Milk in tubing and pump, can I save my spectra?

I've been using a secondhand blue spectra. for 30 seconds at the end of my pumping I heard a squishing sound and saw milk in both tubes. stopped the pump but it was too late. after removing the tubing, the pump makes a fluttering sound like there's moisture inside.

I ran the pump disconnected for 15 minutes without change. what else can I do to save my pump? or is it over?
