A flow path device includes a first portion, and a second portion. The first portion includes a resin first body and a first reinforcement. In the first body, a first connector connects a first outer portion and a first joint having a groove pattern defining a first flow path. The first reinforcement is between and bonded to the first outer portion and the first joint, and includes first protrusions protruding from the first body and including two specific-shaped portions. The second portion includes a resin second body and a second reinforcement. In the second body, a second connector connects a second outer portion and a second joint, and through-holes connect to the first flow path. The second reinforcement is between and bonded to the second outer portion and the second joint, and includes second protrusions protruding from the second body and including two specific-shaped portions.

Flow path device, method for manufacturing flow path device, flow path measuring device, and inspection apparatus

A particle separation device comprises, inside a plate-like base body, a straight main flow path including a flow inlet and a plurality of branch flow paths. The flow inlet includes a sample flow inlet and a pressing flow inlet. The sample flow inlet is connected to the main flow path via a first bending part, a first straight part, a second bending part, and a second straight part. Widths in the first bending part and the first straight part are larger than widths in the second bending part and the second straight part. The widths in the second bending part and the second straight part are larger than a width in the main flow path. The pressing flow inlet is connected to the side surface of the main flow path via a third straight part, a third bending part, a fourth straight part, and a fifth straight part.

Measurement apparatus

Analysis chip for biochemical inspection machine

A flow path device comprises a plate-like measurement flow path device and a plate-like separation flow path device. The measurement flow path device includes a first flow path for measuring specific particles on a first fluid and connected to a third flow path and a second flow path for correction and passing a second fluid, not including the specific particles. The separation flow path device includes a fourth flow path for separating and selecting the specific particles from a sample and collecting a fluid. The separation flow path device is on the measurement flow path device's upper surface. The sample passes through a fifth flow path, the upper surface's opening, and flows into the fourth flow path from an opening in the separation flow path device's lower surface. The first fluid passes through the lower surface's opening, and flows into the first flow path from the upper surface's opening.

Flow path device and measurement apparatus

Analysis chip for biochemical testing machine

A measurement apparatus according to the present disclosure is a measurement apparatus capable of measuring particles in a fluid and comprises: a flow path device including a first flow path with translucency through which a first fluid including the particles passes and a second flow path with translucency through which a second fluid which does not include the particles passes; an optical sensor facing the flow path device, irradiating each of the first flow path and the second flow path with light, and receiving light passing through each of the first flow path and the second flow path; and a controller measuring the particles by comparing an intensity of light passing through the first flow path and an intensity of light passing through the second flow path, each of which is obtained by the optical sensor.
