What is a needle free injector?
Needle free injection technology (NFIT)is an extremely broad concept which include a wide range of drug delivery systems that drive drugs through the skin using any of the forces as Lorentz, Shock waves, pressure by gas or electrophoresis which propels the drug through the skin, virtually nullifying the use of …
Can you inject without a needle?
MIT researchers have engineered a device that delivers a tiny, high-pressure jet of medicine through the skin without the use of a hypodermic needle. The device can be programmed to deliver a range of doses to various depths — an improvement over similar jet-injection systems that are now commercially available.
What is a needle free device?
Device Description Needle-free injectors are handheld devices or “pens” that use high pressure to force substances, such as fillers, into the body. The substances loaded in the pens are typically sold separately.
Is needleless injection painful?
Driven by the power of a spring in the injector, the medication is pushed through the epidermis into the subcutaneous tissue. The treatment is pain-free and does not damage the skin as the needle does.
How do needle free insulin devices work?
How does it work? The InsuJet™ operation principle is based on pressure. By means of a spring system, the insulin is pressed at high speed through a small orifice in the nozzle, creating a fine stream of insulin that easily penetrates the skin. Directly under the skin the insulin diffuses in the subcutaneous tissue.
How do Hyposprays work?
A hypospray (colloquially, hypo) was a medical device used to inject liquids into the body. The system used a noninvasive transport mechanism of compressed air to transfer the injectant from the device into the subdermal layer below the skin of the body, or artery.
Why do drug users lick needles?
Some of the reasons reported for needle licking include ritualistic practices, cleaning the needle, enjoying the taste of the drug, checking the quality of the drug and checking that the needle was in a usable condition [15] .
Can you get hepatitis from reusing your own needles?
People who inject drugs can get Hepatitis C from: Needles & Syringes. Sharing or reusing needles and syringes increases the chance of spreading the Hepatitis C virus. Syringes with detachable needles increase this risk even more because they can retain more blood after they are used than syringes with fixed-needles.
Who invented needle free injection?
The first to create a “needle-free injector” was the American anesthetist Robert A. Hingson, 65 year ago. Since that time those devices underwent a changeful history.
Why don’t we use jet injectors?
The World Health Organization no longer recommends jet injectors for vaccination due to risks of disease transmission. Numerous studies have found cross-infection of diseases from jet injections.

Are Hyposprays possible?
Hyposprays are definitely possible in the future, but their widespread use may not be. They are expensive and the risk of inadvertently transmitting diseases severely limits multiple uses. However, this does not mean that hyposprays aren’t safe.
