Detailed Description
In order to clearly understand the technical contents of the present invention, the following embodiments are specifically illustrated in detail.
As shown in fig. 1, the present invention is an aerosol visualization system, wherein the aerosol visualization system comprises: a patient model 4 having a nasal cavity 5 and an oral cavity 6; the aerosol generator 12 is used for generating aerosol simulating the breathing of a patient, and the aerosol generator 12 is connected with the oral cavity and the nasal cavity of the patient model; a background plate 3 provided at a right anterior sagittal position of the oral cavity and nasal cavity of the patient model 4; the laser emitter 2 is arranged below the background plate 3, and the laser emitter 2 is arranged to emit laser to completely cover the aerosol range; the camera 1 is vertically arranged at a preset distance of the background plate 3, so that the background plate 3 is positioned between the patient model 4 and the camera 1, and the propagation range and the dead time of the aerosol are recorded through the camera 1.
The laser generator is preferably capable of generating a laser generator with a wavelength of 532nm, which results in a better scattering pattern.
In the aerosol visualization system provided by the present invention, the patient model preferably has a complete upper respiratory tract, i.e., the oral cavity and the nasal cavity.
The utility model provides a system can utilize the aerosol of the smog simulation patient exhalation that aerosol generator produced to it is visual to shine messenger aerosol with laser, with camera imaging record, and the result is visual, so that study aerosol's propagation range and dead time. Therefore, the device for effectively preventing and controlling the aerosol is reasonably selected in the high-incidence stage of the respiratory infectious diseases, and the design of new equipment and the improvement of the existing equipment are guided.
Generally, the aerosol has a diameter of 0.001-100 micrometers, and the aerosol generator is preferably an emitter capable of generating aerosol below 1 micrometer, so that the aerosol generated by a patient is the same as the aerosol generated by the aerosol generator in diameter range, that is, the motion trajectory, the dead time and the like in the air are the same, and therefore, the aerosol generated by the aerosol generator can effectively simulate the aerosol carrying germs generated by the patient. In order to assist in controlling the flow rate of the aerosol, the aerosol generator 12 is communicated with the airway 7 of the patient model through a pipeline 9, and the pipeline 9 is provided with a flow rate control valve 10 and a flow rate detector 8 so as to simulate the airflow when the patient breathes. The aerosol generated by the aerosol generator is delivered to the airway 7 of the patient model by the pipeline 9 after adjusting the flow rate, and is exhaled through the oral cavity 6 and the nasal cavity 5.
The flow rate of the aerosol can be adjusted according to different simulated conditions, such as normal breathing of the patient, high flow oxygen inhalation by the patient, noninvasive mask by the patient, etc., so as to simulate the propagation range of the aerosol generated by the patient under different conditions.
To further simulate a patient with new coronavirus pneumonia, the patient model preferably uses a lung injury simulator 11. The existing lung injury simulator, also called simulated lung, can be used to simulate the condition of lung injury of different degrees by changing the volume of the lung, so as to more accurately simulate the propagation of airflow through the respiratory tract.
Therefore, different breathing conditions of the patient can be simulated by adjusting different flow rates of the aerosol, the lung injury condition of the patient can be simulated by simulating the lung, and the situation of different patients can be simulated more accurately by combining the two conditions.
The patient model may be configured with respiratory support devices such as high flow oxygen inhalation, noninvasive positive airway pressure masks, and the like.
When the system provided by the utility model is used, after the aerosol passes through the air passage 7, the aerosol is exhaled through the oral cavity and the nasal cavity, the laser emitter irradiates the exhaled aerosol for imaging, and the camera records the aerosol imaging taking the background plate as the bottom for subsequent analysis; in this process, the patient model may wear the respiratory support system to assess the aerosol generated by the patient using the respiratory support system.
Adopted the utility model discloses an aerosol visual system, it is visual with the aerosol of patient's exhalation, the scope and the dead time of broadcasting of the aerosol that produce when effective analysis patient uses respiratory support system (high flow oxygen uptake, trachea cannula etc.) provide the basis for the clinical protection of respiratory tract infection disease.
Therefore, the utility model has the advantages that:
1) in the stage of high incidence of respiratory infectious diseases, medical care is guided to reasonably select equipment for effectively preventing and controlling aerosol; if no better equipment exists in a short period, the operation process is guided to avoid aerosol infection as much as possible;
2) the method helps develop new equipment (a mask or a tracheal cannula and the like), and provides guidance for the design of a human-computer interface by simulating the aerosol transmission condition;
3) the propagation condition of aerosol is simulated when the existing respiration support system is used, the defects are checked, the leakage is repaired, and the existing device is improved.
