7 results about "Larynx" patented technology

The invention relates to a laryngeal tube (10) and proposes an improved design which has a positive effect on the use and manufacture of the laryngeal tube (10).

The application relates to the technical field of ultrasonic diagnosis, and provides a hyoid-larynx complex mobility evaluation method based on wearable ultrasound, which comprises the following steps: S1: collecting neck superficial tissue ultrasonic signals, continuously acquiring an ultrasonic image sequence containing hyoid and C2-C4 cervical vertebra anatomical structure images; S2: adopting a two-stage intelligent recognition and tracking strategy of initialization calibration+real-time tracking, automatically recognizing and continuously marking the position information of a point; S3: taking the line connecting the C2 cervical vertebra lower front edge point and the C4 cervical vertebra lower front edge point as a reference to establish a relative coordinate system; S4: based on the relative coordinate system, extracting real-time coordinates of a hyoid upper edge point in the whole process of a swallowing event, and calculating the position change amount of the marking point relative to the coordinate system; and S5: outputting the position change amount of the hyoid upper edge point as a core quantitative index of the hyoid movement amplitude. Relying on the scene advantages of ultrasonic noninvasive quantification and wearable devices, real-time, continuous and objective detection of hyoid displacement and related biomechanical parameters is realized.

Laryngeal tube (10) for ventilating a patient, with special geometry and a ventilation channel (18) through which both cuffs can be inflated and / or deflated.

The invention relates to a laryngeal tube (10) and proposes an improved design which has a positive effect on the use and manufacture of the laryngeal tube (10).

A Laryngeal oral airway (LOA) includes a mouthpiece flange defining two separate nostril-like openings in communication with separate elongated airways extending towards the larynx when in use. The nostril-like openings on the mouthpiece are spaced, shaped, and configured to snugly fit nasal prongs a nasal cannula therein, such that the nasal cannula is readily moveable between the patient's nostrils and the artificial nostril openings defined in the mouthpiece of the airway. The cannula is further secured by notches defined in the LOA.

The utility model provides a kind of laryngeal mask device with pressure detection of visualization, it is related to laryngeal mask device technical field, including cover body, the side of the cover body is provided with air pipe, still include the cuff of being located in the side of the cover body, the outside of the cuff is provided with monitoring assembly, the monitoring assembly is used for real-time monitoring the pressure of the cuff and patient contact part, through the cover plate connection multiple first pressure sensors are synchronously monitored, and through the monitoring structure of first pressure sensor, motor is controlled, to carry out inflation and deflation, multiple first pressure sensors are connected by cover plate, like a whole sensor, can carry out pressure monitoring to patient larynx in larger range.
