CONNECTOR

摘要

A connector includes in a main body, first to third ports each having a flow channel allowing inflow or outflow of an infusion solution, an internal flow channel configured to communicate between flow channels of the first port and the second port, and a through hole connected to an internal flow channel. In the internal flow channel, an upstream side wall surface is provided which guides infusion solution flowing into the internal flow channel from the first port to the through hole, and reduces the cross-sectional area of the flow channel for the infusion solution near the through hole relative to the cross-sectional area of the flow channel of the first port in order to increase a flow rate of the infusion solution.

1. A connector comprising:
a main body; a first port, a second port and a third port provided at the main body, the first port, the second port and the third port each having a flow channel allowing inflow or outflow of fluid; an internal flow channel provided in the main body, the internal flow channel configured to communicate between the flow channel of the first port and the flow channel of the second port; a space portion provided in the third port and connected in fluid communication with the internal flow channel; and a wall surface provided in the internal flow channel, the wall surface configured to guide fluid flowing into the internal flow channel from the first port to the space portion; wherein the wall surface reduces a cross-sectional area of a flow channel for fluid near the space portion relative to a cross-sectional area of the flow channel of the first port.
