Precautions for use of anti acupuncture blood collection needle

1. Precautions for unpacking blood collection needle packaging

When unpacking the whole box of blood collection needles, pay attention to the validity period of blood collection needles. Expired products cannot be used. When unpacking the blood collection needle, pay attention to that the outer package is not damaged. If it is damaged, it cannot be used.

2. Preparation of blood sampling needle before puncture

After tearing the outer package of disposable blood collection needle, hold the needle tip and tail of the blood collection needle with both hands respectively, and tighten the hose of the blood collection needle. Explanation: the disposable blood collection needle is wrapped and placed in the outer package, and the crimped hose has a certain elasticity. In the process of blood collection, the needle tip is easy to slide out of the patient's body due to the elasticity of the hose. Some hoses have great elasticity. After the needle tip slides out of the patient's body, the high-speed rebound pierces the operator's hand fixing the blood collection vessel, resulting in occupational exposure. If the hose can be tightened before puncture to make it lose elasticity, the needle tip can be prevented from sliding out of the patient's body due to the elasticity of the hose, and the needle tip can not continue to rebound and puncture the operator's hand fixing the blood collection vessel after sliding out of the patient's body.

3. Precautions for blood collection of special blood collection vessels

If Di a tube is encountered, it is a blue headed tube (coagulation detection tube) or a black headed tube

(ESR detection tube), the disposable blood collection needle should be inserted into the patient's blood vessel. After seeing the blood return, remove the rubber protective sleeve at the tail of the blood collection needle to make the blood flow naturally along the hose to the tail, and then insert the tail of the blood collection needle into the center of the rubber plug of the blood collection vessel. Reason explanation: the negative pressure of blue head tube and black head tube is insufficient. If it is di one tube for blood collection, if the air of the disposable blood collection needle hose is not discharged (the volume is about 0.3 ~ 0.4 ml, and the data is provided by the manufacturer), the blood collection may not reach the specified scale mark.

4. Precautions for blood collection acupuncture into blood collection vessels

When inserting the tail end of the blood collection needle into the center of the blood collection rubber plug, first hold the tail end of the blood collection needle with the thumb, index finger and middle finger of the right hand, make the tail end of the blood collection needle and the plane of the blood collection rubber plug form an included angle of about 45 °, and make the middle finger and the blood collection rubber plug close and fixed, and then turn the right hand with the middle finger as the support point to make the tail end of the blood collection needle vertically penetrate into the center of the blood collection rubber plug. This technique can better prevent the tail of the blood collection needle from slipping out when it pierces into the center of the rubber plug of the blood collection vessel and hurting the hand of the blood collection operator.

5. Precautions for operators during blood collection

When collecting the patient's blood, the left hand holding blood collection vessel should be placed on the operating table for fixation to prevent the hand holding blood collection vessel from hanging unsteadily and pulling the blood collection needle out of the patient's body.

6. Treatment of special circumstances in the process of blood collection

In case of poor blood absorption during blood collection, on the premise of ensuring the success of venipuncture, adjust the position of the needle tip, rotate the needle or push the needle slightly to let the blood flow into the blood collection vessel.

7. Treatment of residual blood in the hose of blood collection needle

When collecting blood samples, the negative pressure of the test tube has been exhausted. The blood left in the blood collection needle after pulling out the needle cannot continue to enter the test tube, which is easy to make the blood in the blood collection needle drip and pollute the operation table and the operator. Therefore, after blood extraction, the tourniquet should be loosened first, the puncture needle should be pulled out, and then the blood collection needle and vacuum tube should be separated to make all the blood in the silica gel hose of the blood collection needle enter the blood collection vessel.

8. Treatment of blood collection needle after blood collection

After blood collection, the used blood collection needles should be properly put into the disposable sharp weapon box and destroyed in a centralized manner.
