Title
(EN) MINIATURE INFUSION PUMP
(FR) POMPE D'INJECTION MINIATURE
Abstract
(EN) A pressure pump apparatus (10) for fluids in flexible tubing (12), which comprises a pressure member (30) of generally circular periphery adapted for orbital motion about an axis of rotation (32). A sleeve member (34) is positioned about the pressure member (30) and defines channel means (36, 38) for receiving and retaining the flexible tubing (12) in a predetermined position between the pressure member (30) and sleeve member (34), and surrounding the pressure member (30). The sleeve member (34) may be divided into a pair of substantially semi-circular jaws (34a, 34b) attached together at one end in hinged relation, to permit opening and closing of the jaws about the pressure member (30) to facilitate installation of the tubing (12).
(FR) Un appareil a pompe de pression (10) pour des fluides se trouvant dans des tubes flexibles (12), lequel appareil comprend un organe de pression (30) ayant une peripherie sensiblement circulaire concue pour un mouvement orbital autour d'un axe de rotation (32). Un manchon (34) est positionne autour de l'organe de pression (30) et definit des moyens de canaux (36, 38) de reception et de retenue du tube flexible (12) dans une position predeterminee entre l'organe de pression (30) et le manchon (34), et entourant l'organe de pression (30). Le manchon (34) peut etre divise en une paire de machoires sensiblement semi-circulaires (34a, 34d) assujetties l'une a l'autre a une extremite de maniere articulee, pour permettre l'ouverture et la fermeture des machoires autour de l'organe de pression (30) pour faciliter l'installation du tube (12).
