It seems that in the underlying concepts that show that this device can work are already well known. That is, it is known that vacuum suction helps wounds and there are already existing approved devices that already do that.
So the only think she was testing is whether the rather simple mechanics of that particular device will work as expected.
So it does not seem to be something especially dangerous.
