insulin pumps

When do replace the parts

Teflon catheter Start by replacing it twice a week. If there are no problems try using it 4-5 days before replacement.
Metal needle Replace every threed day, more often if signs of irritation are noted.
Tubing Replace the tubing at least every other time you replace the needle/catheter and when you replace the reservoir.
Insulin reservoir Some pumps have prefilled reservoirs, other need to be filled. Do not reuse them as the silicon on the plunger wears off, resulting in "no delivery" alarms.
