Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a low-frequency direct current stimulation multi-point treatment electrode patch for patients with facial paralysis. Background Art

[0002] After facial nerve injury, patients are prone to symptoms such as facial motor dysfunction, which can cause facial muscle paralysis in severe cases, seriously affecting the patient's quality of life. Depending on the condition of facial nerve injury, patients can receive conservative treatment or nerve repair surgery, but nerve regeneration and functional recovery after treatment are slow and often incomplete. According to previous basic research and clinical practice experience, auxiliary functional rehabilitation training is very important on the basis of conservative treatment or nerve repair surgery. Among them, effective neuromuscular electrical stimulation therapy can not only promote nerve fiber regeneration but also delay muscle atrophy and increase the degree of functional recovery of paralyzed muscles. Low-frequency direct current stimulation for the treatment of neuromuscular injury has been widely used in clinical practice and has a good therapeutic effect.

[0003] Traditional low-frequency direct current stimulation therapy is to use an electrical stimulation therapy device to perform electrical stimulation therapy on patients through wires and skin patches. The quality and shape of the electrical stimulation skin patch, which is the main consumable, are very important and determine the effect and efficiency of the treatment. At present, the electrode patches used in clinical medical applications are mostly used for muscles with relatively large areas, such as muscles of the trunk and limbs, spine or joints, and most of them are round, square or irregular in shape. However, according to clinical practice, since facial muscles are relatively small and complex in direction, these existing electrode patches cannot fit well with the muscles of the relevant facial paralysis, especially for regional muscles such as the orbicularis oculi and oris oris, which brings inconvenience to the treatment and reduces the treatment effect and efficiency.

[0004] Therefore, a kind of improved electrode patch applicable to patients with facial paralysis is needed. Summary of the invention

[0005] The first object of the present invention is to provide an electrode patch suitable for patients with facial paralysis.

[0006] The second object of the present invention is to provide an electrode patch set for patients with facial paralysis.

[0007] To achieve the above first object, the present invention provides the following technical solutions:

[0008] An electrode patch applicable to patients with facial paralysis, comprising: a patch body, a non-woven fabric and two electrode wires;

[0009] The patch body comprises a first conductive silicone region, a second conductive silicone region and an insulating region between the two conductive silicone regions, wherein the conductive silicone region comprises silicone and conductive particles distributed in the silicone, and an electrode contact is respectively arranged in each of the conductive silicone regions;

[0010] The patch body is covered with non-woven fabric;

[0011] One end of the two electrode wires is connected to an electrode contact point respectively, and the other end is provided with a wire connector.

[0012] Furthermore, the patch body is in a semi-fan-shaped shape, and the first conductive silicone area and the second conductive silicone area are respectively located in the opposite arc part and the straight line part. In this case, the electrode patch is a semi-fan-shaped electrode patch, which is suitable for the frontalis area.

[0013] Furthermore, the patch body is in a crescent shape, and the first conductive silicone area and the second conductive silicone area are respectively located at two opposite ends. At this time, the electrode patch is a crescent-shaped electrode patch, which is suitable for the orbicularis oculi area and the orbicularis oris area. Preferably, the crescent-shaped electrode patch is divided into two types, one is a crescent-shaped electrode patch for the eye that fits the orbicularis oculi area, and the other is a crescent-shaped electrode patch for the mouth that fits the orbicularis oris area; the first electrode contact of the crescent-shaped electrode patch for the eye is located in the upper half of the elliptical orbicularis oculi muscle, and the second electrode contact is located in the lower half of the elliptical orbicularis oculi muscle; the first electrode contact of the crescent-shaped electrode patch for the mouth is located in the upper half of the elliptical orbicularis oris muscle, and the second electrode contact is located in the lower half of the elliptical orbicularis oris muscle.

[0014] Furthermore, the patch body is elliptical in shape, and the first conductive silicone area and the second conductive silicone area are respectively located at two opposite ends along the long axis. In this case, the electrode patch is an elliptical electrode patch, which is suitable for the zygomatic major muscle area.

[0015] Furthermore, the two electrode contacts on each electrode patch are respectively located at the starting point and the end point of the muscle course.

[0016] Furthermore, the length of the insulating area is 1.5 cm.

[0017] Furthermore, the distance between two electrode contacts on each electrode patch is 3.5 cm.

[0018] Furthermore, the electrode wire is a metal wire.

[0019] Furthermore, the conductive particles are conductive particles such as silver-coated copper powder, nickel-coated graphite powder, etc.

[0020] To achieve the above second purpose, the present invention provides the following technical solutions:

[0021] An electrode patch group for patients with facial paralysis comprises at least two of the aforementioned electrode patches; each electrode patch comprises: a patch body, a non-woven fabric and two electrode wires; the patch body comprises a first conductive silicone area, a second conductive silicone area and an insulating area located between the two conductive silicone areas, the conductive silicone area comprises silicone and conductive particles distributed in the silicone, and an electrode contact is respectively arranged in each of the conductive silicone areas; the patch body is covered with non-woven fabric; one end of the two electrode wires is respectively connected to an electrode contact, and the other end is provided with a wire connector.

[0022] Furthermore, the electrode patch group includes a semi-fan-shaped electrode patch, a crescent-shaped electrode patch and an elliptical electrode patch; the patch body of the semi-fan-shaped electrode patch is a semi-fan-shaped shape; the patch body of the crescent-shaped electrode patch is a crescent-shaped shape; and the patch body of the elliptical electrode patch is an elliptical shape.

[0023] Furthermore, the electrode patch group includes a semi-fan-shaped electrode patch, four crescent-shaped electrode patches and two elliptical electrode patches.

[0024] Furthermore, the electrode patch group includes a semi-fan-shaped electrode patch, two crescent-shaped electrode patches for eyes, two crescent-shaped electrode patches for mouth, and two elliptical electrode patches.

[0025] The present invention has the following advantages:

[0026] 1. The electrode patch of the present invention has low cost, high performance, and is easy to use. It is a disposable consumable. When used, the electrode patch can enable the muscles to produce better contraction and relaxation effects when receiving external low-frequency electrical stimulation, thereby improving the effect and efficiency of low-frequency direct current stimulation treatment for patients with facial paralysis.

[0027] 2. The electrode patch set of the present invention includes several electrode patches that can be used for four muscle areas of the face. Electrode patches of different shapes can be selected for targeted treatment according to the needs of the patient's facial paralysis muscles, and can also reduce muscle fatigue caused by long-term stimulation of regional muscles.

[0034] Example 1

[0035] like Figure 1 and 2 As shown, it is a structural schematic diagram of a semi-sector electrode patch applicable to patients with facial paralysis of the present invention. The electrode patch is a bipolar patch, comprising: a patch body, a non-woven fabric 6, a first electrode wire 41 (a metal wire), and a second electrode wire 42. The patch body is in a semi-sector shape, including a first conductive silicone area 21 (composed of silicone and conductive particles 2 distributed in the silicone) located on one side of the arc portion, a second conductive silicone area 22 located on one side of the straight portion, and an insulating area 1 located between the two conductive silicone areas. The first conductive silicone area 21 and the second conductive silicone area 22 are connected to each other through contact between the conductive particles 2 to achieve good conductive properties. The conductive particles 2 can be conductive particles such as silver-coated copper powder and nickel-coated graphite powder. The length L1 of the insulating area 1 is 1.5 cm. A first electrode contact 31 is provided in the first conductive silicone area 21, and a second electrode contact 32 is provided in the second conductive silicone area 22. The distance L2 between the first electrode contact 31 and the second electrode contact 32 is 3.5 cm. One end of the first electrode wire 41 is connected to the first electrode contact 31, and the other end is provided with a first wire connector 51. One end of the second electrode wire 42 is connected to the second electrode contact 32, and the other end is provided with a second wire connector 52. The patch body is covered with a non-woven fabric 6. The non-woven fabric 6 can be designed in different shapes according to the muscle path. The electrode patch is suitable for the frontalis muscle area.

[0036] Example 2

[0037] like Figure 3 , which is a schematic diagram of the structure of a crescent-shaped electrode patch applicable to patients with facial paralysis of the present invention. The only difference from Example 1 is that the patch body is in a crescent shape. The first conductive silicone area 21 and the second conductive silicone area 22 are respectively located at the opposite ends of the crescent. The electrode patch is applicable to the orbicularis oculi muscle area and the orbicularis oris muscle area.

[0038] Example 3

[0039] like Figure 4, which is a schematic diagram of the structure of an elliptical electrode patch applicable to patients with facial paralysis according to the present invention. The only difference from Example 1 is that the patch body is elliptical in shape. The first conductive silicone area 21 and the second conductive silicone area 22 are respectively located at two opposite ends along the long axis. The electrode patch is applicable to the zygomatic major muscle area.

[0040] Example 4

[0041] An electrode patch set for patients with facial paralysis is designed according to the different routes of normal human facial muscles, and includes electrode patches located in four muscle areas, specifically: a semi-fan-shaped electrode patch of embodiment 1 attached to the frontalis muscle area, a crescent-shaped electrode patch of embodiment 2 attached to the orbicularis oculi muscle area and the orbicularis oris muscle area, and an elliptical electrode patch of embodiment 3 attached to the zygomatic major muscle area (application schematic diagram as shown in FIG. Figure 5 As shown in the figure). These four parts of the electrode patch can cover the relatively large facial muscles that support the main facial expressions, and can achieve the purpose of better fitting along the muscle course to the face. When used for patients with facial muscle paralysis, the main running area does not change, and this electrode patch group can better fit the paralyzed muscles. The two stimulation ends of each electrode patch are located at the starting point and the end point of the muscle course, and the middle part of the electrode patch is insulated, so that the muscle can produce better contraction and relaxation effects when receiving external low-frequency electrical stimulation.

[0042] According to the needs of clinical low-frequency direct current stimulation treatment for facial paralysis, the electrode patch is directly connected to the machine wire interface through the wire connector to perform electrical stimulation treatment. In order to increase the adhesion and effective conductivity of the electrode patch, when using it, wipe a small amount of medical conductive adhesive coupling agent on the conductive silicone area of ​​each electrode patch to increase the effect and efficiency of the electrode patch.

[0043] Example 5

[0044] An electrode patch set for patients with facial paralysis is similar to Example 4, except that there are two types of crescent-shaped electrode patches, one is a crescent-shaped electrode patch for the eyes that fits the orbicularis oculi muscle area, and the other is a crescent-shaped electrode patch for the mouth that fits the orbicularis oris muscle area. Figure 6 As shown in . The shape of the crescent-shaped electrode patch for the eye satisfies that the first electrode contact 31 is located at the upper half of the elliptical orbicularis oculi muscle, and the second electrode contact 32 is located at the lower half of the elliptical orbicularis oculi muscle. The shape of the crescent-shaped electrode patch for the mouth satisfies that the first electrode contact 31 is located at the upper half of the elliptical orbicularis oris muscle, and the second electrode contact 32 is located at the lower half of the elliptical orbicularis oris muscle.
