The invention discloses
chitosan gelatin having physiological response properties and an application of the
chitosan gelatin to prevention adhesion in
uterine cavity, and belongs to the technical field of
pharmaceutics. The
chitosan gelatin is prepared through the steps of adding
active components having functions of stopping bleeding, resisting
bacteria, promoting healing and the like to a non-chemical crosslinking thermo-sensitive
bacteria-
free water gelatin substrate, wherein under the room-temperature condition, the gelatin being favorable in flowing properties and being in the state of
sol is convenient for medication in the
uterine cavity, at the
physiology temperature of wombs, the gelatin rapidly gelate and is solidified, physical isolation on wound parts after an intrauterine operation is completed, adhesion is avoided, besides, the functions of a biologicalactivity material are exerted, and quick healing of wound parts is promoted. After the wombs are restored, under the physiological action of proliferation and
secretion,
corrosion and
erosion of the gelatin are completed, the gelatin is discharged outside the bodies along with
secretion, and human intervention is not needed. The gelatin has the advantages of being simple to apply, capable of predicting effects, free from secondary intervene and the like, and can be used for preventing adhesion after intrauterine operations.
