Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a body surface electrode for physiotherapy. Background Technology

[0002] With the continuous development of medical technology, physiotherapy plays an increasingly prominent role in disease treatment and rehabilitation. As a key component of physiotherapy equipment, the performance of surface electrodes directly affects the effectiveness of physiotherapy and the patient's experience. Currently, various types of surface electrodes for physiotherapy exist on the market, playing important roles in different physiotherapy scenarios. However, as patients' demands for comfort and safety during physiotherapy continue to rise, existing surface electrodes for physiotherapy still require improvement in certain aspects.

[0003] Existing therapeutic surface electrodes typically consist of a conductive part, an adhesive part, and an encapsulation part. The conductive part generally uses a metal electrode or conductive gel to contact the human skin and conduct current. The adhesive part often uses pressure-sensitive adhesive to fix the electrode to the human body surface through adhesion. The encapsulation part is mainly for protecting the internal structure of the electrode, while also improving the electrode's comfort and hygiene.

[0004] In practical physiotherapy scenarios, existing surface electrodes for physiotherapy have several problems. For example, when removing the electrodes, they often require direct contact with the electrode body, which can lead to electrode displacement and affect the therapeutic effect. In some physiotherapy sessions that require prolonged electrode fixation, direct removal can irritate the skin, especially for patients with sensitive skin, exacerbating their discomfort. Furthermore, existing removal methods are not convenient enough, requiring considerable time and effort to remove the electrodes, thus affecting the efficiency of the physiotherapy. Therefore, this art proposes surface electrodes for physiotherapy to address these issues. Utility Model Content

[0030] Reference Figures 1-4This utility model provides an embodiment of a surface electrode for physiotherapy, comprising an outer frame 1. The outer frame 1 serves as the basic framework of the overall structure and is typically made of a material with certain strength and toughness, such as plastic. Its shape can be designed as circular, square, or other specific shapes according to actual needs to adapt to different body parts and treatment requirements. The outer frame 1 not only provides stable support for other structural components but also protects the internal components, preventing adverse effects of the external environment on the electrode's performance. A conductive component is included, designed for direct contact with human skin. The conductive component includes an electrode block 2 and a conductive gel 4. The electrode block 2 is located inside the outer frame 1 and is typically made of a material with good conductivity, such as metal or conductive polymer. A wire 3 is fixedly connected to the top of the electrode block 2, connecting it to an external instrument to transmit the current or signal required for treatment. The conductive gel 4 is sleeved on the outside of the electrode block 2 and is electrically connected to it. The conductive gel 4 is typically made of a material with good conductivity and biocompatibility, such as a hydrogel containing electrolytes. When electrode block 2 comes into contact with human skin, conductive gel 4 fills the tiny gaps between electrode block 2 and skin, increasing the contact area and reducing contact resistance, thereby improving current transmission efficiency. An adhesion component assists in the overall structure's fit to human skin. The adhesion component includes pressure-sensitive adhesive 5, the outer side of which is fixedly connected to the inner side of the outer frame 1. Pressure-sensitive adhesive 5 is typically made of materials with good adhesion and biocompatibility, such as acrylic pressure-sensitive adhesive 5 or silicone pressure-sensitive adhesive 5. When the bottom of electrode block 2 is aligned with the appropriate position on the patient's body and pressed firmly, pressure-sensitive adhesive 5 adheres to the patient's skin, using its adhesiveness to ensure the overall structure remains firmly attached to the patient's surface. The adhesiveness of pressure-sensitive adhesive 5 should be moderate, ensuring the electrode does not easily detach during use while avoiding excessive pulling and damage to the skin when removing the electrode. An encapsulation component encapsulates the overall structure. The encapsulation component includes a buffer layer 6 and a top layer 7. Both the buffer layer 6 and the top layer 7 are fixedly connected to the inner side of the outer frame 1, with the top layer 7 located on top of the buffer layer 6. The buffer layer 6 is made of sponge, which has good elasticity and water absorption, providing cushioning and improving user comfort. Simultaneously, the buffer layer 6 absorbs sweat from the skin surface, keeping the skin dry and preventing sweat buildup from affecting the conductivity of the electrode block 2 and the wire 3, as well as the adhesion of the pressure-sensitive adhesive 5. The top layer 7 is made of non-woven fabric, which is soft and breathable, further improving the comfort and breathability of the electrodes. The non-woven fabric also provides some isolation, preventing external impurities from entering the electrode and affecting its performance. A removal assembly is used to remove the entire structure from the human body surface. The removal assembly includes two side flaps 8, one end of which is fixedly connected to the outer sides of the outer frame 1. The side flaps 8 are typically made of the same or similar material as the outer frame 1, possessing a certain degree of strength and toughness.The side wing 8 has holes 9 inside. When the entire structure needs to be removed, the two side wing 8 can be pinched and lifted, or the side wing 8 can be lifted by hooking the holes 9. This allows for removal without direct contact with the entire structure, making it safer and more convenient. It avoids electrode displacement, contamination, or unnecessary skin irritation caused by direct contact with the electrodes.

[0031] Specifically, firstly, one end of the lead wire 3 is connected to the external instrument to ensure that the therapeutic current or signal generated by the external instrument can be stably transmitted to the electrode block 2. Once the connection is complete, various treatment parameters of the external instrument can be transmitted to the electrode through the lead wire 3, providing a basis for the subsequent physiotherapy process. Then, the bottom of the electrode block 2 is aligned with the appropriate position on the patient's body and pressed firmly. During this process, the electrode block 2 needs to be accurately placed on the area to be treated to ensure the targeted treatment effect. When the electrode block 2 is pressed firmly, the pressure-sensitive adhesive 5 will adhere to the patient's skin. The pressure-sensitive adhesive 5 has good adhesion and can quickly form a tight contact with the skin, making the overall structure adhere firmly to the patient's body surface. This firm adhesion ensures that the electrode will not easily shift during the physiotherapy process, ensuring the continuity and stability of the treatment. The buffer layer 6 and the top layer 7 can absorb sweat on the skin surface, keep the skin dry, and prevent sweat accumulation from affecting the conductivity of the electrode block 2 and the lead wire 3 and the adhesion effect of the pressure-sensitive adhesive 5. The buffer layer 6 is made of sponge, which has good elasticity and water absorption. It can absorb sweat produced on the skin surface, preventing sweat from accumulating between the electrode and the skin. Excessive sweat accumulation will reduce the conductivity of the electrode block 2 and the wire 3, affecting the transmission of the treatment current; it will also affect the adhesion of the pressure-sensitive adhesive 5, making the electrode prone to detachment. The top layer 7 is made of non-woven fabric, which is soft and breathable. This further enhances the breathability of the electrode, allowing the skin to breathe, reducing stuffiness, and improving patient comfort. Furthermore, when removing the entire structure, the two side wings 8 can be pinched and lifted, or the side wings 8 can be lifted by hooking the holes 9. This method of removal has significant advantages. First, it avoids direct contact with the entire structure, preventing unnecessary contamination of the electrode. Second, this method is safer. Direct contact with the electrode can cause displacement, especially when the electrode is tightly attached to the skin; forceful pulling can damage the skin. Removing it through the side wings 8 allows for even application of force, reducing skin irritation. Furthermore, using a hook to lift the side wing 8 by hooking it through the hole 9 is very practical in some special situations. This allows for lifting without direct contact with the overall structure, making it safer and more convenient.

[0032] Working principle: First, connect one end of the lead wire 3 to the external instrument. Then, align the bottom of the electrode block 2 with the appropriate position on the patient's body and press it firmly. The pressure-sensitive adhesive 5 will adhere to the patient's skin, making the overall structure adhere to the patient's body surface and remain stable. The buffer layer 6 and the top layer 7 can absorb sweat on the skin surface, keep the skin dry, and prevent sweat accumulation from affecting the conductivity of the electrode block 2 and the lead wire 3 and the adhesion effect of the pressure-sensitive adhesive 5. In addition, when it is necessary to remove the entire structure, you can pinch the two side wings 8 and lift them up, or use the hook to hook the hole 9 and lift the side wings 8. This way, you can pick it up without directly contacting the entire structure, which is safer and more convenient.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
