As shown in fig. 1-2, anelectrode 100 for collecting bioelectrical signals of a human body or an animal according to an embodiment of the present invention includes an indwellingportion 10, a conductingportion 20, and a limitingportion 30, wherein the indwellingportion 10 is configured to penetrate through the skin of the human body or the animal, at least a portion of the indwellingportion 10 is placed in the skin of the human body or the animal to collect bioelectrical signals of the human body or the animal, and the conductingportion 20 is configured to transmit the bioelectrical signals collected by the indwellingportion 10; theindwelling part 10 comprises afirst end part 111 and asecond end part 121 which are oppositely arranged, the conductingpart 20 comprises athird end part 21 and afourth end part 22 which are oppositely arranged, thethird end part 21 and thesecond end part 121 are electrically connected, and theelectrode 100 is arranged in the skin of the human body or the animal from thefirst end part 111; theposition limiting part 30 is protruded from the outer surface of thesecond end part 121, so as to limit the position of the conductingpart 20 outside the skin of the human body or the animal. It is understood that in other embodiments, the position-limitingportion 30 protrudes from the outer surface of thethird end portion 21, or a portion of the position-limitingportion 30 protrudes from the outer surface of thesecond end portion 121, and another portion of the position-limitingportion 30 protrudes from the outer surface of thethird end portion 21.

When theelectrode 100 is used, an operator holds thelimiting part 30 and injects theretention part 10 into the skin from thefirst end part 111 in an inclined mode when an animal is in an anesthesia state, and thelimiting part 30 is convexly arranged on the outer surface of thesecond end part 121, namely, the size of thelimiting part 30 is larger than that of theretention part 10 along the radial direction of theelectrode 100, so that theelectrode 100 cannot continuously penetrate into the skin when being injected to the limitingpart 30, and the limitingpart 30 is positioned outside the skin; at this time, theelectrode 100 can be fixed by winding a medical adhesive tape, the limitingpart 30 is fixed outside the skin, and the indwellingpart 10 is left under the skin; after theelectrode 100 is fixed, the conductingpart 20 is electrically connected with thelead wire 300, so that theelectrode 100 is electrically connected with the physiological parameter monitoring equipment, and the bioelectric signal acquired by theelectrode 100 is transmitted to the physiological parameter monitoring equipment through the conductingpart 20 and the lead wire in sequence.

By adopting the technical scheme, at least part of the indwellingpart 10 is indwelling in the subcutaneous part to collect the bioelectricity signal, the electrode clamp is not needed to clamp the skin of the animal to collect the bioelectricity signal, so that the problem of insufficient or overlarge clamping force does not exist, only theindwelling part 10 of theelectrode 100 needs to be injected into the skin, and at least part of the indwellingpart 10 is indwelling in the subcutaneous part, and the applicability of theelectrode 100 is wide. In addition, according to theelectrode 100 provided by the embodiment of the utility model, the limitingpart 30 is arranged, so that theconduction part 20 is positioned outside the skin, the situation that thewhole electrode 100 is injected into the skin and is inconvenient to take out can be prevented, and theelectrode 100 is wound and fixed through common medical adhesive tapes, so that theelectrode 100 is convenient and quick to fix.

Referring to fig. 1-2, the indwellingportion 10 includes aneedle 11 and aneedle 12 connected to theneedle 11, wherein an end of theneedle 11 away from theneedle 12 forms afirst end 111, and an end of theneedle 12 away from theneedle 11 forms asecond end 121; theneedle body 12 has a hardness less than or equal to that of theneedle tip 11, and theneedle body 12 is a member made of a conductive material. By providing theneedle body 12 as a member made of a conductive material, theneedle body 12 has conductivity. In this embodiment, theneedle body 12 collects the bioelectric signal and transmits the collected bioelectric signal to the conductingportion 20, and theneedle body 12 may be partially or entirely placed under the skin. In practice, the hardness of theneedle 11 is similar to that of a rigid metal, so that theneedle 11 can penetrate the skin of an animal without being bent. The hardness of theneedle body 12 is about the hardness of semi-rigid metal, so that theneedle body 12 has certain flexibility and certain hardness, when theneedle body 12 is kept in the skin of an animal, theneedle body 12 cannot cause secondary damage to the animal in the moving process of the animal, for example, when the animal needs to be washed teeth after sterilization operation, in the process of moving the animal from an operation area to a tooth washing area, even if the skin with theneedle body 12 kept in the skin subcutaneously is bent or forms a fold, theneedle body 12 can be correspondingly bent along with the bending trend of the skin, and cannot cause damage to the animal; the hardness of theneedle body 12 enables the operator to hold the limitingpart 30 to push theelectrode 100 after theneedle 11 is inserted into the skin, so that theneedle body 12 can be inserted into the skin without being bent, thereby realizing that theneedle body 12 is left under the skin.

In one embodiment, theneedle 11 is a member made of a conductive material. In this arrangement, theneedle 11 is electrically conductive, and theneedle 11 can also be used to collect bioelectrical signals. It will be appreciated that in other embodiments it is also possible for theneedle 11 to be a component made of an insulating material. In this arrangement, theneedle 11 has no conductivity, and at this time, theneedle 11 cannot collect the bioelectric signal, and at least a part of theneedle body 12 needs to be inserted into the skin and left under the skin. In practical applications, there is no limitation on whether theneedle 11 has conductivity, and at least a portion of theneedle body 12 needs to be inserted into the skin and left under the skin.

In one embodiment, theneedle body 12 has a length greater than the length of theneedle tip 11. In practice, the length of theneedle body 12 is set long enough to increase the subcutaneous contact area of theneedle body 12 for more efficient acquisition of bioelectrical signals.

Referring to fig. 1, theneedle 11 is tapered, and the radial dimension of theneedle 11 gradually decreases from theneedle 12 to a direction away from theneedle 12. By providing theneedle 11 with a tapered shape, and the radial dimension of theneedle 11 gradually decreases from theneedle body 12 toward the direction away from theneedle body 12, that is, the radial dimension of the end of theneedle 11 away from theneedle body 12 is small, thereby facilitating the penetration of theneedle 11 through the skin. It will be appreciated that in other embodiments, referring to fig. 3, it is also possible for the end of theneedle 11 remote from theneedle body 12 to be tapered.

Referring to fig. 1, the radial dimension of theneedle body 12 is larger than the radial dimension of the end of theneedle 11 near theneedle body 12. By increasing the radial dimension of theneedle body 12 and thus increasing the subcutaneous contact area of theneedle body 12, the bioelectric signal is acquired more efficiently. As a preferred embodiment, there is a smooth transition between theneedle 11 and theneedle body 12. It will be appreciated that in other embodiments it is also possible that the radial dimension of theneedle body 12 is equal to the radial dimension of the end of theneedle 11 close to theneedle body 12.

For example, the limitingportion 30 includes two wing-shaped members, and the two wing-shaped members are symmetrically disposed on two opposite sides of thesecond end portion 121.

In one embodiment, the outer contour of thestop portion 30 is smoothly curved. In a preferred embodiment, the limitingportion 30 extends along thesecond end portion 121 toward thethird end portion 21 with a tendency of gradually increasing and then gradually decreasing in radial dimension.
