The biocompatibility of Sugi® medical grade sponges has been certified according to ISO 10993-5, 10993-10, and 10993-18, and can be seen by a summary of the tests performed.
- Practice-proven: In more than 45 years of use in microsurgery, ophthalmology, and ENT surgery, there have been no known tissue reactions to the material.
Due to special manufacturing and processing methods, the cotton fibers are firmly embedded in the material, making it virtually lint-free.
Practice-proven: This property makes it the preferred cellulose material in the field of eye and ENT surgery.
The high tensile strength (tear strength) is an expression of the firm bond between the cotton fibers and the regenerated cellulose: >50 N (strips 19 x 81 mm = material in full thickness).
- Practice-proven: This value of Sugi® medical grade sponge material has only been achieved through experience, special production techniques, and recipes, and is, according to current knowledge, unique in the field of cellulose sponge materials.
Sugi® medical grade sponge material is compatible with the sterilization methods of ETO gas and gamma rays. Due to the physical properties of cellulose, the material begins to degrade at a continuous temperature of approx. 110 °C. Sterilization in an autoclave is therefore not recommended.
The Sugi® medical grade sponges are stable in a wide range of chemicals and solutions. A stability table provides information about the resistance of the material to different chemicals that have been analyzed.
- Practice-proven: The disinfection of IV connections or similar applications is very critical in the treatment of hospital infections. Sugi® medical grade sponges display excellent stability in concentrated alcoholic solutions and can therefore be used as a reservoir for this purpose.
Sugi® medical grade sponges are manufactured and tested according to the Ph. Eur. and/or DAB 10. These tests have been designed to qualify the material within the auspices of a medical device manufacturer. Sugi® medical grade sponges are not bleached. TAPPI classification: TAPPI T213, T437, Size <0.15 mm², quantity/m² <250. Furthermore, the material is processed in a clean room environment of ISO Class 8 with bioburden levels of < 50 CFU/g.
