KnowraSyringeSyringeA device with a plunger and hollow barrel used to draw in, measure, or inject fluids through a nozzle or needle.BriefConnectPiston: A movable component that transmits force by sliding within a cylinder. The syringe plunger acts as a piston, changing barrel volume to draw in or expel fluid.Hypodermic injection: The delivery of a substance beneath the skin using a hollow needle. A syringe and needle form the standard tool for administering many injectable medicines.Graduated cylinder: A tall vessel marked with graduations for measuring liquid volume. It measures liquid without the plunger-driven transfer built into a syringe.Jet injector: A device that forces liquid through a tiny opening at high pressure to penetrate skin without a needle. It delivers injections without the needle used by conventional syringes.Pascal's law: A pressure applied to a confined fluid is transmitted undiminished throughout that fluid. Pressure from the plunger travels through the syringe's fluid to its outlet.Vaccination: The administration of a vaccine to stimulate protective immunity. Syringes commonly deliver injectable vaccines into muscle or other tissue.Syringe calibration: The process of checking whether a syringe delivers the volume indicated by its scale. Calibration connects barrel markings to the actual volume expelled.Needle-free injection: The delivery of medication through skin without a conventional hollow needle. It describes the broader approach used by devices such as jet injectors.Luer taper: A standardized tapered fitting used to connect medical devices that carry fluids. It provides a detachable, often leak-resistant connection between syringe and needle or tubing.Insulin pen: A handheld device that delivers measured doses of insulin, typically through a replaceable needle. It offers an alternative to drawing each insulin dose from a vial with a syringe.Show all 22Linked from 7 pagesBoyle's lawRelated: Pulling its plunger increases chamber volume and lowers pressure, drawing fluid or gas inward.Air pumpCompared with: A syringe can move air manually, but is typically used as a general fluid-handling instrument.Subcutaneous injectionRelated: Syringes are commonly used to measure and administer subcutaneous doses.PipetteCompared with: A syringe can transfer liquid, but its common designs and uses differ from calibrated pipettes.Hypodermic needleRelated: The needle commonly attaches to a syringe, whose plunger drives fluid through its lumen.VialCompared with: A syringe dispenses or transfers liquid; a vial stores it.Show all 7
