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, the spraying device for treating sinusitis or allergic rhinitis according to a preferred embodiment of the present invention includes an outer tube 1 and an inner tube 2 , wherein the outer tube 1 and the inner tube 2 extend coaxially and axially. The distal opening 3 of the inner tube 2 is in figure 2 is shown as housed in the outer tube 1, while in image 3 is shown axially protruding from the outer tube 1 .

[0038] From image 3 It can be seen from FIG. 1 that the tube body near the distal opening 3 of the inner tube 2 is split in the circumferential direction (with a slit 31 ), thereby forming a radially expandable split opening, shown as a V-shaped split opening.

[0039] The distal opening 3 of the inner tube 2 leads directly to the lesion, while the proximal opening 4 is connected with a luer joint or a ribbed joint or a trumpet-shaped joint, so as to be connected with a small vacuum suction device and a drug storage container (no...

Embodiment 2

[0057] The spraying device for treating sinusitis or allergic rhinitis according to this embodiment is similar to Embodiment 1, including an outer tube (not shown) and an inner tube 20, wherein the outer tube and the inner tube 20 are coaxial extend. Different from Embodiment 1, the tube body near the distal opening 30 of the inner tube 20 does not have cracks, but is circumferentially continuous, such as Figure 4 shown.

[0058] Near the distal opening 30 , two spring bodies 21 respectively extend radially outward from the outer surface of the inner tube 20 . One end 21a of the spring body 21 can be fixedly connected to the outer surface of the inner tube 20 by any suitable means. The other end 21b of the spring body 21 respectively abuts against the two support plates 22 , of course, the other end 21b of the spring body 21 can also be fixedly connected to the support plate 22 by any suitable means. The axially extending support plates 22 are each arranged perpendicular t...

Embodiment 3

[0062] The spraying device for treating sinusitis or allergic rhinitis according to this embodiment is similar to Embodiment 2, including an outer tube and an inner tube extending coaxially and axially, and the distal opening and the proximal opening of the inner tube are circumferentially continuous opening. The difference from Embodiment 2 is that there is no support plate near the opening of the distal end of the inner tube, and the spring body 210 and the recovery line 230 are also different from Embodiment 2, such as Figure 5 shown. The two ends 210a and 210b of the spring body 210 protruding axially from the inner tube are respectively fixed near the distal opening of the inner tube, and the recovery wire 230 runs through the spring body 210 and extends toward the proximal opening.

[0063] In the first state, the distal opening is accommodated in the outer tube, and at this time the spring body 210 is also accommodated in the outer tube and presents a compressed state...

Abstract

The invention provides a medicine spraying device for treating nasosinusitis or allergic rhinitis. The medicine spraying device comprises an outer pipe and an inner pipe which extend coaxially along the axial direction; a radially-expanded element for opening a diseased part is arranged near the far-end opening of the inner pipe; the element is contained in the outer pipe when in a first state; and the element extends from the outer pipe when in a second state and directly acts on the diseased part to enable the diseased part to maintain a radially-expanded state. The 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.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a 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 communicate...
