Artificial-blood-vessel connector and artificial-blood-vessel unit

An artificial-blood-vessel connector for connecting an artificial blood vessel to an object to be connected by being mounted on the artificial blood vessel, wherein assuming a side of the artificial-blood-vessel connector which faces the object to be connected as a front side, a side of the artificial-blood-vessel connector opposite to the front side as a rear side, and a direction along which a center axis of the artificial blood vessel extends as an axial direction, the artificial-blood-vessel connector comprises:

• a connector portion which includes:
• a first cylindrical body portion where a male threaded portion and a flat surface portion where the male threaded portion is not formed are alternately formed along a circumferential direction of an outer peripheral surface;
• and a second cylindrical body portion which is formed on a rear-side end portion of the first cylindrical body portion, has an outer diameter smaller than an outer diameter of the first cylindrical body portion, and is configured to be fitted into the inside of the artificial blood vessel;
• a ferrule which includes:
• a cylindrical portion which is configured to be fitted on an outer peripheral surface of the second cylindrical body portion by way of the artificial blood vessel by being made to slide linearly toward the front side on a surface of the artificial blood vessel in a state where the second cylindrical body portion of the connector portion is fitted in the artificial blood vessel;
• and a pawl plate portion which is formed in a projecting manner along the axial direction from the cylindrical portion, and is brought into contact with the flat surface portion of the first cylindrical body portion;
• and
• a nut which includes a female threaded portion which is configured to threadedly engage with the male threaded portion of the first cylindrical body portion of the connector portion, and is configured to be connected to the connector portion by making the female threaded portion threadedly engage with the male threaded portion of the first cylindrical body portion in a state where the nut covers the ferrule when the second cylindrical body portion is fitted in the artificial blood vessel and the ferrule is mounted on the connector portion.
