Embodiment Construction

[0026] Referring to Fig. 1 and Fig. 2, it is a check valve shape structure. The valve body consists of 3 (or 4, 5, etc.) Tail-shaped elastic fixing hook 3 with barbs, valve body frame support rod 5 is fixed on the valve body frame; the bag opening of membrane bag type one-way valve 4 is intermittently fixed on the outer ends of elastic support rods 1 and 2 skeletons The bag body covers and is fixed on the outside of the elastic struts 1, 2, and can be stretched by the elastic struts 1, 2 to form a one-way valve in the trachea, which can ensure the one-way flow of gas and liquid. Valve body frame and its fixing structure, valve body frame support stable seat are all made of nickel-titanium alloy memory metal material etc., can be compressed and be placed in the conveyer flexible pipe 7 and can open the shape shown in Fig. 1, Fig. 2 again. The bag-type soft film is made of medical silica gel, medical polyester film and other materials. Through the biopsy hole of the bronchoscop...

Abstract

The present invention belongs to the field of medical valve device technology. The intratracheal non-return valve includes a non-return valve, an elastic valve holder and its fixture structure as well as a valve holder supporting seat. The intratracheal non-return valve is set inside bronchus and has the features of convenient setting, fixing and use, simple structure, good treating effect, no side effect, wide clinic application range, etc.

Description

technical field [0001] The invention relates to the technical field of valves or valve devices that are particularly suitable for medical use, in particular to a one-way valve device that is suitable for implanting in the segment of the lung rake area or the bronchus below the segment. Background technique [0002] At present, in the treatment of emphysema, bullae, chronic obstructive pulmonary disease, etc., internal medicine mainly focuses on anti-infection, bronchiolar expansion and other symptomatic treatment measures, which cannot be cured and the curative effect is poor. Lung volume reduction surgery is the main method of surgery. Because patients with poor lung function often cannot tolerate surgery and have a high mortality rate, the application of surgery is limited. The inventor of the present application once invented "a kind of one-way valve device in the trachea", the patent publication number is CN2749468, and its structure is a cylindrical overcoat, and a semi...
