TECHNICAL FIELD

[0001] The present application relates to the technical field of signal acquisition, in particular to a biological signal acquisition device. BACKGROUND

[0002] Obtaining electrophysiological signals is of great significance in current medical technology. The electrical activity of the heart (electrocardiogram, ECG), brain (electroencephalogram, EEG), nerves (electromyogram, EMG), or pregnant women (fetal electrocardiogram or fECG) or other electrical measurements (electrooculogram (EOG) for the eye, ERG EEG for intestinal activity, etc.) are usually recorded for monitoring purposes. Achieving correct measurement of electrophysiological signals requires precise positioning of the measurement electrodes. Correct placement of electrodes for stimulation or imaging is essential for accurate readings.

[0003] Currently, in the measurement of electroencephalogram, each electrode is connected to a detector by a copper wire, and the operator needs to manually fix each electrode, which is labor-intensive and inevitably risks electrode positioning errors due to human factors. In addition, in the traditional scheme, each electrode is connected to the device by an independent cable, which increases the risk of individual electrode falling off. SUMMARY

[0013] In some embodiments, the left middle temporal electrode and the left central electrode are on the same left first pre-made connector; or, the right middle temporal electrode and the right central electrode are on the same right first pre-made connector.

[0014] In some embodiments, the second pre-made connector on which the left frontal electrode and the right frontal electrode are located is longer than the second pre-made connector on which the middle frontal electrode is located, and the bending radius of the second pre-made connector on which the left frontal electrode and the right frontal electrode are located is smaller than the bending radius of the second pre-made connector on which the middle frontal electrode is located.

[0015] In some embodiments, further comprising an electrocardio electrode connected to the left first pre-made connector through a fourth pre-made connector.

[0016] In some embodiments, further comprising:

[0017] The left submandibular electrode and the right submandibular electrode are sequentially arranged along the left-right direction, and the left submandibular electrode and the right submandibular electrode are respectively connected to the concentrator through a fifth pre-made connector.

[0018] The left mastoid electrode and the right mastoid electrode are sequentially arranged along the left-right direction, and the left mastoid electrode and the right mastoid electrode are respectively connected to the concentrator through a sixth pre-made connector.

[0019] In the direction from front to back, the fifth pre-made connector, the sixth pre-made connector and the third pre-made connector are sequentially arranged side by side, and the length of the fifth pre-made connector is greater than the length of the sixth pre-made connector.

[0020] In some embodiments, further comprising a left eye electrode and a right eye electrode sequentially arranged in the front region along the left-right direction, the left eye electrode and the left frontal electrode are connected to the concentrator through a second pre-made connector; the right eye electrode and the right frontal electrode are connected to the concentrator through a second pre-made connector.

[0021] In some embodiments, the pre-made connector is a pre-made connecting sheet, and the width of the pre-made connecting sheet is 3-10mm.

[0022] In some embodiments, the pre-made connecting sheet comprises:

[0023] A PET substrate;

[0024] A silver paste channel printed on the surface of the PET substrate;

[0025] A polyethylene foam covering the surface of the silver paste channel.

[0026] Compared with the prior art, the present application has the following technical advantages:

[0027] (1) In the embodiment, the electrodes are positioned and arranged according to the brain parts required for collection, and each prefabricated connecting body is an elastic connecting body with a certain bending state and can be deformed appropriately. When in use, the quick connector of the concentrator is pre-inserted into the external detection device, and the concentrator is placed on the head with the central pole at the central part of the head; the left and right electrodes and the connecting bodies can be naturally overlapped on the parts required for detection and collection. Since the prefabricated connecting body has a deformable property, if the part overlapped by a certain electrode deviates from the target part, the operator can adjust the bending degree of the prefabricated connecting body where the electrode is located according to the deviation, so as to overlap the electrode on the required part. After the electrodes collect information and the information is concentrated on the concentrator, the quick connector can transmit the information to the detection device, the signal is uniformly transmitted with high efficiency, and it is also convenient for later maintenance.

[0028] (2) In the embodiment, different electrodes are connected to the concentrator through prefabricated connecting bodies, and the concentrator is placed in an accurate position, which can ensure that the positions of the electrodes will not deviate greatly, and the operator can further fine-tune to make each electrode accurately adhere to the required part. Therefore, the workload of the operator is greatly reduced; and since human intervention is relatively small, the accuracy of electrode positioning is greatly improved compared with the traditional way, and the detected data is more reliable; each electrode is connected to the concentrator through a prefabricated stable connecting body, and each electrode and the connecting body are closely related to form a whole and have a stable shape. After a single electrode is positioned and adhered, its position will be limited by the prefabricated connecting body, so it will not easily fall off.

[0029] (3) The present application realizes self-positioning of the electrodes, and allows ordinary users including those with general experience to use it due to little human intervention.

[0030] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the following preferred embodiments are described in detail below, and the accompanying drawings are described as follows. BRIEF DESCRIPTION OF DRAWINGS

[0043] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application.

Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0046] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0048] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0049] In routine monitoring, technicians or other qualified personnel are typically required to ensure the electrodes are correctly positioned on the body parts. This is because the nodes measuring the body's electrical activity need to be placed at specific points on the body to obtain the most accurate readings possible. Currently, in electrocardiogram (ECG) and electroencephalogram (EEG) measurements, each electrode is connected to the detector separately via a copper wire. This requires the operator to manually fix each electrode, which is labor-intensive and inherently carries the risk of electrode mispositioning due to human error. Furthermore, in traditional methods, each electrode uses an independent cable connected to the device, increasing the risk of individual electrodes becoming detached.

[0050] refer to Figures 1-2 This application provides a biosignal acquisition device, comprising:

[0051] A centralized sheet 10, a surface of the centralized sheet 10 is provided with a central pole point Cz, and the centralized sheet 10 is provided with a quick plug connector 11;

[0052] A left temporal middle electrode T3 and a left central electrode C3 are arranged in a direction gradually approaching the central pole point Cz and are connected to the centralized sheet 10 through a left prefabricated connecting body 110;

[0053] A right temporal middle electrode T4 and a right central electrode C4 are arranged in a direction gradually approaching the central pole point Cz and are connected to the centralized sheet 10 through a right prefabricated connecting body 120;

[0054] The area covered by the biological signal collector includes a front area and a rear area, with the left prefabricated connecting body 110 and the right prefabricated connecting body 120 as boundaries;

[0055] A left frontal electrode FP1, a frontal middle electrode Fz, and a right frontal electrode FP2 are sequentially arranged in the front area in a left-right direction, and the left frontal electrode FP1, the frontal middle electrode Fz, and the right frontal electrode FP2 are respectively connected to the centralized sheet 10 through a second prefabricated connecting body 200;

[0056] A left occipital electrode O1, a parietal electrode Pz, and a right occipital electrode O2 are sequentially arranged in the rear area in a left-right direction, and the left occipital electrode O1, the parietal electrode Pz, and the right occipital electrode O2 are respectively connected to the centralized sheet 10 through a third prefabricated connecting body 300;

[0057] The bending curvature of the left prefabricated connecting body 110 and the right prefabricated connecting body 120 is smaller than the bending curvature of the second prefabricated connecting body 200 and the third prefabricated connecting body 300.

[0058] Each electrode is arranged according to the required human brain collection site, and each prefabricated connecting body is a prefabricated elastic connecting body with a certain bending state and can be deformed appropriately. In use, the quick plug connector 11 of the centralized sheet 10 is pre-inserted into an external detection device, the centralized sheet 10 is placed on the top of the head, and the central pole point Cz is placed in the central part of the head; the left and right electrodes and the connecting bodies can be naturally lapped to the required detection and collection site. Due to the deformable property of the prefabricated connecting body, if the lapped site of a certain electrode deviates from the target site, the operator can adjust the bending degree of the prefabricated connecting body where the electrode is located according to the deviation, so as to lap the electrode to the required site. When the electrode is attached to the target site, the static friction force between the two makes the electrode stably attached to the target site. The information collected by each electrode is transmitted to the centralized sheet 10 through the corresponding prefabricated connecting body, and then transmitted to the detection device through the quick plug connector 11. The signal is transmitted uniformly, which is efficient and convenient for later maintenance.

[0059] The different electrodes are connected to the centralized sheet 10 through the prefabricated connectors in this embodiment. The centralized sheet 10 is placed in a position with high accuracy, so that the positions of the electrodes will not deviate greatly. The operator can then cooperate with fine adjustment to make each electrode accurately adhere to the required position. Therefore, the workload of the operator is greatly reduced. Since human intervention is relatively small, the accuracy of electrode positioning is greatly improved compared with the traditional method, and the detected data is more reliable. Each electrode is connected to the centralized sheet 10 through the prefabricated connector with a stable form. The electrodes and the connectors are closely related to each other to form a whole and have a stable form. After the positioning and adhesion of a single electrode, its position is limited by the prefabricated connector, so it will not easily fall off.

[0060] The present application realizes self-positioning of the electrodes. Since human factors interfere little, it allows people with general experience or other ordinary users to use it.

[0061] The temporal region is the position of the temple. For adults, the length from the left temporal middle to the right temporal middle does not change much, and a large adjustment amount is not needed. Therefore, the left first prefabricated connector 110 and the right first prefabricated connector 120 are designed to have a smaller bending radius.

[0062] However, the sizes of the forehead and the occipital region of different people differ greatly. Therefore, the bending radius of the second prefabricated connector 200 and the third prefabricated connector 300 is larger, which can provide a larger adjustment amount. When the distance between the forehead and the occipital region of the patient and the central pole Cz is large, the curved third prefabricated connector 300 can be pulled to a nearly straight state until it adheres to the required position.

[0063] Reference Figure 1 In some embodiments, the left temporal middle electrode T3 and the left central electrode C3 are on the same left first prefabricated connector 110, or the right temporal middle electrode T4 and the right central electrode C4 are on the same right first prefabricated connector 120. The distance between the positions where the left temporal middle electrode T3 and the left central electrode C3 adhere is relatively fixed. Therefore, the two electrodes are designed to be on the same connector, so that they do not need to be adjusted separately, saving workload and human intervention. The two electrodes are connected to the centralized sheet 10 through a prefabricated connector with a stable form. The two electrodes and the connector are closely related to each other and have a stable form. After the positioning and adhesion of a single electrode, its position is limited by the prefabricated connector, so it will not easily fall off, and it can also avoid easy sliding to cause errors in the detection data. Similarly, the right temporal middle electrode T4 and the right central electrode C4 are also designed in this way, which will not be described here.

[0064] Reference Figure 1In some embodiments, the second pre-prepared connecting body 200 where the left frontal electrode FP1 and the right frontal electrode FP2 are located is longer than the second pre-prepared connecting body 200 where the mid-frontal electrode Fz is located, and the curvature of the second pre-prepared connecting body 200 where the left frontal electrode FP1 and the right frontal electrode FP2 are located is smaller than the curvature of the second pre-prepared connecting body 200 where the mid-frontal electrode Fz is located. This design is because the part where the left frontal electrode FP1 and the right frontal electrode FP2 are attached is close to the eye socket, so the required second pre-prepared connecting body 200 is longer;

[0065] In addition, the area of the mid-frontal part is larger, and a larger adjustment is required to attach the mid-frontal electrode Fz to the required part, so the curvature of the second pre-prepared connecting body 200 where the mid-frontal electrode Fz is located is larger, which can provide a larger adjustment, and even the curved third pre-prepared connecting body 300 can be pulled to a nearly straight state until it is attached to the required part.

[0066] Reference Figure 1 In some embodiments, the electrocardio electrode ECG is further connected to the left pre-prepared connecting body 110 through a fourth pre-prepared connecting body 400. Specifically, the electrocardio electrode ECG enables the device to have electrocardio collection function. Generally, the heart is on the left side of the body, so the fourth pre-prepared connecting body 400 where the electrocardio electrode ECG is located is connected to the left pre-prepared connecting body 110; the left pre-prepared connecting body 110 is directly connected to the concentrator sheet 10, and the concentrator sheet 10 is accurately placed on the top of the head, which can ensure that the position of the electrocardio electrode ECG will not deviate greatly, and the operator can further adjust it to accurately attach the electrocardio electrode ECG near the heart. Therefore, the operator does not need to position the electrocardio electrode ECG separately, which greatly reduces the workload of the operator; and due to the reduction of human factors, the positioning accuracy of the electrocardio electrode ECG is greatly improved compared with the traditional way, and the detected data is more reliable; the electrocardio electrode ECG is connected to the concentrator sheet 10 through the pre-prepared connecting body with stable shape, and the connecting body connected to the electrocardio electrode ECG and other electrodes are closely related to each other to form a whole and have a stable shape. After the electrocardio electrode ECG is positioned and attached, its position is limited by the pre-prepared connecting body, so it will not easily fall off to cause detection failure.

[0067] The embodiment can simultaneously collect multiple physiological signals, avoid the time synchronization problem between different signals, and improve the accuracy of monitoring data of the same patient at the same time.

[0068] Reference Figure 1In some embodiments, a ground electrode GND and a reference electrode REF are also included, which are commonly connected to the central sheet 10 through a prefabricated connecting sheet. The ground electrode GND is used to ensure the safety of the detection process, and the reference electrode REF is used as a reference for comparison when measuring the potential of various electrodes. The two electrodes are commonly connected to the central sheet 10 through the same connecting body, and do not need to be adjusted separately, saving work and reducing human intervention; the two electrodes are connected to the central sheet 10 through a prefabricated connecting body with a stable shape. The mutual relationship between the two electrodes and the connecting body is close and the shape is stable. After the single electrode is positioned and attached, its position will be limited by the prefabricated connecting body, so it will not easily fall off and can also avoid easily sliding and affecting the detection data.

[0069] Reference Figure 1 In some embodiments, when the present application needs to detect more parts, such as for use in newborns, it also includes:

[0070] A left submental electrode S-L and a right submental electrode S-R are arranged in sequence along the left-right direction, and the left submental electrode S-L and the right submental electrode S-R are connected to the central sheet 10 through a fifth prefabricated connecting body 500, respectively;

[0071] A left mastoid electrode M1 and a right mastoid electrode M2 are arranged in sequence along the left-right direction, and the left mastoid electrode M1 and the right mastoid electrode M2 are connected to the central sheet 10 through a sixth prefabricated connecting body 600, respectively;

[0072] In the direction from front to back, the fifth prefabricated connecting body 500, the sixth prefabricated connecting body 600, and the third prefabricated connecting body 300 are arranged in sequence side by side, and the length of the fifth prefabricated connecting body 500 is greater than the length of the sixth prefabricated connecting body 600.

[0073] In this embodiment, the relative positions between the submental electrode, the mastoid electrode, the fifth prefabricated connecting body 500, and the sixth prefabricated connecting body 600 are designed according to the submental and mastoid parts to be collected, which can better match the human physiological structure. Each electrode is connected to the central sheet 10 through a corresponding prefabricated connecting body. The accurate placement of the central sheet 10 can ensure that the positions of the electrodes will not deviate greatly, and the operator can fine-tune to accurately attach each electrode to the desired part. Therefore, the workload of the operator is greatly reduced; and since human intervention is relatively less, the accuracy of electrode positioning is greatly improved compared to traditional methods, and the detected data is more reliable; each electrode is connected to the central sheet 10 through a prefabricated connecting body with a stable shape. The mutual relationship between the electrodes and the connecting body is close and the shape is stable. After the single electrode is positioned and attached, its position will be limited by the prefabricated connecting body, so it will not easily fall off.

[0074] Reference Figure 1In some embodiments, the application can further comprise a left eye electrode EOG1 and a right eye electrode EOG2, which are sequentially arranged in the front region along the left-right direction, and the left eye electrode EOG1 and the left frontal electrode FP1 are connected to the centralized sheet 10 through the second prefabricated connector 200; the right eye electrode EOG2 and the right frontal electrode FP2 are connected to the centralized sheet 10 through the second prefabricated connector 200.

[0075] Specifically, the left eye electrode EOG1 and the right eye electrode EOG2 enable the device to have an electrooculogram acquisition function. Since the areas collected by the left eye electrode EOG1 and the left frontal electrode FP1 are both near the left eye socket, and the areas collected by the right eye electrode EOG2 and the right frontal electrode FP2 are both near the right eye socket, the two electrodes on the same side with close distance and relatively fixed spacing are arranged on the second prefabricated connector 200, which does not need to be adjusted separately, saving work and reducing human intervention; each two electrodes are connected to the centralized sheet 10 through a prefabricated second prefabricated connector 200 with a stable shape, and the mutual association of the two electrodes and the second prefabricated connector 200 is close and stable in shape. After the single electrode is positioned and attached, its position will be limited by the prefabricated connector, so it will not easily fall off and can also avoid easily sliding to cause errors in detection data results. Similarly, the right temporal middle electrode T4 and the right central electrode C4 are also designed in this way, which will not be described here.

[0076] Reference Figure 1 In some embodiments, the prefabricated connector is a prefabricated connecting sheet. The prefabricated connecting sheet has a large contact area with the surface of the head and a large static friction force, which avoids detection errors caused by sliding during detection; and the sheet-shaped structure is not easy to twist or swing in a natural state, so the shape is relatively stable; when adjustment is needed, the operator can adjust the bending radius of the connecting sheet by applying a little force.

[0077] In some embodiments, as a preferred embodiment, the width of the prefabricated connecting sheet is 3-10 mm. When the width is less than 3 mm, the surface area is small, which may be easy to slide, and when the width is greater than 10 mm, the device as a whole is heavy, and the amount of material used is large, and the cost increases significantly.

[0078] In some embodiments, the prefabricated connecting sheet comprises:

[0079] a PET substrate;

[0080] a silver paste channel printed on the surface of the PET substrate;

[0081] a polyethylene foam covering the surface of the silver paste channel.

[0082] Specifically, the present application can adopt silver paste screen printing circuit process to print silver paste channels and electrode materials (Ag / AgCI) for electrical transmission on a PET substrate, and then cover the surface with a polyethylene foam insulation layer to ensure the excellent electrical conductivity and surface insulation performance of each channel, and only expose the electrode surface to the outside for attaching to the human body surface to collect signals. The prepared prefabricated connecting piece has certain morphological stability, and can be stretched to change its curvature under force, thereby facilitating adjustment to the surface of the required part; using flexible circuit printing technology, the weight of the sensor can be greatly reduced, making the device more portable.

[0083] At the same time, the surface of the prefabricated connecting piece in all areas that can contact the user's head is covered with a biocompatible, non-irritating, non-sensitizing, non-cytotoxic polyethylene protective foam, improving the comfort of the user and reducing the risk of skin allergy.

[0084] For the quick plug connector 11, PETG plastic can be used to reinforce the gold hand guide electrical structure part to ensure the structural strength; so that the product can be stably plugged into the adapter of the external detection device.

[0085] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.

[0086] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
