Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a tracheostomy tube plugging cap. Background Technology

[0002] Tracheostomy is a common surgical procedure widely used for patients experiencing respiratory distress due to airway obstruction, neuromuscular diseases, or other factors. The procedure involves inserting a tracheostomy tube through a tracheotomy incision in the patient's neck, allowing air to enter the lungs directly through the trachea, thus ensuring an open and unobstructed airway. After a tracheostomy, patients typically require respiratory support via the tracheostomy tube. As the patient recovers, they gradually transition to spontaneous breathing. However, this transition from tracheostomy tube-dependent breathing to fully spontaneous breathing usually requires a gradual process, necessitating a precise airflow regulation mechanism to help the patient gradually adapt and regain upper airway breathing capacity. Existing fully enclosed endotracheal caps cannot regulate the airflow path, leading to sudden changes in the patient's breathing pattern within a short period, which can easily cause breathing difficulties, anxiety, and airway pressure discomfort.

[0003] The utility model patent with publication number CN217794046U discloses a tracheostomy tube plugging cap, including a cap body with a closed end and an open end at both ends. The closed end of the cap body has several ventilation holes, and a cover plate is provided above the closed end. Several blocking posts for blocking the ventilation holes are provided on the side wall of the cover plate facing the closed end. The lengths of adjacent blocking posts are different. This utility model uses blocking posts of different lengths to enter the corresponding ventilation holes and block the corresponding ventilation holes, thereby changing the sealing area of ​​the cap body on the tracheostomy tube so that medical staff can adjust the sealing area of ​​the cap body on the tracheostomy tube according to the patient's breathing. However, this protective device still has the following problems when in use: (1) Although the plugging cap can adjust the airflow to a certain extent, it cannot finely adjust the airflow channel; (2) The plugging cap is easy to change the airflow after accidental contact. Summary of the Invention

[0004] To address the aforementioned problems, the tracheostomy cannula plug of this invention achieves precise airflow regulation by incorporating an airflow adjustment mechanism. Simultaneously, the design of the first and second engagement teeth ensures the adjustment mechanism is stably held in the set position. Furthermore, after the adjustment valve is pulled out, two limiting mechanisms, through the cooperation of trapezoidal blocks and springs, limit the two engagement teeth, ensuring that the two rotating shafts no longer rotate.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A tracheostomy tube plugging cap includes a plugging cap body, a baffle for sealing the trachea is rotatably provided inside the plugging cap body, and an airflow regulating mechanism for adjusting the rotation angle of the baffle is provided through the side of the plugging cap body, the airflow regulating mechanism is provided with a first limiting mechanism and a second limiting mechanism.

[0007] Furthermore, the airflow regulating mechanism includes a regulating valve, a first rotating shaft, and a second rotating shaft; the first rotating shaft is movably connected to the main body of the plug cap, the second rotating shaft is rotatably connected to the main body of the plug cap, and the second rotating shaft is connected to a baffle; the first rotating shaft and the second rotating shaft are detachably connected.

[0008] Furthermore, the first rotating shaft has a first engagement tooth connected to the end away from the regulating valve, and the second rotating shaft has a second engagement tooth that cooperates with the first engagement tooth at the end near the first rotating shaft.

[0009] Furthermore, the first biting tooth is provided with a first limiting mechanism that cooperates with it; the first limiting mechanism includes a first annular base, and the first base is provided with a plurality of first trapezoidal blocks that match the first biting tooth, and the first trapezoidal blocks are connected to the first base by a first spring.

[0010] Furthermore, the first trapezoidal block has an inclined surface at one end near the first rotating shaft, and the narrow end of the inclined surface faces the center of the first base.

[0011] Furthermore, the second biting tooth is provided with a second limiting mechanism that cooperates with it.

[0012] Furthermore, an angle display panel is provided between the airflow regulating mechanism and the main body of the plug cap.

[0013] The beneficial effects of this utility model are:

[0014] 1. The tracheostomy cannula plug of this utility model achieves precise airflow regulation through the inclusion of an airflow adjustment mechanism. The combined use of the regulating valve and the rotating shaft allows for precise control of the airflow according to the patient's needs. Simultaneously, the design of the first and second engagement teeth ensures the adjustment mechanism is stably held in the set position. Furthermore, after the regulating valve is removed, two limiting mechanisms, through the cooperation of a trapezoidal block and a spring, limit the first and second engagement teeth, ensuring that the two rotating shafts no longer rotate.

[0015] 2. The tracheostomy cannula plug cap of this utility model can achieve precise airflow regulation by setting an airflow adjustment mechanism. Utilizing the cooperation between the regulating valve and the rotating shaft, the user can precisely control the airflow through the tracheostomy cannula plug cap according to the patient's needs, ensuring better adaptation for the patient when transitioning to spontaneous breathing.

[0016] 3. The design of the first and second meshing teeth ensures that the airflow regulating mechanism can be stably held in the set position. Furthermore, after the regulating valve is pulled out, the trapezoidal block, through spring action, engages with the grooves of the two meshing teeth, limiting the movement of the two rotating shafts. This prevents accidental rotation of the regulating valve after it is pulled out, which could lead to inaccurate angle display. It also prevents the second rotating shaft from continuing to rotate after reaching the predetermined angle, ensuring the regulating valve remains stable at the set airflow rate and preventing over-adjustment or instability.

[0030] Example 1

[0031] See attached document Figure 1-9 The tracheostomy tube plugging cap shown includes a plugging cap body 1, a baffle 24 for sealing the trachea is rotatably provided inside the plugging cap body 1, and an airflow regulating mechanism 2 for adjusting the rotation angle of the baffle 24 is provided through the side of the plugging cap body 1. The airflow regulating mechanism 2 is provided with a first limiting mechanism 4 and a second limiting mechanism 5.

[0032] By incorporating the airflow adjustment mechanism 2, the airflow balance inside and outside the tracheostomy tube cap can be easily adjusted. The airflow adjustment mechanism 2 can regulate the airflow according to the patient's needs, thereby controlling the patient's respiratory flow through the tracheostomy tube. Two limiting mechanisms are used to prevent unexpected changes in the airflow channel position after adjustment, ensuring the stability of airflow adjustment and guaranteeing patient safety.

[0033] The airflow regulating mechanism 2 includes a regulating valve 21, a first rotating shaft 22 and a second rotating shaft 23; the first rotating shaft 22 is connected to a first engagement tooth 221 at the end away from the regulating valve 21, and the second rotating shaft 23 is provided with a first engagement tooth 221 that cooperates with the first engagement tooth 221 at the end near the first rotating shaft 22.

[0034] The regulating valve 21 is linked to the second rotating shaft 23 via the first rotating shaft 22, and the size of the airflow passage opening is adjusted by rotating the rotating shaft. The design of the first meshing tooth 221 allows the two rotating shafts to mesh firmly, and when the regulating valve 21 rotates, the two meshing teeth can ensure the accuracy and stability of the rotation.

[0035] The second rotating shaft 23 has a baffle 24 connected to the end away from the first rotating shaft 22.

[0036] Baffle 24, connected to the second rotating shaft 23, is used to adjust the opening and closing state of the airflow channel during the operation of the regulating valve 21. By rotating the second rotating shaft 23, baffle 24 can gradually open or close the airflow channel, thereby controlling the airflow entering the trachea. This design ensures the flexibility and precision of airflow regulation, enabling medical staff to better regulate the airflow balance inside and outside the trachea to meet the respiratory needs of patients at different stages.

[0037] An angle display panel 3 is also provided between the airflow regulating mechanism 2 and the main body of the plug cap 1.

[0038] The angle display panel 3 is used to display the current rotation angle of the regulating valve 21, intuitively reflecting the airflow regulation status. Through the angle display panel 3, medical staff can quickly understand the specific situation of airflow regulation, avoiding over-adjustment or inaccurate operation, thereby improving the ease of use and operational accuracy of the equipment.

[0039] The two limiting mechanisms ensure that the regulating valve 21 remains stable at the set air flow rate, preventing changes in air flow rate due to accidental activation.

[0040] Example 2

[0041] Based on Embodiment 1, Embodiment 2 provides the specific structures of the first limiting mechanism 4 and the second limiting mechanism 5, as shown in the attached figure. Figure 4-9The first engagement tooth 221 is externally provided with a first limiting mechanism 4 that cooperates with it. The first limiting mechanism 4 includes a first annular base 43 and a first cover 44. The first base 43 is sleeved on the outside of the end of the first rotating shaft 22 where the first engagement tooth 221 is located. The inner sidewall of the first base 43 is provided with a plurality of mounting slots. A first spring 42 is installed in each mounting slot. The free end of the first spring 42 is connected to a first trapezoidal block 41. The first trapezoidal block 41 is slidably connected to the sidewall of the mounting slot, so that the first trapezoidal block 41 can slide along the inside and outside of the mounting slot. When the first rotating shaft 22 slides inward, it interacts with the second rotating shaft 22. When shaft 23 is engaged, the first trapezoidal block 41 corresponding to the engagement groove between the first engagement teeth 221 is squeezed and moves in the opposite direction to the center of the first base 43, disengaging from the limiting state. When the regulating valve 21 is pulled out, the first trapezoidal block 41 corresponding to the engagement groove between the first engagement teeth 221 is no longer squeezed by the first engagement teeth 221. Under the action of the first spring 42, it moves towards the center of the first base 43, thereby engaging in the engagement groove between the first engagement teeth 221 and limiting the first rotating shaft 22. This prevents the first rotating shaft 22 from continuing to rotate when it reaches the predetermined angle, causing the angle display dial 3 to show a discrepancy between the actual rotation and the actual rotation. The first cover 44 is on top of the first spring 42 and is connected to the first base 43.

[0042] The first trapezoidal block 41 has an inclined surface at one end near the first rotating shaft 22, and the narrow end of the inclined surface faces the center of the first base 43.

[0043] The second engagement tooth 231 is externally provided with a second limiting mechanism 5 that cooperates with it. The structure of the second limiting mechanism 5 is the same as that of the first limiting mechanism 4, except that the direction of the inclined plane is different. Specifically, the second limiting mechanism 5 includes a ring-shaped second base 53 and a second cover 54. The second base 53 is sleeved on the outside of the end of the second rotating shaft 23 where the second engagement tooth 231 is located. Multiple mounting slots are opened on the inner side wall of the second base 53. A second spring 52 is installed in each mounting slot. The free end of the second spring 52 is connected to a second trapezoidal block 51. The second trapezoidal block 51 is slidably connected to the side wall of the mounting slot, so that the second trapezoidal block 51 can slide along the inside and outside of the mounting slot. The number of the second trapezoidal blocks 51 and the... Corresponding to the second engagement tooth 231, when the first rotating shaft 22 slides outward and disengages from the second rotating shaft 23, the second trapezoidal block 51, corresponding to the engagement groove between the second engagement teeth 231, is not squeezed by the first engagement tooth 221. Under the action of the spring, it moves towards the center of the second base 53, thereby engaging in the engagement groove between the second engagement teeth 231 and limiting the second rotating shaft 23. This prevents the second rotating shaft 23 from continuing to rotate when it reaches the predetermined angle, ensuring that the regulating valve 21 remains stable at the set airflow rate and preventing over-adjustment or instability. The second cover 54 is on top of the second spring 52 and is connected to the second base 53. The inclined surface of the second limiting mechanism 5 faces the opposite direction to the center of the second base 53.

[0044] Specific application examples:

[0045] After a tracheotomy, the patient needs to gradually transition to spontaneous breathing. The specific application method of the tracheotomy cannula plugging cap of this application is as follows:

[0046] Connect the tube cap body 1 to the endotracheal cannula, ensuring a secure connection and good sealing. Adjust the airflow by pressing and rotating the regulating valve 21 according to the patient's breathing needs. At this time, the regulating valve 21 is linked to the first rotating shaft 22 and the second rotating shaft 23, controlling the baffle 24 to gradually open or close the airflow passage. When the appropriate airflow is reached, the first trapezoidal block 41 of the first limiting mechanism 4 engages with the first engagement tooth 221 under the action of the first spring 42, locking the position of the regulating valve 21 and preventing accidental activation that could cause inaccurate readings on the angle display panel 3. The second trapezoidal block 51 of the second limiting mechanism 5 engages with the second engagement tooth 231 under the action of the second spring 52, preventing the second rotating shaft from rotating and preventing accidental changes in airflow adjustment. The angle display panel 3 allows real-time monitoring of the rotation angle of the regulating valve 21, ensuring operational accuracy. To adjust the airflow, press the regulating valve 21 to release the two limiting mechanisms and rotate the regulating valve 21 again to adjust the airflow.
