Description

A measuring electrode Technical Field

[0001] The present invention relates to the technical field of life signal detection, and in particular to a measuring electrode. Background Art

[0002] When performing physiological signal detection on animals, such as electrocardiogram (ECG) testing, the electrodes need to be in direct contact with the skin to collect physiological signals. Since animals have a lot of hair on their surfaces, ordinary electrodes cannot be directly attached to the skin. Generally, the animal's hair must be shaved before measurement can be performed, which is a cumbersome operation. Moreover, if the animal is awake, it may resist shaving, making shaving difficult. If the animal is being tested, shaving will affect the pet's appearance, which may also be a concern for the pet owner.

[0003] Therefore, there is an urgent need for an electrode that can measure animal physiological signals without shaving. Currently, two main methods are used for measurement. The first electrode structure includes a protrusion and conductive fibers on the protrusion. During measurement, the protrusion and the conductive fibers are used to contact the animal's skin to measure the ECG signal. The second electrode includes a pointed end. During measurement, the pointed end on the electrode is used to pierce the epidermis of the animal's skin to measure the ECG signal.

[0004] While all of the aforementioned solutions claim to be able to measure animal physiological signals without shaving, they overlook a key issue: when measuring animals, especially those that are awake, they will move. This can cause poor contact between the electrodes and the skin surface, or even detach from the skin, leading to poor or even lost physiological signals. Tightly attaching the electrodes to the animal to eliminate the effects of movement can cause significant discomfort and even puncture the skin. Technical issues

[0055] In existing technology, measuring electrodes employ either raised or puncture structures to contact the animal's skin. Both these structures are designed to penetrate the animal's hair to measure vital signs. However, the raised structures make point contact with the animal's skin, and animals are prone to shaking and other movements during measurement, which can cause the raised structures to intermittently separate from the animal's skin, affecting the electrode's continuous measurement and leading to inaccurate measurement data. Furthermore, the puncture structures, when inserted into the animal's tissue, can cause stinging and even harm.

[0056] The measuring electrode of the present application adopts a new electrical connection method, using a conductive liquid to achieve electrical connection between the electrode and the animal's body surface. The conductive liquid can pass through the hair on the animal's body surface, achieving a large-area electrical connection with the animal's body surface, improving the stability of the electrical connection. In addition, the electrical connection between the measuring electrode and the animal's body surface through the conductive liquid is similar to a flexible connection. The conductive liquid has a certain degree of deformability. When the animal shakes or moves, the conductive liquid can compensate for the gap between the animal's body surface and the measuring electrode, maintaining the stability and continuity of the electrical connection. In particular, when using a conductive liquid with a certain viscosity, the viscous conductive liquid can form a connection state that is not broken by drawing, and can further ensure that the measuring electrode is always electrically connected to the animal's body surface. Moreover, after the measurement is completed, it is only necessary to wipe off the conductive liquid on the animal's body surface, which will not cause damage to the animal's body surface and can avoid squeezing and puncturing the animal's body surface by the raised structure and the puncture structure. It should be noted that during use, the measuring electrode will be tied to the animal through an elastic bandage. When the animal moves or is active, the disconnection time and distance between the animal's body surface and the measuring electrode are relatively small. Therefore, within a smaller spatial range, the deformation of the conductive fluid is sufficient to maintain the electrical connection between the measuring electrode and the biological surface.

[0057] The measuring electrode of the present application mainly includes two parts: a liquid storage component and an electrical connection component. The liquid storage component has a liquid storage cavity that can store conductive liquid. The liquid storage cavity is an elastic cavity or a flexible cavity. By squeezing the liquid storage component, the conductive liquid in the liquid storage cavity can be squeezed out onto the skin of the animal. The electrical connection component is installed on the liquid storage component and is used to connect to an external device to transmit the measured signal to the measurement host. Among them, the measuring electrode can include multiple electrical connection methods, as follows:

[0058] The first method: the liquid storage component is an insulating structure, and the electrical connection component is electrically connected to the conductive liquid in the liquid storage chamber. During measurement, part of the conductive liquid in the liquid storage chamber is squeezed and discharged to the surface of the animal's body. The conductive liquid in the liquid storage chamber and the discharged conductive liquid are in a connected state. The electrical connection component is electrically connected to the skin of the biological body through the conductive liquid in the liquid storage chamber and the discharged conductive liquid in turn.

[0059] The second method involves a liquid storage component that is electrically conductive, and an electrical connection component that is electrically connected to the liquid storage component. During measurement, the liquid storage component contacts the surface of the biological body, and a portion of the conductive liquid in the liquid storage chamber is squeezed and discharged onto the animal's body surface. The electrical connection component is electrically connected to the biological skin through the liquid storage component. The electrical connection component can also be electrically connected to the biological skin through the liquid storage component and the discharged conductive liquid in sequence. Furthermore, the electrical connection component can also be electrically connected to the biological skin through the conductive liquid in the liquid storage chamber and the discharged conductive liquid in sequence. In other words, in this solution, three conductive paths are formed between the electrical connection component and the biological skin. Even if the liquid storage component is temporarily separated from the biological skin, the electrical connection component can still achieve electrical connection to the biological skin through two of its paths through the conductive liquid.

[0060] The present invention will be further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions, and for those skilled in the art, it is not necessary to describe these related operations in detail. They will fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0061] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0062] Component numbers used herein, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0063] In one embodiment, a measuring electrode is provided. This measuring electrode is primarily used to measure vital signs on the surface of an animal. The measuring electrode can be connected to a wearable device, such as an elastic bandage, which can be used to bind or wear the measuring electrode to the animal. Of course, this measuring electrode can also be used to measure other living organisms, such as collecting signals from the human head.

[0064] In this embodiment, the measuring electrodes use a conductive liquid as a conductive medium to achieve electrical connection with the skin of the animal. When the animal moves during measurement and the measuring electrodes are temporarily separated from the skin, the conductive liquid maintains electrical connection, ensuring stable and accurate measurement. In particular, using a conductive liquid with a certain viscosity provides a better and more stable electrical connection.

[0065] Referring to Figures 1-6 , in this embodiment, the measuring electrode primarily comprises a liquid storage component 1 and an electrical connection component 2. Liquid storage component 1 comprises a liquid storage chamber 11 for storing a conductive liquid 3. Liquid storage component 1 may be a flat, sac-like structure and have a contact surface 12 for contacting a biological surface. Contact surface 12 may be flat. Contact surface 12 has a drainage channel 13 communicating with liquid storage chamber 11. Drainage channel 13 may be in the form of a hole, an opening, or a linear slit. Liquid storage chamber 11 communicates with the outside world through drainage channel 13.

[0066] The liquid storage component 1 has a deformable structure, making the liquid storage cavity 11 an elastic cavity. The liquid storage component 1 is used to discharge the conductive liquid 3 in the liquid storage cavity 11 from the drainage channel 13 through deformation. The discharged conductive liquid 3 contacts the biological surface 4. The conductive liquid 3 can pass through the hair 41 on the biological surface 4 and contact the skin of the biological surface 4; at the same time, there is also conductive liquid 3 in the drainage channel 13, so that the discharged conductive liquid 3 can be connected to the conductive liquid 3 in the liquid storage cavity 11 to maintain electrical connection.

[0067] The deformable structure of the liquid storage component 1 can be a flexible structure. For example, the deformable structure of the liquid storage component 1 is made of elastic material such as rubber or silicone. When the measuring electrode is worn on the biological surface 4, the restraining force will squeeze the deformable structure of the liquid storage component 1 and squeeze out the conductive liquid 3.

[0068] The entire liquid storage component 1 can be a deformable structure, that is, the entire liquid storage component 1 is made of an elastic material structure such as rubber or silicone, which can not only form an elastic liquid storage cavity 11, but also form a deformable contact surface 12, so that when the contact surface 12 is placed on the biological surface 4, it can be appropriately deformed according to the shape of the biological surface 4, which can increase the fit between the contact surface 12 and the biological surface 4 and reduce the gap between the biological surface 4 and the contact surface 12 (the two are separated by hair 41), so that less conductive liquid 3 can fill the gap, which is beneficial to improving the stability of the electrical connection.

[0069] In other embodiments, the liquid storage component 1 can also be set to a partially deformable structure, for example, the contact surface 12 of the liquid storage component 1 and the part close to the contact surface 12 are flexible structures, which can also achieve the deformation of the liquid storage cavity 11 and the deformation fitting of the contact surface 12.

[0070] Referring to FIG. 7 , in other embodiments, the liquid storage component 1 may also be configured as another deformable structure, that is, the deformable structure may be a non-flexible structure that can be expanded and folded along the opening direction of the liquid discharge channel 13. Alternatively, the deformable structure of the liquid storage component 1 may be a non-flexible structure that can be expanded and folded in a direction perpendicular or substantially perpendicular to the contact surface 12. That is, the liquid storage component 1 may have a wavy, corrugated sidewall perpendicular to the contact surface 12. When the liquid storage component 1 is squeezed in a direction perpendicular or substantially perpendicular to the contact surface 12, the wavy sidewall will expand and contract, thereby similarly discharging the conductive liquid 3 from the liquid storage chamber 11.

[0071] In this embodiment, the electrical connection component 2 is connected to the liquid storage component 1, and the electrical connection component 2 is arranged at one end of the liquid storage component 1 away from the contact surface 12. The electrical connection component 2 has a first part and a second part. The first part of the electrical connection component 2 is used to electrically connect to the conductive liquid 3 in the liquid storage chamber 11, and the second part of the electrical connection component 2 is used to electrically connect to the measuring host 8. The electrical connection component 2 serves as a component connected to the outside and transmits the collected signal to the measuring host 8. Part or all of the first part of the electrical connection component 2 extends into the liquid storage chamber 11, or part or all of the first part encloses the wall of the liquid storage chamber 11. The first part of the electrical connection component 2 is used to electrically connect to the conductive liquid 3 in the liquid storage chamber 11, so that the electrical connection component 2 can be electrically connected to the biological surface 4 through the conductive liquid 3 in the liquid storage chamber 11 and the discharged conductive liquid 3 in sequence. The first portion of the electrical connection component 2 can partially or completely extend into the interior of the liquid storage chamber 11, so that the first portion of the electrical connection component 2 is electrically connected to the conductive liquid 3 in the liquid storage chamber 11; or, the first portion of the electrical connection component 2 can partially or completely be the cavity wall enclosing the liquid storage chamber 11, which can also enable the first portion of the electrical connection component 2 to be electrically connected to the conductive liquid 3 in the liquid storage chamber 11.

[0072] The electrical connection component 2 can be connected to an elastic bandage 5, which can be used to bind the measuring electrode to the body. The elastic bandage 5 compresses and deforms the liquid storage component 1 during binding, discharging the conductive liquid 3 within the liquid storage chamber 11. The discharged conductive liquid 3 can then pass through the hair 41 and electrically connect to the body surface 4. The electrical connection component 2 can be provided with a connection portion for connecting to the elastic bandage 5, such as a connecting ring.

[0073] The electrical connection component 2 may include a base 21 and an electrical connection terminal 22. The base 21 is connected to the liquid storage component 1, and the electrical connection terminal 22 is connected to the side of the base 21 facing away from the liquid storage component 1. The base 21 may be a plate-like structure. The liquid storage component 1 may have a mounting opening 14 at its upper end. The base 21 is mounted in the mounting opening 14, and the edge of the base 21 is sealed to the mounting opening 14, so that the base 21 and the liquid storage component 1 enclose a liquid storage cavity 11. The side of the base 21 facing the liquid storage cavity 11 is a conductive surface 23, which forms the cavity wall of the liquid storage cavity 11. The conductive surface 23 of the base 21 (i.e., the side of the base 21 facing away from the electrical connection terminal 22) constitutes the first portion of the electrical connection component 2. The end of the electrical connection terminal 22 facing away from the base 21 is used for electrical connection to the measurement host 8, and the end of the electrical connection terminal 22 facing away from the base 21 constitutes the second portion of the electrical connection component 2.

[0074] Contact surface 12 may be a circular surface with a diameter ranging from 30 to 40 mm, for example, 35 mm. Conductive surface 23 may be a circular surface with a diameter ranging from 10 to 40 mm, for example, 20 mm. In other embodiments, contact surface 12 and conductive surface 23 may also have other shapes, such as square or oval.

[0075] In this embodiment, the axial thickness range of the liquid storage component 1 (the height in the vertical direction) is 3-6 mm. For example, the thickness of the liquid storage component 1 is 4 mm. The thickness of the liquid storage component 1 is relatively small, and the height of the liquid storage cavity 11 is also small. Therefore, during the measurement process, the conductive surface 23 can always be connected to the conductive liquid 3 in the liquid storage cavity 11, ensuring the stability of the electrical connection.

[0076] In the use state (when the liquid storage component 1 is deformed), the straight-line distance between the conductive surface 23 and the contact surface 12 is L1; in the natural state (when the liquid storage component 1 is not deformed), the straight-line distance between the conductive surface 23 and the contact surface 12 is L2, and L1<L2; in the use state, the conductive surface 23 achieves electrical conduction with the biological surface 4 through the conductive liquid 3 in the liquid storage cavity 11.

[0077] The base 21 may be a circular plate structure, and the liquid storage component 1 may be a circular bowl-shaped structure. The base 21 and the liquid storage component 1 are connected to form a circular flat structure.

[0078] The base 21 and the electrical connection terminals 22 are both conductive structures, such as being made of a conductive metal. The base 21 and the electrical connection terminals 22 can be an integrated structure, or they can be secured together by threading, welding, or snapping. The electrical connection terminals 22, the base 21, the conductive liquid 3 in the liquid storage chamber 11, the conductive liquid 3 in the liquid discharge channel 13, the discharged conductive liquid 3, and the biological surface 4 are sequentially connected in series to form an electrical connection.

[0079] In other embodiments, the electrical connection component 2 may also include a substrate 21 and an electrical connection wire. The electrical connection wire may be used instead of the electrical connection terminal 22 to achieve electrical connection between the electrical connection component 2 and the measurement host 8 .

[0080] In this embodiment, the sidewall of the mounting opening 14 of the liquid storage component 1 may be provided with a slot 141, and the edge of the base 21 is connected to the slot 141 to form a sealed connection. The liquid storage component 1 may be made of a material such as rubber or silicone, so that the slot 141 of the mounting opening 14 has a certain degree of elasticity. The thickness of the base 21 may be slightly greater than the width of the slot 141, and the slot 141 elastically deforms to wrap around the edge of the base 21 to form a sealed connection.

[0081] In other embodiments, the edge of the base 21 may also be sealed and connected to the mounting opening 14 by bonding or other means, thereby achieving a sealed connection between the base 21 and the liquid storage component 1 and enclosing the liquid storage cavity 11 .

[0082] In this embodiment, the base 21 may be provided with a liquid adding hole 211, which is in communication with the liquid storage chamber 11 and is used to add the conductive liquid 3 into the liquid storage chamber 11. A sealing member 212 is also provided on the liquid adding hole 211. The sealing member 212 may be a plug structure having a certain degree of elasticity and is detachably connected to the liquid adding hole 211.

[0083] Please refer to Figure 4. When the conductive liquid 3 needs to be added, the blocking piece 212 is pulled out, and the conductive liquid container 7 is plugged into the liquid adding hole 211. The conductive liquid container 7 can inject the conductive liquid 3 into the liquid storage chamber 11 through the liquid adding hole 211. When the conductive liquid 3 is added, the blocking piece 212 is blocked in the liquid adding hole 211 to achieve sealing of the liquid adding hole 211, thereby preventing the conductive liquid in the liquid storage chamber 11 from overflowing and volatilizing.

[0084] The blocking member 212 can be connected to the base 21 or the liquid storage component 1 through a flexible connector 213. The blocking member 212 can move through the flexible connector 213 to close and open the liquid filling hole 211. The connector 213 connects the blocking member 212 to the base 21 or the liquid storage component 1, which can prevent the blocking member 212 from being lost. For example, the blocking member 212, the connector 213 and the liquid storage component 1 are an integrated structure, and the three are integrally formed. The connector 213 is parallel to the base 21. The connector 213 can also act as a force arm to press the blocking member 212 into the liquid filling hole 211 to improve the sealing performance of the blocking member 212. The connector 213 can also be a connecting wire that ties the blocking member 212 to the base 21 or the liquid storage component 1, which can also prevent the blocking member 212 from being lost.

[0085] In other embodiments, the liquid-adding hole 211 may also be provided on the sidewall of the liquid-storage component 1, or the area of ​​the base 21 parallel to the contact surface 12 may be approximately half of that in this embodiment, with the remaining half of the base 21 area being extended and closed by the liquid-storage component 1. In other words, the liquid-storage component 1 may have a flat surface on the side facing away from the contact surface 12, and the liquid-adding hole 211 may be provided on this surface. The liquid-adding hole 211 provided on the liquid-storage component 1 may also be connected to the liquid storage chamber 11 to facilitate the addition of the conductive liquid 3.

[0086] In this embodiment, the sidewall of the mounting opening 14 is further provided with a first limiting portion 142, and the base 21 is provided with a second limiting portion 214. The first limiting portion 142 and the second limiting portion 214 are connected to limit the rotational freedom of the base 21 relative to the mounting opening 14, that is, to limit the rotational freedom of the electrical connection component 2 relative to the liquid storage component 1, thereby improving the structural connection stability between the electrical connection component 2 and the liquid storage component 1 and ensuring the stability of the electrical connection. The first limiting portion 142 also serves to circumferentially locate the circumferential position of the liquid filling hole 211, so that after the base 21 is installed in the mounting opening 14, the liquid filling hole 211 can be axially aligned with the sealing member 212.

[0087] The first limiting portion 142 may be a protruding structure extending radially along the mounting opening 14 . Correspondingly, the second limiting portion 214 may be a radial limiting groove on the edge of the base 21 . The protruding structure is engaged in the limiting groove to limit the rotational freedom of the base 21 .

[0088] In other embodiments, the first limiting portion 142 may also be a limiting groove, and the second limiting portion 214 may be a protruding structure, which can also achieve circumferential rotation limiting and circumferential position positioning of the base 21 relative to the mounting opening 14 .

[0089] Please refer to Figure 5, which shows the measuring electrode in state 1. This state, which accounts for the majority of the measurement process, allows the electrical connection component 2 to form a stable electrical connection with the biological surface 4. The measuring electrode can be secured to the biological surface 4, which has hair 41, via an elastic bandage 5. The contact surface 12 of the measuring electrode is in contact with the biological surface 4, restrained by the elastic bandage 5. At this point, the liquid reservoir 1 is squeezed and deformed, forcing the conductive liquid 3 within the reservoir 1 out of the liquid reservoir cavity 11 and into the space between the contact surface 12 and the biological surface 4.

[0090] Please refer to Figure 6, which shows the second wearing state of the measuring electrode. The second wearing state of the measuring electrode is that the animal moves during the measurement process, resulting in a certain gap between the contact surface 12 and the biological surface 4. The discharged conductive liquid 3 can fill and compensate for the gap between the contact surface 12 and the biological surface 4, so that the electrical connection component 2 can maintain a stable electrical connection with the biological surface 4.

[0091] In the measuring electrode of this embodiment, the electrical connection component 2 contacts the biological surface 4 through the liquid storage component 1, and the liquid storage component 1 can store a conductive liquid 3. The liquid storage component 1 also has a contact surface 12 that contacts the biological surface 4, and the contact surface 12 has a liquid discharge channel 13. The liquid storage component 1 has a deformable structure, and the liquid storage component 1 can discharge the conductive liquid 3 by deformation. The conductive liquid 3 can be connected between the biological surface 4 and the contact surface 12, so that during the measurement process, the conductive liquid 3 in the liquid storage chamber 11 can be electrically connected to the biological surface 4 through the discharged conductive liquid 3; and the electrical connection component 2 has a first portion that is electrically connected to the conductive liquid 3 in the liquid storage chamber 11, so that During the measurement process, the electrical connection component 2 can form an electrical connection with the biological surface 4 through the conductive liquid 3 in the liquid storage chamber 11 and the discharged conductive liquid 3; the conductive liquid 3 can pass through the hair on the biological surface 4 and electrically connect with the skin of the biological surface 4, and can form a stable electrical connection. Even if the biological body moves during the measurement process, the conductive liquid 3 forms a flexible electrical connection with a certain deformation ability and can achieve large-area contact with the biological surface 4, which can ensure that the electrical connection component always maintains electrical connection with the skin of the biological surface 4; and the conductive liquid 3 is used to achieve electrical connection, and the conductive liquid 3 can be wiped off after the measurement is completed, which will not cause discomfort to the biological body.

[0092] In this embodiment, the measuring electrode is shipped without conductive liquid 3 in the liquid storage chamber 11. Before use, conductive liquid 3 is added to the liquid storage chamber 11 through the liquid filling port 211. This allows for extended storage of the conductive liquid 3 in the liquid storage chamber 11, enabling repeated use of the measuring electrode. It should be noted that due to the tension of the conductive liquid 3, especially when it has a certain viscosity, even after some of the conductive liquid 3 is consumed, the conductive liquid 3 can still be electrically connected to the conductive liquid 3 in the liquid storage chamber 11 through the sidewalls.

[0093] In other embodiments, the liquid storage chamber 11 of the measuring electrode may contain conductive liquid 3 when it leaves the factory. When a certain amount of conductive liquid 3 in the liquid storage chamber 11 is consumed, the conductive liquid 3 can be added to the liquid storage chamber 11 through the liquid filling hole 211.

[0094] In this embodiment, the liquid storage component 1 can be a conductive structure, the liquid storage component 1 can be a conductive structure as a whole, or the outer surface of the liquid storage component 1 can be provided with a conductive layer. In addition to achieving electrical connection with the biological surface 4 through the conductive liquid 3 in the liquid storage chamber 11, the electrical connection component 2 can also achieve electrical connection with the biological surface 4 through the liquid storage component 1. The conductive setting of the liquid storage component 1 allows the electrical connection component 2 to have more paths for electrical connection with the biological surface 4, which can improve the stability of the electrical connection between the electrical connection component 2 and the biological surface 4. Among them, the electrical connection between the electrical connection component 2 and the biological surface 4 through the liquid storage component 1 can include two electrical connection paths: a first path, in which the electrical connection component 2, the liquid storage component 1 and the biological surface 4 are electrically connected in sequence; a second path, in which the electrical connection component 2, the liquid storage component 1, the discharged conductive liquid 3 and the biological surface 4 are electrically connected in sequence.

[0095] In other embodiments, the liquid storage component 1 may also be an insulating structure, and the electrical connection component 2 may be electrically connected to the biological surface 4 through the conductive liquid 3 in the liquid storage cavity 11 and the discharged conductive liquid 3.

[0096] In one embodiment, the contact surface 12 of the liquid storage component 1 can be provided with multiple drainage channels 13. The multiple drainage channels 13 can be distributed along a circular array or a rectangular array. The multiple drainage channels 13 can be arranged on a single circular trajectory or on multiple concentric circular trajectories. Referring to Figures 8a-8d, the multiple drainage channels 13 are distributed on a single circular trajectory, and the circular trajectory on which the multiple drainage channels 13 are located is concentric with the circular contact surface 12.

[0097] The drainage channel 13 can be a drainage hole, a drainage slit, or other structure. Referring to Figure 8a, the drainage channel 13 is a drainage hole with a sufficiently small diameter to prevent the conductive liquid 3 from flowing out when not squeezed (when the liquid storage component 1 is undeformed). When not squeezed (when the liquid storage component 1 is deformed), the drainage hole slightly opens to discharge the conductive liquid 3. Referring to Figures 8b-8d, the drainage channel 13 can be a drainage slit structure with a straight, cross, or Y-shaped interface. When not squeezed (when the liquid storage component 1 is undeformed), the drainage slit is closed; when not squeezed (when the liquid storage component 1 is deformed), the drainage slit opens to discharge the conductive liquid 3. The drainage slit also prevents the conductive liquid 3 from flowing out when not squeezed (when the liquid storage component 1 is undeformed).

[0098] Referring to Figure 9 , in one embodiment, the contact surface 12 of the liquid storage component 1 is provided with a raised structure 121. Multiple raised structures 121 may be provided on the contact surface 12, and the drainage channel 13 may be provided on the raised structure 121. The raised structure 121 allows the drainage channel 13 to more easily penetrate animal hair, allowing the conductive liquid 3 to be discharged directly onto the skin of the biological surface 4. The provision of the raised structure 121 also causes the liquid storage component 1 to deform when worn, facilitating the discharge of the conductive liquid 3.

[0099] The raised structure 121 may be a semicircular structure or other arc-shaped structure. The smooth end of the raised structure 121 will not sting the animal.

[0100] The raised structure 121 is formed by the raised contact surface 12 , that is, the raised structure 121 forms the inner wall of the liquid storage cavity 11 , so that the liquid storage cavity 11 can be deformed after the raised structure 121 contacts and squeezes the biological surface 4 , which is more conducive to discharging the conductive liquid 3 .

[0101] In one embodiment, a buffer support 15 is provided in the liquid storage cavity 11 of the liquid storage component 1. The buffer support 15 can provide a certain supporting force to the liquid storage cavity 11 so as to control the deformation of the liquid storage cavity 11 during wearing, that is, to control the discharge amount of the conductive liquid 3.

[0102] The buffer support 15 may include an elastic structure, which can provide elastic support force to the liquid storage chamber 11, so that the liquid storage chamber 11 can slow down the deformation speed of the liquid storage chamber 11 during wearing, and can slow down the discharge speed and discharge amount of the conductive liquid 3. The elastic structure has a better buffering effect.

[0103] The buffer support 15 is arranged on the cavity wall of the liquid storage cavity 11 close to the contact surface 12. The buffer support 15 is closer to the contact surface 12, so that when the liquid storage component 1 is squeezed toward the contact surface 12, the buffer support 15 can provide more stable support.

[0104] Referring to Figures 10a-10d, the buffer support member 15 may be a sponge, a spring, a columnar structure, or a conical structure. The buffer support member 15 is arranged perpendicular to the contact surface 12, enabling the sponge, spring, columnar structure, or conical structure to provide support to the liquid storage chamber 11 along the buffer support member 15. The sponge may be a single-piece structure or a multi-piece structure arranged at intervals. The spring, columnar structure, or conical structure may include multiple structures arranged at intervals. The spring, columnar structure, or conical structure may be evenly distributed in a circular or rectangular array, providing a more stable and uniform support force, allowing the multiple drainage channels 13 to discharge the conductive liquid 3 uniformly.

[0105] In one embodiment, the measuring electrode can be a split structure, which is assembled before use. The assembled measuring electrode can also measure the signal of the biological body. The split structure of the measuring electrode is convenient for storage and transportation of the measuring electrode.

[0106] Referring to Figures 10-14, the measuring electrode includes a liquid storage component 1, an electrical connection component 2, and a sealing member 6. Liquid storage component 1 has a liquid storage chamber 11 for storing a conductive liquid 3. Liquid storage component 1 can be a flat, sac-like structure with a contact surface 12 for contacting a biological surface. Contact surface 12 can be a flat surface. Contact surface 12 has a drainage channel 13 communicating with liquid storage chamber 11. Drainage channel 13 can have a hole-like, orifice-like, or linear slit-like structure. Liquid storage chamber 11 communicates with the outside world through drainage channel 13.

[0107] The liquid storage component 1 has a deformable structure, making the liquid storage cavity 11 an elastic cavity. The liquid storage component 1 is used to discharge the conductive liquid 3 in the liquid storage cavity 11 from the drainage channel 13 through deformation. The discharged conductive liquid 3 contacts the biological surface 4. The conductive liquid 3 can pass through the hair 41 on the biological surface 4 and contact the skin of the biological surface 4; at the same time, there is also conductive liquid 3 in the drainage channel 13, so that the discharged conductive liquid 3 can be connected with the conductive liquid 3 in the liquid storage cavity 11, that is, maintain electrical connection.

[0108] The deformable structure of the liquid storage component 1 can be a flexible structure. For example, the deformable structure of the liquid storage component 1 is made of elastic material such as rubber or silicone. When the measuring electrode is worn on the biological surface 4, the restraining force will squeeze the deformable structure of the liquid storage component 1 and squeeze out the conductive liquid 3.

[0109] The entire liquid storage component 1 can be a deformable structure, that is, the entire liquid storage component 1 is made of an elastic material structure such as rubber or silicone, which can not only form an elastic liquid storage cavity 11, but also form a deformable contact surface 12, so that when the contact surface 12 is placed on the biological surface 4, it can be appropriately deformed according to the shape of the biological surface 4, which can increase the fit between the contact surface 12 and the biological surface 4 and reduce the gap between the biological surface 4 and the contact surface 12 (the two are separated by hair 41), so that less conductive liquid 3 can fill the gap, which is beneficial to improving the stability of the electrical connection.

[0110] In other embodiments, the liquid storage component 1 can also be set to a partially deformable structure, for example, the contact surface 12 of the liquid storage component 1 and the part close to the contact surface 12 are flexible structures, which can also achieve the deformation of the liquid storage cavity 11 and the deformation fitting of the contact surface 12.

[0111] In other embodiments, the liquid storage component 1 can also be set as other deformable structures. For example, the deformable structure of the liquid storage component 1 is a non-flexible structure that can be stretched and folded in a direction perpendicular or approximately perpendicular to the contact surface 12, that is, the liquid storage component 1 has a wavy side wall perpendicular to the contact surface 12. When the liquid storage component 1 is squeezed in a direction perpendicular or approximately perpendicular to the contact surface 12, the wavy side wall will stretch and contract, and can also discharge the conductive liquid 3 in the liquid storage chamber 11.

[0112] In this embodiment, the liquid storage component 1 further includes a mounting surface 16 that is spaced apart from the contact surface 12 and can be parallel to the contact surface 12. A connecting channel 161 is provided on the mounting surface 16. The connecting channel 161 communicates with the liquid storage chamber 11. The connecting channel 161 can be a connecting hole, a connecting port, or other connecting structure. The aperture or diameter of the connecting channel 161 can be larger than that of the liquid discharge channel 13. The larger aperture or diameter of the connecting channel 161 facilitates electrical connection with the electrical connection component 2.

[0113] The liquid storage component 1 may include a liquid storage cup 1a, an upper cover 1b, and a lower cover 1c. The upper end of the liquid storage cup 1a has an opening, the lower end of the liquid storage cup 1a serves as a contact surface 12, and the lower end of the liquid storage cup 1a has a drainage channel 13. The upper cover 1b is secured to the upper end of the liquid storage cup 1a by bonding, welding, or other means, sealing the upper opening of the liquid storage cup 1a. The upper surface of the upper cover 1b serves as a mounting surface 16, and the upper cover 1b has a connecting channel 161. The lower cover 1c is removably secured to the bottom surface (contact surface 12) of the liquid storage cup 1a. The lower cover 1c may be made of adhesive release paper or other film. The area of ​​the lower cover 1c can be larger than the bottom surface of the liquid storage cup 1a, or the area of ​​the bottom surface of the liquid storage cup 1a is larger than the area of ​​the drainage channel 13 within the bottom surface of the liquid storage cup 1a, so that the lower cover 1c can completely seal all drainage channels 13. The lower cover 1c may be provided with an easy-tear structure radially protruding from the liquid storage cup 1a, so as to facilitate tearing off the lower cover 1c during use.

[0114] The upper cover 1b may also be provided with an easy-tear structure, which protrudes radially from the electrical connection component 2, so that after the electrical connection component 2 is installed on the upper cover 1b, the electrical connection component 2 can be separated from the upper cover 1b through the easy-tear structure. After separation, the conductive liquid 3 can be added for reuse.

[0115] In other embodiments, the drainage channel 13 is configured as a smaller aperture, or the drainage channel 13 is in a closed state, and the lower cover 1c may not be provided, and the conductive liquid 3 in the liquid storage chamber 11 will not automatically flow out.

[0116] In other embodiments, the liquid storage cup 1a and the upper cover 1b may be an integrated structure.

[0117] In this embodiment, the seal 6 is removably mounted on the mounting surface 16 of the liquid storage component 1, covering the connecting channel 161. In other words, the seal 6 is mounted on the upper surface of the upper cover 1b. The seal 6 and the liquid storage component 1 form a single structure, allowing the liquid storage component 1 to be stored and transported separately.

[0118] The seal 6 can be a release paper or other film structure, and the mounting surface 16 can be provided as an adhesive surface, and the seal 6 is fixed to the mounting surface 16 by the adhesive property of the mounting surface 16. After the seal 6 on the mounting surface 16 is removed, the adhesive mounting surface 16 can be bonded and fixed to the electrical connection component 2.

[0119] During use, the seal 6 on the mounting surface 16 is removed, and the electrical connection component 2 is connected to the mounting surface 16 of the liquid storage component 1. The electrical connection component 2 has a first portion and a second portion. The first portion of the electrical connection component 2 is used to electrically connect to the conductive liquid 3 in the liquid storage chamber 11 through the connection channel 161, and the second portion of the electrical connection component 2 is used to electrically connect to the measurement host 8. The electrical connection component 2, as a component connected to the outside, transmits the collected signals to the measurement host 8. The first portion of the electrical connection component 2 is used to electrically connect to the conductive liquid 3 in the liquid storage chamber 11, allowing the electrical connection component 2 to electrically connect to the biological surface 4 through the conductive liquid 3 in the liquid storage chamber 11 and the discharged conductive liquid 3. The first portion of the electrical connection component 2 can partially or completely extend into the interior of the liquid storage chamber 11, thereby electrically connecting the first portion of the electrical connection component 2 to the conductive liquid 3 in the liquid storage chamber 11; alternatively, the first portion of the electrical connection component 2 can partially or completely form the wall surrounding the liquid storage chamber 11, thereby also electrically connecting the first portion of the connection component 2 to the conductive liquid 3 in the liquid storage chamber 11.

[0120] The electrical connection component 2 may include a base 21 and electrical connection terminals 22. The base 21 is connected to the liquid storage component 1, and the electrical connection terminals 22 are connected to the side of the base 21 facing away from the liquid storage component 1. The base 21 may be a plate-like structure, with the side of the base 21 facing the liquid storage chamber 11 being a conductive surface 23. The conductive surface 23 of the base 21 is fixedly connected to the adhesive mounting surface 16. The conductive surface 23 of the base 21 (i.e., the side of the base 21 facing away from the electrical connection terminals 22) constitutes the first portion of the electrical connection component 2. The end of the electrical connection terminal 22 facing away from the base 21 is used to electrically connect to the measurement host 8. The end of the electrical connection terminal 22 facing away from the base 21 forms the second portion of the electrical connection component 2.

[0121] In the use state (when the liquid storage component 1 is deformed), the straight-line distance between the conductive surface 23 and the contact surface 12 is L1; in the natural state (when the liquid storage component 1 is not deformed), the straight-line distance between the conductive surface 23 and the contact surface 12 is L2, and L1<L2; in the use state, the conductive surface 23 achieves electrical conduction with the biological surface 4 through the conductive liquid 3 in the liquid storage cavity 11.

[0122] The base 21 may be a circular plate structure, and the liquid storage component 1 may be a circular bowl-shaped structure. The base 21 and the liquid storage component 1 are connected to form a circular flat structure.

[0123] The base 21 and the electrical connection terminals 22 are both conductive structures, such as being made of a conductive metal. The base 21 and the electrical connection terminals 22 can be an integrated structure, or they can be secured together by threading, welding, or snapping. The electrical connection terminals 22, the base 21, the conductive liquid 3 in the liquid storage chamber 11, the conductive liquid 3 in the liquid discharge channel 13, the discharged conductive liquid 3, and the biological surface 4 are sequentially connected in series to form an electrical connection.

[0124] In other embodiments, the electrical connection component 2 may also include a substrate 21 and an electrical connection wire. The electrical connection wire may be used instead of the electrical connection terminal 22 to achieve electrical connection between the electrical connection component 2 and the measurement host 8 .

[0125] In this embodiment, the measuring electrode is initially in two structures, and the two structures can be stored and transported separately; when the measuring electrode is used, the seal 6 is torn off to organize the two independent structures together to form a complete measuring electrode. After the measuring electrode is assembled, since the electrical connection component 2 contacts the biological surface 4 through the liquid storage component 1, the conductive liquid 3 can be stored in the liquid storage component 1, and the liquid storage component 1 also has a contact surface 12 in contact with the biological surface 4, and the contact surface 12 has a liquid discharge channel 13. The liquid storage component 1 has a deformable structure, and the liquid storage component 1 can discharge the conductive liquid 3 by deformation. The conductive liquid 3 can be connected between the biological surface 4 and the contact surface 12, so that during the measurement process, the conductive liquid 3 in the liquid storage chamber 11 can be electrically connected to the biological surface 4 through the discharged conductive liquid 3; and the electrical connection component 2 has a first part electrically connected to the conductive liquid 3 in the liquid storage chamber 11, so that During the measurement process, the electrical connection component 2 can form an electrical connection with the biological surface 4 through the conductive liquid 3 in the liquid storage chamber 11 and the discharged conductive liquid 3. The conductive liquid 3 can pass through the hair on the biological surface 4 and electrically connect with the skin of the biological surface 4, forming a stable electrical connection. Even if the biological body moves during the measurement process, the conductive liquid 3 forms a flexible electrical connection with a certain degree of deformation and can achieve large-area contact with the biological surface 4, ensuring that the electrical connection component always maintains an electrical connection with the skin of the biological surface 4. Moreover, the conductive liquid 3 is used to achieve the electrical connection, and after the measurement is completed, the conductive liquid 3 can be wiped off, without causing discomfort to the biological body. In addition, the split-type measurement electrodes facilitate the transportation and storage of the measurement electrodes.

[0126] In this embodiment, the measuring electrode can be a disposable measuring electrode, pre-stored with conductive liquid 3, without a liquid filling port. In other embodiments, the measuring electrode may not be pre-stored with conductive liquid 3. Before use, after removing the seal 6, conductive liquid 3 can be added to the liquid storage chamber 11 through the connecting channel 161. In other embodiments, the measuring electrode can be a reusable measuring electrode. After removing the electrical connection component 2, conductive liquid 3 can be added to the liquid storage chamber 11 through the connecting channel 161 for repeated use.

[0127] In one embodiment, the measuring electrode may not include the seal 6. The liquid storage component 1 and the electrical connection component 2 are fixedly connected, forming an integrated structure with the liquid storage component 1. The base 21 of the electrical connection component 2 is fixed to the upper cover 1b by bonding or other means. The base 21 is electrically connected to the conductive liquid 3 in the liquid storage chamber 11 via the connection channel 161 of the upper cover 1b. The integrated structure of the liquid storage component 1 and the electrical connection component 2 allows for direct use without the need for assembly.

[0128] In one embodiment, the measuring electrode may also not include the seal 6 and upper cover 1b. The liquid storage component 1 and the electrical connection component 2 are fixedly connected, forming an integrated structure with the liquid storage component 1. The base 21 of the electrical connection component 2 is fixed to the upper end of the liquid storage cup 1a by bonding or other means. The base 21 and the liquid storage cup 1a enclose a liquid storage cavity 11, and the base 21 is directly electrically connected to the conductive liquid 3 within the liquid storage cavity 11. The integrated structure of the liquid storage component 1 and electrical connection component 2 allows for direct use without the need for assembly.

[0129] Referring to Figures 15 to 17 , in one embodiment, a portion of the electrical connection component 2 can extend into the liquid storage chamber 11. For example, the upper end of the liquid storage component 1 is not provided with a mounting opening 14, and the upper end of the liquid storage component 1 is closed, that is, the liquid storage component 1 itself encloses the liquid storage chamber 11. The electrical connection component 2 is located at the upper end of the liquid storage component 1, and the lower end of the electrical connection component 2 extends through the liquid storage component 1 into the liquid storage chamber 11. The conductive surface 23 of the electrical connection component 2 extends into the liquid storage chamber 11, thereby enabling communication between the electrical connection component 2 and the conductive liquid 3 in the liquid storage chamber 11.

[0130] Specifically, the liquid storage component 1 includes a liquid storage cup 1a, an upper cover 1b, and a lower cover 1c. The liquid storage cup 1a is an annular sponge structure that can be compressed and deformed in the axial direction (upward and downward). The upper cover 1b is fixed to the upper end surface of the liquid storage cup 1a and has a mounting hole 17 in the middle. The lower cover 1c is fixed to the lower end surface of the liquid storage cup 1a and has multiple drainage channels 13 (drainage holes) in the lower cover 1c. The liquid storage cup 1a, upper cover 1b, and lower cover 1c enclose a liquid storage chamber 11, which can store the conductive liquid 3.

[0131] The electrical connection component 2 may include an upper terminal 2a and a lower terminal 2b. The upper end of the upper terminal 2a has a spherical structure, and the lower end of the upper terminal 2a has a trumpet-shaped structure. The outer diameter of the trumpet-shaped structure at the lower end of the upper terminal 2a is larger than the diameter of the mounting hole 17, so that the upper terminal 2a can be fixed to the upper cover 1b to block the mounting hole 17. The upper terminal 2a has a mounting hole extending upward from the bottom surface. The lower terminal 2b may have an inverted T-shaped structure. The lower terminal 2b passes through the mounting hole 17 from the inside of the upper cover 1b and connects to the mounting hole of the upper terminal 2a. The upper and lower terminals 2a and 2b may be connected by a threaded connection or a snap-on connection. Both the upper and lower terminals 2a and 2b are conductive structures. The lower surface of the lower terminal 2b forms a conductive surface 23. The conductive surface 23 is located within the liquid storage chamber 11 and can connect to the conductive liquid 3 in the liquid storage chamber 11.

[0132] The liquid storage cup 1a, the upper cover 1b and the lower cover 1c can be insulating non-conductive structures, and the electrical connection component 2 can be electrically connected to the biological surface 4 through the conductive surface 23, the conductive liquid 3 in the liquid storage cavity 11 and the discharged conductive liquid 3 in sequence.

[0133] The liquid storage component 1 may also include a lower cover sticker 1d, which may be a release paper. This sticker 1d is attached to the bottom surface (contact surface 12) of the lower cover 1c, sealing the drainage channel 13 and facilitating the sealed storage of the measuring electrodes. When the measuring electrodes are needed, the sticker 1d is removed and the liquid storage component 1 is placed against the biological surface 4.

[0134] Please refer to Figure 18. In one embodiment, the upper end of the liquid storage component 1 is not provided with a mounting opening 14. The upper end of the liquid storage component 1 is closed, that is, the liquid storage component 1 itself encloses a liquid storage cavity 11. The liquid storage component 1 is a conductive structure, and the electrical connection component 2 is fixed to the upper end of the liquid storage component 1. The electrical connection component 2 is electrically connected to the biological surface 4 through the conductive liquid storage component 1. After the liquid storage component 1 is squeezed, the conductive liquid 3 is discharged from the lower end of the liquid storage component 1. The electrical connection component 2 can also be electrically connected to the biological surface 4 through the liquid storage component 1 and the conductive liquid 3 in sequence. That is, the electrical connection component 2 can be electrically connected to the biological surface 4 through two conductive paths, which can also improve the stability of the electrical connection with the biological surface 4.

[0135] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art can make several simple deductions, modifications or substitutions based on the concept of the present invention.
