An Advanced Airway System Nasopharyngeal Injector is used to reduce the size of a Nasopharyngeal tube significantly. The Nasopharyngeal tube is folded in half. The Advanced Airway System Nasopharyngeal Injector will slide down the middle of the tube, locking a portion of the Nasopharyngeal tube into the track groove (104). The Nasopharyngeal tube reduction in size allows the tube to pass through the nasal passageway, decreasing discomfort and preventing debris from entering the tube. Once the Nasopharyngeal tube is administered into the passageway, it unfolds to fill the nasal passage. The Advanced Airway System Nasopharyngeal Injector uses a one-size-fits-all nasopharyngeal tube made from various materials or additive manufacturing to reduce weight and give the Advanced Airway System Nasopharyngeal Injector flexibility and durability.

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.

Several methods of supporting respiratory function of a patient before, during and/or after a medical procedure are disclosed. In certain arrangements, supporting respiratory function while a patient is under general anaesthesia can include providing a high gas flow that is greater than 15 L/min while the patient is under general anaesthesia. In certain arrangements, a method of providing ventilation while a patient is under general anaesthesia involves providing only a gas flow delivered through a nasal interface that is greater than 15 L/min while the patient is under general anaesthesia.

The present disclosure provides methods of accurately placing a gastric tube, such as an orogastric tube or a nasogastric tube, in an esophageal orifice of a subject using an airway visualization system.

An endopharyngeal airway positive pressure ventilation device and method of use for ventilating a patient through a nasopharyngeal airway in surgical settings that is incapable of normal ventilation with current anesthetic techniques due to a risk for airway obstruction in surgical procedures requiring conscious sedation monitored anesthesia care (MAC). The invention includes a single-lumen endopharyngeal nasal tube with an eye shaped opening at its distal end and a cylindrical proximal end used as an adaptor for anesthetic applications such as positive airway pressure via JACKSON-REES modified ambu-bag or other various anesthesiology applications. Contiguous to the distal end of the nasal tube is an end-tidal CO2 monitoring port (ETCO2). On the distal end of the flexible nasal ventilation tube is an eye opening allowing air flow to the posterior pharynx. The device further includes a modified JACKSON-REES ambu bag which allows for controlled airflow to the patient during a REESE procedure.

An oxygen catheter for veterinary patients includes an integrated catheter, cannula or vessel having integrated lumens for both oxygen and anesthetic such as lidocaine. The oxygen lumen extends into the trachea of the veterinary patient, often a canine, for respiratory aid. The anesthetic lumen is integrated into the same catheter as the oxygen, and terminates prior to the oxygen lumen for administering an anesthetic such as lidocaine around the soft palate to ease discomfort of the inserted catheter. The integration of the respiratory and anesthetic vessels allows a lidocaine drip to accompany the catheterized oxygen supply to medicate the tracheal, pharynx and soft palate regions from the inserted catheter along the path of the oxygen lumen to ease patient discomfort and anxiety for effective respiratory treatment while avoiding more invasive and expensive measures.

Some implementations of the disclosure are directed to a balloon dilator system, including: a hand piece including an attachment mechanism for removably coupling to a proximal end of an endoscope; a hole for inserting a distal end of a balloon catheter including an inflatable balloon; and a hollow tube distally extending from the hand piece, a proximal end of the hollow tube configured to receive the balloon catheter inserted through the hole and advance the balloon catheter such that the distal of the balloon catheter exits a distal end of the hollow tube. The hand piece may include a pump handle that, when actuated, pumps pressurized fluid to inflate the inflatable balloon.

An intubation apparatus and, method of use, for intubating a patient. The apparatus includes an airway ventilation device having tubing located between an inlet end and an outlet end, the outlet end being configured to be locatable in the airway of a patient, intermediary tubing having a first end releasably connectable to the inlet end of the airway ventilation device and a second end having a fitting configured to connect to a gas supply, and an introducer having a first end that is alternatively releasably connectable to the first end of the intermediary tubing and a second end having a blunt tip.

A process, a signal processing unit and to a ventilator automatically calculate a set point for a frequency, with which the ventilator performs ventilation strokes and thereby mechanically ventilates the patient. An alveolar or proximal minute volume is predefined. A lung time constant for the lungs of the patient is determined. The volume of a dead space in a fluid connection between the lungs and the ventilator is determined. A mandatory frequency set point (f.sub.set,mand) for the mandatory ventilation of the patient is calculated. An ideal frequency (f.sub.spon), with which the patient can achieve the minute volume by means of spontaneous breathing, is calculated. The ventilation frequency set point is calculated as a weighted average of the mandatory frequency set point (f.sub.set,mand) and of the ideal frequency (f.sub.spon). The averaging depends on a determined actual intensity of the spontaneous breathing of the patient.

A system for measuring cardiovascular data includes an elongate member having a channel, a first expandable member carried by the elongate member and movable between a collapsed state and an expanded state by adjustment initiated externally of a subject, a first sensor disposed on a surface of the elongate member, second and third sensors disposed on a surface of the first expandable, a first optical sensor located at a first location in relation to the distal end of the elongate member and configured for obtaining photoplethysmographic data, and wherein the first expandable member in its expanded state is configured to interface with the subject's larynx for delivery of at least oxygen gas into the respiratory system of the subject, and the second and third sensors are configured to contact tissue in proximity to the larynx when the first expandable member is in its expanded state.
