Problems solved by technology

[0004] However, the demand for cleanliness is increasing, and the growth of bacteria in the trace part where the injection needle is inserted, the generation of air stagnation in the sampling channel, the stagnation of liquid, and the sampling site caused by the sampling method (the place where the liquid is sucked) Contamination, etc., of the part where the syringe, etc. is inserted and its surroundings) is regarded as a problem

Embodiment Construction

[0038] Below, while referring to the attached Figure 1 Preferred embodiments of the invention will be described.

[0039] figure 1 The branch port 1 according to one embodiment of the present invention is shown, (A) shows the state where the cover 20 is attached to the case 2 of the branch port 1 , and (B) shows that the cover 20 is removed from the case 2 of the branch port 1 In the detached state, (C) shows a state in which the syringe 30 is attached to the opening end 7 of the branch channel 6 provided in the branch port 1 as a fluid communication unit. exist figure 1 In (A), a cover 20 is mounted on the case 2 of the branch port 1 to form a space 21 between the case 2 and the cover 20 , and the O-ring 22 provided on the cover 20 as a seal is crimped to the case. body 2, thereby ensuring the sealing of the cover 20. The casing 2 has: a main channel 5 including a fluid inflow channel 3 and a fluid outflow channel 4; a branch channel 6 branched from the main channel 5 wi...

Abstract

Provided is a branching port which makes it possible to prevent generation of accumulated air and fluid retention and to properly maintain a branching site and the cleanliness therearound, which enhances cleaning effects by a cleaning solution, and which enables monitoring even with failure to remember to attach a cap. A branching port provided with: a housing having a branching flow path, and a main flow path comprising a fluid inflow path and a fluid outflow path; a cap detachably attached to the housing; and a valve body for releasing a shut-off between the main flow path and the branching flow path when the cap has been attached or when the cap is removed and a fluid-circulating means that enables a fluid to circulate has been attached; wherein the branching port is characterized in that a bypass path that branches from the fluid inflow path and communicates with the branching flow path when the cap is attached is formed, and an on/off valve that shuts off leakage of the fluid to outside the housing from a branching section branching from the fluid inflow path to the bypass path when the cap is removed is provided.

Description

technical field [0001] The present invention relates to a branch port, and more specifically, to a branch port in which contamination prevention of a branch site is realized. Background technique [0002] In general, in a system that handles fluids that are required to maintain appropriate composition and safe cleanliness, such as dialysate and RO water, frequent extraction operations (sampling) of fluids are required for inspection and analysis. As a method of implementing such sampling, for example, Patent Document 1 discloses a technique in which valves are provided on intake pipes and return pipes branched from the main piping, and sampling pipes are connected to the intake pipes and return pipes, thereby Properly sample a part of the fluid flowing in the main piping. [0003] In addition, Patent Document 2 describes a method in which a dialysate or the like is collected by inserting a syringe needle into an elastic body of a mounting member built in a sampling port. ...
