The Respiratory Interface Device is a novel, mouth-inserted airway management tool designed to facilitate both oxygen delivery and carbon dioxide sampling through an integrated oral pathway. Unlike conventional nasal cannulas or oropharyngeal airways, this device features internal channels configured to house standard or capnography-compatible tubing, allowing simultaneous gas delivery and exhaled gas monitoring. The device includes a contoured dental plate and an airway arch that conforms to the patient's hard palate, maintaining upper airway patency while avoiding stimulation of the protective airway reflex. Its ergonomic design supports a secure oral fit and provides a streamlined interface for procedural sedation, monitored anesthesia care, emergency airway support, and alternative oxygenation strategies in patients where nasal access is limited or contraindicated. The Respiratory Interface Device represents a versatile, dual-function solution for enhanced airway management and respiratory monitoring.

This invention relates to the field of data processing technology and discloses a multi-granularity respiratory signal statistical inference and sleep staging decision-making system. The system comprises a signal acquisition and buffering module that segments a continuous respiratory acoustic signal sequence into continuous analysis windows; a multi-dimensional feature extraction module that extracts multi-dimensional observation feature vectors containing respiratory rate variation features and cross-window respiratory trend features; a dynamic transition probability generation module that acquires global sleep onset time parameters and continuous dwell time parameters, performs numerical updates on the initial state transition probability matrix, and generates a dynamic state transition probability matrix; and inputs the multi-dimensional observation feature vectors and the dynamic state transition probability matrix into a Markov model to calculate the posterior probability and output the classification result. This invention overcomes the aftereffect defect of static Markov models by reconstructing the state transition matrix through spatiotemporal dual variables, achieving accurate anti-disturbance and state locking against transient noise disturbances.

This application provides an animal ventilation device, including a breathing circuit, an anesthesia dispenser, a controller, and a control receiver. The control receiver outputs the received ventilation mode and / or ventilation parameters to the controller. The breathing circuit includes an inspiratory drive module, an inspiratory branch, an expiratory branch, and a breathing interface. The two ends of the inspiratory branch are connected to the inspiratory drive module and the breathing interface, respectively, and the expiratory branch discharges the received exhaled gas. The inspiratory branch has a first port and a second port. The anesthesia dispenser includes an inlet interface and an outlet interface. In the respiratory support mode, the first port and the second port of the inspiratory branch are connected, and the inspiratory drive module outputs an inspiratory auxiliary airflow through the inspiratory branch and the breathing interface. In the anesthesia mode, the inlet interface and the outlet interface of the anesthesia dispenser are connected to the first port and the second port in the inspiratory branch, respectively, and the inspiratory drive module and the anesthesia dispenser output an inspiratory auxiliary airflow containing anesthetic through the inspiratory branch and the breathing interface.

This invention belongs to the field of medical device technology, specifically relating to a bidirectional high-flow humidified oxygen therapy mask with a shunt air supply structure, comprising a mask with an installation groove and a sealing groove on the front end face, the sealing groove surrounding the outside of the installation groove. This invention achieves bidirectional coordinated air supply of high-frequency jet from the nasal cavity and low-frequency diffusion from the oral cavity through the claw-shaped nasal cannula and the bottom diffusion hole of the shunt plate, structurally eliminating ineffective mixing of airflow between the mouth and nose. Simultaneously, the double seal of the integrated silicone lip and sealing ring plate stably controls the airflow leakage rate of mouth-breathing patients to ≤5%, effectively reducing PEEP value fluctuations and inhaled oxygen concentration fluctuations to ≤±5%, significantly improving oxygenation and reducing the rate of endotracheal intubation. Furthermore, the active diffusion oxygen supply design in the oral cavity reduces the incidence of oral mucosal dryness and sputum crust formation by more than 80%, significantly improving treatment safety.

This invention discloses a respiratory guidance device and its control method and system, relating to the field of medical device technology. The device includes a gas supply unit, a disposable lip-holding tube, an exhalation detection module, and a feedback module. The lip-holding tube has a middle lip-holding section with a breathing port. When the patient is in working condition, they hold this lip-holding section with their lips, the breathing port being located between the lips and outside the teeth, allowing the upper and lower teeth to close normally, achieving natural swallowing without stress on the masseter muscle. The gas supply unit provides a constant flow of clean gas, the exhalation detection module collects the patient's expiratory flow rate in real time, and the feedback module provides guidance prompts based on the expiratory status, helping the patient adjust to the correct oral breathing mode in real time. This invention, through its unique lip-holding tube design and intelligent feedback guidance, fundamentally solves the problem of nasal exhalation causing endoscope fogging during endoscopic examinations, significantly improving patient comfort and compliance, and can be extended to scenarios such as nebulizer therapy and postoperative monitoring.
