Embodiment Construction
[0013] The setting structure of the subglottic suction device of the practical artificial airway will be further described below through the method of use. When in use, the negative pressure connecting tube (1) is directly connected to the negative pressure drainage meter (6) and the central negative pressure connection (7), the subglottic drainage tube (2) is directly connected to the subglottic suction end of the patient, and the collection bottle (5 ) is fixed on the patient’s bed by a lanyard. Adjust the negative pressure gauge and turn on the negative pressure. The secretion can be drained into the collection bottle (5) along the subglottic drainage tube (2). When the secretion is thick and needs to be washed, you can Irrigate and aspirate directly through the side tube (3) of the drainage tube.

The invention provides a subglottic sucking device for artificial airway. The subglottic sucking device for artificial airway is a one-use medical consumption material closely related to clinical care and nursing. The device comprises a negative pressure connecting tube, a draining tube and a collecting bottle. The device is characterized in that the collecting bottle is manufactured from transparent plastic and equipped with scales, and the collecting bottle is 500ml in capacity; a plug is arranged an opening of the collecting bottle; the negative pressure connecting tube and the draining tube are inserted through the plug; the other end of the negative pressure connecting tube is connected with a central negative pressure part through a negative pressure draining gauge; the other end of the draining tube is connected to a subglottic sucking end of catheter of artificial airway of a patient; when in operation, subglottic secreta of the patient is drained into the collecting bottle through the draining tube under the negative pressure effect. The device is simple to use, safe, sanitary, difficult to cause cross infection, and convenient to handle.
Description
Technical field: [0001] Disposable consumables for medical treatment and nursing care. Background technique: [0002] Current studies have shown that the establishment of an artificial airway weakens the cough reflex and the ciliary movement of the tracheal mucosa, destroying the defense mechanism of the normal airway, and the pathogenic bacteria in the stomach can retrogradely colonize the oropharynx, and the secretions of these oropharynx The pathogenic bacteria of gastric reflux and gastric reflux often gather above the air bag of the tracheal tube. Studies have reported that the aspiration of the retentate on the air bag of the tracheal intubation or tracheostomy tube is an important cause of ventilator-associated pneumonia. Subhilar retentate significantly reduces the incidence of ventilator-associated pneumonia. In clinical nursing work, with the help of artificial airway with subglottic drainage catheter, subglottic continuous suction, dynamic assessment of the amoun...
