Problems solved by technology

2. The nasal branch of the great palatine artery is damaged due to the position of the fistula too far behind, or the nasal branch of the upper lip artery is damaged due to the position too far forward, resulting in epistaxis
3. Adhesion between the inferior turbinate and the side wall of the nasal cavity due to improper handling after the operation
Under normal circumstances, limited to the pressure tolerance of the sinuses and their surrounding tissues, the liquid sprayed in the way of uniaxial perforation and dispersive spraying cannot completely cover the lesion, and can only play a simple role in rinsing the sinuses. relatively short stay

Embodiment 1

[0037] Such as figure 2 As shown, a balloon spraying device for treating sinusitis or allergic rhinitis according to a preferred embodiment of the present invention includes an inflatable balloon 1 , a balloon inner tube 4 and a balloon catheter 5 .

[0038] in, figure 2 The filling state of the balloon 1 is shown, and the balloon 1 can be a compliant balloon or a semi-compliant balloon. The balloon inner tube 4 extends axially through the balloon 1, wherein the distal opening 41 of the balloon inner tube 4 leads directly to the lesion, and the proximal opening 42 is connected with a luer joint or a ribbed interface or a trumpet-shaped interface, so as to be compatible with A small vacuum suction device and / or drug storage container (not shown) is connected. The radial diameter of the balloon inner tube 4 is shown as 1 mm in this embodiment. It should be understood that the radial diameter of the balloon inner tube 4 can be adjusted as required, preferably between 0.5-5mm...

Embodiment 2

[0045] Such as image 3 As shown, the balloon spraying device for treating sinusitis or allergic rhinitis according to a preferred embodiment of the present invention includes an inflatable first balloon 10, a second balloon 20, a second balloon catheter 30, Balloon inner tube 40 and first balloon catheter 50 .

[0046] in, image 3 The inflation state of the balloon 10 is shown, which may be a compliant balloon or a semi-compliant balloon. The balloon inner tube 40 extends axially through the first balloon 10 and the second balloon 20, wherein the distal opening 410 of the balloon inner tube 40 leads directly to the lesion, and the proximal opening 420 is connected with a luer joint or a ribbed interface Or trumpet-shaped interface, so as to connect with small vacuum suction equipment. The radial diameter of the balloon inner tube 40 is shown to be about 3 mm in this embodiment. It should be understood that the radial diameter of the balloon inner tube 40 can be adjusted ...

Abstract

The invention provides a sacculus medicine-spraying device for treating nasosinusitis or allergic rhinitis. The sacculus medicine-spraying device comprises an inflatable sacculus, a sacculus inner pipe and a sacculus catheter, wherein the sacculus inner pipe penetrates through the sacculus and extends axially; and the far-end opening of the sacculus catheter is ended in the sacculus. The sacculus medicine-spraying device provided by the invention has the advantages that the prepared effective treating medicine liquid or gelatinous or powdery solid particles can be conveyed to the diseased part of the paranasal sinus, and the cavity part of the frontal sinus and/or the maxillary sinus is used as a medicine storage device, so that the diseased part can be treated by medicines in enough-long treatment period. The sacculus medicine-spraying device also has the advantages that effective medicines are uniformly sprayed to the diseased part by minimally invasive surgery; the medicines stored on the frontal sinus and the maxillary sinus can be conveyed to the diseased part continuously in time along with the swinging of the cilium of the nasal cavity and the flowing of mucus of the nasal cavity; and before the stored medicines are metabolized, the medicines can be directly and continuously fed to the diseased part, and the treating effect of common medicine feeding is greatly improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a balloon medicine spraying device for treating sinusitis or allergic rhinitis. Background technique [0002] Sinusitis and allergic rhinitis are common and frequently-occurring diseases of ENT, which occur between the ages of 5 and 79. According to the survey by the health department: the current global incidence of allergic rhinitis is as high as 10% to 14%, and the incidence of sinusitis accounts for about 15% of the population. Nearly 600 million people in the world are suffering from rhinitis, and it is gradually Upward trend. [0003] 66% of asthma patients are victims of allergic rhinitis. According to experts, if allergic rhinitis is not properly treated, more than one-third of patients will eventually develop asthma. [0004] Nasal sinuses, also known as paranasal sinuses and paranasal sinuses, are multiple air-containing bony cavities around the nasal cavity, which com...
