She does not say the visit is canceled. She wants Takeo to leave before the delivery. The command concerns worrying, not leaving the hospital. She says Suna will handle every task for him. Neither Suna nor the task list appears in this line. Her own condition is the reason. She orders Takeo to hide his concern from her. 心配(しんぱい) すんな tells him not to worry, not merely to conceal it. She thinks Takeo is the one who needs medical care. 大丈夫(だいじょうぶ) refers to her reassurance about herself in this context.
