Syringes are a common medical tool. As early as the 15th century, the Italian Catinel proposed the principle of syringe. It is mainly used to extract or inject gases or liquids with a needle.
Syringes can also be used for medical devices, containers, such as some chromatography in the scientific instruments injected through a rubber diaphragm.
The emergence of needleless syringes was an epoch-making revolution in medical devices. The emergence of syringes is an epoch-making revolution in the field of medical devices and the process of extracting or injecting gases or liquids with a needle is called injection.
The syringe consists of a barrel with a small hole in the front and a matching piston mandrel, which is used to inject small amounts of liquid or gas into or withdraw it from areas that are inaccessible by other means. The liquid or gas is drawn in through the hole in the front of the barrel when the mandrel is withdrawn, and is squeezed out when the mandrel is pushed in.
According to medical history books, the first form in which the syringe appeared was the enema. China's Han Dynasty physician Zhang Zhongjing in his "Treatise on Typhoid Fever" (written in 219 A.D.), "Yangming full chapter" wrote: "Yangming disease, since the sweating, if sweating, urination self-liberation, this is the fluid within the exhaustion of the hard can not be attacked, when it is necessary to want to stool, it is desirable to honey decoction guide and through the. If the root of the earth melon and the bile of the pig, can be a guide."
In the book's "pig bile formula" in the article and clearly stated: "a large pig bile, diarrhea and a little vinegar, in order to instill the Valley Road (anus), such as a food hectare, when the stool, out of the pasty food and evil things very effective." How to "fill the valley road"?
He wrote: "with a small bamboo tube ...... into the Valley Road." This small bamboo tube is the prototype of an enema - a syringe.
