  2. Syringe - Wikipedia

    en.wikipedia.org/wiki/Syringe

    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 ...

  3. Hypodermic needle - Wikipedia

    en.wikipedia.org/wiki/Hypodermic_needle

    The widespread immunization against polio during the period required the development of a fully disposable syringe system. [14] The 1950s also saw the rise and recognition of cross-contamination from used needles. This led to the development of the first fully disposable plastic syringe by New Zealand pharmacist Colin Murdoch in 1956. [15]

  4. Winged infusion set - Wikipedia

    en.wikipedia.org/wiki/Winged_infusion_set

    The needle is generally inserted toward the vein at a shallow angle, made possible by the set's design. When the needle enters the vein, venous blood pressure generally forces a small amount of blood into the set's transparent tubing providing a visual sign, called the "flash" or "flashback", that lets the practitioner know that the needle is ...

  5. Safety syringe - Wikipedia

    en.wikipedia.org/wiki/Safety_syringe

    Auto Disable (AD) syringes are designed as a single use syringe, with an internal mechanism blocking the barrel once depressed so it cannot be depressed again. The other type of syringe with a re-use prevention feature is the breaking plunger syringe. An internal mechanism cracks the syringe when the plunger is fully depressed to prevent ...

  6. Jet injector - Wikipedia

    en.wikipedia.org/wiki/Jet_injector

    Researchers developed a new jet injection design by combining the drug reservoir, plunger and nozzle into a single-use disposable cartridge. The cartridge is placed onto the tip of the jet injector and, when activated, a rod pushes the plunger forward. This device is known as a disposable-cartridge jet injector (DCJI). [2]

  7. Infusion pump - Wikipedia

    en.wikipedia.org/wiki/Infusion_pump

    Small-volume pumps usually use a computer-controlled motor turning a screw that pushes the plunger on a syringe. The classic medical improvisation for an infusion pump is to place a blood pressure cuff around a bag of fluid. The battlefield equivalent is to place the bag under the patient. The pressure on the bag sets the infusion pressure.
