A syringe is a simple reciprocating pump consisting of a plunger (though in modern syringes, it is 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 ...
The needle on a safety syringe can be detachable or permanently attached. On some models, a sheath is placed over the needle, whereas in others the needle retracts into the barrel. Safety needles [1] serve the same functions as safety syringes, but the protective mechanism is a part of the needle rather than the syringe. Legislation requiring ...
A syringe with a male luer lock fitting, and a needle with female luer lock fitting (purple) which screws into it. The Luer taper is a standardized system of small-scale fluid fittings used for making leak-free connections between a male-taper fitting and its mating female part on medical and laboratory instruments, including hypodermic syringe tips and needles or stopcocks and needles.

A hypodermic needle (from Greek ὑπο- (hypo-= under), and δέρμα (derma = skin)) is a very thin, hollow tube with one sharp tip. It is one of a category of medical tools which enter the skin, called sharps. [1]
It is designed with a luer-lock device to accept a sterile hypodermic needle or to be linked directly to intravenous tubing line. The product can deliver an intravenous or intramuscular injection by means of a holder which attaches to the barrel and plunger to the barrel plug. Medication is prefilled into the syringe barrel.
A socket wrench (or socket spanner) is a type of spanner (or wrench [1] in North American English) that uses a closed socket format, rather than a typical open wrench/spanner to turn a fastener, typically in the form of a nut or bolt. [2] The most prevalent form is the ratcheting socket wrench, often informally called a ratchet.

The term "high dead space" refers to the fluid remaining within the needle and between the syringe hub and the plunger. This space can be as high as 84 micro liters in conventional syringes. [2] Conventional high dead space syringes have existed since the mass production of plastic syringes with removable needles in 1961. [3]
