Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to an artificial lung branch connecting structure with a fool-proof function.
Background
The inhalation preparation has wide application prospect as an administration mode which can be used for lung targeting and systemic administration. At present, relevant inhalation therapeutic drugs are available for treatment of diseases including asthma, COPD (chronic obstructive pulmonary disease), diabetes and the like at home and abroad, but the imitation stage is still in home. In the process of imitating an inhalation preparation and developing a new drug, the inhalation preparation needs to be evaluated, and an in-vitro evaluation test device guided by the United states FDA and Chinese pharmacopoeia is an NGI (cascade impactor) at present. The structure for in vitro evaluation test by using the cascade impactor comprises: the device comprises an L-shaped connecting pipe, a preseparator, an impactor main body, a clamping component and an air flow outlet, wherein the air flow outlet is connected with a vacuum pump. The agent was introduced into the inlet through the dispersion device and deposited at various locations of the device, and the aerodynamic diameter distribution of the agent was calculated by measuring the deposition amount at each location. The L-shaped connecting pipe is an FDA right-angle throat in the United states, the oral cavity and the throat of a human body are idealized into two circular pipes which are connected at right angles, the structural difference between the two circular pipes and the real human body is quite large, so that ideal oral and throat models are developed at present, but even if the L-shaped connecting pipe is an ideal oral and throat model, only the oral and throat structures of a respiratory system are included, the difference between other respiratory structures such as a main air pipe and a bronchus and the real oral and throat structures of the real human body is not considered, and because the respiratory structures such as different ages, sexes, ethnicities and medical histories are quite large, the ideal oral and throat models cannot represent different crowds; in addition, the same person has different oral cavity volume, tongue position, glottis size and the like under different respiratory states, so that an ideal orolaryngeal model cannot cover the respiratory tract under all different respiratory states. Moreover, the test results of the structure using the conventional in vitro evaluation test using the cascade impactor are merely aerodynamic characteristics of fine particles, and then the preparation lung-entering amount is calculated according to the aerodynamic diameter of less than 5 μm as lung-entering diameter which is generally accepted in the industry. However, in the actual drug particle deposition, particles smaller than 5 μm are likely to be deposited at the oro-laryngeal position and not enter the deep lung, and the structure of in-vitro evaluation test by using a cascade impactor cannot test the deposition amount of the particles at the specific position of the respiratory tract, so that the method has no guiding significance for the evaluation of the inhalation preparation which needs to define the deposition position of the drug preparation.
In view of this, in order to solve the above problems, it is highly desirable to develop a model that can simulate the structure of the respiratory tract of a real human body and can improve the in-vitro and in-vivo correlation, so as to improve the correlation of the in-vitro test results and reduce the cost of inhaled preparation simulated pharmacy and new drug development. The technicians of the company want to develop an artificial lung model according to the real human respiratory tract structure, wherein the artificial lung model comprises all the characteristics of the human respiratory tract structure and comprises the following components: the structures of the oral cavity, the oropharynx, the epiglottis, the larynx, the main bronchus, the bronchus and the like can be used for replacing ideal oropharynx as an inhalation preparation evaluation device; the artificial lung model is reconstructed based on CT data of human respiratory tract, and can realize the tests of respiratory tracts of different people such as age, sex, race, medical history and the like; meanwhile, parameters of the artificial lung model can be adjusted according to different crowds and different respiratory states, and evaluation of inhalation preparations of different respiratory structures can be realized; finally, the technical staff of the company designs the artificial lung model in a detachable and quick-connection mode, so that the accurate measurement of the deposition amount of preparations at different fine parts of the respiratory tract can be realized, and of course, if only a part of the artificial lung is assembled, the quick measurement of a part of the whole part of the assembled artificial lung can be realized, and different test requirements can be met; the artificial lung provided by the technical staff of the company can truly and directly reflect the deposition amount of the inhalation preparation at each position of the respiratory tract, so that the correlation of in-vivo and in-vitro tests is improved. The artificial lung model developed by the technical staff of the company is adopted to carry out medicament imitation evaluation before clinical test and in the development stage, so that development time and cost can be greatly saved, the passing rate of clinical experiments can be improved, and great convenience is provided for enterprises or scientific research.
Specifically, the artificial lung model developed by the technician of the company comprises the following characteristics: oral cavity, oropharynx, epiglottis, larynx, trachea, cricoid cartilage, left main bronchus, tip posterior segment bronchus, anterior segment bronchus, left superior lobe bronchus, superior lingual segment bronchus, inferior lingual segment bronchus, left inferior lobe bronchus, anterior basal segment bronchus, lateral segment bronchus, posterior basal segment bronchus, right main bronchus, right superior lobe bronchus, tip segment bronchus, posterior segment bronchus, right medial lobe bronchus, right inferior lobe bronchus, lateral segment bronchus, medial segment bronchus, lateral basal segment bronchus and medial (cardiac) basal segment bronchus. Sometimes, for different test requirements, the artificial lung model may also include only some of the features thereof, for example, only: oral cavity, oropharynx, epiglottis and model of the mouth and throat. In the artificial lung model, the segmentation is needed from the oropharynx to the bronchus at the rear end, the segmentation principle is that at least one branch needs to be performed as long as a first-stage bronchus is generated, and in the artificial lung model, the total number of the bronchus is 20, so that the number of the segments is at least 20, the number of the segments can exceed 20, and the more deposition positions can be quantitatively measured, the more accurate the test result is; by adopting the method of the segmented model, not only can the deposition amount of each segment be tested, but also the quick-connection segments can be combined for testing.
However, due to the fact that the segmented structure is quite large, the problems that assembly is easy to make mistakes and is troublesome and the air tightness of the whole artificial lung is poor exist, the testing efficiency is reduced, and more importantly, the testing result is inaccurate, so that the method is deviated from the original purpose of designing the artificial lung model.

The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
