Description

Technical Field

[0001] The present application relates to the field of signal monitoring, and in particular to a physiological signal monitoring device. Background Art

[0002] A heart rate belt is a common form of physiological signal monitoring device, which can be provided with two ECG electrodes, and the ECG signal is obtained by the potential difference of the potential at the location collected by the two ECG electrodes. However, since the contact between the heart rate belt and clothing will generate static electricity, the static electricity will affect the potential value collected by the two ECG electrodes, thereby affecting the accuracy of the acquired ECG signal. For example, when the amount of static electricity charge is too large, the signal-to-noise ratio of the ECG signal will be too small.

[0003] Therefore, it is hoped to provide a physiological signal monitoring device to achieve electrostatic shielding for ECG electrodes and improve the signal-to-noise ratio of ECG signals. Utility Model Content

[0004] One of the embodiments of the present specification provides a physiological signal monitoring device, the physiological signal monitoring device comprising: a strip, configured to be worn on the user's body, the strip comprising an inner surface and an outer surface; a plurality of electrodes, arranged on the inner surface of the strip, configured to receive electrical signals from the user's body, wherein one or more strands of conductive wire are arranged on the strip, the first part of the conductive wire is located on the outer surface or between the inner surface and the outer surface, so that each of the plurality of electrodes is at least partially located between the first part of the conductive wire and the user's body, the second part of the conductive wire extends to the inner surface and conducts the first part of the conductive wire with the user's body, and electrostatic shielding is achieved for the plurality of electrodes. By arranging one or more strands of conductive wire on the strip, the conductive wire forms a conductive area to conduct the charge on the outer surface of the strip into the human body, electrostatic shielding can be achieved for the electrode, and the strip can also retain its original elasticity and softness, thereby improving wearing comfort. In addition, the strip in this case has good elasticity and softness, so that the electrode can fit the human body more closely, thereby avoiding the signal instability problem caused by the electrode not fitting closely, thereby improving the quality of the electrocardiogram signal.

[0005] In some embodiments, the strip is at least woven from elastic threads, and the conductive threads are woven through the inner and outer surfaces of the strip. Weaving the strip with elastic threads can ensure that the strip has good elasticity and softness, thereby improving the wearing comfort of the user; weaving the conductive threads through the inner and outer surfaces of the strip can enable the conductive threads to form a conductive area on the outer surface to disperse static electricity, and introduce static electricity into the human body, thereby achieving electrostatic shielding of the electrode.

[0006] In some embodiments, the strip is formed by at least a mixed weaving of elastic wires and conductive wires. In the weaving method of the mixed weaving of elastic wires and conductive wires, the conductive wires are distributed in each layer of the strip (the weaving process makes the strip form a multi-layered structure when weaving), which is equivalent to increasing the number of conductive channels on the inner and outer surfaces, thereby better conducting static electricity on the outer surface into the human body and improving the stability of electrostatic shielding.

[0007] In some embodiments, at least part of the strip is formed by braiding conductive wires, and the conductive wires run through the inner surface and the outer surface in the thickness direction of the strip. In this way, the conductive wires can be woven at any position to connect the inner and outer surfaces of the strip, so that the partial area formed by the braiding of the conductive wires can be used as a conductive area as a whole, thereby better conducting the static electricity on the outer surface into the human body and improving the stability of electrostatic shielding.

[0008] In some embodiments, the first portion of the conductive wire and the second portion of the conductive wire both include a plurality of conductive paths arranged in parallel in the width direction of the strip. The conductive wire forms a plurality of conductive paths arranged in parallel in the width direction of the strip, and each of the plurality of conductive paths can conduct static electricity on the outer surface into the human body, thereby achieving electrostatic shielding of the electrode.

[0009] In some embodiments, each of the plurality of conductive channels is formed by bending and weaving the conductive wires into a wavy shape along the length direction of the strip. Weaving the conductive wires (or conductive channels) into a wavy shape can reserve stretching displacement for the conductive wires, ensuring that the wavy conductive channels formed by the conductive wires are stretchable in the length direction, making the conductive wires less likely to break when the strip is stretched, thereby ensuring that the strip as a whole has good elasticity and extensibility.

[0010] In some embodiments, the plurality of electrodes include two first electrodes and second electrodes spaced apart along the length direction of the strip, the first portion of the conductive line forms a first conductive region and a second conductive region insulated from each other, the first conductive region covers the outside of the first electrode and is insulated from the first electrode, and the second conductive region covers the outside of the second electrode and is insulated from the second electrode. The static electricity that has the greatest impact on the electrode is the static electricity on the outer surface facing the electrode and in its vicinity, and by setting the conductive region to cover the corresponding electrode, the conductive region can disperse the static electricity near the outer surface facing the electrode, thereby minimizing or eliminating the impact of the static electricity on the electrode.

[0011] In some embodiments, the first conductive region covers the first electrode in the length direction and the width direction of the strip, and the second conductive region covers the second electrode in both the length direction and the width direction of the strip. By setting the conductive region to cover the corresponding electrode in both the length direction and the width direction, the conductive region can better disperse the static electricity near the outer surface facing the electrode, thereby minimizing or eliminating the effect of the static electricity on the electrode.

[0012] In some embodiments, the plurality of electrodes include two first electrodes and second electrodes spaced apart along the length direction of the strip, and the first portion of the conductive line forms a conductive region, which covers the first electrode and the second electrode in both the length direction and the width direction. By connecting the two conductive regions to form one conductive region, the ability of the conductive region to disperse static electricity can be further enhanced, and by setting the conductive region to cover the two electrodes in both the length direction and the width direction, the effect of the static electricity on the electrodes can be reduced or eliminated to the greatest extent.

[0013] In some embodiments, multiple electrodes are attached to the strip through an insulating layer, and the insulating layer insulates the multiple electrodes from the conductive wires. By setting the insulation between the electrodes and the conductive wires, it can be ensured that the conductive wires will not affect the physiological signals collected by the electrodes from the user's body.

[0014] One of the embodiments of the present specification provides a physiological signal monitoring device, the physiological signal monitoring device comprising: a band configured to be worn on the user's body, the band comprising an inner surface and an outer surface; a plurality of signal electrodes arranged on the inner surface of the band, configured to receive electrical signals from the user's body; two groups of electrostatic protection sheets, one of the two groups of electrostatic protection sheets is arranged on the first area of ​​the outer surface of the band or between the inner surface and the first area of ​​the outer surface, and the other group of the two groups of electrostatic protection sheets is arranged on the second area of ​​the outer surface of the band or between the inner surface and the second area of ​​the outer surface, so that the plurality of signal electrodes are located between the electrostatic protection sheets and the user's body, wherein each group of electrostatic protection sheets includes a plurality of electrostatic protection sheets; a grounding electrode, located on the inner surface of the band, configured to conduct the electrostatic protection sheets with the user's body, and to achieve electrostatic shielding for the plurality of signal electrodes. By setting two groups of electrostatic protection sheets, each group of electrostatic protection sheets includes a plurality of electrostatic protection sheets, and the plurality of electrostatic protection sheets can achieve the effect of dispersing static electricity, while also ensuring that the band has good elasticity, thereby improving wearing comfort.

[0015] In some embodiments, at least some of the multiple electrostatic protection sheets are electrically connected by conductive wires. At least some of the multiple electrostatic protection sheets are electrically connected by conductive wires, so that the multiple electrostatic protection sheets can form a large conductive area, which is conducive to dispersing static electricity near the outer surface facing the signal electrode, thereby minimizing or eliminating the impact of the static electricity on the electrode.

[0016] In some embodiments, the distance between the connection points of two adjacent electrostatic protection sheets and the conductive wire is less than the natural length of the conductive wire. By setting the distance between the connection points of two adjacent electrostatic protection sheets and the conductive wire to be less than the natural length of the conductive wire, a length that can be stretched can be reserved for the conductive wire, thereby improving the stretchability of the conductive wire, and further improving the stretchability of the physiological signal monitoring device.

[0017] In some embodiments, the conductive wire is an elastic wire, and the conductive wire can be elastically stretched along the axial direction of the conductive wire. By setting the conductive wire as an elastic wire, the elasticity of the entire strip can be improved.

[0018] In some embodiments, the plurality of signal electrodes include a first signal electrode and a second signal electrode spaced apart along the length direction of the strip, the plurality of electrostatic protection sheets are electrically connected in sequence through conductive wires, and the plurality of electrostatic protection sheets form a conductive region, and the conductive region covers the first signal electrode and the second signal electrode in both the length direction and the width direction of the strip. Since the static electricity that has the greatest impact on the signal electrode is the static electricity on the outer surface facing the signal electrode and its vicinity, by providing a conductive region to cover the two signal electrodes, the conductive region can disperse the static electricity near the outer surface facing the signal electrode, thereby minimizing or eliminating the impact of the static electricity on the signal electrode.

[0019] In some embodiments, the plurality of signal electrodes include two first signal electrodes and a second signal electrode spaced apart along the length direction of the strip, a portion of the plurality of electrostatic protection sheets are electrically connected by conductive wires to form a first conductive region, the first conductive region covers the outside of the first signal electrode, another portion of the plurality of electrostatic protection sheets are electrically connected by conductive wires to form a second conductive region, the second conductive region covers the outside of the second signal electrode, and the first conductive region and the second conductive region are insulated from each other. By setting different conductive regions to cover corresponding electrodes, different conductive regions can disperse static electricity near the outer surface facing the electrode, thereby minimizing or eliminating the effect of the static electricity on the electrode.

[0020] In some embodiments, the first conductive region covers the first signal electrode in both the length and width directions of the strip, and the second conductive region covers the second signal electrode in both the length and width directions of the strip. By setting different conductive regions to cover corresponding signal electrodes in both the length and width directions of the strip, different conductive regions can disperse static electricity near the outer surface facing the signal electrode, thereby minimizing or eliminating the effect of the static electricity on the signal electrode.

[0021] In some embodiments, multiple electrostatic protection sheets are arranged in parallel along the length of the strip. In this way, the size or distribution density of the electrostatic protection sheets at different positions can be adjusted to take into account the elasticity of the strip and the electrostatic shielding effect of the electrostatic protection sheets on the signal electrode.

[0022] In some embodiments, the electrostatic protection sheets are stacked end-to-end to form a bent structure, and the bent structure can be elastically stretched along the length of the strip. In this arrangement, the connection stability between adjacent electrostatic protection sheets can be improved, while ensuring that the strip has good elasticity. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Figure 1 Schematic diagram of application scenarios of the physiological signal monitoring device according to some embodiments of this specification. Figure 1As shown, in some embodiments, an application scenario 100 of a physiological signal monitoring device (hereinafter referred to as application scenario 100) may include a terminal device 110, a network 120, a storage device 130, a monitoring object 140, and a physiological signal monitoring device 150. In some embodiments, each component in the application scenario 100 (e.g., terminal device 110, storage device 130, physiological signal monitoring device 150) may be connected and / or communicate with each other via the network 120 (e.g., wireless connection, wired connection, or a combination thereof).

[0054] The terminal device 110 refers to the device and / or software used by the user related to the application scenario 100. The users related to the application scenario 100 include, but are not limited to, the monitored object 140, doctors (e.g., clinicians, radiotherapists), nurses, etc. For example, the terminal device 110 may be a device or software for controlling the physiological signal monitoring device 150. The user issues a control instruction to the physiological signal monitoring device 150 through the terminal device 110, thereby controlling the physiological signal monitoring device 150 to collect the physiological signals of the monitored object 140. For example, the terminal device 110 may send the control instruction input by the user to the physiological signal monitoring device 150 through the network 120, so as to control the physiological signal monitoring device 150 to collect the physiological signals of the monitored object 140. In some embodiments, the terminal device 110 may obtain the physiological signals of the monitored object 140 collected by the physiological signal monitoring device 150 through the network 120. In some embodiments, the terminal device 110 may be one of or any combination of other devices having input and / or output functions, such as a mobile device, a tablet computer, a laptop computer, a desktop computer, etc.

[0055] Physiological signals refer to bioelectric signals (e.g., electrocardiographic signals, electromyographic signals, etc.) of an object (e.g., monitoring object 140) collected by a signal acquisition device (e.g., physiological signal monitoring device 150). Physiological signals can be mixed signals mixed with noise signals (e.g., motion artifact signals, static signals, etc.) and pure physiological signals. Among them, pure physiological signals refer to the real physiological signals of an object (e.g., monitoring object 140) obtained after filtering out the noise signals.

[0056] The network 120 can connect the various components of the application scenario 100 (for example, the terminal device 110, the storage device 130, the physiological signal monitoring device 150) and / or connect the application scenario 100 with external resources. The network 120 can enable the various components of the application scenario 100 to communicate with each other and with other parts outside the application scenario 100, and promote the exchange of data and / or information. For example, the terminal device 110 can obtain the physiological signals of the monitored object 140 collected by the physiological signal monitoring device 150 through the network 120. For another example, the storage device 130 can obtain the physiological signal data of the monitored object 140 collected by the physiological signal monitoring device 150 through the network 120 and store it.

[0057] In some embodiments, the network 120 may be any form of wired or wireless network, or any combination thereof. As an example only, the network 120 may include a cable network, a wired network, a fiber optic network, a telecommunications network, an intranet, the Internet, a local area network (LAN), a wide area network (WAN), a wireless local area network (WLAN), a metropolitan area network (MAN), a public switched telephone network (PSTN), a Bluetooth network, a ZigBee network, a near field communication (NFC) network, etc., or any combination thereof. In some embodiments, the network 120 may include at least one network access point, and at least one component of the application scenario 100 may be connected to the network 120 through the access point to exchange data and / or information. For example, data such as collected physiological signals may be transmitted through the network 120.

[0058] The storage device 130 may store data, instructions, and / or any other information. In some embodiments, the storage device 130 may store data obtained from the physiological signal monitoring device 150 and / or the terminal device 110. For example, the storage device 130 may store physiological signals collected by the physiological signal monitoring device 150. In some embodiments, the storage device 130 may include a large-capacity memory, a removable memory, a volatile read-write memory, a read-only memory (ROM), etc., or any combination thereof. Exemplary large-capacity memories may include magnetic disks, optical disks, solid-state disks, etc. In some embodiments, the storage device 130 may be implemented on a cloud platform. By way of example only, the cloud platform may include a private cloud, a public cloud, a hybrid cloud, a community cloud, a distributed cloud, an internal cloud, a multi-layer cloud, etc., or any combination thereof.

[0059] In some embodiments, the storage device 130 may be connected to the network 120 to communicate with at least one other component in the application scenario 100. At least one component in the application scenario 100 may access data, instructions, or other information stored in the storage device 130 through the network 120. In some embodiments, the storage device 130 may be directly connected or communicate with one or more components (e.g., the physiological signal monitoring device 150, the terminal device 110) in the application scenario 100. In some embodiments, the storage device 130 may be part of the physiological signal monitoring device 150 and / or the terminal device 110.

[0060] The monitoring object 140 refers to the monitoring object of the physiological signal monitoring device 150 , for example, the user of the physiological signal monitoring device 150 or a patient or experimenter who needs to collect physiological signals.

[0061] The physiological signal monitoring device 150 refers to a device for collecting or monitoring physiological signals of the monitored object 140. The physiological signal monitoring device 150 can be worn on at least one body part (for example, chest, back, waist, etc.) of the monitored object 140 to collect physiological signals of the monitored object 140. In some embodiments, the physiological signal monitoring device 150 can be a belt-like structure (for example, a heart rate belt), including a belt strip and a plurality of electrodes. The belt strip can be used to wear the physiological signal monitoring device 150 on at least one body part of the monitored object. The plurality of electrodes can be arranged on the inner surface of the belt strip, for fitting with at least one body part of the monitored object 140, so as to collect electrical signals of the monitored object 140 (for example, the electric potential at the location of the electrodes).

[0062] In some embodiments, the physiological signal monitoring device 150 may have an independent power supply. The physiological signal monitoring device 150 may send the collected data (e.g., physiological signals) to other components (e.g., storage device 130, terminal device 110) via wired or wireless (e.g., Bluetooth, WiFi, etc.). In some embodiments, one or more components on the application scenario 100 may be part of the physiological signal monitoring device 150. For example, the physiological signal monitoring device 150 may include a storage device 130, etc. For more information about the physiological signal monitoring device 150, see Figure 3A-3J and its related description.

[0063] In some embodiments, the application scenario 100 may further include a processing device ( Figure 1 (not shown in the figure, it can be configured in the physiological signal monitoring device 150 or the terminal device 110). The processing device can calculate and obtain physiological data based on the electrical signals collected by multiple electrodes. Physiological data refers to data determined based on physiological signals that reflect the bioelectric characteristics of the monitored object (for example, the monitored object 140). For example, when the physiological signal is an electrocardiogram signal, the physiological data can be electrocardiogram data.

[0064] It should be noted that the above description of the application scenario 100 is only for example and explanation, and does not limit the scope of application of this specification. For those skilled in the art, various modifications and changes can be made to the application scenario 100 under the guidance of this specification. However, these modifications and changes are still within the scope of this specification.

[0065] Figure 2A is a diagram of the inner surface structure of a conventional physiological signal monitoring device according to some embodiments of this specification; Figure 2B is a diagram of the outer surface structure of a conventional physiological signal monitoring device according to some embodiments of this specification. Figure 2A and Figure 2B As shown, a conventional physiological signal monitoring device 200 may include a strip 210 and a plurality of electrodes, wherein the plurality of electrodes include an electrode 221 , an electrode 222 , an electrode 223 , an electrode 224 , an electrode 225 , and an electrode 226 .

[0066] The strip 210 is the base structure of the traditional physiological signal monitoring device 200, and is configured to be worn on the body of a user (e.g., the monitored object 140) so that multiple electrodes can fit the user's body. The strip 210 includes an inner surface (the contact surface with the user's body) and an outer surface (the other side opposite to the inner surface, facing away from the human skin). Both ends of the strip 210 may be configured with connectors (e.g., connecting buckles, not shown in the figure). When the connectors at both ends are connected (e.g., buckled), the strip 210 can surround and fit the wearing part of the user (e.g., the monitored object 140) (e.g., surround and fit the user's chest or waist).

[0067] The material of the strip 210 may include plant fibers (eg, cotton fibers, linen fibers, etc.), animal fibers (eg, wool, etc.), synthetic fibers (eg, acrylic fibers, polyester, etc.), etc. For example, the strip 210 may be woven from plant fibers.

[0068] Electrode 221 and electrode 222 are electrodes for collecting electrical signals, and electrode 221 and electrode 222 are not connected. Figure 2A As shown, electrodes 221 and 222 may be disposed on the inner surface of strip 210 and fit against the body of the monitored subject (eg, monitored subject 140) to collect electrical signals (eg, electrical potential) at their locations.

[0069] The electrodes 221 and 222 may be connected to the connection ports 231 and 232, respectively. The connection ports 231 and 232 may be connected to a transmitter (not shown in the figure) (for example, in a snap-fit ​​connection), and the transmitter may send the electrical signals (for example, electrocardiographic potentials) collected by the electrodes 221 and 222 to a processing device to determine the physiological signals (for example, electrocardiographic signals) and / or physiological data (for example, electrocardiogram) of the monitored object (for example, the monitored object 140) based on the electrical signals.

[0070] Electrode 223 and electrode 224 are electrostatic receiving electrodes, and electrode 223 and electrode 224 are not conductive. Figure 2B As shown, electrodes 223 and 224 may be disposed on the outer surface of strip 210 to receive electrostatic charges outside the human body (e.g., electrostatic charges generated by friction between the human body and the clothes it wears). In some embodiments, electrodes 223 and 224 may cover electrodes 221 and 222, respectively, to receive external electrostatic charges of electrodes 221 and 222 as much as possible.

[0071] Electrode 225 and electrode 226 are electrostatic discharge electrodes. Electrode 225 and electrode 226 are not connected, electrode 225 and electrode 223 are connected, and electrode 226 and electrode 224 are connected. Figure 2A As shown, electrodes 225 and 226 can be arranged on the inner surface of strip 210 and fit against the body of the monitored object (e.g., monitored object 140), and are respectively used to introduce the electrostatic charges received by electrodes 223 and 224 into the body of the monitored object (e.g., monitored object 140) to reduce the influence of the electrostatic charges on the electrical signals collected by electrodes 221 and 222, thereby achieving electrostatic shielding and improving the signal quality of the physiological signals finally obtained.

[0072] The material of the electrodes 221 , 222 , 223 , 224 , 225 and 226 may be non-elastic conductive rubber or the like.

[0073] However, the conventional physiological signal monitoring device 200 of the above structure has at least the following problems:

[0074] In order to make the electrodes 223 and 224 cover the electrodes 221 and 222 respectively, and the materials of the electrodes 223 and 224 are non-elastic rubber, the non-elastic area of ​​the traditional physiological signal monitoring device 200 is large, which makes the overall elasticity, adjustability, and breathability of the traditional physiological signal monitoring device 200 worse, which may cause discomfort or even skin damage to the user (for example, the monitored object 140) when wearing it, affecting the user's wearing experience. The deterioration of the elasticity of the traditional physiological signal monitoring device 200 also makes the traditional physiological signal monitoring device 200 worse in its fit with the human body, resulting in a low signal-to-noise ratio of the collected physiological signals.

[0075] The electrodes 223 and 224 are located on the outer surface of the strip 210 , which makes the manufacturing process of the traditional physiological signal monitoring device 200 more complicated than that of the physiological signal monitoring device without an anti-static structure, thereby increasing the defect rate of the traditional physiological signal monitoring device 200 during production.

[0076] The presence of electrodes 225 and 226 increases the overall length of the traditional physiological signal monitoring device 200, so that the connectors on both sides of the strap 210 move backward when the user wears it (for example, the connectors originally located at the side waist move to the back of the waist when worn), which increases the difficulty for the user to connect the connectors and affects the user experience.

[0077] Based on this, a physiological signal monitoring device (for example, physiological signal monitoring device 300, physiological signal monitoring device 400) is provided in the embodiments of this specification, which achieves an anti-static effect while ensuring the user experience and improves the signal-to-noise ratio of the electrocardiogram signals collected in static electricity scenarios.

Figure 3C , Figure 3D This is a front view of the physiological signal monitoring device when it is placed flat on a table or the ground (for example, when the outer surface or the inner surface is placed parallel to the table / ground).

[0079] In some embodiments, Figure 3A to Figure 3D As shown in , the physiological signal monitoring device 300 may include a strip 310 and a plurality of electrodes 320. Among them, one or more conductive wires 330 (for example, a first conductive wire 331, a second conductive wire 332, a third conductive wire 333, etc.) are arranged on the strip 310. The first portion 340 of the conductive wire 330 is located on the outer surface of the strip 310, or between the inner surface and the outer surface of the strip 310, and the second portion 350 (including the left second portion 351 and the right second portion 352) extends to the inner surface of the strip 310, and connects the first portion 340 of the one or more conductive wires 330 to the user's body to achieve electrostatic shielding for the plurality of electrodes 320.

[0080] The inner surface of the strip 310 is the side in contact with the user's body (eg, the side in contact with the user's skin), and the outer surface is the other side opposite to the inner surface (ie, the side facing away from the human skin).

[0081] The band 310 is a base structure of the physiological signal monitoring device, and is configured to be worn on the body of a user (e.g., the monitoring object 140) so that the plurality of electrodes can fit the user's body. For example, the two ends of the band 310 may be configured with connecting buckles, and when the connecting buckles at the two ends are buckled, the band 310 can surround and fit the wearing part of the monitoring object 140 (e.g., surround and fit the user's chest or waist).

[0082] The material of the strip 310 may include plant fibers (eg, cotton fibers, linen fibers, etc.), animal fibers (eg, wool, etc.), synthetic fibers (eg, acrylic fibers, polyester, etc.), etc. For example, the strip 310 may be woven from cotton fibers.

[0083] In some embodiments, the conductive wire may include metal fibers, carbon fibers, compound fibers, or polymer fibers.

[0084] In some embodiments, the strip 310 is formed by weaving at least an elastic thread (eg, cotton thread), and the conductive thread 330 (eg, silver fiber thread) is woven and woven on the inner surface and the outer surface of the strip 310. Figure 3A and Figure 3B As shown, the strip 310 may include an elastic portion 360 (white portion in the figure) composed of elastic threads and a plurality of conductive threads 330 (black portion in the figure, including a first conductive thread 331, a second conductive thread 332, and a third conductive thread 333).

[0085] In some embodiments, Figure 3C As shown, the conductive wire 330 includes multiple strands of conductive wire (for example, the first conductive wire 331, the second conductive wire 332, and the third conductive wire 333) which can be respectively woven on the inner surface and the outer surface of the strip 310 to form a first part 340 and a second part 350 of the conductive wire 330. The first part 340 includes the portion of the conductive wire 330 located on the outer surface of the strip 310 and the portion located between the outer surface and the inner surface of the strip 310 (for example, the first conductive wire 331, the second conductive wire 332, and the third conductive wire 333 are located on the outer surface of the strip 310 and the portion located between the outer surface and the inner surface of the strip 310), and the second part 350 includes the portion located on the inner surface of the strip 310 (for example, the first conductive wire 331, the second conductive wire 332, and the third conductive wire 333 are located on the inner surface of the strip 310); the portion of the conductive wire 330 located between the inner surface and the outer surface of the strip 310 is called a first inner conductive wire, for example, Figure 3CThe first internal conductive line 334 in the conductive line 330. The internal conductive line portion of the conductive line 330 (eg, the first internal conductive line 334) can conduct the portion of the conductive line 330 located on the inner surface of the strip 310 with the portion located on the outer surface of the strip 310 to achieve electrostatic shielding.

[0086] In order to realize the structure of the physiological signal monitoring device 300 described in the above embodiment, the weaving process of the physiological signal monitoring device 300 can be: first, the strip 310 is formed by weaving based on the elastic line, and then each of the multiple conductive wires included in the conductive wire 330 (for example, the first conductive wire 331, the second conductive wire 332 and the third conductive wire 333) is respectively shuttle-woven on the inner surface and the outer surface of the strip.

[0087] The specific process of the above shuttle weaving may include: parallel weaving of multiple strands of conductive wires included in the conductive wire 330. For example, the first conductive wire 331, the second conductive wire 332 and the third conductive wire 333 are shuttle-woven along the length direction of the strip 310 with a certain spacing (equal spacing or unequal spacing) in the width direction of the strip 310 (the length of each strand of conductive wire used is sufficient to be woven from beginning to end in the length direction of the strip 310), thereby obtaining the conductive wire 330 (including three strands of conductive wires arranged in parallel at intervals in the width direction of the strip 310, that is, the first conductive wire 331, the second conductive wire 332 and the third conductive wire 333 arranged in parallel at intervals in the width direction of the strip 310).

[0088] Electrostatic shielding refers to a state in which the electrodes of a physiological signal monitoring device are not affected by external charges or electric fields (e.g., electrostatic electric fields). Figure 3C The structure of the physiological signal monitoring device 300 shown is that when static electricity exists on the outer surface of the strip 310, the static electricity can enter the human body in sequence through the first part 340 of the conductive wire 330 (the part located on the outer surface of the strip 310 (for example, the part of the first conductive wire 331 located on the outer surface of the strip 310), the first internal conductive wire 334), and the second part 350 (the part of the conductive wire 330 located on the inner surface of the strip 310 (for example, the part of the first conductive wire 331 located on the inner surface of the strip 310)), so that the static electricity cannot affect the electrode 320.

[0089] In some embodiments of the present specification, elastic threads are used to weave straps, which can ensure that the straps have good elasticity and softness, thereby improving the wearing comfort of the user; conductive threads are weaved through the inner and outer surfaces of the straps, so that the conductive threads can form a conductive area on the outer surface to disperse static electricity, and introduce static electricity into the human body, thereby achieving electrostatic shielding of the electrode.

[0090] In some embodiments, the strip 310 may be formed by mixing and weaving at least elastic thread and conductive thread. Mixed weaving refers to the process of mixing conductive wire into elastic thread in a certain ratio (e.g., 1:5, 2:3, etc.) to form an integral whole and weaving the strip.

[0091] like Figure 3D As shown, based on the mixed weaving method of the above-mentioned strip 310, the multiple strands of conductive wire 330 (for example, the first conductive wire 331, the second conductive wire 332 and the third conductive wire 333) may include a first part 340 and a second part 350, wherein the first part 340 includes the portion of the conductive wire 330 located on the outer surface of the strip 310 and the portion located between the outer surface and the inner surface of the strip 310 (for example, including the first conductive wire 331, the second conductive wire 332 and the third conductive wire 333 located on the outer surface of the strip 310 and the portion located between the outer surface and the inner surface of the strip 310), and the second part 350 includes the portion located on the inner surface of the strip 310 (for example, including the first conductive wire 331, the second conductive wire 332 and the third conductive wire 333 located on the inner surface of the strip 310); the portion of the conductive wire 330 located between the inner surface and the outer surface of the strip 310 is called a second inner conductive wire, for example, Figure 3D The inner conductive wire (e.g., the second inner conductive wire 335) portion of the conductive wire 330 can conduct the portion of the conductive wire 330 located on the inner surface of the strip 310 with the portion located on the outer surface of the strip 310 (each inner conductive wire corresponds to a conduction channel, and each conduction channel can independently conduct the portion of the conductive wire 330 located on the inner surface of the strip 310 with the portion located on the outer surface of the strip 310) to achieve electrostatic shielding.

[0092] In some embodiments of the present specification, when there are fewer conductive channels, the breakage of the conductive wires at the conductive channels may affect the electrostatic shielding effect. However, in the weaving method in which elastic wires and conductive wires are mixed, since the conductive wires are distributed in each layer of the strip (the weaving process allows the strips to form a multi-layered structure during weaving), it is equivalent to increasing the number of conductive channels on the inner and outer surfaces, thereby better conducting static electricity on the outer surface into the human body and improving the stability of the electrostatic shielding.

[0093] In some embodiments, at least part of the strip 310 can be formed by weaving conductive wires, and the conductive wires penetrate the inner and outer surfaces of the strip 310 in the thickness direction of the strip 310. In some embodiments, a certain area of ​​the strip 310 (for example, the area outside the position of the strip 310 where the electrode 320 is located) can be formed by weaving conductive wires. In this way, the conductive wires can conduct the inner and outer surfaces of the strip 310 at any position of the partial area, so that the partial area formed by weaving conductive wires can be used as a conductive area as a whole, thereby better introducing static electricity on the outer surface into the human body and improving the stability of electrostatic shielding. In some embodiments, the partial area formed by weaving conductive wires can also be elastic. As an example, an elastic wire with good elasticity can be prepared, and the conductive wire is wound around the outer peripheral side of the elastic wire (similar to the winding method of a spring), thereby obtaining a conductive wire with elasticity, and then the conductive wire with elasticity is woven to form at least a part of the area of ​​the strip 310. In some embodiments, the elastic conductive wire obtained in the above manner can also be woven to form the strip 310.

[0094] In some embodiments, the conductive wire may not connect the inner and outer surfaces of the strip. For example, the conductive wire is only woven on the outer surface of the strip and does not extend to the inner surface. In this case, the conductive wire only forms a conductive area on the outer surface to disperse static electricity.

[0095] In some embodiments, the physiological signal monitoring device 300 includes a plurality of electrodes 320 disposed on the inner surface of the strip 310 and configured to receive electrical signals from the user's body.

[0096] For example, Figure 3A and Figure 3B As shown, a plurality of electrodes 320 are arranged on the inner surface of the strip 310 and are configured to receive electrical signals (eg, electrocardiogram signals) from the user's body. Figure 3C or Figure 3D As shown, the first portion 340 of the conductive wire 330 arranged on the strip 310 is located between the outer surface or the inner surface and the outer surface, so that each electrode of the plurality of electrodes 320 (e.g., the first electrode 321, the second electrode 322) is at least partially located between the first portion 340 of the conductive wire 330 and the user's body, as shown in FIG. Figure 3A As shown, the second portion 350 of the conductive wire 330 extends to the inner surface and connects the first portion 340 of the conductive wire 330 to the user's body, thereby achieving electrostatic shielding for the plurality of electrodes 320 (eg, the first electrode 321 and the second electrode 322).

[0097] The plurality of electrodes are electrodes for collecting physiological signals (eg, electrocardiogram signals). The material of the electrodes may be a conductive material with relatively low hardness, such as conductive rubber, conductive silicone, and the like.

[0098] In some embodiments, the plurality of electrodes 320 are attached to the strip 310 via an insulating layer, and the insulating layer implements insulation between the plurality of electrodes 320 and the conductive wire 330. Figure 3A As shown, an insulating layer 370 may be disposed between the plurality of electrodes 320 and the strip 310 to insulate the plurality of electrodes 320 from the strip 310 (including the conductive wires 330 in the strip 310). The insulating layer may be made of any reasonable insulating material, such as insulating rubber.

[0099] In some embodiments, a plurality of holes may be dug on the strip 310, and each of the plurality of electrodes 320 may be respectively arranged in the aforementioned plurality of holes. An insulating material may be filled between each of the plurality of electrodes 320 and the inner wall of the hole to insulate the plurality of electrodes from the strip (including the conductive wires in the strip). In some embodiments, the conductive wire may not be woven on the electrode 320 and a certain area near it (that is, the conductive wire shuttles and weaves in the area outside the electrode 320), so as to achieve insulation between the electrode 320 and the strip 310. At this time, the electrode 320 may be directly attached to the strip 310. In some embodiments, the conductive wire of the electrode 320 at the location of the strip 310 may be covered with an insulating material, and the insulating material achieves insulation between the electrode 320 and the strip 310. For example, the strip may be woven with bare conductive wires first, and then the conductive wires in the strip area where the electrode 320 is located may be post-processed (insulated) to achieve insulation. For another example, a conductive wire with a surface covered with an insulating material may be used to weave a strip, and then the conductive wire outside the strip area where the electrode 320 is located may be post-processed (de-insulated) to remove the insulating material.

[0100] In some embodiments of the present specification, the insulation between the electrodes and the conductive wires can ensure that the conductive wires will not affect the physiological signals collected by the electrodes from the user's body.

[0101] In some embodiments, the physiological signal monitoring device 300 may be further configured with a plurality of connection ports on the outer surface of the band, and each of the plurality of connection ports may be respectively connected to each of the plurality of electrodes. The plurality of connection ports may be connected to a transmitter (e.g., in a snap-on manner), and the transmitter may send the electrical signals (e.g., ECG potentials) collected by the plurality of electrodes to a processing device, and the processing device may determine the physiological signals (e.g., ECG signals) and / or physiological data (e.g., ECG) of the monitored subject (e.g., monitored subject 140) based on the electrical signals.

[0102] For example, Figure 3BAs shown, the physiological signal monitoring device 300 may also be configured with a connection port 323 and a connection port 324 on the outer surface of the strip 310, and the first electrode 321 and the second electrode 322 may be respectively connected to the connection port 323 and the connection port 324. The connection port 323 and the connection port 324 may be connected to a transmitter (not shown in the figure) (for example, in a snap-fit ​​connection), and the transmitter may send the electrical signal (for example, electrocardiographic potential) collected by the first electrode 321 and the second electrode 322 to a processing device to determine the physiological signal (for example, electrocardiographic signal) and / or physiological data (for example, electrocardiogram) of the monitored object (for example, the monitored object 140) based on the above electrical signal.

[0103] In some embodiments, the first portion of the conductive line and the second portion of the conductive line each include a plurality of conductive paths arranged in parallel in a width direction of the strip.

[0104] A conductive channel refers to a channel through which electric charges (e.g., electrostatic charges) can flow. For example, each conductive wire in the strip can form a corresponding conductive channel. The number of conductive channels can be preset by the designer or manufacturer of the physiological signal monitoring device, and when the physiological signal monitoring device is produced, the above number of conductive wires are woven into its strip to obtain the above number of conductive channels. Exemplarily, the number of conductive channels can be 3, 4, or 5, etc.

[0105] For example, Figure 3A and Figure 3B As shown, the first part 340 and the second part 350 of the conductive wire 330 both include three conductive wires arranged in parallel in the width direction of the strip 310: a first conductive wire 331, a second conductive wire 332, and a third conductive wire 333. The first conductive wire 331, the second conductive wire 332, and the third conductive wire 333 respectively correspond to a conductive channel. Based on this, the first part 340 and the second part 350 of the conductive wire 330 both include three conductive channels arranged in parallel in the width direction of the strip 310.

[0106] In some embodiments of the present specification, the conductive wire forms a plurality of conductive channels arranged in parallel in the width direction of the strip, and each of the plurality of conductive channels can conduct static electricity on the outer surface into the human body, thereby achieving electrostatic shielding of the electrode.

[0107] Figure 3E is another structural diagram of the inner surface of the physiological signal monitoring device shown in some embodiments of this specification; Figure 3F is another structural diagram of the outer surface of the physiological signal monitoring device shown in some embodiments of this specification.

[0108] In some embodiments, each of the plurality of conductive channels is formed by bending and weaving a conductive line into a wavy shape along the length direction of the strip.

[0109] like Figure 3E and Figure 3F As shown, each conductive wire 330 in the strip 310 (for example, the first conductive wire 331, the second conductive wire 332, and the third conductive wire 333) is bent and woven into a wave shape along the length direction of the strip 310. Based on this, the conductive channels corresponding to the above conductive wires 330 are bent into a wave shape along the length direction of the strip 310.

[0110] In some embodiments, the shape of each of the multiple conductive channels in the length direction of the strip may also be a Z-shaped line, a right-angle wavy line, etc., which is not limited here.

[0111] In some embodiments of the present specification, the conductive wires (or conductive channels) are woven into a wavy shape, which can reserve stretching displacement for the conductive wires, ensuring that the wavy conductive channels formed by the conductive wires are stretchable in the length direction, making the conductive wires less likely to break when the strip is stretched, thereby ensuring that the strip as a whole has good elasticity and extensibility.

[0112] In some embodiments, Figure 3A As shown, the plurality of electrodes 320 include two first electrodes 321 and second electrodes 322 spaced apart and distributed along the length direction of the strip 310. In some embodiments, as Figure 3B As shown, the first portion 340 of the conductive line 330 forms a first conductive region 341 and a second conductive region 342 that are insulated from each other, the first conductive region 341 covers the outside of the first electrode 321 and is insulated from the first electrode 321, and the second conductive region 342 covers the outside of the second electrode 322 and is insulated from the second electrode 322.

[0113] Coverage means that the projection area of ​​the electrode is contained within the projection area of ​​the corresponding conductive area. The projection area refers to the area corresponding to the projection of the conductive area or the electrode in the thickness direction of the strip.

[0114] In some embodiments, the first conductive region covers the first electrode in the length direction of the strip, and the second conductive region covers the second electrode in the length direction of the strip.

[0115] Figure 3G It is a front view projection schematic diagram of a physiological signal monitoring device according to some embodiments of the present specification.

[0116] For example, Figure 3GAs shown, the projected long side 321-1 of the first electrode 321 (the side of the projection area of ​​the first electrode 321 that is parallel to the length direction of the strip 310) is contained in the projected long side 341-1 of the first conductive region 341 (the side of the projection area of ​​the first conductive region 341 that is parallel to the length direction of the strip 310), and the projected long side 322-1 of the second electrode 322 (the side of the projection area of ​​the second electrode 322 that is parallel to the length direction of the strip 310) is contained in the projected long side 342-1 of the second conductive region 342 (the side of the projection area of ​​the second conductive region 342 that is parallel to the length direction of the strip 310), so that the first conductive region 341 covers the first electrode 321 in the length direction of the strip 310, and the second conductive region 342 covers the second electrode 322 in the length direction of the strip 310. Taking the example that the projected long side 321-1 of the first electrode 321 is included in the projected long side 341-1 of the first conductive region 341, the inclusion means that the length of the projected long side 321-1 of the first electrode 321 is not greater than the length of the projected long side 341-1 of the first conductive region 341, and the projected long side 321-1 of the first electrode 321 is spatially located within the projected long side 341-1 of the first conductive region 341. The inclusion relationship described below is the same.

[0117] In some embodiments of the present specification, by providing a conductive region to cover the corresponding electrode in the length direction, the conductive region can disperse static electricity near the outer surface facing the electrode, thereby minimizing or eliminating the effect of the static electricity on the electrode.

[0118] In some embodiments, the first conductive region covers the first electrode in the width direction of the strip, and the second conductive region covers the second electrode in the width direction of the strip 310 .

[0119] Figure 3H is a schematic diagram of a side projection of a physiological signal monitoring device according to some embodiments of this specification. Figure 3H The left and right figures in the figure are schematic side projection diagrams when observing from two opposite sides of the physiological signal monitoring device 300.

[0120] For example, Figure 3HAs shown, the projected wide side 321-2 of the first electrode 321 (the side of the projection area of ​​the first electrode 321 that is parallel to the width direction of the strip 310) is contained in the projected wide side 341-2 of the first conductive region 341 (the side of the projection area of ​​the first conductive region 341 that is parallel to the width direction of the strip 310), and the projected wide side 322-2 of the second electrode 322 (the side of the projection area of ​​the second electrode 322 that is parallel to the width direction of the strip 310) is contained in the projected wide side 342-2 of the second conductive region 342 (the side of the projection area of ​​the second conductive region 342 that is parallel to the width direction of the strip 310), so that the first conductive region 341 covers the first electrode 321 in the width direction of the strip 310, and the second conductive region 342 covers the second electrode 322 in the width direction of the strip 310.

[0121] In some embodiments of the present specification, by providing a conductive region to cover the corresponding electrode in the width direction, the conductive region can disperse static electricity near the outer surface facing the electrode, thereby minimizing or eliminating the effect of the static electricity on the electrode.

[0122] In some embodiments of the present specification, the static electricity that has the greatest impact on the electrode is the static electricity on the outer surface directly facing the electrode and in its vicinity. By providing a conductive area to cover the corresponding electrode, the conductive area can disperse the static electricity near the outer surface directly facing the electrode, thereby minimizing or eliminating the impact of the static electricity on the electrode.

[0123] In some embodiments, the first portion 340 of the conductive line 330 may form a conductive region that covers the first electrode 321 and the second electrode 322 in the length direction of the strip. Figure 3B The first conductive region 341 corresponding to the first part 340 of the conductive line 330 can be connected to the second conductive region 342 to form a conductive region corresponding to the first part 340 , which covers the first electrode 321 and the second electrode 322 in the length direction of the strip 310 .

[0124] In some embodiments, the conductive region corresponding to the first portion of the conductive line covers the first electrode and the second electrode in the length direction.

[0125] Fig. 3I It is another front view projection schematic diagram of the physiological signal monitoring device shown in some embodiments of this specification.

[0126] For example, Fig. 3IAs shown, the projected long side 321-1 of the first electrode 321 and the projected long side 322-1 of the second electrode 322 are both contained within the projected long side 340-1 of the first part 340 of the conductive line 330 (the side of the projection area of ​​the first part 340 that is parallel to the length direction of the strip 310), so that the conductive area corresponding to the first part 340 of the conductive line 330 covers the first electrode 321 and the second electrode 322 in the length direction of the strip 310.

[0127] In some embodiments, the one conductive region formed by the first portion 340 of the conductive line 330 covers the first electrode and the second electrode in the width direction of the strip.

[0128] Figure 3J is another side projection schematic diagram of a physiological signal monitoring device according to some embodiments of this specification. Figure 3J The left and right figures in the figure are schematic side projection diagrams when observing from two opposite sides of the physiological signal monitoring device 300.

[0129] For example, Figure 3J As shown, the projected wide side 321-2 of the first electrode 321 and the projected wide side 322-2 of the second electrode 322 are both contained within the projected wide side 340-2 of the first part 340 of the conductive line 330 (the side of the projection area of ​​the first part 340 that is parallel to the width direction of the strip 310), so that the conductive area covers the first electrode 321 and the second electrode 322 in the width direction of the strip 310.

[0130] In some embodiments of the present specification, by setting a conductive area to cover the two electrodes in the width direction, the conductive area can be able to absorb static electricity near the outer surfaces facing the two electrodes, thereby minimizing or eliminating the effect of the static electricity on the electrodes.

[0131] In some embodiments of the present specification, the ability of the conductive region to disperse static electricity can be further enhanced by connecting two conductive regions to form one conductive region, and the effect of static electricity on the electrodes can be minimized or eliminated by setting the conductive region to cover the two electrodes in the length direction.

[0132] It should be noted that since the second part of the conductive wire connects the first part of the conductive wire to the user's body, when the two conductive areas are connected to form a conductive area, a loop may be formed between the conductive wire and the user's body, which may affect the potential difference on both sides of the body, thereby affecting the physiological signals collected by the first electrode and / or the second electrode from the user's body.

[0133] Figure 4A is a diagram of the inner surface structure of another physiological signal monitoring device according to some embodiments of this specification; Figure 4B is a structural diagram of the outer surface of another physiological signal monitoring device according to some embodiments of this specification; Figure 4C is another structural diagram of the outer surface of another physiological signal monitoring device shown in some embodiments of this specification.

[0134] In some embodiments, Figure 4A and 4B As shown, the physiological signal monitoring device 400 may include a strip 410 , a plurality of signal electrodes 420 , two sets of electrostatic protection sheets 440 , and a ground electrode 450 .

[0135] Similar to the strip 210 or the strip 310, the strip 410 is the base structure of the physiological signal monitoring device 400, and is configured to be worn on the body of a user (e.g., the monitoring object 140) so that the plurality of electrodes can fit the user's body. For example, the two ends of the strip 410 may be configured with connecting buckles, and when the connecting buckles at the two ends are buckled, the strip 410 can surround and fit the wearing part of the monitoring object 140 (e.g., surround and fit the user's chest).

[0136] Similar to the strip 310 , the material of the strip 410 may include plant fibers (eg, cotton fibers, hemp fibers, etc.), animal fibers (eg, wool, etc.), synthetic fibers (eg, acrylic fibers, polyester, etc.), etc. For example, the strip may be woven from cotton fibers.

[0137] A plurality of signal electrodes are arranged on the inner surface of the strip and are configured to receive electrical signals (e.g., electrocardiogram signals) from the user's body. The signal electrodes may be made of a conductive material with a relatively low hardness, such as conductive rubber, conductive silicone, etc. There is no conduction between the plurality of signal electrodes. For example, Figure 4A As shown, a plurality of signal electrodes 420 are arranged on the inner surface of the strip 410 and are configured to receive electrical signals (eg, electrocardiogram signals) from the user's body.

[0138] In some embodiments, the physiological signal monitoring device may be further configured with a plurality of connection ports on the outer surface of the band, and each of the plurality of connection ports may be respectively connected to each of the plurality of signal electrodes. The plurality of connection ports may be connected to a transmitter (e.g., in a snap-on manner), and the transmitter may send the electrical signals (e.g., ECG potentials) collected by the plurality of electrodes to a processing device, and the processing device may determine the physiological signals (e.g., ECG signals) and / or physiological data (e.g., ECG) of the monitored subject (e.g., monitored subject 140) based on the electrical signals.

[0139] For example, Figure 4BAs shown, the physiological signal monitoring device 400 may also be configured with a connection port 431 and a connection port 432 on the outer surface of the strip 410. The first signal electrode 421 and the second signal electrode 422 included in the multiple signal electrodes 420 may be respectively connected to the connection port 431 and the connection port 432. The connection port 431 and the connection port 432 may be connected to a transmitter (not shown in the figure) (for example, connected in a male and female snap manner). The transmitter may send the electrical signals (for example, electrocardiographic potentials) collected by the first signal electrode 421 and the second signal electrode 422 to a processing device to determine the physiological signals (for example, electrocardiographic signals) and / or physiological data (for example, electrocardiogram) of the monitored object (for example, the monitored object 140) based on the above electrical signals.

[0140] Two groups of electrostatic protection sheets can be arranged on the outer surface of the strip 410, or between the inner surface and the outer surface, so that the multiple signal electrodes 420 are located between the electrostatic protection sheets and the body of the user (e.g., the monitored object 140). In some embodiments, the first group of electrostatic protection sheets in the two groups of electrostatic protection sheets can be arranged in a first area of ​​the outer surface of the strip 410, or between the inner surface and the first area of ​​the outer surface; the second group of electrostatic protection sheets is arranged in a second area of ​​the outer surface of the strip 410, or between the inner surface and the second area of ​​the outer surface. The first area of ​​the outer surface refers to the left area on the strip, for example, the area between the first end 411 of the strip 410 and the connection port 431. The second area of ​​the outer surface refers to the right area on the strip, for example, the area between the second end 412 of the strip 410 and the connection port 432. The first group of electrostatic protection sheets includes a plurality of electrostatic protection sheets. The second group of electrostatic protection sheets includes a plurality of electrostatic protection sheets. Exemplary, as Figure 4B As shown, the first group of electrostatic protection sheets 440 of the physiological signal monitoring device 400 are arranged in a first area of ​​the outer surface of the strip 410, and the second group of electrostatic protection sheets 440 are arranged in a second area of ​​the outer surface of the strip 410, and cover multiple signal electrodes 420 in the thickness direction of the strip 410, so that the multiple signal electrodes 420 (for example, the first signal electrode 421, the second signal electrode 422) are located between the multiple electrostatic protection sheets 440 and the user's body.

[0141] The electrostatic protection sheet refers to a conductive sheet used to receive electrostatic charges on the outer surface of the physiological signal monitoring device (for example, electrostatic charges generated by friction between the human body and the clothes it wears). The material of the electrostatic protection sheet can be a conductive material with low hardness, such as conductive rubber, conductive silicone, etc.

[0142] In some embodiments, a plurality of electrostatic protection sheets are distributed side by side along the length direction of the tape strip.

[0143] In some embodiments, Figure 4BAs shown, multiple electrostatic protection sheets 440 are arranged in parallel along the length direction of the strip 410. Arranged in parallel means that the reference point of each electrostatic protection sheet in the multiple electrostatic protection sheets 440 is located on the same reference line, wherein the reference point of the electrostatic protection sheet can be preset (for example, preset as the geometric center point of the electrostatic protection sheet). The reference line refers to a straight line in the strip 410 that is parallel to the length direction of the strip 410 (for example, a center line in the strip 410 that is parallel to the length direction of the strip 410). The shape of each electrostatic protection sheet in the multiple electrostatic protection sheets 440 can be preselected (for example, as Figure 4B As shown, each electrostatic protection sheet is rectangular), the length of each electrostatic protection sheet in the length direction of the strip 410 in the multiple electrostatic protection sheets 440 can be the same or different, and the length of each electrostatic protection sheet in the width direction of the strip 410 in the multiple electrostatic protection sheets 440 can also be the same or different.

[0144] In some embodiments, Figure 4C As shown, multiple electrostatic protection sheets 440 are staggered along the length direction of the strip 410. Staggered distribution means that the reference points of at least some of the multiple electrostatic protection sheets 440 are not located on the same reference line. In some embodiments, multiple electrostatic protection sheets 440 can be arranged in parallel not only in the length direction, but also in the width direction, thereby forming a matrix distribution. Under this arrangement, it is equivalent to reducing the size of each electrostatic protection sheet in the length direction and / or width direction by increasing the number, thereby improving the softness or elasticity of the strip.

[0145] In some embodiments, the electrostatic protection sheets 440 at different positions may have the same size or distribution density. In some embodiments, the electrostatic protection sheets 440 at different positions may have different sizes or distribution densities. For example, the multiple electrostatic protection sheets at the outer surface facing the electrode 320 may have a larger size or be more densely distributed, thereby improving the electrostatic shielding effect of the electrostatic protection sheet on the electrode; the electrostatic protection sheets at other areas of the outer surface may have a smaller size or be more sparsely distributed, thereby ensuring that the strip 410 has better elasticity (especially in the buckle areas at both ends of the strip).

[0146] In some embodiments, at least some of the multiple electrostatic protection sheets are electrically connected through conductive wires.

[0147] For example, Figure 4B As shown, the electrostatic protection sheet 441 and the electrostatic protection sheet 442 in the plurality of electrostatic protection sheets 440 are connected to each other through a conductive wire 443 to achieve conduction between the electrostatic protection sheet 441 and the electrostatic protection sheet 442 .

[0148] In some embodiments of the present specification, at least some of the multiple electrostatic protection sheets are electrically connected by conductive wires, so that the multiple electrostatic protection sheets can form a large conductive area, which is beneficial to disperse the static electricity near the outer surface directly facing the signal electrode, thereby minimizing or eliminating the impact of the static electricity on the electrode.

[0149] In some embodiments, the distance between the connection points between two adjacent electrostatic protection sheets and the conductive line is smaller than the natural length of the conductive line.

[0150] For example, Figure 4B As shown, the distance between the connection points (connection point 443 - 1 and connection point 443 - 2 ) of the adjacent electrostatic protection sheets 441 and 442 and the conductive line 443 is smaller than the natural length of the conductive line 443 .

[0151] To achieve that the distance between the connection points of two adjacent electrostatic protection sheets and the conductive line is less than the natural length of the conductive line, the shape of the conductive line between two adjacent electrostatic protection sheets can be wavy, zigzag, etc., which is not limited here.

[0152] In some embodiments of the present specification, by setting the distance between the connection points of two adjacent electrostatic protection sheets and the conductive wire to be smaller than the natural length of the conductive wire, a length that can be reserved for stretching of the conductive wire can be reserved, thereby improving the stretchability of the conductive wire and further improving the stretchability of the physiological signal monitoring device.

[0153] In some embodiments, the conductive wire 443 is an elastic wire, and the conductive wire is arranged along the axial direction (with the conductive wire being Figure 4B The conductive wire 443 is elastically retractable (parallel to the length direction of the middle strip 410). For example, when the strip 410 is extended, the conductive wire 443 is also extended in the axial direction; for another example, when the strip 410 rebounds from the extended state, the conductive wire 443 is also shortened in the axial direction. The conductive wire 443 can be made of a mixed wire of a metal wire (for example, a silver wire) and an elastic wire (for example, a rubber wire).

[0154] In some embodiments of the present specification, the overall elasticity of the strip can be improved by setting the conductive wire as an elastic conductive wire.

[0155] In some embodiments, the multiple signal electrodes include a first signal electrode and a second signal electrode spaced apart along the length direction of the strip, and the multiple electrostatic protection sheets are electrically connected in sequence through conductive wires (so that the multiple electrostatic protection sheets are conductive), and the multiple electrostatic protection sheets form a conductive area, which covers the first signal electrode and the second signal electrode in the length direction of the strip.

[0156] For example, Figure 4A and Figure 4BAs shown, the plurality of signal electrodes 420 include a first signal electrode 421 and a second signal electrode 422 spaced apart and distributed along the length direction of the strip; Figure 4B As shown, at least some of the adjacent electrostatic protection sheets in the plurality of electrostatic protection sheets 440 are electrically connected by conductive wires (eg, conductive wires 443), and the plurality of electrostatic protection sheets 440 form an integral conductive region ( Figure 4B In order to make the multiple electrostatic protection sheets 440 form an integral conductive area, the first part (such as the multiple electrostatic protection sheets on the left) and the second part (such as the multiple electrostatic protection sheets on the right) of the multiple electrostatic protection sheets 440 are conductive, that is, the last electrostatic protection sheet 446 of the first part is conductive with the first electrostatic protection sheet 447 of the second part (not shown in the figure).

[0157] Figure 4D It is a front projection schematic diagram of another physiological signal monitoring device shown in some embodiments of this specification.

[0158] For example, Figure 4D As shown, the projected long side 421-1 of the first signal electrode 421 (the side of the projection area of ​​the first signal electrode 421 that is parallel to the length direction of the strip 410) and the projected long side 422-1 of the second signal electrode 422 (the side of the projection area of ​​the second signal electrode 422 that is parallel to the length direction of the strip 410) are both included in the projected long side 440-1 of the conductive area formed by the multiple electrostatic protection sheets 440 (the side of the projection area of ​​the conductive area formed by the multiple electrostatic protection sheets 440 that is parallel to the length direction of the strip 410), so that the conductive area formed by the multiple electrostatic protection sheets 440 covers the first signal electrode 421 and the second signal electrode 422 in the length direction of the strip 410.

[0159] In some embodiments of the present specification, since the static electricity that has the greatest impact on the signal electrode is the static electricity on the outer surface directly facing the signal electrode and its vicinity, by providing a conductive area to cover the two signal electrodes, the conductive area can disperse the static electricity near the outer surface directly facing the signal electrode, thereby minimizing or eliminating the impact of the static electricity on the signal electrode.

[0160] In some embodiments, the conductive region covers the first signal electrode and the second signal electrode in a width direction of the strip.

[0161] Figure 4E is a side projection schematic diagram of another physiological signal monitoring device according to some embodiments of this specification. Figure 4E The left and right figures in the figure are schematic side projection diagrams when observing from two opposite sides of the physiological signal monitoring device 400.

[0162] For example, Figure 4E As shown, the projected wide side 421-2 of the first signal electrode 421 (the side of the projection area of ​​the first signal electrode 421 that is parallel to the width direction of the strip 410) and the projected wide side 422-2 of the second signal electrode 422 (the side of the projection area of ​​the second signal electrode 422 that is parallel to the width direction of the strip 410) are both included in the projected wide side 440-2 of the conductive area formed by multiple electrostatic protection sheets 440 (the side of the projection area of ​​the conductive area formed by multiple electrostatic protection sheets 440 that is parallel to the width direction of the strip 410), so that the above-mentioned conductive area covers the first signal electrode 421 and the second signal electrode 422 in the width direction of the strip 410.

[0163] In some embodiments of the present specification, by providing a conductive region to cover two signal electrodes in the width direction, the conductive region can be able to absorb static electricity near the outer surfaces facing the two signal electrodes, thereby minimizing or eliminating the effect of the static electricity on the signal electrodes.

[0164] In some embodiments, the multiple signal electrodes include two first signal electrodes and a second signal electrode spaced apart along the length direction of the strip, a portion of the multiple electrostatic protection sheets are electrically connected by a conductive line to form a first conductive region, the first conductive region covers the outside of the first signal electrode, another portion of the multiple electrostatic protection sheets are electrically connected by a conductive line to form a second conductive region, the second conductive region covers the outside of the second signal electrode, and the first conductive region and the second conductive region are insulated from each other.

[0165] For example, Figure 4B As shown, at least some of the adjacent electrostatic protection sheets in the first part of the multiple electrostatic protection sheets 440 (such as the multiple electrostatic protection sheets on the left) are electrically connected in sequence through conductive wires (for example, conductive wires 443) to form a first conductive region 444, and the first conductive region 444 covers the outer side of the first signal electrode 421. At least some of the adjacent electrostatic protection sheets in the second part of the multiple electrostatic protection sheets 440 (such as the multiple electrostatic protection sheets on the right) are electrically connected in sequence through conductive wires to form a second conductive region 445, and the second conductive region 445 covers the outer side of the second signal electrode 422. The first conductive region 444 and the second conductive region 445 are insulated from each other, that is, there is no conduction between the last electrostatic protection sheet 446 of the first part and the first electrostatic protection sheet 447 of the second part.

[0166] In some embodiments of the present specification, by providing different conductive areas to cover corresponding electrodes, the different conductive areas can disperse static electricity near the outer surface facing the electrode, thereby minimizing or eliminating the effect of the static electricity on the electrode.

[0167] In some embodiments, the first conductive region covers the first signal electrode in the length direction of the strip, and the second conductive region covers the second signal electrode in the length direction of the strip.

[0168] Figure 4F 1 is another front view projection diagram of another physiological signal monitoring device shown in some embodiments of the present specification.

[0169] For example, Figure 4F As shown, the projected long side 421-1 of the first signal electrode 421 is contained within the projected long side 444-1 of the first conductive region 444 (the side of the projected region of the first conductive region 444 that is parallel to the length direction of the strip 410), and the projected long side 422-1 of the second signal electrode 422 is contained within the projected long side 445-1 of the second conductive region 445 (the side of the projected region of the second conductive region 445 that is parallel to the length direction of the strip 410), so that the first conductive region 444 covers the first signal electrode 421 in the length direction of the strip 310, and the second conductive region 445 covers the second electrode 422 in the length direction of the strip 310.

[0170] In some embodiments of the present specification, by setting different conductive areas to cover corresponding electrodes in the length direction of the strip, the different conductive areas can disperse static electricity near the outer surface facing the electrode, thereby minimizing or eliminating the effect of the static electricity on the electrode.

[0171] In some embodiments, the first conductive region covers the first signal electrode in the width direction of the strip, and the second conductive region covers the second signal electrode in the width direction of the strip.

[0172] Figure 4G is another side projection schematic diagram of another physiological signal monitoring device according to some embodiments of this specification. Figure 4G The left and right figures in the figure are schematic side projection diagrams when observing from two opposite sides of the physiological signal monitoring device 400.

[0173] For example, Figure 4GAs shown, the projected wide side 421-2 of the first signal electrode 421 is contained within the projected wide side 444-2 of the first conductive region 444 (the side of the projected region of the first conductive region 444 that is parallel to the width direction of the strip 410), and the projected wide side 422-2 of the second electrode 422 is contained within the projected wide side 445-2 of the second conductive region 445 (the side of the projected region of the second conductive region 445 that is parallel to the width direction of the strip 410), so that the first conductive region 444 covers the first signal electrode 421 in the width direction of the strip 410, and the second conductive region 445 covers the second signal electrode 422 in the width direction of the strip 410.

[0174] In some embodiments of the present specification, by setting different conductive areas to cover corresponding electrodes in the width direction of the strip, the different conductive areas can disperse static electricity near the outer surface facing the electrode, thereby minimizing or eliminating the effect of the static electricity on the electrode.

[0175] The ground electrode is located on the inner surface of the strip and is configured to connect the electrostatic protection sheet to the user's body to achieve electrostatic shielding for multiple signal electrodes. The material of the ground electrode can be a conductive material with low hardness, such as conductive rubber, conductive silicone, etc. For example, Figure 4A and Figure 4B As shown, the grounding electrode 450 of the physiological signal monitoring device 400 may include a grounding electrode 451 and a grounding electrode 452, and is arranged on the inner surface of the strip 410. When the user (for example, the monitored object 140) wears the physiological signal monitoring device 400, the grounding electrode 450 may fit the user's skin; the grounding electrode 450 may be respectively connected to multiple electrostatic protection sheets 440 (not shown in the figure) to receive the external surface electrostatic charges received by the multiple electrostatic protection sheets 440, and introduce them into the human body to achieve electrostatic shielding.

[0176] Different from Figure 4B In the embodiment shown in FIG. 1 , adjacent electrostatic protection sheets (eg, electrostatic protection sheet 441 and electrostatic protection sheet 442 ) are connected to each other via conductive lines. In other embodiments, adjacent electrostatic protection sheets may also be directly connected. Figure 4H 2 is an exemplary connection diagram of an electrostatic protection sheet according to some embodiments of this specification. Figure 4HAs shown, multiple electrostatic protection sheets are stacked in an end-to-end connection manner to form a bent structure, and adjacent electrostatic protection sheets are connected by ends, and the end connection positions are electrically conductive to achieve conduction between adjacent electrostatic protection sheets. In some embodiments, the bent structure formed by stacking multiple electrostatic protection sheets 440 can be elastically stretched along the length direction of the strip. Specifically, when an external force causes the strip 410 to be stretched along the length direction, the bending angle α of the bent structure becomes larger, and the size of the bent structure along the length direction of the strip 410 also increases accordingly (that is, the bending structure gradually changes from a bent shape to a straight shape); after the external force is removed, the bent structure also gradually returns to its original state, thereby achieving the bending structure being able to be elastically stretched along the length direction of the strip. The bending angle α refers to the angle formed when the ends of two adjacent electrostatic protection sheets are connected. In some embodiments, the multiple bending angles formed by multiple electrostatic protection sheets can be the same or different.

[0177] Figure 5A is a diagram showing verification results of a physiological signal monitoring device without antistatic design under high impedance state as shown in some embodiments of this specification; Figure 5B It is a verification result diagram of a physiological signal monitoring device with an anti-static design under a high impedance state as shown in some embodiments of this specification; Figure 5C is a diagram showing verification results of a physiological signal monitoring device without antistatic design under low resistance state as shown in some embodiments of this specification; Figure 5D This is a diagram showing the verification results of a physiological signal monitoring device with an anti-static design under low resistance conditions as shown in some embodiments of this specification.

[0178] It is known that the hygroscopicity and water storage capacity of the electrode (e.g., signal electrode) material of the physiological signal monitoring device itself will affect the antistatic effect. For example, compared with materials with weaker water absorption (e.g., polyester fiber), materials with stronger water absorption (e.g., cotton) have stronger antistatic effect. This is because the presence of water can provide a conductive path to help the flow of charge, thereby reducing static electricity accumulation.

[0179] It is precisely because the severity of static electricity is highly correlated with humidity, and a direct indicator of humidity is the different impedances from the electrode to the human body. Therefore, this specification verifies the anti-static effect of the physiological signal monitoring device in high-impedance state and low-impedance state. Among them, the high-impedance state means that when the physiological signal monitoring device is worn, the first electrode and the second electrode (for example, Figure 3A The impedance range between the first electrode 321 and the second electrode 322 is shown to be 1M ohm to 10M ohm. The low impedance state means that when the physiological signal monitoring device is worn, the impedance range between the first electrode and the second electrode is 100 ohm to 500K ohm.

[0180] The static electricity triggering method during verification is to use clothes blended from cotton and polyester fibers, and manually pull them along the width of the strip to create friction between the clothes and the strip, with the pulling amplitude and frequency remaining basically consistent.

[0181] The high resistance state and low resistance state can be achieved by applying water on the strip.

[0182] The resistance measurement method is as follows: the monitoring subject (eg, monitoring subject 140) wears the physiological signal monitoring device, and then measures the resistance between two connection ports (eg, Figure 3B The impedance on the connection port 323 and the connection port 324 shown (i.e., the impedance from the connection port to one electrode (extremely low impedance, within 10 ohms), the electrode to the human body, the inside of the human body (within 100 ohms), the human body to another electrode, and the other electrode to another connection port).

[0183] Figure 5A , Figure 5B , Figure 5C , Figure 5D In the figure, the ECG signal has almost no change, which is about 0.13mV. It should be noted that the ECG signal strengths in the above four figures seem to be different, but in fact they are basically the same, because the scales of the vertical axes of the figures are different.

[0184] Compared with the high impedance state Figure 5A and Figure 5B , Figure 5A The static electricity signal in the Figure 5A The signal-to-noise ratio is too small, and the excessive static signal affects the judgment of the ECG signal (such as Figure 5A As shown in the figure, the static signal almost drowns out the ECG signal. Figure 5B In the case of anti-static design, the static signal is significantly reduced, making Figure 5B The signal-to-noise ratio is improved, static electricity signals will not affect the judgment of ECG signals, and the anti-static effect is better.

[0185] Similarly, compared with the low resistance state Figure 5C and Figure 5D , compared with physiological signal monitoring devices without antistatic design Figure 5C , physiological signal monitoring device with anti-static design Figure 5D The signal-to-noise ratio is also improved.

[0186] It should be noted that, compared with the high-resistance state, the improvement of the signal-to-noise ratio in the low-resistance state is not very obvious. This is because the device itself has a stronger anti-static ability in the low-resistance state.

[0187] The basic concepts have been described above. Obviously, for those skilled in the art, the above detailed disclosure is only for example and does not constitute a limitation of this specification. Although not explicitly stated here, those skilled in the art may make various modifications, improvements and corrections to this specification. Such modifications, improvements and corrections are suggested in this specification, so such modifications, improvements and corrections still belong to the spirit and scope of the exemplary embodiments of this specification.
