2. INTRODUCTIONINTRODUCTION
People with diabetes cannot make their own
insulin, a hormone that is normally secreted by
the pancreas. Insulin is essential to metabolise
sugar and hence generate energy.
Currently most diabetics inject insulin 2 or more
times per day, with the dose injected based on
readings of their blood sugar level.

3. INSULIN PUMP
A personal insulin pump is an external
device that mimics the function of the
pancreas.
It uses an embedded sensor to measure
blood sugar level at periodic intervals and
 then injects insulin to maintain the blood
sugar at a ‘normal’ level.
Also known as Continuous Subcutaneous
Infusion Therapy.

4. The device configuration may vary
depending on design.
The traditional pump includes:
 The pump (controls, processing modules
& batteries).
A disposable reservoir for insulin (inside
the pump).
A disposable infusion set, including a
canula for subcutaneous insertion (under
the skin) & a tubing system to interface
the insulin reservoir to the canula.

How to use an insulin pump
•Filling reservoir with insulin.
•Once reservoir is filled remove the
plunger.
•Attached to the infusion set.
•Put the new infusion set into the pump.
•Prime the pump by pushing a few
command button on your pump.
(priming means fill the cord with insulin.
During priming insulin come out of the
needle end of infusion set.)

9. 9
•Once it is primed ,set the needle end of
the infusion set in to the Quick-serter.
•Sterilize the area planning to place the
set.
•Quick-serter loads the set into the place
with the push of a button.
•Remove the Quick-serter.

4.Infusion set Insertion device
Insulin pump:
A small durable medical device that
has,
◘Buttons to program your insulin.
◘LCD screen to show what you are
programming.

15. 15
◘Battery compartment to hold 1 AAA
alkaline battery.
◘Reservoir compartment that holds
insulin.
•Reservoir:
A plastic cartridge that holds the insulin
that is locked in to the insulin pump.
It comes with a transfer guard that
assist with pulling the insulin from vial
in to the reservoir.
A reservoir can hold up to 300 units of
insulin & is charged every 2-3 days.

16. 16
•Infusion set:
An infusion set includes a thin tube that
goes from the reservoir to the infusion
site on your body.
The canula is inserted with a small
needle that is removed after it is in
place.
It goes in to the sites on your body
similar to where you give your insulin
injection.
The infusion set is changed every 2-3
days.

17. 17
•Infusion set insertion device:
An infusion set is placed in to the
insertion device & with a push of a
button , the infusion set is inserted
quickly & easily.

18. 18
Dosing of insulin:
•The insulin pump delivers a single type of
rapid acting insulin in 2 ways.
a.A bolus dose: That is pumped to cover food
eaten or to correct a high blood glucose level.
b.A basal dose: That is pumped continuously
at adjustable basal rate to deliver insulin
needed between meals & at night.

19. CHARACTERISTICS OF AN
IDEAL INSULIN PUMP
Deliver drug with in prescribed rates for
extended periods (2-5 yrs).
Accuracy & precision.
Reliable.
Chemically, physically & biologically
stable.
Compatible with drugs.
Non-antigenic & non-carcinogenic.
Must have over dose protection.
Convenient to use.
19

20. 20
•Implantable by local anesthesia.
•Able to monitor the performance of the
pump.
•Must be sterilizable.
• Have wide delivery rate for basal &
bolus deliveries to meet patient
variability.
•Long reservoir & battery life & easy
programmability.
