How do I install an insulin pen cartridge?
Insulin pens are commonly used in the treatment of diabetic patients, primarily for insulin injection. Insulin pens require specialized cartridges, which cannot be replaced at any time. During installation, the cartridge holder needs to be opened, a new cartridge installed, and tightened, completing the installation process of the insulin pen. The entire installation process is relatively simple and easy to understand.
Before changing the cartridge, it is essential to first determine its integrity and inspect the medication within the cartridge for any abnormalities. Check for cracks in the cartridge and ensure that the medication is normal. If no issues are found, the cartridge can be replaced.
To replace the cartridge, the original one needs to be removed by unscrewing the cartridge holder and taking out the empty cartridge. Rotate the base rod of the insulin pen's spiral in a clockwise direction, aligning the top and bottom of the spiral. Then, insert the new cartridge into the cartridge holder and tighten it clockwise. When injecting insulin, remove the protective cap.
Insulin cartridges should be replaced frequently, and the replacement time should not exceed three days. It is crucial to change the cartridge each time insulin is injected. Reusing cartridges can lead to injection pain, needle breakage, subcutaneous fat hyperplasia, hardness, and other adverse health effects.
When using an insulin pen, it is essential to observe the dosage changes of insulin. Generally, the cartridge holder of the insulin pen has a scale indicating the remaining insulin level. Injecting with sufficient insulin dosage ensures adequate insulin enters the body.
