The insulin pen injection needle cannot be reused. For the sake of health, please do not reuse the insulin pen needle.
In addition, before discarding the insulin pen needle, the needle should be capped or placed in a covered hard plastic or metal container, marked as "non-recyclable", so as to prevent sharp tools from being mixed with domestic garbage and increase the risk of stabbing and infection of others.
Extended information:
The hazards of repeated use of the insulin pen needle include:
Broken needle
In order to relieve the pain during injection, the insulin pen needle is very thin and is produced according to the disposable standard. Repeated use will easily lead to the needle breaking in the body, and the broken needle will wander in the body, making it difficult to take out, threatening the health of patients.
needle blockage
there will be residual insulin crystals in the needle tube of the used needle, and repeated use will block the needle and affect the next injection.
injection pain
under the microscope, we can clearly observe that repeated use will cause burrs, bends and barbs on the needle tip, which will lead to bleeding and abrasions at the injection site and aggravate the pain.
Hyperplasia or induration of subcutaneous tissue
Repeated use of deformed needles will cause micro-trauma of subcutaneous tissue, which will lead to subcutaneous fat induration for a long time. Sclerosis will lead to the decrease of insulin absorption rate, the extension of absorption time, and the difficulty of controlling blood sugar will also increase.
Injection site infection
After repeated use, bacteria in the air and on the needle tip can enter the refill through the needle tube, which not only pollutes the liquid medicine, but also increases the risk of local infection.
Affect the concentration and injection dosage of insulin
If the needle is not removed after injection, when the patient takes the injection pen from a cool place to a warm place (such as going out in summer or entering a heated building in winter), the insulin in the refill will expand and overflow from the needle, resulting in a change in the concentration of mixed insulin.
On the contrary, when the patient takes the injection pen from a warm place to a cool place, the volume contraction of insulin causes air to enter the refill to generate bubbles, which prolongs the injection time, which may lead to leakage after injection and affect the accuracy of injection dosage.
