Description

Directional arm-type heartbeat measuring device

The present invention relates to a directional arm-type heartbeat measuring device, especially an electronic device suitable for monitoring the heartbeat of a user during exercise.

Traditional heartbeat measurement methods can be roughly divided into chest-worn and wrist-worn heartbeat measurement devices. The chest-worn heartbeat measurement device uses electrode patches and electrocardiography (Electrocardiography, ECG or EKG) principles, and It is worn on the chest of the user; and a wrist-worn heartbeat measurement device commonly uses a photoplethysmographic (PPG) element and is worn on the wrist, such as a smart bracelet or smart watch.

However, although the chest-worn heartbeat measuring device has accurate measurement, when worn for a long time, the user is likely to feel discomfort, especially women. On the other hand, in the case of vigorous exercise and sweating, sweat easily interferes with the electrode measurement, resulting in noise, and in many user experiences, sweat easily causes the device to fall off and the measurement fails.

In addition, traditional chest-worn heartbeat measurement devices mostly use low-frequency and low-power transmitters, which have less impact on human physiology, and therefore are generally welcomed by users. However, low-frequency and low-power transmitters are limited by the ability to transmit signals. If the transmission angle is slightly offset or exceeds the acceptable distance, it will not be able to effectively transmit signals to the receiver and is easily blocked by foreign objects. Break, which affects the signal's transmission capability, or interferes with other receivers. For example, the Republic of China new patent announcement number No. M344138, and Invention Patent Publication No. 201247170.

On the other hand, the traditional wrist-worn heartbeat measurement devices mostly use optical measurement, which is often easy to cause the device to loosen due to changes in the rotation of the wrist, which leads to the influence of external environmental light interference on the measurement results. In addition, because most sports are in motion, the wrist will swing greatly with the movement of the human body. Therefore, for the stability of signal transmission, a high-frequency transmitter is usually used, and the transmission frequency is as high as about 2.4GHz, so it can be Quickly and conveniently connect physiological information to a mobile phone or tablet computer, such as the Republic of China New Patent Announcement No. M310726 and M489622. However, the long-term high-frequency signal will cause adverse effects on the human body, especially those with heart disease, it is not recommended to wear it, because the heart rhythm regulator is easily interfered by these frequencies.

Furthermore, according to the relevant regulations of the Federal Communications Commission (FCC), when the transmission power is above 9KHz, it must pass the review of the committee before it can be listed. If the device's transmission power is below 9KHz, it does not need to go through official review . According to this, traditional wrist-worn heartbeat measurement devices all use Bluetooth communication modules, so they must pass the inspection of relevant units before going to market.

In fact, when performing short-distance transmission, such a high transmission power is not required. In addition to wasting energy, and long-term use, the high transmission power may also have some impact on the human body or other peripheral devices.

The main purpose of the present invention is to provide a directional arm-type heartbeat measurement device, which can take the arm muscle of the human arm as a measurement object, and is easy to wear and stable, and is not easy to fall off due to arm movement.

Another object of the present invention is to provide a directional arm heartbeat The measurement device can transmit the signal of the heartbeat measurement result in a low-frequency and low-power way to reduce the energy loss, and can also avoid some adverse effects on the human body or other peripheral equipment due to high transmission power.

In order to achieve the above object, the present invention provides a directional arm-type heartbeat measurement device, which is used to be worn on a user's arm. The device mainly includes a housing, an arm band, a heartbeat measurement module, and directivity Antenna and signal processing module.

According to this, the new model uses the arm muscle of the human arm as a measurement object, which is not only easy to wear and not easy to loosen, but according to biomechanical analysis and cantilever theory, it is close to the force application point, so the arm oscillates when it swings It has the least force and is less prone to vibration due to vibration. In addition, the new type uses a directional antenna to transmit low-frequency and low-power signals. In addition to reducing energy loss, it can also avoid some adverse effects on the human body or other peripheral devices due to high transmission power.

Furthermore, the directional antenna of the present invention can be assembled inside the housing and located at least one of the four side ends of the housing, or can be configured to form a longitudinal axis with at least one of the four side ends of the housing or The horizontal axis is at a specific angle, and the specific angle is between 0 degrees and 90 degrees. According to this, the directional antenna of the present invention can be installed on the side of the housing closest to the side of the receiving module, or the configuration angle of the directional antenna can be set according to the orientation of the receiving module, thereby improving the signal transmission quality.

In addition, the corresponding two side ends of the housing of the present invention may each include a solid The fixed loops, and the two ends of the arm bands can be coupled to the fixed loops respectively. Furthermore, the two ends of the arm-type belt of the present invention may include a reverse folding part, and the fixing rings may be sleeved on the reverse folding part.
