The invention discloses a medical fixing adhesive tape. The medical fixing adhesive tape includes a bottom silica gel layer, and a polyurethane film layer arranged above the silica gel layer in a covering manner, wherein a meshed connecting layer 3 is further arranged between the silica gel layer and the polyurethane film layer, so that silica gel can seep into the gaps formed by the meshed connecting layer, and the silica gel layer can further form an integral structure framed by the meshed connecting layer, which achieves low possibility of local silica gel falling, and further enhances the strength of the tape and the adhesion fastness of the tape and the skin. The medical fixing adhesive tape has the following benefits: 1, the breathability is high, so as to avoid the whitening of the soaked skin at a wound and inflammation caused by bacterial growth, and facilitate rapid wound healing; 2, the tape is non-irritating and non-harmful to the skin, and can be comfortably applied and gently removed without pains; 3, the application effect is good, that is, the tape is unlikely to fall off and particularly achieves low possibility of local falling of the silica gel layer, and the tape has a high overall fastness and a long service life.
