。
She rushed to his bedside.
Literal
She [topic-は] hurriedly his sickbed [to-へ] rushed-over.
病床 ('sickbed') is a Sino-Japanese compound made of 病 ('illness') + 床 ('bed, floor'); it's a more formal, slightly literary word than the everyday ベッド or 寝床, and it carries a heavy emotional weight — you 駆けつける to a 病床 in scenes of family crisis. 駆けつける itself is a compound verb: 駆ける ('run, gallop') + つける ('attach, fasten'), which together means 'rush to and arrive at.' The つける element here doesn't mean 'attach' literally but signals reaching the destination.
