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.

Connector

An injection needle assembly includes a needle having a needle point to puncture skin, a needle hub including a first member which holds the needle, and a second member in which a discharge part of a syringe is to be fitted, and an elastic member disposed inside the second member to make liquid-tight close contact with the inner surface of the second member, with the elastic member having an insertion hole in which the needle tube is inserted.
