Lid apparatus for the pivotable support of a lid on a medical device for extracorporeal blood treatment; medical device for extracorporeal blood treatment with lid apparatus

摘要

A lid apparatus for a medical device for extracorporeal blood treatment that includes a lid which is hinged by means of at least one pivot joint at the medical device is disclosed. The pivot joint includes thereby a first joint section which may be positioned at the lid, and a second joint section which may be connectable to the medical device, wherein the joint sections are pivotable about a pivot axis at least between a first position, in which the lid is open, and a second position, in which the lid covers at least a part of the medical device, wherein also the joint sections are latchable in at least one pivoting position. The lid apparatus includes at least one pair of contact surfaces which are perpendicular to the axis of rotation and resiliently biased against each other, wherein at least one of the contact surfaces includes a rolling and latching geometry which is configured such that the lid latches in the second position and the pivoting moveability of the pivot joint is only released when the resilient biasing force is overcome. A medical device for extracorporeal blood treatment including a peristaltic pump and such a lid apparatus is also disclosed.
