Embodiment 1

[0035] Such as Figure 1-5 As shown, a bronchial one-way valve stent includes a stent body 1, a one-way valve 3 is arranged in the stent body 1, and the one-way valve 3 passes through the coating 2 laid on the inner wall of the stent body 1 and the stent body 1. Connection, the bracket body 1 includes a large end bracket section 11, a transition bracket section 12 and a small end bracket section 13 connected sequentially from bottom to top, the large end bracket section 11 and the small end bracket section 13 are all cylindrical in shape, and the transition bracket The segment 12 is conical in shape.

[0036] Working principle: When using the one-way valve stent, the bronchial one-way valve stent is placed in the bronchi of the target lung lobe through a conventional bronchoscope. , open when exhaling, and at the same time drain the secretions at the distal end of the airway, gradually discharge the residual air left in the distal lung lobe of the bronchial one-way valve sten...

Embodiment 2

[0040] Such as Figure 1-10 As shown, on the basis of Example 1, this embodiment gives the preferred structure of the covering film, that is, the covering film 2 includes a large-end film 21, a transition film 22 and a small-end film 23 seamlessly connected sequentially from bottom to top. , the large end film 21 is laid on the bottom of the inner wall of the large end support section 11, the transition film 22 is laid on the upper part of the inner wall of the large end support section 11 and the inner wall of the transition support section 12, and the small end film 23 is laid on the bottom of the small end support section 13 on the inner wall.

[0041] In this embodiment: the film 2 is seamlessly connected to the inner wall of the stent body 1, and the shape of the film 2 is generally consistent with the shape of the stent body 1, which is more conducive to the film 2 being attached to the inner wall of the stent body 1 In this way, the stress of the coating 2 is more unif...

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 ...
