Sounds like a fascinating project, Antonio.
Off the top of my head, France has the "Insigne des blessés militaires" - instituted 11 Decemeber 1916 as a ribbon only award consisting of a small red star on a white, blue, yellow, and red ribbon. That's only worn until a campaign medal is issued for the campaign in which the wound was received, then the star should be pinned to that ribbon instead. However, unofficial "wound medals" are popular and even tolerated in uniform... and 100 years after it was instituted - 17 August 2016 - the French created a War Wounded Medal using the same ribbon, with the medal being a red-enamelled star in a gold wreath of oak and laurel leaves.
Got a stack of marking to do but I shall ferret around some more... only 31 more countries to go! Or 30, seeing as you have already attended to the Spanish one!
