The two-part stoma care consists of a stoma bag and a separate skin protection plate. The skin protection plate remains attached to the skin for a longer period of time, while the bags can be connected and removed via a snap ring.
Closed systems are suitable for smaller and solid precipitation quantities. These are mainly used by colestomy carriers, as the excreted stool is firmer in them. Closed bags usually have an activated carbon filter through which all intestinal gases can escape in a neutral odour.
Bags with an outlet opening are called "draining bags" or "open system". Through the drain opening at the lower end of the collection bag, the body excrements collected in the bag are emptied. They are mainly used by ileostomy carriers, as the excreted stool is thinner in them. The bag can thus be emptied without changing the entire supply.
