Insulin pen refill matching

At present, the insulin pens in the domestic market include Novo Pen (Novo Nordisk, Denmark), Youban Pen (Lilly of the United States), Automatic Pen (Omanford, UK), Tex Pen (Aventis, France), East Baobi (China Tonghua Dongbao Company). Patients need to know which manufacturer's insulin pens they are using, and they must use the insulin pen cores from that manufacturer. For example: Novo pens can only use various types of refills produced by Novo Nordisk, Youban pens can only use various types of refills produced by Eli Lilly, and Tex pens can only use those produced by Aventis. Long-acting basal insulin comes at the right time.

Prepare insulin refills, needles, insulin pens, 75% medical alcohol, and medical cotton swabs before injection.

Insulin pen check and installation

Before installation, you should carefully check whether the refill is intact and there are no cracks; if there is any abnormality in the color and properties of the liquid in the refill, whether there are floc or crystal precipitation; whether the refill has expired. After confirming that it is correct, twist the refill holder, insert the refill, sterilize the rubber film on the front of the refill with 75% alcohol, remove the needle, open the package, and tighten the needle clockwise to complete the installation. Just remove the needle protective cap during the injection.

Insulin pen vent

The newly replaced refill, because the drive rod and the end of the refill are not close enough, if the injection is not exhausted, the injected dose will be 4-6 units less. Put the pen upright so that the air bubbles in the pen core gather on the upper part, turn the dose adjustment knob to "2 units", and then press the injection button to reset it to zero. If a drop of insulin overflows from the needle, it means the drive rod It has made full contact with the refill and the air bubbles in the refill have been completely discharged. If no liquid is discharged, repeat this operation until a drop of insulin is discharged. Note: Do this every time you install a new refill and needle.

Insulin pen injection method

Before each injection, check that there is a sufficient dose of insulin, and then turn the dose adjustment knob to the number of injection units required. If the injected insulin is a suspension (such as medium-acting insulin or pre-mixed insulin), the insulin pen should be turned upside down about 10 times until the solution becomes a uniform white suspension, in order to prevent the uneven concentration of the solution Poor blood sugar control. Fast-acting insulins (such as Nuo Rui), short-acting insulins (such as Nuo He Ling R), and insulin glargine (when available) are clear solutions that can be injected directly.

Specific injection method: conventional disinfection of the injection site, pick up the skin of the injection site with your left hand, quickly insert the needle at a 45-degree angle (thin person) or vertical (fat person) with the right hand, and press the injection button on the right thumb to slowly and uniformly inject the liquid. After the injection is completed, the needle stays under the skin for 6 seconds, and then the needle is quickly pulled out in the direction of needle insertion, and the eye of the needle is pressed with a dry cotton swab for 30 seconds. Close the needle cap and finish the injection.
