How to use blood collection needle correctly?
Take out the arterial blood collection needle from the sterile packaging.
Remove the arterial blood collection needle cap and put it in a proper position.
Move the needle cap outward.
Push the mandrel forward to the zero scale line and then withdraw it to the desired scale.
The arterial blood collection needle is punctured at an angle of 45° to 90°.
Fill the sample to the preset scale under arterial pressure.
After the sample is collected, immediately pull out the needle of the arterial blood collection needle and press the puncture point with gauze for at least 5 minutes to prevent bleeding.
Strictly speaking, it cannot be reused. Once the blood collection needle is used, its needle point is no longer sharp, and the needle point will become more and more blunt as the number of times of use increases. When blood is drawn, there will be increased pain due to the blunt tip of the needle. It should be noted that bacteria are prone to multiply on used blood collection needles, which may directly endanger health. Therefore, after the blood sugar test is completed, the used test strips and blood collection needles should be disposed of properly immediately.
The blood collection needle should be used together with the sample tube for blood collection. As the needle performer, you must first select the blood vessel, usually the median vein of the elbow, (that is, the middle of the elbow, you can touch it) choose a thick and straight blood vessel, and then carry out routine disinfection , pull out the small cap, tie the tourniquet, and you can puncture. After seeing the blood returning, loosen the tourniquet, (the needle handle does not need to be fixed, and the needle will not run away) free your hand to directly insert the other end of the blood collection needle into the rubber stopper of the specimen tube mouth (There is negative pressure in the specimen management, and the blood will run in by itself.) When the blood stops flowing, first pull out the needle that punctures the blood vessel, and then pull out the needle at the mouth of the tube. Instruct the patient to press for 5 minutes without rubbing. After shaking for 6 times, the operation is completed.
