Okay, the user wants me to translate "stretcher-bed" into Traditional Chinese. Let me check the rules again. The first rule says to translate all content into Traditional Chinese. The second rule states that if the content is already in Traditional Chinese, output it unchanged. The third rule is to provide only the translation result without explanations.
So, "stretcher-bed" is an English term. I need to translate it. A stretcher-bed is a type of bed that can be converted into a stretcher, often used in hospitals or for transporting patients. In Chinese, the term for this is usually "擔架床" (dānjià chuáng), where "擔架" means stretcher and "床" is bed.
Wait, but sometimes it might be referred to as "急救床" (jiùyì chuáng) which is emergency bed, but that's more about the purpose rather than the mechanism. The correct term would be "擔架床" since it specifically refers to a bed that can be converted into a stretcher. Let me confirm that. Yes, "擔架床" is the standard term.
Also, the user mentioned that if the content is already in Traditional Chinese, leave it as is. Since the input is in English, translation is needed. I should make sure there's no typo and that the translation is accurate. No explanations are to be provided, just the translation. So the answer should be "擔架床".
