Infusion solution oxygenation device and infusion solution oxygenation system

An infusion solution oxygenation system comprising:

• a catheter configured to supply an oxygen-containing gas to an infusion solution in an infusion solution container;
• a gas supply unit configured to supply the oxygen-containing gas to the catheter;
• a container pressure sensing unit configured to sense an internal pressure of the infusion solution container;
• and
• wherein the gas supply unit is configured to control supply of the oxygen-containing gas based on the internal pressure sensed by the container pressure sensing unit.

A method for supplying to an infusion solution, the method comprising:

• supplying an oxygen-containing gas to an infusion solution in an infusion solution container via a catheter, the catheter being connected to a catheter connection portion;
• supplying the oxygen-containing gas to the catheter connection portion via a gas supply unit;
• sensing an internal pressure of the infusion solution container with a container pressure sensing unit;
• and
• controlling the supply of the oxygen-containing gas by the gas supply unit based on the internal pressure sensed by the container pressure sensing unit.
