Furthermore, both ends of the puncturing block are respectively provided with a puncturing tip, the puncturing tips are respectively abutted against the first diaphragm and the second diaphragm, a plurality of connecting pieces are arranged on the puncturing block, and the other ends of the connecting pieces are fixed on the inner wall of the powder cabin.
Furthermore, the first liquid cabin part of the bottle body is of a conical structure, the small opening end of the first liquid cabin is connected with a material conveying pipe, and the outer end of the material conveying pipe is of a closed structure.
Further, the side wall bellows structure of bottle powder cabin.
Further, the first diaphragm and the second diaphragm are made of polyurethane plastic materials.
Further, the bottle body and the puncture block are made of polypropylene materials.
The utility model has the beneficial effects that: the raw materials of the hydrogel are separately placed in a first liquid cabin, a powder cabin and a second liquid cabin in a closed bottle body, and a diaphragm in the bottle body is punctured to mix the raw materials when the hydrogel dressing is used, so that the existing preparation of the hydrogel is realized, the maximum water content of the amorphous hydrogel is reserved, and the using effect of the hydrogel dressing is ensured; simple structure, the using-way is convenient.
