Filed:

Nov 15, 2010

Appl. No.:

12/946851

Inventors:

Saket S. Bhatia - Santa Clara CA, US
Darrell E. Davis - Sunrise FL, US
Ankush S. Bhatia - Mumbai, IN

International Classification:

G08B 23/00

US Classification:

3405735, 3405731, 340540

Abstract:

In one example embodiment, an alarm unit for monitoring or detecting presence of an analyte on an analyte sensor comprises a square plastic casing protecting the alarm electronics portion and including a signal processing means, a clip attachment means configured to be separated and attached from the casing and used to attach the unit to clothing. The clip attachment has enough clearance to be used with thick articles of clothing including diapers and has a set of teeth frictionally held against a rubber strip portion located on the casing back so as to also enable secure attachment to very thin articles of clothing. The alarm unit may further comprise a three-way switch located externally for easy alarm chime and alarm volume selection. Interdependent modes of operation may enable the signal processing means to control the alarm unit operation and features including low power indication, improper cable plug installment, three-way switch deactivation during Monitor mode, and a snooze/reset feature by which the alarm is disabled temporarily so that, as an example, a user can focus on running to the bathroom where the device is used to treat enuresis.

Abstract:

An alarm unit for monitoring or detecting presence of an analyte on a separate sensor portion. The present invention comprises only the alarm unit and its means for attachment to a user's clothing. A square plastic casing protects the alarm electronics portion including a signal processing means. A large clip attachment means is included that is easily separated and attached from the casing and is used to attach the unit to clothing and which has enough clearance to be used with thick articles of clothing including diapers and which has a set of teeth frictionally held against a rubber strip portion located on the casing back so as to also enable secure attachment to very thin articles of clothing. A three-way switch is located externally for easy alarm chime and alarm volume selection. Interdependent modes of operation enable the signal processing means to control the alarm unit operation and features including low power indication, improper cable plug installment, three-way switch deactivation during Monitor mode, and a snooze/reset feature by which the alarm is easily disabled temporarily so that, as an example, a user can focus on running to the bathroom where the device is used to treat enuresis.

Assignee:

Theos Medical Systems, Inc. - Santa Clara CA

International Classification:

G01N 27/403

US Classification:

20440301

Abstract:

An electrolyte sensor that uses conductive elastomer electrodes. Examples of the intended analytes for sensor use include those found in urine, saliva, blood, feces and spinal fluid, although other analytes exist for electrolyte detection. Conductive elastomer trace electrodes are separated by a gap or channel which can be bridged by an electrolyte and thereby complete an electrical circuit to an alarm or other circuitry. Gap or channel distances vary the level of electrical resistance associated with detecting certain analytes.
