Application of venous blood collection needle

1. Used for peripheral venous blood collection After the blood vessel is selected, the conventional scalp needle is used to puncture the needle. After seeing the return of blood, fix the needle head with the infusion sticker, fix the needle handle and the fixed connector with the left finger, and hold the vacuum test tube in the right hand, and pierce the end of the blood collection device into the Vacuum test tube. Before blood collection, the blood collection test tube should be selected, and the tube should be changed immediately after one tube is collected. The needle insertion angle for blood collection is selected according to the patient's fatness and thinness, and the condition of blood vessels.

2. For femoral vein blood collection For patients with hemorrhagic shock, general edema, and other patients with difficulty in extremity vein blood collection, the success rate of femoral vein blood collection using a vacuum venous blood collection needle is high. After routine disinfection of the skin, the operator holds the blood collection needle in his right hand and inserts the needle at a 90° angle to the skin at the position of the femoral vein. Stop inserting the needle after seeing the return of blood, fix the right hand, hold the vacuum blood collection tube in the left hand, insert the needle into the test tube, and the blood will flow into the test tube automatically. Withdraw the needle after the desired blood volume is achieved.

       3. Use vacuum blood collection needles for series infusion, flushing or pouring, connect two or more bottles of the same or no incompatibility liquids in series for infusion or flushing, and use blood collection needles to collect blood before infusion.
