Help reduce pain and burden for people with diabetes.
At present, many diabetic patients in the world need to rely on insulin injection to control blood sugar, so the correct injection of insulin is particularly important at this time, if the operation is not standardized, it may lead to injection pain, bleeding, leakage, nodules and other adverse effects. Therefore, the next correct injection of insulin "dry goods" must be collected!
First, you need to get these points before you give the injection
1. Understand the common device for injecting insulin: insulin pen
2. Wash your hands
3, check the "equipment"! Carefully check insulin type, dose, character, injection time and expiration date.
Remove the insulin 30 minutes in advance to warm up at room temperature (injection of cold insulin will cause pain).
Note: Pre-mixed insulin needs to be shaken in advance! The pen should be reversed several times before use until a white suspension is produced. Specific practice: Put the insulin pen flat in the heart of your hand, roll it horizontally 10 times, and then turn it up and down 10 times by swinging the elbow joint and forearm, so that the medicine liquid in the bottle is fully mixed until the insulin is transformed into a uniform white liquid.
Two, start the injection! Remember these five steps
● Correct procedure for insulin injection:
1. Install insulin pen refill; 2. Install the needle; 3. Exhaust; 4. Select the injection site for injection; 5. Remove the insulin needle for treatment.
The process is simple, so how exactly do you do it?
Today, the Endocrine Channel of the medical community specially invited the little sister of the endocrinology and metabolism Department of West China Hospital of Sichuan University to demonstrate the operation process of correct insulin injection. Quick poke video! � �
After watching the video, do you feel that the injection of insulin is not so difficult? But what do you know about some of the common steps in the injection process?
3. Please take care of the 8 precautions during injection!
1venting
Exhaust and adjust the dose, remember to exhaust the air in the refill before each use and after updating the refill.
Before injection, turn the dose adjustment knob to 2U.
The tip of the needle is upright, the finger taps the pen refill holder several times, so that the air accumulates in the upper part, and presses the injection key until a drop of insulin spills from the needle, which means that the drive rod has fully contacted the pen refill and the bubbles in the pen refill have been drained.
Note: Check doctor's orders and adjust dosage to desired scale.
2Disinfection of the injection site
Please avoid subcutaneous fat hyperplasia, fat atrophy, and ecchymosis injection.
The correct disinfection method, centered on the injection point, disinfect the skin with alcohol from the middle to the surrounding area, with a diameter of about 5cm, where the alcohol has been wiped, do not wipe again to reduce pollution.
Note: Do not use iodophor disinfection, because insulin is a protein, disinfection with iodophor can affect insulin activity.
3Choice of insulin injection site
The suitable places for insulin injection are abdomen, outer thigh, outer upper arm and outer upper hip.
Abdomen: Insulin absorption rate reaches 100%, suitable for injection of short-acting and ultra-short-acting insulin;
Outer upper arm: Insulin absorption rate was 85%;
Outer thigh: The insulin absorption rate is 70%, pinch the skin for injection, suitable for injection of long-acting insulin;
Outer upper side of buttocks: insulin absorption rate is the slowest, no need to pinch skin injection, suitable for injection of long-acting insulin.
4Rotation of injection sites
Rotation of injection sites can effectively prevent subcutaneous fat hyperplasia, which includes rotation between different injection sites and rotation within the same injection site.
Insulin injection site
Rotation of different injection sites, according to the morning, middle, evening, different time on the same day, select different sites for injection.
For the rotation within the same injection site, take the abdomen as an example, the abdominal injection area is divided into 4 equal subregions by "cross", avoiding the umbilical circumference, using one equal subregion every week and always rotating in a clockwise direction.

5How to inject
The general injection technology advocates is "fast into the needle, fast out of the needle, slow push medicine", which is a painless injection technology.
6When do I need a pinch injection
Whether the skin needs to be pinched during injection is a problem that patients have been very concerned about. Many patients do not master the injection technique, easy to inject insulin into the muscle layer. Not only does this increase pain and make the patient resistant to insulin injections, it can also lower blood sugar levels too quickly, threatening hypoglycemia. Therefore, medical staff should educate patients to use the correct manipulation and appropriate length of needles for injection.
In general, patients who are overweight or have a body mass index (BMI) >22kg/m2 do not need to pinch the skin when injecting in the abdomen, but need to pinch the skin when injecting in the thigh to ensure that the solution is injected under the skin. For patients with lean or low body fat rate, the skin needs to be pinched when injected, otherwise it is easy to inject into the muscle layer.
7Needle change
Insulin pen injection needles should be changed before each use, and each change should be vented. Due to the limited economic conditions, most patients in our country have repeatedly used needles.
8Insulin preservation
Insulin is a delicate protein molecule that is easily destroyed by heat, freezing or agitation. Below zero, insulin activity will be destroyed, above 30℃, insulin activity will be reduced.
Any unopened bottle or pen refill insulin should be stored in the refrigerator (2 ° C ~ 8 ° C), only opened insulin in use can be stored at room temperature (≤25 ° C or 30 ° C), the specific situation should also refer to the product instructions.
