The left end of the hole plug 31 is a closed structure, and the right end of the hole plug 31 communicates with the inside of the sealing cover 1. The side wall of the hole plug 31 is divided into a ventilation part and a sealing part. A plurality of air holes 32 are uniformly and penetratingly provided on the ventilation part. A sealing ring is sleeved outside the sealing part, and the sealing part forms a sliding sealing fit with the through hole 2 through the sealing ring; the power component includes a hollow connecting cylinder 41, a left fixing plate 42, a right fixing plate 43, a guide rod 44, a threaded rod 45, a handle 46, a moving block 47 and a connecting rod 48. The hollow connecting cylinder 41 is a hollow cylindrical barrel made of transparent material. The right end of the hollow connecting cylinder 41 is threadedly connected to the left end of the sealing cover 1. The left inner part of the hollow connecting cylinder 41 is fixedly provided with a left fixing plate 42 and a right fixing plate 43. The left fixing plate 42 and the right fixing plate 43 are both provided with a plurality of ventilation holes for ventilation. A graduated guide rod 44 is fixedly connected between the left fixing plate 42 and the right fixing plate 43. The guide rod 44 is above the threaded rod 45 and the guide rod 44 is arranged parallel to the threaded rod 45. The left and right ends of the threaded rod 45 are respectively rotatably connected to the left fixing plate 42 and the right fixing plate 43 through bearings, and the left end of the threaded rod 45 passes through the left fixing plate 42 and is fixedly connected to the handle 46.

[0021] It can be understood that in implementation, the hollow connecting cylinder 41 can be made of transparent medical plastic material, which is convenient for observing the graduated guide rod 44, and the precise position of the control component can be judged by observing the scale.

[0022] Further, the plug body has a conical structure, the top of the plug body is in sealed threaded connection with the bottom of the sealing cover 1, and a ventilation hole is also provided in the middle of the plug body. The top end of the ventilation hole is in conduction connection with the inside of the sealing cover 1.

[0023] It can be understood that in implementation, the plug body can be made of silicone material with a conical structure. A rope-passing hole is provided at the right end of the side wall of the sealing cover 1, and a hanging rope is arranged in the rope-passing hole. During use, it can be connected to one side of the tracheotomy cannula to ensure the stability of the plugging device during use and prevent it from falling off. This is prior art and will not be elaborated here.

[0024] Further, a filter screen 5 is arranged at the right inner end of the hole plug 31. The outer edge of the filter screen 5 is adhesively bonded to the inner wall of the hole plug 31, and a disinfectant is provided on the filter screen 5.

[0025] It can be understood that in implementation, the filter screen 5 can be made of non-woven fabric material, and alcohol or chlorine dioxide can be used as the disinfectant for disinfection.

[0026] Further, the ventilation part is located in the middle of the side wall of the hole plug 31. Both the left and right parts of the side wall of the hole plug 31 are sealing parts, and the transverse lengths of both the sealing part and the ventilation part are the same as the transverse length of the through hole 2.

[0027] It can be understood that the sealing part is used to block the through hole 2, and the ventilation part is used to relieve the blockage of the through hole 2. In practice, clamping parts for preventing the hole plug 31 from slipping are fixedly arranged at the left and right ends of the side wall of the hole plug 31.

[0028] For the working principle, please refer to Figure 1 - Figure 2 As shown, when the patient needs to block the tube, the bottom end of the plug body abuts against the opening of the tracheal cannula, and then the handle 46 is manually rotated to drive the threaded rod 45 to rotate forward and backward. When the threaded rod 45 rotates forward, it drives the moving block 47 to approach the right fixing plate 43. When the moving block 47 approaches the right fixing plate 43, it will drive the connecting rod 48 and the hole plug 31 to move to the right. During the process of the hole plug 31 moving to the right, it will gradually block the through hole 2 until it is completely blocked. When the threaded rod 45 rotates backward, it drives the moving block 47 to move away from the right fixing plate 43. When the moving block 47 moves away from the right fixing plate 43, it will drive the connecting rod 48 and the hole plug 31 to move to the left. Due to the existence of multiple air holes 32 in the ventilation part, during the process of the hole plug 31 moving to the left, it will gradually relieve the blockage of the through hole 2 until it is completely relieved. Generally speaking, the graduated guide rod 44 can be observed, and the control component is driven by the power component to move precisely left and right to adjust the blockage amount of the through hole 2, that is, by gradually adjusting the gas flow rate entering the trachea, the patient can have an adaptation process, reducing the discomfort of the patient during the tube blocking process.
