In the UK, the syringe was developed, which allow the injections virtually painless. According to the BBC, the author was developing 29-year-old specialist in the field of industrial design, Oliver Blackwell (Oliver Blackwell).
The new device resembles a catheter for intravenous infusion. In addition to the usual needle through which the injected under the skin of a particular drug at the end of the syringe, there is still a fine needle. She was the first pierces the skin, and place it in the subsequent injection of a small quantity (about 0.2 milliliters) pain.
Accordingly, the penetration of the needle under the skin of the main, which follows the first one takes place under local anesthesia.
