Catheter

Abstract

Abstract The catheter (10) can be used as a flushing catheter or a slurping probe and consists of a flexible catheter tube (11) with a closed tip (12), whose lumen is divided by an arched dividing wall (22) into a main lumen (20) and a smaller secondary lumen (21). The main lumen (20) communicates with the outer environment via openings (25) in the wall (26) of the catheter tube (11), and a slit (30) in the dividing wall (22) connects the main lumen (20) to the secondary lumen (21). The slit (30) acts as a valve, opening under the pressure of a flushing liquid from the secondary lumen (21), but closing the latter off to prevent penetration of body fluid from the main lumen (20) into the secondary lumen (21). In this way, encrustations of the secondary lumen (21) are prevented, and the latter cannot become blocked. <IMAGE>
