The usage method and precautions for insulin pens are as follows:
1. The insulin pen in use must be paired with a cartridge, and if not paired, it cannot be installed. The insulin pens produced by each manufacturer can only be matched with our own cartridge bottles, otherwise they cannot be used normally.
2. When using an insulin pen for injection for the first time, after installing the needle, it is necessary to exhaust and adjust the two units of insulin to be pushed out.
3. Insulin pens should not be exposed to sunlight, and should not be placed in low temperature areas to prevent insulin deterioration and failure. They can be stored in refrigerated areas.
4. When not in use for a long time, the insulin pen should be kept in a cool and ventilated place for maintenance.
5. During the use of insulin pens, attention should be paid to cleanliness and hygiene. If any liquid drips out after use, it should be wiped clean.
