[0002] Expandable sponge is the main packing material for postoperative nasal surgery. Although absorbable hemostatic cotton has been developed, its hemostatic effect is still worse than that of expandable sponge. In addition, both hemostatic cotton and expandable sponge have a common disadvantage, that is, the nasal cavity cannot be ventilated after the packing operation. In order to improve this shortcoming, a breathable expandable sponge is designed.

[0016] Furthermore, the auxiliary mechanism includes:

[0017] A collector for collecting blood left by the core absorption sponge;

[0018] An adhesive ring is connected to the collector and is used to adhere the collecting tank to the inflatable airbag.

[0019] Furthermore, the inner surface of the collector constitutes a collecting groove, and a bonding hole is provided at the center point of the collecting groove for providing the bonding ring to bond to the expanded airbag, wherein the bonding hole is circular and has the same radius and diameter as the expanded airbag.

[0020] Furthermore, the diameter of the ventilation pipe is 5 mm.

The auxiliary mechanism is used to collect blood at the nasal outlet, thereby improving the effectiveness of hemostasis and achieving an improvement in the effectiveness of hemostasis.

Those skilled in the art can adaptively adjust the sizes of the first expansion sponge 2 and the second expansion sponge 11 according to actual conditions, on the premise that the axially symmetrical positional relationship between the first expansion sponge 2 and the second expansion sponge 11 is satisfied.

[0048] Specifically, the length of the core absorption sponge 3 is greater than the length of the first expansion sponge 2 .

[0049] Specifically, the auxiliary mechanism includes:

[0050] The collector 4 is used to collect the blood left by the core absorption sponge 3;

[0051] The adhesive ring 42 is connected to the collector 4 and is used to adhere the collecting tank 41 to the inflatable airbag 10 .
