How to make a simple syringe

Can't do it

Invention and use

As early as the 15th century, the Italian Catinel proposed the principle of the syringe. But it wasn't until 1657 that the Englishmen Boyle and Raine conducted the first human trials. Abel, a surgeon in the army of King Louis XVI of France (reigned 1774-1792), also envisioned a piston syringe. But it is generally recognized that Pravoz of France was the inventor of the syringe. The syringe he supervised in 1853 was made of silver, had a capacity of only 1 milliliter, and had a threaded piston rod.

Ferguson, an Englishman, was the first to use glass syringes. The transparency of glass was good, so you could see the injected drug. Since then there are glass tube metal and made of syringes, can be sterilized by boiling, the needle can also be sharpened and reused and sterilized. Syringes made of plastic, used once that is thrown away, greatly reducing the risk of infection during injection. In order to ensure hygiene and prevent cross-infection, most contemporary syringes are made of plastic.

Use

Syringes can also be used for medical devices, containers, and scientific instruments such as those used in some chromatography to inject through a rubber diaphragm. Injecting gas into a blood vessel will result in an air embolism. Air is removed from the syringe to avoid embolization by inverting the syringe, tapping it gently, and squeezing out a little liquid before injecting into the bloodstream.

In settings where precision is not the primary concern for germs, such as in quantitative chemical analysis, glass syringes are still used because of their small error margins and smooth pushrod movement.

Syringes can also be used to inject some juices into meat when cooking to improve flavor and texture, or into pastries when baking. Syringes can also be used to fill cartridges with ink.
