The game wiki says:

There is a theory behind the Intravenous Drip Chamber placed on her:

The pyrrhic victory of French forces in World War I was considered to be a first theory of Ribeyrolles, as the French forces suffered 1.300.000 casualties and 4.200.000 wounded during World War I.
The uniform she wore resembles the French forces in the Franco-Prussian War in which the French suffer a loss and 750.000 casualties from Prussia.

And it may also be a reference to the general unreliable mechanism of Ribeyrolles and malfunctions IRL
