Definitions

  • FIG. 1 shows a schematic sectional view through a particularly preferred embodiment of the infusion pump according to the invention
  • the actuator 90 is formed such that in a first position of the actuator 90, the inlet 20 communicates with the first chamber 50, whereas the communication between the first chamber 50 and the second chamber 70 is blocked by the actuator 90.
  • the first chamber 50 may be filled from the reservoir by a downward movement of the first piston 40 and the second chamber 70 may deliver its contents by continuous upward movement of the second piston 60 to the patient through the outlet 30 (see FIG ).
  • a second for example rotated by 180 ° position of the 2-way cock 90 (or its chick 90) communication between the inlet 20 and the first chamber 50 is blocked by the plug 90, but a communication between the first chamber 50 and the second chamber 70 is made via the connection channel 80.

Abstract

L'invention concerne une pompe à perfusion (10) pour le transport continu d'un fluide, comprenant une entrée (20), une sortie (30), un premier piston (40) monté à coulissement dans une première chambre (50), et un deuxième piston (60) monté à coulissement dans une deuxième chambre (70), caractérisée par un canal de liaison (80) reliant la première chambre (50) à la deuxième chambre (70), la première chambre (50) étant reliée à l'entrée (20) et la deuxième chambre (70) à la sortie (30). La pompe comprend au moins un élément de réglage (90) qui relie de manière communicante, dans une première position, l'entrée (20) à la première chambre (50) et, dans une deuxième position, la première chambre (50) à la deuxième chambre (70), la communication étant bloquée, dans la première position, entre la première chambre (50) et la deuxième chambre (70) et, dans la deuxième position, entre l'entrée (20) et la première chambre (50), et une commande agissant sur le premier piston (40), le deuxième piston (60) et l'élément de réglage (90) de sorte que lors du placement de l'élément de réglage (90) dans la première position, la première chambre (50) est remplie tandis que la deuxième chambre (70) est vidée à un débit prédéfini par l'intermédiaire de la sortie (30), et lors du placement de l'élément de réglage (90) dans la deuxième position, la première chambre (50) est vidée et la deuxième chambre (70) est remplie, l'écoulement constant par l'intermédiaire de la sortie étant maintenu au débit défini.
