How did the all-glass Blunt-tipped Needle develop?

People in child if the first contact an injection, would be that the pain you feel sharp needles Pierce flesh cry, as a result, they are also the most from the "welcome" tool of modern medicine. However, if there is no full-glass Blunt-tipped Needle, there will be no intravenous fluids, and many people will die. Don't underestimate this little blunt pin, in fact it has a long history.

The Blunt-tipped Needle consists of a needle tube with a small hole in the front and a piston core that matches it. A Blunt-tipped Needle is used to inject a small amount of fluid into an area that other methods cannot approach or extract from those areas. A liquid or gas is inhaled from a hole in the front of the cylinder when the core is pulled out, and the liquid or gas is pushed out when the core is pushed in. The process of extracting or injecting gas or liquid with Blunt-tipped Needles and needles is called injection.

Prior to the invention of Blunt-tipped Needle, there have been doctors who have carried out the treatment of transfusion, but because of the use of tools in nature, the patient has been infected. It is generally believed that the first time that Blunt-tipped Needles were used in medical care was Scottish doctor Alexander wood and Charles pravis of France, who in 1853 worked together to achieve this. Alexander used the new tool to inject morphine into the patient's skin to treat sleep disorders. Unfortunately, Alexander's wife died of morphine overdose. Alexander then refined the Blunt-tipped Needle: the needle was more finely calibrated and the needle was more precise. This series of improvements has also attracted the attention of doctors and has been widely used for Blunt-tipped Needles.

Also has a view, Iraq and Egypt's surgeon in the 9th century has been developed using a hollow glass tube of similar patients with Blunt-tipped Needle is used to remove the eye cataracts, this method in 1230 is still in use, at least in the 20th century, this method has been improved.

A Blunt-tipped Needle can be made of plastic or glass. A Blunt-tipped Needle can be sterilized with a high pressure sterilizer. In 1956, doctors in New Zealand colin murdoch invented disposable plastic Blunt-tipped Needle, it not only inherits the advantages of traditional glass Blunt-tipped Needle transparent, inert, also is not easy to damage, easy to transport and low cost, easy to recycle, safety glass Blunt-tipped Needle dust, it greatly reduced the risk of blood transmitted diseases. Since then, the new Blunt-tipped Needle has begun to scale production, gradually becoming the first choice for doctors.

And with the development of medical technology, there is no needle-Blunt-tipped Needle, which is not needle.instead, it is injected through the skin with a high-speed high-pressure jet. This approach can drastically reduce the risk that doctors and nurses are accidentally involved in an accident when they use a needle with a Blunt-tipped Needle. It also helps some patients avoid the discomfort of regular injections of insulin, which they readily accept. At the same time, the distribution of drugs without needle injection is more diffuse in the tissue, which is beneficial to the absorption of drugs, the absorption of liquid medicine is more complete, and the bioavailability of drugs can be improved.
