AI Technical Summary
There is no publicly available medical use of non-invasive ventilators to improve symptoms such as gastroesophageal reflux and bloating. Traditional treatments have problems such as dependence, side effects, and limited effectiveness.
Non-invasive ventilator is used for continuous positive pressure ventilation. By increasing the closing strength of the lower esophageal sphincter, the gastroesophageal reflux channel is blocked. Positive pressure is used to regulate the pressure difference between the thoracic cavity and the stomach, which helps to relieve gas accumulation in the gastrointestinal tract. Combined with humidification function, it reduces irritation to the esophageal mucosa and achieves physical regulation.
It improves symptoms such as gastroesophageal reflux, acid reflux, and bloating in a non-invasive, safe, and side-effect-free manner. It is suitable for long-term use, widely applicable, easy to operate, low in cost, and meets the home care needs of mild to moderate patients.

Abstract
Description
Technical Field
[0001] This invention belongs to the field of new applications of medical devices, specifically relating to a novel medical application of a non-invasive ventilator in improving discomfort symptoms such as gastroesophageal reflux, bloating, acid reflux, and heartburn. Background Technology
[0002] Gastroesophageal reflux disease (GERD), functional bloating, acid reflux, and heartburn are common digestive symptoms with a very high prevalence in the population. Current conventional treatments mainly rely on dietary control, acid-suppressing drugs, prokinetic drugs, and lifestyle adjustments. Drug treatments have drawbacks such as dependence, side effects, and relapse upon discontinuation, while conservative treatments have limited effectiveness and significant individual variability. Currently, there is no clearly disclosed or systematically documented medical application of non-invasive mechanical ventilation in improving bloating and GERD symptoms; related applications represent a novel, undisclosed field. Summary of the Invention
[0003] Purpose of the invention: In view of the shortcomings of the prior art, the present invention aims to provide a new medical application for non-invasive ventilators, opening up a new solution for improving gastroesophageal reflux and bloating discomfort that is non-invasive, safe, and can be used at home for a long time.
[0004] Technical Solution: This invention provides a new application for non-invasive ventilators: Non-invasive ventilators are used in the preparation of auxiliary intervention devices to improve or alleviate symptoms of gastroesophageal reflux, bloating, abdominal distension, acid reflux, and heartburn. The non-invasive ventilator is a clinically routine continuous positive airway pressure ventilation device, an automatically adjustable pressure non-invasive ventilation device, or other home and medical non-invasive respiratory devices.
[0005] The specific mechanisms are as follows: 1. Continuous positive pressure provides physical support to the lower esophageal sphincter in a relaxed state, enhancing its closure strength, blocking the gastroesophageal reflux pathway, and effectively preventing gastric acid and contents from flowing back into the esophagus; 2. Positive pressure ventilation regulates the pressure difference between the thoracic cavity and the stomach, improving the high-pressure reflux state that easily occurs when lying flat at night, thus alleviating nighttime acid reflux and heartburn symptoms from a physiological structural perspective; 3. Regular ventilation airflow helps to clear accumulated gas in the gastrointestinal tract, relieving discomfort such as bloating and frequent belching, and improving the feeling of fullness in the stomach; 4. Combined with the humidification function of the ventilator, the constant-temperature airflow reduces the stimulation of dry airflow on damaged esophageal mucosa, avoiding the induction of esophageal spasms that aggravate reflux discomfort, and helping to maintain the condition of the esophageal mucosa. This mechanism of action differs from the traditional drug-based treatment logic of acid suppression and prokinetic stimulation. It represents a novel intervention approach based on physical and mechanical regulation, is drug-free, safe, has no side effects, and can be used repeatedly for a long time.
[0006] Beneficial Effects: Compared with traditional clinical treatments, this invention has the following advantages: 1. Pure physical therapy, no oral medication required, no drug side effects, no drug resistance, suitable for long-term home use by various mild to moderate patients; 2. Mechanism of action targets the root cause of the disease, improving multiple clinical symptoms such as reflux, acid reflux, and bloating, with highly targeted treatment; 3. Wide applicability, no need for surgical trauma, filling the technological gap in non-invasive physical therapy for mild gastroesophageal reflux disease; 4. Can be used with existing mature home medical devices, simple and convenient to operate, can be used during nighttime rest time, does not affect normal daily life, and has high patient compliance; 5. Only expands the use of medical devices, without the need to develop and produce new medical equipment, low application cost, and easy to promote and popularize in clinical practice. Attached Figure Description Figure 1 is a schematic diagram of wearing a ventilator and selecting a nasal mask or nasal pillow ventilation accessory. Detailed Implementation The technical solution of the present invention will be further described in detail below with reference to preferred embodiments.
[0007] A standard single-level non-invasive ventilator is selected from the market and worn with a nasal pillow. The constant ventilation pressure of the ventilator is adjusted to the range of 6cmH2O-8cmH2, and the humidification temperature is adjusted to 32℃-34℃. When the patient sleeps at night, the upper body should be raised by about 20°. The device should be used continuously for more than 4 hours every night to treat and improve the discomfort symptoms of mild reflux esophagitis, daily bloating, and mild acid reflux at night.
Claims
1. A novel application for a non-invasive ventilator, characterized in that: Non-invasive ventilators are used to improve, relieve or treat symptoms such as bloating, abdominal distension, gastroesophageal reflux, acid reflux, and heartburn.
2. The novel application of the non-invasive ventilator according to claim 1, characterized in that: The non-invasive ventilator is a continuous positive airway pressure (CPAP) non-invasive ventilator or an auto-adjustable pressure (AAP) non-invasive ventilator.
3. The novel application of the non-invasive ventilator according to claim 1, characterized in that: The new application is a non-pharmacological physical and mechanical intervention method that uses positive airway pressure to regulate the pressure balance in the thoracic and abdominal cavities, thereby improving symptoms of bloating and reflux.
4. The novel application of the non-invasive ventilator according to claim 1, characterized in that: The new application is suitable for home-based daily care, nighttime sleep intervention, and auxiliary improvement of mild to moderate gastrointestinal reflux and functional bloating discomfort.
5. A novel application of the non-invasive ventilator according to claim 1, characterized in that, The new application is applicable to patients with reflux esophagitis diagnosed by gastroscopy, as well as patients with functional bloating, recurrent acid reflux, belching and heartburn, but without organic gastrointestinal obstruction.
6. A novel application of the non-invasive ventilator according to claim 1, characterized in that, This use is distinct from the original indications for treating sleep apnea syndrome, chronic obstructive pulmonary disease, and respiratory failure of ventilators.
7. A novel application of the non-invasive ventilator according to claim 1, characterized in that, When using a nasal mask or nasal pillow for ventilation, avoid using a full-mouth nasal mask to prevent swallowing air during ventilation, which can worsen stomach bloating.
8. A novel application of the non-invasive ventilator according to claim 1, characterized in that, The temperature of the humidification system for the ventilator is set to 30℃~37℃ to avoid dry and cold airflow irritating the esophageal mucosa and aggravating reflux symptoms.
