A Syringe is an instrument (as for the injection of medicine or the withdrawal of bodily fluids) that consists of a hollow barrel fitted with a plunger and a hollow needle. The first piston syringes were used in Roman times. In the 9th century AD: The Iraqi/Egyptian surgeon Ammar ibn 'Ali al-Mawsili' created a syringe using a hypodermic needle, a hollow glass tube, and suction to remove cataracts from patients' eyes, a practice that remained in use up until at least the 13th century. In 1844: Irish physician Francis Rynd invented the hollow needle and used it to make the first recorded subcutaneous (under the skin) injections, specifically a sedative to treat neuralgia. Trypanophobia, the fear of injections and hypodermic needles it is estimated to afflict up to 10% of adults.
