Specifically, the two supporting bars 121 are arranged crosswise, and the axes are perpendicular to each other. Support bar 121 has improved the area of contact when upper tube section 120 is connected with cover plate 130 effectively, and then has improved the steadiness of connecting effectively.
In an embodiment of the present invention, the top end of each supporting bar 121 has a second threaded hole, and correspondingly, the two straight sides of each cover plate 130 have second threaded holes respectively. The supporting bar 121 and the cover plate 130 are fixedly connected through the second screw holes using second screws.
In another embodiment of the present invention, a third clamping groove is formed on the top end of each supporting bar 121, and correspondingly, a second clamping bar is respectively disposed on the bottom end of each cover plate 130 on two straight sides. The supporting bar 121 and the cover plate 130 are fixedly connected by the second clamping bar and the third clamping groove.
In one embodiment of the present invention, the axial length of the lower tube section 110 is less than the axial length of the upper tube section 120. Specifically, the axial length of the lower tube segment 110 is less than 2cm. Therefore, the pipe blocking device is not easy to fall off from the tracheostomy catheter, and the smoothness of ventilation of the pipe blocking device is guaranteed.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can equally replace or change the technical solution and the inventive concept of the present invention within the scope of the present invention.
