Information

Intravenous fluids are a traumatic treatment, and venipuncture can cause pain and cause vascular damage. Clinical studies are mostly based on the angle, length, direction, and technique of needle insertion, ignoring the problem of needle size, especially for intravenous infusion of tumor chemotherapy patients. Adults are used to choosing No. 7 scalp needles. Because the diameter of the 6-gauge scalp needle is smaller than that of the 7-gauge scalp needle, the amount of contact between the laminar liquid medicine and the blood vessel wall is reduced, and the irritation of the medicine liquid on the blood vessel wall is  reduced.

The No. 7 scalp needle of the disposable infusion set has a thick needle, and the area of ??damage to the subcutaneous tissue and blood vessel wall is large, so the pain is more pronounced. When the mechanical, thermal or chemical irritation acting on the skin exceeds the response threshold, it will cause pain. The double damage of the venous vascular intima by the chemical stimulation of the drug and the mechanical impulse of the needle can easily cause pathological changes in the vascular intima and increase the intensity of vascular destruction.

The tube diameter of No. 7 scalp needle> No. 6 scalp needle has high mechanical force, and it is easier to exceed the pain threshold and cause pain. Therefore, the pain of the scalp needle is reduced during intravenous chemotherapy puncture and infusion. According to clinical practice research, the fastest infusion speed can reach (90~10) drops/min (when the infusion height is 100cm) with a 6-gauge scalp needle to puncture the vein on the back of the hand. Therefore, the ideal infusion speed can still be achieved with the use of No. 6 scalp needle, without affecting the treatment.

The precision infusion set can effectively filter the infusion particles, the disposable infusion set can effectively prevent or reduce phlebitis, and the No. 6 scalp needle has less damage to the blood vessels than the No. 6 scalp, which can significantly reduce the pain of the blood vessels, thereby reducing the pain of chemotherapy patients and ensuring the chemotherapy regimen The smooth implementation has improved the cure rate of tumors.
