TheRequirement
SolutionProvided
The customer is a technology leader providing highly-integrated signal
acquisition and signal processing data management products for
electrophysiologicalmedicaldevices.
Therequirementwastodesignamedicaldeviceforfetal-maternalmonitoring
and also to develop an application to display the processed data on a tablet or
aPC.
Mistral was involved in developing the hardware solution, integrating
the signal processing algorithms into the framework, and the host GUI
application.
The medical device developed for this application consisted of the following
hardwaremodules:
Analog Interface card supporting 32-channel of analog input data (human
electrophysiologicaldatacollectedthroughelectrodes)
DSPbasedBio-MedicalBoard
Programmable Control Module comprising of OMAPL138 and the CPLD for
theanalogcardinterface.
The device is designed to function in two variants; one with data processing
beingdonebytheDSPbasedBio-MedicalBoardandanothervariantwithdata
processingbeingdoneontheControlModule.
The device processes the raw analog input, converts it to digital data and
applies ECG algorithms for extracting maternal and fetal data and metrics
such as ECG, maternal and fetal heart rates and ST analysis. The device
interfaces with the host PC via USB. The host GUI application receives the
processed data from the device and presents it in a graphical format while
providingpatientalarmsandelectronicpatientrecords.
The GUI application is designed to work in a normal Windows 7 host PC, as
well as touch-based handheld versions of the OS. The generic framework
provided by the application enables it to be seamlessly used on an Intel i7-
basedWindows7tabletcomputer.

Introduction
This case study showcases Mistral's expertise in providing product
design services in the non-invasive medical electronics segment.
Mistral was approached by a leading original device manufacturer
(ODM) in the US specializing in design and development of products
related to patient monitoring. Mistral's concept-to-deployment
services helped in realizing the customer's idea for fetal-maternal
monitoringdevice,andhelpbringitquickly-to-market.

The application, especially the graphical representation, had to be
designed to work smoothly in touch-based environments, including
touch-basedrewindfunctionalities
Real-time data being received by the analog interface card had to be
processed and displayed without any data loss. Microseconds of data
lost would be interpreted by the algorithm as an error or dip in the
patient's vital signs. In the process, even a healthy person could be
reportedasunhealthy.
