Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

The first embodiment is as follows: as shown in the figure, the medical hemostatic gauze comprises a gauze tape base layer 1, a buffer layer 2, a hemostatic layer 3 and an protective layer 4 which are sequentially connected from bottom to top, wherein a pressing plate 5 and an inflation layer 6 with adjustable thickness are arranged between the gauze tape base layer 1 and the buffer layer 2, the lower end of the inflation layer 6 is fixedly connected with the gauze tape base layer 1, the upper end of the inflation layer 6 is fixedly connected with the lower end of the pressing plate 5, and the upper end of the pressing plate 5 is fixedly connected with the lower end of the buffer layer 2.

In this embodiment, the hemostatic layer 3 is a soluble hemostatic gauze piece.

In this embodiment, the buffer layer 2 is a sponge layer.

In this embodiment, the protective layer 4 is a release paper, and the release paper covers the hemostatic layer 3.

Example two: the rest of the structure is the same as the first embodiment, and the difference lies in that the inflatable layer 6 comprises a gauze 61 and an inflatable air bag 62, an inflation valve 621 and an air release valve 622 are arranged on the inflatable air bag 62, the edge of the gauze 61 is sewn with the gauze tape base layer 1, a containing cavity is formed between the gauze 61 and the gauze tape base layer 1, the inflatable air bag 62 is arranged in the containing cavity, and an opening 11 communicated with the containing cavity is formed in the gauze tape base layer 1. The inflatable air bag 62 may be disposed in a square or strip shape, and when the inflatable air bag 62 is in a strip shape, it is disposed in a spiral or S shape.

In this embodiment, the flip 12 for shielding the opening 11 is disposed on the gauze tape base layer 1, one side of the flip 12 is fixedly connected to the edge of the opening 11, and the edge of the flip 12 is provided with a plurality of auxiliary wings 121 coated with low-sensitivity medical adhesive. When the flaps 121 are bonded to the gauze tape base layer 1, the opening 11 is blocked by the flap 12, and generally three flaps 121 are provided.
