The butterfly venipuncture needle, also known as a winged infusion set, was invented by Dr. Richard M. Knapp in the 1940s. This design features plastic "wings" that facilitate easier handling and stabilization during venipuncture. It is widely used for drawing blood or administering medications, especially in patients with small veins or when a more delicate approach is needed.
What else can I help you with?
What is the method venipuncture when drawing blood from a 75 years old patient with thin veins?
A butterfly needle with tube and vacuum syringe.
What are the three methods of venipuncture?
The three methods of venipuncture are vacuum method (using a vacuum tube system to collect blood), syringe method (using a syringe to manually draw blood), and butterfly method (using a small butterfly needle for difficult veins or sensitive patients).
When was the butterfly needle invented?

What is another name for winged infusion set?
Another name for a winged infusion set is a "butterfly needle." This device consists of a hollow needle with two flexible "wings" on either side, which help secure the needle in place during venipuncture. Butterfly needles are commonly used for drawing blood or administering medications in small veins.
What is the advantage of using a butterfly needle withe syringe?
The advantage of using a butterfly needle with a syringe lies in its design, which allows for greater flexibility and stability during venipuncture. The wings of the butterfly needle provide better control, making it easier to insert and secure the needle, especially in smaller veins. This is particularly beneficial for pediatric or geriatric patients, where veins may be more challenging to access. Additionally, butterfly needles can reduce the risk of dislodgment, leading to more comfortable and efficient blood draws.
Why is a 21 gauge needle recommended for venipuncture?
The 21 gauge is a smaller needle.
What needle is used when drawing blood from the feet?
When drawing blood from the feet, healthcare professionals typically use a butterfly needle or a small-gauge needle, such as a 23-gauge or 25-gauge needle. Butterfly needles are preferred for their ease of use and maneuverability in smaller veins. It's essential to ensure proper technique and site selection to minimize discomfort and complications. Always follow institutional protocols for venipuncture.
What degree is the angle used between the skin and needle when using a butterfly collection system?
When using a butterfly collection system, the angle between the skin and the needle is typically around 15 to 30 degrees. This angle helps to ensure that the needle enters the vein smoothly while minimizing discomfort for the patient. Proper angling is crucial for successful venipuncture and reducing the risk of complications.
The slant at the open end of a needle used for venipuncture is termed the?

The insertion of a needle or cannula into a vein for the purose of withdrawing blood is?

What needle is used for chemotherapy?
A small, thin needle called a butterfly needle or a catheter needle is commonly used for chemotherapy. These needles are designed to be gentle on veins and can accommodate the flow of chemotherapy drugs.
What size needles are used for routine butterfly venipucture?
For routine butterfly venipuncture, 21-gauge or 23-gauge needles are commonly used. The 21-gauge needle is typically preferred for adults due to its larger diameter, allowing for faster blood flow, while the 23-gauge needle is often used for pediatric patients or those with smaller veins. The choice of needle size may also depend on the specific requirements of the procedure and the patient's condition.
