An endotracheal tube (1) comprises a tubular body (2) having a form of a flexible curved transparent tube with open proximal (3) and distal (4) ends, a connector (7) mounted on the proximal end of the tube and served for attaching a tube cavity to a ventilation device, an inflatable cuff (9) having a cavity, said inflatable cuff fixed hermetically around the distal end of the curved tube and configured to be inflated to seal the cuff against a wall of a patient's trachea and to hold the distal end of the endotracheal tube in the desired position in a patient's larynx, a longitudinal air supply channel (10) in the wall of the tubular body, said channel being in communication with the cavity of the inflatable cuff, a sealed balloon (12) having elastic walls and configured to maintain and monitor pressure in the cuff cavity, the sealed balloon connected to an air supply port, and connected via a catheter (13) to the longitudinal air supply channel to supply an air into the cuff cavity, and a mark (14) made on the surface of the tube from the side of the proximal end at a distance of 2.5-3 cm from the inflatable cuff, wherein the inflatable cuff comprises two layers (15,16), wherein an outer layer (15) of the inflatable cuff is made of a porous biocompatible polymer material and serves as a depot for input and hold the drug in the pores of the polymer material and remove the drug from the pores of the zone of contacting of the cuff with the trachea when the cuff is inflated providing infusion of the drug into the tracheal mucosa.

A cleaning device, system and method for use with an ETT or tracheostomy ventilation tube 60, a ventilator machine 900, a source(s) 602 of fluid (for example, pressurized or unpressurized) and a source(s) of suctioning 603 is disclosed. In some embodiments, the cleaning device is useful for cleaning an inner surface of the ventilation tube 60 and/or for preventing or hindering the accumulation of biofilm thereon. In some embodiments, it is possible to clean biofilm or any other material on the inner surface 201 by delivering fluid into an interior of the ventilation tube, wiping the tube interior with a width-expanded wiping element (e.g. an inflated balloon) by longitudinal motion of the wiping element, and suctioning material out of the ventilation tube.

A device for delivering a substance to an airway of a patient may include a laryngeal mask airway device, at least one substance delivery reservoir coupled with the laryngeal mask airway device for delivering the substance to the airway of the patient, and at least one conduit coupled with the laryngeal mask airway. The at least one conduit may have a proximal end configured to couple with a source of the substance residing outside the patient and a distal end in fluid communication with the at least one substance delivery reservoir.

Many pneumonia diseases and lung malfunctions can be quickly repaired using an improved lung lavage technique where the patient is rotated in specific 3D orientations to increase the efficiency of the lavage procedure. The process involves filling and emptying the lungs with fluid and rotating the patient makes this process natural and effective. Supplementary, a hydro-pneumatic system facilitates the operations with the patient sustained in various positions such as being immersed in water and having various control mechanisms such as variable pressures, temperatures, and performing assisted breathing. Additionally, immersed devices are implanted that shake-up of alveolar wall and other devices perform ultrasound imaging with a 0.1 mm resolution, a resolution in competition with stereoscopic X-ray. The bio-medical data acquisition system allows physicians to completely assess patient status in real time and guide the treatment to ensure optimum patient care, under quality assurance procedures.

Tracheal tube systems may include first and second tubes and an inflatable balloon. The first tube may be flexible and hollow and have first and second open ends. The inflatable balloon may be affixed to and circumferentially surround a portion of the first tube. The inflatable balloon may include an indentation sized and positioned to accommodate a portion of a second tube positioned therein, when the inflatable balloon is inflated. The second tube may be hollow and have a multiplicity of holes along a sidewall not in contact with the balloon. The second tube may be configured to be coupled to a suction device that creates a negative pressure in the second tube. When the tracheal tube system is inserted in a patient's trachea, the negative pressure in the second tube may act to remove, or suction out, fluids and other matter from the trachea.

A method of sealing a trachea is provided that includes inserting a tracheal tube having an inflatable cuff made of a compliant material into a trachea. The method includes inflating the inflatable cuff with a fluid to a first pressure that exceeds a second pressure necessary to create a seal between the inflatable cuff and the tracheal wall. The method includes deflating the inflatable cuff by releasing a first pressure to allow the fluid to flow out of the inflatable cuff without applying vacuum pressure to the fluid while evaluating a rate of change of pressure of the fluid in the inflatable cuff. The method includes identifying a variance in the rate of change of pressure corresponding to a third pressure at which the inflatable cuff separates from the tracheal wall, determining the second pressure by analyzing the third pressure, and reinflating the inflatable cuff to the second pressure.
