The process before using the injection pen
CHECK: Check the name of the medicine and the coloured label before use to ensure it is the correct medicine and dose. Remove the cap and ensure that the solution in the pen is clear and colourless. Do not use if the solution appears cloudy or discoloured.
Rewarming: if you take it out of the fridge, be sure to rewarm it. If you load the needle for injection right away, the temperature is too low this time of year and it is more irritating for you, making it painful or uncomfortable to hit. How do you rewarm it? Let it sit at room temperature for a while, usually 10 minutes or so, and it gradually reaches room temperature. Never grill it over a fire or heat it in any other way.
Hand washing: clean your hands before injection. If I take a large pair of dirty hands to sterilise them when injecting, the efficiency and reliability of sterilisation is reduced and there is a risk of secondary contamination.
Syringe pen mounted needle
Selection of needles: needles should not exceed 8 mm and be disposable. A new needle is required for each injection, which reduces the risk of needle clogging, contamination and inaccurate dosage.
Installing a new needle: Peel off the protective sheet of the needle. Fit the needle and tighten it. Align the needle when fitting it, don't fit it crooked. If you don't get it right, it can easily cause a bend inside the needle. This makes the injection very unpleasant and can also cause the drug inside the needle to crystallise.
Remove protective sheet before installation
The inner needle cap can be thrown away and the outer needle cap must be retained: Attach the needle to the injection pen and remove the outer needle cap and the inner needle cap in turn. The inner needle cap can be thrown away, the outer needle cap must be kept. After the injection, you still need to use this needle cap to safely unscrew the needle from the injection pen.
Exhaust
New injection pens should always be vented before use. If this is not done, then the dose may not be set correctly. You don't have to worry about consuming the amount of medication when you do the venting, because, in each injection pen, there is already a sufficient amount reserved for venting, so you won't let it go to waste.
If the injection pen has been used, there is no need to exhaust this operation. It is normal that a drop of solution may appear at the mounted tip of a used syringe.
Turn the dose selection button until the pointer is aligned with the airflow check mark (- - - -): with the needle pointing upwards, keep pressing and holding the administration button until the display in the dose display window returns to position 0. The 0 must be aligned with the dose pointer. After this operation, a drop of solution should appear at the tip of the needle, which ensures solution fluidity. If no drop appears, repeat the above operation to expel the air. Repeat this operation up to 6 times. If you never see a droplet of solution, replace the needle and exhaust the air again. A small air bubble may remain at the tip of the needle after deflating, this is fine, the bubble will not be injected into the body. Air Exhaust:
NOTE: Be sure to remove air each time when you use a new syringe pen for the first injection.
Selecting the dose
We will now start to select the dose for the injection dose adjustment by selecting the knob so that the display shows the therapeutic dose you need to inject. The selected dose shown in the dose display window must be perfectly aligned with the dose pointer to ensure that you receive the correct dose.
Skin inspection and sterilisation before injection
Inspection of the injection site: first check the skin for allergies, fatty growths, hard nodules, danger of skin depressions with ecchymosis.
First check and then disinfection: use alcohol cotton pads or cotton swabs to disinfect the skin. It is better to sterilise the injection site with alcohol swabs. It is not impossible to use cotton swabs. Cotton swabs usually come in packs of 50 or 60, and opening them over and over again makes them more prone to secondary contamination. Alcohol swabs are now disposable and the overall cost is not very high, but the risk of secondary contamination is significantly reduced. Remember where to sterilise.
Wait for the alcohol to evaporate before injecting: Waiting for the alcohol to evaporate and dry before injecting can reduce pain, otherwise the residual alcohol will increase the irritation and increase the pain when injecting.
Small details on the use of injection pens
Simeglutide is administered by subcutaneous injection at a site of choice in the abdomen, thigh or upper arm. No dosage adjustment is required to change the injection site.
Insert the needle into the skin and press the injection button continuously downwards. The action of sticking the needle into the skin should be slightly faster. The pain is a little more pronounced with a slower zap. Once the needle is in, push the injection button slowly, gently, and consistently at an even rate. The injection speed should not be too fast to avoid spillage, nor too slow to avoid constant irritation and increased injection pain.
When the dosage pointer reaches 0, it indicates that the injection is complete.
Do not rush to pull out the needle after injection, maintain the needle placed under the skin for at least 6 seconds after pulling out the needle to ensure that the medicine is injected fully: never rush to pull out the needle after injection, let the needle stay inside the skin for a little longer. Let the needle stay in the skin for a while. We will count 6 times, the main purpose of counting these 6 times is to let the medicine enter into the subcutaneous fully. If you pull out the needle too early after the injection, it is possible that the drug has not yet fully entered the skin. Stay under the skin for 6 seconds to ensure that all the medicine is injected into the body.
Needle feeding details of the injection pen
Our skin from outside to inside is: epidermis → dermis → subcutaneous (ideal absorption area) → muscle.
The goal of subcutaneous injection is to deliver the drug to the subcutaneous tissue
When injecting with needles of different lengths (in mm), the angle of needle insertion is different: with shorter (4 mm or 5 mm) needles, most adults do not need to pinch the skin and can insert the needle at 90°; with longer (≥6 mm) needles, it is necessary to pinch the skin and/or insert the needle at 45° in order to minimise the risk of inserting the needle into the muscle. In short, for fat people, when punching the tummy, the needle is basically in this position under the skin, without pinching the skin, and can't penetrate into the muscle. For thin people, with a long needle may be stuck in the muscle, this time to pinch the skin.
Tips for when you've finished using the pen
Remove the needle from the skin, if the injection site is dangerous, just press gently, do not rub the injection site. After the injection is complete, you may see droplets hanging from the tip of the needle, this is normal and will not affect the dose you give.
The needle should be removed after each injection. This prevents needle blockage, contamination, solution leakage, and inaccurate dosing. Please insert the needle tip carefully into the outer needle cap cover on a flat surface and hold it in place with the outer needle cap left in place. It will be possible to remove this needle tip. Unscrew the needle tip and dispose of it by safely discarding it. Slip the cap back onto the injection pen to protect it from light.
Used injection needles are medical sharps and improper disposal can cause needlestick injuries as well as environmental contamination and hazards.
Use a sharps box to store discarded pencils and needles, and when it is almost full, bring it to the hospital when you visit and throw it in the yellow medical waste bag.
If you don't have a sharps box, buy a plastic milk bottle in a stylish packaging or a stylish wide-mouth bottle like Pulse. Whether it's a pen refill, a needle, or a cotton swab, you can stuff it into a wide-mouth bottle. If you use a narrow-mouth bottle like a mineral water bottle, the entrance is too small and you might get yourself stuck. Therefore, it is better to use a wide-mouth bottle with a closed lid. Keep it out of the reach of children.
