Insulin pumps, which deliver a continuous dose
of
insulin, are being used by more and more
diabetics, blind
and sighted, to achieve better diabetes control.
Unfortunately, there are health professionals
who assume it
isn't possible for a blind patient, or one with
severe
vision loss, to operate an insulin pump.� Too many health
professionals, and some blind people, have the
misconception
that blindness is synonymous with inability.
This article is intended to educate both the
health
care community and blind diabetics, to show them
that most
people with type 1 diabetes can successfully use
an insulin
pump if they desire.
Today's pump is about the size of a deck of
cards, and
is computerized.� Insulin runs from the pump, through a tube
(catheter or cannula) which is usually attached
to the
abdomen or thigh.� Insulin is delivered under the skin,
through the tiny, flexible tube.� The user programs the pump
for basal (continuous) delivery, small amounts
of short-
acting insulin 24 hours a day.� He/she also programs the
insulin pump for bolus insulin delivery, to
receive extra
insulin just before eating.� Insulin pumps have several
different controls and alarms, and your doctor
may want you
to spend a few days in the hospital for
training.
Insulin pump users need to check their blood
glucose at
least four times a day.� Since only short-acting insulin is
used, it is important the user check blood
sugars regularly
to avoid really high or low blood glucose.� Warning:�
If the
needle, or catheter, comes out from under the
skin, there is
no warning alarm to alert the user; and ketone
can start
building up in about one hour.� With little or no insulin in
the body, ketoacidosis can develop in just a few
hours.
Note:�
Pump users say the needle or cannula rarely, if ever,
comes out; and if it does, they can feel what
happened.
Additionally, if the needle has detached from
the skin, then
insulin will flow onto the clothing which will
after a while
become wet.�
Most users should also be cognizant of leaking
insulin, as it smells very bad.� To reiterate, it is
important that you closely monitor your blood
sugars.
An insulin pump might be what you need if you
are
having major problems controlling your blood
glucose with
insulin shots.�
You might consider a pump if insulin
injections do not keep your blood glucose near a
normal
level, or if you have big glucose swings.� Nighttime can be
difficult for some, because they have episodes
of
hypoglycemia, or get up in the morning with high
blood
sugars before breakfast.� The pump can be programmed, so it
can deliver less insulin at night and more
insulin before
dawn, minimizing nighttime lows and before
breakfast glucose
highs.�
We should all be monitoring our blood glucose,
working toward tight control.� We should all be working with
our health care team to reach euglycemia, normal
blood
glucose.
You may be able to wear your insulin pump while
bathing
or swimming.�
Some pumps are waterproof and some come with a
water protective case.
Insurance
Some insurance companies will help with the cost
of
pumps and supplies.� They realize better diabetes control
means less diabetes complications, less time in
the
hospital, and a bottom line of less expense for
the
insurance provider.� Your doctor should be able to help show
insurance companies the value of covering the
cost of pumps
and supplies.
As of April 1, 2000, Medicare began helping type
1
diabetics with the cost of pumps and related
supplies.� For

"Durable Medical Equipment."

They offer the H-tron Plus which costs $4,995,
and
comes with a second, backup pump (after 30
months, you send
the first pump back for servicing, and use the
backup).
Their much smaller pump, the Dahedi, about 2/3
the size and
weight, should cost about $5,000, and has
simple, two-button
programming (but no backup pump).� Disetronic says this pump
will be available in May.� Their newest insulin pump, the D-
Tron, scheduled for later this year, will offer
computer
interfacing, increased programmability,
vibration and audio
alarms, plus compatibility with insulin pen
cartridges (no
price data yet).� Supplies for any current pump, including
test strips, cost about $300 per month.� Disetronic does not
currently provide adaptive instructions on
audiocassette--
and when I asked them, they said they were
afraid of
"litigation."

They offer the MiniMed 508.� It costs $5,495.� Again,
supplies, including test strips, should cost
about $300 per
month.�
This pump allows remote control setting with a key-
ring sized "control unit," and a
"vibrating" mode can be
chosen, instead of the beep, for both settings
and alarms.
Minimed is currently working with our Diabetes
Action
Network to produce an audiocassette of
instructions for
blind pumpers.
The insulin pump is an amazing device.� If you have
type 1 diabetes, and need to use insulin, the
pump best
approximates the function of a healthy,
non-diabetic
pancreas.�
Can a blind diabetic use it, fill it, program it,
attach it, independently, without sighted
aid?� Absolutely.
As I said, there are still people who believe
otherwise, and some who just don't know.� Who are the
"experts" in this case?� The blind pumpers who are doing it
for themselves.�
Here's what they had to say about their
pumps:
Why should a blind diabetic consider the insulin
pump?
Susan Stewart, a blind pump user from Medina,
Ohio,
says:�
"I've always wanted to be on the pump; it was a
convenience thing.� The pump gives me more flexibility.� If
you're considering an insulin pump, definitely
really look
into it, because it has given me independence
and
freedom..."
Tammy Rupp, a blind pumper from Carrolton,
Georgia,
says:�
"The good thing about the pump is that you can be
real flexible.�
You don't have to be on a schedule.�
You can
be, but you don't have to be."
Sally York, a blind pumper from Castro Valley,
California, and Board Member of our National
Federation of
the Blind Diabetes Action Network, says:� "My MiniMed
insulin pump has given me back my
independence.� I can't
imagine going back to life on multiple
injections.� I can
honestly declare my pump has given my life a
positive
boost."
What specialized techniques do you use to
manipulate
the pump without sight?�
"With respect to filling the syringe,"
says Tom Tobin,
a blind pumper from Cleveland, Ohio, "I
have developed a
system that works well without any sighted
assistance.
First, when filling the syringe, I pull down on
the plunger
until the bottom of the syringe barrel and the
plunger are
about the distance from the tip of my index
finger to my
first knuckle; so as a measuring device, you
always have
your knuckle.
"Then, as with a regular syringe, I tap the
sides of
the syringe barrel and then push the insulin
back into the
vial.� I
repeat this step until I cannot hear any "bubbles"
escaping when pushing the insulin back into the
vial; there
should be a "smooth" sound.
"Next, since air may trap at the top of the
syringe
itself, I pull a little air into the syringe and
push up on
the plunger ever so slightly until insulin comes
out the tip
of the needle; just a little push.� That completes filling
the syringe.
"Next, while holding the syringe in my left
hand, I
take the infusion tubing and remove the cover at
the end of
the tubing that goes over the neck of the
syringe, where the
needle once was.� Make sure that there is a snug fit as you
tighten down the collar of the infusion set over
the neck of
the syringe.�
(I sometimes use my teeth to make sure it is
really tight.)�
Then I put the plunger of the syringe on a
flat surface, usually a table top, and begin
pushing down on
the barrel of the syringe, thus filling the
infusion set.� I
want to stress, that this should be done very,
very slowly
to avoid any pocketing of air in the
tubing.� If it is done
right, there should be no air bubbles at all in
the tubing.
Letting a drop fall on the back of your hand is
fine,
although I put the needle guard at the other end
of the
infusion set between my teeth, and use my tongue
to feel
when the drop falls.� Whatever works for you."
Tom Ley, from Baltimore, Maryland, a blind
pumper and
former president of our NFB Diabetes Action
Network, says:
"The process of filling the Mini Med 507 C
pump with a fresh
supply of insulin can be performed successfully
by a person
using non-visual techniques.� I will cover the subject of
inserting the cannula into the skin and securing
the cannula
with tape.�
Let me say, at the beginning, that not once in
my two years of experience has the cannula ever crimped
or
otherwise unsuccessfully seated itself under the
skin when
being implanted.� I also find this aspect of the process
very easy non-visually.
"It is much like giving a shot in many
ways.� Once the
needle is inserted into the skin, a piece of special
tape is
used to hold the cannula in place.� The tape is designed in
such a way that is extremely easy to position
correctly
without yet exposing the sticky side of the
tape.� Once the
tape is in place, three pieces of paper that
cover the
sticky part of the tape must be removed.� The pieces of
paper are pre- folded and shaped by the factory
to make
locating and removing extremely easy.
"Then, the final step is to remove the
needle from the
Teflon cannula.�
One simply must locate the large plastic
end of the needle protruding from the skin
through a hole in
the tape, twist it a quarter of a turn, and pull
out to
remove.�
It is possible that the cannula might crimp as it
is being inserted.� However, it is standard operating
procedure to check your blood sugar an hour
after changing
the pump set.�
If the sugar is abnormally high, then a set
of procedures should be followed to remedy the
situation.
This is no different than what a pump user does
any time
blood sugars seem unusually high.� As said earlier, in two
years, I have not yet experienced any problems
of this
nature when changing my pump set."
"One of the first things I learned was to
line up my
insulin bottle with the needle and syringe that
holds the
insulin in the pump," says blind pumper Donna
Blake, from
Waterbury, Connecticut.� "This may have not seemed like much
but at that time, I had never seen a
Count-A-Dose (tactile
insulin measuring device that enables blind
people to
accurately measure insulin without sight), nor
had I heard
about any alternative techniques for taking care
of insulin
and blood sugar needs.
"After I got the syringe filled, I devised
a simple way
to connect the syringe to the tubing aseptically
(in a
sterile manner).� I placed my thumbs together guiding the
hub of the syringe into the Leur lock of the
tubing.� I drew
the syringe back two fingers' width and this
gave me the
correct amount of insulin for three days.� Next, I realized
that I had bubbles that I did not know about, so
back I went
to step one.�
I found by pushing the insulin in and out of
the bottle several times (gently), I could
eliminate almost
all of the bubbles--most of the time, all of the
tiny
bubbles.
"In order to ensure that all of the air was
out of the
syringe, I would lightly tap the syringe on the
side of a
table to bring the bubbles to the top.� Then I took the
syringe, pulled a bit of air into it, reinserted
the needle
into the bottle of insulin and shot out the
air.� I then
tapped the needle on the side of the table and
pushed the
plunger until a few drops of insulin came out
(you can
really smell the insulin).� I connected the tubing and the
syringe.�
I held the syringe and the first few inches of
tubing upright and slowly depressed the plunger
so the
insulin filled the initial portion of the tubing
without
bubbles.�
I continued pushing insulin through the tubing
until I felt a drop fall out and hit the back of
my hand.
"I was almost ready to insert the
needle/catheter.� I
began this stage of the procedure after a shower
where I
scrubbed the site, where the catheter was
placed, thoroughly
with soap.�
I dried this area off with a clean towel,
separate from my other towels.� Next I prepared the site
with a liquid spray called "Sween
Prep," a protective skin
coating that keeps me from having an allergic
reaction to
the adhesive placed over the catheter site.� While this
stuff dried, I placed the syringe in the pump
and primed two
units of insulin through.� This step ensured that the
syringe inserted snugly within the pump and I
did not miss
any dose of insulin.�
"When my site was ready to receive the
catheter, I
inserted the needle just like anyone else with
diabetes does
giving an injection.� After I inserted the catheter, I
pulled out the small (25-gauge) needle and
placed a
protective tape over the catheter and now I
could go for
about three to four days."
What adaptive features are there to help you?
"It has a tone-activate button," says
Tammy Rupp.� "You
press it, and it has a tone, and you count the
tones for
each unit you need, to get your insulin
bolus.� Mine goes in
whole units; it can go in half-units, too.� And it will
automatically count it back to you so you can
check it.
"There's also a select button that you use
with the
activate button, to clear the pump's alarm, if
it goes off.
There's an alarm for "low battery,"
for if something's wrong
with the infusion set, or if the pump is out of
insulin.� It
beeps six times when you're out of insulin.��
Visually-impaired pumper Anne Whittington, MBA,
MSN,
RN, CDE, from Augusta, Georgia, says:� "Initially I was on
the MiniMed 504.� I found the buttons cumbersome (with my
rheumatoid arthritis) and the contrast poor on
the screen.
In 1993, I switched to the Disetronic pump.� The audible
alarms and crisp contrast met my needs
well."
Susan Stewart says:� "My insulin pump has a screen,
which I cannot read, that shows date and time,
and when the
alarm goes off, it tells what the alarm is
for.� It has four
buttons, and one of them is the
"select" button, with which
you select whatever screen you want.� I use it by counting.
Once I hit the activate button, it beeps.� And it has the up
and down arrows.� When I do a bolus before I eat, I push the
button.�
Say I want ten units; I'll push the button up;
it'll be 20 beeps.� Then I push the activate button again,
and it will replay the number of beeps, each 1/2
unit of
insulin, that I selected.� Another push on the activate
button, and it will start giving me the
insulin."
What about the cannula?� Does it bother you?� Is it safe?
Veronica Elsea, a blind pumper from Sylmar,
California,
says:�
"The insulin is delivered through a needle or
cannula, which is placed anywhere you'd give an
injection
with a syringe.�
I only use my abdomen; I find it easier and
more reliable.�
I use a Teflon cannula called "Tenders,"
made by Disetronic.� I find them easy to insert and very
forgiving.�
In fact, if you have any neuropathy in your
hands, you may actually find these cannulas and
cartridges
quite a blessing, as they're fatter and larger
than regular
syringes.�
The "Tenders" are inserted at an angle, anything
up to 45 degrees or so.� I just hold it at a slant, push it
in and don't worry about it!� As you might expect, once you
insert the cannula and remove its insertion needle,
it is
held in place with tape.� With the new "Tenders," the tape
is part of the cannula, so I no longer find
myself holding
something in place while searching for a piece
of tape
somewhere on a table!� It's designed for one-handed
operation by a sighted person, which means we
can do it
easily and comfortably with two.
"Only once, during an exuberant "good
morning," did my
guide dog reach up and catch her paw in the
tubing.� It's a
weird feeling when you catch the tubing on
something, but it
takes real effort to knock out the
cannula."
"I'm not afraid that the catheter would
fall out," says
Susan Stewart.�
"I use three pieces of medical tape holding
it in, and never in the months I've been using
it has it
come out, unless I mean to, when I'm taking it
off.� You
have to really tug on it sometimes to get it
off--the tape
is very sticky.�
Although there's no alarm that would sound
if it fell out, you would definitely know--you
would notice.
For one, my shirt would be soaked with the
insulin!
"Once you get used to wearing the cannula,
and to the
need to rotate it, you can tell if something's
wrong.� I can
tell if the tape's loose.� Usually on the third day, the
tape gets a little looser than the first or
second days,
since you've taken three showers since you
attached it.
"I can honestly say I feel practically no
discomfort at
all from the cannula that delivers my
insulin," says Tom
Ley.�
"I find its presence far more comfortable than taking
four insulin injections per day."
Do you have any advice for blind diabetics who
are
considering
the insulin pump?
"A lot of people say to me, 'Oh, I want the
pump and I
don't want to get injections anymore," says
blind pumper
Tricia Kline, from Doylestown, Ohio.� They think the pump is
the easy way out.� And I would say, unless you have the
commitment to continue, if you think all you
have to do is
get a pump and you can eat anything you want to,
that you
don't have to do this and that, and you don't
have to do
blood sugar testing, unless you are committed to
do that and
really work at it, you won't succeed with the
pump.� It's
not less work.�
Sure, some people think you throw out your
injecting needles and that, but it's still a big
commitment.
And unless you're willing to do that, and
willing to, and
have the confidence to do, your own adjustments,
you won't
succeed with the pump.� You have to develop, with your
doctor, a sliding scale; like if my blood sugar
is this
much, then I take this much insulin, or if it's
low I take
this much less.�
You get to know your body.� But
unless
you're willing to gain this much confidence in
yourself to
be able to make these changes on your own, you
will drive
your doctor crazy."
Anne Whittington says:� "Before selecting the company
with the best pump for you, consult your
diabetes management
team members.�
These team members go beyond your doctor, and
include your nurse dietitian, blind
rehabilitation
specialist, and whoever else may be assisting
you in
learning about the pump and its day-to-day
operation.� Also,
please speak with customer service
representatives from the
major companies before you select a pump.� Explain to them
your needs as a blind person.� Both Disetronic and MiniMed
have very helpful service personnel."
"With the MiniMed 507 pump at my
side," says Tom Ley,
"I'm eagerly beginning a new phase of my
life with diabetes.
After 25 years, I welcome days free from insulin
injections.
I'm excited about the prospect of fewer high and
low blood
sugar incidents, and I will enjoy my new
mealtime
flexibility immensely.� I'm comfortable, confident, and
content."
