Blood Draw Syringe

Blood Draw Syringe - Copyright © 2010, world health organization. Once blood is seen in the tubing, connect the vacutainers or use a syringe to draw the needed amount. In venous blood sampling, a needle is inserted into a vein to collect a sample of blood for testing. Properly label the tubes (at the bedside) and send them to the laboratory for analysis. This chapter describes only the procedure for a radial artery blood draw. Several different arteries can be used for blood collection. A syringe draw is a much more appropriate technique for you to use with veins that easily collapse. Hypodermic needles are used with syringes and butterfly needles come as a unit, the needle connected to a 12 inch tubing at one end and a connector (luer adapter) at the other end. A medical professional will use a butterfly needle to draw your blood or to try and access a vein to give intravenous (iv) medications. Slight adjustments in angle during filling might fix this.

Multiple drawing needles are screwed unto a tube holder and used with vacuum tubes for blood collection. Your needle is at a shallow angle and the bevel may push up against a vein wall. Peripheral veins, typically the antecubital veins, are the usual sites for venous blood sampling. Slight adjustments in angle during filling might fix this. When drawing blood samples, a syringe allows healthcare professionals with blood collection responsibilities to control the negative pressure and prevent collapsing veins. The information given in this appendix is based on advice from the centers for disease control and prevention (5). The 21g needle is one of the larger gauge sizes commonly used for blood drawing procedures. Failing to adhere to this order can lead to inaccurate lab findings, impacting patient diagnosis and treatment. Gather the necessary equipment and tools used to perform the blood draw and place them on a tray that's within reach. The first step in drawing blood correctly is to identify the appropriate veins to puncture.

The syringe method is safer for those veins because you can control the pressure and speed at which blood is drawn. If using a syringe, first expel all air out of the syringe and make sure the plunger moves freely so it’ll be easy to operate when drawing blood. This chapter covers all the steps recommended for safe phlebotomy and reiterates the accepted principles for blood drawing and blood collection (31). Gather the necessary equipment and tools used to perform the blood draw and place them on a tray that's within reach.
