An Aspiration or Long Needle is designed for the precise withdrawal or administration of fluids during medical and veterinary procedures. It is commonly used to aspirate fluids such as pus, blood, or other secretions, as well as to deliver medications into deeper tissues or body cavities.

Its extended length allows access to hard-to-reach areas with accuracy and control, making it an essential tool in diagnostic and therapeutic procedures. It supports safe fluid handling, improves procedural efficiency, and ensures minimal tissue trauma when used correctly.
