Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a flexible and fixed physiotherapy electrode pad. Background Technology

[0002] Traditional physiotherapy electrode pads, as important tools in fields such as physical therapy and rehabilitation, directly affect treatment outcomes and patient experience. However, in practical applications, these electrode pads face numerous challenges.

[0003] First, inconvenient fixation is a common problem. Traditional electrode pads are often fixed using adhesive or strapping methods, but these methods are often difficult to adapt to the curves and shapes of different body parts, causing the electrode pads to easily fall off or shift, thus affecting the treatment effect. In addition, some patients may experience discomfort such as skin redness, swelling, and itching due to skin sensitivity or prolonged use of adhesive electrode pads.

[0004] Secondly, unstable conductivity is a major drawback of traditional electrode pads. Because the contact area between the electrode pad and the skin is limited and easily affected by secretions such as sweat and oil, conductivity decreases, thus affecting the transmission of electrical stimulation signals. This not only reduces the therapeutic effect but may also cause unnecessary pain to the patient.

[0005] Furthermore, skin discomfort is another area where traditional electrode pads need improvement. Some electrode pads, due to improper materials or design, can easily cause friction or pressure on the skin, leading to discomfort such as pain and itching. This discomfort not only affects the treatment outcome but may also reduce patient adherence.

[0006] While some improved therapeutic electrode pads have emerged on the market in an attempt to address these issues, their flexibility, comfort, and fixation still require improvement. For example, some electrode pads, despite employing softer materials or more advanced fixation methods, still have limitations in adapting to different body parts and shapes. Furthermore, some electrode pads, while improving conductivity, may sacrifice comfort or fixation effectiveness.

[0007] Therefore, developing a physiotherapy electrode pad that can be flexibly fixed while ensuring good conductivity and comfort is particularly important. Such an electrode pad needs to comprehensively consider multiple aspects such as the patient's physical characteristics, treatment needs, and user experience, achieving a perfect combination of fixation, conductivity, and comfort through innovative design and material selection. Utility Model Content

[0008] This utility model aims to at least partially solve one of the technical problems in the related art.

[0009] Therefore, the purpose of this utility model is to propose a flexible and fixed physiotherapy electrode pad with good conductivity and comfort, which can ensure the effectiveness of electrical stimulation therapy and the user experience of patients. The design of the flexible fixing device allows the electrode pad to adapt to the curves of different body parts, thereby improving the treatment effect. The application of a micro pressure sensor allows the electrode pad to monitor the contact pressure with the skin in real time, providing a basis for adjusting treatment parameters. The anti-allergy protective layer effectively prevents patients from having allergic reactions during use.

[0010] To achieve the above objectives, this utility model proposes a flexible and fixed physiotherapy electrode pad, comprising an electrode pad, a fixing device, and a conductive layer. The electrode pad surface is covered with a micro-adhesive coating, and the edge of the electrode pad is provided with a retractable elastic frame. A micro pressure sensor is embedded in the central contact area of ​​the electrode pad, and the pressure sensor can transmit data to a connected device. The fixing device includes fixing components, which are respectively disposed at both ends of the electrode pad, and the fixing components are elastic and movably connected at both ends. The conductive layer is located on the side of the electrode pad that contacts the skin.

[0011] This invention relates to a flexible and fixed physiotherapy electrode pad, which has good conductivity and comfort, ensuring the effectiveness of electrical stimulation therapy and the patient's user experience. The flexible fixing device design allows the electrode pad to adapt to the curves of different body parts, improving the treatment effect. The application of a micro pressure sensor allows the electrode pad to monitor the contact pressure with the skin in real time, providing a basis for adjusting treatment parameters. The anti-allergy protective layer effectively prevents patients from having allergic reactions during use.

[0012] In addition, the flexible and fixed physiotherapy electrode pad proposed in the above application may also have the following additional technical features:

[0013] Specifically, the fixing component includes four fixing straps, two sets of fixing openings, and two sets of fixing buckles. The four fixing straps are arranged in pairs at both ends of the electrode sheet. The two sets of fixing openings are equidistantly arranged on two of the four fixing straps. The two sets of fixing buckles are equidistantly arranged on the other two of the four fixing straps, and the two sets of fixing buckles are movably connected to the two sets of fixing openings.

[0014] Specifically, the micro-adhesive coating is a medical-grade silicone coating.

[0015] Specifically, the elastic frame is made of elastic silicone material, which has good flexibility and resilience.

[0016] Specifically, the conductive layer further includes an anti-allergy protective layer, which is made of medical-grade non-woven fabric.

[0017] Specifically, the miniature pressure sensor is a thin-film pressure sensor.

[0018] The advantages of this invention compared to existing technologies are as follows:

[0019] (1) The physiotherapy electrode has good conductivity, which can ensure the effective transmission of electrical stimulation treatment signals, thereby improving the treatment effect and ensuring that the patient obtains the expected physiotherapy effect.

[0020] (2) The electrode pads are equipped with flexible fixing devices that can closely fit the curves of different body parts, preventing the electrode pads from falling off or shifting during use, thereby improving the stability and accuracy of treatment.

[0021] (3) The application of miniature pressure sensors enables the electrode pads to monitor the contact pressure with the skin in real time, providing a basis for adjusting treatment parameters.

[0022] (4) The electrode pads are specially designed with an anti-allergy protective layer, made of safe materials such as medical-grade non-woven fabric, which effectively prevents patients from having allergic reactions during use and ensures the safety of patients.

[0030] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0031] The following description, in conjunction with the accompanying drawings, describes a flexible and fixed physiotherapy electrode pad according to an embodiment of the present invention.

[0032] like Figures 1-4 As shown in the figure, a flexible and fixed physiotherapy electrode pad according to an embodiment of the present invention includes an electrode pad 1, a fixing device 2, and a conductive layer 3. The surface of the electrode pad 1 is covered with a micro-adhesive coating 11, and the edge of the electrode pad 1 is provided with a retractable elastic frame. A micro pressure sensor 4 is embedded in the central contact area of ​​the electrode pad 1. The pressure sensor 4 can transmit data to a connected device. The fixing device 2 includes fixing components 21, which are respectively disposed at both ends of the electrode pad 1. The fixing components 21 are elastic and movably connected at both ends. The conductive layer 3 is located on the side of the electrode pad 1 that contacts the skin.

[0033] It is understandable that electrode 1 is the core part of the entire physiotherapy device, used to directly contact the user's skin to transmit electrotherapy signals.

[0034] The surface of electrode pad 1 is covered with a micro-adhesive coating 11: This micro-adhesive coating can ensure that the electrode pad adheres firmly to the skin, while maintaining a certain degree of breathability to avoid discomfort caused by prolonged use.

[0035] The electrode pad 1 has a retractable elastic frame at its edge: this design allows the electrode pad to be adjusted appropriately according to the user's body contour, thereby providing a more fitting and secure fit.

[0036] A miniature pressure sensor 4 is embedded in the central contact area of ​​electrode pad 1. This sensor can monitor the pressure between the electrode pad and the skin in real time, ensuring safety and comfort during the treatment process. Pressure sensor 4 can also transmit data to a connected device for monitoring and adjustment by medical staff or users.

[0037] The fixing device 2 is used to further secure the electrode pad 1 to the skin and prevent it from falling off or shifting during use.

[0038] The fixing device 2 includes fixing components 21: these fixing components are respectively disposed at both ends of the electrode pad 1, are elastic and movably connected at both ends, so that they can be flexibly adjusted according to the size of the user's body parts, ensuring the stable fixing of the electrode pad on different body parts.

[0039] The conductive layer 3 is located on the side of the electrode 1 that contacts the skin and is the key part of the electrode 1 that enables it to transmit electrotherapy signals.

[0040] The conductive layer 3 is made of silver fiber material, which has good conductivity and biocompatibility, ensuring the effective transmission of electrotherapy signals while reducing skin irritation.

[0041] In one embodiment of this utility model, such as Figures 2-3 As shown, the fixing component 21 includes four fixing straps 211, two sets of fixing openings 212, and two sets of fixing buckles 213. The four fixing straps 211 are respectively arranged in pairs at both ends of the electrode sheet 1. The two sets of fixing openings 212 are equidistantly arranged on two of the four fixing straps 211. The two sets of fixing buckles 213 are equidistantly arranged on the other two fixing straps of the four fixing straps 211, and the two sets of fixing buckles 213 are movably connected to the two sets of fixing openings 212 respectively.

[0042] It can be understood that the fixing straps 211 are the main part of the fixing assembly 21, and there are four of them, which are set in pairs at both ends of the electrode sheet 1.

[0043] The two sets of fixing bands 211 are located on the left and right sides of the electrode sheet 1, respectively, forming two independent fixing systems.

[0044] The retaining strap 211 is made of a soft and flexible material to ensure that it does not cause discomfort to the user when securing the electrode pads, while providing sufficient fastening force.

[0045] The fixing port 212 is an opening provided on the fixing band 211, which is used to cooperate with the fixing buckle 213 to fix the electrode sheet.

[0046] The fixing buckle 213 is a part that cooperates with the fixing opening 212 and is used to firmly connect the fixing strap 211 together, thereby fixing the electrode sheet 1.

[0047] The design of the retaining clip 213 allows it to be easily connected to and disconnected from the retaining port 212, making it convenient for users to adjust the position and tightness of the electrode sheet as needed.

[0048] In summary, the fixing component 21, through the cooperation of four fixing straps 211, two sets of fixing ports 212, and two sets of fixing buckles 213, achieves flexible fixation of the electrode pad 1 during use. Users can adjust the tightness of the fixing straps 211 and the connection position of the fixing buckles 213 with the fixing ports 212 according to their body contours and physiotherapy needs to ensure a stable fit and comfortable experience for the electrode pad.

[0049] In one embodiment of this utility model, such as Figure 4 As shown, the micro-adhesive coating 11 is a medical-grade silicone coating, and the elastic frame is made of elastic silicone material, which has good flexibility and resilience.

[0050] It is understandable that the micro-adhesive coating 11 covering the surface of the electrode pad 1 serves two main purposes: first, to increase the adhesion between the electrode pad and the skin, ensuring that the electrode pad will not easily fall off during use; and second, to maintain a certain degree of breathability and comfort, avoiding adverse effects on the skin from prolonged contact. The micro-adhesive properties of the medical-grade silicone coating ensure that the electrode pad can adhere firmly without causing excessive stickiness to the skin, thereby improving the user experience.

[0051] The elastic frame around the edge of electrode pad 1 is designed to enhance its adaptability and stability. On one hand, the elastic frame allows for appropriate adjustment based on the user's body contours, enabling the electrode pad to better conform to skin surfaces of different shapes and sizes. On the other hand, the flexibility and resilience of the elastic frame ensure that the electrode pad maintains a stable shape and fit during prolonged use, thereby improving the therapeutic effect.

[0052] In one embodiment of this utility model, such as Figure 4 As shown, the conductive layer 3 also includes an anti-allergy protective layer 31, which is made of medical-grade non-woven fabric.

[0053] It is understood that the conductive layer 3 is one of the core components of the physiotherapy electrode pad. It is located on the side of the electrode pad 1 that contacts the skin, and its main function is to transmit electrotherapy signals to the deep layers of the skin to achieve the purpose of physiotherapy.

[0054] The primary function of the hypoallergenic protective layer 31 is to prevent the conductive material in the conductive layer 3 from directly contacting the skin, thereby reducing the risk of allergies or irritation. The medical-grade non-woven fabric material has excellent skin adaptability, ensuring comfort and safety for users during prolonged use of the therapeutic electrode pads.

[0055] The hypoallergenic protective layer 31, made of medical-grade nonwoven fabric, not only boasts excellent hypoallergenic properties but also good breathability and moisture absorption, keeping the skin dry and comfortable. Furthermore, the nonwoven fabric material also possesses certain antibacterial properties, helping to reduce the risk of bacterial infection during use.

[0056] In one embodiment of this utility model, such as Figure 3 As shown, the miniature pressure sensor 4 is a thin-film pressure sensor.

[0057] It is understood that the miniature pressure sensor 4 employs thin-film pressure sensing technology, which is a sensor that integrates a pressure-sensitive element in the form of a thin film onto a substrate material. Thin-film pressure sensors typically have advantages such as small size, light weight, high sensitivity, and fast response speed.

[0058] Working principle: When electrode 1 comes into contact with the skin and a certain pressure is applied, the sensitive element of the thin-film pressure sensor 4 deforms, causing changes in physical quantities such as internal resistance, capacitance, or piezoelectric effect. These changes can be converted into electrical signals by the circuit, and then read and recorded by the connected device.

[0059] Advantages: The thin-film pressure sensor 4 not only features high precision and high sensitivity, but also good flexibility and bendability, which can adapt to the curves and shapes of different body parts.

[0060] Application of physiotherapy electrode pads:

[0061] In the therapeutic electrode pads, the thin-film design of the miniature pressure sensor 4 allows it to fit snugly within the central contact area of ​​the electrode pad 1 without adding extra thickness or weight. This enables the electrode pads to maintain their original therapeutic effect while simultaneously monitoring the contact pressure with the skin in real time, providing users with a more personalized therapeutic experience. Medical personnel or users can adjust the position and tightness of the electrode pads based on the pressure data provided by the sensor 4 to ensure safety and comfort during the therapeutic process.

[0062] It should be noted that the control method of this application can be automatically controlled by a controller. The control method of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, this application is mainly used to protect mechanical structures, so the control method and circuit connection will not be explained in detail here.
