Blood Penetration Resistance Testing in Medical Textiles
The testing of blood penetration resistance in medical textiles is a critical aspect of ensuring patient safety and compliance with international standards. This service involves evaluating how well medical textiles can withstand the passage of blood, which is essential for surgical gowns, drapes, and other protective apparel used during medical procedures.
Textiles that fail to provide adequate protection against blood penetration can lead to potential infections or contamination risks in healthcare settings. Therefore, it is imperative that these materials undergo rigorous testing to ensure they meet the required standards.
The primary focus of this service is on the resistance provided by textiles when exposed to simulated blood under specific pressure conditions. The testing typically involves applying a controlled amount of blood (or an equivalent fluid) at a defined pressure and time period, then assessing whether any leakage occurs through the material. Compliance with relevant standards such as ISO 16602:2018 ensures that products are suitable for use in medical environments.
This service also includes the preparation of samples according to international guidelines, ensuring accurate testing results. Afterward, detailed reports are generated summarizing test outcomes and comparing them against set criteria. These reports help clients understand their product's performance relative to industry benchmarks and aid in decision-making processes related to quality improvements or regulatory submissions.
The importance of this service cannot be overstated given its role in safeguarding patients' health by minimizing the risk of cross-contamination during surgical procedures. By partnering with a reputable lab like Eurolab, organizations can ensure they receive accurate, reliable data that supports informed decisions about material selection and process optimization.
Scope and Methodology
The scope of blood penetration resistance testing covers the evaluation of medical textiles' ability to prevent the passage of blood or other bodily fluids through their surface. This includes both flat fabrics and non-woven materials used in surgical gowns, drapes, and similar applications.
| Test Parameters | Description |
|---|---|
| Pressure Applied | The amount of pressure applied to the material during testing is crucial as it simulates real-world conditions encountered during medical procedures. Typical pressures range from 0.5 bar up to 2 bar. |
| Blood Equivalent Fluid | A solution designed to mimic the properties of blood, such as viscosity and pH level, is used for testing purposes. This ensures consistent results across different types of textiles. |
| Duration of Exposure | The duration for which the fluid is applied varies depending on the specific application. For instance, surgical gowns may require a longer exposure time compared to disposable drapes due to varying usage scenarios. |
The methodology followed aligns with internationally recognized standards such as ISO 16602:2018 and ASTM F1670-14. These guidelines provide clear instructions on specimen preparation, testing procedures, and evaluation criteria to ensure consistent and repeatable results.
To prepare specimens for testing, Eurolab adheres strictly to specified dimensions and weights outlined in the relevant standard documents. Specimens are then carefully cut from larger fabric rolls using precise measurements to maintain accuracy throughout the testing process.
During testing, each specimen is placed on a carrier device designed specifically for this type of test. The carrier ensures that the sample remains flat during application of pressure and exposure time. After applying the specified amount of blood equivalent fluid at the designated pressure level for the required duration, the sample is inspected visually for any signs of leakage.
The visual inspection is followed by a quantitative evaluation where areas suspected to have leaked are measured using calibrated rulers or digital imaging techniques. This step provides precise data on the extent and location of any breaches in the fabric integrity.
Based on these observations, Eurolab assigns numerical scores representing the degree of blood penetration resistance exhibited by each specimen. These scores help clients compare their products against industry norms and identify areas for improvement or innovation.

Use Cases and Application Examples
- Surgical Gowns: These are essential items worn by surgeons during operations. They must be able to withstand high-pressure applications of blood without compromising sterility or integrity.
- Medical Drapes: Used to cover operating tables, these drapes need to maintain their structural integrity even after prolonged exposure to blood and other bodily fluids.
- Infection Control Garments: Designed for use in hospitals where strict hygiene protocols are enforced, such garments should exhibit superior resistance against blood penetration to prevent cross-contamination.
- Dental Lab Coats: Worn by dental professionals during procedures involving blood or saliva contact, these coats require robust protection capabilities to safeguard both the wearer and patients from potential contaminants.
| Use Case | Description |
|---|---|
| Surgical Gowns | These are typically made from breathable yet durable materials like polyethylene or polyester blends. They come in various sizes and styles catering to different surgical procedures. |
| Medical Drapes | Draperies used during surgeries often consist of multi-layered structures incorporating layers of absorbent material sandwiched between outer protective films. |
| Infection Control Garments | For this application, non-woven materials like spunbond or meltblown offer excellent blood barrier properties combined with breathability features allowing comfortable use over extended periods. |
| Dental Lab Coats | These lightweight yet strong coats are usually composed of woven cotton or similar fabrics reinforced at strategic points to enhance their resistance against punctures and tears. |
In addition to these examples, Eurolab also conducts tests on other types of medical textiles including bandages, wound dressings, isolation gowns, and surgical masks. Our comprehensive approach ensures that all aspects of textile performance are thoroughly examined before certification or approval is granted.
