| 摘要 |
The invention concerns an improved peristaltic pump including at least one elastically flattenable tube and at least two assemblies of two pressing elements placed opposite each other, each of said assemblies being configured to compress the tube at a different point from the pump. These two pressing elements of a single assembly are placed on either side of the tube, at least one of the pressing elements of this single assembly is mobile such that the distance separating the pressing elements of the single assembly is adjustable, to allow the pressing members to be placed in a rest position, in which the tube is not compressed by the pressing elements, or to allow the pressing elements to be placed in a position compressing the tube. Advantageously, the adjustment is made automatically when the peristaltic pump or pumping is started or stopped. |
