[0002] Facial paralysis caused by tumors, trauma, and other causes is a medical challenge. Currently, in addition to surgical nerve repair, neuromuscular electrical stimulation (also known as "low-frequency pulsed electrotherapy") is a very important treatment option. This therapy stimulates damaged nerves and muscles with low-frequency pulsed currents, inducing passive contraction and thus promoting muscle function and nerve regeneration. However, the facial nerve's target muscles, such as the frontalis, orbicularis oculi, buccinator, and orbicularis oris, have distinct courses, making effective electrical stimulation of these diverse muscles a challenge.

[0003] The stimulation devices currently used in clinical practice are relatively rudimentary, relying primarily on patch designs and lacking specialized tools, making it impossible to precisely stimulate the target muscles. This results in low treatment efficiency and a poor patient experience, causing some patients to lose confidence in continuing treatment, seriously hindering the recovery of facial nerve injuries.

[0004] Based on the above background, a portable device that can accurately stimulate facial nerve muscles is particularly important. Utility Model Content

[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0022] It can be understood by those skilled in the art that, unless specifically stated, the singular forms "a", "an" and "the" used herein include plural forms. It should be further understood that the word "comprise" used in the specification of the present application means that the features, integers, steps, operations, elements and / or components exist, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0023] First embodiment

[0024] In current clinical practice, the facial nerve muscle stimulation device is generally simple and rough, and it is difficult to achieve precise stimulation of the complex muscle group of the face. The following are the problems of the existing device: (1) the current stimulation device relies on standard patch electrodes, and lacks electrode patches specially adapted to facial anatomy, such as for the orbicularis oculi / orbicularis oris muscle (located around the eyes / lips), the current device's electrode patch cannot achieve simultaneous stimulation of the entire muscle area. (2) The electrode patch is attached by the patient himself, and since the patient lacks knowledge of anatomy, if the electrode position is not attached accurately, the expected therapeutic effect cannot be achieved, and even adverse effects may occur. (3) There are many muscles that need to be stimulated during the use of facial paralysis, and 4-5 electrode patches may need to be attached for a single treatment. Repeated attachment can make the patient's experience extremely poor, thus losing confidence in continuing treatment.

[0025] It is in this context that the inventors began to think about how to improve the status quo. After in-depth research, a wearable mask device for facial neuromuscular stimulation based on 3D printing is designed. The main idea is to scan the facial data of patients with facial paralysis, design a mask digitally, and reserve electrode positions according to the running of facial muscles (frontalis muscle, orbicularis oculi muscle, buccinator muscle, and orbicularis oris muscle). The personalized mask device not only can be customized by 3D printing after scanning the patient's facial morphology, but also can accurately cover the key areas of facial neuromuscular. Professional doctors can set electrode pieces in specific areas of the mask (such as frontalis muscle, orbicularis oculi muscle, buccinator muscle, and orbicularis oris muscle), effectively stimulating the frontalis muscle, orbicularis oculi muscle, buccinator muscle, and orbicularis oris muscle. In this way, after the mask and electrode pieces are anchored, the power supply is connected to achieve accurate and efficient stimulation of facial neuromuscular. All electrodes are integrated in a convenient mask, which not only improves comfort but also reduces the risk of skin damage caused by repeated sticking. At the same time, the multi-channel design makes treatment more efficient, greatly saving the patient's time. The specific implementation of the utility model is as follows:

[0026] As shown in Figure 1 The utility model provides a wearable mask device for facial neuromuscular stimulation based on 3D printing, which comprises:

[0027] The mask body is a half mask covering the side of the wearer's facial paralysis. A plurality of positioning holes are arranged on the mask body, and the positioning holes correspond to any facial nerve target muscle area when the mask body is worn. The mask body is internally provided with a plurality of electrode piece assemblies. The connecting lines of the electrode piece assemblies pass through the positioning holes and are connected with the power supply unit to drive the electrode pieces to perform electrical stimulation work.

[0028] The material of the mask body is a hard material, including photosensitive resin, etc. The mask body made of transparent resin by 3D printing has the characteristics of lightweight, ensuring comfort when worn, and maintaining good visual aesthetics.

[0029] Facial paralysis usually affects half of the face, causing dysfunction of related muscles, so targeted treatment is needed. Therefore, the mask body of the device is designed as a half mask, which can cover the left or right side of the wearer's face, and one or more positioning holes corresponding to the facial nerve target muscle area are provided on the mask. Ensure that the electrode pieces can be accurately fixed inside the half mask and connected with the electrotherapy instrument through the positioning holes, thereby effectively driving the electrode pieces to perform electrical stimulation work to promote the rehabilitation of damaged muscles.

[0030] Specifically, the inner side of the mask body conforms to the curved surface of the face, and the mask body is integrally formed. One side of the mask body conforms to the edge of the wearer's face to form a natural contour, ensuring comfort and aesthetics when worn. The other side is a vacant area, which is a normal facial area that does not need to be processed. This not only reduces the weight of the mask, but also avoids unnecessary interference. At the same time, the vacant area of the mask body also includes a facial feature area, which includes the eye, nose, and mouth areas, providing better stability for the mask fixation, so that the electrode sheet can effectively cover the facial muscle area, achieving the best electrical stimulation effect.

[0031] At the same time, the device also includes at least one mask fixing member, which includes a fixing band and a connecting sub-member. The fixing band is connected and fixed through the connecting sub-member located on both sides of the mask body. And the vacant area of the mask body is provided with an extension member, which is connected with the half mask and provided with a connecting sub-member, used for connecting and fixing with the fixing band. For example, the extension member is a sub-member extending from the eye area of the mask body to the vacant area, for example, the extension member is designed similar to one side of glasses, extending from the eye area of the mask body to the vacant area, making it more convenient and comfortable to wear. This structure not only ensures the stability of the mask on the wearer's face, but also allows the user to easily adjust, thereby improving the adaptability and convenience, ensuring the accuracy and effect of electrode stimulation.

[0032] The positioning through hole precisely aligns with the facial nerve target muscle area, ensuring that the facial nerve target muscle area covered by the electrode sheet assembly through the positioning through hole includes key areas such as the frontalis muscle area, the orbicularis oculi muscle area, the buccinator muscle area, and the orbicularis oris muscle area. This design is an innovation of the present scheme. Through face scanning to generate a personalized model, the positioning through hole can be highly matched with the muscle anatomy structure of each patient, thereby achieving higher fit, ensuring precise and effective stimulation of facial nerve muscles.

[0033] In addition, all electrode sheets are integrated in one mask device, greatly improving the convenience of use, avoiding the inconvenience and potential skin damage risk caused by repeated electrode pasting in traditional methods. This integrated design not only simplifies the operation process and improves the efficiency of treatment, but also enhances the wearing comfort. Through multi-channel stimulation, the use process is more efficient, which can better meet the rehabilitation needs of patients, and thus improve the overall use effect.

[0034] The diameter of each of the positioning through holes ranges from 3mm to 10mm, which is used to ensure the stable fixation of the electrode sheet and facilitate the passage of the connecting line. The electrode sheet fixing member is also included, which fixes the electrode sheet to the inner side of the mask body and includes clamps, clips or adhesives. Specifically, the electrode sheet fixing member is responsible for firmly fixing the electrode sheet to the inner side of the mask body. These fixing members can be clamps, which tightly fix the electrode sheet through a clamping mechanism; clips, which are a bracket-type design that effectively supports the electrode sheet and maintains its position stable during use; or adhesives, such as glue or special tape, which provide sustained adhesion to ensure that the electrode sheet does not easily fall off during the entire use.

[0035] In order to enable the device to stimulate facial nerves and muscles, the electrode sheet in the device needs to be connected to the power supply unit, i.e. the electrotherapy instrument, through the connecting line. The electrotherapy instrument mainly includes a power supply, a low-frequency pulse module and a control module. The control module is connected to the power supply, the low-frequency pulse module and the connecting line, respectively, and is responsible for accurately controlling the stimulation of the electrode sheet by the low-frequency pulse module through the adjustment of the control module after starting the power supply, ensuring that the electrode sheet can work under appropriate parameters to achieve the best treatment effect and thus promote the recovery of facial nerves and muscles.

[0036] Therefore, the device can achieve simultaneous stimulation of multiple facial nerve and muscle regions, fully utilizing the multi-channel design to ensure that the electrode sheet can cover key areas such as the frontalis muscle, orbicularis oculi muscle, buccinator muscle and orbicularis oris muscle. The multi-channel stimulation function not only improves the efficiency of use, but also can simultaneously act on multiple target muscle regions in a single use, thereby accelerating the recovery process and enhancing the overall use experience of the wearer. This flexibility and efficiency are a major advantage of the device, making it more widely applicable in clinical applications.
