Abstract

The invention relates to the technical field of one-way valve stent, in particular to a bronchus one-way valve stent which is used for solving the problems that in the prior art, because of its limitation, a one-way valve stent is easy to deform and can not be restored in the working process, and the service life is short. The bronchus one-way valve stent provided by the invention comprises a stent body, a one-way conducting valve and a covering film, the stent body comprises a large-end stent section, a transition stent section and a small-end stent section which are sequentially connected from bottom to top, the large-end stent section and the small-end stent section are both cylindrical, and the transition stent section is conical. The large-end stent section and the small-end stent section are connected through the transition stent section, during use, the transition section can effectively prevent the whole stent body from forming rigid connection and difficult restoring the after deformation, so that the force on the the large-end stent section, the small-end stent section and the whole covering film can be effectively buffered and balanced, therefore, the performance and the service life of the one-way valve stent can be effectively improved.

Description

technical field

[0001] The invention relates to the technical field of one-way valve support, and more particularly relates to a bronchial one-way valve support. Background technique

[0002] Chronic obstructive pulmonary disease (COPD) is a common chronic airway disease, usually including chronic bronchitis and obstructive emphysema, mainly manifested as irreversible chronic airway obstruction and lung hyperinflation, pathological Lung parenchyma manifests as emphysema. COPD is currently the fourth leading cause of death in the world, and as many as 600 million patients suffer from COPD every year. According to population surveys in some areas of my country, the prevalence of COPD accounts for 8.2% of people over 40 years old. According to the forecast of the World Bank / World Health Organization, by 2020, COPD will rank fifth in the world's economic burden of disease and third in the cause of death. Obstruction and lung hyperinflation, severe cases can be treated with home ...
