Abstract
Official abstract text for this publication.
A peristaltic pump and an analyzer for testing a biological sample, wherein the pump includes a pump head that is constructed as a screwless assembly, wherein the pump includes a bayonet and/or a beam coupling, and/or wherein rollers of the pump are configured to be pivoted about corresponding pivot axes that intersect with the roller axes.
First claim
Opening claim text (preview).
What is claimed is: 1. A peristaltic pump for conveying a fluid within a cartridge, comprising: a motor; and a pump head configured to be rotated about a central axis by means of the motor, wherein the pump head comprises a main body, a plurality of rollers for contacting the cartridge and a plurality of brackets for the rollers, wherein each of the rollers is mounted to one of the brackets and is configured to be rotated about a roller axis, wherein each of the brackets is mounted to the main body and is configured to be pivoted about a pivot axis relative to the main body, and wherein each pivot axis runs through an associated roller. 2. The pump according to claim 1 , wherein each of the rollers comprises a cone shaped roller including a free end that is turned towards the central axis. 3. The pump according to claim 1 , wherein each roller comprises a cone-shaped roller head and a roller shaft. 4. The pump according to claim 1 , wherein each of the brackets comprises a pair of pivots, wherein each pair of pivots define one pivot axis. 5. The pump according to claim 4 , wherein the main body comprises a plurality of sockets and includes at least one of the following features: each of the sockets is configured to pivotably receive at least one of the pivots; or each of the pivots is clipped in one of the sockets. 6. The pump according to claim 5 , wherein each of the pivots comprises a stop limiting pivoting movement of the rollers. 7. The pump according to claim 1 , wherein the rollers being clipped in the brackets and the brackets being clipped in the main body. 8. The pump according to claim 1 , wherein the pump comprises a plurality of roller bearings. 9. The pump according to claim 8 , wherein each of the roller bearings is clipped in one of the brackets. 10. The pump according to claim 8 , wherein each of the brackets comprises a receptacle for receiving one of the roller bearings. 11. The pump according to claim 8 , wherein each of the rollers comprises a bearing surface for the roller bearings, each roller being clipped into one of the roller bearings with its bearing surface. 12. The pump according to claim 1 , the pump further comprising a coupling apparatus for connecting the pump head to the motor, wherein the coupling apparatus is constructed as a beam coupling, wherein the coupling apparatus comprises an outer spring for a tumbling motion of the pump head and an inner spring for an axial motion of the pump head. 13. The pump according to claim 12 , wherein the coupling apparatus is flexible and configured to compensate for misalignment and an offset between the pump head and the motor. 14. The pump according to claim 12 , wherein the outer spring is formed by the wall of the coupling apparatus.
