Introduction
Medical institution staff face a relatively high risk of pathogen exposure in scenarios such as the treatment, prevention and control of infectious disease patients, and infection control. They need to wear corresponding personal biological protective equipment to provide physical barriers, in order to minimize the risk of being infected with infectious substances from patients, environment, and other aspects. Biological protective clothing that can provide physical protection for medical personnel is managed according to Class II medical devices in China. Therefore, this mandatory national standard is formulated as a technical document that can be used as a basis for the production, inspection, supervision, and sampling of disposable protective clothing for medical use.
The manufacturers of disposable protective clothing for medical use are responsible for testing the products they produce in accordance with the requirements of this document. The performance indexes mainly include material physical performance, material biological protection performance, comfort, etc. Considering the practical use of medical scenarios and management requirements related to medical devices, this document also sets requirements for flammability, antistatic property, biocompatibility, microbial load, and ethylene oxide residue. In the process of formulating this document, for the setting of performance indexes for disposable protective clothing products, the first consideration is to meet the basic requirements of biological protection, while the actual use in medical scenarios. For applications beyond the scope specified in this document, if infectious pathogen protection is required in non-medical scenarios, users are responsible for conducting risk assessments and studying the feasibility of using the products applicable to this document.
This document specifies the minimum requirements for product performance. The manufacturers can develop and design products with higher performance levels based on the actual needs of users and the temperature and humidity usage conditions in different regions and climates to meet market needs. In addition, the manufacturers shall also consider ergonomics when designing clothing, optimize the structural design of protective clothing to improve the overall protective effect of protective clothing, and consider comfort (water-vapour transmission rate, moisture resistance, breathability, etc.). The overall protective performance can be tested and evaluated according to the methods specified in other relevant standards as needed.
