A body-wall-contact-type water tank () is equipped with: a water-tank body for storing a fluid to be supplied into a body cavity, and positioned so as to contact a body wall (); a through-hole which conveys the fluid stored in the water-tank body into the body cavity via an incision formed in the body wall (), and which is formed in the bottom section of the water-tank body; and a connecting means for connecting, in a fluid-tight manner, the water-tank body to the body wall () and/or to a retractor () attached to the incision.

An artificial blood has a trunk portion with both ends connected to blood vessels, and access branch portions and a shunt branch portion branched from the trunk portion. The access branch portions are disposed with a solid column-shaped access port that plugs these branch portions. The access port has a solid center portion and a tube-shaped peripheral portion disposed to surround the center portion. The peripheral portion is harder than the center portion and prevents the needle from deviating from the inside of the center portion. This enables a puncture to be easily made in a therapy in which a puncture is highly frequently made in a blood vessel.
