Medtronic recently recalled more than 322,000 MiniMed insulin pumps with broken or missing retainer rings that led to at least one death, thousands of injuries, and numerous lawsuits. The recall arose after broken or missing retainer rings were observed on the devices. The ring defect that could prevent the insulin cartridge from being locked into place and, as a result, cause people to receive too much or too little insulin.
Insulin overdose can lead to hypoglycemia, a condition in which the blood sugar is lower than normal, leading to lethargy and insulin shock. Underdosage may cause hyperglycemia, which occurs when there are high levels of sugar (glucose) in the blood. Hyperglycemia can lead to a severe condition known as diabetic ketoacidosis (DKA). Without treatment, someone with DKA is in danger of falling into a diabetic coma.
