First Claim
Patent Images
1. Peristaltic pump comprising a rotor incorporating rollers and a mobile jaw that is provided with a bearing member and assumes:
- an open position in which it is moved away from the rotor, the bearing member then being move away from a fixed counter-member on the pump (1), with the result that a tube on which said pump must act may be fitted between the jaw and the rotor, on the one hand, and between the bearing member and the counter-member, on the other hand, and a closed position in which the mobile jaw is moved close to the rotor, which moves the bearing member toward said counter-member, with the result that said tube is gripped between a curved bearing surface of the mobile jaw and at least one roller of the rotor, on the one hand, and between the bearing member and the counter-member, on the other hand, this pump being characterized in that it further comprises;
a sensor of the force exerted between the bearing member and the counter-member; and
a processing unit comprising means for determining, from the signal supplied by the sensor, if predetermined conditions indicative of correct positioning of the tube between the bearing member and the counter-member have been satisfied.
