What if a Capsule Sensor should leak while ingested?
VitalSense ingestible capsule shells are composed of inert plastic and
medical grade plastic adhesive. Each capsule is individually inspected to
insure a complete seal at the factory. VitalSense capsules have been tested
for resistance to moisture, varying pH levels, heat, enzyme reaction,
saline, and alcohol exposure. We know of no condition within the
alimentary tract that could lead to a breach of the capsule seal. However,
as an added precaution, the circuits within the capsule are further coated
with a plastic, water-resistant coating. Finally, the components within the
capsule would pass through the digestive system without noticeable
influence on the subject’s system.
What is the temperature range of the sensors?
See “Specification” on pageD-1.
How is the accuracy of the thermometer sensors
guaranteed?
The accuracy of the sensors is established with a process traceable to the
Nation Bureau of Standards and Technology.
Can a glass bulb thermometer be used to check the
accuracy of my sensors?
No. Glass bulb thermometers are not accurate enough.
How can I check the accuracy of my Capsule Sensors?
You will need a highly temperature-stabilized water bath (better than
0.05 °C stability and accuracy), and a NIST traceable RTD digital
electronic thermometer.
Will the accuracy of the sensors degrade as their
batteries become low?
The sensors will remain accurate for up to 10 days of transmission.
How long will the sensors transmit?
Following activation, approximately 10 days (240 hours). This holds true
following a shelf life of up to one year.
After ingestion, when will the Capsule Sensor begin to
transmit actual core temperature?
Approximately one minute.
What is the best way to administer the Capsule Sensor?
Take it with a glass of water or a soft drink as you would most capsules or
pills.
