Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a reinforcement component for a ventilator pipeline and an endotracheal cannula. Background Art

[0002] Most of the ways to connect the ventilator pipeline and the endotracheal tube are to connect them by direct insertion, which mainly relies on the friction of the material. However, if it is affected by external forces, it will still be disconnected. Therefore, it is necessary to use a reinforcement component to reinforce the connection between the ventilator pipeline and the endotracheal tube to ensure that the connection can transport oxygen normally.

[0003] Most existing fixing devices are reinforced by connecting with two threaded heads. This method is not convenient for medical staff to replace the endotracheal tube. At the same time, the small structure of the connection is not convenient for the threaded connection operation, which will bring inconvenience to medical staff. Utility Model Content

[0020] See also Figure 1 and Figure 4 The utility model provides a technical solution: it includes an endotracheal tube body 1 and a locking assembly 8, one end of the endotracheal tube body 1 is connected to a endotracheal connector 2, a first sealing ring 3 is provided on the outside of the endotracheal connector 2, and a protective outer ring 7 is provided on the outside of the first sealing ring 3, the locking assembly 8 is located on the upper and lower sides of the protective outer ring 7, and the locking assembly 8 includes a fixing frame 801, an elastic rod 802, a plug 803 and a connecting rod 804, and the side of the fixing frame 801 close to the protective outer ring 7 is connected to the elastic rod 802, the side of the elastic rod 802 away from the fixing frame 801 is connected to the plug 803, and the side of the plug 803 is connected to the connecting rod 804, and the side of the protective outer ring 7 away from the upper end of the locking assembly 8 is connected to the ventilator pipeline body 9.

[0021] By means of the elastic telescopic structure formed between the elastic rod 802 and the fixing frame 801, the plug 803 is extended, thereby causing the plug 803 to clamp the first sealing ring 3, thereby achieving auxiliary fixation of the connection between the endotracheal tube body 1 and the ventilator pipe body 9. At the same time, the movement of the plug 803 can be controlled by pressing the connecting rod 804, thereby facilitating the disassembly of the endotracheal tube body 1 by medical personnel.

[0022] like Figure 2 and Figure 3 As shown, a pipe connector 4 is provided on the side of the tracheal connector 2 away from the tracheal tube body 1 , and a docking assembly 5 is provided on the outside of the pipe connector 4 .

[0023] The docking assembly 5 facilitates sealing the connection between the trachea connector 2 and the pipe connector 4 to prevent air leakage at the equipment connection.

[0024] like Figure 2 As shown, the docking assembly 5 includes a rotating ring 501, a spring 502 and a guide rod 503, and the spring 502 is connected to one side of the rotating ring 501, and the guide rod 503 passes through the inside of the spring 502. The docking assembly 5 also includes a second sealing ring 504 and an auxiliary docking block 505, and the second sealing ring 504 is connected to the side of the spring 502 away from the rotating ring 501, and the auxiliary docking block 505 is embedded in the inside of the second sealing ring 504.

[0025] Relying on the elastic telescopic structure formed between the second sealing ring 504 and the rotating ring 501 through the guide rod 503 and the spring 502, the second sealing ring 504 is facilitated to dock with the first sealing ring 3, thereby increasing the stability of the equipment. At the same time, the rotating ring 501 can rotate on the pipe connector 4, thereby facilitating the docking of the auxiliary docking block 505 with the groove on the pipe connector 4, thereby increasing the docking stability of the equipment.

[0026] like Figure 2As shown, the rotating ring 501 is rotationally connected to the pipe connector 4, and the second sealing ring 504 is slidingly connected to the pipe connector 4. The other side of the rotating ring 501 is connected to the limiting block 6, and the limiting block 6 is fixed to the pipe connector 4.

[0027] Working principle: First, when in use, the trachea connector 2 is inserted into the protective outer ring 7. The plug 803 is connected to the protective outer ring 7 through the elastic telescopic structure between the elastic rod 802 and the fixing frame 801. When the trachea connector 2 is inserted, the first sealing ring 3 can push the plug 803 open, so that the plug 803 is stuck on one side of the first sealing ring 3, limiting the position of the first sealing ring 3, thereby realizing the connection between the trachea connector 2 and the pipe connector 4. The second sealing ring 504 is connected to the first sealing ring 3 through the elastic telescopic structure between the guide rod 503 and the spring 502 and the rotating ring 501, which facilitates the docking of the second sealing ring 504 with the first sealing ring 3. This facilitates the connection of the equipment. At the same time, the rotating structure between the rotating ring 501 and the docking assembly 5 facilitates the rotating ring 501 to drive the second sealing ring 504 to rotate, thereby facilitating the auxiliary docking block 505 to be embedded in the groove of the first sealing ring 3, thereby achieving a tight connection between the first sealing ring 3 and the second sealing ring 504, and achieving the connection stability of the tracheal connector 2 and the pipe connector 4, thereby facilitating a stable connection between the tracheal tube body 1 and the ventilator pipe body 9. The rotating ring 501 is limited by the limit block 6 to prevent the rotating ring 501 from moving and affecting the docking of the second sealing ring 504 and the first sealing ring 3.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
