A Med-E-Jet vaccination gun from 1980. A jet injector, also known as a jet gun injector, air gun, or pneumatic injector, is a medical instrument that uses a high-pressure jet of liquid medication to penetrate the skin and deliver medication under the skin without a needle. Jet injectors can be single-dose or multi-dose.
The species is traditionally known as Meria laricis.Meria was first described by Jean Paul Vuillemin (Vuill.) in France in 1896. [1] DNA analysis in the 1990s indicated its closest ancestor was the Rhabdocline genus, with the similarity significant enough for the genera of Meria, Hartigiella, and Rhabdocline to be combined as synonyms, with Rhabdocline chosen as the name of the merged genus.
Today, pen needles are manufactured at shorter needle lengths than required for typical vial and syringe administration, which decreases the pain associated with injection. [2] They are available in multiple lengths and gauge of needle , including 3.5mm, 4mm, 5mm, and 8mm lengths, and 31 through 34 gauge. [ 8 ]
LONDON — Two years into the COVID-19 pandemic, one would have thought there was enough talk (and experience) of needles, injections, side effects — and all the debate that goes with them. But ...
accelerate the syringe forward, puncturing the injection site; actuate the piston of the syringe, injecting the drug; deploy a shield to cover the needle; Some injectors are triggered by simply pushing the nose ring against the injection site. In these designs, the protective cap is the primary safety.
The microneedles range in size, shape, and function but are all used as an alternative to other delivery methods like the conventional hypodermic needle or other injection apparatus. Stimuli-responsive microneedles are advanced devices that respond to environmental triggers such as temperature, pH, or light to release therapeutic agents.
Autoinjector, a device to ease injection, e.g. by the patient or other untrained personnel. Hippy Sippy; Jet injector, injects without a needle, by squirting the injection fluid so fast that it makes a hole in the skin. Luer taper, a standardized fitting system used for making leak-free connections between syringe tips and needles.
The FAST 1 device consists of multiple needles in a probe that penetrates the manubrium once manual pressure is applied. [16] The Bone Injection Gun (BIG) device is a small, plastic, disposable, spring-loaded device that has a trigger that shoots the IO needle into the IO insertion site, which is more than likely in the proximal tibia.
