摘要： A connection structure includes a chamber comprising a hollow housing, a diaphragm dividing the inside of the housing into a first space and a second space, and an output port outputting a gas in the second space with deformation of the diaphragm caused by pressure of a fluid flowing into the first space; a connection part comprising a coupling connected to the output port and being attached to a pressure detection device comprising a pressure sensor for detecting pressure of the gas output from the coupling; and a seal member being sandwiched between a side surface of the output port and a side surface of the coupling and moving while changing a sealing position when connecting or extracting the chamber to/from the connection part.

摘要： Provided are a connection structure and a blood purifying device which are capable of enhancing the durability of seal members. This connection structure 1 is roughly configured to be provided with: a connection part 3 attached to a main body 90 which has a housing 20, a diaphragm 25, a chamber 2, and a coupling 30 for connecting an output port 27, and which has a pressure sensor 10a for detecting a pressure PK of a gas K output from the coupling 30; and a seal member which is sandwiched by the lateral surface 270 of the output port 27 and the lateral surface 302 of the coupling 30, and which moves while changing the seal position when connecting or disconnecting the chamber 2 and the connection part 3.
