Abstract
This invention relates to a method for clearing a wetted hydrophobic filter, in which in a first step the air permeability of the hydrophobic filter is monitored and in which in a second step the hydrophobic filter is cleared by means of a connected air pump, if it is detected that the hydrophobic filter is clogged. Furthermore, the invention relates to an apparatus for performing this method.
Claims10
A method of clearing a wetted hydrophobic filter in an extracorporeal blood circulation with an air separation chamber to which a pressure pick-up and an air pump are connected via a conduit, the hydrophobic filter being disposed in said conduit, comprising the following steps:
- monitoring the air permeability of the hydrophobic filter, and
- clearing the hydrophobic filter by means of the connected air pump, if it is detected that the hydrophobic filter is clogged.
