Durchspülen

Durchspülen is a technical term used to describe the process of flushing or rinsing a space, device, or system by passing a liquid through it. The goal is to remove residues, debris, gases, or contaminants and to restore or ensure proper flow and function. The exact meaning and method vary by field, but the core idea is to achieve cleanliness and patency through controlled liquid flow.

In medical settings, Durchspülen commonly refers to flushing a catheter, intravenous line, or diagnostic instrument with a sterile liquid, usually isotonic saline or a designated solution, to prevent occlusion, remove air, or prepare for use. Procedures are guided by device instructions, clinical guidelines, and sterile technique to minimize infection risk and tissue injury. In plumbing and building maintenance, Durchspülen describes flushing pipelines, valves, and distribution lines after installation, repair, or contamination events to clear sediments and ensure uninterrupted supply. In environmental engineering, flushing can apply to groundwater wells or sampling lines to replace stagnant water with representative, fresh samples.

Fluids chosen for Durchspülen depend on the context: sterile or medical-grade solutions for clinical use, clean water or approved cleaners for plumbing, and compatible reagents for laboratory applications. Key considerations include achieving sufficient flow without causing damage, avoidingBackflow or cross-contamination, and adhering to relevant standards and safety rules. Benefits include improved patency, reduced contamination risk, and more reliable measurements or delivery of fluids. Potential risks encompass infection or tissue injury in medical contexts, chemical incompatibilities, pressure-related damage, and contamination if sterility is not maintained.
