- η σαμπρέλα = the inner tube
Greek nouns have grammatical gender, and the article has to match the noun in gender, number, and case.

In standard Greek, σαμπρέλα usually means an inner tube (for example, in a bicycle tire or other tire).
Depending on context, people may also use it more loosely for an inflatable ring, but the most standard meaning is inner tube. In this sentence, that meaning fits very naturally because it is something that can lose air and then be inflated again.
