Fluid input module for multi-lumen catheters
First Claim
1. Apparatus for use with a tracheal ventilation tube, a pressurized fluid source, and a suction source separate from the pressurized fluid source, the apparatus comprising:
- a cleaning catheter, which (a) is insertable into the ventilation tube, (b) is shaped so as to define one or more distal suction orifices, and (c) which comprises;
an elongate, flexible, tubular main body; and
an inflatable element, which is mounted to the main body at a location within 3 cm of at least one of the one or more distal suction orifices; and
an input module, which is coupled to the cleaning catheter, and comprises a flow regulator, which;
(a) is shaped so as to define (i) a suction port coupleable in fluid communication with the suction source, and (ii) a fluid port, which is separate from the suction port, and(b) is configured to assume at least first and second activation states, such that;
the flow regulator, when in the first activation state, effects fluid communication between the suction source and an interior of the inflatable element, thereby deflating the inflatable element, andthe flow regulator, when in the second activation state, effects fluid communication between the suction source and the distal suction orifices, and does not effect the fluid communication between the suction source and the interior of the inflatable element,wherein the interior of the inflatable element is selectably coupleable in fluid communication with the pressurized fluid source via the fluid port, andwherein the fluid port (a) is not in fluid communication with the suction port in the first activation state, and (b) is not in fluid communication with the suction port in the second activation state.

Abstract
A cleaning catheter (200) includes fluid-delivery and suction lumens (520, 530). A flow regulator (700) defines suction and fluid ports (830, 827). A mechanical user control element (320) is configured to mechanically and non-electrically set activation states of the flow regulator (700), and transition between first and third configurations via a second configuration. When the control element (320) is in the first configuration, the flow regulator (700) blocks fluid communication (a) between the suction port (830) and the suction lumen (530) and (b) between the fluid port (827) and the fluid-delivery lumen (520). When the control element (320) is in the second configuration, the flow regulator effects fluid communication between the suction port (830) and the suction lumen (530), and blocks fluid communication between the fluid port (827) and the fluid-delivery lumen (520). When the control element (320) is in the third configuration, the flow regulator (700) effects fluid communication (a) between the suction port (830) and the suction lumen (530) and (b) between the fluid port (827) and the fluid-delivery lumen (520).
