Title (EN) MULTIPLE SEGMENTED PERISTALTIC PUMP AND CASSETTE
(FR) POMPE PÉRISTALTIQUE À MULTIPLES SEGMENTS ET CASSETTE
Abstract:
(EN) In various embodiments, a surgical cassette (100), configured to engage peristaltic pump rollers (201), may include two or more pump segments (103a, 103b) between a sheet (107) and a substrate (105) coupled to the sheet. The two or more pump segments on the cassette may produce additional flow (e.g., approximately twice the flow for two segments as opposed to one) than if the cassette had only one pump segment engaging the roller. Further, in some embodiments, the two or more pump segments and rollers on the roller head may be configured to provide a flow profile in which a peak of a pulse from a first pump segment is at least partially out of phase with a peak of a pulse from the second pump segment. The combined resultant flow may then have a flow profile with pulsation amplitudes that are smaller than the individual pump segment pulsation amplitudes.
(FR) Dans divers modes de réalisation, une cassette chirurgicale (100), configurée pour s'engager dans les cylindres de la pompe péristaltique (201), peut comprendre deux segments ou plus de pompe (103a, 103b) entre un feuillet (107) et un substrat (105) couplé au feuillet. Les deux segments ou plus de la pompe sur la cassette peuvent produire un flux plus important (par exemple, approximativement deux fois plus de flux pour la pompe à deux segments par opposition à celle à un segment) par rapport au flux obtenu si la cassette n'avait qu'un seul segment de pompe s'engageant dans les rouleaux. En outre, dans certains modes de réalisation, les deux segments ou plus de la pompe et les rouleaux sur l'assise des rouleaux peuvent être configurés pour fournir un profil de flux dans lequel un pic d'une impulsion provenant d'un premier segment de la pompe est au moins partiellement déphasé par rapport à un pic d'une impulsion provenant du second segment de la pompe. Les flux résultants combinés peuvent alors avoir un profil de flux ayant des amplitudes d'impulsion qui sont plus petites que les amplitudes d'impulsion d'un segment de pompe individuel.
