AspirationKatheters

Aspiration catheters are medical devices used to remove fluids or debris from a body cavity or passage. They are typically slender, flexible tubes made of plastic or rubber, designed to be inserted into specific anatomical locations. The primary function of an aspiration catheter is to create suction, thereby drawing out unwanted substances. This can range from blood and pus to secretions or even foreign objects.

The design of aspiration catheters varies depending on their intended use. Some have a simple open end, while others feature a more complex tip with multiple openings or a stylet for added rigidity. The diameter and length are also customized to suit the area being accessed. They are commonly employed in surgical procedures, intensive care settings, and for diagnostic purposes.

Examples of their application include draining abscesses, clearing airways, removing fluid from the pleural space, or obtaining samples for laboratory analysis. The procedure involving an aspiration catheter is usually performed by trained medical professionals. Sterility is paramount to prevent infection. Once the fluid has been removed, the catheter is typically withdrawn and discarded. The use of aspiration catheters is a critical component of various medical interventions aimed at patient recovery and diagnosis.
