PVA Foam | Nasal Foam
Highly Absorbent PVA Nasal Dressing for Effective Post-Operative Hemostasis
Introduction：
Our PVA Foam (Nasal Foam) is a specialized medical-grade dressing designed for superior hemorrhage control and cavity support following nasal or sinus surgery. Crafted from biocompatible, porous polyvinyl alcohol, the foam rapidly absorbs exudate and blood, expanding gently to exert balanced, therapeutic pressure on the nasal mucosa. This stabilization is crucial for effective hemostasis and provides a clean, protected environment that minimizes the risk of post-operative infection and promotes rapid healing in the delicate nasal passages.
Features：
Rapid Expansion: Upon contact with fluids, the compressed foam expands to fit the anatomical contours of the nasal cavity, providing immediate and consistent compression for hemostasis.
Biocompatible Material: Made from medical-grade, low-linting PVA that is non-toxic and hypoallergenic, ensuring it is safe for delicate mucosal tissues.
High-Capacity Absorption: Engineered with an interconnected pore structure to maximize fluid uptake, keeping the nasal cavity dry and clean during recovery.
Atraumatic Removal: The foam's soft texture and structure minimize adherence to healing tissues, ensuring a comfortable, pain-free removal process.
Anatomical Conformability: Perfectly adapts to the complex structure of the nasal passage, providing uniform pressure to prevent bleeding without causing discomfort to the patient.
Product Performance：
Low sensitization:The fibrous structure of the gauze is low-allergen and helps control bleeding by promoting rapid blood coagulation, forming a protective clot to achieve hemostasis.
High Absorption:The fibrous structure of the gauze can absorb more than ten times its own weight in liquid, quickly absorbing fluids from the surgical area and preventing fluid accumulation.
Soft and protective to tissue:The fibrous structure of the gauze can absorb more than ten times its own weight in liquid, quickly absorbing fluids from the surgical area and preventing fluid accumulation.
Working Principle：
Absorbs wound secretions, promotes wound drying, and helps accelerate the healing process.
The gauze provides physical isolation to keep the wound clean and prevent microbial invasion.
