Embodiment Construction

[0045] With reference to the accompanying drawings, numeral 1 hereinafter shows a device for controlling the pressure in a tracheal cuff according to the invention.

[0046] As already mentioned, this device 1 is connectable (or connected / integrated) to a positive pressure ventilator 100 for the artificial ventilation of an intubated patient "P".

[0047] Thus, the device 1 comprises an endotracheal tube 2 inserted into the airway of a patient "P".

[0048] Thus, the conduit 2 defines a lumen defined by a side wall 2c and extends between a first end 2a, which in use is connected to the exterior of the ventilator 100, and a second free end 2b, the second free end 2b. The free end 2b is placed in the "distal" position in use.

[0049] The conduit 2 is preferably made of PVC or the like.

[0050] Catheter 2 has an associated inflatable cuff 3 .

[0051] The inflatable cuff 3 is a sealing element configured to fit the internal dimensions of the trachea of ​​the patient "P" in ord...

Abstract

A method of managing secretions of an intubated patient through an endotracheal tube (2) associated externally to an inflatable cuff (3), the method comprising: inflating the inflatable cuff (3) to place the patient (P) The bronchopulmonary region of the trachea is isolated from the external environment; a series of overpressures (P1, P2) are generated inside the endotracheal tube (2) to induce breathing in the patient; and during the generation of one of the overpressures (P1, P2), The inflatable cuff (3) is deflated in order to allow secretions (S) produced by the patient (P) to drain externally along the trachea.

Description

technical field [0001] The present invention relates to a device for controlling the pressure in a tracheal cuff, a positive pressure ventilator for artificial ventilation of an intubated patient and a method of managing secretions in an intubated patient. [0002] The invention finds particular application in the production of medical devices, in particular in the realization of devices for forced ventilation. [0003] More specifically, the invention is used in patients fitted with a respiratory prosthesis and / or artificially ventilated patients. Background technique [0004] Clearance of secretions from the airways is notoriously difficult in artificially ventilated patients (especially those undergoing intensive therapy) because the presence of an endotracheal tube and relatively tight cuff prevents what is commonly known as "mucociliary clearance." , the natural mechanism that allows secretions to be expelled automatically through their ascending action along the trach...
