Description

Technical Field

[0001] The utility model relates to the field of artificial airways, in particular to an atomizer connector suitable for patients with artificial airways. Background Art

[0002] Artificial airway, including endotracheal intubation and tracheotomy, plays an extremely important role in the treatment of critically ill patients. Artificial airway can ensure smooth upper respiratory tract, facilitate the removal of airway secretions, and implement effective ventilation support. It is an indispensable emergency medical device for rescuing respiratory failure, cardiac and respiratory arrest, and general anesthesia surgery. It is an important medical device for effective respiratory management of critically ill patients.

[0003] In some cases, an artificial airway needs to be used in conjunction with a nebulizer for treatment. In the prior art, a mask is usually connected to the nebulizer and then directly buckled onto the position of the patient's artificial airway. The mask seals the space around the artificial airway. This connection method cannot achieve a tight connection. The liquid medicine sprayed by the nebulizer after atomization is easy to flow out from the gap between the mask and the patient, causing a waste of liquid medicine. In addition, because the mask is directly buckled onto the patient, once the patient moves, the mask is easy to shift or even fall off, and the effectiveness of the nebulizer is greatly reduced. Utility Model Content

[0004] The main purpose of the utility model is to overcome the shortcomings of the prior art and provide a nebulizer connector suitable for patients with artificial airways, which connects the drug inlet end and the drug outlet end of the drainage tube to the nebulizer and the artificial airway respectively through a sleeve tube and a connecting tube, thereby ensuring a tight connection between the nebulizer and the artificial airway, avoiding waste of liquid medicine, and having a stable connection and not easy to fall off.
