Remind! Don't use the injection needle for the second time
Speaking of standardized injection, we must eliminate the repeated use of injection needles.
"Many patients reuse needles for saving or other reasons. In fact, this practice is very harmful and will only increase costs in the end." After the injection needle is reused, the residual liquid in the needle will affect the accuracy of the injection dose. The residual insulin in the used needle will form crystals, which will block the needle and hinder the injection. In addition, the needle left on the insulin pen after injection will lead to inaccurate insulin injection dose due to thermal expansion and contraction.
Studies have shown that repeated use of the injection needle will cause the needle tip passivation, the lubricating layer on the surface of the needle will fall off, increase the pain of patients, and directly affect the compliance of patients. With the increase of the number of repeated use of needles, the proportion of patients with poor blood glucose control also increased significantly. Repeated use of needles leads to subcutaneous fat hyperplasia, large fluctuations in blood glucose, difficult blood glucose to meet the standard, increased insulin consumption, and finally increased the treatment cost.
Therefore, it is very necessary to use the injection needle only once, not only for health itself, but also for reducing the treatment cost.

Avoid the following situations
"Insulin injection is generally safe and painless, but there may be some problems due to improper operation or individual differences. At this time, it is necessary to consult a doctor in time and solve the problems in time."
For example, insulin injection is painless in most cases, unless the needle directly touches the nerve endings, but this is not common. However, some patients may feel pain due to abnormal sensitivity.
Methods to reduce injection pain include storing insulin in use at room temperature; If alcohol is used to disinfect the injection site, it should be injected after the alcohol is completely volatilized; Avoid injecting at the root of body hair; Choose a needle with small diameter and short length; Use a new needle for each injection. If you don't know the cause of the pain, consult a doctor.
In addition, the injection needle sometimes touches the blood vessels, resulting in local bleeding or congestion. Changing the length of the injection needle or changing other injection parameters is not easy to change the probability of bleeding or congestion. In addition, long-term injection may lead to local infection, local redness, induration, ulceration, etc. These situations need to be avoided by contacting the doctor in time and appropriately changing the injection site.

Three elements of injection site standard inspection
Due to the increasing number of patients with diabetes in China, now hospitals have a series of norms on insulin injection. For example, as for the injection site, if patients can do the following three points, they will avoid most risks.
1. Select the corresponding injection site according to the type of insulin used.
Recommended method: when using short acting insulin or short acting and medium acting insulin, the priority injection site is the abdomen. For medium and long-acting insulin, such as the medium-acting insulin injected before going to bed, the most suitable injection site is the hip or thigh.
2. Regularly check the injection site.
Recommended method: check the injection site before each injection, judge and avoid the parts with pain, skin depression, skin induration, bleeding, ecchymosis and infection. If skin induration is found, please confirm the location and size of the induration, and avoid induration for injection.
3. Rotate the injection site regularly.
Recommended method: inject the same part at the same time every day (for example, the doctor recommends that you inject the abdomen every morning, so you should always choose to inject the abdomen in the morning, and do not change to other parts at will). Rotate the injection site around every week (for example, thigh injection can be injected on the left and right for one week). Each injection point should be at least 1 cm away from the last injection point. Avoid reusing the same injection point within 1 month.
The above is how to regulate the precautions of insulin injection. If you need to consult the insulin injection pen, please contact Wanhai medical, professional research and development, production of insulin injection pen, manufacturer direct sales, quality assurance!
