Restech Earns Patents for Real-Time Sensing of Airway pH and Other
Breath Chemistries
SAN DIEGO – Sept. 12, 2006 – Restech (Respiratory Technology
Corporation) announced today<
that U.S. patent number 7,101,341 has been issued for real-time
sensing of airway pH and other
breath chemistries. The U.S. Patent and Trademark Office (USPTO)
now affords protection of
Restech’s Dx–pH Measurement System™ technology
for measuring the pH of acid reflux in the
airway, also referred to as laryngopharyngeal reflux (LPR).
Two further patents that protect the pH sensor
technology used in the Dx–pH Measurement
System have been allowed and are in the process of being issued
by the USPTO. Restech has also filed
for international patent protection.
These and other Restech patents are licensed under
agreement from Sierra Medical Technology, Inc. of
Poway, California.
Currently, a total of 12 domestic and international patent applications
have been filed. The patents cover the areas of pH sensor technology,
respiratory monitoring and therapy, as well as specific novel technologies
that enable the Dx–System to function in its unique environment.
Restech’s patent attorney, Michael Klicpera, of Patent Technology,
Inc. asserts, “Restech’s
success with domestic patent allowance and issuance should greatly
influence the likelihood of
international allowance.”
The Dx–Probe™, with its miniature sensor is the core
of the Dx–pH Measurement System,
enabling detection of aerosolized reflux in the patient’s
airway associated with asthma, sleep
apnea, COPD and other respiratory diseases.
Standard pH catheters are designed with a large gap between the
pH sensor and a reference
electrode, requiring this gap to be bridged by liquid in order
to yield a pH value. These catheters
are intended for use in the esophagus, where there is an adequate
amount of liquid to bridge this
gap. The teardrop shaped Dx–pH Probe is constructed with
a gap of only 2/1000 of an inch between the pH sensor and reference
electrode. Because its sensor is self-condensing
and does not require
immersion in liquid, the Dx–pH Probe is able to rest in the
upper airway and reliably collect pH
data.
Restech is a leader in engineering world-class medical technologies
that provide comfortable,
reliable solutions to assist physicians in the diagnosis of reflux
related health problems. For more
