In order to achieve the above object, the utility model adopts the following technical solutions:

A nostril dilator, which includes an expansion tube placed in the posterior nasal cavity for dilating the posterior nostril, at least one ventilation tube is arranged at one end of the expansion tube close to the front nostril, and the inner cavity of the ventilation tube It communicates with the inner cavity of the expansion tube, and the ventilation tube penetrates outward from the posterior nasal cavity into the nasal cavity. Behind the nostrils is used to secure the dilation tube in the posterior nasal cavity.

Preferably, there are two ventilation tubes, the interval between the two ventilation tubes is greater than or equal to the thickness of the nasal septum, and a tie is provided at the outer ends of the two ventilation tubes, and the two tie straps After piercing through the left and right nostrils, they are connected or glued on the outside of the nasal septum to fix the nostril dilator in the nasal cavity.

Preferably, the tie is a tie with a flat structure.

Preferably, the tether and the ventilation pipe are integrally structured.

Preferably, the tether and the ventilation tube are integrally injection-molded from silicone.

Preferably, the expansion tube is a silicone tube.

Preferably, the ventilation tube is detachably connected to the end of the expansion tube or the ventilation tube and the expansion tube are integrally injection molded.

Preferably, the tube wall at the outer end of the ventilation tube and the tube wall of the expansion tube are arranged at an angle or in an arc.

Preferably, the dilation tube and the vent tube are flexible tubes.

The beneficial effects of the utility model:

The nostril dilator of the utility model can be placed in the posterior nasal cavity for a long time, up to 3 months, and the patient's nasal cavity can be ventilated freely after being placed, thereby promoting recovery. Since the device can be placed in the nasal cavity for a long time, the wound is always in a state of expansion during postoperative recovery, avoiding the narrowing or even occlusion of the posterior nostril caused by scar contracture during wound healing, and promoting wound healing and recovery. Ensure smooth breathing.

Detailed ways

Referring to Fig. 1, a kind of nostril dilator, it comprises the expansion tube 1 that is placed in the posterior nasal cavity and is used for dilating the posterior nostril, one end of the expansion tube 1 near the front nostril is provided with at least one ventilation tube 2, The inner cavity of the ventilation tube 2 communicates with the inner cavity of the expansion tube 1, and the ventilation tube 2 penetrates outward from the posterior nasal cavity into the nasal cavity, and the outer end of the ventilation tube 2 is provided with a frenulum 3. The frenulum 3 passes through the nasal cavity outwards from the posterior nasal cavity, and is used to fix the expansion tube 1 in the posterior nasal cavity behind the anterior nostril. The said ventilation tube 2 of the present embodiment is provided with two, and the space between two described ventilation tubes 2 is greater than or equal to the thickness of nasal septum, and the outer end of two described ventilation tubes 2 is respectively provided with a frenulum 3, two After the frenulum 3 passes through the left and right nostrils, it is connected or glued to the outside of the nasal septum to fix the nostril dilator in the nasal cavity. The nostril dilator of the utility model can be placed in the posterior nasal cavity for a long time, up to 3 months, and the patient's nasal cavity can be ventilated freely after being placed, thereby promoting recovery. Since the device can be placed in the nasal cavity for a long time, the wound is always in a state of expansion during postoperative recovery, avoiding the narrowing or even occlusion of the posterior nasal cavity caused by scar contracture during wound healing, and promoting wound healing and recovery. Ensure smooth breathing.

The lace 3 of this embodiment is a lace with a flat structure, the lace and the ventilation tube 2 are integrally formed, the lace and the ventilation tube 2 are integrally injection-molded by silica gel, and the expansion Tube 1 also adopts a silicone tube, so that the inside of the device can be guaranteed to have a smooth and soft silicone surface, which can effectively prevent scabs and retention of secretions in the tube.

The ventilation tube 2 in this embodiment is detachably connected to the end of the expansion tube 1 , and in other embodiments, the ventilation tube 2 and the expansion tube 1 can also be integrally injection-molded with silicone material. The pipe wall at the outer end of the vent pipe 2 and the pipe wall of the expansion pipe 1 are arranged in an angle or an arc. Referring to FIG. The structure of the posterior nostril and nasal cavity is matched to make the structure of the dilator more suitable for the structure of the posterior nostril and nasal cavity, reduce the foreign body sensation, ensure smooth ventilation, and make the patient comfortable to wear.

The expansion tube 1 and the ventilation tube 2 in this embodiment are flexible tubes made of silicone material. In other embodiments, they can also be made of other flexible materials, as long as they can meet the technical requirements of the utility model.

The above-mentioned specific implementation is only a detailed explanation of the technical solution of the utility model, and the utility model is not limited to the above-mentioned embodiments.
