Invention of Syringe
Syringe
In 1650, Pascal invented the syringe and created the hydraulic press, an instrument based upon the principle that became known as Pascal’s law: pressure applied to a confined liquid is transmitted undiminished through the liquid in all directions regardless of the area to which the pressure is applied.
Hypodermic Syringe
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'.
Disposable Syringe
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.
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.
