DETAILED DESCRIPTION
[0020] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described in detail below. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of the present application.
[0021] Referring to Figures 1-4The utility model provides a kind of improved nasal tracheal tube that can prevent nasal pressure injury, including conduit 1, gasbag 2 is movably sleeved on the outside of conduit 1 along its length direction, in actual application, the shape of gasbag 2 is annular sleeve, one end of gasbag 2 is fixedly provided with moving push plate 4 for pushing it to move on conduit 1, moving push plate 4 is provided with air guide pipe structure 3 for inflating and deflating gasbag 2.Through the above specific structure design, since gasbag 2 is soft, plus friction, it is inconvenient to move gasbag 2, and moving push plate 4 makes it convenient and labor-saving to adjust gasbag 2.
[0022] see the accompanying drawings Figure 1 and 4 As shown, the shape of moving push plate 4 is round plate body, and a guide hole is formed in the center of moving push plate 4 for sliding through conduit 1. A ring sleeve 402 is fixedly arranged in the guide hole, and the outer side of the ring sleeve 402 is in the shape of a tapered body with one wide end and one narrow end. The ring sleeve 402 can support the inner side of the gasbag 2, which can better push the gasbag 2. The wide end of the ring sleeve 402 is fixedly connected with the moving push plate 4, and the gasbag 2 is fixedly arranged on the outer side of the ring sleeve 402. A notch 401 is formed in one side of the moving push plate 4. In actual application, the notch 401 can make the moving push plate 4 more conveniently close to the nostril of the patient.
[0023] see the accompanying drawings Figure 3 As shown, the air guide pipe structure 3 includes an air guide pipe 301, one end of the air guide pipe 301 passes through the moving push plate 4 and is connected with the gasbag 2, and the other end of the gasbag 2 is connected with an inflation tube joint 302. An end cap 304 is detachably arranged on the inflation tube joint 302, and the end cap 304 and the inflation tube joint 302 are fixedly connected with each other through a connecting belt 303. The end cap 304 is provided with a sealing plug 305 for sealing the inflation tube joint 302, and one side of the end cap 304 is fixedly provided with a protrusion 306.
[0024] Working principle:
[0025] After the intubation operation of the conduit 1 is completed, the gasbag 2 is moved to the place where the conduit 1 contacts the entrance of the nasal cavity through the moving push plate 4, and an appropriate amount of air is injected into the gasbag 2 through the inflation tube joint 302 of the air guide pipe structure 3 by using a 1ml syringe until the gasbag fills the position where the nasal cavity contacts the tracheal tube, which ensures that the gasbag fully contacts the nose, thereby avoiding damage caused by the direct contact of the tracheal tube with the nose due to the relatively hard material of the tracheal tube. After inflation is completed, the syringe is removed, and the inflation tube joint 302 is sealed by the end cap 304 and the sealing plug 305. In addition, when the gasbag 2 is detached, the end cap 304 and the sealing plug 305 are removed, and the air is released through the air guide pipe 301.
[0026] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
