No. The Accu-Chek LinkAssist insertion device is exclusively for use on one person. It must not be used on several people.

Health care professionals and Diabetes Nurse Educators are a valuable source of information and training for all people with diabetes, which you should take advantage of regularly. It is not necessary, however, to get professional instruction before using Accu-Chek LinkAssist for the first time. Just follow the instructions for use contained in the packaging.

No, this is not necessary. 

The elongated perforation mark on the self-adhesive backing directs you to the location of the tube connection.

Do not store the Accu-Chek LinkAssist device pre-tensioned. The tensioning element should be completely outside of the base. Avoid storing the insertion device in extreme temperatures, such as a hot car in the summer.

If needed, wipe the outside of the Accu-Chek LinkAssist insertion device with a cloth moistened beforehand with water, a mild hand soap or a standard disinfectant (e.g. 70% ethyl alcohol). Do not dip the insertion device into the cleaning fluid. Dry the insertion device thoroughly with a soft, clean cloth.

Please wash your hands before use. Choose a site away from waistline, bones, scar tissue, belly button and recent insertion sites. Prepare site according to the instructions from your health care professional. Allow the insertion site to dry before the cannula is inserted.


  1. Push the tensioning element (grey) of the insertion device into its base (blue).
  2. The insertion device is now pre-tensioned. This step “locks” the safety catch in place, and automatically makes the insertion device secure.
  3. Hold the infusion set by its protective cover between the thumb and the forefinger and with the blue holder cap pointing upward, insert it from below into the opening of the insertion device until you feel it lock into place.
  4. Carefully remove the transparent protective cover of the infusion set by turning and pulling at the same time.
  5. Remove both pieces of the self-adhesive backing from the infusion set.
  6. Hold the base of the insertion device firmly in one hand and with the other hand pull the tensioning element (grey) out and up as far as it will go.
  7. Holding the tensioning element, position the insertion device onto the prepared infusion site. Activate the insertion device by sliding the safety catch out of the “lock” position. Press the release button to introduce the cannula into the skin. The Accu-Chek LinkAssist insertion device can now be removed from the infusion site and set aside.
  8. Smooth out the self-adhesive and run your fingers over it. This ensures good skin contact and secure positioning of the infusion set.
  9. Hold the self-adhesive in place. Carefully and gently press the side clips of the blue holder cap together and pull it from the cannula housing.
  10. To remove the introducer needle, hold the cannula housing firmly to your body. Withdraw the introducer needle by its blue handle in a straight angle. Discard your introducer needle and infusion set after use according to local regulations.
  11. Connect the primed* tubing to the newly inserted cannula. A click must be heard when connecting. Fill the empty space of the cannula with a bolus of 1.0 units of insulin U-100.  Start the insulin pump.


*How to prime the tubing set: Screw the luer-lock tightly into the insulin pump adapter. Prime the Accu-Chek FlexLink infusion set according to the insulin pump manufacturer’s operating instructions until the insulin emerges at the tip of the connector needle. Do not leave air bubbles in either the cartridge or the tubing.
