A mechanical ventilation device comprising at least one electronic controller configured to receive imaging data and transpulmonary pressure data associated with a lung of a patient; perform deformable image registration of the inhalation image and the exhalation image to produce a relative compliance or elasticity map of the lungs; convert the relative compliance or elasticity map of the lungs to a quantitative compliance or elasticity map of the lungs based on the inhale transpulmonary pressure and the exhale transpulmonary pressure; and display the information relating to or derived from the quantitative compliance or elasticity map on a display device.

A respiratory monitoring device includes an electronic controller configured to: analyze an audio signal triggered during inspiratory and expiratory phases of a patient receiving mechanical ventilation therapy from a mechanical ventilator, the audio signal being acoustically coupled into the airway of the patient, to determine resonant frequencies of the airway; determine a shift in the resonant frequencies between the inspiratory and expiratory phases to determine a presence of pendelluft inside of a lung of the patient; and output an indication of the presence of pendelluft.

Oral gas catheters and methods of inducing gas in a patient orally. The oral gas catheter includes one or more delivery cannulas configured to be inserted into the patient's mouth with a distal end of the delivery cannula disposed adjacent the patient's laryngeal inlet, and a clip disposed on the delivery cannula. The clip is configured to secure the delivery cannula to a tooth of the patient. The oral gas catheter may have two such delivery cannulas and clips with the delivery cannulas coupled together by a coupler. The delivery cannulas are placed in an operative position in a patient's mouth and secured in the operative position by releasably securing the clips to the patient's teeth. The oral gas catheter makes it possible to bypass the nasal cavity and deliver oxygen or other gas directly adjacent the laryngeal entrance and into an anatomical dead space of the airway.

The present invention provides an improved visual laryngeal mask comprising a tube, an end of the tube is provided with a fixing seat. The fixing seat is provided with an airbag, and the fixing seat has a recess which is provided with an airway opening. An imaging cavity extends longitudinally inside an inner wall of the tube. The imaging cavity has a built-in imaging device, and the imaging cavity protrudes forward relative to the airway opening to form a stopper which prevents an epiglottis from blocking the imaging device. A front end of the stopper is concaved to form a recess, and an opening of the imaging cavity is located at a low point of the recess.

The invention relates to a mouthpiece for a product dispensing device including a product dispensing duct defining a longitudinal axis and including a connection opening designed to be connected to a dispensing member of the product dispensing device, and a dispensing opening designed to open freely into the mouth of a user, and a lingual cavity designed to receive at least one end of the tongue of the user, including a lingual opening allowing the tongue to be inserted into the lingual cavity and a contact surface designed to form a target for one end of the tongue of the user.

The invention also relates to a product dispensing device and to a method for dispensing a product.

A Stylet device that allows for the articulation of tubing and provides a method for positioning of the tubing during intubation or other procedures while the tubing is located within a passage-way or lumen of a subject, such as an airway, organs, veins, intestines and the like. Where unique anatomical conditions are present in a subject, rendering standard intubation devices inadequate, the articulation capabilities of the apparatuses of the current invention are of particular use during methods of use and further promote the non-occlusion of the central cavity of the tube.

The present invention relates to a device for a respiration arrangement. The device comprises a conduit having a first opening connectable to an air/gas source such as a resuscitation bag, and a second opening connectable to a face mask, such that a fluid pathway along a longitudinal direction of the conduit is established from the first opening to the second opening. The device further comprises a flow constriction, arranged in the conduit which upon fluid flow through the conduit results in a pressure difference over the flow constriction, the flow constriction at least partly comprising a laminar flow section, wherein the device further comprises at least one pressure connecting port arranged in pressurized communication with fluid between the flow constriction and the first opening, and wherein the pressure connecting port is arranged in the longitudinal direction of the conduit.

A liquid ventilation system includes a reservoir holding a perfluorochemical (“PFC”) fluid, and a suction pump connected to the reservoir to reduce pressure within the reservoir. A sensor is configured to measure an intra-lung pressure. An appliance is configured to be disposed within a patient. The appliance carries an injector to supply the PFC fluid through the appliance. An extraction valve is disposed on an extraction line between the appliance and the reservoir. The extraction valve is arrangeable between a first position enabling fluid communication from the appliance to the reservoir and a second position disabling fluid communication from the appliance to the reservoir.
