Injection Syringe

Injection syringe – a cylindrical device with a cannula-like nozzle, with or without a fixed needle and a movable piston, used for the administration, usually parenteral, of an accurately measured quantity of a liquid pharmaceutical form. The syringe may be prefilled, and can be for single-dose or multi-dose use.

Types of Injection Syringe

  1. Hypodermic syringes - calibrated (marked) in cubic centimeters (cc), milliliters (mL), or units. Practitioners often refer to syringes by the volume of cubic centimeters they contain, for example, a 3 cc syringe.
  2. Oral syringes - used for the transport and administration of non-injectable liquid medication. The oral syringes’ assembly usually consists of a polypropylene barrel imprinted with a graduated scale in milliliters and barrels are available in either clear or amber.
  3. Insulin syringes - used for the subcutaneous injection of insulin and are calibrated in units rather than milliliters. Insulin is a hormone used to treat patients who have insulin-dependent diabetes mellitus (IDDM). It is supplied as a premixed liquid measured in standardized units of potency rather than by weight or volume. These standardized units are called USP units, which are often shortened to units. The most commonly prepared concentration of insulin is 100 units per milliliter, which is referred to as units 100 insulin and is abbreviated as U-100 on insulin labels.
  4. Tuberculin syringe - is calibrated in hundredths of a milliliter. Because there are 100 lines on the syringe, each line represents 0.01 mL. This syringe is used for intradermal injection of very small amounts of substances in tests for tuberculosis and allergies, as well as for intramuscular injection of small quantities of medication. The tuberculin syringe is the preferred syringe for use in measuring medications less than 1 mL.
