Contact sport and sensor protection

Football, hockey, basketball, rugby and martial arts are full of knocks, grabs and falls. Devices can survive a lot, but sensors get ripped off, and pods and sets get knocked loose. This guide explains what protective gear can and can't do. How to manage insulin and glucose during sport is a conversation for your care team.

What hard shells do

Rigid covers and shells spread a knock over a wider area and stop the edge of a device from catching on a jersey, a pad or another player. They're good at preventing snags and glancing blows.

What they don't do

A shell isn't armor. A direct, hard impact, like a knee or a helmet, can still hurt and can still dislodge a sensor underneath. A shell that presses down on a sensor can also cause discomfort and may affect readings. Choose covers that sit around a device without pressing on it, and check your device maker's guidance on covers.

Placement is the first protection

Put devices where hits are least likely. For many sports that means avoiding the outer thigh, the upper arm on the side you tackle or block with, and anywhere under shoulder or hip pads that might rub. Talk with your coach about which areas see the most contact. Use only sites your system is approved for.

Securing everything

An overpatch with a strong acrylic adhesive under a soft or rigid cover is a common combination. Compression shorts or sleeves over the top add another layer and hold everything flat. For tubed pumps, decisions about disconnecting or suspending during play belong with your care team. If you do wear one, a snug sports pouch and taped tubing prevent pulls.

On the sideline

Keep a low-treatment kit, spare sensor or set, overpatches, and adhesive wipes in the team bag. Make sure a coach or teammate knows what a low looks like and where your kit and any glucagon are. Many sports have rules on what can be worn during play, so check with officials if needed.
