Abstract

A tube set for a blood handling apparatus, in particular an extracorporeal blood handling apparatus with an extracorporeal blood circuit or an apparatus for peritoneal dialysis, and a blood handling apparatus that has such a tube set are described. The tube set includes a device for collecting particles provided in a tube line portion of the tube set downstream of the tube portion placed in the occluding hose pump. The device for collecting particles prevents retention of solid substances that are possibly contained in the dialysis fluid, substituate or peritoneal solution. The tube set also has a device for limiting the pressure in the tube line portion between the occluding hose pump and the device for collecting particles. The device for limiting the positive pressure prevents an excessive positive pressure from building up in the tube line when fluid flow through the device for collecting particles is reduced or interrupted.
