Description

Technical Field

[0001] The utility model relates to an electrode patch and an electrode device for electrocardiograph leads, belonging to the technical field of electrocardiogram examination. Background Technique

[0002] Electrocardiogram (ECG) is a technology that uses an electrocardiograph to record the electroactivity change graph generated by each cardiac cycle from the body surface. Electrocardiogram examination is one of the most commonly used clinical examinations, and its application range is wide. It can record the normal electroactivity of the human heart, help diagnose arrhythmias, help diagnose myocardial ischemia, myocardial infarction and its location, diagnose heart enlargement and hypertrophy, judge the impact of drugs or electrolyte conditions on the heart, and judge the status of artificial cardiac pacing.

[0003] When examining a patient's electrocardiogram, a suction electrode connected to the electrocardiograph lead wire needs to be adsorbed on the human body, and the electroactivity of the heart is collected through the suction electrode and displayed on the electrocardiograph after transformation. The commonly used suction electrodes in clinical practice mainly consist of a rubber suction ball and a metal suction bowl connected thereto. Squeezing the rubber suction ball generates negative pressure in the metal suction bowl, thereby adsorbing on the human body. However, in our clinical work, we often encounter some patients who are overly emaciated, and their skin is dry and loose, resulting in difficulty for the suction electrode to adhere and being prone to falling off. This will interfere with the formed result image, affect the clinical diagnosis of patients, and increase the burden of clinical work.

[0004] In response to the above problems, there is now also a solution that uses an electrode patch to replace the suction electrode. For example, the patent with the application number CN202122985425.0 discloses a replacement device for an electrocardiograph suction electrode. The replacement device includes an electrode patch, a connector, a fixing clip, a first jack, and a lead wire. One side of the electrode patch is attached to the human skin, and a connector is provided on the other side of the electrode patch. The front end of the fixing clip clamps on the connector, and the rear end of the fixing clip is electrically connected to the electrocardiograph through the lead wire. A first jack is opened on the fixing clip, and the top end of the connector is clamped in the first jack. This patent uses an electrode patch to replace the suction electrode, which can effectively connect the patient's skin and is easy to fix. However, the electrode patch in this replacement device needs to establish a connection relationship with the fixing clip through the connector to complete the transmission of the electrocardiogram signal. Such a clamping connection structure is not as firm as the connection method between the existing suction electrode and the lead wire. Even if a snap connection structure is used, the commonly used suction electrode in our clinic is still used. If a thin patient is encountered, the suction electrode needs to be replaced, which is very inconvenient to operate and will greatly increase the burden of clinical work.

[0005] Therefore, providing a more reasonable electrode device for electrocardiogram acquisition, which can not only conveniently and effectively connect the patient's skin, reduce the interference to the result image caused by poor contact, but also does not increase the burden of clinical work, is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide an electrode patch and an electrode device for electrocardiograph leads, which have an ingenious structure and a reasonable design. The electrode patch can effectively connect to the patient's skin and reduce poor contact. When the electrode patch is used, there is no need to replace the most commonly used suction ball electrode. The operation is convenient and the clinical workload will not be increased.

[0007] The first object of the utility model is achieved through the following technical solutions:

[0008] An electrode patch for electrocardiograph leads comprises a patch body, characterized in that: a mounting platform is provided at the top center of the patch body, a concave cavity is opened at the center of the mounting platform, a soft elastic body is installed in the concave cavity, a flexible conductive film is provided on the upper surface of the soft elastic body, and the flexible conductive film is connected to the conductive glue in the patch body through a wire; a suction cup clamping mechanism is also provided in the soft elastic body, and the suction cup clamping mechanism can hold the metal suction cup in a linked manner when the metal suction cup absorbs the soft elastic body.

[0009] As a further improvement of the present invention, the suction cup clamping mechanism includes two arc-shaped holding blocks symmetrically arranged at 180 degrees, the lower part of the arc-shaped holding block is buried in the soft elastic body, and the inner circumference of the lower part of the arc-shaped holding block is provided with a step extending inward, the height of the step gradually increases from the outside to the inside, the outer diameter of the highest point of the step is smaller than the inner diameter of the metal suction cup, and the outer diameter of the lowest point of the step is larger than the inner diameter of the metal suction cup.

[0010] As a further improvement of the utility model, the inner surface shape of the upper part of the arc-shaped holding block matches the outer surface shape of the lower part of the metal suction cup, and is an arc-shaped curved surface with a radius gradually increasing from top to bottom.

[0011] As a further improvement of the utility model, a conductive sheet is provided on the inner surface of the arc-shaped holding block, and the conductive sheet is also connected to the conductive glue in the patch body through a wire.

[0012] As a further improvement of the present invention, the upper surface of the soft elastic body is configured to be a convex arc shape.

[0013] As a further improvement of the present invention, the outer diameter of the flexible conductive film is smaller than the inner diameter of the metal suction cup.

[0014] As a further improvement of the present invention, the soft elastic body is made of silicone or rubber material.

[0015] As a further improvement of the utility model, the flexible conductive film is an ITO film.

[0016] The second purpose of the utility model is achieved through the following technical solutions:

[0017] The electrode device for electrocardiograph leads, including a suction ball electrode, is characterized in that: it further includes the above-mentioned electrode patch.

[0018] Compared with the prior art, the utility model has the following advantages:

[0019] 1). The utility model improves the existing electrode patch. By adding an installation platform at the top of the electrode patch, opening a concave cavity in the center of the installation platform, and installing a soft elastic body in the concave cavity, the improved electrode patch can be directly adsorbed and matched with the commonly used suction ball electrode. The flexible conductive film on the upper surface of the soft elastic body can ensure the reliable transmission of electrocardiogram signals. After adopting such an electrode patch, it is not necessary to replace the rubber suction ball during operation, which can greatly improve work efficiency.

[0020] 2). The utility model also ingeniously designs a suction bowl clamping mechanism that can clamp the metal suction bowl, so as to ensure that the metal suction bowl and the electrode patch can be reliably and tightly connected together. And the suction bowl clamping mechanism is linked with the operation of adsorbing the soft elastic body of the metal suction bowl, that is, the adsorption and clamping are completed synchronously, and the operation is very convenient.

Detailed Embodiment

[0027] The following further describes the utility model with reference to specific drawings and embodiments.

[0028] Embodiment 1

[0029] As Figures 1 to 4As shown, embodiment 1 discloses an electrode patch for electrocardiograph leads, comprising a patch body 1, a mounting platform 1.1 is provided at the top center of the patch body 1, a concave cavity for a metal suction cup 7 to sink into is provided at the center of the mounting platform, a soft elastic body 2 which can be adsorbed by the negative pressure of the metal suction cup 7 is installed in the concave cavity, a flexible conductive film 3 is provided on the upper surface of the soft elastic body 2, and the flexible conductive film 3 is connected to the conductive glue 1.2 in the patch body 1 through a wire.

[0030] When using it specifically, first wipe the skin where the electrode patch is placed with an alcohol cotton pad, then peel off the release paper on the electrode patch, and stick the electrode patch on the corresponding position on the patient's skin [conductive liquid can be applied as appropriate during operation to make the skin better contact with the conductive glue 1.2 in the electrode patch]. Then put the metal suction cup 7 in the suction ball electrode into the concave cavity [the rubber suction ball 6 is pre-flattened] and pressed against the upper surface of the soft elastic body 2, and then release the rubber suction ball 6, so that the metal suction cup 7 is adsorbed on the soft elastic body 2 by negative pressure, and because the upper surface of the soft elastic body 2 is provided with a flexible conductive film 3, when the soft elastic body 2 is deformed by negative pressure adsorption, the flexible conductive film 3 will contact with the inner surface of the rubber suction ball 6 to establish an electrical connection relationship, thereby completing the transmission of the ECG signal [conductive liquid can also be applied as appropriate during operation to ensure the conductive performance]. By adopting such an electrode patch, we do not need to replace the rubber suction ball 6 during operation, which can greatly improve the work efficiency of medical staff.

[0031] In order to ensure that the metal suction cup 7 and the electrode patch can be reliably and tightly connected together, a suction cup clamping mechanism is also provided in the soft elastic body 2, and the suction cup clamping mechanism can hold the metal suction cup 7 in a linked manner when the metal suction cup 7 absorbs the soft elastic body 2.

[0032] The suction cup clamping mechanism in the present embodiment 1 mainly includes two arc-shaped clamping blocks 4 arranged symmetrically at 180 degrees, the lower part of the arc-shaped clamping blocks 4 is buried in the soft elastic body 2, and the inner peripheral side of the lower part of the arc-shaped clamping blocks 4 is provided with a step 4a extending inward, the height of the step 4a gradually increases from the outside to the inside, the outer diameter of the highest part of the step 4a is smaller than the inner diameter of the metal suction cup 7, and the outer diameter of the lowest part of the step 4a is larger than the inner diameter of the metal suction cup 7. With such arrangement, when the metal suction cup 7 is placed in the concave cavity and pressed downward, the metal suction cup 7 will indirectly contact the step 4a, and the downward pressure of the metal suction cup 7 will drive the step 4a to move inward, so that the two symmetrically arranged arc-shaped clamping blocks 4 move toward each other and hold the metal suction cup 7, and the approach of the arc-shaped clamping blocks 4 and the downward pressure and negative pressure adsorption of the metal suction cup 7 are synchronously linked, and the operation is very convenient.

[0033] like Figure 3 , Figure 4As shown, in Embodiment 1, the inner surface shape of the upper part of the arc-shaped holding block 4 matches the outer surface shape of the lower part of the metal suction cup 7, which is an arc-shaped curved surface with a radius gradually increasing from top to bottom. This can greatly improve the holding stability and firmness of the arc-shaped holding block 4 on the metal suction cup 7.

[0034] As Figure 3 , Figure 4 shown, in Embodiment 1, the inner surface of the arc-shaped holding block 4 is preferably provided with a conductive sheet 5, and the conductive sheet 5 is also connected and conducted through a wire to the conductive adhesive 1.2 in the patch body 1, which is beneficial to ensuring the connection and conduction between the metal suction cup 7 and the conductive adhesive 1.2 in the patch body 1.

[0035] As Figure 3 , Figure 4 shown, in Embodiment 1, the upper surface of the soft elastomer 2 is set as a convex arc shape, so that when the metal suction cup 7 presses down, the soft elastomer 2 can more smoothly enter into the metal suction cup 7, improving the adsorption stability.

[0036] As Figure 2 , Figure 3 shown, in Embodiment 1, the outer diameter of the flexible conductive film 3 is smaller than the inner diameter of the metal suction cup 7, which can ensure that the edge of the metal suction cup 7 is in contact with the soft elastomer 2, and the airtight performance after negative pressure adsorption is good.

[0037] The soft elastomer 2, the flexible conductive film 3 and the conductive sheet 5 in the present utility model can all be made of conventional materials in the prior art, such as silicone or rubber materials. For example, the soft elastomer 2 can be made of silicone or rubber materials, the flexible conductive film 3 can be made of ITO film, and the conductive sheet 5 can be made of copper sheet.

[0038] Embodiment 2

[0039] As Figure 5 shown, Embodiment 2 discloses an electrode device for an electrocardiograph lead, including a suction ball electrode and the electrode patch in Embodiment 1. The suction ball electrode is an existing product, including a rubber suction ball 6, a metal suction cup 7 connected to the rubber suction ball 6, and a lead wire 8 connecting the metal suction cup 7. When in use, the electrode patch is attached to the patient's chest to collect the patient's electrocardiogram signal, and the collected electrocardiogram signal is transmitted to the electrocardiograph through the metal suction cup 7 and the lead wire 8, so that the patient's physiological and pathological conditions can be visually observed.

[0040] The above description only shows the preferred embodiments of the present utility model, and the above specific embodiments do not limit the present utility model. Within the scope of the technical idea of the present utility model, various deformations and modifications can occur. Any retouching, modification or equivalent replacement made by those of ordinary skill in the art according to the above description belongs to the scope protected by the present utility model.
