[product performance]
1, dressing liquid absorption: not less than 150%.
2, temperature resistance: placed in the environment of -10 ° C ~ +40 ° C for 24h, there should be no hardening, melting, deformation phenomenon.
3, tensile strength: dressing should be able to withstand 5N static tensile force, lasting 15s, there should be no breakage and deformation.
4. Resistance to negative pressure and airtightness: The drainage conduit (except the cleaning tube) can withstand a negative pressure of 30 kPa for 15 s, and should not be sucked.
5. Dressing biocompatibility: cytotoxicity test: cytotoxicity score no more than 1; delayed type hypersensitivity test: no sensitization reaction; intradermal reaction test: the difference between the average score of the test sample and the solvent control is not more than 1.
6, sterility assurance: the sterilizing process should be sterilized by a confirmed sterilization process.
[Usage]
1. Thorough debridement and hemostasis.
2. In the case of cleaning, open the sealed packaging bag, trim the drainage dressing into a shape consistent with the size of the wound/cavity, cover it on the wound surface or insert it into the wound cavity, and fix the number of needles on the edge intermittently, and put the drainage dressing on the dressing. The drainage tube is taken out from the normal subcutaneous tissue about 5 cm away from the wound/cavity or by the "membrane method", using straight through
Or the tee merges the multiple drainage tubes into one or two outlets.
3, closed wound / cavity: the skin around the wound surface is clean and dry, with the adhesive film to seal the entire wound to the edge of the wound about 3cm ~ 4cm range.
4. Connect the drainage tube to the negative pressure source, adjust the negative pressure to -50mmHg -225mmHg (0.017MPa~0.026MPa), shrink the dressing material, and have the liquid drainage. After 3-7 days of continuous drainage, take the drainage dressing and observe. If the wound is not clean, repeat the drainage dressing until the wound is clean.
