Title:
DRUG SOLUTION CIRCUIT, INJECTION SYSTEM, AND CLOSING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2018/181270
Kind Code:
A1
Abstract:
Provided is a drug solution circuit capable of more reliably preventing backflow of blood that can be installed easily on an injection device. A drug solution circuit 500 is equipped with a first base line 508 through which a first drug solution flows, a second base line 509 through which a second drug solution flows, a subject line 503 connected to the first base line 508 and the second base line 509, and a first closing part 100a having a first closing mechanism 120a for closing an internal circuit. The first closing mechanism 120a is equipped with a first moving member 122a1 and a second moving member 122a2, each having a flow path, and a first housing 124a that slidably accommodates the first moving member 122a1 and the second moving member 122a2. The circuit is configured so that the flow path of the second moving member 122a2 is opened after the flow path of the first moving member 122a1 has opened.
