Okay, the user wants me to translate "stretcher-bed" into Turkish. Let me check the rules again. The first rule says to translate all content into Turkish. The second rule states that if the content is already in Turkish, 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 Turkish equivalent. A stretcher-bed is a type of bed that can be converted into a stretcher, often used in medical settings. In Turkish, this is commonly referred to as "ambulans yatak" or "stretcher yatak." However, "ambulans yatak" might be more specific to ambulance use, while "stretcher yatak" is a direct translation. I should confirm which term is more commonly used. Checking some sources, "stretcher yatak" seems to be the direct translation and is understood in Turkish medical contexts. So the translation would be "stretcher yatak." Since the original is in English, I don't leave it unchanged. The user wants only the translation, so I'll provide that without any extra text.
