Embodiment 1

[0108] An ETRF module, which is formed by inserting a hollow fiber membrane bundle into the main body shell and filling the inside with water. The main body shell has four fluid ports, and the length direction of the module and the direction perpendicular to the length direction of the module are in compliance with JIS T3250 (2011) 4.4.4 of the coupling type fluid port, in this ETRF module, the plug body of the present invention is installed, and the connection part of the dialysis device is installed. The connection part is in the shape of a synthetic resin tube, and the tip of the connection part presses the center of the cap part and penetrates it.

[0109] The portion through which the connecting portion near the center of the cover portion of the plug penetrates, the fluid port sealing portion, and the connecting portion sealing portion are each made of a styrene-based thermoplastic elastomer with a Shore A hardness of 70 degrees. The cover portion is formed by two-color ...

Abstract

A plug which is detachably attached to a fluid port of a medical module, wherein a lid portion of the plug comprises a part to be penetrated through which a cylindrical tubular connection part of a fluid treatment device is capable of penetrating the lid portion, in a state where the plug is attached to the fluid port, when the connection part and the fluid port are connected so as to allow fluid to pass therethrough. The part to be penetrated has a thickness of 0.2 to 3.0 mm and is formed with a soft synthetic resin having a flexural modulus of 100 to 1500 MPa or with an elastic body having a Shore A hardness of 40 to 90. Additionally, the plug comprises a connection part sealing part which liquid-tightly abuts the connection part in a state where the connection part is inserted inside the plug. Thus, the medical module and the fluid treatment device can be connected hygienically in a simple manner without removing the plug.

Description

technical field [0001] The present invention relates to a plug body, a medical component and a medical system. The plug body can be detachably mounted on a fluid port of a medical component that can be fluidly connected to a cylindrical tubular connection part of a fluid processing device. The component is formed by the plug body covering the fluid port, and the medical system is connected with the medical component and the fluid treatment device. Examples of such medical components include medical devices used for extracorporeal circulation of body fluids represented by blood and plasma, and filters widely used to circulate and process medical fluids. Background technique [0002] As a conventionally well-known technique, a fluid processing device is connected to a medical module having a fluid port, and a fluid is passed through the medical module to perform fluid processing. This is a technology that connects components corresponding to the liquid to be treated and the p...
