1. Can't push the insulin injection button
Reason 1: The needle is clogged or the inner needle of the needle has not pierced the rubber membrane of the insulin cartridge;
Reason 2: Running out of insulin in the refill;
Countermeasure: After correctly replacing the insulin needle, if the injection button is still not pressed, you need to check if the medication in the refill has been used up.
2. Repeated venting with no insulin dripping from the tip of the needle
Reason 1: The unterminated end of the insulin pen piston rod is tight against the rubber piston at the end of the refill;
Reason 2: Air enters the quill and the exhaust dose is insufficient;
Reason 3: Rotating the insulin pen injection button while venting or injecting insulin;
Countermeasures: First, when insulin is not injected, it is best not to dismantle the quill holder to prevent the screw from recovering and then filling with used insulin, and the regular dose of exhaust can not be discharged normally insulin;
Second, insulin is not stored properly, due to thermal expansion and contraction, air will enter into the quill, resulting in the regular dose of exhaust can not be properly discharged insulin;
Third, whether injecting insulin or venting, press the injection button, not rotate it.
The above situations are a few common situations in which insulin injections for sugar users are “malfunctioning” due to improper operation, and we hope that you will try to avoid the above problems in the process of using insulin pens. If you can't solve the problem by yourself, we recommend you to seek guidance from a professional diabetes educator.
