Needles Only — Hypodermic Needle, Choose the Right Needle Selection Criteria Guide

Hypodermic Needles are used to inject medications for patient care. Choosing the Right Needle can be a daunting task because modern Hypodermic Needles come in many sizes and options, including PrecisionGlide Needles, Sterile Hypodermic Needles, Thin Wall Needles, Insulin Needles, Pen Needles and Winged Needles.

Medical Needles (see Anatomy of a Needle) are selected most often by the intended use or the injection type. The basic types of patient injections for patient care include intradermal injections, subcultaneous injections and intramuscular injections (see Needle Selection Criteria). Important criteria for selecting the correct needle size include the needle gauge (see Needle Gauge Selection Criteria), the needle length (see Needle Length Selection Criteria) and the type of syringe connection (see Syringe & Needle Tip Selection).

Needle gauge is a measurement of the diameter of the needle, the larger the needles gauge number the thinner the diameter. The higher the viscosity of the fluid being injected, the lower the needles gauge number should be. However, the higher the needle gauge number, the less pain and bruising for the patient. Needle length is usually provided in inches. Half inch to 5/8 inch needles are the most often selected needle length for intradermal and subcutaneous injections. Intramuscular injections usually call for a needle length of 7/8 inch to 1-1/2 inch.
