Adjustable multifunctional subglottic absorption and collection device

Technical Field

The invention relates to the technical field of medical supplies, in particular to an adjustable multifunctional subglottic absorption and collection device.

Background

The respiratory tract of a patient who establishes the artificial airway is directly opened, physiological defense functions of preventing aspiration and clearing airway secretions and the like of the respiratory tract under normal conditions are lost, oropharyngeal secretions, gastrointestinal reflux and the like are easy to gather between a glottis and the artificial airway air bag, and can leak downwards to the lower respiratory tract along the periphery of the air bag to cause lung infection. Timely clearing of the residues deposited under the glottis is an effective measure for ensuring that the airway of a patient is smooth, reducing aspiration and ventilator-associated pneumonia, reducing hospitalization time, reducing cost and ensuring the safety of the patient. The methods commonly used in the clinic are continuous and intermittent subglottic aspiration.

Currently, the clinic generally uses a syringe to manually suck to perform the subglottic suction or uses a sputum suction connecting tube to perform the continuous or subglottic suction. Manual suction can not accurate control attracts the negative pressure, attracts at every turn to need to change the syringe, needs repeated disconnection, disinfection, connection syringe simultaneously, causes the increase of patient's consumptive material cost and nursing cost, and non-closed operation increases the risk of pollution simultaneously, further increases patient's respiratory infection risk. The sputum suction connecting pipe is used for continuous or intermittent subglottic suction, so that the quantity of subglottic secretions cannot be accurately collected and observed, and the continuous and intermittent subglottic suction can not be switched quickly and without disconnection according to the requirements of the patient. If the subglottic retentate sample needs to be collected, the continuous suction device needs to be disconnected for additional collection operation.
