Title
(EN) METHOD AND DEVICE TO PERFORATE, IN PARTICULAR TO PUNCTURE A MEMBRANOUS MEMBER WHILE UTILIZING VACUUM FIXATION
(FR) PROCEDE ET DISPOSITIF PERMETTANT DE PERFORER, NOTAMMENT PAR PIQURE, UN ORGANE A MEMBRANE TOUT EN UTILISANT UNE FIXATION PAR LE VIDE
Abstract
(EN)
A new method is given to transfer a specific amount of solid, gaseous or fluid medium to or from a space through the wall of a flexible membraneous member enclosing said space. A sunction force is applied on part of the membrane surface, resulting in a locally increasing yet allowable deformation by tensioning of said surface. The pre-tensioned membrane is then perforated by a needle-shaped instrument. This so-called vacuum fixation is obtained by using a cup-shaped member (2) of which the circumferential edge is first brought into a sealing contact with the membrane surface before the suction force can be applied. The device utilizing this new method is provided with a hollow guiding tube (3) to manually guide a known instrument such as a catheter-needle unit and one end of this hollow guiding tube is provided with a cup-shaped member (2) which is connected to a vacuum outlet, preferably a disconnectable vacuum outlet.

Nouveau procédé de transfert d'une quantité spécifique d'un milieu solide, gazeux ou fluide vers ou à partir d'un espace au travers de la paroi d'un organe flexible à membrane délimitant cet espace. Une force d'aspiration est appliquée sur une partie de la surface de la membrane, ce qui se traduit par une déformation s'accroissant localement mais admissible, en soumettant la surface à une tension. La membrane tendue au préalable est alors perforée à l'aide d'un instrument en forme d'aiguille. La fixation dite "par le vide" est obtenue en utilisant un organe en forme de cuvette (2) dont le bord de circonférence est d'abord mis en contact étanche avec la surface de la membrane avant de pouvoir appliquer la force d'aspiration. Le dispositif utilisant ce nouveau procédé est pourvu d'un tube de guidage creux (3) permettant de guider manuellement un instrument connu tel qu'une unité d'aiguille de cathéter, et une extrémité de ce tube de guidage creux est pourvue d'un organe en forme de cuvette (3) relié à un orifice de sortie sous vide, de préférence un orifice de sortie sous vide déconnectable.
