Who invented the syringe with a needle and what year

The English physician began to develop vaccines by studying the link between smallpox and cowpox, a milder disease. He injected one boy with cowpox and found that the boy became immune to smallpox. Jenner published his findings in Within three years, as many as , people in Britain had been vaccinated against smallpox.

The microneedle is a painless alternative to the needle and syringe. A chemical engineering professor from the Georgia Institute of Technology named Mark Prausnitz teamed up with electrical engineer Mark Allen to develop the prototype microneedle device.

It is made up of silicon-based microscopic needles — each the width of a human hair — and looks something like the nicotine patch used to help people quit smoking. Its 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 control the time and dosage of the medicine delivered. Another delivery device is the Hypospray.

Developed by PowderJect Pharmaceuticals in Fremont, California, the technology uses pressurized helium to spray dry powdered medications on the skin for absorption. Actively scan device characteristics for identification.

They can be used in certain forms of cooking to inject liquids into certain foods. They are also commonly used to refill ink cartridges for printers, inject glue or lubricants into hard-to-reach places, for precision measurement when mixing liquids, and even to feed small animals when they are being hand-reared.

Indeed, there are few medical tools so commonplace, and yet so indispensable, as the plastic disposable syringe. Log in Remember me. Lost your password? The Right Superfoods for Kids. Need Help? Chat with us. Start a Conversation.

However, these early injections were not successful and injections did not come into fashion again until the latter part of the s. The hollow metal needle was invented in by Irish physician Francis Rynd. The first devices recognizable as hypodermic syringes were independently invented virtually simultaneously in by Scottish physician Alexander Wood and French surgeon Charles Gabriel Pravaz.

The evolution of the syringe and its needle continues with the introduction of transdermal drug delivery by micron-scale needles and monitored drug delivery.
