Abstract
In a filter for filtering human blood, especially in an extracorporeal circulatory system, with a blood inlet, a blood outlet and a vertically directed, hollow, cylindrical filter element located between them and consisting of a filter, and in which the hollow, cylindrical filter element seals housing chambers located in the filter housing between the blood inlet and the blood outlet in such a manner from each other by means of its front surfaces that the blood can only flow through the filter element, whereby the blood inlet is located in the center of the housing and of the hollow, cylindrical filter element and a gas outlet is located at the highest point of the housing, the blood inlet runs axially through the hollow cylinder of the filter element as a central ascending tube and divides it cross section into a smaller ascending pipe section and into a settling chamber section for the blood which is several times larger. The settling chamber section empties in its extended axis into a cylindrical gas separation chamber which comprises a closable gas outlet. The blood outlet is provided in the area of the lowest active filter surface of the filter element as a horizontally projec…
