Problems solved by technology

[0004] However, there are three cocks in the three-way three-way cock, and the operation is complicated because the three cocks must be operated, and it is impossible to switch the flow path quickly.
[0005] In addition, in order to simplify these operations, for example, a device described in Patent Document 1 is known, but in this device, it is only possible to switch between the path (flow path) of the contrast medium and the path of the pressure monitor, and cannot Path switching to saline
In addition, even if it is desired to add a saline route, the mechanism will become complicated and difficult to implement

Abstract

A multiway cock (1) has a cock body (2), a cock member (3), and a cover (4). The cock body (2) has a circular tube part (20) that has a first portion (21) and a second portion (22) arranged parallel to each other along the axis (101) of the circular tube part. A first port (P1) and a second port (P2) are formed in the outer periphery of the first portion (21), and a third port (P3), a fourth port(P4), a fifth port (P5), and a sixth port (P6) are formed in the outer periphery of the second portion (22). The cock member (3) has a barrel part in which a first flow passage and a second flow passage are formed, a lever installation part (31), and a lever (32). Opening or closing of the first to sixth ports (P1-P6) formed in the first portion (21) and the second portion (22) can be selected byrotating the cock member (3).

Description

technical field [0001] The present invention relates to multi-way cocks and liquid supply circuits. Background technique [0002] In the treatment of coronary artery stenosis, less invasive treatment using a catheter is gaining popularity. During such an operation, a contrast agent is injected to confirm the position of the catheter and the state of the stenosis. In addition, flushing with physiological saline is suitably performed in order to ensure the contrast of the image. In addition, a pressure monitor that measures (detects) and displays arterial pressure is always connected to this circuit to confirm the arterial pressure, but when injecting contrast medium or saline, the connection of the pressure monitor is blocked. . [0003] In order to perform these operations, it is necessary to switch the flow path in the circuit, and as a mechanism for switching the flow path, a three-way three-way stopcock has conventionally been used. [0004] However, there are three c...
