The main body 2 can be a soft annular structure, and the permeable layer 3 can be a sponge layer or a cotton layer. The outer wall is pressed to deform it to squeeze the lubricating body 4, and then the lubricating body 4 is infiltrated into the permeable layer 3 and coated on the outside of the tube wall of the nasopharyngeal airway 1 during the process of extracting the nasopharyngeal airway 1. When the medical staff takes out the nasopharyngeal airway 1, the lubrication step is completed and it can be used, avoiding the lubricating body 4 from getting on the hands and affecting the operation. The operation process is convenient and fast. The lubricating body 4 is a lubricating oil layer or a bag filled with a lubricant.

[0025] Please refer to Figure 2 as well as Figure 3 As shown, specifically, the body 2 includes an inner shell 5 sleeved on the outer wall of the nasopharyngeal airway 1 and an outer shell 6 ringed on the outside of the inner shell 5, the inner shell 5 and the outer shell 6 are sealed and connected at both ends of the top and the bottom to form a receiving chamber 7, the inner shell 5 is sleeved on the outer wall of the nasopharyngeal airway 1, the outer shell 6 is a soft shell structure, the permeable layer 3 is fixedly arranged on the inner wall of the inner shell 5 on one side close to the nasopharyngeal airway 1, the surface of the inner shell 5 corresponding to the receiving chamber 7 is provided with a permeate port 8, a lubricant 4 is placed in the receiving chamber 7, the lubricant 4 is preferably a bag filled with lubricant, and when needed, it can be in the bag The outer shell 6 is squeezed in the sealed bag containing the nasopharyngeal airway 1 to rupture the bag containing the lubricant in the accommodating cavity 7, and the lubricant flows to the permeable layer 3 through the permeable port 8. After the permeable layer 3 is infiltrated, the lubricant is coated on the tube wall of the nasopharyngeal airway 1 during the process of the medical staff drawing out the nasopharyngeal airway 1. The operation is simple and fast, and the lubricant is prevented from getting on the hands. The inner shell 5 is preferably a hard shell structure, which allows the lubricant 4 to flow out of the permeable port 8 more quickly. The lubricant 4 is preferably a bag containing a lubricant, so that the lubricant can be stored separately, ensuring the dryness of the nasopharyngeal airway 1 before use.
[0026] Please refer to Figure 2 as well as Figure 3 As shown, specifically, the inner shell 5 is a hard shell structure, which makes the overall shape of the main body 2 more stable.
[0027] Please refer to Figure 2 as well as Figure 3 As shown, specifically, the accommodating cavity 7 includes a first cavity 9 and a second cavity 10, the first cavity 9 and the second cavity 10 are internally connected, the first cavity 9 surrounds the outer surface of the shell 6, the second cavity 10 protrudes from the outer surface of the first cavity 9, the lubricating body 4 is placed in the second cavity 10, and the number of the second cavity 10 can be determined according to specific needs. Preferably, two are symmetrically arranged. When in use, the outer wall of the second cavity 10 is squeezed by fingers to break the internal lubricating body 4 and the lubricant flows out. The lubricant is first dispersed in the first cavity 9 and the second cavity 10. Since the first cavity 9 and the second cavity 10 are both surrounded by the outer surface of the shell 6, the lubricant flows to the permeation layer 3 through the permeation port 8. After infiltrating the permeation layer 3, the lubricant is coated on the wall of the nasopharyngeal airway 1 during the process of medical staff drawing out the nasopharyngeal airway 1. The operation is simple and fast, and the lubricant is prevented from getting on the hands.

When in use, the medical staff can directly squeeze the outer shell 6. In the process of squeezing the outer shell 6, the tip of the spur 11 moves toward the inner shell 5 and then punctures the lubricating body 4, so that the lubricant inside the lubricating body 4 flows out, and the lubricant infiltrates the permeable layer 3 through the permeation port 8 and contacts the tube wall of the nasopharyngeal airway 1. Lubrication is quickly completed in the process of drawing out the nasopharyngeal airway 1, saving operation time and avoiding the lubricant from getting on the hands.
[0029] Please refer to Figures 2 to 4 As shown, specifically, the lubricating body 4 is a bag filled with lubricant so that the lubricant can be stored separately, thereby ensuring that the nasopharyngeal airway 1 is dry before use.

When in use, the medical staff squeezes the outer shell 6 with their fingers and then squeezes the permeable layer 3. Since the permeable layer 3 is infiltrated with the lubricating oil, the lubricating oil seeps out from the permeate port 8 after squeezing, and then as the nasopharyngeal airway 1 is extracted, the lubricant is coated on the outer wall of the pipeline, and the permeable layer 3 is placed in the accommodating chamber 7, so that the lubricating oil is received to prevent the lubricant from seeping out from the permeate port 8 when not in use.
