「按体重计算剂量（mg/kg，含浓度换算毫升）」是什么？What is the Weight-Based Dosage Calculator (mg/kg, with mL from concentration) tool?

如何使用「按体重计算剂量（mg/kg，含浓度换算毫升）」？How do I use the Weight-Based Dosage Calculator (mg/kg, with mL from concentration) tool?
在「按体重计算剂量（mg/kg，含浓度换算毫升）」中，填写「体重单位」、「体重（0.1–700 kg）」、「每公斤剂量 mg/kg」、「单次最大剂量 mg（可选）」、「每日次数（可选）」等参数，结果会随输入实时计算并显示在下方。In the Weight-Based Dosage Calculator (mg/kg, with mL from concentration): Fill in "Weight unit", "Weight (0.1–700 kg)", "Dose per kg (mg/kg)", "Maximum single dose mg (optional)", "Doses per day (optional)"; results are recalculated instantly as you type.
怎么计算？How is it calculated?
单次剂量 = 体重（kg）× 每公斤剂量（mg/kg）；磅会先乘 0.45359237 换成千克。填写最大剂量时取两者较小值；填写浓度时毫升数 = 剂量（mg）÷ 浓度（mg/mL）。Single dose = weight (kg) × dose per kg (mg/kg); pounds are multiplied by 0.45359237 first. With a maximum dose the smaller value is used; with a concentration, volume (mL) = dose (mg) ÷ concentration (mg/mL).
剂量可以填 0 吗？Can the dose be 0?
可以，结果就是 0 mg，页面会注明；负数不允许。Yes — the result is simply 0 mg and the page says so; negative values are not allowed.
体重范围为什么是 0.1–700 kg？Why 0.1–700 kg?
覆盖早产儿到极重成人的范围，超出通常是输错或单位错了（比如把克当成千克）。It covers premature babies to very heavy adults; values outside usually mean a typing or unit mistake (such as grams entered as kilograms).
能用来决定用药吗？Can I use it to decide a dose?
不能。它只帮助核对乘除计算；剂量必须由医生、药师或药品说明书决定。No. It only checks the multiplication and division; doses must come from a clinician, pharmacist or the product label.
能举个计算实例吗？Can you show a worked example?
例如在「按体重计算剂量（mg/kg，含浓度换算毫升）」中填 体重单位 = 磅 lb，体重（0.1–700 kg） = 44，每公斤剂量 mg/kg = 10，每日次数（可选） = 3，药液浓度 mg/mL（可选） = 40，结果区显示：体重（kg）：19.958 kg；按体重计算的单次剂量：199.581 mg；每日总量：598.742 mg（3 × 199.581 mg）；单次用量（毫升）：4.99 mL（浓度 40 mg/mL）；⚠ 仅用于核对算术。实际剂量、上限和给药间隔必须遵循医生处方、药品说明书或药师指导；儿童、肝肾功能不全者尤其要注意。For example, entering Weight unit = Pounds (lb), Weight (0.1–700 kg) = 44, Dose per kg (mg/kg) = 10, Doses per day (optional) = 3, Concentration mg/mL (optional) = 40 in the Weight-Based Dosage Calculator (mg/kg, with mL from concentration) gives: Weight (kg): 19.958 kg; Calculated single dose (weight-based): 199.581 mg; Total per day: 598.742 mg (3 × 199.581 mg); Single dose volume (mL): 4.99 mL (at 40 mg/mL); ⚠ For checking arithmetic only. The actual dose, maximum and interval must follow the…
哪些输入会被检查？Which inputs are validated?
「按体重计算剂量（mg/kg，含浓度换算毫升）」会检查这些输入——「体重（0.1–700 kg）」：必须填写，须大于 0；「每公斤剂量 mg/kg」：所选方式用到时必须填写，不能为负数；「单次最大剂量 mg（可选）」、「药液浓度 mg/mL（可选）」：所选方式用到时必须填写，须大于 0；「每日次数（可选）」：须为 1–24 的整数；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The Weight-Based Dosage Calculator (mg/kg, with mL from concentration) checks its inputs — "Weight (0.1–700 kg)": required, must be greater than 0; "Dose per kg (mg/kg)": required when the chosen option uses it, cannot be negative; "Maximum single dose mg (optional)", "Concentration mg/mL (optional)": required when the chosen option uses it, must be greater than 0; "Doses per day (optional)": must be a whole number from 1 to 24; numbers above 10¹⁵ in absolute value are rejected too. When a value fails, the result area names the problem instead of showing a number.
有哪些选项可以调整？What options can I adjust?
「按体重计算剂量（mg/kg，含浓度换算毫升）」的设置：「体重单位」可选 千克 kg、磅 lb（默认 千克 kg）；「体重（0.1–700 kg）」默认 20；「每公斤剂量 mg/kg」默认 10；「单次最大剂量 mg（可选）」可留空；「每日次数（可选）」可留空；「药液浓度 mg/mL（可选）」可留空。每次生成结果都按当前设置处理。Settings in the Weight-Based Dosage Calculator (mg/kg, with mL from concentration) — "Weight unit": Kilograms (kg), Pounds (lb) (default Kilograms (kg)); "Weight (0.1–700 kg)" default 20; "Dose per kg (mg/kg)" default 10; "Maximum single dose mg (optional)" optional; "Doses per day (optional)" optional; "Concentration mg/mL (optional)" optional. The result always uses the current settings.
