Slide1

Monitoring Blood Glucose Concentration Levels for Diabetes Using LabView

Diane Kim

Final Presentation

Knoxville, TennesseeSlide2

Diabetes

Lack of insulin produced in one’s pancreas, or the insulin is incompatible with one’s body

Insulin serves as a “key”

When you eat, your body turns food into glucoseAt this point, your pancreas releases insulinOpens cells and allows glucose to enter, which provides energy Patients must manage their glucose levels carefully

2Slide3

Causes and SymptomsType 1 and Type 2 are predominant, though Gestational and other types do exist

Type 1 makes up only 5% of the diabetes population

Type 2 is mainly caused by diet or environmental influences

Symptoms include:Extreme thirst or hungerSweet smelling breathKetoacidosis (diabetic coma)Slide4

Today’s MethodsMethods today include finger pricking or urine testing, though finger pricking is more accurate

Europe has a noninvasive measurement device that clips onto one’s earlobe (

GlucoTrack

)Slide5

iBGStar MonitorConnects to an

iPhone

or iPod touch device

Comes with test strips that the patient would apply their blood to, and run the test strip through the deviceSlide6

CGM SensorsA minuscule electrode is inserted under the skin, which measures glucose levels in tissue fluid

Connected to a transmitter that sends information to the device via a wireless radio frequencySlide7

DisadvantagesFinger pricking, while accurate, is painful and difficult for those with physical limitations

Also leads to sensitive and calloused fingertip

An inconvenience to have to do every day for life

Placing sensors under the skin can lead to health hazardsCell rejectionBatteries can leak acid into bloodstream, potentially killing the patientSlide8

Designing a program for sensorsGoal: Provide cheaper sensors while still maintaining accuracy

LabView

: visual programming platform

Process:Receive signal Read and analyze given dataCalculate slopeUse slope and frequencies from signal to calculate unknown blood glucose concentrationsSlide9

LabView Program

Program will allow a wireless chip to monitor glucose levels

Uses correlation between frequencies and blood glucose levels

When levels are dangerously low or high, it gives an alert (LED Signal) Current process includes a signal simulation, use of slope formula, read to text capability

AdvantagesAntiquate finger pricking methods

Allow utmost accuracy by calculating each individual pair of correlations rather than calculating a line of best fit

Save costs (no need for strips or monitors that need to be updated)Slide19
