Description

Technical Field

[0001] This utility model relates to the field of electrocardiogram diagnostic equipment technology, specifically to an extendable, non-detachable electrode sheet. Background Technology

[0002] An electrocardiogram (ECG) is a technique that uses an electrocardiograph to record the changes in electrical activity of the heart during each cardiac cycle from the body surface. It is a simple, convenient, low-cost, and non-invasive method for detecting and diagnosing cardiac electrophysiology and heart diseases. It is also a primary basis for the treatment of cardiovascular diseases, offering advantages such as reliable diagnosis, convenient method, and no damage to the patient. Currently, it is one of the most commonly used clinical examinations, with wide applications and a crucial role.

[0003] During an electrocardiogram (ECG) examination, electrodes for chest and limb leads need to be attached to the patient. For secure fixation of the chest electrodes, a suction cup-like mechanism is typically used, often employing a bulb-like suction device. However, because the chest leads are placed in the rib area, the suction bulb may not adhere well to the skin, leading to it falling off, affecting the ECG examination and interfering with the results, especially in patients with uneven skin texture (such as those who are thin, have scarred skin), or those with dry, flaky skin. Currently, both chest and limb leads use metal patches that directly contact the skin, posing a risk of electric shock in case of operational errors or extreme situations. Furthermore, commonly used chest and limb leads are often reused, which, in the complex hospital environment and among diverse patients, could lead to contact infections, failing to meet infection control requirements. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology mentioned above, and to provide an extendable anti-detachment electrode sheet. It adopts a gel structure with good extensibility and stability to achieve adhesion to the human body, reducing the probability of electrode detachment and displacement. Moreover, it can be used as an integrated chest lead or separately, which has better flexibility in use.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: A stretchable, non-detachable electrode pad includes a chest lead electrode, a limb lead electrode, and a cable. The chest lead electrode includes multiple first electrode pads, each first electrode pad comprising an absorbent patch and a metal sheet, with the metal sheet encapsulated within the absorbent patch. The absorbent patch is made of a stretchable gel material and includes a contact surface and a back surface. The absorbent patch is configured with conductive gel at least in the corresponding metal sheet area of ​​the contact surface. The absorbent patches of the multiple first electrode pads are sequentially connected, and adjacent absorbent patches have an easy-tear structure at the connection point. The limb lead electrode includes multiple second electrode pads. The cable includes a main conductor and multiple sub-conductors, with the sub-conductors connected in parallel to the main conductor via branch connectors. Each first electrode pad and second electrode pad is connected to a sub-conductor.

[0006] Preferably, the second electrode sheet also includes an adsorption patch and a metal sheet, with the metal sheet encapsulated in the adsorption patch. The adsorption patch is made of a stretchable gel material and includes a contact surface and a back surface. The adsorption patch is set as a conductive gel at least in the corresponding metal sheet area of ​​the contact surface. The adsorption patches of the multiple second electrode sheets are set relatively independently.

[0007] Preferably, the number of the first electrode sheets is six, wherein the adsorption patches of two of the first electrode sheets are set as corner patches, and the adsorption patches of the remaining four first electrode sheets are set as rectangular patches. Each corner patch is connected to rectangular patches on both sides, and the folding directions of the two corner patches are opposite.

[0008] Preferably, the back of the absorbent patch is provided with an elastic silicone protrusion that can be pressed with a finger, and the elastic silicone protrusion faces the metal sheet.

[0009] Preferably, the tear-off structure is a tear line with a dotted pattern.

[0010] Preferably, the multiple first electrode sheets are each provided with a color identification mark of a different color, and each color-corresponding first electrode sheet is also provided with a word identification mark; the multiple second electrode sheets are each provided with a color identification mark of a different color.

[0011] Preferably, the main line is equipped with a conversion connector, which includes a detachable docking end a and a docking end b. The docking end a is connected to the main line, and the docking end b is connected to a universal electrocardiograph interface.

[0012] Preferably, the cable is provided with a cable bundle mechanism for organizing and storing sub-conductors and main conductors.

[0013] Compared with existing technologies, the stretchable anti-detachment electrode sheet using the above technical solution has the following beneficial effects: Both the chest and limb leads use a gel material with excellent extensibility and adsorption stability to coat the metal sheet. This effectively prevents electrode dislodgement and displacement in patients with varying body types, such as those who are thin or have excessive skin, while also reducing ECG data noise. The contact surface of the electrode pads uses conductive gel, ensuring conductivity while providing better fit and adsorption stability. The elastic silicone protrusions on the back of the adsorption patch can be pressed with a finger to increase adsorption force and improve electrode placement stability.

[0014] The chest lead electrode adopts a detachable integrated structure. Adjacent adsorption patches are connected by easy-tear lines for easy separation. This design allows for flexible use depending on actual needs, such as different patient body types or different examination sites. The electrodes can be placed directly as a whole or torn apart for individual use, providing greater flexibility in application scenarios.

[0015] The lead wire can be disconnected from the universal ECG machine interface via an adapter, making the electrode pads and their connected lead wires a detachable unit that can be designed for single use. This avoids contact infection in complex hospital environments and for different patients, and better meets hospital infection control requirements. Furthermore, the detachable and replaceable overall structure allows for the selection of different lead electrode models for patients of different body types. Attached Figure Description

Detailed Implementation

[0021] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0022] like Figures 1 to 4 The extendable, non-detachable electrode pads shown include chest lead electrodes, limb lead electrodes, and cables.

[0023] The chest lead electrodes include six first electrode pads, each comprising an absorbent patch and a metal plate, with the metal plate encapsulated within the absorbent patch. The absorbent patch is made of a highly malleable gel material and includes a contact surface and a back surface. Conductive gel is used in the corresponding metal plate area on the contact surface of the absorbent patch. The conductive gel contacts the metal plate to ensure normal transmission of electrical signals. Due to the superior malleability and absorbent stability of the gel material, electrode detachment and displacement can be effectively prevented in patients with different conditions such as emaciation or excessive skin flaking, while also reducing noise in the ECG data.

[0024] The six first electrode pads are sequentially connected with adhesive patches. Adjacent adhesive patches have a tear-away structure at the connection point, indicated by a dotted tear line, allowing for manual separation of the individual first electrode pads. Two of the six first electrode pads have corner-shaped adhesive patches, while the remaining four have rectangular adhesive patches. Each corner patch is connected to two rectangular patches on either side, with the corner angles of the two corner patches facing opposite directions. The easy-tear lines allow for flexible placement, depending on the specific examination needs (e.g., based on patient size or examination site), either as a single unit placed directly on the examination site or individually separated for each electrode pad.

[0025] The back of the first electrode pad has a springy silicone protrusion that can be pressed with a finger, with the springy silicone protrusion facing the metal sheet. Pressing the springy silicone protrusion with a finger increases the adhesion and improves the stability of the first electrode pad.

[0026] The first electrode sheet is equipped with color identification marks, with the six first electrode sheets corresponding to the color identification marks being red, yellow, green, brown, black, and purple, respectively. The first electrode sheets are also equipped with letter identification marks, with the first electrode sheets corresponding to red, yellow, green, brown, black, and purple being marked with the letters V1, V2, V3, V4, V5, and V6, respectively.

[0027] The limb lead electrode includes four second electrode pads. Each second electrode pad has the same individual structure as the first electrode pad; that is, it also includes an absorbent patch and a metal sheet, with the metal sheet encapsulated within the absorbent patch. The absorbent patch is made of a stretchable gel material and includes a contact surface and a back surface. The area corresponding to the metal sheet on the contact surface of the absorbent patch is set with conductive gel. The four absorbent patches of the second electrode pad are relatively independently configured. The second electrode pads also have color-coded identification marks, with the four second electrode pads corresponding to red, yellow, green, and black color-coded marks, respectively.

[0028] The cable consists of a main conductor and multiple sub-conductors. The sub-conductors are connected in parallel to the main conductor via branch connectors. Six first electrode plates are each connected to one sub-conductor, and four second electrode plates are each connected to one sub-conductor. The main conductor is equipped with an adapter, which includes two detachable terminals, A and B. Terminal A connects to the main conductor, and terminal B connects to a universal ECG machine interface compatible with most ECG machines on the market. The cable features a cable management mechanism for organizing and storing the sub-conductors and the main conductor. This mechanism uses Velcro cable ties, which are located on the main conductor. During organization and storage, multiple sub-conductors can be bundled and secured on the main conductor.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
