Description

Technical Field

[0001] The invention relates to a nasal septum auxiliary treatment device, in particular to a nasal septum fixer provided with an expansion sponge. Background Art

[0002] Septal hematoma refers to the accumulation of blood under the perichondrium or periosteum on one or both sides of the nasal septum. It is generally caused by blood accumulation and edema due to blood stasis. Nasal trauma, nasal surgery and other related blood diseases may cause this symptom, which is very easy to cause abscesses due to infection.

[0003] At present, when the above symptoms occur, the nasal cavity needs to be packed with Vaseline gauze during the treatment process, which can easily cause breathing difficulties for the patient. In addition, the swelling and pain of the nasal cavity will also increase after packing. Summary of the invention

[0004] The present invention aims to solve the problem that during the treatment of nasal septum hematoma in the prior art, patients are prone to breathing difficulties and increased swelling and pain, and provides a nasal septum fixer with an expansion sponge.

[0005] The technical solution adopted by the present invention is: a nasal septum fixer with an expansion sponge, comprising a fixing plate, at least one ventilation tube arranged on the outer side of the fixing plate, and an expansion sponge; the plate surface shape of the fixing plate is adapted to the dividing surface of the nasal septum, and the inner side surface of the fixing plate fits the nasal septum; the expansion sponge is arranged on the fixing plate or on the ventilation tube; the fixing plate and the ventilation tube are both made of flexible materials to enhance the comfort of the user.

[0006] The upper end of the fixing plate is located at the top of the nasal septum, the lower end of the fixing plate is located at the nostril, and a needle guide hole is provided at the lower end of the fixing plate. The guide hole is a through hole or a blind hole. The blind hole is located on the outer side of the fixing plate. During the surgical treatment process, the needle guide hole can be used for suturing the fixing plate and the nasal septum, so that the fixing plate can be fixed in the nasal cavity.

[0007] Furthermore, the ventilation tube is a variable diameter tube, the diameter of the upper end of the ventilation tube is thinner, and the diameter of the lower end of the ventilation tube is thicker, so that it is easy to insert into the nasal cavity.

[0008] Furthermore, one or more ventilation tubes are arranged side by side on the fixed plate, and the direction of the ventilation tubes is the same as the direction of the nasal breathing passage, so that the patient can exhale more smoothly.

[0009] Alternatively, the structure of the ventilation pipe is a Y-shaped ventilation pipe, and a dividing slit with an open end is provided in the middle of the fixed plate, the dividing slit is located between the two branch pipes of the Y-shaped ventilation pipe, and the branch opening of the dividing slit is provided at the upper end of the fixed plate; the expanded sponge is a strip-shaped structure, which is provided on the outer side surface of the fixed plate or on the outer side surface of the fixed plate and the dividing slit; or, the expanded sponge is a sheet-shaped structure, which is fixed on the ventilation pipe.

[0010] Furthermore, the fixing plate and / or the ventilation pipe are provided with fine slits, and the middle part and / or the end part of the expansion sponge are embedded in the fine slits.

[0011] Further, the expanded sponge is a strip-like structure or a sheet-like structure;

[0012] When the expansion sponge strip structure is used, the expansion sponge can be arranged on both sides of the ventilating tube and clamped in the slits on the fixing plate or the slits on the ventilating tube. The direction of the strip expansion sponge is the same as that of the ventilating tube, so that the expansion sponge can evenly fill the nasal cavity.

[0013] The strip expansion sponge can also be arranged in the groove of the fixed plate; the outer side of the fixed plate is provided with a protruding clamping plate, the groove is formed between the protruding clamping plate and the outer wall of the ventilation pipe, and the outer wall of the ventilation pipe close to the protruding clamping plate is vertically arranged on the fixed plate.

[0014] When the sponge sheet structure is expanded, the sheet-like expanded sponge can be wrapped around the ventilation tube and clamped in the slit on the fixed plate or the slit on the ventilation tube. A gap is provided between the sheet-like expanded sponge and the ventilation tube to prevent the expanded sponge from squeezing the ventilation tube and causing difficulty in breathing for the patient.

[0015] The outer side surface of the ventilation pipe is provided with a groove, and the sheet-like expansion sponge can be placed in the groove, so as to limit the movement of the sheet-like expansion sponge on the ventilation pipe.

[0016] Furthermore, a support frame is arranged in the ventilation pipe, and the cross-sectional shape of the support frame is straight-shaped, V-shaped, cross-shaped, etc. The processing method of the support frame is simple, and the supporting stability performance is better.

[0017] Furthermore, a fixing pipe is provided, which is arranged on both sides of the ventilation pipe. The fixing pipe can be used to fix the strip-shaped expansion sponge on the one hand, and can also support the ventilation pipe on the other hand.

[0018] Furthermore, the thickness of the expanded sponge is 1 mm to 4 mm.

[0019] The fixing plate has a length of 53mm-76mm, a width of 19mm-27mm, and a thickness of 1±0.1mm. The appropriate size can be selected according to the size of the patient's nasal cavity, and can also be slightly trimmed by the doctor to make it more suitable for the corresponding patient.

[0020] Compared with the prior art, the present invention has the following beneficial effects.

[0021] 1. The nasal septum fixer with an expandable sponge used in the present invention first puts the fixing plate into the nasal cavity so that the fixing plate can prop up the patient's nasal cavity, and then pours water into the expandable sponge on the fixing plate so that the expandable sponge fills the remaining space of the nasal cavity, thereby providing a stable support for the nasal cavity, allowing the nasal cavity to maintain a regular shape, effectively reducing the user's swelling and pain, and facilitating surgical treatment.

[0022] 2. The nasal septum fixer with an expandable sponge and the ventilation tube used in the present invention can enable the patient to breathe smoothly and support the nasal cavity. A support frame is also provided in the ventilation tube, which supports the inner wall of the ventilation tube and avoids the phenomenon of the support tube being flattened due to external compression of the ventilation tube, so that the patient can always breathe smoothly and feel more comfortable.

[0023] 3. The nasal septum fixer with an expandable sponge used in the present invention has a relatively small volume before being inserted into the nasal cavity, which can reduce the pain when the fixer is installed into the nasal cavity. The expandable sponge entering the nasal cavity becomes larger in volume after being pumped with water, and can also play a supporting role for the nasal cavity. At the same time, the expandable sponge is easy to install, which reduces the processing cost of the nasal septum fixer. BRIEF DESCRIPTION OF THE DRAWINGS
