Title
(EN) LINEAR PUMP AND METHOD
(FR) POMPE LINEAIRE ET PROCEDE
Abstract
(EN) The linear pump (10, 110) includes a housing (12, 112) and either two (20, 22) or one (120) flexible bladders each within a pump housing and interconnected to respective end caps (30, 32, 130, 132, 134, 136). Upon movement of a movable end cap relative to a stationary end cap, the volume in each bladder may be variably controlled to pump blood or another selected fluid. Linear movement of the end caps may be controlled by an attractive or repulsive force between end caps. The pump (110) with a permeable bladder (120) may be used to pump wastewater.
(FR) L'invention concerne une pompe linéaire (10, 110) comportant un carter (12, 112) et une (120) ou deux (20, 22) vessies flexibles, chaque vessie étant logée dans un carter de pompe et reliée à des bouchons terminaux respectifs (30, 32, 130, 132, 134, 136). Le mouvement d'un bouchon terminal mobile par rapport à un bouchon terminal fixe permet de commander de façon variable le volume dans chaque vessie de manière à pomper du sang ou un autre fluide. Le mouvement linéaire des bouchons terminaux peut être commandé par une force d'attraction ou de répulsion entre les bouchons terminaux. La pompe (110) comportant une vessie perméable (120) peut être employée pour pomper des eaux usées.
