Description

Continuous suction and intermittent lavage device under artificial airway glottis

The technical field is as follows:

the utility model mainly relates to an artificial airway continuously attracts under glottis and is interrupted lavage device, mainly relates to the medical auxiliary instrument field.

Background art:

at present, the establishment of artificial airway for patients with respiratory distress or respiratory failure is an effective respiratory support method, and the establishment of artificial airway is an invasive operation, which maintains effective respiration and simultaneously interferes with the original clearance mechanism of the respiratory tract, such as cough reflex and pharyngeal reflex attenuation, so that the secretion of the upper respiratory tract and the aspiration in the digestive tract are accumulated above the tracheal catheter balloon, and the colonization of bacteria is easily caused. Although a certain pressure exists in the saccule to isolate the lower respiratory tract from the outside, the saccule and the respiratory tract can not be completely attached due to the individuality difference of the respiratory tract and the structural irregularity, and when secretions exist above the saccule, the secretions can easily flow downstream to the lower respiratory tract due to gravity, so that the risk of lung infection is increased. A large number of researches prove that secretion above a subglottic air sac can be effectively cleared by continuously sucking and irrigating a patient with mechanical ventilation under the glottis, the permanent planting of bacteria is reduced, and the probability of lung infection is reduced. Currently, the existing device in clinic cannot complete suction and lavage synchronously, generally, lavage liquid is injected after the negative pressure suction is suspended, then the negative pressure suction is carried out, so that the lavage liquid is retained in an air passage for a period of time, the lavage liquid and secretion are easy to infiltrate, foam or sponge dressing is also used for preventing infiltration aiming at the problem, but the dressing is easy to cause bacterial permanent planting, and the residues on the dressing are difficult to remove by intermittent lavage; and part of the research is that a plurality of lavage and suction tubes cause the increase of airway load; meanwhile, the nurse has low lavage compliance to the patient due to the large number of operating steps. For the negative pressure suction tube, mostly for the haplopore suction, this has the problem in two aspects, and on the one hand the haplopore suction its local negative pressure is big, causes local mucous membrane damage to bleed easily, and on the other hand, can't normally attract after the haplopore takes place to block up the pipe, influences the suction effect. Aiming at the sample retention of airway secretion, the existing method is easy to cause sample pollution and pollution in an aspiration tube.

The invention content is as follows:

the utility model aims to simultaneously perform continuous suction and intermittent lavage, thereby shortening the retention time of lavage fluid; the phenomenon that a plurality of suction tubes and lavage tubes increase the load of the airway is avoided; the porous negative pressure suction avoids the occurrence of single-hole blockage and local mucosal injury; the lavage tube is slightly shorter than the subglottic suction tube, so that the lavage tube is beneficial to washing airway secretions from the lower part of the pharynx to the upper part of the saccule; due to the design of the specimen box, the specimen is prevented from being polluted when being left and taken, and the aim of simple operation is fulfilled; the syringe is connected through the tee joint for lavage, so that the operation is simple and convenient, and the lavage compliance of nurses is improved; the transparent design of the body of the liquid collecting bottle and the design of the scales are favorable for observing the color, the character and the amount of the lavage liquid, and the design of the stainless steel external fixing frame is convenient for the liquid collecting bottle to be vertically fixed beside a bed.
