Product Description

Medical Filter 99.999% Filter Effect Durability Wood Pulp 90g/m2 Heat and Moisture Exchange Filter Paper

Product Description:

The Absorbent Filter Paper is a pivotal component in the manufacturing of medical devices, particularly as a Ventilator HMEF (Heat and Moisture Exchanger Filter) material. Designed to meet the rigorous demands of medical applications, this product is constructed from high-quality wood pulp, ensuring a natural and reliable base for absorption. The purity of the wood pulp used in the filter paper plays a critical role in its performance, offering an optimal balance of strength, filtration efficiency, and absorbency.

This product is classified under Medical Materials & Accessories, highlighting its application in the medical field. It is commonly used in the production of ventilator circuits as part of the Heat and Moisture Exchanger (HME) system. The HME system serves a crucial function in mechanical ventilation by conditioning the air, adding heat and moisture to the gas delivered to the patient, thus mimicking the natural respiratory functions of the nose and upper airways.

The Absorbent Filter Paper adheres to the safety standard GB/T18830-2009, which is a testament to its compliance with national regulations for hygiene and safety in medical materials. This standard ensures that the filter paper has been rigorously tested and meets specific criteria for efficacy and safety in healthcare settings. Adherence to such standards is paramount in the production of materials destined for use in devices like ventilators, which are critical for patient care in various medical situations, including intensive care and anesthetic procedures.

Furthermore, the product comes with Quality Certification MSDS (Material Safety Data Sheet), which provides detailed information on the properties of the filter paper, including chemical composition, potential hazards, handling, storage, and disposal. The MSDS is an essential document that outlines how users should interact with the material safely, making it an integral part of workplace safety and compliance in medical facilities. This certification ensures that all parties involved in the handling of the Absorbent Filter Paper are fully informed about the product's specifications and safety measures.

The Absorbent Filter Paper is available in two levels of thickness and absorbency, allowing for customization according to the specific requirements of the Heat and Moisture Exchanger in various ventilator models. Whether for an intensive care unit ventilator, an anesthetic workstation, or a portable ventilator, the adaptability of the filter paper's levels ensures that the HMEF material can be tailored to provide the best patient care possible. Different levels offer versatility in usage, with each level being optimized for a particular balance of resistance, moisture output, and filtration performance.

As a Ventilator HMEF material, the Absorbent Filter Paper plays a critical role in ensuring the functionality and efficacy of the ventilator in providing respiratory support. It is designed to retain moisture and warmth while preventing the passage of bacteria and viruses, thereby reducing the risk of infection and ensuring a sterile pathway for the ventilated air. Its efficient moisture retention helps to prevent the drying of patient airways, a common issue during mechanical ventilation, making it an essential component for patient comfort and health.

Ultimately, the Absorbent Filter Paper stands out for its exceptional quality, safety, and versatility. It is a product that merges innovation with reliability, providing the medical industry with a material that assures the safety and comfort of patients requiring mechanical ventilation. Its conformity to standards and certifications emphasizes its suitability for critical medical applications, making it an indispensable material for Ventilator HMEF systems.
