What is the purpose of the bevel on a needle?

The bevel on a needle serves a crucial role in facilitating easier penetration of the skin or tissue. Its design creates a sharp point that enhances the cutting ability of the needle, making it more efficient for insertion into various types of tissue. When the needle enters the skin, the angled bevel allows for a smoother entry, reducing trauma to the surrounding area, which can help minimize discomfort for the patient during procedures like injections or blood draws. This sharp point is essential for achieving quick and effective access to the bloodstream or tissue without causing unnecessary damage.

While securing a grip or measuring dosage might involve other aspects of needle design or handling, these are not the primary purposes of the bevel. The bevel is specifically engineered to ensure optimal performance in penetration, making it vital for successful and safe needle usage in clinical settings.
