AI Technical Summary
Existing breathing feedback systems are cumbersome and require digital processing or software, lacking immediate visual feedback for unconscious breathing pattern recognition and adjustment.
An analog breathing biofeedback device with a breathing sensor, electronic control unit, and LED display provides direct visual feedback without delay, allowing users to recognize and modify breathing patterns through contactless visualization.
Enables users to improve body awareness and self-regulate breathing for relaxation and stress management with immediate visual feedback, suitable for both therapeutic and everyday use.

Abstract
Description
[0001] The invention relates to an analog breathing biofeedback device for providing visual feedback on a user's breathing pattern, in particular for supporting breathing exercises, relaxation techniques or therapeutic applications.
[0002] The analog breathing biofeedback device described here consists of a breathing sensor (5) that registers the breathing movement, an electronic control unit (7) that processes the movement, and an LED display (4) that provides the user with direct visual feedback of the breathing movement without delay.
[0003] This feedback enables the person to recognize unconscious breathing patterns and to change them in a targeted manner, for example to learn deeper abdominal breathing.
[0004] The goal is to improve body awareness and develop skills for self-regulation of breathing, which can lead to relaxation and / or better stress management.
[0005] The control unit (7) is placed at the head end or to the side of the person lying on their back, the LED display (4) is positioned approximately 10cm above the user's eyes using a 60cm long gooseneck bracket (3) which is attached to the control unit (7).
[0006] This allows for contactless visualization of breathing movements (no bothersome glasses or similar devices required).
[0007] The sensor (5) is placed on the user's abdomen and lightly secured with a Velcro strap (6).
[0008] After connecting the sensor (5) to the control unit (7) and connecting the power supply, the basic brightness is adjusted to the desired zero point by means of a trim screw (2) located on the control unit (7), so that the LED indicator (4) is off during complete expiration (breathing out).
[0009] The brightness of the LED display (4) changes depending on the breathing movement: • The brightness of the light increases when inhaling, • It decreases when exhaling.
[0010] This gives the user immediate visual feedback without digital signal processing or software.
[0011] The system is portable, easy to use and suitable for use in both therapy and everyday life. Reference symbol list 1 power supply unit with cable 2 Trim screw 3 gooseneck brackets 4 LED display 5 Sensor with cable 6 Velcro straps 7 Control unit
Claims
Analog Respiratory Biofeedback Device: The invention relates to an analog respiratory biofeedback device for visualizing the respiratory rate or breathing movement of a person, characterized in that the breathing movement of the user is detected by a sensor (5) lying on the stomach and lightly attached with a Velcro strap (6). A strain gauge built into the sensor (5) records the breathing movement of the person and transmits the signal to a control unit (7), which amplifies the signal proportionally and transmits it analogously to an LED display (4). Analog breathing biofeedback device characterized by the fact that the sensor (5) can be considered low-contact, as it only rests lightly and thus does not exert any disturbing pressure on the abdomen. It is made of ABS plastic and is tapered in the middle area for more precise and easier stretchability. Analog breathing biofeedback device characterized in that the visual feedback is transmitted directly to the user in an analog format, without delay, digital signal processing, or software. The signal, amplified by a control unit (7), is transmitted to an LED display (4) consisting of two LEDs positioned at eye distance, the brightness of which changes depending on the breathing movement: • The brightness increases during inhalation, • it decreases during exhalation. Analog breathing biofeedback device, characterized by its ease of use: After connecting the power supply (1) and the sensor (5) to the control unit (7), the sensor (5) is easily fastened around the abdomen using a Velcro strap (6). A trim screw (2) on the control unit (7) is used to adjust the base brightness to the desired zero point, so that the LED display (4) is off during complete expiration (exhalation). The control unit (7) is placed at the head of the user or on the side of the head. The LED display (4) is positioned approximately 10 cm above the user's eyes using a gooseneck mount (3) on the control unit (7). The different connectors prevent incorrect connections.
