[0016] As Figure 1The two sides of the mask body 10 are provided with binding rings 12, the binding rings 12 are used for allowing elastic bands (not shown in the figure) to pass through, so that the elastic bands are fixed with the mask body 10, wherein the mask body 10 is generally connected with two elastic bands, one elastic band is worn around the neck of the human body, and the other elastic band is worn above the occipital protuberance of the head, which is the same as the wearing mode of the N95 mask, so that the stable fixation of the mask body 10 on the head of the patient is realized in a four-point fixation mode.

[0017] In the utility model, the mask body 10 is generally oval, and this shape is more fitted to the human face and has better fixation.

[0018] As Figure 4 The breathing training mouth 20 comprises a breathing round pipe 21, one end of the breathing round pipe 21 is fixed to the opening 101, and the other end extends into the internal space 102 of the mask body 10, the end of the breathing round pipe 21 extending into the internal space 102 is provided with a detachable blowing mouth 23, the blowing mouth 23 is used for being contained in the mouth, a one-way breathing valve 22 allowing only outward exhalation is arranged in the breathing round pipe 21, and the internal wall of the breathing round pipe 21 is provided with a gas flow detection probe 51 and a carbon dioxide detection probe 61, and the gas flow detection probe 51 and the carbon dioxide detection probe 61 are between the one-way breathing valve 22 and the blowing mouth 23.

[0019] In the utility model, in order to eliminate the problem that air tightness is difficult to control, the blowing mouth 23 is designed to be contained in the mouth. The one-way breathing valve 22 is used for allowing the wearer to only exhale outward through the blowing mouth 23, so as to avoid inhaling gas through the blowing mouth 23, so that the wearer can be passively trained to breathe correctly.

[0020] In actual design, different models of blowing mouths 23 are provided for the breathing round pipe 21, the blowing mouths 23 of different models allow different degrees of smoothness of gas flow, so that the gas flow is adjusted to adjust the breathing resistance by replacing the blowing mouth 23, that is, the exhalation rate is adjusted, so as to improve the rehabilitation training efficiency. The patient can install the blowing mouth 23 of a suitable model according to individual needs. Here, the blowing mouth 23 is a well-known component in the art and is not limited, for example, a gas valve for adjusting the gas flow to adjust the breathing resistance can be arranged on the blowing mouth 23.

[0021] Based on the above design that the patient contains the blowing mouth 23 in the mask body 10 and places the nose on the arc-shaped notch 11 outside the mask body 10, the patient can well perform the breathing training by inhaling through the nose and exhaling through the mouth, which avoids causing the patient to breathe not smoothly, improves the use comfort, and greatly reduces the problem of insufficient air tightness by containing the mouth.

[0026] In the utility model, the airflow sensor is used to measure the gas flow rate of the patient's exhalation, so as to calculate the relevant respiratory data (for example, FEV1 / FVC index) to reflect the patient's respiratory condition, so as to evaluate the patient's respiratory mode, so as to guide the patient to use the correct respiratory mode for effective training.

[0027] In the utility model, the carbon dioxide sensor is used to monitor the carbon dioxide amount of the patient's exhalation in real time during the training process, and the carbon dioxide concentration is an important index reflecting ventilation function, and the patient can be found in time when the patient has pulmonary encephalopathy caused by carbon dioxide retention. This kind of carbon dioxide monitoring method is particularly suitable for chronic obstructive pulmonary disease patients. Chronic obstructive pulmonary disease (COPD) is a chronic bronchitis and emphysema with airflow obstruction, which can further develop into pulmonary heart disease and respiratory failure. For COPD patients, due to expiratory dyspnea, the carbon dioxide stored in the patient's alveoli is difficult to discharge, and there is a risk of carbon dioxide retention and pulmonary encephalopathy. Therefore, the safety of COPD patients in the process of using the utility model is greatly improved.

[0028] Here, the control chip, for example, adopts a microprocessor, which is a well-known device in the field.

[0031] In actual application, the blowing nozzle 23 of the breathing training mouth 20 needs to be inserted into the mouth cavity teeth, and the end of the blowing nozzle 23 is usually flush with or slightly protrudes from the silica gel soft pad 13. For the convenience of understanding, Figure 1 Only the position of the breathing training mouth 20 is shown.

[0033] In actual design, the mask body 10, the blowing nozzle 23 and the silica gel soft pad 13 are all made of existing medical antibacterial materials. For example, the mask body 10 is made of PVC (polyvinyl chloride) material, and in addition, the mask body 10 can be provided with supporting ribs according to needs, so that the mask body 10 can better bulge to form the inner space 102 for accommodating the breathing training mouth 20.

The patient holds the mouthpiece 23 to ensure air tightness, and then the patient can start breathing training by using the breathing mode of nasal inhalation and oral exhalation. When the patient exhales, the airflow detection probe 51 detects the flow rate of the exhaled gas and transmits the detection signal to the airflow detection circuit 52, so that the airflow detection circuit 52 feeds back the detection result to the control chip, thereby calculating the related breathing data, reflecting the breathing condition of the patient at this time and displaying on the display instrument to evaluate the breathing mode of the patient and guide the patient to use the correct breathing mode for training, and evaluate the rehabilitation condition of the patient. At the same time, the carbon dioxide detection probe 61 detects the amount of carbon dioxide in the exhaled gas and transmits the detection signal to the carbon dioxide detection circuit 62, so that the carbon dioxide detection circuit 62 feeds back the detection result to the control chip, so as to display and alarm on the display instrument when the amount of carbon dioxide is lower than the threshold value (indicating that the patient may have carbon dioxide retention), avoiding the occurrence of pulmonary encephalopathy in the patient.
