Patient alarm system with head movement detection
A recently granted patent (Publication Number: US11972673B2) discloses a system designed to assist patients in raising alarms by detecting head movements. The system includes a sensor positioned at the patient's head region to detect head movement and a patient assisting device with a processor and memory storing instructions to categorize alarm values, receive signals from the sensor, determine alarm states, and generate alarms based on these states. The sensor can be equipped with a three-axis accelerometer or a gyroscope sensor to accurately detect movements like head nods or shakes, which are then used to determine the alarm state categorized into low, medium, or high priority levels for appropriate response.
Furthermore, the patent also covers a ventilation mask with a similar sensor and transceiver to transmit detected head movements to an alarm generating device for categorization and alarm generation. The method outlined in the patent involves categorizing alarm values based on sensitivity settings, comparing them with threshold values, receiving signals from the sensor, determining alarm states, and generating alarms accordingly. Parameters like the number, speed, and duration of head movements are considered in determining the alarm state, which is then used to trigger alarms of varying priority levels. This innovative system aims to provide timely assistance to patients by leveraging head movement detection technology to enhance alarm responsiveness and patient safety.
