Methods and devices are provided for protecting cerebrovascular circulation from embolic fragments released during indexed surgery. The embolic protection filter is delivered in a reduced profile configuration via the access catheter and positioned on the aorta across the three major vascular openings leading to the cerebral circulation. Thereafter, the indexing surgical catheter is advanced through the same access catheter to perform indexing surgery. The indexing procedure may be transcatheter aortic valve replacement.

The invention provides a brain circulation time measuring method and device, a terminal and a storage medium, and belongs to the technical field of data information processing, and the method comprises the steps that a target file is acquired, and the target file comprises internal carotid artery time-intensity curve data and jugular vein time-intensity curve data after a user carries out intravenous injection of an ultrasonic contrast agent; determining a moment when the signal intensity of the internal carotid artery reaches 10% of the signal amplitude for the first time as a first time point; determining a moment when the signal intensity of the jugular vein reaches 10% of the signal amplitude for the first time as a second time point; and obtaining the brain circulation time based on the first time point and the second time point. By automatically processing the time-intensity curve data of the internal carotid artery and the jugular vein, the first time point and the second time point can be effectively identified, the cerebral circulation time is automatically calculated based on the two time points, and the accuracy and efficiency of cerebral circulation time measurement can be effectively improved.

The utility model provides a multi-mode stimulation device for promoting cerebral circulation, and aims to solve the problem of poor cerebral circulation improvement effect caused by single stimulation mode of equipment for promoting cerebral circulation in the prior art. A multi-mode stimulation device for promoting cerebral circulation comprises a glasses assembly which comprises a glasses frame and two glasses legs located on the left side and the right side of the glasses frame respectively, and the glasses frame is provided with two sets of LED lamp assemblies which correspond to the left eye and the right eye of a person respectively and emit light at the frequency of 40 HZ; the nose plug assembly comprises a mounting seat electrically connected with the glasses legs and two nose plugs arranged on the mounting seat, and a near-infrared lamp emitting light at the frequency of 40HZ is arranged in each nose plug; the earplug assembly comprises two earplugs capable of producing sound at the frequency of 40HZ, and the two earplugs are respectively arranged on the two glasses legs. According to the invention, through photoacoustic multi-mode synergistic stimulation, the effect of better improving the cerebral blood perfusion function can be achieved, so that the cerebral function is improved.

This invention discloses an intelligent state analysis method for anesthetized patients based on physiological data, comprising the following steps: S1, organizing and annotating historical anesthesia data to form executable state recognition rules and establishing a standardized historical case reference library. The beneficial effects of this invention are: by decomposing key interactive substructures such as nerve-circulation, brain-circulation, and respiration-perfusion from dynamic network profiles, coordinating indicators with clear physiological significance, such as baroreflex function index, brain oxygen-blood pressure coupling coefficient, and ventilation-perfusion matching degree, are calculated; these indicators can quantify the coordination of physiological systems under anesthesia from multiple dimensions; the system performs multi-dimensional similarity matching of these real-time indicators with an internalized anesthesia state knowledge base (containing multiple preset state modes), realizing accurate and interpretable independent determination of the anesthesia depth state in three dimensions: sedation, analgesia, and muscle relaxation, overcoming the limitations of traditional single index monitoring.
