Description

Technical Field

[0001] The present invention relates to an oral-nasal separated breathing training system, belonging to the technical field of medical devices. Background Art

[0002] Breathing is a basic physiological process for maintaining life. It helps to expel waste gas from the body and inhale fresh oxygen through the gas exchange between the body and the external environment. The efficiency of breathing directly affects the oxygen supply to tissues and organs. Therefore, the correct breathing method is crucial for maintaining health. By the contraction of the external intercostal muscles, the ribs rise and the chest cavity expands, thus inhaling air; when the internal intercostal muscles contract, the ribs descend and the chest cavity shrinks, and the air is expelled from the lungs. The rhythmic expansion and contraction process of breathing realizes the gas exchange.

[0003] The breathing methods are mainly divided into two types: thoracic breathing and abdominal breathing. Thoracic breathing mainly relies on the chest muscles to control the intake and output of air and breathes through the expansion and contraction of the chest cavity. Abdominal breathing, on the other hand, promotes the intake and output of gas in the lungs through the movement of the abdominal muscles and the diaphragm. Thoracic breathing is mostly superficial breathing, which is prone to shallow breathing and insufficient ventilation; abdominal breathing is relatively deep, which helps to increase the vital capacity and gas exchange efficiency.

[0004] In the process of medical treatment and rehabilitation, breathing training is very important for improving breathing ability and promoting recovery. Especially during the recovery after surgery or in some special situations, breathing training helps patients better adapt to the new breathing method. However, the compatibility of traditional breathing training devices is poor, unable to effectively distinguish between oral and nasal breathing and thoracic-abdominal breathing, and it is difficult to meet the personalized needs of patients. Especially for patients who need nasal indwelling or have problems such as macroglossia or limited head stiffness and hyperextension, the design of existing devices lacks flexibility and cannot meet the needs of special patient groups, resulting in poor ventilation effect and affecting the safety and effect of training. Summary of the Invention

[0005] The purpose of the present invention is to provide an oral-nasal separated breathing training system to solve the problems of poor compatibility, insufficient ventilation efficiency and inability to meet personalized needs in the existing breathing training devices.

[0010] A respiration detection unit, configured to detect the respiration mode of the trainee, where the respiration mode includes thoracic breathing and abdominal breathing;

[0011] A flow rate adjustment unit, disposed in the main trachea, for adjusting the gas flow rate of the main trachea;

[0012] A controller, which is respectively signal-connected to the respiration detection unit and the switching valve. The controller controls the switching valve to start according to the detection result of the respiration detection unit, so that the nasal tube is connected to the main trachea;

[0013] Or / and; the mouthpiece tube is connected to the main trachea.

[0014] In some embodiments, the respiration detection unit includes a first detection member placed on the chest of the trainee and a second detection member placed on the abdomen of the trainee. The first detection member is used to detect the undulation height of the trainee's chest, and the second detection member is used to detect the undulation height of the trainee's abdomen.

[0015] In some embodiments, an outer edge of the face mask is provided with a first sealing airbag for fitting with the trainee's face.

[0016] In some embodiments, the first sealing airbag is provided with a first ventilation hole and a first rubber pad for closing the first ventilation hole.

[0017] In some embodiments, the nasal tube includes a main tube connected to the switching valve and two branch tubes connected to the main tube. An outer edge of the branch tube is provided with a second sealing airbag for fitting with the trainee's nostrils.

[0018] In some embodiments, the second sealing airbag is provided with a second ventilation hole and a second rubber pad for closing the second ventilation hole.

[0019] In some embodiments, an anti-biting structure is provided inside the mouthpiece tube.

[0039] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the accompanying drawings and combine with embodiments to detail this application.

[0040] Please refer to Figures 1 to 3 , an embodiment of the present application provides a nose and mouth separation breathing training system, which includes a mask 1 for sealing and wearing on the nose and mouth of a trainer, an air pipe line arranged in the mask 1, a breathing detection unit 6 and a controller 7.

[0041] In some embodiments, a first sealing airbag 11 for fitting with the face of the trainer is arranged on the outer edge of the mask 1. To facilitate wearing the mask 1, an elastic headband 9 is also arranged on the mask 1.

[0042] In some embodiments, a first ventilation hole and a first rubber pad for closing the first ventilation hole are arranged on the first sealing airbag 11. Specifically, the first ventilation hole is made according to the principle of reverse air pressure closing. When the inflation device inflates the first sealing airbag 11 through the first ventilation hole, the first rubber pad will be pushed open by the gas pressure. When the inflation stops, the air in the first sealing airbag 11 will apply an outward pressure to the first rubber pad to close the first ventilation hole. It is a conventional structure and will not be elaborated here in detail.

[0043] As described above, the air pipe line includes a main air pipe 4, a nose ventilation pipe 2 and a mouth bite pipe 3. The nose ventilation pipe 2 and the mouth bite pipe 3 are connected to the head end of the main air pipe 4 through a switching valve 5, and the tail end of the main air pipe 4 communicates to the outside of the mask 1. Specifically, the switching valve 5 is a multi-way selection valve, which has two air inlets and one air outlet, and switches the air flow path through rotation or sliding operation to select the connection state between the nose ventilation pipe 2 or the mouth bite pipe 3 and the main air pipe 4.

[0044] In some embodiments, the nose ventilation pipe 2 includes a main pipe 21 connected to the switching valve 5 and two branch pipes 22 communicating with the main pipe 21. Second sealing airbags for fitting with the nostrils of the trainer are arranged on the outer edges of the branch pipes 22.

[0045] In some embodiments, the nasal cannula 2 can also be configured to be detachable, such as a snap-on connection with a conversion valve 5. For patients who can actively cooperate with breathing training, there is no need to insert the nasal cannula 2 into the patient's nostrils to cause discomfort to the patient. For patients who cannot actively cooperate or do not know how to use it, partial training is forced through the nasal cannula 2.

[0046] In some embodiments, the second sealed airbag is provided with a second vent and a second rubber pad for sealing the second vent. In addition, the second sealed airbag can also expand the opening of the trainee's nostrils, thereby improving the circulation efficiency of the airflow.

[0047] It is worth noting that the second vent is also made based on the principle of reverse closure of air pressure. The specific working principle can be found in the aforementioned first vent, which will not be elaborated here.

[0048] In some embodiments, the flow regulating unit is arranged in the main airway 4, and is used to regulate the gas flow of the main airway 4; specifically, the flow regulating unit is detachably connected to the main airway 4, and the flow regulating unit includes a truncated cone-shaped connecting tube 41 and a resistance ball 42 arranged in the truncated cone-shaped connecting tube 41, the end with a smaller diameter of the truncated cone-shaped connecting tube 41 is connected to the conversion valve 5, and baffles with vents are arranged at both ends of the truncated cone-shaped connecting tube 41. The resistance ball 42 is used to block the vents at the end with a smaller diameter of the truncated cone-shaped connecting tube 41 when the patient inhales to reduce the gas flow of the main airway 4, thereby being a trainer. Preferably, one of the baffles is detachably connected to the truncated cone-shaped connecting tube 41, so as to facilitate the replacement of resistance balls 42 with different diameters to adjust the training resistance.

[0049] In some embodiments, an anti-bite structure is provided in the bite tube 3. In detail, the anti-bite structure includes an expansion ring and a bite groove 8 provided on the expansion ring. It is worth noting that the expansion ring is made of a material with a certain hardness, specifically polyurethane, to prevent the bite tube 3 from being over-bite or closed during use, to ensure the smoothness of the pipeline, and to help maintain good airflow and ventilation effects. The bite tube 3 is coated on the expansion ring, and the bite groove 8 is used to limit and guide the teeth of the trainee. Indeed, in other embodiments, the anti-bite structure can also be provided as an adjustable locking mechanism, having two opposing tooth plates and an adjusting member provided between the two tooth plates for adjusting the distance between the two tooth plates, and the adjusting member can be a threaded rod. This application does not make specific limitations on this.

[0050] In some embodiments, an auxiliary ventilation device is further included. The auxiliary ventilation device is connected to the tail end of the main trachea 4. The auxiliary ventilation device is an oxygen bag or a positive pressure ventilator. The oxygen bag is usually an inflated bag that can store and release oxygen to provide additional respiratory support. The positive pressure ventilator helps maintain the airway open and increases oxygen supply by applying positive pressure to the airway during breathing. It is a conventional structure and will not be elaborated here.

[0051] In some embodiments, a humidification tank and an artificial nose are further included between the auxiliary ventilation device and the main trachea 4. The humidification tank and the artificial nose are used to increase the humidity and temperature of the breathing gas, thereby improving comfort. The humidification tank usually contains a water tank and mixes water vapor into the air flow by heating or through air flow. The artificial nose mimics the function of the natural nasal cavity, heats and humidifies the gas to make it closer to body temperature and humidity, thus improving the breathing experience. It is a conventional structure and will not be elaborated here.

[0052] The breathing detection unit 6 is used to detect the breathing mode of the trainer. The breathing mode includes thoracic breathing and abdominal breathing.

[0053] In some embodiments, the breathing detection unit 6 includes a first detection member 61 placed on the chest of the trainer and a second detection member 62 placed on the abdomen of the trainer. The first detection member 61 is used to detect the undulation height of the trainer's chest, and the second detection member 62 is used to detect the undulation height of the trainer's abdomen. Specifically, the first detection member 61 and the second detection member 62 are wearable breathing monitoring patches or displacement sensors.

[0054] The controller 7 is respectively signal-connected to the breathing detection unit 6 and the switching valve 5. The controller 7 controls the switching valve 5 to start according to the detection result of the breathing detection unit 6, so that the nasal tube 2 is connected to the main trachea 4, or / and the mouthpiece tube 3 is connected to the main trachea 4. It should be noted that the controller 7 uses a single-chip microcomputer or a logic circuit to implement signal processing and control functions, which is a conventional technology and will not be elaborated in detail here.

[0055] Due to the application of the above technical solutions, the beneficial effects of this application compared with the prior art are as follows:

[0056] This application can distinguish and adapt to different breathing modes of the trainer, detect the breathing mode of the trainer in real time through the breathing detection unit, and adjust the configuration of the ventilation pipeline to achieve targeted breathing training. By setting the main trachea, nasal tube and mouthpiece tube, and switching through the switching valve, the system can adjust the ventilation path according to the needs of different patients, such as nasal indwelling, enlarged tongue body or head stiffness. This design improves the compatibility of the system and can effectively meet the needs of various special patient groups.

[0057] Meanwhile, the system can automatically adjust the ventilation path according to the real-time detection data, optimize the connection state between the nasal cannula or oral bite tube and the main trachea, thereby improving the ventilation efficiency, adjusting the gas flow through the flow regulation unit to adjust the breathing resistance, enhancing the effect of breathing training, reducing unnecessary breathing pressure, improving the comfort of training, and ensuring the ventilation safety during the training process.

[0058] In addition, the controller of the system can automate the management of the operation of the switching valve, reducing the complexity of user operation.

[0059] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
