Rolling brush type sputum scab cleaning device for artificial airway

Abstract

The invention relates to a rolling brush type sputum scab cleaning device for an artificial airway. The rolling brush type sputum scab cleaning device comprises a ventilating pipe, a blocking air bag,a sputum sucking rolling brush and a sputum sucking tube, wherein the sputum sucking tube is of a tube body with an annular cavity composed of an inner tube and an outer tube, the sputum sucking rolling brush comprises a disc body, a sputum storage chamber is arranged inside the disc body, multiple groups of brush hair are uniformly distributed on the circumferential face of the disc body, and one sputum sucker is arranged between every two adjacent groups of brush hair. During sputum sucking, on one hand, through matching between the blocking air bag and the ventilating pipe, a negative-pressure environment can be completely isolated from the interior of a body of a sufferer, and the condition that hypoxemia occurs due to the fact that gas volume of peripheral lung tissue of the suffereris reduced due to the fact that a negative-pressure sucking force sucks gas during sputum sucking is avoided; and on the other hand, the sputum suckers can rotate, sputum adhered to the wall of the artificial airway can be scraped off and sucked off successfully through rotating operation, and thus, the effect of deep cleaning is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a rolling brush type artificial airway sputum scab cleaner. Background technique [0002] The artificial airway is a gas channel established by inserting a catheter directly into the trachea or through the upper respiratory tract to provide conditions for effective drainage, patency and mechanical ventilation of the airway. The most commonly used artificial airways are endotracheal intubation and tracheostomy tubes. Patients with upper airway obstruction, retention of airway secretions, and patients requiring mechanical ventilation all need to establish an artificial airway. [0003] The establishment of the worker's airway can ensure that the patient has sufficient oxygen supply and reduce airway obstruction. After the artificial airway is established, it should be properly managed, including the fixation of the artificial airway, the humidification of the artificial ai...

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
