Blood collection systems for professional blood collection
In human medicine, blood is collected either for diagnostic or therapeutic purposes, e.g. for creating a haemogram or for blood gas analysis procedures. For diagnostic blood collection, a defined amount of blood is drawn and collected in a syringe or in a special blood collection tube. These blood sample tubes come with a preparation that prepares the collected blood for later examination. Depending on whether the exam is to take place with serum, plasma or whole blood, special ingredients like citrate or EDTA needs to be added to the blood sample.
Aspiration Systems & Vacuum Systems for Blood Collection
A distinction is made between 2 blood collection systems - the aspiration system and the vacuum system. The most common representatives of these two blood collection systems are the monovette (aspiration system) and the Vacutainer (vacuum system). Both blood collection systems allow a quick and clean blood collection and can be used for both adults and children.
Performing a Venous Blood Collection
After the preparation of the necessary materials such as gloves, (butterfly) needle, swab, tourniquet, disinfectant, collection tubes, instruments for sample collection and adhesive plasters in the laboratory, and disinfection of hands, you can begin with the venipuncture procedure.
- Congestion - congest the vein to be punctured approximately 7.5 cm above the desired puncture site.
- Select venipuncture site - preferred veins such as the cephalic vein or the median cubital vein
- Disinfecting the venipuncture site - please read the information provided by the manufacturer of the disinfectant.
- Gloves - should be put on now at the latest
- Preparing the venipuncture instruments - e.g.screw the holder onto the cannula.
- Venipuncture- for venipuncture, you should make sure that the needle opening is facing upwards.
- Loosening the tourniquet- release the tourniquet as soon as the first drop of blood flows into the tube.
- Swirling the tubes - tubes with additives such as EDTA need to be swirled after removal according to manufacturer's instructions
- Finishing the venipuncture procedure- place the swab on the cannula (be careful not to apply pressure), apply pressure with the swab on the puncture site after pulling out the needle
- Disposal - the needle and contaminated consumables should be disposed of in an appropriate sharps container.
- Treat the venipuncture site - bandage the skin as quickly as possible with a plaster or bandage, instruct the patient to continue to apply pressure to the puncture site for 3-5 minutes.
Warning: To prevent contamination caused by the additives in some of the tubes, you should always be careful to use the tubes in a distinct order during routine venipuncture. It is particularly important to ensure that EDTA tubes are taken after serum or heparin tubes. If you wish to collect a single citrate tube using a butterfly needle, a tube with a neutral filling must first be collected and discarded so that a specific filling is possible.
Phlebotomy: Therapeutic Bloodletting
Therapeutic bloodletting is also known as phlebotomy. This form of therapy is used for patients suffering from haemochromatosis, polyglobulia or polycythaemia vera, for example. Blood collection through phlebotomy is usually performed by a phlebotomist out with the help of special phlebotomy supplies and a vacuum bottle in which the let blood is collected to be disposed of later.
