Title:
TECHNIQUE SIMULATOR
Document Type and Number:
WIPO Patent Application WO/2020/031474
Kind Code:
A1
Abstract:
The present invention provides a technique simulator with which it is possible to experience that a pressure difference is generated by blocking a blood vessel using a balloon and it is possible to selectively administer a therapeutic agent to a specific region. A technique simulator (10A) comprises a flow path (12) including a liquid (L) that imitates blood, a liquid flow generation member for adding a flow to the liquid (L), and a catheter insertion port (14). The flow path (12) has a first branched flow path (24) and a second branched flow path (26) downstream of a branching unit (22). The technique simulator (10A) furthermore includes a pressure difference generation member for generating a pressure difference between the downstream side of the first branched flow path (24) and the downstream side of the second branched flow path (26). The liquid flow generation member generates pressure higher than the pressures applied to the downstream side of the first branched flow path (24) and the downstream side of the second branched flow path (26).
