[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-4 As shown, an artificial airway breathing trainer includes a mouth tube 1, which plays a connecting role. The front end of the mouth tube 1 is connected to the artificial airway to facilitate the patient's breathing training.

[0024] An inhalation tube 2 and an exhalation tube 9 are respectively arranged at the rear end of the oral tube 1. The inhalation tube 2 is used to guide air into the patient's lungs, increase the patient's inhalation resistance, and help to perform effective breathing exercises. A fixed ring 5 is arranged in the inhalation tube 2, and the fixed ring 5 plays a supporting role. A spring 6 is arranged on the outside of the fixed ring 5, and the spring 6 is used to provide resistance. A blocking piece 7 is arranged on the outside of the spring 6, and a blocking ring 8 is arranged outside the blocking piece 7. The blocking piece 7 is pushed against the blocking ring 8 by the spring 6, so that the inhalation tube 2 can only produce a one-way ventilation effect. When the patient inhales, the external airflow enters to push the spring 6 open for gas to enter for easy inhalation. The elastic force of the spring 6 here should not be too large, and appropriate elasticity is selected to facilitate the patient to inhale.

[0025] The expiratory tube 9 is used to guide the patient's exhaled airflow, increase the exhalation resistance, and promote exhalation training. A fixed column 10 is arranged in the expiratory tube 9. The fixed column 10 plays a fixed connection role. The fixed column 10 is vertically connected to the inner wall of the expiratory tube 9. The fixed column 10 is connected to a connecting column 11. The connecting column 11 is perpendicular to the fixed column 10 and parallel to the expiratory tube 9. A fan 12 is arranged on the connecting column 11. The fan 12 can rotate with the airflow, and is used to adjust the expiratory airflow and increase the exhalation resistance. At the same time, the expiratory tube 9 can also ventilate inwardly to facilitate the patient's inhalation.

[0026] The following is a detailed description of the design of the above key components:

[0027] The rear end of the mouth tube 1 is connected to the inhalation tube 2 and the exhalation tube 9 through a three-way connection. This design can ensure that the mouth tube 1 is connected to the inhalation tube 2 and the exhalation tube 9 at the same time, making the inhalation and exhalation process smoother.

[0028] The fixed ring 5 and the sealing ring 8 are embedded in the inner wall of the air intake pipe 2, and a number of springs 6 are distributed in a circle around the center of the fixed ring 5. The embedded design of the fixed ring 5 and the sealing ring 8 can ensure the fixed position inside the air intake pipe 2. The springs 6 around the fixed ring 5 can provide uniform and appropriate elasticity and resistance to enhance the training effect.

[0029] The area of ​​the blocking piece 7 is larger than the area of ​​the central hole of the blocking ring 8, which can ensure that the blocking piece 7 can effectively block the inhalation tube 2, so that the patient cannot exhale gas from the inhalation tube 2, and the inhalation tube 2 is kept unidirectional.

[0030] The number of the fixing columns 10 is two and they are arranged at both ends of the connecting column 11 . Both ends of the fixing columns 10 are fixed to the inner wall of the exhalation tube 9 . The fixing columns 10 are used to fix the connecting column 11 , and the fan blades 12 are fixed through the connecting column 11 .

[0031] Embodiment 2 is an artificial airway breathing trainer as shown in embodiment 1, wherein the inhalation tube 2 is externally connected to a high-flow oxygen inhalation device, and oxygen is supplied externally to facilitate oxygen inhalation for hypoxic patients.

[0032] The inhalation tube 2 is provided with a connecting tube 3, which is used to connect a nasal catheter. The nasal catheter is connected to an external oxygen supply device to facilitate the patient to inhale oxygen and directly introduce oxygen. A cap 4 is provided on the outside of the connecting tube 3. The design of the cap 4 can protect the connecting tube 3 and prevent dust or foreign matter from entering.

[0033] Embodiment 3, as shown in Embodiment 1, an artificial airway breathing trainer, the blade 12 is a blade 12 of an electric fan, and the relevant structure can refer to the description in the application number 201721603845.5 A new type of wind turbine blade, the blade 12 leads to a wire 13, the wire 13 passes through the connecting column 11 and the fixed column 10 and extends out of the expiratory tube 9, and the outer side of the wire 13 is connected to the alarm 14. According to Faraday's law of electromagnetic induction, the blade 12 will cut the magnetic field line when rotating to generate an induced current. The induced current generated by the rotation of the blade 12 during inhalation and exhalation can be used to monitor the patient's breathing, such as monitoring the user's breathing frequency, depth and regularity. This monitoring process can be achieved by connecting the wire 13 and the alarm 14. When an abnormal situation is sensed, such as irregular or interrupted breathing, the alarm 14 can send an alarm signal to remind the user or guardian to intervene in time to ensure the safety of the patient.

[0034] The alarm 14 is a prior art, and triggers corresponding alarm actions according to preset thresholds or conditions, such as sound alarms or flash alarms. In this case, the induced current generated by the rotation of the blades 12 can be used as a signal to trigger the alarm 14. Once an abnormal situation, such as irregular breathing or cessation of breathing, is sensed, the alarm 14 will immediately send out a corresponding alarm signal. For the relevant principles and structures of the alarm with application number 200880129022.0, the relevant circuits can refer to the relevant contents recorded in the alarm driving circuit with application number 201380033308.X.

[0035] The specific design of the alarm 14 can set different parameters and functions as needed, such as setting different alarm levels, adjusting sensitivity, setting delay time, etc. By combining with the induced current generated by the fan blades 12, the alarm 14 can effectively monitor the user's breathing and provide timely alarm information to ensure the safety of the user.

[0036] The standard parts used in the utility model can all be purchased from the market, special-shaped parts can be customized according to the description in the specification and the drawings, the specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art, the machinery, parts and equipment all adopt the conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here. The content not described in detail in this specification belongs to the prior art known to professional and technical personnel in this field.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
