Maintaining precise blood glucose control requires that all components of your infusion system function perfectly. It’s not just about logistics, but an essential safety measure to prevent hyperglycemia and ensure insulin is properly absorbed into the subcutaneous tissue.
Because this equipment is vital for your health and costly, at Glucody we recommend protecting it against accidental impacts. That’s why we offer various insulin pump accessories that ensure the safety of your device while it works to keep your levels stable.
Replacement frequency: How often should the catheter and reservoir be changed?
The component that requires the most attention is the infusion set (catheter and cannula) along with the insulin reservoir. According to technical standards, these elements should be changed every 2 to 3 days, which equals a range of 48 to 72 hours.
Keeping these components beyond the recommended time can seriously affect treatment:
-
Loss of accuracy: The risk of insulin crystal or lump formation, known as lipohypertrophy, increases, which affects dose accuracy.
-
Risk of infection: Regularly changing the cannula is essential to avoid infections at the insertion site.
-
Flow blockages: Replacing the reservoir prevents obstructions that could interrupt insulin delivery.
Insertion site rotation
As important as the usage time is the device location. It is crucial to change the insertion site with each equipment replacement. This practice allows the skin to properly recover and ensures insulin is absorbed effectively to maintain glucose control.
Lifespan of an insulin pump
The lifespan of the main device depends on its internal technology and hardware wear. Insurers and manufacturers usually cover a new pump every 4 years. This period is set to ensure the patient always has a guaranteed device that works reliably.
On the other hand, if you use an integrated continuous glucose monitor, remember that the CGM transmitter has a shorter lifespan and usually requires replacement every year.
| Component | Recommended replacement frequency | Main reason |
| Infusion set | Every 48 - 72 hours | Prevent infections and ensure absorption. |
| Reservoir | Every 48 - 72 hours | Avoid blockages and loss of accuracy. |
| CGM transmitter | Every 1 year | Technical battery depletion. |
| Device (Pump) | Every 4 years | Replacement due to end of technical warranty. |
How to know when it’s necessary to change the insulin pump?
There are warning signs indicating that the infusion set must be changed immediately, even if 72 hours have not passed. You should watch for signs of irritation in the area or bleeding at the insertion point.
Another critical sign is noticing ineffective insulin delivery. If you observe unusually high glucose levels that don’t drop after a correction bolus, the cannula is likely blocked or bent, requiring urgent replacement of the catheter and reservoir.
Take care of your insulin pump with Glucody
Wearing an infusion system 24 hours a day exposes your technology to rubbing against furniture or accidental drops. Since the main device should accompany you for at least 4 years, its physical protection is an absolute priority to avoid premature technical failures.
At Glucody, we specialize in designing solutions that combine safety and style. By using our insulin pump accessories, such as ergonomic protective covers, you add a resistant barrier that absorbs impacts and protects your device’s screen from scratches.
