“Syringe” refers to is a medical device used for injecting or withdrawing fluids. A syringe can include several basic parts: a barrel, a plunger, a needle, a tip/cap, a luer lock / luer slip, plunger seal/gasket, and/or a flange.
A barrel is a main body of the syringe, usually made of plastic or glass, which holds a fluid to be injected or withdrawn. The barrel may include volume markings to indicate the amount of fluid inside, allowing for accurate measurement.
A plunger is a movable component that fits snugly inside the barrel. The plunger usually has a handle or thumb grip at one end for easy manipulation. When the plunger is pushed or pulled, the plunger creates a vacuum or pressure within the barrel, allowing the fluid to be drawn into the syringe or expelled from the syringe.
The needle is a hollow, pointed metal tube attached to the end of the syringe barrel. A needle can be used to penetrate the skin or other tissues for an injection or withdrawal of fluids. Needles come in various lengths and gauges depending on the specific application. In certain embodiments, a syringe may not include a needle and instead may be coupled to another structure such as a fluid passage.
In certain embodiments, a syringe may include a tip of the syringe where the needle can be attached. Some syringes may come with a removable cap to cover a needle before use. In certain embodiments, a syringe may include a luer lock or luer slip. These are two common types of connections used to attach a needle to the syringe. The luer lock mechanism involves twisting a needle onto the syringe for a secure connection, while the luer slip mechanism involves simply pushing a needle onto the syringe.
A plunger seal or gasket is a rubber or silicone ring located at the base of the plunger. The plunger seal or gasket forms a tight seal against the inner walls of a barrel, preventing leakage of the fluid. Some syringes have a flange, which is a flat, wing-like extension at the base of the barrel. The flange provides stability and support when the syringe is held or manipulated.
