Motorola鈥檚 MPX2300D Pressure Sensors.
Motorola鈥檚
MPX2300D pressure sensor has been designed for medical
usage by combining the performance of Motorola鈥檚 shear
stress pressure sensor design and the use of biomedically
approved materials. Materials with a proven history in
medical situations have been chosen to provide a sensor
that can be used with confidence in applications, such as
invasive blood pressure monitoring. It can be sterilized using
ethylene oxide. The portions of the pressure sensor that are
required to be biomedically approved are the rigid housing
and the gel coating.
The rigid housing is molded from a white, medical grade
polysulfone that has passed extensive biological testing
including: tissue culture test, rabbit implant, hemolysis,
intracutaneous test in rabbits, and system toxicity, USP.
A silicone dielectric gel that has been used extensively in
implants covers the silicon piezoresistive sensing element.
The gel is a nontoxic, nonallergenic polymer system which
passes pyrogen testing, as well as meeting all USP XX Bio-
logical Testing Class VI requirements. The properties of the
gel allow it to transmit pressure uniformly to the diaphragm
surface, while isolating the internal electrical connections
from the corrosive effects of fluids, such as saline solution.
The gel provides electrical isolation sufficient to withstand
defibrillation testing, as specified in the proposed Association
for the Advancement of Medical Instrumentation (AAMI)
Standard for blood pressure transducers. A biomedically ap-
proved opaque filler in the gel prevents bright operating room
lights from affecting the performance of the sensor.
