Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a self-filling nasal balloon stent. Background Art

[0002] Chronic rhinitis can cause hypertrophy of the nasal conchae, affecting the patient's daily breathing. At night, changes in ambient temperature, changes in sleeping posture, and vagus nerve excitement can aggravate nasal congestion, causing difficulty breathing and affecting the patient's sleep quality.

[0003] Children under the age of 14 are in a period of rapid growth and development. If they suffer from chronic rhinitis for a long time, their breathing will be affected due to blocked nasal cavities, and the body will be in a state of chronic hypoxia for a long time, which will affect the development of all systems in the body to varying degrees, especially the development of the nervous system and brain, which is the most seriously affected, and can cause decreased intelligence, memory loss, lack of concentration, slow reaction, etc.

[0004] Long-term mouth breathing can disrupt facial development, leading to elongated maxilla, protruding teeth, thickened lips, and other symptoms known as "nasal disease face." Large amounts of mucus, if sucked back into the abdominal cavity, can irritate the gastric mucosa and cause digestive symptoms such as loss of appetite and vomiting.

[0005] Chronic rhinitis symptoms fluctuate, and while some don't require surgery, nasal congestion persists. Seasonal allergic rhinitis, while less severe after the season, can still cause nasal congestion during its onset. These patients suffer from nasal congestion, which impacts their daily breathing and, in particular, their sleep quality at night.

[0006] Therefore, there is an urgent need for an auxiliary device for rhinitis to improve the patient's chronic rhinitis condition from a long-term perspective. Utility Model Content

[0007] Currently, rigid, fixed-size nasal stents on the market can easily bruise the patient's nasal mucosa, causing discomfort. Furthermore, the degree and location of nasal obstruction vary from patient to patient, making the placement of fixed-size nasal stents less effective. The present invention provides a self-adjusting, self-filling nasal balloon stent that is simple in structure, easy to use, and low in manufacturing cost. It will not bruise the nasal mucosa during insertion, and the patient can adjust the balloon size according to the degree of patency of their own breathing, and shrink the balloon when removing it to ensure that there is no impact on the nasal mucosa. The present invention's self-filling nasal balloon stent can be reused after removal and disinfection.

[0008] The utility model is achieved through the following technical solutions:

[0009] The utility model provides a self-inflating nasal balloon support, comprising a balloon support mechanism capable of being inserted into and supporting the nasal cavity, and an inflation mechanism capable of inflating air into the balloon support mechanism;

[0010] The balloon support mechanism includes a semi-rigid bottom frame, a semi-rigid ventilation main pillar, a one-way valve and an expandable pressure-resistant balloon. The semi-rigid ventilation main pillar is a hollow structure. The semi-rigid bottom frame is fixed to one end of the semi-rigid ventilation main pillar. The one-way valve is fixed to the semi-rigid bottom frame and communicates with the inner cavity of the semi-rigid ventilation main pillar. The expandable pressure-resistant balloon is fixed to the other end of the semi-rigid ventilation main pillar and communicates with the inner cavity of the semi-rigid ventilation main pillar.

[0011] The inflation mechanism includes an inflation balloon and an inflation needle. The inflation needle is connected to the inflation balloon through a connecting hose, and the inflation needle can be plugged into a one-way valve.

[0012] In order to facilitate processing and forming, the one-way valve is arranged at the center of the semi-rigid bottom frame, and the one-way valve is fixed to the semi-rigid bottom frame through a lateral support structure.

[0013] In order to accurately detect the pressure in the pipeline during the inflation process, a pressure display screen is provided on the connecting hose between the inflation needle and the inflation balloon.

[0014] The beneficial effects of the present invention are as follows: the self-filling nasal balloon stent utilizes physical methods to quickly and effectively solve the patient's nasal congestion problem, improve the patient's daily life, especially the breathing quality when sleeping at night, thereby improving the patient's physical condition, enhancing the body's immunity, and improving the patient's chronic rhinitis condition from a long-term perspective; in addition, the present invention can also be used as an auxiliary device for expanding and filling surgical wounds after nasal surgery.

[0019] like Figure 1-3 A self-inflating nasal balloon stent is shown, comprising a balloon support mechanism capable of being inserted into and supporting the nasal cavity and an inflation mechanism capable of inflating air into the balloon support mechanism;

[0020] Specifically, the balloon support mechanism includes a semi-rigid bottom frame 1, a semi-rigid ventilation main pillar 2, a one-way valve 4 and an expandable pressure-resistant balloon 3. The semi-rigid ventilation main pillar 2 is a hollow structure. The semi-rigid bottom frame 1 is fixed to one end of the semi-rigid ventilation main pillar 2. The one-way valve 4 is arranged in the center of the semi-rigid bottom frame 1. The one-way valve is fixed to the semi-rigid bottom frame 1 through a lateral support structure 8. The lateral support structure 8 is small in size, and the inner side of the semi-rigid bottom frame 1 can still be ventilated. The one-way valve 4 is connected to the inner cavity of the semi-rigid ventilation main pillar 2. The expandable pressure-resistant balloon 3 is fixed to the other end of the semi-rigid ventilation main pillar 2 and is connected to the inner cavity of the semi-rigid ventilation main pillar 2.

[0021] Specifically, the inflation mechanism includes an inflation balloon 5 and an inflation needle 6. The inflation needle 6 is connected to the inflation balloon 5 through a connecting hose. The inflation needle 6 can be plugged into the one-way valve 4. A pressure display screen 7 is provided on the connecting hose between the inflation needle 6 and the inflation balloon 5.

[0022] During use, the inflation needle 6 on the inflation mechanism is inserted into the one-way valve 4 in the center of the semi-rigid bottom frame 1, and then the semi-rigid ventilation main support 2 is slowly inserted into the nasal cavity (control the insertion angle so that the head of the semi-rigid ventilation main support is located between the middle turbinate and the superior turbinate), so that the semi-rigid bottom frame 1 fits the lower edge of the human nostril;

[0023] Then, slowly squeeze the inflatable balloon 5 to slowly expand the expandable pressure-resistant balloon 3 at the head of the semi-rigid ventilation main support 2, thereby widening the nasal passage space and increasing the ventilation volume, thereby relieving the nasal congestion. When the patient feels that breathing is smooth, stop squeezing the inflatable balloon 5 and pull out the inflation needle 6. The patient can then breathe and sleep normally. During the squeezing of the inflatable balloon 5, always pay attention to the pressure value on the pressure display 7 and keep the pressure value within the maximum value range set in the manual to ensure the safety of the balloon.

[0024] After use, insert the exhaust rod into the one-way valve 4 to exhaust the air, shrink the expandable pressure-resistant balloon 3, and take out the semi-rigid ventilation main strut 2; after the semi-rigid ventilation main strut 2 is taken out, it should be cleaned and soaked in disinfectant for next use.

[0025] It should be noted that the parts not involved in the present invention are the same as the existing technology or can be implemented by using the existing technology.
