple,
non-invasive, and is performed after a short period of fasting
(typically 8-12 hours). Even though the test is normally...
