Abstract
A sponge including one or more hemostatic agents and one or more binding agents. At least one of the hemostatic agents is a pregelatinized potato starch. The collective percentage by weight of the one or more hemostatic agents is within the range of approximately one eighth to approximately sixteen times as great as the collective percentage by weight of the one or more binding agents.
Claims19
A sponge, comprising:
- one or more hemostatic agents, wherein at least one of the hemostatic agents comprises a pregelatinized potato starch;
- and
- one or more binding agents, wherein the collective percentage by weight of the one or more hemostatic agents is within the range of approximately one eighth to approximately sixteen times as great as the collective percentage by weight of the one or more binding agents.
A sponge, comprising:
- one or more hemostatic agents, wherein at least one of the hemostatic agents comprises a pregelatinized potato starch;
- one or more binding agents selected from the group consisting of polyethylene glycol, glycerol, sorbitol, erythritol, propylene glycol, pentaerythritol, glycerol esters, hydroxypropylmethyl cellulose (HPMC), hydroxypropylcellulose (HPC), hydroxypropylethylcellulose (HPEC), xanthum gum, and guar gum;
- and
- a clotting accelerator selected from calcium chloride, prothrombin, and vitamin K;
- wherein the collective percentage by weight of the one or more binding agents is within the range of approximately one quarter to approximately equal to the collective percentage by weight of the one or more hemostatic agents.
