Novel artificial alveolar model

Abstract

In order to solve the problems that an artificial lung model cannot be directly connected to a simulated respirator, a test structure is low in reliability, and the working efficiency is reduced due to the huge number of pulmonary alveoli clusters, the invention provides a novel artificial alveolar model that is characterized by comprising an upper end cover 1, a sealing washer 2, a supporting net3, a filter membrane 4 and a lower end cover 5; the upper end cover 1 comprises a handle convenient to take, an upper cover body and a first sealing rib 12; the handle is located above the upper cover body, the lower surface of the upper cover body is a plane, and the first sealing rib 12 is located at the position, close to the outer side edge, of the lower surface of the upper cover body; the lower end cover 5 comprises a lower cover main body, a second sealing rib 52, a bottom air path 53 and a connector 55; a containing cavity is formed in the lower cover main body, the bottom air path 53is arranged in the containing cavity, a through hole is formed in the center of the lower cover main body, the connector 55 penetrates through the interior of the through hole, the connector 55 is athrough cylindrical through hole, and the connector 55 extends in the direction away from the containing cavity of the lower cover main body.

Description

technical field [0001] The present invention relates to the technical field of medical devices, more specifically, the present invention relates to a novel artificial alveolar model, the artificial alveolar model adopts a new structure at the last stage to simulate the collection of drug deposition by the alveoli, the collection device It can simultaneously meet the breathing, inhaling and exhaling modes in the artificial lung test, and improves the test range and accuracy of the artificial lung manufactured based on the real human respiratory tract in the field of inhalation preparation evaluation testing. Background technique [0002] With the development of in vitro testing and evaluation of inhalation preparations, more and more attention has been paid to artificial lungs based on real human respiratory tracts. Although the current in vitro testing of inhalation preparations is still based on the cascade impactor (NGI) specified in the Pharmacopoeia, the bionic artificia...

AI Technical Summary

Problems solved by technology

[0005] In view of this, in order to solve the problems that the artificial lung model cannot be directly connected to the simulated ventilator, the reliability of the test structure is low, and the work efficiency is reduced due to the huge number of alveolar clusters, the present invention proposes a new artificial alveolar model, It simplifies the alveolar structure and simplifies the alveoli into a drug collection plate, which can realize the collection and testing of drug powder and make the test results of artificial lungs more reliable
