An object is to provide a method for producing a port that can shorten the time for production. Provided is a method for producing a port including: sealingly inserting a sealing plug, through which a hollow needle can be pierced, into a part to be sealed of a port body, wherein the port body includes: a part to be sealed that has a tubular shape with a first end and a second end opposite to the first end; a connection part that has a tubular shape, and is continuous with the first end of the part to be sealed; and the part to be fitted that is formed in any one of an inner peripheral surface of the part to be sealed, an outer peripheral surface of the part to be sealed, and the second end of the part to be sealed; fitting a fitting part of a pulling-out prevention member into the part to be fitted, wherein the pulling-out prevention member includes: a body part that has a first surface and a second surface opposite to the first surface, and the fitting part that is continuous with the body part; and laying the body part on the sealing plug.

Method for producing port, and method for producing medical liquid bag

An object is to provide a port that is capable of securely preventing pulling-out of a sealing plug from a port body. Provided is a port including: a sealing plug through which a hollow needle can be pierced; a port body having a hollow structure with the sealing plug disposed therein; and a pulling-out preventing member to be attached to the port body. The port body includes: a part to be sealed that has a tubular shape with a first end and a second end opposite to the first end, and is configured so that the sealing plug is sealingly inserted into the part to be sealed; a connection part that has a tubular shape, is continuous with the first end of the part to be sealed, and has an outer periphery connected to the bag body to be filled with a medical liquid; and a part to be fitted that is formed in any one of an inner peripheral surface of the part to be sealed, an outer peripheral surface of the part to be sealed, and the second end of the part to be sealed. The pulling-out preventing member includes: a body part that has a first surface directed toward the first end of the part to be sealed within the part to be sealed; a restriction part that is formed on the first surface of the body part and restricts movement of the sealing plug toward the second end of the part to be sealed; and a fitting part that comes into fitting engagement with the part to be fitted of the port body.
