経皮カテーテルおよび経皮カテーテル用チューブの製造方法
Abstract:
(EN)
[Problem] To provide: a percutaneous catheter which is capable of inhibiting kinking of a portion in which side holes are provided; and a method for producing a percutaneous catheter tube, said method being capable of improving productivity by forming the side holes using a relatively simple method. [Solution] This percutaneous catheter 30 is provided with: a tubular reinforcement body 320 which has, provided in spaces between a plurality of wires W braided into a mesh, a plurality of gaps G, and first openings H1 which are formed so as to have a larger opening area than the gaps; and resin layers 331, 332 which are provided so as to cover the reinforcement body, and which are provided with second openings H2 disposed so as to overlap the first openings. Side holes 63 which communicate with a lumen are formed in a portion in which the first openings and the second openings overlap.
(FR)
Le problème décrit par la présente invention est de fournir : un cathéter percutané qui est capable d'empêcher le vrillage d'une partie dans laquelle des trous latéraux sont prévus ; et un procédé de production d'un tube de cathéter percutané, ledit procédé étant apte à améliorer la productivité en formant les trous latéraux à l'aide d'un procédé relativement simple. À cet effet, l'invention concerne un cathéter percutané 30 comprenant : un corps de renforcement tubulaire 320 qui présente, disposée dans des espaces entre une pluralité de fils W tressés en un maillage, une pluralité d'intervalles G, et des premières ouvertures H1 qui sont formées de façon à avoir une aire d'ouverture plus grande que les intervalles ; et des couches de résine 331, 332 qui sont disposées de façon à recouvrir le corps de renforcement, et qui comportent des secondes ouvertures H2 disposées de façon à chevaucher les premières ouvertures. Des trous latéraux 63 qui communiquent avec une lumière sont formés dans une partie dans laquelle les premières ouvertures et les secondes ouvertures se chevauchent.
