People often associate blood tests with pain or a certain fear of pain caused by the pricking of the needle. If you’re one of these people who fear needles, fret not. There is a certain high-end technology needles called Butterfly Needles that can make blood testing a pain-free experience.
It is called butterfly needles because the needle has wings like a butterfly. Dr. B.R. Das, President-Research & Innovation, Mentor-Molecular Pathology and Clinical Research Services states that this Butterfly Needle Technology was particularly introduced to reduce the pain experienced during phlebotomy (blood collection). This endeavour aims to minimise the pain and psychological fear associated with blood tests.
Butterfly needles also minimises accidental needle injuries that are otherwise common in the healthcare system. This makes this technology a relatively safe procedure.
How does it work?
The phlebotomist (person who collects blood) holds the needle by the folding ‘wings’ and inserts it into the vein. Once the needle is into the vein, you will see a ‘flash’. This flash is basically a small amount of blood that flows to a hub connected to a needle.
The butterfly needle is recommended to be used in the following group of people
- With very small and fragile veins, e.g. hands, feet
- In newborns
- Patient’s with tremors or uncontrolled movements
- PAXgene tube collections
- Have syringe phobia (entetophobia)
- On patient or physician requests
It is important to note that these butterfly needles are more expensive than regular needles and it is less readily available than straight needles in medical stores.
