Introduction
In general, the difference between 3-bevel and 5-bevel insulin needles lies in differences in user experience, pain sensation, and injection accuracy. Before injecting insulin, patients should expel all air from the syringe to ensure accurate insulin dosage. Patients should note that insulin injection needles are for single use only and must be discarded after use to prevent infection.
Generally, the differences between 3-bevel and 5-bevel insulin needles lie in user experience, pain level, and injection accuracy. The specific details are as follows:
1. Different User Experience
A 5-bevel insulin needle penetrates the skin more easily and provides a more comfortable experience compared to a 3-bevel insulin needle.
2. Different Pain Sensation
When using a 3-bevel insulin needle for injection, there may be a slight sensation of pain. In comparison, a 5-bevel insulin needle causes less pain than a 3-bevel needle.
3. Different Injection Accuracy
The 5-bevel needle design features lower penetration force. Additionally, ultra-thin or extremely thin wall needles with larger inner diameters can effectively improve injection accuracy.
Before injecting insulin, patients should expel all air from the syringe to ensure accurate dosing. Patients should note that insulin injection needles are for single use only and must be discarded after use to prevent infection. If any discomfort occurs, patients are advised to seek medical attention at a hospital promptly.
