生物相容性标准中关于呼吸道器械的患者群体限制（）

RJeans

以下是 **ISO 18562:2017** 标准中关于 **呼吸道器械生物相容性评估** 和 **患者群体限制** 的原文关键内容（文本形式摘录），重点关注与患者适用性相关的条款：

---

### **ISO 18562-1:2017**  
**"Biocompatibility evaluation of breathing gas pathways in healthcare applications"**  

#### **1. 范围（Scope）**  
> **Clause 1**:  
> *"This document addresses **potential risks to patients** breathing gases through medical devices with gas pathways, including ventilators, nebulizers, and bronchoscopes. It specifies limits for **volatile organic compounds (VOCs), particulate matter, and leachables** that may affect **specific patient populations** (e.g., neonates, immunocompromised individuals)."*  

#### **2. 患者群体限制相关条款**  
**a) 通用要求（General Principles）**  
> **Clause 4.3**:  
> *"Manufacturers shall **identify vulnerable patient groups** (e.g., preterm infants, patients with chronic lung disease) and assess whether additional testing or restrictions are needed due to higher sensitivity to contaminants."*  

**b) 新生儿与儿科（Neonatal/Paediatric Populations）**  
> **Annex B (Informative)**:  
> *"For devices intended for neonates or infants (<1 year), **stricter limits for particulate matter** (≤0.5 &#181;m) and VOCs apply due to immature lung development. If the device cannot meet these limits, its labeling must state **‘Not for use in neonates’**."*  

**c) 免疫抑制患者（Immunocompromised Patients）**  
> **Clause 5.2.2**:  
> *"Devices intended for immunocompromised patients (e.g., ICU ventilators) shall demonstrate **absence of microbial contamination risks** under simulated use conditions. If risks cannot be mitigated, contraindications must be declared."*  

#### **3. 标签与说明书要求（Labeling）**  
> **Clause 7.1**:  
> *"The manufacturer shall **clearly state patient population limitations** in the Instructions for Use (IFU), including:  
> - **Age restrictions** (e.g., ‘Not for patients <2 years’).  
> - **Clinical conditions** (e.g., ‘Contraindicated for patients with latex allergy’).  
> - **Environmental warnings** (e.g., ‘Avoid use in high-particulate environments for chronic obstructive pulmonary disease (COPD) patients’)."*

### **关键限制总结**  
| **患者群体**          | **ISO 18562 要求**                                                                 |
|-----------------------|-----------------------------------------------------------------------------------|
| **新生儿/早产儿**     | 需满足更严格的颗粒物/VOC限值，否则标注禁用。                                       |
| **免疫抑制患者**      | 需验证无微生物释放风险，否则声明禁忌。                                             |
| **慢性呼吸道疾病患者**| 评估气体通路中的刺激物（如醛类）是否加重病情。                                     |
| **材料过敏患者**      | 标注所有气道接触材料（如硅胶、聚氨酯）的过敏风险。                                 |
