Description

Invisible bra with power measurement and wireless transmission

The invention relates to an invisible bra, in particular to an invisible bra with a heart-charging and wireless transmission function.

In order to facilitate the measurement of ECG signals, many cardiac power measuring devices have been developed to be miniaturized and easy to wear. Therefore, it is usually necessary to attach the electrodes to the chest part of the subject, and it is convenient for female subjects. At present, some manufacturers put the electrodes of the heart-charging device on general underwear, such as a general bra, and electrically connected to a host for recording ECG via a metal wire. When wearing underwear, the underwear is tight. The beam action enables the measurement electrodes to be attached to the chest surface for measurement of the electrocardiogram signal, but the manner in which the electrode and the metal wire are embedded in the underwear not only causes discomfort when the underwear is worn, It is also easy for the subject to sway or bend because of the body movement, which causes the electrode to be displaced or detached from the subject, thereby causing signal interruption or large noise, which is quite inconvenient to use.

Accordingly, it is an object of the present invention to provide an invisible bra that conveniently measures ECG signals and wirelessly transmits ECG signals.

Therefore, the invisible bra of the present invention has a bran body made of silicone rubber, and an electrode module respectively disposed on the bra body, a central processing module and a wireless transmission module. . The bra body includes two masks spaced apart from each other for being directly adhered to the left and right breast surfaces of the user, and each of the mask portions has a Adhered to the inner side of the user's body surface, and a side facing away from the inner side. The electrode module includes two sides spaced apart from the inner side surface of one of the mask portions, and the exposed surface of the electrode module is aligned with the inner side surface of the mask portion, and can be interlocked against the user body by the mask portion The electrode of the table. The central processing module is electrically connected to the electrodes and disposed in one of the mask portions, and can measure the ECG signal and output a detection result corresponding to the ECG signal via the electrodes. The wireless transmission module is disposed in a mask portion connected to the central processing module signal, and can wirelessly transmit the ECG signal and the detection result measured by the central processing module.

The effect of the invention is that the electrode module can be firmly attached to the chest of the subject by integrating the electrode module, the central processing module and the wireless transmission module on the bra body of the silicone material. The wireless transmission module can also be directly used to wirelessly transmit the measured signals and results to the remote monitoring system without having to configure a stack of wires on the subject.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

As shown in FIG. 1 to FIG. 3, a preferred embodiment of the invisible bra of the present invention has the advantages of measuring the ECG signal and can be used for measuring the ECG signal. The measured ECG information is wirelessly transmitted to a remote monitoring system 200, such as a medical institution.

The invisible bra 3 includes a bra body 31, and an electrode module 32, a central processing module 33 and a wireless device respectively mounted on the bra body 31. Transmission module 34.

The bran body 31 is made of silicone rubber and can be directly adhered to the surface of the user's breast 101, and includes two mask portions 311 spaced apart from each other, and a connecting portion 314 connected to opposite sides of the mask portions 311. Each of the mask portions 311 has an inner side surface 312 for attaching to the surface of the user's breast 101, and a side surface 313 opposite to the inner side surface 312. The electrode module 32 and the central processing module are respectively disposed. The wireless transmission module 33 and the wireless transmission module 34 are disposed on the mask portion 311 that is worn on the left breast 101.

The electrode module 32 includes two electrodes 321 which are exposed to the inner side surface 312 of one of the mask portions 311 at intervals, and the exposed surfaces of the electrodes 321 are aligned with the inner side surface of the mask portion 311 and adjacent to the mask. In the present embodiment, the electrodes 321 are dry electrodes, but in the implementation, the wet electrodes may be used instead, and are not limited thereto.

The central processing module 33 is integrated with the wireless transmission module 34 and embedded in the mask portion 311 where the electrodes 321 are disposed. The central processing module 33 is embedded in the mask portion via two strips. The wires 330 in 311 are electrically connected to the electrodes 321 through which the electrocardiogram signals can be measured. The central processing module 33 includes a variable gain differential amplifying unit 331 electrically connected to the wires 330, and a filtering unit 332 connected to the variable gain differential amplifying unit 331. A signal is connected to the filtering unit 332. The analog/digital conversion unit 333, and a signal are connected to the arithmetic unit 334 of the analog/digital conversion unit 333.

The variable gain differential amplifying unit 331 is composed of a variable gain differential amplifier based on an instrumentation amplifier, and amplifies the electrocardiogram by differential amplification. Signals to adjust the optimal gain parameters and eliminate common mode noise generated by other physiological signals (eg, EMG or breathing). However, since the human body is highly variable, for example, the fat ratio may seriously affect the amplitude of the output signal, the variable gain differential amplifying unit 331 can adjust the optimal gain parameter.

The filtering unit 332 is responsible for improving the signal to noise ratio (SNR) of the ECG signal. Since the ECG signal is composed of a signal of 0.5 to 100 Hz, the filtering unit 332 filters out the ECG signal by using the following filter. Other noise: (1) high-pass filter (filtering low-frequency signals below 0.5Hz), (2) low-pass filter (filtering out signals above 100Hz), and (3) 60Hz band rejection filter (filtering) 60Hz city electricity noise).

After the electrocardiographic signal is amplified and filtered, the analog/digital conversion unit 333 samples the analog ECG signal at a sampling frequency of two hundred hertz or more to obtain a digital ECG signal. The computing unit 334 has an ECG analysis program built therein, and the digital heart rate signal is detected, and the heart rate, premature atrial contraction (PAC), and early ventricular contraction (premature) are detected. Ventricular contraction, PVC), and heart rate variability, etc., and output a test result.

The computing unit 334 then encapsulates the data including the detection result and the ECG signal, and transmits the data to the wireless transmission module 34 in a serial transmission manner, and the wireless transmission module 34 is further configured by wireless communication, such as Bluetooth or radio frequency ( The radio frequency, RF module, etc., sends the ECG data to the remote monitoring system 200.

When the invisible bra 3 of the present invention is used, the bra body 31 can be directly used first. The wear is fixed to the chest 100 of the subject. Since the principle and the manner in which the bra body 31 can be directly attached and fixed to the user's breast 101 are conventional techniques, they will not be described in detail.

Since the electrodes 321 are adjacent to the left and right ends of the left side mask portion 311, respectively, when the bra body 31 is worn, the electrodes 321 are adjacent to the root portion of the left breast portion 101, and are closer to the heart (not shown). . After the bra body 31 is worn, the central processing module 33 can start measuring the ECG signal through the electrodes 321 , and then the wireless transmission module 34 wirelessly transmits the measured ECG signals and detection results to the remote end. The monitoring system 200 facilitates the remote monitoring system 200 to instantly determine whether the subject's ECG signal and cardiac function are abnormal, so as to achieve the purpose of remote medical care and medical care.

In this embodiment, the electrode module 32, the central processing module 33, and the wireless transmission module 34 are disposed on the same mask portion 311. However, the central processing module 33 and the wireless transmission module 34 may also be implemented. It is disposed on different mask portions 311.

In summary, the structural design of the bracing body 31 can be closely attached to the subject by integrating the electrode module 32, the central processing module 33 and the wireless transmission module 34 on the bra body 31. The function of the surface of the breast 101 enables the electrodes 321 embedded in the inner side surface 312 of the mask portion 311 to firmly adhere to the chest 100 of the subject without being displaced or disengaged due to shaking or bending of the subject's body. The body surface, and no need to wear other fixed electrode patches and the like, for the female subject, the invisible bra of the present invention can also be directly used as a commonly worn bra. In addition, The wireless transmission module 34 can be used to wirelessly transmit the measured signal to the remote monitoring system 200, and no need to configure a stack of wires on the subject, so the use is convenient. Therefore, the object of the present invention can be achieved.
