This spring and the associated mechanical components form a one-shot linear actuator. [citation needed] When triggered the actuator drives a three-step sequence: [citation needed] accelerate the syringe forward, puncturing the injection site; actuate the piston of the syringe, injecting the drug; deploy a shield to cover the needle

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]

Injector pens remove some of the complications of syringes by allowing the pen to be "pushed" against the skin at a 90-degree angle (removing the need to inject at a proper angle as is the case with syringes), as well as by replacing a long, thin plunger of a syringe with a simple button which is depressed and held to inject the dose.

One common system has a purpose-designed plastic "pressure bottle" pressurized with a large disposable plastic syringe. A combined flow restrictor, air filter and drip chamber helps a nurse set the flow. The parts are reusable, mass-produced sterile plastic, and can be produced by the same machines that make plastic soft-drink bottles and caps ...
Like a ground glass stopcock, the two parts of a gas syringe should preferably not be interchanged with another gas syringe of the same volume, unless told otherwise by the distributor. [3] Gas syringes come in various sizes from 500 ml to 0.25 ml and tend to be accurate to between 0.01 and 1 ml, depending on the size of the syringe. [4]
Sterilization of an inoculation needle via alcohol burner. The inoculation needle is sterilized using the aseptic technique. [1] [2] [3] [7] An open flame from an incinerator, a bunsen burner, or an alcohol burner is used to flame along the tip and the length of the needle that is to be in contact with the inoculum (or the propagule).
