Embodiment Construction

[0132] The Figure is a schematic illustration of several configurations of an enclosed extraction cleaning system 100 according to various applications of the invention. Cleaning system 100 is generally configured for use with a tracheal airway, ventilator, and suction source. For some applications, cleaning system 100 includes any combination of one or more of a tracheal airway, a ventilator, and / or a suction source. Although these elements are not shown in the figure, reference can be made to the U.S. Patent No. 8,999,074 of Zachar et al. figure 1 A to figure 1 D, this patent is incorporated herein by reference. The cleaning system 100 can be as described in the patent US 8,999,074 figure 1 A to figure 1 Shown mutatis mutandis in D, with the exception that cleaning system 100 generally does not include pressurized fluid source 602 as shown.

[0133] As used in this application, including the claims, "tracheal airway" includes an endotracheal tube (ETT) or a tracheos...

Abstract

A multi-lumen catheter for cleaning an inner surface of a tracheal ventilation tube is provided, which enables single-handed simultaneous activation of inflation of an inflatable element and suctioning in a closed suction system for use with the tracheal ventilation tube. The closed suction system allows catheters to be used repeatedly without being detached from the tube system including the ventilation air supply. The cleaning catheter is insertable into the tracheal ventilation tube, and is shaped so as to define one or more distal suction orifices. The cleaning catheter comprises an elongate, flexible, tubular catheter main body, and an inflatable element, which is mounted to the catheter main body. An input module is coupled to the cleaning catheter, and comprises an inflation module,which comprises an inflation chamber separate from a suction source. The input module also comprises a flow regulator, which is shaped so as to define a suction port coupleable in fluid communicationwith the suction source.

Description

[0001] priority document [0002] This application claims priority to U.S. Provisional Patent Application No. US 62 / 528,673, filed July 5, 2017, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates generally to medical suction catheter devices and in particular to catheter devices for aspirating tracheobronchial secretions and / or cleaning tracheal airways. Background technique [0004] Suction catheters are commonly used to aspirate tracheobronchial fluid in patients ventilated by endotracheal tube (ETT) and tracheostomy tube devices. One problematic aspect of using a suction catheter is the presence of bacterial biofilms within the lumen of the ETT through which the suction catheter passes. Therefore, with insertion of the suction catheter, there is a high risk of introducing bacterial biofilm from the ETT lumen deeper into the bronchial tree reached by the suction catheter, thereby increasing ...
