WATER ANALYZER COMPRISING A PNEUMATICALLY DRIVEN MULTI-CHAMBER PERISTALTIC PUMP |
摘要 |
A water analysis device with a pneumatically actuated multi-chamber peristaltic pump includes a base plate comprising a plurality of proximally open pump chambers disposed on a proximal side of the base plate. A pump membrane disposed on the proximal side of the base plate is configured to close the pump chambers. A cover plate is disposed on the pump membrane comprising a respective pneumatic actuator channel in a region of each of the pump chambers. The pneumatic actuator channel is configured to connect to an overpressure source which actuates the pump membrane. A connection channel formed as a groove on a distal side of the base plate is disposed between two of the pump chambers. A separate groove cover is disposed on the distal side of the base plate in a region of the groove. The separate groove cover closes a distal opening side of the groove. |
