Ruiskutusvälineen

Ruiskutusvälineen, often translated as injection device or syringe, refers to a tool used to introduce a substance into a cavity or to withdraw fluid from a cavity. The most common form consists of a hollow cylinder with a plunger that can be moved back and forth. At one end, there is typically a nozzle or a luer lock fitting to attach a needle or tubing. The plunger creates suction when pulled back, drawing liquid into the cylinder, and expels the liquid when pushed forward.

Ruiskutusvälineet are widely used in medicine for administering medications, vaccines, and drawing blood samples. They are also employed in laboratories for precise liquid handling and in various industrial applications. The materials used for construction vary, with glass and plastic being common for the cylinder, and rubber or plastic for the plunger tip. Disposable plastic syringes have become prevalent in healthcare settings to prevent disease transmission.

Beyond simple syringes, the term can encompass more complex devices. These might include automatic injectors, pen injectors for specific medications like insulin, or specialized equipment for industrial spraying or lubrication. The fundamental principle, however, remains the controlled delivery or withdrawal of fluids through a contained volume manipulated by a movable piston. The design and specific features of a ruiskutusvälineen are tailored to its intended purpose, influencing factors like volume capacity, needle gauge, and material compatibility.
