As a medical device, textiles used in operating theatres have to be conform with the requirements of the European Medical Devices Regulation 2017/745.
They are tested according to EN 13795 -- Surgical drapes, gowns and clean air suits, used as medical devices for patients, clinical staff and equipment.

Infective agents can be transmitted during surgical procedures in operating theatres and other medical settings in several ways. One of the important sources are the noses and mouths of the surgical team. When breathing, speaking, coughing or sneezing, a person releases smaller or larger amounts of droplets of secretions from the mucous membranes in the mouth and nose. Those droplets quickly evaporate and leave nuclei suspended in the air. Nuclei can subsequently spread through the air to a susceptible site such as an open operating wound or sterile equipment, or can be inhaled if dimensions

Centexbel is fully equipped to analyse these PPE and is a worldwide acknowledged expert in the evaluation of protective clothing against these infectious diseases.

Centexbel has the knowhow and equipment to assess the barrier properties of textiles, surgical gowns, masks and drapes, against microorganisms and blood.

Determination of the Antimycotic Activity - Agar Diffusion Plate Test

Resistance to bacterial growth

To assess the health and safety risks linked with the skin contact with medical devices, Centexbel examines their toxic effect on the skin (cytotoxicity, irritation, sensitivity,…) according to ISO 10993-5 “Biological evaluation of medical devices – part 5 - cytotoxicity : in vitro methods”

As part of an ongoing pre-normative project, Centexbel is evaluating the possibility of testing surgical masks for their virus barrier. The aim of this project is to demonstrate the filtration efficiency of different types of masks in relation to very small biological structures, the viruses.

Flow cytometry is a laser- or impedance-based, biophysical technology employed in cell counting, cell sorting, bio-marker detection and protein engineering, by suspending cells in a stream of fluid and passing them by an electronic detection apparatus. It allows simultaneous multi-parametric analysis of the physical and chemical characteristics of up to thousands of particles per second.

Methods based on the PCR technique (polymerase chain reaction) can differentiate between wool, cashmere, yak wool and their blends and detect GMO cotton.
