Syringe

From WikiMD's Wellness Encyclopedia

(Redirected from Syringes)

Syringe is a simple reciprocating pump consisting of a plunger (though in modern syringes, it's actually a piston) that fits tightly within a cylindrical tube called a barrel. The plunger can be linearly pulled and pushed along the inside of the tube, allowing the syringe to take in and expel liquid or gas through a discharge orifice at the front (open) end of the tube. The open end of the syringe may be fitted with a hypodermic needle, a nozzle, or tubing to help direct the flow into and out of the barrel.

History[edit | edit source]

The word "syringe" is derived from the Greek σύριγξ (syrinx) meaning "tube". The first known use of the word syringe was in the 14th century.

Types[edit | edit source]

There are several types of syringes used for various purposes, including:

Uses[edit | edit source]

Syringes are used for various medical procedures such as injections, infusion pumps, and aspiration. They are also used in non-medical applications such as in inkjet printing and water guns.

Safety[edit | edit source]

The reuse of syringes and needles poses a risk of infection, especially when not properly sterilized. To minimize this risk, many medical professionals use safety syringes which have built-in mechanisms to prevent reuse.
