NEEDLE
FREE INJECTION

|
|
The INJEX™ jet injector is an alternative to
needle syringes and offers a nearly painless, safe and cost
effective INJEXION™ in a broad range of applications.
| The
INJEXION™ is an injection without a needle
The concept
of needle-free injection (= INJEXION™) eliminates
widespread fear of injection-related pain among patients
and at the same time eliminates the risks of transmitting
infectious diseases like Hepatitis and HIV by contaminated
needle stick accidents. In the US, about one million
needle injuries are reported every year associated with
considerable expenditures for replacing and treating
infected persons.
Previous attempts at making needle-free jet injectors
acceptable to the public failed due to high cost, awkward
design and difficulty of use.
|
|
|
INJEX™
has overcome these issues successfully and significantly
facilitates frequent administration of subcutaneous
injections. This new-generation jet injector offers a safe
and nearly painless mode of application, thus considerably
enhancing compliance of chronic patients. By adopting
these innovative technique, health care professionals can
completely change the present concept of drug injection.

Development
and
Production of INJEX™ |
The
INJEX™ was developed and made
available to the European market by
RÖSCH AG Medizintechnik i.G..
Several patents have been issued for the
INJEX™-system. INJEX™ has market
clearance from the FDA in the USA and
received European CE-approval (CE 0482)
for pharmaceuticals suitable for
subcutaneous jet-injection. |

How
does INJEX™ work?
Jet
injection propels a fine stream of
liquid medication under high pressure
through a small orifice through the
skin. All without a needle. INJEX™ is
a spring-loaded needle-less hypodermic
injection system.
A Reset Box will cock the integrated
spring before each use. Sterile adapters
enable the transfer of the desired
medication from its vial into the
disposable ampule for injection. A
reusable transporter is available to
draw up liquid drugs from cartridges (e.g.LA).
Once the required amount of medication
has been transferred into the ampule, it
is attached to the injector.
A
reusable transporter is available to
draw up liquid drugs from cartridges
(e.g. Local anaesthetic). Once the
required amount of medication has been
transferred into the ampule, it is
attached to the injector. The injector
is placed perpendicular to the
desinfected injection site
The
INJEXION is released by pressing the
trigger. The high velocity jet
stream pierces the skin and the drug
disperses into the subcutaneous adipose
tissue.The injection is accomplished,
the ampule is removed and discarded
without special handling procedures
associated with high disposal costs.
