Benefits of technology
The present invention provides a multi-lumen catheter for cleaning the inner surface of a tracheal ventilation tube. It enables simultaneous inflation and suctioning in a closed suction system without the need for detachment from the ventilation air supply. The inflatable element is designed to be deflated when its internal pressure is at a negative pressure of up to -25 cm H2O to prevent accumulation of biofilm and dragging it up the ventilation circuit. The input module prevents accidental inflation without suction and maintains the inflatable element at negative pressure during transition of the mechanical suction-control button.
Problems solved by technology
A problematic aspect of the use of suction catheters is the presence of bacterial biofilm within the ETT lumen through which the suction catheter passes.
Consequently, as the suction catheter is inserted, there is high risk of it carrying bacterial biofilm from the ETT lumen deeper into the bronchial tree where the suction catheter reaches, and thereby increasing the risk of lung infection.
Moreover, buildup of substantial biofilm thickness reduces the effective free lumen of the ETT for air passage.

Embodiment Construction
[0131]The figures are schematic illustrations of several configurations of a closed suction cleaning system 100, in accordance with respective applications of the present invention. Cleaning system 100 is typically configured for use with a tracheal ventilation tube, a ventilator, and a suction source. For some applications, cleaning system 100 comprises one or more of the tracheal ventilation tube, the ventilator, and / or the suction source, in any combination. Although these elements are not illustrated in the figures, they can be seen in FIGS. 1A-D of U.S. Pat. No. 8,999,074 to Zachar et al., which is incorporated herein by reference. Cleaning system 100 may be implemented as shown in FIGS. 1A-D of the '074 patent, mutatis mutandis, except that cleaning system 100 typically does not comprise the pressurized fluid source 602 shown in these figures.

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 in 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 communication with the suction source.
Description
CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to U.S. provisional patent application No. 62 / 528,673, filed Jul. 5, 2017, the disclosure of which is incorporated by reference in its entirety.FIELD OF THE APPLICATION[0002]The present invention relates generally to medical suction catheter devices, and specifically to catheter devices for aspiration of tracheobronchial secretions and / or cleaning of tracheal ventilation tubes.BACKGROUND OF THE APPLICATION[0003]Suction catheters are commonly used to aspirate tracheobronchial fluids in patients ventilated with endotracheal tube (ETT) and tracheostomy tube devices. A problematic aspect of the use of suction catheters is the presence of bacterial biofilm within the ETT lumen through which the suction catheter passes. Consequently, as the suction catheter is inserted, there is high risk of it carrying bacterial biofilm from the ETT lumen deeper into the bronchial tree where the suction catheter reaches, and the...
