Title BIOABSORBABLE SHEET OR FILM UPDATE_EN
Abstract The present invention relates to a bioabsorbable sheet or film which comprises a composition containing phosphorylated pullulan. The bioabsorbable sheet or film according to the present invention can be used suitably in the field of medicine, for example, as a medical adhesive agent that is to be adhered onto a tissue in a body, e.g., an organ and a blood vessel, during a surgical operation.
Scope of claims [claim1]
1. It consists of the composition which contains the phosphorylation pullulan, the seat or the film of organism absorptivity.
[claim2]
2. The composition furthermore including the plasticizer, it becomes, the seat or the film of claim 1 statement.
[claim3]
3. The kind where the plasticizer is chosen from the glycerine and polyethylene glycol is included at least, in claim 2 the seat or the film of statement.
[claim4]
4. The composition furthermore containing the biological activity medicine, it becomes, claim 1-3 in each case the seat or the film of statement.
[claim5]
5. It is supported in the backing seat, claim 1-4 in each case the seat or the film of statement.
[claim6]
6. It is the cladding material of the wounding section, the deficiency section or the fragile section in the internal organs or organizing of in vivo, claim 1-5 in each case the seat or the film of statement.
[claim7]
7. It is the leakage of the playback of in vivo organization or reconstruction material or prevention of the diffusion material or the fixed material, claim 1-5 in each case the seat or the film of statement.
[claim8]
8. It is the leakage of the biological activity medicine or prevention of the diffusion material, claim 1-5 in each case the seat or the film of statement.
[claim9]
9. Chemistry it consists of the composition which contains the phosphorylation pullulan which is decorated, the seat or the film of organism absorptivity.
[claim10]
10. Chemical decoration, it is the chemical decoration which you can do the etherification medicine, the esterification medicine and the acetalized medicine, isoshianeto, isothiocyanate, karubamoirukurorido and chiokarubamoirukurorido, the silane coupling medicine, chloridation sulfonyl and the sulfonic acid anhydride, making use of the chemical compound which is chosen from the group which consists of the polymer, and the building a bridge medicine high-molecular, the seat or the film of claim 9 statement.
[claim11]
11. Chemical decoration is surface hydrophobic conversion of the phosphorylation pullulan, claim the seat or the film of 9 or 10 statements.
[claim12]
12. It is something where chemical decoration introduces building a bridge structure into the phosphorylation pullulan, claim the seat or the film of 9 or 10 statements.
[claim13]
13. The composition furthermore containing the biological activity medicine, it becomes, claim 9-12 in each case the seat or the film of statement.
[claim14]
14. It is something where controlled release characteristic of the biological activity medicine is controlled, the seat or the film of claim 13 statement.
[claim15]
15. It is the double layer system which laminates other layer, claim 1-14 in each case the seat or the film of statement.
