Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Base ring and tubular liner
Integrative connection between base ring and the tubulose liner, tubulose liner are to cup joint the form and are connected with the base ring, and the diameter size of tubulose liner differs promptly, by the diameter of cup jointing structure interior to outer tubulose liner increase gradually.
In an assembly state, the tubular gasket which is not hermetically arranged between the port of the tracheal cannula and the inner tube of the voice valve is bent or folded and is positioned between the end surface of the voice valve and the tracheal cannula or between the inner tube and the outer tube of the voice valve.
The elasticity of the material can cause the folded or bent tubular gaskets to exert separation acting force on the end faces of the inner tube of the voice valve, and the intervals of the tubular gaskets are used for matching with the wall thickness of the inner tube of the voice valve so as to reduce the separation acting force.
First convex ring
First bulge loop helps increasing the effective area of contact of base ring and tracheal cannula port, improves the stability that base ring and tracheal cannula port are connected.
Second convex ring
The second raised ring may be provided on the outer surface of the tubular liner alone, or on the inner surface of the tubular liner alone, or on both the inner and outer surfaces of the tubular liner. The thickness of the tubular spacer is usually 0.5 to 2 mm. The ratio of the height of the second convex ring to the thickness of the tubular gasket is (0.2-0.5): 1.
The first tubular liner is adjacent to the second tubular liner and the second tubular liner is sleeved outside the first tubular liner, and a second convex ring is arranged on the outer surface of the first tubular liner and the inner surface of the second tubular liner and can prevent the relative displacement of the first tubular liner and the second tubular liner during the process of inserting the tracheal cannula port into the inner tube of the voice valve.
The second convex ring on the outer surface of the tubular liner further increases the static friction area and the static friction force with the inner tube of the voice valve, and reduces the probability that the voice valve is separated from the port of the tracheal tube.
The included angle between the second convex ring and the outer surface of the free end cylinder section of the tubular liner is an obtuse angle larger than 150 degrees, which is helpful for guiding the tracheal cannula port coated with the tubular liner to be more smoothly plugged into the inner tube of the voice valve.
