A medical instrument made of a tube with a plunger which either slides down inside the tube, forcing the contents out through a needle as in an injection, or slides up the tube, allowing a liquid to be sucked into it.
Device for withdrawing, injecting, or instilling a fluid. It usually includes a glass or plastic barrel with a close fitting plunger at one end and a needle at the other end.
A medical instrument used to inject fluids into the body or to remove fluids from it. A syringe is a small hand pump, consisting of a small cylindrical barrel and piston or a barrel and a soft rubber bulb. Many types of syringes are available, including hypodermic syringes, which usually have a narrow barrel and end in a hollow, small-bore needle. Syringes are used to inject drugs into the tissues. Dentists use water syringes designed to permit controlled sprays of water into specific areas of the mouth. Syringes that have rubber bulbs are used to create a vacuum for the gentle suction of small amounts of body fluids, such as nasal or oral secretions.
An instrument consisting of a piston in a tight-fitting tube that is attached to a hollow needle or thin tube. A syringe is used to give injections, remove material from a part of the body, or to wash out a cavity, such as the outer ear.
An instrument for injecting fluid into, or withdrawing fluid from, a body cavity, tissue or blood. The basic design is of a calibrated barrel with a plunger at one end and a nozzle to which a hollow needle can be attached at the other end. Most syringes are disposable, plastic, presterilised and packed in sealed containers. Injections can be given under the skin, into muscle, into a vein or into the cerebrospinal fluid. The term hypodermic, though literally meaning under the skin, is now used to describe most syringes.
A tubular device often paired with a needle for the purpose of injecting liquid into, or drawing liquid out of, a body cavity, blood vessel, or tissue.
