Patent ID: 7427607

Claim:
A method for administering a biopolymer having hemostatic or adhesion preventing functions, comprising the steps of: fluidizing fine particles of the biopolymer having hemostatic or adhesion preventing functions with a gas to prepare a homogenous mixed-phase fluid; transferring the mixed-phase fluid through at least one micro-tube by flowing the gas; mixing a liquid with the mixed-phase fluid, the liquid being selected from the group consisting of a saline solution, an infusion solution, an aqueous solution of a drug and an aqueous solution of a biopolymer; the liquid being injected into the micro-tube thorough at least one inner tube so that the liquid is mixed with the mixed-phase fluid, wherein the inner tube is configured to be within the micro-tube; spraying the mixed liquid and the mixed-phase fluid toward a target site from an open tip of the micro-tube; wherein the mixed liquid and the mixed-phase fluid become a gel compound after the liquid and the mixed-phase fluid are mixed; whereby the fine particles of the biopolymer are capable of being sprayed as a gel compound toward the targct site to provide a seal upon the target site.
