A hypodermic syringe has the ability to retain liquid and blood in it up to years after the last use and a great deal of caution should be taken to use a new syringe every time. The hypodermic needle also serves an important role in research environments where sterile conditions are required.
A 3-way syringe/nozzle has separate internal channels supplying air, water or a mist created by combining the pressurized air with the waterflow. The syringe tip can be separated from the main body and replaced when necessary. In the UK and Ireland, manually operated hand syringes are used to inject lidocaine into patients' gums.

This double hold is a highly comforting way of holding hands, says Donaldson. “The holder is signaling that they’re fully attentive,” she notes. “They’re there for you, and you can trust ...
This connector attaches to another device: e.g. syringe, vacuum tube holder/hub, or extension tubing from an infusion pump or gravity-fed infusion/transfusion bag/bottle. Newer models include a slide and lock safety device slid over the needle after use, which helps prevent accidental needlestick injury and reuse of used needles, which can ...
