Device capable of simultaneously nursing trachea and trachea cannula

Abstract

The invention relates to a device capable of simultaneously sucking secretion in a trachea and a trachea cannula and rinsing and cleaning the inner wall of the trachea cannula, which is characterized in that: the pipe wall of a suction catheter (1) is provided with at least three small pipes (2) which are parallel and equidistant; one end of each small pipe is opened on the pipe wall (3) of the suction catheter and has a distance of between 20 and 50 mm from a remote opening of the suction catheter, while the other ends of the small pipes are integrated into a pipeline (4) at the near end of the suction catheter, and the opening of the pipeline (4) can be connected with an injector; and the surface of the suction catheter is provided with a granulated scale (5). By rinsing and cleaning the inner wall of the trachea cannula at fixed positions, colonized bacteria and sputum crusts are prevented from appearing on the inner wall of the trachea cannula, the occurrence of ventilator associated pneumonia is reduced and the curative effect of mechanical ventilation is improved.

Description

Technical field: [0001] This patent relates to a device that can simultaneously suck the secretions in the airway and the endotracheal tube, and flush and clean the inner wall of the endotracheal tube. Background technique: [0002] For respiratory failure caused by various etiologies, endotracheal intubation and mechanical ventilation are required to maintain the patient's vital signs and provide sufficient time for the treatment of the etiology. There are secretions in the airway of mechanically ventilated patients. These secretions need to be sucked through the sputum suction tube in time. Otherwise, these secretions may adhere to the inner wall of the endotracheal tube due to the patient's cough, which not only causes bacterial colonization, Moreover, the formation of sputum scab can lead to ventilator-associated pneumonia, which will finally affect the effect of mechanical ventilation and the curative effect of patients. The nursing method of endotracheal intubation at...

AI Technical Summary

Problems solved by technology

Since the inner diameter of the tracheal intubation tube is circular, and its length reaches 250mm and has a certain arc, the instilled saline flows from the high position to the low position; at the same time, the sputum suction tube is a blind suction, and the suction adhesion cannot be controlled arbitrarily. Sputum on the inner wall of the trachea, so current nursing methods for endotracheal tubes cannot effectively clean the inner wall of the endotracheal tube
