 Insulin Pumps

An insulin pump is a small, battery-operated device that supplies a continuous amount of insulin to the body. You should talk with your healthcare team before purchasing and using a pump.

Some things to know about insulin pumps:

• The pump contains a battery, a motor and a supply of insulin.
  
• The pump is connected to the body by tubing and a single needle or soft cannula. The insertion site is rotated every 1 to 3 days.
  
• Insulin that is delivered continuously is called the basal dose. The dose given before meals is called a bolus dose.
  
• Eliminates need for multiple injections to implement intensified therapy.
  
• Allows for better blood glucose control.
  
• Works continuously, similar to a healthy pancreas.
  
• Makes it easier to adjust doses.
  
• Most insurance companies cover pumps.
  
• DKA may develop rapidly, if pump fails, tubing crimps, or needle pulls out.
  
• The decision to use an insulin pump requires careful consultation with your diabetes care team.

Pump Users Must:

• Be under the supervision of a doctor who understands the technicalities of the insulin pump.
  
• Check blood glucose levels frequently.
  
• Be able to cover its costs.
