Abstract: The present invention addresses the problem of providing an intraocular irrigating solution that allows the intraocular tissue to be sufficiently protected during ophthalmic surgery and further has high safety. The problem is solved by an intraocular irrigating solution containing at least one of active sulfur molecules of which examples include cysteine persulfide and glutathione persulfide.

Abstract: Occlusion of a blood vessel is improved by a medical treatment system including a ejection device that includes an insertion section insertable into a tissue of an animal and is capable of ejecting first liquid as a pulsating flow from a distal end of the insertion section and a control apparatus configured to bring the distal end of the insertion section close to a blood vessel in the tissue, which is a medical treatment target, and eject the first liquid as the pulsating flow from the distal end of the insertion section in a state in which second liquid is interposed in a region covering the blood vessel.
