Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically providing a breathable, non-slip nasal balloon stent. Background Technology

[0002] Currently, nasal stents used in rhinoplasty or reconstructive surgery fall into two categories: one is a mesh metal stent, which provides good support but cannot perfectly conform to the shape of the nasal cavity, and its removal can easily cause secondary damage to the nasal mucosa; the other is an inflatable balloon stent, which can conform to the shape of the nasal cavity, is easy to adjust, and does not cause secondary damage during removal, but it can obstruct the airway after insertion, forcing patients to breathe through their mouths, causing discomfort. CN221905317U discloses a ventilable nasal balloon stent, but its airway is located at the innermost part of the nasal cavity, while the nasal airway is located on the upper part of the palate. When the balloon stent is inserted, the airway will press against the innermost part of the nasal cavity, causing patient discomfort and poor ventilation.

[0003] In addition, most existing nasal stents are balloon-shaped, made of silicone. When wearing the balloon after surgery, it is easy for it to slip out of the nasal cavity because the surface of the balloon is covered with blood and other mucus. After surgery, additional fixation methods are required, which puts an extra burden on the patient. At the same time, the balloon inflation volume can only be determined based on the doctor's experience, and it is impossible to accurately assess the fixation effect of the balloon.

[0004] In view of the above problems, there is an urgent need in the field for a nasal stent that facilitates patient breathing, provides effective support, and allows for monitoring of balloon pressure. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model provides a breathable, non-slip nasal balloon support, including a nasal balloon, an inflation tube, a pressure-indicating balloon, and a pressure indicator. The nasal balloon has a breathing channel and an inflation port inside. The lower end of the inflation tube is connected to the inflation port, and the upper end is connected to the pressure-indicating balloon. A pressure indicator is located on the upper part of the pressure-indicating balloon, and a one-way valve is located on the upper part of the pressure indicator. The shape of the nasal balloon conforms to the nasal cavity, and its breathing channel is directly aligned with the airway inside the nasal cavity. Even after the nasal balloon is inflated, the breathing channel remains open, and the front end of the balloon does not cause discomfort inside the nasal cavity. The nasal balloon is covered with a mesh elastic medical bandage, which can stop bleeding inside the nasal cavity. Additionally, the bandage increases friction after absorbing blood, preventing the nasal balloon from dislodging from the nasal cavity. The pressure-indicating balloon and pressure indicator are integrated into a single unit. The balloon's inflation status can be observed to help identify the nasal balloon pressure, while the pressure indicator displays the inflation pressure in real time, allowing doctors to make timely adjustments during balloon inflation. Additionally, the nasal balloon support comes with a matching ear hook and lanyard for easy placement on the patient's ear.

[0006] The specific technical solution provided by this utility model is as follows:

[0007] A breathable, non-slip nasal balloon stent includes a nasal balloon, an inflation tube, a pressure-indicating balloon, and a pressure indicator. The nasal balloon has a breathing channel and an inflation port inside. The lower end of the inflation tube is connected to the inflation port, and the upper end is connected to the pressure-indicating balloon. The pressure-indicating balloon has a pressure indicator on its upper part, and a one-way valve on its upper part. An ear loop lanyard is provided between the pressure-indicating balloon and the pressure indicator and is connected to the ear loop.

[0008] The nasal balloon stent with the above-described structure features a balloon that conforms perfectly to the nasal cavity, providing better comfort. The balloon has an internal breathing channel and inflation port. The breathing channel is directly aligned with the airway within the nasal cavity, ensuring that inflation does not obstruct airflow. The balloon is covered with a mesh elastic medical bandage for hemostasis within the nasal cavity. The bandage also increases friction after absorbing blood, preventing the balloon from dislodging. The pressure indicator balloon and pressure indicator, connected to the upper end of the inflation tube, are integrated into a single unit. The balloon's inflation status can be observed to help identify the balloon pressure, while the pressure indicator displays the inflation pressure in real time, allowing doctors to make timely adjustments during balloon inflation.

[0009] The specific structure of the nasal balloon stent is as follows:

[0010] The nasal balloon is shaped to fit the nasal cavity and has an internal airway and inflation port. The airway is directly aligned with the airway inside the nasal cavity. When the nasal balloon is inflated, it will not affect the ventilation of the airway, and the front end of the nasal balloon will not cause discomfort inside the nasal cavity.

[0011] Furthermore, the thickness of the airway support wall of the nasal balloon is greater than that of the upper and lower walls of the balloon, ensuring that the airway will not be compressed and sealed during balloon inflation, thus not affecting ventilation; the upper arm wall of the balloon is the thinnest part of the balloon, ensuring that the balloon expands upwards after inflation; the lower wall of the balloon is thicker than that of the upper and side walls, ensuring that the lower part of the balloon remains unchanged after inflation; the side walls of the balloon gradually thicken from top to bottom, ensuring that the balloon expands mainly upwards after inflation, with some limitation on lateral expansion.

[0012] Furthermore, the pressure-indicating balloon and the nasal balloon have the same volume.

[0013] Furthermore, the nasal balloon is wrapped with a mesh elastic medical bandage, which helps to stop bleeding inside the nasal cavity. After absorbing blood, the bandage increases friction, preventing the nasal balloon from detaching from the nasal cavity. After the mesh elastic medical bandage has been wrapped around the nasal balloon for a week, it is adhered to the thicker part of the lower wall of the balloon. When the nasal balloon is inflated, the lower part does not expand significantly, ensuring the adhesion remains intact. When the upper part expands, the bandage, being a mesh structure with a certain degree of elasticity, expands with the nasal balloon, ensuring its support.

[0014] The lower end of the inflation tube is inserted into the inflation port of the nasal balloon, and the connection is secure to ensure a tight seal. The upper end is connected to a pressure indicator balloon, which has a pressure indicator and a one-way valve. After gas is injected into the inflation tube through the one-way valve, it enters the nasal balloon through the inflation port, inflating the balloon and achieving the desired expansion effect. Once expansion is achieved, the one-way valve can be closed.

[0015] Furthermore, an ear loop lanyard is provided between the pressure indicating balloon and the pressure indicator, and is connected to the ear loop. One end of the ear loop connected to the ear loop lanyard has an internal through hole, and the middle of the through hole is connected to a threaded hole. A fixing seat is provided in the threaded hole for fixing the ear loop lanyard.

[0016] Furthermore, the head of the fixation device can be made into various cartoon shapes, which can reduce the resistance of young patients to wearing nasal balloon stents. At the same time, the end of the ear loop lanyard connected to the ear loop has several protrusions with certain intervals, which can be adjusted in length to accommodate patients who need different lanyard lengths.

[0017] Before use, ensure that the mesh elastic medical bandage has covered the nasal balloon for one circumference and is adhered to the lower wall of the balloon. Also ensure that the lower end of the inflation tube is inserted into the inflation port of the nasal balloon and securely fastened. Then, place the lower wall of the nasal balloon against the middle of the bridge of the nose, aligning the breathing channel with the nasal airway. Pass the ear loop lanyard through the internal hole of the ear loop and adjust it to the appropriate position. Tighten the fixing seat and adjust the ear loop to secure it to the patient's ear. After placement, inflate the nasal balloon with a medium (gas or saline) through the one-way valve and inflation tube. Observe the balloon's expansion status and the pressure indicator's dial display. Adjust the inflation pressure to achieve the appropriate balloon expansion, thus completing the nasal balloon support setup.

[0018] Compared with the prior art, the present invention has achieved the following technical effects:

[0019] (1) The nasal balloon is designed to fit the shape of the nasal cavity. It has a breathing channel and an inflation port inside. The breathing channel is directly facing the airway in the nasal cavity, resulting in good ventilation. After the nasal balloon is inflated, it will not affect the ventilation of the breathing channel, and the front end of the balloon will not cause discomfort to the inside of the nasal cavity.

[0020] (2) The nasal balloon is covered with a mesh elastic medical bandage. In addition to stopping bleeding in the nasal cavity, the bandage can increase friction after absorbing blood, thus preventing the nasal balloon from falling out of the nasal cavity and playing a non-slip role.

[0021] (3) The pressure indicator balloon and the pressure indicator are integrally molded. The inflation state of the pressure indicator balloon can be observed to help identify the pressure of the nasal balloon. The pressure indicator can display the inflation pressure in real time, which makes it easier for doctors to make timely adjustments during the inflation of the nasal balloon, thus improving accuracy, comfort and stability.

[0022] (4) A threaded hole and a fixing seat are provided in the middle of the through hole inside the ear hook to fix the ear hook lanyard. The head of the fixing seat can be made into various cartoon shapes, which can reduce the resistance of young patients to wearing the nasal balloon stent. At the same time, the end of the ear hook lanyard connected to the ear hook has several protrusions with a certain interval, which can be adjusted for patients who need different lanyard lengths.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] This invention provides a breathable, non-slip nasal balloon stent, such as... Figure 1 As shown, it includes a nasal balloon 1, an inflation tube 2, a pressure-indicating balloon 3, and a pressure indicator 4; wherein, as shown... Figure 2 The nasal balloon 1 shown has a breathing channel 1-5 and a balloon inflation port 1-6 inside; the lower end of the inflation tube 2 is connected to the balloon inflation port 1-6, and the upper end is connected to the pressure indicating balloon 3. The pressure indicating balloon 3 has a pressure indicator 4 on its upper part, and a one-way valve 5 on its upper part. An ear hook lanyard 6 is provided between the pressure indicating balloon 3 and the pressure indicator 4, and the ear hook lanyard 6 is connected to the ear hook 7.

[0032] The specific implementation method is as follows:

[0033] First ensure that before use, Figure 5 The mesh elastic medical bandage 8 shown has wrapped around the nasal balloon 1, avoiding the airway 1-5, and is firmly bonded to the lower wall 1-4 of the balloon, ensuring that the lower end of the inflation tube 2 is inserted into the inflation port 1-6 of the nasal balloon and firmly bonded; the lower wall 1-4 of the nasal balloon 1 is placed against the middle of the bridge of the nose, so that the airway 1-5 is directly opposite the airway inside the nasal cavity (e.g., Figure 6 As shown, the ear loop sling 6 is passed through the internal through hole of the ear loop 7. The ear loop sling 6 is adjusted to a suitable position, the fixing seat 7-1 is tightened, and the ear loop 7 is adjusted to fix it to the patient's ear. After placement, gas or saline is injected into the nasal balloon 1 through the inflation tube 2 via the one-way valve 5. By observing the expansion state of the pressure indicator balloon 3 and the results displayed on the dial of the pressure indicator instrument 4, the inflation pressure is adjusted to make the expansion state of the nasal balloon 1 suitable, thus completing the placement of the nasal balloon support.

[0034] Figure 2 The diagram shows the structure of the nasal balloon 1, which is shaped to fit the nasal cavity for better comfort. It has a separate breathing channel 1-5 and a balloon inflation port 1-6 inside. One end of the breathing channel 1-5 is directly facing the airway inside the nasal cavity. After the nasal balloon 1 is inflated, it will not affect the ventilation of the breathing channel 1-5, and the front end of the nasal balloon 1 will not cause discomfort to the inside of the nasal cavity.

[0035] like Figure 3 and 4As shown, the thickness of the airway support wall 1-1 of the nasal balloon 1 is greater than that of the upper wall 1-2 and the lower wall 1-4 of the balloon, ensuring that the airway 1-5 will not be compressed and sealed during the inflation of the nasal balloon 1, thus not affecting ventilation; the upper wall 1-2 of the balloon is the thinnest part of the whole, ensuring that the balloon expands upward as a whole after inflation; the lower wall 1-4 of the balloon is thicker than that of the upper wall 1-2 and the side wall 1-3 of the balloon, ensuring that the lower part of the nasal balloon 1 remains unchanged after inflation; the thickness of the side wall 1-3 of the balloon gradually increases from top to bottom, ensuring that the nasal balloon 1 expands mainly upward after inflation, and the expansion to the sides is somewhat limited.

[0036] like Figure 5 As shown, the nasal balloon 1 is externally wrapped with a mesh elastic medical bandage 8, which can stop bleeding inside the nasal cavity. After the mesh elastic medical bandage 8 absorbs moisture, it can increase friction and prevent the nasal balloon 1 from falling out of the nasal cavity. After the mesh elastic medical bandage 8 has been wrapped around the nasal balloon 1 for a week, it is adhered at the thicker part of the lower wall 1-4 of the balloon. When the nasal balloon 1 is inflated, the lower part does not expand much, which can ensure the adhesion effect and prevent it from falling off. When the upper part expands, because the bandage itself has a mesh structure and a certain degree of elasticity, it can expand with the nasal balloon 1, ensuring the support effect of the nasal balloon 1.

[0037] The lower end of the inflation tube 2 is inserted into the inflation port 1-6 of the balloon and is firmly bonded to ensure a seal. The pressure indicator balloon 3 and the pressure indicator 4 connected to the upper end of the inflation tube 2 are integrally formed. The inflation state of the pressure indicator balloon 3 can be observed to help identify the pressure of the nasal balloon 1. The pressure indicator 4 can display the inflation pressure in real time, which is convenient for doctors to make timely adjustments during the inflation of the nasal balloon 1.

[0038] The pressure indicator 4 is equipped with a one-way valve 5. After gas is injected into the inflation tube 2 through the one-way valve 5, it enters the nasal balloon 1 through the balloon inflation port 1-6, inflating the balloon and achieving the expansion effect. Then the one-way valve 5 can be closed.

[0039] An ear loop sling 6 is provided between the pressure indicating balloon 3 and the pressure indicator 4, and is connected to the ear loop 7. The end of the ear loop 7 connected to the ear loop sling 6 has an internal through hole, and the middle of the through hole is connected to a threaded hole. A fixing seat 7-1 is provided in the threaded hole for fixing the ear loop sling 6. The end of the ear loop sling 6 connected to the ear loop 7 has several protrusions with a certain interval, which can be adjusted in length to accommodate patients who require different sling lengths.

[0040] Preferably, the pressure-indicating balloon 3 and the nasal balloon 1 have the same volume.

[0041] The head of the fixation seat 7-1 can be made into various cartoon shapes, which can reduce the resistance of young patients to wearing a nasal balloon stent.

[0042] In summary, the breathable, non-slip nasal balloon support provided by this utility model features a nasal balloon shaped to fit the nasal cavity. Its internal breathing channel is directly aligned with the nasal airway, ensuring good ventilation. Inflation of the nasal balloon does not obstruct airflow, and the balloon's tip does not cause discomfort inside the nasal cavity. The nasal balloon is covered with a mesh elastic medical bandage, which, in addition to stopping bleeding within the nasal cavity, increases friction after absorbing blood, preventing the balloon from slipping out and providing a non-slip effect. A pressure-indicating balloon and pressure indicator are installed on the inflation tube, allowing doctors to make timely adjustments during balloon inflation, improving accuracy, comfort, and stability. It also includes matching ear hooks and lanyards for easy placement on the patient's ear.

[0043] While the specific embodiments of this utility model have been described in detail above, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model. Modifications or variations that do not involve creative labor are still within the protection scope of this utility model.
