Description

Device for Virtual Heart Rate and Driving Method Thereof

The present invention relates to a virtual heartbeat device and a method of driving the same, and more particularly, by generating vibrations similar to the heartbeat of the heart by being located, for example, in a user's heart region, thereby stabilizing blood pressure and reducing stress by reducing the actual heart rate. The present invention relates to a virtual heartbeat device and a method of driving the device.

Many non-pharmacological methods, products and services exist to reduce stress or blood pressure. Typically, yoga or meditation is a method that involves a lot of time, money, and effort, or products using biofeedback technology, such as regular carotid stimulation, deep breathing training, and blood pressure stabilization through grip training, have been developed. However, these methods require the will and effort, which are artificial actions, and the instantaneous effect is maximized, but there is a limitation that it is difficult to sustain without external help.

Therefore, in recent years, in order to stabilize blood pressure and reduce stress, there is an urgent need to develop a new technology rather than a method that requires will and effort like the existing deep breathing training or meditation methods.

1 is a diagram illustrating a virtual heartbeat system according to an embodiment of the present invention, and FIGS. 2A and 2B are diagrams for explaining a process of reducing blood pressure and relieving stress by virtual heartbeat vibration.

As shown in FIG. 1 , the virtual heartbeat system 90 according to the embodiment of the present invention includes some or all of the virtual heartbeat device 100 and the user terminal device 110 , and further includes a sensor such as an electrocardiogram sensor. may include

Here, “including some or all” means that some components such as a sensor are omitted to configure the virtual heartbeat system 90 , or some or all of the components constituting the sensor are integrated into the virtual heartbeat device 100 . It is described as including all to help a sufficient understanding of the invention to mean things that can be configured and the like.

The virtual heartbeat device 100 corresponds to a device that is located near a user's heart and generates a virtual (or similar) heartbeat. For example, it is composed of a patch type attached to the skin and can be attached near the heart, and as will be discussed later, it is composed of a massage chair and the like to obtain the same operation and effect as a patch type device. The virtual heartbeat device 100 generates a virtual heartbeat when the user's heartbeat state is unstable, generates a virtual heartbeat, and causes the brain to mistake the vibration for a heartbeat, thereby reducing the heartbeat rate in an unstable state of mind and body. It stabilizes blood pressure and relieves stress. In this regard, a paper titled "Heart rate variability analysis using a virtual heartbeat oscillator" was published in the Journal of the Electrical Society of Electrical Engineers in 2016, and many studies related to virtual heartbeat technology can be found in the references of the paper.

In the virtual heart pacemaker 100, a user attaches a virtual heartbeat device 100 in the form of a patch consisting of a heartbeat sensor 101 and a heartbeat vibrator 103 generating a virtual heartbeat near the heart, and attaches the heartbeat sensor 101. It corresponds to a blood pressure stabilizing device that analyzes the detected heart rate and then gradually and slowly transmits the virtual atrial vibration from the heart rate vibrator 103 to the heart region to reduce the actual heart rate, stabilize blood pressure, and reduce stress. In order to stabilize blood pressure and reduce stress, the virtual heart rate device 100 monitors and analyzes the user's heart rate, which is not a method that requires will and effort, such as conventional deep breathing training or meditation, and then transmits an appropriate virtual heart rate vibration to gradually Reduces heart rate.

In other words, the virtual heart rate device 100 according to the embodiment of the present invention monitors the user's heart rate using an electrocardiogram sensor attached to the heart region, determines if the heart rate increases or the heart rate variability increases, and determines the virtual heart rate. It transmits the heartbeat vibration to the heart so that the brain recognizes the virtual heartbeat vibration as the actual heart rate to achieve blood pressure stabilization and stress reduction. In addition, such analysis and operation control are also possible in an application (hereinafter, an app) mounted on the user terminal device 110 such as a smartphone.

A technique for reducing blood pressure and relieving stress by virtual heartbeat will be described in more detail with reference to FIGS. 2A and 2B . For example, as seen in FIG. 2A , stress increases heart rate and blood pressure (see ① in FIG. 2A ). 2b (a) shows the state of the waveform as a waveform. Accordingly, the virtual heartbeat device 100 of FIG. 1 starts an operation by analyzing a heart rate variability (HRV) and automatically starting or manually operating. Here, the manual manipulation means that the virtual heartbeat can be controlled according to a user command of the user terminal device 110 as shown in FIG. 1 .

The virtual heartbeat device 100 is automatically or manually operated to transmit the virtual heartbeat vibration from the heartbeat vibrator 103 such as a vibrating speaker to the heart of the user (refer to ② in FIG. 2A ). Figure 2b (b) shows the signal waveform of the virtual heartbeat. As can be seen in the drawing, the virtual heartbeat intensity is stronger (or stronger) than the actual heartbeat intensity. Here, the actual heartbeat intensity may mean the heartbeat intensity when the user is in a normal state. Therefore, initially, a virtual heartbeat vibration with high intensity is generated through the heartbeat vibrator 103 . Thereafter, the virtual heartbeat is gradually and slowly (to the heart region) transmitted (see ③ in FIG. 2A ). Through this process, the sense of heterogeneity can be minimized and the brain can adapt. As a result, the brain gradually misunderstands the virtual heartbeat as an actual heartbeat (see ④ of FIG. 2A ). This leads to a decrease in the user's heart rate, which in turn stabilizes blood pressure and relieves stress. (c) of FIG. 2B is a graph showing a sham heartbeat that generates a spurious heartbeat with a high initial intensity (or large in terms of wave amplitude) and is gradually delivered slowly as the time t changes.

The user terminal device 110 may include a smart phone, a tablet PC, or a wearable device worn on the wrist. The user terminal device 110 may be loaded with an app for operating the virtual heartbeat device 100 according to an embodiment of the present invention, and may perform various operations according to the execution thereof. The user terminal device 110 typically analyzes and diagnoses data through a smartphone interworking function, and may perform automatic or manual operation control. Since only the heart rate vibrator 103 is mounted without a monitoring function, it may be utilized as a wearable healthcare device rather than a medical device. Since peripheral devices can be configured and interlocked in various forms, the embodiment of the present invention will not be particularly limited to a device such as a smartphone.

For example, the user terminal device 110 may communicate with the virtual heart pacemaker 100 located in the vicinity by executing the app, and accordingly, an electrocardiogram (EKG, ECG) measurement result from the virtual heart pacemaker 100 . It is possible to receive data such as, analyze the received data, and display the analysis result in the form of a graph on the screen. In this case, short-range wireless communication such as Bluetooth may be used for communication. For example, an app such as a smartphone may display a heart rate signal received through Bluetooth and a heart rate variability on the screen, and a control button may be displayed on the screen so that the user can manually control the heart rate frequency. Accordingly, when the user clicks the control button, a user command, that is, a control signal is transmitted to the virtual heartbeat device 100 , and thus a preset virtual heartbeat vibration may be generated.
