Abstract
A filter for medical fluids comprises a hydrophilic membrane ( ) dividing the filter into an inlet chamber ( ) and an outlet chamber ( ). This prevents air from penetrating the outlet chamber ( ). The air retained in the inlet chamber ( ) is discharged through vent holes ( ). Each vent hole ( ) is covered with a hydrophobic membrane ( ). According to the invention one of the vent holes ( ) is provided in a front wall ( ) opposite the hydrophilic membrane ( ). The other vent hole ( ) is provided in a rear wall ( ) located opposite the front wall ( ) so that the two vent holes ( ) point in opposite directions. Owing to this arrangement of the two vent holes ( ) one vent hole ( ) points upwards irrespective of the filter position. This improves venting of the inlet chamber ( ).
