Title (EN) CATHETER, SEPARATOR, AND SUCTION SYSTEM
(FR) CATHÉTER, SÉPARATEUR ET SYSTÈME D'ASPIRATION
(JA) カテーテル、セパレータおよび吸引システム
Abstract:
(EN) A catheter 50 is provided with: an inner layer member 61 having a long lumen LM extending along the longitudinal axis and having the inner circumferential surface 61a in contact with the lumen LM; an outer layer member 71 having the outer circumferential surface 62a of the catheter 50; a coil-like first reinforcing member 71 provided, between the inner circumferential surface 61a and the outer circumferential surface 62a, outside the inner layer member 61; a braid-like second reinforcing member 72 provided, between the inner circumferential surface 61a and the outer circumferential surface 62a, outside the first reinforcing member 71; and the like. According to this technique, the rigidity, the insertability, the torque transmission property, and the kink resistance of the catheter can be ensured while the low thickness of the catheter is maintained.
(FR) Cette invention concerne un cathéter 50 comprenant : un élément de couche interne 61 ayant une lumière longue LM s'étendant le long de l'axe longitudinal et dont la surface circonférentielle interne 61a est en contact avec la lumière LM ; un élément de couche externe 71 comprenant la surface circonférentielle externe 62a du cathéter 50 ; un premier élément de renfort spiralé situé, entre la surface circonférentielle interne 61a et la surface circonférentielle externe 62a, à l'extérieur de l'élément de couche interne 61 ; un second élément de renfort tressé 72 situé, entre la surface circonférentielle interne 61a et la surface circonférentielle externe 62a, à l'extérieur du premier élément de renfort 71 ; et autre. Selon cette technique, la rigidité, l'aptitude à l'insertion, la propriété de transmission de couple et la résistance à la torsion du cathéter peuvent être garanties tout en conservant une faible épaisseur de cathéter.
(JA) カテーテル50は、長手軸に沿った細長いルーメンLMを有し、ルーメンLMに接する内周面61aを有する内層部材61と、カテーテル50の外周面62aを有する外層部材71と、内周面61aと外周面62aとの間で、内層部材61の外側に設けられたコイル状の第1補強部材71と、内周面61aと外周面62aとの間で、第1補強部材71の外側に設けられたブレイド状の第2補強部材72などを備える。こうした手法により、カテーテルの厚みを小さく維持したままカテーテルの剛性や押し込み性、トルク伝達性、耐キンク性を確保できる。
