One is the common type of insulin, which is a needle-type insulin syringe, which is specially used to extract this common insulin. The scale on the syringe is relatively accurate. Because it needs to extract insulin according to 0.1 ml or a finer scale, its scale is relatively small, and the needle tube is thinner. Now this is still used more in our clinical work. Yes, especially when clinical treatment with regular insulin is required.
In addition, the most common and most convenient way for diabetic patients to inject insulin by themselves is an insulin injection pen. This insulin injection pen is indeed much more convenient to use than a needle-type syringe, and the insulin injection pen can be carried around.
Then, before each injection, we only need to install a sterile insulin needle. The injection needle can be injected after adjusting the scale accurately, so it is relatively convenient, and it is also the most widely used tool for insulin injection.
