Sputum suction device for deeply cleaning artificial airway

Abstract

The invention provides a sputum suction device for deeply cleaning an artificial airway. The sputum suction device comprises a ventilation pipe, a blocking air bag, a sputum suction head and a sputumsuction pipe. The sputum suction pipe is a pipe body which is composed of an inner pipe and an outer pipe and provided with an annular cavity, the sputum suction head is in a gear-like shape, a sputumstorage cavity is formed in the sputum suction head, and a first through hole and a second through hole are formed in the two sides of the sputum suction head respectively. The sputum suction deviceis used for deeply cleaning the artificial airway; in the sputum suction process, on one hand, through the cooperation of the blocking air bag and the ventilation pipe, the negative pressure environment is completely isolated from the body of a patient, and the situation that the negative pressure suction force in the sputum suction process sucks out gas, the gas amount of the peripheral lung tissue of the patient is reduced, and the hypoxemia occurs is avoided; and on the other hand, the sputum suction head can rotate, sputum adhering to the pipe wall of the artificial airway can be scraped off and smoothly sucked away through rotation operation, and the deep cleaning effect is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a sputum suction device for deeply cleaning an artificial airway. Background technique [0002] Artificial airway is a means to make the airway unobstructed by artificial means when the airway ventilation is obstructed due to various diseases. It refers to the establishment of an effective link between the physiological airway and air or other air sources to ensure the unobstructed airway. The purpose of establishing an artificial airway is mainly to relieve airway obstruction, remove respiratory secretions, and prevent aspiration. [0003] Common types of artificial airways include face masks, nasal masks, oropharyngeal airways, nasopharyngeal airways, laryngeal masks, tracheal intubations, tracheotomy, combined tracheoesophageal catheters, etc. The establishment of artificial airway provides the basis for emergency patient rescue, respiratory support for critically ill...

AI Technical Summary

Problems solved by technology

When suctioning airway secretions, two problems are often faced. One is that a large amount of sticky sputum in the airway is attached to the inner wall of the tube, and it is difficult to completely peel off the sticky sputum from the tube wall only by suction. During the period of sputum, if a strong negative pressure is used, in addition to suctioning sputum, gas will also be sucked out, resulting in a decrease in the amount of gas reaching the patient's peripheral lung tissue, and hypoxemia is prone to occur; Long sputum time will affect the patient's ventilation effect and lead to hypoxemia
