Abstract
A module, a base module and a system which comprises a module and a base module includes a pump channel and a valve unit which is connected with the pump channel wherein a fluid can be pumped through the pump channel and the valve unit, wherein a first wall section of the valve unit is flexible. The pump module has a movable valve body arranged in the valve unit, wherein the valve body can occupy an idle position in which the valve body closes the valve unit to prevent fluid from passing through. The valve body can occupy an operating position in which the valve body allows the fluid to flow through the valve unit and in which the valve body can be put in operating position through a deformation of the first wall section of the valve bodies so that the fluid can flow through the valve unit.
Claims18
A pump module for a medical wobble pump, said pump module comprising a pump channel, and a valve unit connected to the pump channel, the valve unit having a flexible first wall section, wherein a fluid can be pumped through the pump channel and the valve unit, a movable valve body arranged in the valve unit, wherein the movable valve body transitions between an idle position, in which the movable valve body closes the valve unit to prevent fluid from passing through, and an operating position, in which the movable valve body allows the fluid to flow through the valve unit and wherein the movable valve body is configured to transition into the operating position through a deformation of the first wall section so that the fluid can flow through the valve unit, wherein the valve unit further comprises a flexibly deformable second wall section that resiliently pre-tensions the valve body against a stop position and a pump body having a hollow space that forms the valve unit, wherein a wall section of the hollow space includes the first flexible wall section, and a further wall section of the hollow space includes the second flexible wall section, wherein the first wall section is formed by molding a flexible material to the pump body.
