A needle is a thin, sharp object used for piercing the skin. A hypodermic needle is specifically designed for injection of medications and other fluids beneath the skin. When used for donating blood, a hypodermic needle is inserted into a vein and the blood is drawn out.
The needles used for donating blood are usually disposable and are supplied by the donation center. They are sterile and have a sharp point that minimizes the risk of injury. The needles are inserted into a vein in the arm and the blood is drawn out using a vacuumlike device.
The needles are only used once and then discarded. They are not reused because of the risk of infection. The needles are also very sharp and can easily injure the donor if they are not handled properly.
Donating blood is a safe and easy way to help others in need. The needles are sharp, but they are also very safe. They are used once and then discarded, so there is no risk of infection.

When a person needs to have blood drawn, a health care professional will use a needle to extract blood from the person.

Some health care professionals also use a 14-gauge needle for blood draw. A 14-gauge needle is thick and it is a good choice for people who have a lot of veins that are difficult to find. However, it is also more likely to cause bruising.
