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.
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 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 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 fluid can flow through the valve unit, wherein the pump module is formed by a base and a membrane, the first wall section is operable from outside the pump module, and wherein the movable valve body is directly connected to the first wall section.
A pump base module comprising a pump drive system, a receptacle and a valve actuator, wherein the receptacle is configured to removably receive therein 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 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 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 fluid can flow through the valve unit and wherein a valve actuator is configured to deform first wall section of the valve unit of the pump module during or after inserting the pump module into the receptacle so as to cause the valve body to be in the operating position.
A pump system, comprising 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 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 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 fluid can flow through the valve unit, and a pump base module, wherein the pump base module includes a pump drive system, a receptacle and a valve actuator, wherein the receptacle is configured to removably receive therein the pump module, and wherein the valve actuator is configured to deform the first wall section of the valve unit of the pump module during or after inserting the pump module into the receptacle so as to cause the valve body to be in the operating position.
