[0002] An artificial airway refers to a gas exchange channel established by inserting a tracheal catheter through the patient's mouth or nasal cavity or performing a tracheotomy, and has currently become an important treatment means for patients. During normal breathing, about 200 ml of water is lost from the airway per day, while the daily water loss from the airway of a tracheotomy patient reaches more than 800 ml / d. Due to tracheotomy, the functions of the upper respiratory tract to filter, humidify, and warm the inhaled gas disappear, resulting in increased evaporation of respiratory tract moisture, weakened or disappeared ciliary movement of airway mucosa, and difficulty for patients to cough up or aspirate sputum. In severe cases, sputum crusts may form, leading to the occurrence of dyspnea in patients. Currently, there are continuous airway humidification and intermittent humidification devices in clinical practice, but the existing humidifying and liquid adding devices are large in size and complex in structure, with poor convenience in clinical use.

[0017] Embodiment: A humidifying and liquid adding device for a tracheotomy cannula, the structure is as follows Figure 1-2 shown, including a tracheotomy cannula body 1 and a syringe 10. One end of the tracheotomy cannula body 1 is provided with a connected adapter 2, and the lower end of the adapter 2 is provided with a connected trachea 3. As shown in the appendix Figure 1 shown, the adapter 2 is in a T shape and is used to connect the tracheotomy cannula body 1 and the trachea 3, which can ensure the smooth flow of oxygen. The adapter 2 includes a first sleeve 17. There is a sleeve opening 18 on the tracheotomy cannula body 1, and the left end of the first sleeve 17 is sleeved on the sleeve opening 18. An exhaust port 6 is provided on the right side of the first sleeve 17. A sleeve ring 7 is sleeved in the middle of the first sleeve 17, and a second sleeve 8 is provided at the lower end of the sleeve ring 7. The second sleeve 8 is perpendicular to the first sleeve 17. One end of the second sleeve 8 is connected to the first sleeve 17. The other end of the second sleeve 8 is connected to the trachea 3. One end of the trachea 3 is provided with a connected humidifying cup 4. The humidifying cup 4 contains a humidifying liquid, and normal saline or other suitable liquids are injected into it through the syringe 10 to keep the oxygen moist. The humidifying cup 4 includes a cup body 11 and a cup cover 12. The cup body 11 and the cup cover 12 are connected by threads. An air tube connection port 15 is provided at the upper end of the cup cover 12, and the trachea 3 is connected to the air tube connection port 15. A fine mesh 16 is provided at the place where the upper end of the cup body 11 communicates with the air tube connection port 15. The fine mesh 16 can adsorb and disperse the large particle droplets blown out by the oxygen. Preferably, as shown in the appendix Figure 2 shown, an oxygen cone 5 is provided at the bottom of the inner cavity of the humidifying cup 4. The oxygen cone 5 is made of high-strength medical glass fiber composite resin and has a certain conical structure. The oxygen cone 5 can play a certain role in lifting the liquid level in the humidifying cup 4. A number of oxygen holes 19 are provided on the side of the oxygen cone 5. A liquid inlet 13 is provided on one side of the cup body 11, and the syringe 10 is connected to the liquid inlet 13. The syringe 10 and the humidifying cup 4 are connected by a thin tube for transporting the humidifying liquid. The liquid medicine can also be directly transported into the humidifying cup through the thin tube to the liquid inlet for atomization inhalation. There is no need to connect an atomizer after removing this device, and the operation is convenient and the practicability is strong. An air inlet 14 is provided at the bottom of the cup body 11, and an air inlet tube 9 is connected to the air inlet 14.

This device is provided with an oxygen cone 5 and a number of oxygen holes 19 in the humidifying cup 4. Due to the liquid level lifting effect of the oxygen cone 5, the humidifying liquid in the humidifying cup 4 fully contacts the oxygen holes 19, which is beneficial to the humidification of oxygen. This device takes into account the convenience of clinical use. For example, by injecting humidifying liquid into the humidifying cup 4 through the syringe 10 and sleeving the adapter 2 on the tracheotomy cannula, etc., the operation process of the device is simplified and the labor intensity of medical staff is reduced. This device ensures the stability and safety of the device during use through reasonable structural and material selection.

[0018] Working process

[0019] During use, it is necessary to first assemble the various components of the device, place the humidifying cup 4 in a suitable position, and then use a syringe 10 to transport the humidifying liquid into the humidifying cup 4 through the liquid inlet 13. After the humidifying liquid drips into the humidifying cup 4, due to the presence of the oxygen cone 5 and the oxygen holes 19, the humidifying liquid in the humidifying cup 4 can fully contact the oxygen holes 19. At this time, when the oxygen in the air inlet pipe 9 flows through the oxygen cone 5, it can gush out from the oxygen holes 19 and carry away part of the humidifying liquid, thus achieving the humidifying effect. Then the humidified oxygen passes through the trachea 3, the adapter 2 and the tracheotomy cannula body 1 in sequence and is inhaled into the airway, thus playing a role in continuous humidification.

[0020] In summary, the utility model can realize the humidifying function of the artificial airway, and has the advantages of simple structure and strong convenience.
