Patent ID: 8393880

Claim:
A peristaltic pump comprising 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 said tube at a different point of said pump, wherein said two pressing elements of a single assembly are placed on either side of said tube, at least one of the pressing elements of said single assembly is mobile such that a distance separating said pressing elements of said single assembly is adjustable, from said point of the pump where said assembly of pressing elements is configured to compress said tube, to allow said pressing elements to be placed in a rest position, in which said tube is not compressed by said pressing elements, or a compression position to allow said pressing elements to be placed in a position compressing said tube, wherein at least the pressing elements placed on a first side of the tube are controlled by at least one actuator able to move said pressing elements on the first side of the tube between the rest position, where said pressing elements on the first side of the tube are set back from the pressing elements placed on another side of said tube without pressing the tube, and a position referred to as the compression position of the tube, wherein said actuator automatically moves said pressing elements towards said compression position of the tube when said peristaltic pump or pumping is started, and conversely towards the rest position when said peristaltic pump or pumping is stopped so as to release said tube.
