HEADER

To provide a header to be used for a purification apparatus for purifying a fluid to be treated, the header dramatically improving discharge performance of gas in the purification apparatus to prevent the fluid to be treated from being drifted by gas remaining in the purification apparatus, purification performance from being reduced by reduction in contact area between the fluid to be treated and a purification carrier, and blood from being activated.SOLUTION: A header 200 to be used for a purification apparatus for purifying a fluid to be treated comprises: a cylindrical side part; a lid part that is formed by narrowing one opening in an axial direction of the cylindrical side part and has a through hole along the axial direction of the cylindrical side part; and a cylindrical port part 205 that makes the through hole communicate with a supply/discharge port 204. A filter 101 is provided on an inner surface of the cylindrical port part and has an opening part through which the fluid to be treated is to pass.SELECTED DRAWING: Figure 1 【課題】被処理流体を浄化する浄化機器に用いられるヘッダーにおいて、浄化機器内の気体の排出性能を飛躍的に向上させ、浄化機器内に残存した気体による被処理流体の偏流や、被処理流体と浄化担体の接触面積減少による浄化低能の低下や、血液の活性化を防ぐことを目的とするヘッダーを提供する。【解決手段】被処理流体を浄化する浄化機器に用いられるヘッダー２００であって、筒状の側部と、筒状の側部の軸線方向の一方の開口を狭めて形成され、筒状の側部の軸線方向に沿った貫通孔を有する蓋部と、貫通孔と被処理流体の供給／排出口２０４とを連通する筒状のポート部２０５と、を備え、筒状のポート部の内面にフィルタ１０１が設けられ、フィルタが被処理流体を通液する開口部を備えてなる、ヘッダー。【選択図】図１
