Zeiss loop catheter

**Zeiss Loop Catheter**

Loop catheters are used to administer medications, fluids, and flush deep tissues and serous cavities. Loop catheters are also used to access cavities where a higher profile catheter is needed, such as large joints or the urethra. The loop technique involves creating a loop from which liquid or medicinal substances flow, thus creating a kind of stream. This technique can be used to reach a portion of the depth where other insertion techniques, such as those based on the Kandler method, are not available.

The loop method is a technique for creating a hole in the skin. By spreading the skin, the infiltrated fluid is absorbed through the loop between the skin and the catheter. This method can achieve any depth of penetration without damaging soft tissue or neurovascular structures.

Each catheter contains additional diameters and lengths that can be changed until the catheter passes through the cavity wall properly. Catheters are adapted in size for cavities that have a certain shape and volume. In some cases, catheters of different sizes can be changed depending on the length or location of the area to be treated, or the subsequent introduction of other mechanisms.

Catheters range in length from 45 to 90 centimeters, with the most common sizes being close to 60 and 75 centimeters. The size of the catheter is chosen so that after treatment the catheter is removed from the body, leaving the smallest part - the open end. If the entire catheter is removed first, the procedure may need to be repeated, making it more difficult.

The use of Loop Zechs catheters is a painful procedure because the intracavitary space is not large enough to increase the distance from the skin surface relative to the skin and provide sufficient buoyant force along the path of catheter advancement. This means that after the first attempt, the catheter may rest against soft tissue, and further movement is impossible. Therefore, one should not go too close to the skin surface, nor should one use a catheter diameter that is too large or an advance speed that is too fast during insertion. Therefore, therapists insert loop catheters under anesthesia, usually
