The present invention discloses an end-expiratory CO.sub.2 guided tracheal intubation apparatus. The apparatus comprises: an intubation tube, an end-expiratory CO.sub.2 catheter, a suction tube, an airbag and an inflatable air tube, wherein the end-expiratory CO.sub.2 catheter partially penetrates the sidewall of the intubation tube, one end of the end-expiratory CO.sub.2 catheter extends beyond an end of the intubation tube, and the other end is connected to an end-expiratory CO.sub.2 sensor, the suction tube partially penetrates a sidewall of the intubation tube, one end of the liquid suction tube extends beyond an end of the intubation tube, the other end is connected to an air pump, the airbag sleeves the outer wall of the intubation tube, the inflatable air tube partially penetrates the sidewall of the intubation tube, one end thereof is connected to the airbag, and the other end is connected to the air supply device.

Endotracheal devices and methods of using endotracheal devices are provided. The devices include a first elongated conduit having an internal dimension, a second elongated conduit having an external dimension less than the internal dimension of the first conduit, and a manipulation rod operatively mounted to the second conduit, where the manipulation rod allows an operator to move the second conduit within the first conduit. The manipulation rod may be used translate and/or rotate the second conduit within the first conduit. The first and second elongated conduits may be provided with inflatable cuffs to minimize the passage of fluids. Though aspects of the invention may be uniquely adapted for insertion through the trachea and into a bronchus, aspects of the invention may be used for other bodily passages.

The invention relates to a positioning sputum suction laryngeal mask. The positioning sputum suction laryngeal mask comprises a mask body and a mask body tube, wherein the mask body comprises a mask body bottom plate and a mask main body arranged on the mask body bottom plate, a central region in the mask main body is provided with a mask body cavity communicated with the mask body tube, a stomach decompression tube corresponding to the stomach mouth is arranged on the back side of the mask body bottom plate, and the stomach decompression tube is isolated from the mask body cavity through the mask body bottom plate. The positioning sputum suction laryngeal mask also comprises a connection suction mechanism capable of realizing negative pressure suction in a gas supply process. The connection suction mechanism comprises a suction connecting tube which is arranged in the mask body bottom plate, and the end, located in the mask body bottom plate, of the suction connecting tube is communicated with the stomach decompression tube. The positioning sputum suction laryngeal mask can be effectively positioned, has lower complexity and usage costs, can ensure the ventilation and sealing effect without air inflation in use, can realize suction of secretions in a ventilation process, can avoid airway blockage caused by epiglottis, and can improve the stability and reliability in use.

An irrigating intraluminal suction inner cannula system for a tracheostomy tube may be a suction-powered system that may be used for suction alone or a combination of rinse and intraluminal suction for tracheostomy tubes in place of conventional catheter-based intraluminal suction. An inner cannula includes chambers, or regions, and holes that facilitate intraluminal suction and cleaning at multiple locations within the tracheostomy tube. It may be applied/actuated by a patient, healthcare worker, caretaker, or via an electronic system either on-demand or on regular or triggered intervals, in either inpatient/hospital or outpatient/ambulatory care setting.

A pulmonary secretion clearing airway structure and related airway management system is disclosed that has a double lumen portion which each lumen of the double lumen portion operably secured to an airway management system so that inspiratory fluid (air/oxygen mixtures, with or without added water vapor) is delivered to the distal end of the ventilation catheter through one of the two lumens and expired inspiratory fluid, pulmonary secretions, and pulmonary fluids are removed from the patient through the other lumen. The expiratory fluid pathway preferably includes a secretion collection system for removing the pulmonary secretions and the like from the pathway, thereby improving operation and safety of the system. The airway structure can be a ventilation catheter or a supraglottic airway system such as laryngeal mask and the like.

This invention is a device to be used with a system for supplying anaesthetic or respiratory gases into the airway of a human or an animal. This device is a supraglottic airway device, which includes a shaft with three tubes one for ventilation purpose and rest two for dynamic cuff inflation and other for suctioning purpose. The dynamic cuff is inflated by the gases supplied directly from the anaesthesia or ventilator circuit through a specialised adaptor via dynalumen. The cuff inflation lumen (DynaLumen) will also be having a locking mechanism to enable its use like a conventional LMA; i.e., the cuff can be left continuously inflated both during positive pressure ventilation as well as less during expiratory phase and during spontaneous respiration.

An aerosol delivery system is disclosed that is a single-use (disposable) continuous nebulizer system designed for use with mechanically ventilated patients to aerosolize medications for inhalation with a general purpose nebulizer, or for connection with devices usable in endoscopic procedures. The system separates the liquid reservoir from the nebulization process taking place either at the adapter hub, where it fits into an endotracheal tube (ETT), or a gas humidifier, where the aerosol may treat a gas used in an endoscopic procedure, with a multi-lumen tube configured to nebulize liquid and air at its distal end. The refillable liquid reservoir is mounted away from the immediate treatment zone, avoiding orientation issues associated with other types of nebulizers having a self-contained reservoir. The system can produce aerosols having a wide range of droplet sizes, depending upon central lumen diameter, with values of MMAD that range from 4 to 30 m.

An apparatus to remove liquid from a ventilation system can include a housing, a first port extending into an interior volume of the housing and a second port extending toward the first tube, into the interior volume, separated from the first port by a gap that is at least 5 mm in length, such that ventilating fluid transfers from the first port to the second while secretions and condensate escape through the gap, to be trapped in the housing. The first port joins with a ventilator. The second port joins with an intubation tube coupled to a tracheostomy or endotracheal tube. An extraction port is in a floor of the housing so that accumulated liquids in the housing can drain downward and out the extraction port, while minimizing positive end expiratory pressure loss in the ventilation system, and without exposing caregivers to biological material in the drained liquid.

An add-on device and method for an Endo-Tracheal Tube (ETT), the add-on device including a lengthy body having a major arc-shaped cross section sized and shaped to tightly fit over an ETT, at least one longitudinal cavity passing along the lengthy body, including a distal suction cavity ending with a suction inlet at a distal end of the lengthy body; and a distal suction outlet channel extending from a proximal end of the lengthy body, the channel is a continuous extension of the distal suction cavity and configured to provide suction to the distal suction cavity. The add-on device senses moisture at a distal end of the add-on device, and in case of detection of excessive wetness, provides suction to the distal end of the device through a cavity passing along the device, the suction is provided via a suction outlet channel extending from a proximal end of the device.

An instrument for accessing and visualizing hollow organs is provided. The instrument includes a mouthpiece having a perforated mask and a sleeve having a generally cylindrical or ovoid shape extending from the perforated mask substantially perpendicularly thereto and defining a channel. The instrument further includes sucking means having a suction chamber or closed volume that is restrained to the mask on the side where the sleeve is formed. The suction chamber has a plurality of through openings adapted to allow fluid communication with a surrounding environment, an intake opening communicating with the suction chamber formed on the mask, wherein the through openings are formed on the skirt of a dome-shaped member which delimits the suction chamber.
