Description

Technical Field

[0001] This application relates to the field of medical devices, specifically to a posterior nasal packing device with an airway. Background Technology

[0002] Nasopharyngeal surgery, especially after the removal of nasopharyngeal necrosis and subsequent flap repair, requires local packing. However, the packing material easily slips from the nasopharynx into the oropharynx, affecting the packing and surgical outcomes, increasing postoperative discomfort, and reducing treatment adherence. Currently, there is no effective solution. Furthermore, the available packing materials and devices for stopping nasopharyngeal bleeding are limited. Traditional posterior nasal plugs cause significant pain during and after packing. Balloons or water-filled balloons used for packing are not perfectly shaped for the nasopharynx and require monitoring during swallowing, resulting in poor packing effectiveness. Additionally, patients often cannot breathe through the nose after packing. Utility Model Content

[0003] The purpose of this application is to provide a posterior nasal packing device with an airway to solve the technical problems described in the background art.

[0004] A posterior nasal packing device with a ventilation tube includes: an insertion blind end, a ventilation tube body, and a packing bag body; the packing bag body is fixedly disposed at the insertion blind end, covering three-quarters of the surface of the insertion blind end; a ventilation hole is provided in the area of ​​the insertion blind end that is not covered by the packing bag body, and the rear end of the insertion blind end is connected to the ventilation tube body.

[0005] Furthermore, the posterior nasal packing device with an airway tube also includes: a limiting and fixing part; one end of the limiting and fixing part is fixedly installed at the rear end of the airway tube body, and the other end is fixedly installed with an airway opening section.

[0006] Furthermore, at least three ventilation holes are opened in the area of ​​the blind end that is not covered by the packing sac.

[0007] Furthermore, the rear end of the packing capsule is connected to and fixed with the packing tube.

[0008] Furthermore, a tampon containing a tampon is provided inside the ventilator, and the tampon is inserted into the tampon containing the tampon.

[0009] Furthermore, a filling interface is fixedly installed at the rear end of the filling tube; the filling interface is connected to the inflation / deflation device or the water filling / pumping device.

[0010] Furthermore, the outside of the ventilation tube is marked with graduations.

[0011] Compared with the prior art, the advantages and positive effects of this application are as follows: the posterior nasal packing device with a ventilator enters through the nasal cavity or inferior nasal meatus, the packing bag packs the posterior nasal cavity, and the ventilator delivers air to the posterior end of the patient's nasal cavity through the ventilator at the blind end, reducing the patient's pain during and after packing. The blind end is adapted to the shape of the nasopharynx and is fixed by the packing bag, making it less likely to move with swallowing, allowing the patient to breathe through the nose after packing, greatly reducing post-packing discomfort, and greatly improving the packing hemostasis effect and comfort.

[0024] As per the instruction manual Figure 1-4 As shown:

[0025] A posterior nasal packing device with an airway includes: an insertion blind end 100, an airway body 110, and a packing bag 200; the packing bag 200 is fixedly disposed on the insertion blind end 100, covering three-quarters of the surface of the insertion blind end 100; an airway 105 is provided in the area of ​​the insertion blind end 100 not covered by the packing bag 200, and the rear end of the insertion blind end 100 is connected to the airway body 110.

[0026] In this embodiment, the posterior nasal packing device with an air tube enters through the nasal cavity or inferior nasal meatus. The packing sac packs the posterior nasal cavity, and the air tube delivers air to the posterior end of the patient's nasal cavity through the air vent extending into the blind end. This reduces the patient's pain during and after packing. The blind end is adapted to the shape of the nasopharynx and is fixed by the packing sac, making it less prone to movement during swallowing. This allows the patient to breathe through the nose even after packing, greatly reducing post-packing discomfort and significantly improving the hemostatic effect and comfort of packing.

[0027] Specifically, the posterior nasal packing device with an airway tube also includes: a limiting and fixing part 115; one end of the limiting and fixing part 115 is fixedly installed at the rear end of the airway body 110, and the other end is fixedly installed with an airway inlet section 120. The airway inlet section 120 and the airway body 110 are connected and fixed through the limiting and fixing part 115, thereby connecting the inner cavity of the airway body 110 with the outside air; the airway inlet section 120 can also be connected to an oxygen delivery device / nebulizer to deliver oxygen and nebulized therapeutic gas into the airway body 110, and the limiting and fixing part 115 limits the installation of the connecting tube.

[0028] Specifically, at least three air vents 105 are made in the area 103 of the blind end 100 that does not cover the packing body 200. During treatment, the air vents 105 face the oropharynx to ensure unobstructed airflow during and after packing.

[0029] Specifically, the rear end of the tampon body 200 is connected to and fixed to the tampon tube 210. Medical staff can use adhesive tape or rope to fix the tampon tube 210 to the outer surface of the ventilation tube body 110.

[0030] Specifically, a tamping tube receiving channel 116 is provided inside the venting tube body 110, and the tamping tube 210 passes through the tamping tube receiving channel 116. The tamping tube 210 is fixedly installed in the venting tube body 110 through the tamping tube receiving channel 116 to ensure the tamping tube 210 is fixed and to prevent the tamping tube 210 from falling off or moving due to accidental contact.

[0031] Specifically, a filling interface 220 is fixedly installed at the rear end of the filling tube 210; the filling interface 220 is connected to the inflation / deflation device. The inflation / deflation device inflates / deflates the filling bladder 200 through the filling interface and the filling tube, thereby controlling the expansion / contraction of the filling bladder 200.

[0032] Specifically, the filling port 220 is connected to the water filling / pumping device. The water filling / pumping device fills / pumps water into the filling bladder 200 through the filling port and filling pipe, thereby controlling the expansion / contraction of the filling bladder 200.

[0033] Specifically, the outer side of the airway tube 110 is provided with a scale 112. The insertion depth of the posterior nasal packing device with the airway tube is controlled by the scale to ensure accurate and secure packing.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
