Description

Technical Field

[0001] This application relates to the field of smart wearable technology, and in particular to a swimming cap that can monitor brain activity and has Bluetooth functionality. Background Technology

[0002] Currently, swimming caps with drowning warning functions typically use water pressure sensors to monitor parameters such as time spent in the water and water pressure to determine if the person is drowning. If drowning is detected, a distress signal is sent to a designated number via a remote communication module. However, in practical use, this solution cannot identify drowning victims in a timely manner. First, because the depth of the pool is fixed when swimming in a swimming pool, the water pressure is also fixed, making it impossible to accurately determine whether a person is drowning using water pressure sensors. Second, to prevent excessive false alarms, determining whether someone is drowning requires the sensor to detect sufficient time in the water. If the distress signal is sent too late, it often fails to achieve the best rescue effect.

[0003] At the onset of drowning, panic and struggle cause a state of tension, leading to a temporary increase in alpha and beta waves in the brain due to stress response. As drowning continues, the body begins to experience oxygen deprivation, affecting brain function. At this point, theta waves gradually appear and increase in brainwaves. Theta waves typically appear when the brain is drowsy, in a light sleep, or when cognitive function is somewhat inhibited. This indicates a decline in brain metabolism and function, a gradual blurring of consciousness, and a weakened ability to perceive and react to the surrounding environment. Due to continued oxygen deprivation, normal brain function cannot be maintained, and the alpha and beta wave activity that initially increased in the early stages of drowning gradually weakens, with reduced amplitude and slower frequency, reflecting a continuous decline in the brain's level of arousal and concentration.

[0036] See Figure 1 , Figure 1 This invention provides a swimming cap that can monitor electroencephalograms (EEGs) and has Bluetooth functionality, as shown in an embodiment of this application.

[0037] This double-layer swimming cap consists of an outer waterproof layer 1 and an inner skin-friendly layer 2, which are connected by ultrasonic welding. The cap also features elastic bands 3 along the edges. The outer waterproof layer 1 is made of neoprene rubber, and the inner skin-friendly layer 2 is made of antibacterial Lycra fabric.

[0038] The electroencephalogram (EEG) monitoring component includes a flexible waterproof disc electrode 4, which is disposed in the inner skin-friendly layer 2.

[0039] The main control unit housing 5 has a working indicator light 6 on its surface and encapsulates a signal processing module, a data communication module, and a wireless charging module inside. Specifically, one main control unit housing 5 is located on each of the left and right sides of the double-layer swimming cap.

[0043] Specifically, before wearing and using the swim cap, you can check the remaining battery level using a mobile phone or computer. Simply place the swim cap next to the Bluetooth charging pad to charge, avoiding water ingress issues caused by charging with a wired connection. During charging, the receiving coil 14 in the swim cap generates an induced current, which is filtered by the second filter 17 and then reaches the rectifier unit 15 (rectifier unit 15 is the CV8045D rectifier circuit mainboard). It is then integrated by the switching regulator 18 and reaches the charging management unit 16 (charging management unit 16 is the BQ51013B charging management circuit mainboard). After analysis, the charge reaches the battery 13 to complete charging.

[0044] In this embodiment, the interface of the amplifier circuit 7 is a serpentine trace. The serpentine trace can reduce the stress on the conductors caused by the user's head movements, extend the conductor life, and reduce the probability of short circuits or poor contact.

When the pin at the end of the lead wire 20 is inserted into the spring needle socket 21, the pin is compressed, the spring stores force, and the continuous pressure of the spring ensures that the pin and the pin tip maintain close contact during swimming and shaking, avoiding signal interruption.

[0052] (2) The flexible waterproof disc electrode 4 monitors the user's brain current. The current is transmitted to the amplifier circuit 7 of the signal processing module via the lead wire 20 to amplify the weak brain current. Then the current is transmitted to the microcontroller 9 with an integrated analog-to-digital converter via the first filter 8 for analysis.

[0053] (3) When the theta / alpha ratio of brain waves is between 2.0 and 2.7, this device will issue an alarm signal. Specifically, the alarm signal is transmitted to a mobile phone or computer via the built-in antenna 12 after integration through a Bluetooth chip. The alarm signal includes the location of the drowning person, and the working indicator light 6 emits a red light that can clearly penetrate the water medium, so that rescuers can accurately locate the drowning person and carry out rescue as soon as possible.
