2. Why we exist!
“To bring the experience of arterial line
placement to a new level of ease”

3. Our Competence
Affordable
Accurate
Easy to use
We protect patient’s privacy and provide a safety user enviroment

4. Data analysis—noise filter
High-pass filter at 800 Hz to
filter out low frequency noise

5. App design
● App records loudest volume
● Ratio =
CurrentVolume/LoudestVolume
● When Ratio=1 app is Red
● When Ratio=0 app is Blue
● When 0<Ratio<1, app is combination
of blue and red
● Touch the screen to reset
Doppler Ultrasound

6. Accuracy Test
n = 1
do 5 times
Mean = 1 mm from vessel
Standard deviation = 0.6 mm

7. Blind False/Positive Test
N = 16
Subjects’ Answers
Positive Negative
Location of radial
artery
Positive TP = 7 FP = 4
Negative FN = 0 TN = 5
Sensitivity = TP / (TP+ FN) 100%
Specificity = TN / (TN + FP) 55.7%

10. Projected Market
■ 5627 total hospitals in the U.S.
– If 15% buy at least 2 of our products, 844 hospitals* 2* $1000 = $1688000 revenue
■ Doctors without borders: 60 locations around the world
– If 35 of the centers in poor areas (e.g. Africa, Southern Asia) buy at least 4 of our
products, 35*4*$1000 = $140000 revenue
■ UNICEF: Currently working in 37 countries
– If 25 locations in the developing worlds purchase at least 3 of our products, 25*3*$1000 =
$75000 revenue
■ 100 Percent Market Penetration = $11605000 revenue
■ Projected Cumulative Third Year Market Penetration = $1903000 revenue = (16.4% market
penetration)

13. Question?

14. Persona
Susan:
Susan was a victim of an earthquake. Her right
leg got stabbed through by two steel rods and
she was bleeding a lot. A nurse quickly
placed a cannula into Susan’s radial artery
by using Vascular Locator app with a
doppler ultrasound device. This saved
Susan because Doctors Without Borders
could monitor blood pressure and started to
perform operation right the way
Nurse Thomson:
Nurse Thomson is working at Quest
Diagnostics. He requires to withdraw
blood from radial artery ten times a day
for measuring pH . He doesn’t miss place
the needle because he uses Vascular
Locator app with a doppler ultrasound
device. His patients are highly
satisfactory.

15. - 9.1 MHz Doppler Ultrasound system connected to an Android App that locates radial artery
- Location of radial artery and applied to the clinical Arterial Line Placement.

16. Problem
- Nepal earthquake (2015) - 40000 injuries vs. 10 hospitals in the Kathmandu
Valley
- Ultrasound guided radial line insertion:
+ Invasive blood pressure measurement (gold standard) required for surgical
operation
+ Avoid nerve injury
Reduce pain when
perform arterial line
Difficult to straighten
wrist; weak fingers
Limited

17. Experiment Set-up
Arduino based
Servo to mimic the
heart pulse
Big one for collect the data & smaller
two are designed for the accuracy
tests.Syringe pump to generate
the input flow at the rate of
40ml/min.
