Video tutorials on the use of indwelling needles are as follows:
1, strict implementation of aseptic technical operation: before performing the operation of indwelling needles, it is necessary to strictly implement the aseptic technical operation, such as washing hands, wearing a mask, etc., in order to reduce the risk of infection.
2, the correct choice of blood vessels: choose thick and straight, good elasticity of the blood vessels for puncture, and avoid joints, so as not to repeatedly twist the cannula when the limb movement.
3, protect the indwelling needle: during the use of the indwelling needle, it is necessary to protect the indwelling needle, such as avoiding excessive activities, do not use cosmetics around the needle, etc., so as to avoid infection or dislodgement of the indwelling needle.

What is an indwelling needle
01
Venous indwelling needle is a puncture treatment method for those who are not good at finding blood vessels, not good at injecting, the old and the weak, the rescue or frequent venous puncture and so on. It is used only once after the infusion is finished, because the needle in front of it is a soft needle, not a steel needle, so it will not cause leakage, puncture blood vessels and other accidents. Then seal the tube with heparin solution so that the needle will not solidify.
02
The indwelling needle is buried in the blood vessel and does not need to be lifted. Before the next IV infusion just flush the tube to connect the infuser, no needles that is to reduce the pain of your injection.
03
The intravenous indwelling needle is also known as an intravenous cannula needle. The core components include a flexible catheter/cannula that can be left in the blood vessel, and a stainless steel puncture guide insert. The catheter and the needle insert are punctured into the blood vessel, and when the catheter is completely in the blood vessel, the needle insert is withdrawn and only the soft catheter is left in the blood vessel for infusion therapy.
04
The indwelling needle is divided into open type and closed type, open type is divided into normal type and safety type (anti-needle-stick type), closed type is divided into normal type and safety type (anti-needle-stick type).
05
Scope of application: intermittent, continuous or daily intravenous fluid therapy. The use of scalp steel needles should be limited to short-term or single-dose administration for collection of blood samples or transfusion of blood or blood products, hemodynamic monitoring of the infused fluid at or near isotonicity, and normal pH range (stimulant medications: intermittent push only).
