Location: veins of limbs, usually injected into the back of hand, easy to fix and walk. If the blood vessel is flat, it is difficult to find it because of frequent injection, so it is injected at the foot. Materials: tourniquet, sterile cotton wool, bandage, infusion set. Steps: First sterilize the bottle mouth, hang it upside down on the infusion stand, insert the infusion set into the bottle mouth, exhaust the air inside, and find the vein.
Tie a tourniquet about 3 ~ 5 cm above the needle entry site (if the patient clenches his fist on the back of his hand to make the blood vessels easy to find), then sterilize the injection site, insert the needle, immediately loosen the tourniquet when the blood returns, put a cotton head on the needle, fix it with a bandage, fix the infusion tube with the remaining bandage, and adjust the dropping speed of the liquid medicine. Generally, 30-40 drops a minute is appropriate.
The speed depends on the efficacy of the drug. The smaller the needle insertion angle, the greater the resistance. There are many experienced nurses in the clinic. There is no 1, 2, 3 steps in needle insertion (breaking skin, entering blood vessels, reducing the needle insertion angle), and the needle is directly stepped over 45 degrees. The resistance mentioned here should be negligible, and everyone can do it according to their own skilled methods.
Note: the infusion set should be completely emptied of air, and it is not easy to insert the blood vessel too deep. After insertion, wait for two or three minutes to see if there is a drum at the place where it is tied. If it is necessary to put the roller aside, it should be fastened again.
