Tube connection system and tube connector set

A tube connection system comprising:

• a first fluid-path member and a second fluid-path member;
• a holder that holds the first fluid-path member and the second fluid-path member;
• a heater;
• and
• an extractor, wherein
• each of the first fluid-path member and the second fluid-path member includes an internal channel penetrating in a first direction, a fluid path end located at an end of the internal channel and capable of being fusion-bonded, and a sealing element having a higher thermal conductivity than that of the fluid path end and covering the fluid path end,
• the first fluid-path a member includes first tube connector,
• the second fluid-path member includes a second tube connector,
• each of the first tube connector and the second tube connector includes a tube attachment portion disposed on a first side in the first direction, the fluid path end disposed on a second side in the first direction, and the internal channel penetrating from the tube attachment portion to the fluid path end in the first direction,
• the holder includes a first joint frame that holds the first tube connector and a second joint frame that holds the second tube connector,
• when the first joint frame and the second joint frame are fitted together and integrated, the first joint frame and the second joint frame are capable of holding the first tube connector and the second tube connector with the sealing elements of the first fluid-path member and the second fluid-path member facing and being pressed against each other,
• at least one of the first joint frame and the second joint frame includes an elastic function portion,
• the elastic function portion causes the sealing elements of the first fluid-path member and the second fluid-path member to be pressed against each other,
• the heater is capable of heating the sealing element of each of the first fluid-path member and the second fluid-path member, and
• the extractor is capable of pulling out the sealing element of each of the first fluid-path member and the second fluid-path member in a second direction orthogonal to the first direction.
