Document Type and Number:
WIPO Patent Application WO/2020/054433
Kind Code:
A1
Abstract:
Provided is a connection member which is not limited by the material, the tube thickness, the tube diameter, or the like, of an aspiration side tube or a discharge side tube which are connected to a pump, and which is capable of resolving the inconvenience of fitting these tubes. The connection member 5 comprises a pump attachment section 12, a tube connection section 10, and a flow path forming section 13. In each of an aspiration path section 16 and a discharge path section 17 of the flow path forming section 13, at least one section has a membrane part 16a, 17a that is deformable by pressure from a liquid flowing through the interior thereof. The flow path forming section 13 has a shape that allows attachment of sensors 37, 38 such that the membrane parts 16a, 17a are disposed opposite the sensors 37, 38 which detect the flow state of a liquid flowing through the interior of the aspiration path section 16 and the discharge path section 17 by the deformation of the membrane part 16a, 17a.
