Detailed Description

The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.

A tracheal cannula structure as shown in fig. 1 to 3, which comprises an outer cannula 1 and an inner cannula 2, wherein the top of the outer cannula 1 is fixedly connected with the bottom of the inner cannula 2, a breathing channel is reserved in the middle, an air inlet 11 is arranged at the top of the outer cannula 1, a first cover 3 is movably embedded at the air inlet 11, a first protrusion 31 is arranged on the inner side surface of the first cover 3, and the first protrusion 31 is embedded in the air inlet 11; in addition, a sputum suction port 12 is convexly arranged on the side wall of the outer sleeve 1 and is communicated with a channel for internal breathing; when the sputum suction port is used, a closed sputum suction pipe can be connected, when the sputum suction port is not used, a second cover body 4 is arranged at the position of the sputum suction port 12 in a sealing mode, for the purpose of convenience in use and prevention and treatment of the loss of the second cover body, a connecting piece 6 is arranged between the second cover body 4 and the sputum suction port 12, one end of the connecting piece 6 is fixedly connected with the side wall of the second cover body 4, and the other end of the connecting piece is fixedly connected with the side wall of the sputum suction port 12; therefore, when the sputum is sucked, the second cover body is pulled out of the sputum sucking port and then suspended in the air under the action of the connecting piece, so that the second cover body can be prevented from being lost, and the probability of pollution caused by random placement of the second cover body can be reduced;

meanwhile, the air inlet 11 is provided with the filter element 5, and the filter element 5 is fixedly provided with the filter screen 51, so that the condition of mistaken suction of dust, foreign matters and winged insects can be effectively prevented through the filter screen; furthermore, when the device is used, a patient may have a cough, the filter screen is easily polluted after cough and expectoration, in order to replace the filter screen in time, the top of the outer sleeve 1 is provided with the external thread 13, the inner side surface of the bottom of the filter element 5 is provided with the internal thread 52, the external thread 13 and the internal thread 52 are meshed with each other in daily use, so that the sealing performance of the structure is ensured, and when the filter element needs to be replaced, the filter element is directly screwed down for replacement;

furthermore, in the process of preparing to pull out the tracheal cannula from the trachea, one end of the tracheal cannula, which is positioned outside the patient body, needs to be blocked by a blocking pipeline object so as to enable the patient to adapt to mouth and nose breathing, but once the blocking pipeline object falls off, the tracheal cannula is polluted, and the continuous use is influenced; therefore, a groove 53 is arranged at one end part of the filter element 5 far away from the outer sleeve 1, a second bulge 32 is arranged on the inner side surface of the first cover body 3, when the functional exercise is carried out, the second bulge 32 can be embedded in the groove 53, so that the whole air inlet is sealed, if uncomfortable feeling is generated and the user feels stuffy during the exercise, the first cover body can be taken down from the filter element, and the breathing of the throat is recovered; the structure does not influence the daily normal use;

in addition, in order to meet the sanitary requirement of the used tracheal tube, the inner side surfaces of the inner tube 2, the outer tube 1 and the filter piece 5 are covered with silver-loaded nano silicon dioxide antibacterial coatings; the silver-loaded nano silicon dioxide is a high-efficiency antibacterial active material, and can be used as a carrier to adsorb metal antibacterial ions because the nano silicon dioxide has extremely strong surface activity, and the silver ions have strong killing effect on pathogenic bacteria, so that when the silver-loaded amount is 1-2%, the killing rate on escherichia coli and staphylococcus aureus can reach 100%, and the silver-loaded nano silicon dioxide is harmless to a human body.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
