Abstract

PROBLEM TO BE SOLVED: To provide a dialysis probe capable of stably performing an analysis with high accuracy for a long period of time even if the inflow and outflow rates of a perfusate are not completely equalized.SOLUTION: The dialysis probe 1 includes a tubular dialysis membrane 2 having a sealed tip portion; a support tube 3 having a tip coupled to the rear end of the dialysis membrane 2; a cap portion 4 for securing the rear end of the support tube 3; an inlet conduit 5 extending through the cap portion 4 toward the tip of the dialysis membrane 2 within a space 10 to guide the perfusate into the space 10; an outlet conduit 6 extending through the cap portion 4 toward the tip of the dialysis membrane 2 within the space 10 to guide the perfusate in the space 10 outside the space 10; and at least one air-exposure through-hole 7 provided in the cap portion 4 for maintaining the space 10 at atmospheric pressure. The inlet conduit 5 has a longer protruding length from the rear end of the support tube 3, when compared to the outlet conduit 6.
【課題】灌流液の流入流量および流出流量を完全に等しくしなくても、長時間にわたって、精度の高い分析を安定して行うことができる透析プローブを提供する。 【解決手段】本発明に係る透析プローブ1は、先端部が封止された管状の透析膜2と、透析膜2の後端部に先端部が連結された支持管3と、支持管3の後端部を固定するキャップ部4と、キャップ部4を貫いて空間10内を透析膜2の先端部に向かって延び、空間10に灌流液を導く入口導管5と、キャップ部4を貫いて空間10内を透析膜2の先端部に向かって延び、空間10内の灌流液を該空間10外に導く出口導管6と、キャップ部4に設けられた、空間10を大気圧に保つための少なくとも1つの大気開放貫通穴7とを備え、支持管3の後端部を基準とした場合の突出長は、出口導管6よりも入口導管5の方が長くなっている。 【選択図】図1
