Referring to fig. 1, fig. 1 is a schematic structural diagram of a medical electrode 100 according to an embodiment of the present application.

Embodiments of the present application provide a medical electrode 100. The medical electrode 100 includes a connector 10, a wire organizer 20, N lead wires 30, and N electrodes 40, each lead wire 30 includes a first end 31 and a second end 32, the N electrodes 40 are electrically connected to the first ends 31 of the N lead wires 30 in a one-to-one correspondence, and the second ends 32 of the N lead wires 30 are electrically connected to the connector 10, wherein N is an integer greater than 1. The N lead wires 30 pass through the wire organizer 20, and the wire organizer 20 can slide with respect to the N lead wires 30.

It can be appreciated that the medical electrode 100 of the present application makes the wire arranging device 20 slide relatively to the N lead wires 30 by passing the N lead wires 30 through the wire arranging device 20, thereby ensuring that the wire harness of the medical electrode 100 is orderly arranged, avoiding the mutual winding between the plurality of lead wires 30, making the lead wires 30 continuously pulled, avoiding the damage of the lead wires 30, affecting the signal acquisition quality, and shortening the service life of the medical electrode 100.

In some embodiments, the connector 10 may include an interface 11, the interface 11 being for electrically connecting to an external device (not shown) of the medical electrode 100, the external device being for controlling the medical electrode 100 to perform signal acquisition operations. The Type of the interface 11 of the connector 10 includes a plurality of types, and in this embodiment, the Type of the interface 11 of the connector 10 is a USB Type-C interface. Of course, in other embodiments, the interface 11 of the connector 10 may be a mini high-definition multimedia interface or a high-definition multimedia interface, which is not limited in this application.

In some embodiments, the lead wire 30 may include a wire core and a shielding layer surrounding the wire core, one end of the wire core being electrically connected to the electrode 40, and the other end of the wire core being electrically connected to the connector 10. In this embodiment, the second end 32 of the lead wire 30 is connected to the connector 10 by welding. Of course, in other embodiments, the lead wire 30 may be connected to the connector 10 by other connection methods, which are not limited in this application.

It will be appreciated that the lead wires 30 of the present application are formed by wrapping the shielding layer around the outside of the wire core such that each lead wire 30 is independent of the other. When one of the lead wires 30 of the medical electrode 100 fails, it does not affect the operation of the remaining lead wires 30, effectively improving the service life of the medical electrode 100. Meanwhile, each lead wire 30 is mutually independent, so that each electrode 40 can be controlled to acquire signals at different measuring positions according to requirements, and the signal acquisition efficiency can be improved.

In this embodiment, the wire organizer 20 is made of plastic. Of course, in other embodiments, the wire organizer 20 may also be made of metal, and the material of the wire organizer 20 is not limited in this application.

Referring to fig. 1, 2, 3A and 3B, fig. 2 is a schematic structural view of the first wire organizer 21 of the medical electrode 100 shown in fig. 1. Fig. 3A is a schematic diagram of the first wire organizer 21 shown in fig. 2 in another direction. Fig. 3B is a schematic structural view of the first wire organizer 21 shown in fig. 2 in an opposite direction to the other direction.

In the present embodiment, the wire organizer 20 includes a first wire organizer 21. The first wire organizer 21 includes a first end surface 211 and a second end surface 212, the first end surface 211 being disposed toward the connector 10, the second end surface 212 being disposed toward the electrode 40, and the first wire organizer 21 being slidable with respect to the N lead wires 30. The area enclosed by the N lead wires 30 passing through the first end surface 211 is a first area 214, and the area enclosed by the N lead wires passing through the second end surface 212 is a second area 215, wherein the first area 214 is smaller than the second area 215.

The second ends 32 of the N lead wires 30 pass through the second end surface 212 of the first wire organizer 21, and then pass through the first end surface 211 of the first wire organizer 21 to be connected to the connector 10, and the first wire organizer 21 combs the N lead wires 30 by sliding on the N lead wires 30. It will be appreciated that since the area of the first area 214 is smaller than the area of the second area 215, when the N lead wires 30 sequentially pass through the second end face 212 and the first end face 211, the N lead wires 30 are first bundled at the second end face 212 so that the wire bundles are arranged in order, and then further bundled at the first end face 211 so that the N lead wires 30 can be further gathered and then electrically connected to the connector 10. In other words, after the N lead wires 30 pass through the first end surface 211, the overall sectional area is smaller, and the harness arrangement is more ordered, which is advantageous for miniaturization of the entire medical electrode 100.

Referring to fig. 1, fig. 2, fig. 3A and fig. 4, fig. 4 is a schematic structural diagram of another embodiment of the first wire organizer 21 shown in fig. 3A in another direction.

In the present embodiment, the first wire organizer 21 includes N through holes 213, and each of the N through holes 213 penetrates from the first end surface 211 to the second end surface 212. The second ends 32 of the N lead wires 30 pass through the N through holes 213 one by one from the first end surface 211, and then pass through the second end surface 212 and are electrically connected to the connector 10.

It can be appreciated that the N lead wires 30 pass through the N through holes 213 in a one-to-one correspondence manner, so that each lead wire 30 can be separated from other lead wires 30 by the through holes 213, and the N lead wires 30 are independent from each other, so that the arrangement is clearer and more ordered. When one of the electrodes 40 or the lead wires 30 malfunctions, since the lead wires 30 are independent of each other and the electrodes 40 are independent of each other, the malfunction can be more rapidly discharged and the maintenance or the component replacement of the medical electrode 100 can be performed.

In some embodiments, the first wire organizer 21 may further include only one through hole 213, and the second ends 32 of the n lead wires 30 pass through the through hole 213 from the first end surface 211, then pass through the second end surface 212, and are electrically connected to the connector 10. Of course, in other embodiments, two or more through holes 213 may be provided, and the specific number of through holes 213 is not limited in this application.

Referring to fig. 1 and 5 together, fig. 5 is a schematic diagram of a second wire organizer 22 of the medical electrode 100 shown in fig. 1.

In this embodiment, the wire organizer 20 may further include a second wire organizer 22, and the first wire organizer 21 is located between the second wire organizer 22 and the connector 10. The second-type wire organizer 22 includes a third end surface 221 and a fourth end surface 222, the third end surface 221 being disposed toward the first-type wire organizer 21, the fourth end surface 222 being disposed toward the electrode 40, the second-type wire organizer 22 being capable of sliding with respect to the N lead wires 30. The area enclosed by the N lead wires 30 passing through the third end surface 221 is a third area, the area enclosed by the N lead wires passing through the fourth end surface 222 is a fourth area, and the third area is equal to the fourth area.

In some embodiments, the area of the third area is equal to the area of the first area 214 of the first wire organizer 21 to ensure that the second wire organizer 22 can slide smoothly over the lead wires 30. Of course, in other embodiments, the area of the third area may also be unequal to the area of the first area 214.

In this embodiment, the second ends 32 of the N lead wires 30 sequentially pass through the fourth end face 222 and the third end face 221 of the second wire organizer 22, then pass through the second end face 212 and the first end face 211 of the first wire organizer 21, and finally are electrically connected to the connector 10. It can be understood that the medical electrode 100 of the present application is provided with the first wire sorter 21 and the second wire sorter 22 at the same time, and the N lead wires 30 are combed and bundled by sliding the first wire sorter 21 and the second wire sorter 22 relative to the lead wires 30, so that the N lead wires 30 are orderly arranged with each other.

When the lead wires 30 are excessively long, one of the wire managers 20 (i.e., the first-type wire manager 21) can act only on the portions of the N lead wires 30, and the portions of the N lead wires 30 are arranged in order, and the portions of the N lead wires 30 distant from the first-type wire manager 21 are still in an unordered or entangled state. And the first wire sorter 21 and the second wire sorter 22 are simultaneously arranged, so that the second wire sorter 22 can be slid to the part of the N lead wires 30 far away from the first wire sorter 21 so as to comb the wire harness of the part of the medical electrode 100. In other words, the second wire organizer 22 is used for assisting the first wire organizer 21 to comb the lead wires 30, and through the combined action of the first wire organizer 21 and the second wire organizer 22, the medical electrode 100 of the present application can maintain the N lead wires 30 in an orderly arranged state even if the lead wires 30 are longer, thereby avoiding the damage caused by the mutual winding between the lead wires 30, and being beneficial to improving the service life of the medical electrode 100.

Of course, in other embodiments, the second wire organizer 22 of the medical electrode 100 may be provided in a plurality according to the specific length and requirement of the lead wires 30, and the number of the second wire organizer 22 is not limited in this application.

Referring to fig. 1 and 6 together, fig. 6 is a schematic cross-sectional view of the electrode 40 of the medical electrode 100 shown in fig. 1 in the B-B direction.

In this embodiment, each electrode 40 includes an insulating portion 41 and a conductive portion 42, the insulating portion 41 is provided with a groove 411, and an opening of the groove 411 is located on an outer surface of the insulating portion 41. A portion of the conductive portion 42 is embedded in the insulating portion 41, a portion of the conductive portion 42 is located in the recess 411, and the conductive portion 42 of each electrode 40 is electrically connected to the first ends 31 of the N conductive wires 30 in a one-to-one correspondence.

In some embodiments, the conductive portion 42 may include a first portion 421 and a second portion 422, the second portion 422 surrounding the first portion 421, the second portion 422 being electrically connected to the first end 31 of the lead wire 30. In some embodiments, the material of the first portion 421 is copper or silver, the material of the second portion 422 is silver chloride, or the first portion 421 and the second portion 422 may be made of metal or nonmetal that is electrically conductive, such as gold, copper, silver, etc., and the material of the conductive portion 42 is not limited in this application.

In this embodiment, the groove 411 is filled with a medical conductive paste, and the medical conductive paste is used to wrap a part of the conductive portion 42 in the groove 411, so that the conductive portion 42 can indirectly contact the signal acquisition position and acquire the signal. When the medical electrode 100 is applied to human skin to collect electromyographic signals, the medical conductive paste is filled in the groove 411, so that the conductive part 42 cannot be in direct contact with the human skin, and allergic reaction of certain people due to long-time contact of metal and the skin is avoided.

Through experiments, when the medical electrode 100 is used for electromyographic signal acquisition, the medical conductive paste is filled between the skin of a human body and the conductive part 42 of the electrode 40, and compared with the electromyographic signal acquired when the conductive part 42 of the electrode 40 is directly contacted with the skin without the medical conductive paste, the electromyographic signal acquisition is more stable and the signal quality is better. Of course, in other embodiments, the recess 411 may be filled with other conductive materials, which is not limited in this application.

It will be appreciated that the medical electrode 100 of the present application allows each electrode 40 to be independent of the other by providing the insulating portion 41 outside the conductive portion 42 of the electrode 40. Meanwhile, the conductive parts 42 of each electrode 40 are electrically connected to the N lead wires 30 in a one-to-one correspondence, so that each electrode 40 can be individually controlled, and thus the plurality of electrodes 40 can be densely or dispersedly arranged at different signal acquisition positions according to the requirements, and the intervals between the electrodes 40 can be adjusted.

In order to meet the requirement that more dense electrodes are arranged on the surface of skin with a certain area, a plurality of electrodes are fixed on the same substrate according to a certain arrangement method to manufacture electrode plates, and the electrode plates are adhered to the surface of human skin to collect electromyographic signals of the skin. However, because the fluctuation degree of the skin is different when different parts of the human body act, the fluctuation of the skin can drive partial electrodes of the electrode plates stuck on the surface of the skin to fluctuate, so that the electrodes at other positions on the same substrate are shifted or lead is fallen, the electrode plates cannot keep good contact with the skin, and the accuracy of signal acquisition is affected.

When the medical electrode 100 of the present application performs signal acquisition, since the electrodes 40 are mutually independent, and each electrode 40 is electrically connected to each lead wire 30 in a one-to-one correspondence, each electrode 40 can be flexibly arranged at different positions of the skin according to the needs. When the skin undulates, since the electrodes 40 are independent of each other, the rest of the electrodes 40 are not affected when one electrode 40 undulates with the skin. In other words, even if the skin fluctuates during measurement, the electrode 40 of the medical electrode 100 of the present application can be kept in good contact with the skin, which is advantageous for obtaining a more stable electromyographic signal. Meanwhile, the medical conductive paste is filled in the groove 411 of the electrode 40, and can adapt to the fluctuation of the skin and generate corresponding deformation because the medical conductive paste is paste, so that the contact between the electrode 40 and the skin is more stable, and the quality of signal acquisition is improved.

Referring back to fig. 6, in the present embodiment, the conductive portion 42 includes a first surface 421, the first surface 421 faces the opening of the recess 411, and the distance between the first surface 421 and the opening of the recess 411 is in the range of 0.1 mm to 3 mm. It is understood that the signal quality measured when the medical conductive paste is filled in the recess 411, the thickness between the conductive part 42 and the skin is between 0.1 mm and 3 mm is the best.

In some embodiments, the insulating portion 41 may include a base portion 411 and an injection molded portion 412, the injection molded portion 412 being connected to the base portion 411, the recess 411 being located in the base portion 411. A part of the conductive portion 42 is embedded in the base part 411 and a part is embedded in the injection part 412. It will be appreciated that after the conductive portion 42 is embedded in the base portion 411, the injection molded portion 412 is connected to the base portion 411 by injection molding, so as to fix the conductive portion 42 to the insulating portion 41. Of course, in other embodiments, the base part 411 and the injection part 412 may be integrally formed, and the base part 411 and the injection part 412 may be formed together by injection molding. The insulating portion 41 is made of a terpolymer (ABS) of three monomers, namely, acrylonitrile, butadiene and styrene. The specific structure and material of the insulating portion 41 are not limited in this application.

In the present embodiment, the size of the insulating portion 41 is in the range of 3 mm to 15 mm, and the size of the conductive portion 42 is in the range of 0.5 mm to 3 mm. It can be appreciated that the electrode 40 of the medical electrode 100 of the present application has a smaller size, and can more densely arrange the electrode 40 on the skin surface with a certain area, which is beneficial to improving the efficiency and quality of signal acquisition.

In some embodiments, each electrode 40 may further include a wire protecting portion 43, where the wire protecting portion 43 is connected to the insulating portion 41, and N lead wires 30 are sleeved in a one-to-one correspondence with the wire protecting portion 43 of each electrode 40. It can be understood that by arranging the wire protecting part 43, the contact part of each lead wire 30 and each electrode 40 can be wrapped by the wire protecting part 43, so that the rigidity and toughness of the lead wire 30 are enhanced, and the lead wire 30 is prevented from being damaged by bending at the contact part of the lead wire 30 and the electrode 40 when the medical electrode 100 works, thereby influencing the quality and accuracy of signal acquisition.

In some embodiments, the surface of the groove 411 of the insulating portion 41 may be further adhered with a medical double sided tape 44, so that the electrode 40 can be adhered to the surface of the skin of the human body through the medical double sided tape 44, so as to collect the electromyographic signals. Of course, in other embodiments, the electrode 40 may be fixed to the surface of the skin of the human body in other manners, and the method for fixing the electrode 40 is not limited in this application.

It should be noted that, under the condition of no conflict, the embodiments and features in the embodiments may be combined with each other, and any combination of features in different embodiments is also within the protection scope of the present application, that is, the above-described embodiments may also be combined arbitrarily according to actual needs.

It should be noted that all the foregoing drawings are exemplary illustrations of the present application, and do not represent actual sizes of products. And the dimensional proportion relation between the components in the drawings is not limited to the actual products of the present application.

The above is only a part of examples and embodiments of the present application, and the scope of the present application is not limited thereto, and any person skilled in the art who is familiar with the technical scope of the present application can easily think about the changes or substitutions, and all the changes or substitutions are covered in the scope of the present application.
