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. |

1. Lid apparatus for a medical device for extracorporeal blood treatment, comprising:
a lid hinged by means of at least one pivot joint at the medical device, wherein the pivot joint comprises a first joint section and a second joint section, wherein said joint sections are pivotable with respect to each other about an axis of rotation 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 a relative distance between the axis of rotation and the medical device in the first position and the second position is different; wherein said joint sections are releasably lockable in at least one of the first position or the second position, wherein the lid apparatus comprises at least one pair of contact surfaces having a first contact surface and a second contact surface which, perpendicular to the axis of rotation, are resiliently biased against each other, wherein the first contact surface comprises a rolling and latching geometry resiliently biased against the second contact surface 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; and wherein the first contact surface comprises a flat portion having a first edge and a second edge, a first curved portion adjacent the first edge, and a second curved portion adjacent the second edge, and wherein the axis of rotation is closer to the second contact surface when at least one of the first or second curved portion is in contact with the second contact surface than when the flat portion is in contact with the second contact surface. |
