A sinus irrigation and drainage device, as shown in Fig. 1 and Fig. 2, includes a device body, and a flushing tube 1 and a plurality of drainage tubes 2 are arranged inside the device body.

The outer side of the device body is provided with a sponge auxiliary material 3, and the sponge auxiliary material 3 is a polyurethane sponge, which is closely attached to the outer side of the device body.

The flushing tube 1 is arranged in the center of the device body, and the drainage tube 2 is relatively independent and evenly distributed around the flushing tube 1; the drainage tube 2 includes an upper drainage tube 2-1, a middle drainage tube 2-2 and a lower drainage tube 2-3, which are distributed on the concentric circle with the flushing pipe 1 as the center. The number of the upper drainage tube 2-1, the middle drainage tube 2-2 and the lower drainage tube 2-3 is eight respectively, which are distributed on the concentric circles centered on the flushing tube 1, as shown in FIG. 2 .

The drainage tube 2 is provided with several drainage holes 4, which are arranged along the axial direction of the drainage tube 2, and the number of drainage holes 4 on each drainage tube 2 is five pieces.

The drainage hole 4 includes an upper drainage hole 4-1, a middle drainage hole 4-2 and a lower drainage hole 4-3, as shown in FIG. 3 . The end of the drainage tube 2 is provided with a drainage hole collection hole, which includes the upper drainage hole collection hole 9-1, the middle drainage hole collection hole 9-2 and the lower drainage hole collection hole 9-3, which are distributed in the flushing pipe 1. on the concentric circle at the center, as shown in Figure 2.

The sinus flushing and drainage device also includes a flow meter 6, one end of which is connected to the drainage tube 2 through an adapter tube 5 (as shown in Figure 3 ), and the other end is connected to the suction tube 7, which is collectively connected to the suction main pipe 8, as shown in Figure 4, the transfer pipe 5 is also provided with a valve. The flow meter 6 can detect the amount of liquid drained from each drainage tube 2 , that is, the total amount of drainage fluid in each area. Determine whether there is sponge blockage or excessive drainage in a certain area based on the total amount of drainage fluid, and further determine whether the drainage device has failed or whether there is too much pus in the sinus corresponding to the area based on the above data.

After the device is implanted in the sinus tract, the entrance of the sinus tract is closed through a translucent membrane, thereby forming an internal circulation of closed flushing and drainage in the sinus tract. The flow meter 6 can detect the amount of liquid drained from each drainage tube 2 , that is, the total amount of drainage fluid in each area.

During treatment, the sinus tract is temporarily closed to prevent the entry of external bacteria into the sinus to form mixed infections. The aspirated drainage fluid can be used for qualitative culture to clarify bacteria and add sensitive antibiotics; the suction effect of negative pressure can promote the formation of fresh granulation tissue at the micropores on the inner surface of the sinus through the traction stimulation of the suction, laying a solid foundation for the healing of deep tissues.
