Title
(EN) PUMP HEAD FOR A PERISTALTIC PUMP
(FR) TÊTE DE POMPE POUR POMPE PÉRISTALTIQUE
Abstract
(EN)
Pump heads for peristaltic pump assemblies are provided. For example, a pump head for a peristaltic pump comprises an occlusion bed, a rotor guide, a rotor assembly positioned between the occlusion bed and the rotor guide, and a pathway for tubing. The pathway comprises an inlet portion, an outlet portion, and a connecting portion that connects the inlet and outlet portions. The inlet portion is defined between the occlusion bed and the rotor guide, the outlet portion is defined between the occlusion bed and the rotor guide, and the connecting portion is defined between the occlusion bed and the rotor assembly. Further, the occlusion bed is movable with respect to the rotor guide and the rotor assembly. In exemplary embodiments, the pump head urges fluid flow through the tubing to supply a cooling fluid to a medical probe assembly for delivering energy to a patient's body.

L'invention concerne des têtes de pompe pour ensembles pompes péristaltiques. Par exemple, une tête de pompe pour une pompe péristaltique comprend un lit d'occlusion, un guide de rotor, un ensemble rotor positionné entre le lit d'occlusion et le guide de rotor et un trajet pour le tube. Le trajet comprend une partie d'entrée, une partie de sortie et une partie de raccordement qui relie les parties d'entrée et de sortie. La partie d'entrée est définie entre le lit d'occlusion et le guide de rotor, la partie de sortie est définie entre le lit d'occlusion et le guide de rotor et la partie de raccordement est définie entre le lit d'occlusion et l'ensemble rotor. En outre, le lit d'occlusion est mobile par rapport au guide de rotor et à l'ensemble rotor. Dans des modes de réalisation donnés à titre d'exemple, la tête de pompe pousse un écoulement de fluide à travers le tube pour fournir un fluide de refroidissement à un ensemble sonde médicale pour administrer de l'énergie au corps d'un patient.
