EN 13795 – Surgical Gowns Barrier Performance Test
The EN 13795 standard specifies the method for determining the barrier properties of surgical gowns used in healthcare settings. This test is critical to ensure that surgical gowns provide an effective physical and microbial barrier between the patient, surgical staff, and the environment. Understanding and implementing this standard is essential for quality managers, compliance officers, R&D engineers, and procurement teams involved in medical device manufacturing.
The primary focus of EN 13795 is to evaluate the ability of surgical gowns to resist penetration by microorganisms, blood, and other body fluids under controlled conditions. This ensures that healthcare workers are protected during surgical procedures, thereby reducing the risk of cross-infection.
EN 13795 defines a series of tests that can be performed on surgical gowns to assess their barrier properties. These include:
- Blood spatter resistance
- Fluid resistance
- Virus retention efficiency
- Microbial barrier performance
The methodology for each test is detailed in the standard, and it requires specific apparatus and materials to ensure accurate testing. The tests are conducted under controlled environmental conditions to simulate real-world scenarios as closely as possible.
This section provides a comprehensive overview of the EN 13795 standard, its importance in the healthcare sector, and how it is applied in practice. Understanding this standard is crucial for ensuring that surgical gowns meet the highest standards of safety and effectiveness.
| Test | Description | Methodology |
|---|---|---|
| Blood Spatter Resistance | Evaluates the gown's ability to resist penetration by simulated blood spatters. | The test involves spraying a controlled amount of red dye onto the fabric and assessing the spread and retention of the dye on the material. |
| Fluid Resistance | Determines if the gown can withstand the passage of water under pressure, simulating exposure to fluids during surgery. | The test uses a hydraulic system to apply water at high pressure for a specified duration and measures any leakage through the fabric. |
| Virus Retention Efficiency | Assesses how effectively the gown can retain viruses, ensuring that they do not pass through the material. | The test involves exposing the gown to a solution containing a virus and then analyzing the remaining viral content after exposure. |
| Microbial Barrier Performance | Evaluates the gown's ability to prevent microbial penetration under controlled conditions. | This test typically involves placing microorganisms on one side of the fabric and assessing their presence on the other side after a specified period. |
The results of these tests are critical for ensuring that surgical gowns meet the necessary safety standards. The tests provide quantitative data on the gown's barrier properties, which can be used to make informed decisions about procurement and quality control.
Understanding EN 13795 is important not only for compliance but also for innovation in medical device design. By adhering to this standard, manufacturers can ensure that their products are safe and effective, thereby contributing to the overall safety of healthcare workers and patients.
Scope and Methodology
The scope of EN 13795 is limited to surgical gowns used in medical procedures. The standard specifies the methods for evaluating the barrier properties of these gowns, focusing on their ability to resist penetration by microorganisms, blood, and other body fluids.
- Apparatus:
- Blood spatter simulator
- Fluid resistance tester
- Virus retention efficiency chamber
- Microbial barrier performance test apparatus
- Materials:
- Surgical gown samples
- Blood simulant
- Pure water for fluid resistance tests
- Virus solution
- Microbial test organisms
The methodology involves several steps to ensure accurate and reliable testing. First, the gowns are prepared according to the standard's specifications. Then, each test is conducted under controlled conditions, using the specified apparatus and materials.
For example, in the blood spatter resistance test, a controlled amount of red dye is sprayed onto the fabric, and the spread and retention of the dye are measured. In the fluid resistance test, water is applied at high pressure to simulate exposure to fluids during surgery, and any leakage through the fabric is carefully measured.
The results of these tests provide quantitative data on the gown's barrier properties, which can be used to make informed decisions about procurement and quality control. These tests are crucial for ensuring that surgical gowns meet the necessary safety standards, thereby contributing to the overall safety of healthcare workers and patients.
