[0018] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiment is only one embodiment of the present invention, not all embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Unless otherwise defined, technical or scientific terms used in the present invention shall have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs.

[0020] This embodiment provides a lung quantitative atomization device.

[0021] Reference Figure 1 A pulmonary quantitative nebulization device includes a ventilator 1, an exhalation connector 2, an inhalation connector 3 and multiple nebulization channels 4.

[0022] Each atomization channel 4 includes an exhalation channel 41, an inhalation channel 42, and a water bath device 43 disposed between the exhalation channel 41 and the inhalation channel 42. The water bath device 43 includes a water bath bottle and a water bath cup disposed within the water bath bottle. The exhalation channel 41 is connected to the lower end of the water bath bottle, and the inhalation channel 42 is connected to the upper end of the water bath bottle, so as to heat the aerosol formed by the atomized drug flowing from the exhalation channel 41 through the inhalation channel 42 in the water bath.

[0023] The expiratory connector 2 is connected to multiple expiratory channels 41, the inspiratory connector 3 is connected to multiple inspiratory channels 42, and the expiratory connector 2 is connected to the expiratory end of the ventilator 1, and the inspiratory connector 3 is connected to the inspiratory end of the ventilator 1. The animals are in an anesthetized state during the experiment. This setting can be used to simulate the breathing movements of the experimental animals during the experiment, thereby assisting in delivering the atomized drugs to the lungs of the experimental animals.

[0024] The ends of the multiple exhalation channels 41 away from the water bath are connected to a nebulizer 5, such as a nebulizer needle, etc. The ends of the multiple inhalation channels 42 away from the water bath are connected to a pulmonary cannula 6, and the ends of the multiple pulmonary cannula 6 away from the inhalation channels 42 are arranged in parallel so as to be inserted into the lungs of the experimental animals.

[0025] When conducting an experiment, the lung cannula 6 is first inserted into the lungs of the experimental animal in a coma, and then the nebulizer 5 is used to supply medicine. With the assistance of the ventilator 1, the atomized medicine heated in the water bath device 43 is delivered to the lungs of the experimental animal and mixed in the lungs, thereby achieving mixed administration of multiple atomized medicines. The effect of mixed administration of multiple atomized medicines at a certain temperature can be judged by the reaction of the experimental animal.

[0026] During actual use, the water bath device 43 can also be replaced by other related regulating devices that can adjust the drug administration environment, such as a diffusion dryer for adjusting the humidity, which is used to conduct experiments on the mixed administration effects of multiple atomized drugs under different humidity conditions; according to experimental needs, multiple regulating devices can also be connected in series to study the mixed administration effects of multiple atomized drugs under multiple drug administration environments.
