With the wide application of the needle-free injection principle, it has attracted more and more people's attention. Some people are still unfamiliar with how to use the needle-free insulin syringe. Next, I will briefly introduce how to inject insulin with the needle-free syringe.

Method/step:

1. Pressurized
Take off the end cap, twist and tighten the drug tube to the Quick Shure needleless syringe, and then rotate the lower shell of the syringe according to the instructions on the syringe, and pressurize the syringe until it does not rotate and the pressure is completed. Clearly visible safety lock and injection button pop up

2. Taking medicine
Connect the needle-containing end of the drug-taking interface to the insulin refill, and the needle-free end to the drug tube of the needle-free syringe; keep the syringe upright, and rotate the lower shell of the needle-free syringe according to the indication on the needle-free syringe. A small amount of air will remain in the drug tube or interface. To ensure the accuracy of the injection dose, please absorb 2 more units of insulin for exhaust use.
If there are air bubbles on the tube wall of the medicine tube, tap the end with air bubbles, and then rotate the syringe to remove the air bubbles.

3. Injection
Please sit on a chair when injecting, and bend your back properly to fully relax your abdomen. The injection site should be 2.5 cm away from the belly button (the softest place other than the three fingers is recommended). After the disinfection site is dry, place the front end of the drug tube perpendicular to the injection site Press firmly, hold the safety lock with your index finger and press the injection button with your thumb.
Please rotate the injection from left to right. Do not inject multiple times in the same area. After the injection is completed, please keep the injection state for more than three seconds, then remove the needle-free syringe and press it with a dry cotton swab for more than 10 seconds.
For patients with poor coagulation function or long-term use of anticoagulant drugs, it is recommended to extend the compression time by 10 seconds to 30 seconds.

Precautions:
The maximum injection dose is 35 units. If the injection dose is large, it needs to be divided into 2 injections.
The operation steps of each brand of needle-free syringes are slightly different.
Pay attention to the pressing time after injecting insulin due to individual differences.
