Referring to fig. 1, 2, 3 and 4, as shown in fig. 1, in a physiological signal collector 100 according to an embodiment of the present application, the physiological signal collector 100 is configured to be worn on skin of a user to be tested to obtain a bioelectric signal, and the signal collection host 230 is detachably mounted on the physiological signal collector 100 and configured to collect the bioelectric signal, where the bioelectric signal includes an electrocardiographic signal, an electromyographic signal, an electroencephalographic signal, an oculographic signal and the like. As in fig. 1.

The physiological signal collector 100 comprises a flexible substrate 110, a conductive layer 125 and a plurality of signal collecting electrodes 120 are arranged on the flexible substrate 110, the plurality of signal collecting electrodes 120 are used for collecting bioelectric signals of at least three different positions on the skin of a user to be tested, and the conductive layer 125 is used for conducting the bioelectric signals to a signal collecting host 230. The flexible substrate 110 is further provided with a connection layer 124, and the conductive layer 125 is electrically connected to the signal acquisition electrode 120 through the connection layer 124.

According to the embodiment of the application, the conductive layer 125 and the signal acquisition electrode 120 are respectively prepared on the flexible substrate 110 according to the conductive patterns, the conductive layer 125 and the signal acquisition electrode 120 are respectively lapped through the connecting layer 124 to realize conductive connection, and the outer contour of the flexible substrate 110 is cut along the conductive layer 125 and the signal acquisition electrode 120 according to the requirement, so that the outer contour of the physiological signal acquisition device 100 is formed. The connecting layer 124, the signal collecting electrode 120 and the conducting layer 125 form a series circuit, and in the strong current treatment scene of applying to defibrillation or high-voltage electric knife, the connecting layer 124 additionally arranged on the flexible substrate 110 can prevent defibrillation energy from being conducted and leaked through the signal collecting electrode 120 and the conducting layer 125, thereby affecting the treatment effect and not affecting the accuracy of bioelectric signals collected by the signal collecting electrode 120.

In one embodiment, the thickness of the connection layer 124 is 5 μm-200 μm and/or the resistance of the connection layer 124 is set to 1 k-50 k ohms to withstand the high current caused by the medical defibrillator or the electrostatic discharge, so as to prevent the signal collection host 230 from being destroyed by the high current. The embodiment provides that the connecting layer 124 made by using the printing process is light and thin, the product structure is compact, the thickness is not more than 200 μm, the connecting layer 124 is connected with the signal acquisition electrode 120 in series, the conducting layer 125 is not connected by other leads, the traditional defibrillation patch resistor which is necessary to be used in monitoring equipment due to equipment safety requirements can be replaced, the traditional patch resistor is overlarge in size, and needs to be connected by leads when in use, the use is heavy and cannot be used for compact physiological monitoring equipment application, and the product provided by the embodiment is light in size, miniaturized in structure and suitable for home remote monitoring. Particularly during defibrillation therapy, the patient needs to receive a plurality of defibrillation strong currents to restore heart function, and if the connection layer 124 is not provided, defibrillation energy enters the signal collecting main unit 230 through the signal collecting electrode 120 and the conductive layer 125, so that the signal collecting main unit 230 is destroyed by the strong current. The resistance value of the connection layer 124 provided in this embodiment is 1 k-50 k ohms, which can bear multiple strong current impact, and the signal collection host 230 can still be normally used after the end of the defibrillation treatment, so as to collect and record bioelectric signals, and enhance the use reliability of the device. If the resistance of the connection layer 124 is measured to be less than 1K ohm or more than 50K ohm, signal noise may be generated, affecting the accuracy of the bio-electrical signal acquisition.

The printing paste provided in this embodiment may be a resin paste.

In one embodiment, the connecting layer 124 is printed on the signal collecting electrode 120 and the conductive layer 125 by using a printing process, so that the wearing weight is not affected, the user to be tested can wear the device for a long time without interruption, and the bioelectric signals, especially the electrocardio signals, are monitored for a long time, so that the user to be tested can be helped to monitor the health or hidden trouble of the heart more comprehensively, and in a strong current treatment environment, such as defibrillation strong current or high voltage of an electric knife applied by the user to be tested is conducted to the signal collecting host 230 through the conductive layer 125, so that the host is damaged by the strong current. Therefore, the physiological signal collector 100 provided by the embodiment of the application is light in wearing, is convenient for the user to be tested to wear for a long time without interruption, and is safer and more reliable by considering the use requirement of a monitoring scene, and ensuring that the physiological signal collector 100 collects accurate bioelectric signals in real time.

The physiological signal collector 100 is worn on the skin of the user to be measured to obtain bioelectric signals, the signal collection host 230 is mounted on the physiological signal collector 100 to realize signal collection and storage recording, and the plurality of signal collection electrodes 120 collect bioelectric signals at least at three different positions and transmit the bioelectric signals to the signal collection host 230 through the conductive layer 125. The signal acquisition electrode 120 and the conductive layer 125 are electrically connected through the connecting layer 124, so that the connecting layer 124 can inhibit the influence of strong current on the bioelectric signals acquired by the physiological signal acquisition device 100 on the basis of meeting the requirement of accurately acquiring the bioelectric signals. In this embodiment, the conductive layer 125, the signal collecting electrode 120 and the connection layer 124 may be printed on the flexible substrate 110 by using a printing process, and the conductive layer 125 and the signal collecting electrode 120 are electrically connected through the connection layer 124, so as to construct a lighter wearable product.

The flexible substrate 110 may be a PET sheet that is more lightweight to use and easier to prepare the connection layer 124 and the conductive layer 125. The bioelectric signals collected by the signal collecting electrode 120 are conducted to the conducting layer 125 through the connecting layer 124, even if the bioelectric signals carrying strong current are conducted to the conducting layer 124, most of energy is inhibited by the connecting layer 124 and cannot be conducted to the signal collecting host 230 through the conducting layer 125, therefore, the signal collecting host 230 records physiological signals processed through the connecting layer 124, and through the arrangement of the connecting layer 124, defibrillation resistance devices are not required to be additionally introduced, the product space size of the physiological signal collector 100 is reduced under the condition of inhibiting energy leakage, the construction of the lighter physiological signal collector 100 is facilitated, and the application scene of products is enriched and expanded.

In this embodiment, the thickness of the connection layer 124 is adjusted and/or the resistance of the connection layer 124 is set to 1k to 50k ohms, specifically, the sheet resistance or the resistivity of the printing paste of the connection layer 124 can be adjusted to adjust the resistivity of the connection layer 124, or the thickness of the connection layer 124 is processed to 5 μm to 200 μm by a printing process to determine that the resistance of the connection layer 124 is set to 1k to 50k ohms, so as to bear the strong current caused by the medical defibrillator or the electrostatic discharge, and avoid the signal collecting host 230 from being destroyed by the strong current.

Particularly during defibrillation therapy, the patient needs to receive a plurality of defibrillation strong currents to restore heart function, and if the connection layer 124 is not provided, defibrillation energy enters the signal collecting main unit 230 through the signal collecting electrode 120 and the conductive layer 125, so that the signal collecting main unit 230 is destroyed by the strong current. The resistance value measured by the connection layer 124 provided in this embodiment is 1 k-50 k ohms, and can bear multiple strong current impact, and after the defibrillation treatment is finished, the signal collection host 230 can still be normally used to collect and record bioelectric signals, so that the use reliability of the device is enhanced. If the resistance of the connection layer 124 is measured to be less than 1K ohm or more than 50K ohm, signal noise may be generated, affecting the accuracy of the bio-electrical signal acquisition.
