The invention discloses a multi-tube body adapter which is connected to a plurality of outer tubes for application to a digestive system and a respiratory system of a human body. The multi-tube body adapter includes a housing to form an accommodating space of the multi-chamber. The plurality of chambers is not in communication with each other. One end of the plurality of chambers respectively provides a connection port and the other end of the plurality of chambers is commonly connected to an extension having a plurality of openings. By connecting with the chamber, the connection port and the opening, a supply path for separately providing the supply path of the respiratory system and the digestive system can be formed.

An airway management device (10) for a human or animal subject (20) includes an airway tube (101) having a first end for disposal external to the subject (20) and a second end (102) for disposal in a portion of an airway of the subject (20). A light emitting element (108) and a photo-sensing element (109) may be disposed at the second end (102) of the airway tube (101). The light emitting element (108) may be configured to transmit light to tissue adjacent to the light emitting element (108). The photo-sensing element (109) may be configured to receive reflectance spectra (204) from the tissue. The location of the second end (102) of the airway tube (101) may be determined from characteristics of the reflectance spectra (204) of the tissue.

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. In addition, the methods and device allow for timed delivery of ventilations based on a condition of a thoracic cavity to increase the amount and efficiency of blood flow during a resuscitation procedure.

Provided are an ultrasound diagnostic apparatus and a method of controlling an ultrasound diagnostic apparatus that can more reliably confirm the presence or absence the esophageal intubation regardless of the skill of the user. An ultrasound diagnostic apparatus (1) includes an ultrasound probe (15) used for observing a trachea and an esophagus of a subject, an image acquisition unit (8) that transmits an ultrasound beam toward the subject from the ultrasound probe (15) to acquire an ultrasound image, an observation target detecting unit (9) that detects the trachea and the esophagus included in the ultrasound image by performing image analysis with respect to the ultrasound image, an operation guiding unit (11) that guides a user to operate the ultrasound probe (15) such that the ultrasound probe (15) is positioned at a position suitable for observation of the observation target detecting unit (9), and an esophagus state determination unit (10) that determines whether a tracheal tube is inserted into the detected esophagus.

Systems, methods, and devices are disclosed for accurately detecting a position of an endotracheal tube by sensing patient anatomy surrounding the endotracheal tube. Systems of the present disclosure include an endotracheal tube having at least one sensor supported by the endotracheal tube configured to detect surrounding patient anatomy. A signal processing unit can receive data from the sensor and can at least one of (i) identify the detected patient anatomy, for example, vocal cords, (ii) determine a distance between the detected patient anatomy and a known point on the endotracheal tube, and (iii) verify a positioning of the endotracheal tube within a tracheal or esophageal lumen of the patient. In some embodiments, the system can include at least one inflatable component that can extend along an outer surface of the endotracheal tube and support the at least one sensor.

A position monitoring system is provided that includes a tracheal tube having a distal portion with a radiopaque indicator. The tracheal tube is configured to be positioned within an airway of a patient. The position monitoring system also includes an external sensor configured to be positioned on an external surface of the patient. The external sensor includes an emitter configured to transmit energy into the patient and toward the distal portion and a detector configured to receive a reflected portion of the energy to permit identification of a position of the distal portion. The position monitoring system, in certain embodiments, further includes a video laryngoscope communicatively coupled to the external sensor. The video laryngoscope includes a display and a processor, and the processor is configured to instruct the display to present an indication of the position of the distal portion based on feedback from the detector.

An integrated multimodal colorimetric based aspiration detection and intubation placement verification system for an endotracheal tube and associated method includes a housing configured to be coupled to the endotracheal tube whereby patient exhalation can flow through an internal passage of the housing, and colorimetric based sensors within the housing and configured to come into contact with the patient exhalation, where the colorimetric based sensors are visible from the exterior of the housing, and wherein the colorimetric sensors include at least two of i) CO2 sensor, ii) a sensor for a first gastric acid, iii) a sensor for a second gastric acid different from the first gastric acid, and iv) a PH sensor. An associated method is disclosed. The integrated multimodal colorimetric based system can be used with other respiratory devices other than endotracheal tubes.

This disclosure provides an endotracheal tube with a tip suitable for traversing the laryngeal inlet and with a guiding channel having a proximal opening adjacent a proximal end portion and a distal opening adjacent to a tip, wherein the guiding channel is adjacent a sidewall of the main lumen of the tube, which allows more accurate wire-guided intubation of a patient, a method and a kit relating to the same.

Certain embodiments are directed to a bougie device and methods of use thereof, the device directing the deployment of an endotracheal tube through the larynx.
