Tegaderm Film to the Rescue
When I run out of the oval tape that comes with the Guardian 3 Sensors for the MiniMed 670G, the Tegaderm Film by 3M comes in very handy. I used these films for my Enlite sensor and the Medtronic MiniMd 530G.
The oval tape is a little complicated for me that I end up peeling the wrong side or get it all tangled up before applying it on my skin.
It seems as if I end up using an extra one during insertion and running out of the oval tape the tail end of my 3 moth supply.
The Tegaderm Film comes in different sizes and works well in covering the sensor and making it water proof just like the oval tape.
This summer I tested out two sizes bought at Amazon.
The larger size Tagaderm film (4”x43/4”)worked well for when I had to jump into the pool with the kids but it covers such a large area.
I liked the assurance that the sensor was completely waterproofed over a large area.
With the larger Tegaderm Film you certainly do not need apply extra tape under the Transmitter.
The smaller sized Tegaderm Film (2.375”x2.75) fits the same as the oval tape.
The only downside to the Tegaderm Film is that it will peel off if you do not apply it firmly to your skin.
The films can be pricey at local Pharmacies but you should get very reasonable prices (no more than $.50 per tape) on Amazon or Ebay.
