Needle-Free Smallpox Vaccine Injector that is Easy for Anyone
to Use Developed by PenJet® Corporation
Santa Monica, CA, December
13 – A disposable, needle-free injector for smallpox vaccines,
that is safe and simple enough for most people to instantly administer
an inoculation to themselves or others, has been developed by PenJet®
Corporation. Up until this time, a smallpox vaccination required a highly
trained professional giving multiple needle injections for each inoculation.
The new injector, called
a PenJet®, is about the size of a lipstick. It uses self-contained,
compressed inert gas to inject drugs into the skin surface without a
needle. Because it is needle-free, the recipient experiences minimal
sensation and hears little noise when the injection is given. By injecting
simultaneously through four orifices it instantly gives a complete intradermal
To administer a needle-free
vaccination, a protective cap and safety ring that avoids accidental
triggering is removed, the nozzle is placed against a suitable injection
site, such as the upper arm, and the PenJet® administers the injection
when gently pressed. After use, the PenJet® can be safely discarded
in any trash receptacle, eliminating the need for special sharps containers,
since it has no needle and has injected all the vaccine it contained.
PenJets® will be
shipped from a pharmaceutical company, pre-filled with a vaccine or
drug ready to inject. Low cost and ease of use make it applicable for
rapid mass inoculations of entire populations for diseases such as smallpox
and influenza, to home administration of pharmaceuticals by patients
or their caregivers.
A wide range of intradermal,
subcutaneous and some intramuscular injections can be administered by
PenJets®. In addition to liquid medications and vaccines, PenJets®
can store, mix and administer needle-less injections of freeze-dried
(lyophilized) drugs. These are the latest, highly potent, biotechnologically
derived proteins that require lyophilization to maintain shelf life.
PenJets® are covered
by 12 U.S. patents with many more pending in the U.S. and around the
world. PenJet® Corporation is a private company specializing in
