CA 2304753

A measuring device (10) is disclosed which includes a proximal end portion (20) having an actuation member (24) thereon and a distal end portion (22) having an expandable member (28) thereon wherein the actuation member (24) and the expandable member (28) are in mechanical or fluid communication via a lumen (40) which extends therebetween such that actuation of the actuation member (24) causes the radial expansion of the expansion member (28) so that when the measuring device (10) is placed in a puncture with the distal end portion (22) in a blood vessel, the measuring device (10) may be withdrawn until the expandable member (28) contacts the wall of the blood vessel adjacent to the puncture to provide the user with an indication of the distance between and/or depth of the blood vessel beneath the skin of the patient.

La présente invention concerne un appareil de mesure (10) qui se compose d'une extrémité proximale (20) sur laquelle est placé un élément d'actionnement (24) et d'une extrémité distale (22) sur laquelle est placé un élément extensible (28). Dans ledit appareil, l'élément d'actionnement (24) et l'élément extensible (28) sont en communication mécanique ou fluidique via une lumière (40). Ladite lumière (40) s'étend entre les deux extrémités de manière à ce que le fait d'actionner l'élément d'actionnement (24) entraîne la détente radiale de l'élément extensible (28) afin que, lorsque l'appareil de mesure (10) est placé dans une ponction, avec l'extrémité distale (22) plongée dans un vaisseau sanguin, l'utilisateur puisse retirer ledit appareil (10) jusqu'à ce que l'élément extensible (28) entre en contact avec la paroi du vaisseau sanguin à côté de la ponction, ce qui lui permet de disposer d'une indication concernant la distance entre le vaisseau sanguin et la peau du patient et/ou la profondeur du vaisseau sanguin sous la peau du patient.
