Level monitoring of critical fill levels using magnetism in medical urine and colostomy bags, as well as similar bags for collecting fluids and excretions, which are directly or indirectly connected to the patient during use.

Abstract

Level monitoring of critical fill levels in medical urine bags, characterized in that a magnetic field, in conjunction with a spring force and a force opposing the spring force due to urine accumulation in a flexible bag, triggers an electrically generated acoustic and optical warning signal.
