Fluid module for a peristaltic pump comprises a one-piece base element having a recess containing a fluid and fluid passages, a membrane element adjoining the recess

摘要

Fluid module comprises a one-piece base element (10a) having a recess (30, 32, 34) containing a fluid and a first and a second fluid passage (38, 40) fluidically connected to the recess, and a membrane element (20a) connected to the base element and adjoining the recess. Fluid adapters (42, 44, 46, 48) formed in one piece with the base element have devices for mechanically holding external fluid lines on the base element to create a fluid connection between the fluid lines and the first and the second fluid passages. A trench provided in the base element surrounds the recess. Preferred Features: At least one fluid adapter has a section protruding from the base element through which the first or second fluid passage extends. The base element is made by a plastic injection molding method or by precise mechanical machining. The membrane element is made of metal foil, ceramic, plastic or silicon.
