The invention and use of syringes

Many people are interested in the invention and use of the syringe, and occasionally see a similar article today, to share with you:

As early as the 15th century, the Italian Cartier made the principle of syringe. But it was not until 1657 that the British Boyle and Rennes had their first human test. French King Louis XVI (1774-1752 reign) Army surgeon Abel has also envisioned a piston syringe. But generally believed that the French Pravorz is the inventor of the syringe. He produced in 1853 the syringe is made of silver, the capacity of only 1 ml, and a threaded piston rod.

British Ferguson first used a glass syringe. Glass transparency is good, you can see the situation of injecting drugs. Since then there are glass tube metal and made with the syringe, can be sterilized by boiling, the needle can also be sharpened and disinfected. The syringes now used are made of plastic and are thrown away once, greatly reducing the risk of infection at the time of injection. In order to ensure hygiene, to prevent cross-infection, contemporary syringes use plastic texture.

Syringes can also be used for medical equipment, containers, such as some of the scientific instruments in the chromatography through the rubber diaphragm injection. The injection of gas into the blood vessels will cause air embolism. Remove the air from the syringe to avoid embolization by inverting the syringe, tapping lightly, and then squeezing a little liquid before injecting it into the bloodstream.

In the case of some precision, rather than the primary consideration of the pathogen, such as quantitative chemical analysis, due to the smaller error of the glass syringe, the push rod moves smoothly so that it is still in use.

You can also inject some juice into the meat with a syringe to improve the taste and texture when you are cooking meat, or into the pastry when baked. The syringe can also add ink to the cartridge.
