[0049] Please refer to the attached Figure 1-3 , the embodiment shown in the figure is a tracheostomy tube blocking device, comprising: a tracheostomy tube body 10, the tracheostomy tube body 10 is used to be fixed relative to the patient's neck, and a body through hole 101 is provided in the middle of the tracheostomy tube body 10; a cannula 11, which is arranged on the side of the tracheostomy tube body 10 facing the neck, and the cannula 11 is connected with the body through hole 101, and a connecting tube 32 is arranged on the side of the tracheostomy tube body 10 facing away from the neck, and the connecting tube 32 is connected with the body through hole 101; an adjusting mechanism, The device comprises an adjusting box 31 and an adjusting wheel 34. The connecting tube 32 is inserted into one end of the adjusting box 31 and exits from the other end. The adjusting box 31 comprises a bottom wall and a side wall. The connecting tube 32 is arranged between the bottom wall and the adjusting wheel 34. The side wall is used to limit the movement of the adjusting wheel 34 in a direction parallel to the length of the connecting tube 32. When the adjusting wheel 34 moves to different positions, the distance from the bottom wall is different, so that the adjusting wheel 34 can clamp or loosen the connecting tube 32. Fixing holes are also provided at both ends of the tracheostomy tube body 10 to facilitate the passage of the strap so that it can be better fixed on the patient's neck. Figure 2 and Figure 3 It can be seen that the extending direction of the connecting tube is the length direction of the adjusting box 31, and is also the moving direction of the adjusting wheel 34. Since the distance between the adjusting wheel 34 and the bottom wall is different when it moves to different positions, the clamping degree of the connecting tube 32 by the adjusting wheel 34 is different when it moves to different positions, and finally the technical effect of adjusting the air flux or blocking the connecting tube can be achieved.

[0050] In one embodiment of the present application, a rotating rod 36 is disposed on the axis of the adjusting wheel 34, and a slide groove 35 is also disposed on the inner side of the side wall. The slide groove 35 is disposed parallel to the length direction of the connecting tube 32, and the rotating rod 36 is adapted to the slide groove 35. Figure 2It can be seen that a rotating rod 36 is protruding outward from the bottom surface of at least one side of the adjusting wheel 34, and a sliding groove 35 is provided inside the side wall of at least one side of the adjusting box 31. The direction of the rotating rod 36 is parallel to the axis direction, and the rotating rod 36 can move or rotate in the sliding groove 35. By providing the rotating rod 36 and the sliding groove 35, the moving track of the adjusting wheel 34 can be stabilized, so that the adjusting wheel 34 is not easy to fall out.

[0051] In a further embodiment, both bottom surfaces of the adjusting wheel 34 are provided with rotating rods 36 protruding outward, and the side walls on both sides of the adjusting box 31 are provided with sliding grooves 35. In a specific embodiment, the rotating rods 36 are protrudingly provided on both bottom surfaces of the adjusting wheel 34, and the inner sides of both side walls of the adjusting box 31 are provided with sliding grooves 35. By providing the sliding grooves 35 on both sides to fix the adjusting wheel 34, the stability of the adjustment wheel 34 and the adjusting box 31 can be further improved, and it is less likely to fall out.

[0052] As a specific example, Figure 1 As shown, it also includes a mouthpiece 12, which is funnel-shaped, one end of which is connected to the main body through hole 101, and the mouthpiece 12 is arranged on the side of the tracheostomy tube body 10 facing the neck; a sleeve 33, which is sleeved on the other end of the mouthpiece 12, and the sleeve 33 is also connected to the connecting pipe 32. In some embodiments, the mouthpiece 12 can also be made by integrally molding with the main body through hole 101, so as to facilitate use. In other embodiments, the conical part of the mouthpiece 12 can be made of elastic components such as rubber, and can also be set as a component that can be telescopically adjusted in length. The sleeve 33 is used to be fastened to the mouthpiece 12, and plays the role of airtightly connecting the main body through hole 101 and the connecting pipe 32. The above design can easily replace the connecting pipe 32 structure to ensure the cleanliness and hygiene of this design.

[0053] In some specific embodiments, the sleeve 33 is made of rubber material. The rubber material is elastic, has strong plasticity and air tightness, and can well cover the mouthpiece 12, so as to better achieve the technical effect of airtight connection of the mouthpiece 12.

[0054] In some specific embodiments, the sleeve 33 is made of a plastic film. The sleeve 33 is selected to be a plastic film with strong elasticity, which can well cover the mouthpiece 12 and better achieve the technical effect of airtight connection with the mouthpiece 12.

[0055] For other embodiments of this application, please continue to refer to Figure 1The device is also provided with an elastic clip 40, which is used to clamp the outside of the sleeve 33. The shape of the clamping portion of the elastic clip 40 can be designed to be compatible with the sleeve mouth 12, such as being designed to be a similar arc shape. By clamping the sleeve 33 with the elastic clip 40, the airtightness of the sleeve 33 and the sleeve mouth 12 can be better ensured.

[0056] In order to achieve the technical effect of adjusting the flux of the connecting pipe, please refer to Figure 3 The bottom wall of the regulating box 31 is tilted, and the slide groove 35 is kept substantially horizontal, so that the distance between the regulating wheel 34 and the bottom wall is different when the regulating wheel 34 moves to different positions, thereby ultimately achieving the technical effect of regulating the flux of the connecting pipe or blocking the connecting pipe.

[0057] In one embodiment of the present application, the upper edge of the side wall is folded inward to form a limit card plate, and the limit card plate is used to limit the movement of the adjusting wheel 34 in a direction parallel to the length of the connecting pipe 32. The limit card plate is tilted in the horizontal direction, so that the distance between the adjusting wheel 34 and the bottom wall is different when it moves to different positions. Specifically, the limit card plate can limit the height of the adjusting wheel 34. The limit card plate is tilted, with one end close to the bottom wall and the other end far from the bottom wall, so that when the adjusting wheel 34 moves to different positions in the horizontal direction, it can clamp the connecting pipe, thereby ultimately achieving the technical effect of adjusting the flux of the connecting pipe 32 or blocking the connecting pipe 32.

[0058] In some further embodiments, an airbag 22 is provided outside the cannula 11, and the airbag 22 is communicated with the airbag tube 21, and the airbag tube 21 is used to inflate the airbag 22. By providing the airbag 22, when the airbag 22 is in a non-inflated state, upper airway ventilation can be restored, and when the airbag 22 is inflated and the connecting tube is not blocked, breathing can be performed through the cannula, which can achieve the technical effect of adjusting the airway as needed.

[0059] In some comprehensive embodiments, when using the device, the cannula 11 is inserted into the trachea connected to the neck incision, the tracheostomy tube body 10 is fixed to the patient's neck by using a restraint belt, and then the airbag 22 is inflated through the airbag tube 21 to fill the gap between the cannula 11 and the trachea. At this time, the preliminary work when using the device can be completed; at this time, the connecting tube 32 is connected to the patient's trachea, and air can be supplied through the connecting tube 32 for the patient's breathing. When the connecting tube 32 is blocked in the later stage in order to allow the patient to remove the tracheal tube 33 as soon as possible and restore upper respiratory tract ventilation, the gas in the airbag 22 is released in advance, so that there is a gap between the cannula 11 and the trachea. At this time, the adjusting wheel 34 can be pushed to squeeze the connecting tube 32, thereby achieving the blocking of the connecting tube 32. In addition, the device can also achieve different degrees of blocking, so that the degree of blocking can be selected according to the patient's condition, thereby improving the practicality of the device.

[0060] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described in this article, or equivalent structural or equivalent process changes made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the utility model patent.
