Needle Dwayne

A Doyen's needle is a needle that is used in medicine to inject drugs into the human body. It was developed by French physician Louis-Albert Doyen in 1849 and was one of the first medical needles.

Doyen's needle is shaped like a cone with a pointed end and a flat base. It is made of stainless steel and has a length of about 20-30 cm and a diameter of 0.6-1.2 mm. The Doyen's needle is used to inject various medications such as antibiotics, hormones, vitamins and other medications.

The Doyen's needle is inserted through the patient's skin at an angle of 90 degrees. This reduces the risk of tissue damage and reduces pain during injection. After inserting a needle into the skin, the doctor slowly injects the drug into the patient's body.

Even though the Doyen's needle is one of the oldest medical needles, it is still widely used in medical practice. This is due to its ease of use, safety and effectiveness.
