Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a head-mounted monitoring headframe that is convenient to wear. Background Art

[0002] The utility model background of the head-mounted monitoring headframe for electroencephalogram (EEG), cerebral oxygenation (TCD) is related to multiple important medical and technical fields. This integrated monitoring technology combines electroencephalogram (EEG), cerebral tissue oxygenation monitoring (NIRS), and transcranial Doppler (TCD) technologies to provide comprehensive monitoring of the patient's brain state. The following are several key areas behind the development of this technology: Electroencephalogram (EEG) technology: Electroencephalogram is a method of recording the electrical activity of the brain. By placing electrodes on the scalp to monitor the electrical activity of the brain, it is crucial for diagnosing and monitoring various brain diseases, such as epilepsy, sleep disorders, and brain injuries. The progress of EEG technology provides higher resolution and accuracy for real-time monitoring of brain electrical activity. Cerebral tissue oxygenation monitoring: Near-infrared spectroscopy imaging (NIRS) is a non-invasive technology used to monitor the oxygenation level of cerebral tissue. NIRS is achieved by measuring the absorption of near-infrared light on the scalp and skull. This technology is very useful for evaluating cerebral blood flow and oxygenation status, especially in surgical and intensive care settings. Transcranial Doppler (TCD) technology: TCD is a technology that uses the principle of ultrasonic waves to evaluate the blood flow velocity of cerebral blood vessels and is used to evaluate cerebral hemodynamics. It is very valuable for diagnosing and monitoring conditions such as intracranial hypertension, vascular stenosis, or occlusion.
