An endoscopic system includes a processor. The processor generates from a measured value of pressure in a lumen of a subject a first temporal change image of the pressure in the lumen, generates an observation image for observing an opened/closed state of a valve portion in the lumen of the subject in real time from an image pickup signal obtained by picking up an image of the opened/closed state of the valve portion in the lumen in real time using an endoscope, and generates a superposition image by superposing the first temporal change image and the observation image in a temporally synchronized manner.

A method of method of high flow oxygen therapy (HFOT) and carbon dioxide (CO.sub.2) monitoring includes delivering high flow oxygen therapy (HFOT) via a central lumen of a nasal cannula, the nasal cannula comprising a proximal end, a distal end positioned within a pharynx region of a patient's airway, and the central lumen and a sampling lumen formed within a wall of the nasal cannula. The method also includes receiving sampled exhaled breath of the patient via the sampling lumen at a CO.sub.2 monitor, wherein the sampling lumen is configured to sample the exhaled breath at the pharynx region through the CO2-permeable membrane and direct the sampled exhaled breath to a CO.sub.2 monitor fluidly coupled to the sampling lumen and determining a level of CO.sub.2 in the exhaled breath using the CO.sub.2 monitor.

A fluid dispensing catheter includes an inner member defining a first passage and an outer member defining a second passage. The inner member is disposed within the second passage. The fluid dispensing catheter also includes a plug having a proximal section positioned within the first passage and a distal section extending distally from the proximal section. The distal section is positioned outside of the first passage and within the second passage.

Devices and methods for allowing for improved assisted ventilation of a patient. The methods and devices provide a number of benefits over conventional approaches for assisted ventilation. For example, the methods and devices described herein permit blind insertion of a device that can allow ventilation regardless of whether the device is positioned within a trachea or an esophagus.

The present invention provides medical devices comprising at least one visualization device sealed to, attached to or otherwise combined with at least one of the following second devices: an oral airway, ventilating mask, urinary catheter, trocar, a tool tube, and a medical glove. The present invention also provides methods for rapid and accurate placement of a medical device in a patient and continuous real time monitoring, including a remote monitoring, of the patient after the placement.

An endotracheal tub includes at least one main tubular body, which is configured for at least partial insertion into the respiratory tract of a patient, through the mouth or the nose. The tube includes at least one tubular reinforcement skeleton for the body. At least one useful portion of the skeleton is constituted by at least one first filament which is wound in a helical manner around the longitudinal axis of the body and is selectively disengageable from the body. Such disengagement enables its removal after the completion of the step of insertion of the body into the respiratory tract of the patient.

A respiratory mask can be used to provide therapy to patients who also require a nasogastric (NG) tube. The mask seal can include a path that is designed to deform around an NG tube or other without lifting the mask away from a patient's face. The deforming path can help to minimize gaps that form between the patient's face and the mask seal as a result of the tube, thus reducing leaks and improving the efficacy of the treatment.

The present invention provides a delivery device for intranasal administration of topical therapeutic agents to a desired site within a nasal cavity. The delivery device, in some embodiments, comprises a housing defining an interior and adapted to contain a supply of at least one therapeutic agent. The delivery device further includes a flexible connector, which is in fluid communication with the supply in the housing. A distributor, which is also integrally formed with the connector, is also provided. The distributor includes a proximal end that is in fluid communication with a distal end of the connector, and is adapted to receive the supply of the at least one therapeutic agent delivered by way of a conduit. The distributor further includes a distal end defining an outlet configured to diffuse the therapeutic agent when delivered to the treatment site.

The present application discloses a bridle device and a method of placing a bridle on a person using the bridle device. In one exemplary embodiment, the bridle device comprises a retrieval portion and a delivery portion. The delivery portion has a retrieval member and a retrieval magnet attached to the retrieval member. The delivery portion has a delivery member and a delivery magnet that is movable relative to a distal portion of the delivery member. In certain embodiments, the delivery portion has a delivery tube and a delivery magnet attached to a flexible elongated member received in the delivery tube. The delivery magnet is movable relative to a distal portion of the delivery tube and both poles of the delivery magnet are exposed outside of the delivery tube.

Devices, systems, and methods of facilitating airway management with reduced risk of release of droplets and aerosolized pathogens from the lungs of a patient are disclosed, including a bronchoscope adapter for an endotracheal tube, an endotracheal tube with integral bronchoscope adapter, an endotracheal intubation mask system, a laryngeal mask airway-specific mask system, and a quick-seal laryngeal mask airway-specific mask system.
