1. Avoid pain, reduce the resistance of diabetic patients such as needle phobia, make them more willing to cooperate with the treatment, and greatly improve the treatment compliance;
2. It does not break the needle and does not puncture the skin, which ensures aseptic operation to a greater extent and reduces the risk of infection;
3. Needle free injection is distributed dispersedly after entering the subcutaneous in the form of spray, which makes the contact area of the liquid medicine larger, the absorption more efficient and uniform, and the blood sugar control effect better;
4. Does not cause subcutaneous induration due to repeated injections
Disadvantages: Compared to insulin injection pens, they are more expensive and bulkier, making them less convenient to carry.
Therefore, regardless of which option to choose, it is necessary to consider it clearly based on your own actual situation.
1. The operation is simple, and diabetes patients can quickly master the use skills under the guidance of medical staff, which is easy to learn and master. It is relatively compact and convenient to travel and carry, and can also hide the injection process to avoid embarrassment;
2. The needle is small, generally 4-5mm, which can alleviate injection pain;
3. Avoid diabetes ketoacidosis due to equipment problems
4. Low cost
1. The insulin pen should inject at least 0.5 unit of insulin, which cannot achieve micro injection;
2. Needles need to be changed once. If the needles are not changed or injected in one place for a long time, it can easily lead to subcutaneous induration, which can affect insulin absorption and maintain blood sugar stability;
3. Long term needle insertion can damage skin tissue, causing needle eye and pain
4. Needle fearing and needle fainting diabetes patients will have a great psychological burden, and improper operation will easily cause needle breakage, infection, etc
