Mitral regurgitation test catheter
Abstract
Abstract Translated from Japanese (57)【要約】 【課題】逆流試験中に生理的食塩水が左心房側に漏出し たり、或いは、生理的食塩水の注入速度を高めてもチュ ーブが抜け出ることなく、逆流試験を迅速に行うことが できるようにする。 【解決手段】生理的食塩水注入用チューブ2の少なくと も左心室内へ挿入する先端部2Aを細径チューブに形成 し、その細径チューブの先端に紡錘形の径大部3を設け る。径大部3の先端側に柔軟部3aを設けると共に、後 部に細径チューブに連通すると共に後方側に向けて開口 する噴出口4を設ける。 (57) [Summary] [PROBLEMS] To quickly perform a reflux test without leaking physiological saline into the left atrium during the reflux test, or without increasing the infusion rate of the physiological saline solution. Be able to do it. A distal end portion (2A) of a physiological saline injection tube (2) inserted into at least the left ventricle is formed in a small-diameter tube, and a spindle-shaped large-diameter portion (3) is provided at the distal end of the small-diameter tube. A flexible portion 3a is provided on the distal end side of the large-diameter portion 3, and a jet port 4 communicating with the small-diameter tube and opening toward the rear side is provided on the rear portion.
