Okay, the user wants me to translate "stretcher-bed" into Portuguese. Let me check the rules again. The first rule says to translate all content into Portuguese. The second rule states that if the content is already in Portuguese, leave it as is. The third rule is to provide only the translation without any explanations.
So, "stretcher-bed" is an English term. I need to find the correct Portuguese equivalent. A stretcher-bed is a type of bed that can be converted into a stretcher, often used in medical settings. In Portuguese, the term might be "cama de maca" or "maca de cama." However, I should verify the most common term used in Brazil or Portugal.
Looking up some references, "cama de maca" seems to be the more commonly used term in medical contexts. Alternatively, "maca" alone might be sufficient, but since the user specified "stretcher-bed," combining both terms might be more accurate. I'll go with "cama de maca" as the translation. Let me make sure there's no existing Portuguese term that's more standard.
Yes, "cama de maca" is correct. So the translation should be "cama de maca." No explanations, just the translation. The user wants only the result, so I'll present that.
