Hypodermic
Needle - Syringe Needle
Forms of intravenous injection and
infusion began as early as 1670. However, Charles Gabriel Pravaz and Alexander
Wood were the first to develop a syringe with a needle fine enough to pierce
the skin in 1853.
Extract from:
"Blood and Blood Transfusions"
By Major R. Ellison, Surgeon
33rd Regiment, 1st Brigade Virginia Vol.
Many
of the technical difficulties which had faced those experimenting with
blood transfusion were removed after 1853 by the invention of the hypodermic
syringe, with its hollow pointed needle. Credit for the evolution of this
universally useful appliance is usually given to Doctor Alexander Wood
(born 1817), who was appointed Secretary of the Royal College of Physicians
of Edinburgh in 1850. For some time, Doctor Wood had been experimenting
with a hollow needle for the administration of drugs. Eventually, he felt
confident enough to publish in "The Edinburgh Medical and Surgical Review"
a short paper - 'A New Method of treating Neuralgia by the direct application
of Opiates to the Painful Points' - in which he showed that the method
was not necessarily limited to the administration of opiates. At about
the same time, Charles Gabriel Pravaz of Lyon was making a similar syringe
which quickly came into use in many surgeries under the name of 'The Pravaz
Syringe'.
According to MedhelpNet.com:
"Charles Gabriel Pravaz (1791-1853),
French surgeon, and Alexander Wood (1817-1884), Scottish physician, independently
invented the hypodermic syringe. It is first used to inject morphine as
a painkiller."
Vaccination Syringes
Benjamin A. Rubin invented the "Pronged
Vaccinating and Testing Needle" or vaccination
needle. This was a refinement to the conventional syringe needle. Disposable Syringes
Arthur E. Smith received 8 U.S. patents for a disposable syringe
from 1949-50. (U.S. Patent nos. 2524363, 2524362, 2497562, 2490553, 2490552, 2490551, 2478845,
2478844) In 1954, Becton, Dickinson and Company
created the first mass-produced disposable syringe and needle, produced in
glass. It was developed for Dr. Jonas Salk's mass administration of one million American children with the new Salk polio
vaccine. In 1955, Roehr Products introduced a plastic
disposable hypodermic syringe called the Monoject. In 1956,
Colin Murdoch, a pharmacist
from Timaru, New Zealand patented a plastic, disposable syringe to replace
the glass syringe. Colin Murdoch has patented forty-six
inventions including: a silent burglar alarm, automatic syringes for vaccinating
animals, the childproof bottle top, and the tranquilizer gun which he invented
in 1959. Colin
Murdoch - Biography In 1961, Becton Dickinson introduced its first plastic
disposable syringe called the Plastipak.
African American inventor Phil Brooks
received a US patent for a "Disposable Syringe"
on April 9, 1974.
Microneedle
The microneedle device is a painless
alternative to the needle and syringe. Mark Prausnitz, a chemical engineering
professor from the Georgia Institute of Technology teamed together
with electrical engineer Mark Allen to develop the prototype microneedle
device, which looks like the nicotine quit smoking patch. The microneedle
is made up of 400 silicon-based microscopic needles, each the width of
a human hair. The tiny, hollow needles are so small, that any medication
can be delivered through the skin without reaching the nerve cells that
create pain. Microelectronics within the device would control the time
and dosage of the medicine delivered.
Hypospray
PowderJect Pharmaceuticals of Fremont,
Calif., created the hypospray a device that uses pressurized helium to
spray dry powdered medicines on the skin for absorption.
