A Foley type catheter of the type including an elongated flexible tube and an inflation lumen, the distal end of the tube being provided with a membrane that is inflated into a balloon by fluid passage though the lumen, wherein to retain the distal end interiorly of a bladder, and a drainage eye, wherein to enable the catheter to drain urine therefrom. The proximal end of the tube is provided with a fluid control valve and a fluid pump, each hand operated as desired. The pump is in the form of a squeeze bulb and/or aspirator and adapted to deform to supply and/or withdraw fluid into and from the lumen and selectively inflate/deflate the membrane.

L'invention concerne un cathéter du type Foley du type comprenant un tube souple allongé et une lumière de gonflage, l'extrémité distale du tube étant pourvue d'une membrane gonflée en un ballonnet en faisant passer du fluide à travers la lumière afin de retenir l'extrémité distale à l'intérieur d'une vessie, et d'un AEil de drainage pour permettre au cathéter de drainer de l'urine à partir de celui-ci. L'extrémité proximale du tube est pourvue d'une valve de commande de fluide et d'une pompe à fluide, chacune actionnée à la main si souhaité. La pompe a la forme d'une poire et/ou d'un aspirateur, et est adaptée pour se déformer afin d'alimenter et/ou de retirer du fluide de la lumière, et de gonfler/dégonfler sélectivement la membrane. Dans un mode de réalisation, la pompe a la forme de soufflets plissés et aplatis axialement comportant des parois d'extrémité poussées ensemble dans une mise en prise de retenue analogue à une ventouse, où un ressort hélicoïdal agit pour restaurer la forme.
