Thermal flow sensors could provide a low-cost solution to common problems in hemodialysis machines like faults in pressure sensors, air detectors, blood pumps, and heaters. Using thermal flow sensors instead of pressure sensors and heaters could create a safer machine that reduces blood coagulation inside tubes by maintaining blood temperature. Embedded CBC and pulse oximetry monitors add costs, so thermal flow sensors may be the best development option to achieve an affordable, multi-functional hemodialysis machine with long-term sensors. Precise temperature control of any heaters would need to be considered to avoid exceeding normal blood temperature of 37C.

3. Problem of
hemodialysis machine
01
Common problems maybe happen
In hemodialysis machine :
1-fault in pressure ,ultrasonic air
detector sensors
2-fault blood pump or heparin
pump
3-fault heater
4-fault dialyzer

4. Need & motivation for development
High effective machine Long term sensors Multifunction product
Provide machine with
monitoring heart beats
Embeded cbc with
hemodialysis machine
Use robotic arm for pull
And return blood to
patient

5. Thermal flow sensor solution fault
pressure sensor and heater
Embedded CBC in hemodialysis
machine solution multifunction need
Necessary elements in solution
Make pulse oximeter to monitor heart
beats solution monitor need
Use robotic arm for pull And return
blood to patient solution effect of delta
adapter

6. Create hemodialysis machine
with long term sensors and
reduce costs "market need” by
using thermal flow sensor
instead of pressure sensor and
heater .this make device more
safety for coagulation blood
inside tubes “improve function “
because blood lose heat when
pass through tubes
Opportunity statement

7. Frustrations and
complaints
 Embedded CBC in hemodialysis machine make
cost high.
 Make pulse oximeter to monitor heart beats is
we can make it additional solution or optional.
 Use robotic arm for pull And return blood to
patient high cost.
 Thermal flow sensor solution fault pressure
sensor and heater best development to achieve
low cost.

8. Inefficiencies and scan resources
Maybe happen some
problem when we use
thermal flow meter if
heater produce
temperature higher from
37C˚ “blood temperature”
So ,we must make heater
not exceeds this value .
Resources of thermal flow
meter :
 This sensor contain from
two temperature sensor
 One heater
“Considers low cost and
easy to fitting”
