Disposable cassette

Abstract

The invention relates to a disposable cassette, preferably for use in analysis technology, consisting of at least one first part in which channel structures are cut out in the surface and of a second part covering it in a sealing manner, with engagement regions for actuator elements being provided at pre-determined points. In accordance with the invention, the first part and/or the second part are made rigidly for the greater part; with them, however, having flexibly made regions, with the rigid and flexible regions being manufactured in one piece using two-component injection molding technology.

1 . A disposable cassette consisting of at least one first part in which channel structures are cut out in the surface and of a second part covering it in a sealing manner, with engagement regions for actuator elements being provided at pre-determined points, characterized in that the first part and/or the second part are made rigidly for the greater part; in that they, however, have flexibly made regions, with the rigid and flexible regions being manufactured in one piece using two-component injection molding technology.  
     
     
         2 . A disposable cassette in accordance with  claim 1 , wherein the flexible regions are formed in the engagement regions for the actuator elements.  
     
     
         3 . A disposable cassette in accordance with  claim 1 , wherein at least some of the channels consist of flexible material.  
     
     
         4 . A disposable cassette in accordance with  claim 1 , wherein valves are used as actuators.  
     
     
         5 . A disposable cassette in accordance with  claim 1 , wherein membrane pumps are used as actuators.  
     
     
         6 . A disposable cassette in accordance with  claim 1 , wherein restrictors or metering valves are used as actuators.  
     
     
         7 . A disposable cassette in accordance with  claim 1 , wherein the region of the channels in which the actuators are coupled are made shallower and with a larger channel cross-section.  
     
     
         8 . A disposable cassette in accordance with  claim 2 , wherein at least some of the channels consist of flexible material.  
     
     
         9 . A disposable cassette in accordance with  claim 2 , wherein valves are used as actuators.  
     
     
         10 . A disposable cassette in accordance with  claim 3 , wherein valves are used as actuators.  
     
     
         11 . A disposable cassette in accordance with  claim 2 , wherein membrane pumps are used as actuators.  
     
     
         12 . A disposable cassette in accordance with  claim 3 , wherein membrane pumps are used as actuators.  
     
     
         13 . A disposable cassette in accordance with  claim 2 , wherein restrictors or metering valves are used as actuators.  
     
     
         14 . A disposable cassette in accordance with  claim 3 , wherein restrictors or metering valves are used as actuators.  
     
     
         15 . A disposable cassette in accordance with  claim 2 , wherein the region of the channels in which the actuators are coupled are made shallower and with a larger channel cross-section.  
     
     
         16 . A disposable cassette in accordance with  claim 3 , wherein the region of the channels in which the actuators are coupled are made shallower and with a larger channel cross-section.  
     
     
         17 . A disposable cassette in accordance with  claim 4 , wherein the region of the channels in which the actuators are coupled are made shallower and with a larger channel cross-section.  
     
     
         18 . A disposable cassette in accordance with  claim 5 , wherein the region of the channels in which the actuators are coupled are made shallower and with a larger channel cross-section.  
     
     
         19 . A disposable cassette in accordance with  claim 6 , wherein the region of the channels in which the actuators are coupled are made shallower and with a larger channel cross-section.
