Title
(EN) PLATEN FOR PERISTALTIC INFUSION PUMP
(FR) PLATEAU POUR POMPE DE PERFUSION PÉRISTALTIQUE
Abstract
(EN)
A platen assembly positionable opposite a pumping mechanism of an infusion pump has a first platen member rotatably coupled to the pump to pivot about a first hinge axis and a second platen member rotatably coupled to the first platen member to pivot about a second hinge axis different from the first hinge axis. When the platen assembly is in a pump operating position, respective platen surfaces of the platen members follow a single surface profile, for example an arcuate surface profile in the case of a curvilinear peristaltic pump. The platen assembly may have a damage-tolerant design including a plurality of alignment counter-features arranged to mate with corresponding alignment features on the pump, wherein the platen assembly may still close after the pump is dropped or damaged only if resulting deformation of the platen assembly is within an allowable tolerance for safe pumping.
(FR)
La présente invention concerne un ensemble plateau pouvant être positionné à l'opposé d'un mécanisme de pompage d'une pompe de perfusion comprenant un premier élément de plateau accouplé rotatif à la pompe pour pivoter autour d'un premier axe de charnière et un second élément de plateau accouplé rotatif au premier élément de plateau pour pivoter autour d'un second axe de charnière différent du premier axe de charnière. Lorsque l'ensemble plateau est dans une position de fonctionnement de la pompe, des surfaces de plateau respectives des éléments de plateau suivent un profil de surface unique, par exemple un profil de surface arqué dans le cas d'une pompe péristaltique curviligne. L'ensemble plateau peut avoir une conception tolérante aux dommages comprenant une pluralité de contre-éléments d'alignement agencés pour s'accoupler avec des éléments d'alignement correspondants sur la pompe, l'ensemble plateau pouvant encore se fermer après que la pompe a chuté ou est endommagée uniquement si la déformation résultante de l'ensemble plateau se trouve dans une tolérance admissible pour un pompage sûr.
