A method for controlling tissue temperature involves providing a nasal cannula including a first elongated prong with an axial fluid channel and a downwardly-curved shape. The nasal cannula further includes a first aperture on a side wall of a distal portion of the first elongated prong. The first aperture provides access to the axial fluid channel. The method includes inserting the first elongated prong into a nasal cavity of a subject to face the first aperture at a pharyngeal wall of the subject and modifying a temperature of the pharyngeal wall by delivering a first fluid portion through the axial fluid channel and out of the first aperture to the pharyngeal wall.

A supraglottic device (SGD) comprising an airway tube (1) extending to a bowl-shaped cuff (2) located at a distal end of the airway tube, the cuff orifice being in the shape of a sealing ring (3) for sealing between the laryngeal and pharyngeal walls, the dorsal portion of the cuff on the opposite side of the cuff aperture comprises at least one open groove (4) on the left or right side of the dorsal portion of the cuff for insertion of a gastrointestinal device through any of the open grooves. Methods and kits for using the supraglottic device are also provided.

The present invention provides a hyoid-laryngeal suspension device and system for treating sleep disordered breathing (SDB). The device includes a first fastener, the size and structure of which are set to anchor to the patient's hyoid bone or thyroid cartilage, and a second fastener, the size and structure of which are set to anchor to the patient's sternum, clavicle or ribs. One end of a static member or elastic member is connected to the first fastener, and the opposite end is connected to the second fastener. The elastic member has sufficient elasticity to dynamically elevate the pharynx and / or larynx to allow speaking and swallowing. The static member has sufficient tension to maintain appropriate pharyngeal wall tension while still allowing sufficient movement of the hyoid bone and thyroid cartilage to achieve speaking and swallowing functions.

The invention belongs to the technical field of medical rehabilitation equipment, and discloses a postoperative intelligent monitoring rehabilitation auxiliary instrument for the laryngeal pharynx and a control method. The method includes: acquiring pharyngeal physiological data of the pharyngeal of a patient; the method comprises the following steps: constructing a physical information neural network model, inputting a four-channel tensor formed by processing pharyngeal physiological data into the physical information neural network model for analysis, outputting a laryngeal closure degree and a pharyngeal wall tissue elastic modulus, and determining a patient pain level based on the laryngeal closure degree and the pharyngeal wall tissue elastic modulus; on the basis of analysis of mucous membrane dynamic displacement sequence data and pressure data, swallowing mode characteristics of the patient are determined, rehabilitation decision analysis is conducted in combination with the laryngeal closure degree, the pharyngeal wall tissue elasticity modulus and the pain level, and a rehabilitation intervention instruction is generated; the drug administration operation is executed based on the rehabilitation intervention instruction, the execution feedback record after the drug administration operation is completed is obtained, the rehabilitation intervention instruction is adjusted based on the execution feedback record, and the timeliness and effectiveness of a treatment decision are remarkably enhanced.

The present application belongs to the technical field of medical rehabilitation equipment, and discloses a kind of laryngeal postoperative intelligent monitoring rehabilitation auxiliary instrument and control method;Including obtaining the physiological data of the throat of patient throat;Four-channel tensor formed after processing physiological data of throat is input into physical information neural network model for analysis by constructing physical information neural network model, and the output of laryngeal entrance closure degree and pharyngeal wall tissue elastic modulus, determine the pain level of patient based on laryngeal entrance closure degree and pharyngeal wall tissue elastic modulus;Based on the analysis of mucous membrane dynamic displacement sequence data and pressure data, determine the swallowing mode characteristics of patient, and combine laryngeal entrance closure degree, pharyngeal wall tissue elastic modulus and pain level to carry out rehabilitation decision analysis, generate rehabilitation intervention instruction;Based on rehabilitation intervention instruction, execute dosing operation, and obtain the execution feedback record after completing dosing operation, adjust rehabilitation intervention instruction based on execution feedback record, significantly enhance the timeliness and effectiveness of treatment decision.

A system and methods for stimulating two or more nerves to treat obstructive sleep apnea includes an implantable nerve stimulator (e.g., an implantable pulse generator) with a single current source for generating a time-multiplexed signal. The time-multiplexed signal includes first pulses defined interleaved with second pulses. The first and second pulses are defined by respective sets of pulse parameters stored in memory. The processor controls at least one switch to selectively steer each first pulse to a first nerve and each second pulse to a second nerve. In some examples, the first and second nerves are selected from a group of nerves consisting of the ansa cervicalis, the phrenic nerve, and the hypoglossal nerve.
