Description

Technical Field

[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] Medical detection electrodes are widely used in the medical field. Specifically, medical devices can acquire electrical signals from the human body through medical detection electrodes that come into contact with the body, thereby monitoring and diagnosing various biological information. Common medical detection electrodes can include electrocardiogram (ECG) electrodes, which are used to monitor cardiac function by measuring the electrical activity of the heart.

[0004] Patients with leukemia and other cancers require rigorous treatment regimens (including chemotherapy) to manage and eliminate cancer cells. Because some chemotherapy drugs have cardiotoxic effects, patients undergoing chemotherapy need to have electrocardiograms (ECGs) to monitor their heart health. However, patients undergoing chemotherapy have a significantly higher risk of infection than other patients due to their severely compromised immune systems. During routine ECG testing, the ECG electrodes that come into contact with the patient may inadvertently introduce bacteria or other pathogens, causing infection and impacting the patient's overall treatment outcomes and quality of life.

[0005] Therefore, existing medical testing electrodes need to be improved. Utility Model Content

[0026] The following description is exemplary in nature and is not intended to limit the invention, its application, or its uses. It should be understood that in all these figures, similar reference numerals indicate the same or similar parts and features. The figures only schematically illustrate the concept and principles of embodiments of the invention and do not necessarily show the specific dimensions and scale of each embodiment. Certain parts of specific figures may be depicted in an exaggerated manner to illustrate relevant details or structures of embodiments of the invention.

[0027] In the description of the embodiments of this utility model, the directional terms related to "upper" and "lower" are used to describe the upper and lower positions of the views shown in the accompanying drawings. In practical applications, the positional relationship of "upper" and "lower" used herein can be defined according to the actual situation, and these relationships can be reversed.

[0028] In the following description, an electrocardiogram (ECG) electrode will be used as an example to illustrate the medical detection electrode of this invention. Of course, those skilled in the art will understand that this invention is not limited to ECG electrodes, but may include medical detection electrodes for monitoring patient biometrics other than cardiac information.

[0029] Reference Figure 1 The electrocardiogram electrode 1 may include a conductive member 10, a backing 20, an antibacterial pressure-sensitive adhesive 30, a conductive adhesive 40, and a release layer 50. The backing 20 may be formed as a layered backing and has a first side (i.e., Figure 1 The lower side) and the second side opposite to the first side (i.e., Figure 1(The upper side of the backing). The antibacterial pressure-sensitive adhesive 30 and the conductive adhesive 40 can be formed as layered pressure-sensitive adhesive and layered conductive adhesive, respectively. The antibacterial pressure-sensitive adhesive 30 and the conductive adhesive 40 can be disposed on the first side of the backing 20 (i.e., the upper side of the backing). Figure 1 The conductive member 10 can be mounted from the second side of the backing 20 (i.e., the lower side of the backing 20). Figure 1 The upper side of the electrode 1 extends and is electrically connected to the conductive adhesive 40. In the various views and related descriptions of this application, the side of each layer of the electrocardiogram electrode 1 that faces the patient's skin during use is shown and described as the "lower side", and the side of each layer of the medical detection electrode 1 that faces the external environment during use, opposite to the lower side, is referred to as the "upper side".

[0030] Reference Figure 2 The conductive member 10 can extend through the first hole 22 of the backing 20, the second hole 32 of the antibacterial pressure-sensitive adhesive 30, and the third hole 42 of the conductive adhesive 40. The first hole 22, the second hole 32, and the third hole 42 can be located at the center of the backing 20, the antibacterial pressure-sensitive adhesive 30, and the conductive adhesive 40, respectively, so that the conductive member 10 can be positioned at the center of the electrocardiogram electrode 1. The conductive member 10 can include a head 11, a connecting portion 12, and an end plate portion 14. The head 11 can be exposed to the upper side of the backing 20 and can be connected to an electrocardiogram monitoring device (not shown). The connecting portion 12 can extend through the first hole 22, the second hole 32, and the third hole 42. The end plate portion 14 can abut against the conductive adhesive 40 on the lower side to establish an electrical connection with the conductive adhesive 40. The conductive member 10 can be made of metal or other conductors for transmitting electrical signals.

[0031] The backing 20 can be made of non-woven fabric, foam, or any other suitable backing material.

[0032] Antibacterial pressure-sensitive adhesive 30 can be made of pressure-sensitive adhesive with antibacterial properties. For example, Tegaderm from 3M can be used. TM Antibacterial transparent dressing 9124. The electrocardiogram electrode 1 can be firmly bonded to the patient's skin by antibacterial pressure-sensitive adhesive 30, thereby enabling the electrocardiogram electrode 1 to effectively and reliably contact the patient's skin to provide the patient's electrocardiogram signal.

[0033] The conductive adhesive 40 may contain water, polymers, hydrophilic small molecules, and chloride anions, wherein the concentration of chloride anions determines the conductivity of the electrocardiogram electrode 1. (Refer to...) Figure 1 and Figure 3The conductive adhesive 40 can be formed into a generally S-shaped form and can have a hollow portion 43. Specifically, the conductive adhesive 40 may include a first arcuate portion 44, a second arcuate portion 48, and a connecting portion 46 connecting the first arcuate portion and the second arcuate portion. The hollow portion 43 can be a gap region without conductive adhesive. The hollow portion 43 may include a first hollow portion located between the first arcuate portion 44 and the connecting portion 46, and a second hollow portion located between the second arcuate portion 48 and the connecting portion 46.

[0034] Reference Figure 3 When using the ECG electrode 1, the release layer 50 is first removed from the ECG electrode 1, and then the exposed antibacterial pressure-sensitive adhesive 30 and conductive adhesive 40 are pressed downwards to adhere tightly to the patient's skin. The antibacterial pressure-sensitive adhesive 30 is disposed on the upper side of the conductive adhesive 40 and extends beyond the outer periphery of the conductive adhesive 40. Because the conductive adhesive 40 has a hollow portion 43, when the ECG electrode 1 is pressed downwards to adhere to the patient's skin, the upper antibacterial pressure-sensitive adhesive 30 fills the hollow portion 43 of the conductive adhesive 40. Therefore, the antibacterial pressure-sensitive adhesive 30 not only contacts the patient's skin at the outer periphery of the conductive adhesive 40, but also contacts the patient's skin inside the conductive adhesive 40 by filling the hollow portion 43 within the conductive adhesive 40. This results in antibacterial pressure-sensitive adhesive being distributed throughout the center and periphery of the entire ECG electrode 1, thereby preventing the patient from being infected by bacteria and other pathogens due to contact with the ECG electrode 1 through sufficient antibacterial pressure-sensitive adhesive 30. Meanwhile, the hollow portion 43 of the conductive adhesive 40 ensures that the conductive adhesive 40 extends outward to a sufficient area so that the electrocardiogram electrode 1 can obtain sufficient electrical detection signals through the conductive adhesive 40. In the electrocardiogram electrode 1 according to the present invention, the ratio of the area of ​​the antibacterial pressure-sensitive adhesive 30 in contact with the patient's skin to the total area of ​​the electrocardiogram electrode 1 in contact with the patient's skin can be in the range of 60% to 90%, preferably in the range of 67% to 80%.

[0035] Preferably, such as Figure 1 As shown, the first hollow portion and the second hollow portion can be formed symmetrically. In this way, the antibacterial pressure-sensitive adhesive 30 can be symmetrically filled in the first hollow portion and the second hollow portion inside the conductive adhesive 40, so that the electrocardiogram electrode 1 can effectively provide an antibacterial effect in each central area. Preferably, the first arc portion 44 and the second arc portion 48 can also be formed symmetrically with each other, so that the conductive adhesive symmetrically distributed around the center of the electrocardiogram electrode 1 can uniformly and effectively obtain an electrical detection signal.

[0036] Release layer 50 can adhere to antibacterial pressure-sensitive adhesive 30 and conductive adhesive 40 to cover them. Release layer 50 can be made of release film, release paper or any other suitable material.

[0037] Although the conductive adhesive 40 and the antibacterial pressure-sensitive adhesive 30 are described and shown as a stacked double-layer structure in the electrocardiogram electrode 1 according to the first embodiment of the present invention (wherein the antibacterial pressure-sensitive adhesive 30 is disposed on the upper side of the conductive adhesive 40), those skilled in the art will understand that the present invention is not limited thereto, and alternatively, the conductive adhesive 40 and the antibacterial pressure-sensitive adhesive 30 can be formed as a single-layer structure. In a single-layer structure, the conductive adhesive 40 can maintain... Figure 1 As shown, the antibacterial pressure-sensitive adhesive 30 can be formed with a hollow region complementary to the shape of the conductive adhesive 40, so that the conductive adhesive 40 can be embedded into the hollow region of the antibacterial pressure-sensitive adhesive 30. Therefore, the antibacterial pressure-sensitive adhesive 30 fills the hollow portion 43 inside the conductive adhesive and surrounds the outer periphery of the conductive adhesive 40.

[0038] The following will refer to Figure 5 and Figure 6 The electrocardiogram (ECG) electrode according to the second embodiment of the present invention will be described in detail below. The ECG electrode 1a according to the second embodiment of the present invention has a basically the same structure and function as the ECG electrode 1 according to the first embodiment of the present invention. The only difference is the configuration of the conductive adhesive. The similarities will not be repeated, and only the differences will be described.

[0039] Reference Figure 5 and Figure 6 The conductive adhesive 40a can be formed in a generally cross shape and have a hollow portion 43a. The conductive adhesive 40a may include a first extension 44a, a second extension 45a, a third extension 46a, and a fourth extension 47a connected to each other. Preferably, the first extension 44a, the second extension 45a, the third extension 46a, and the fourth extension 47a can be constructed in the same manner, and each extension may have a flange 410a formed at its radially outer end to have an increased surface area, thereby increasing the contact area between the conductive adhesive 40a and the patient's skin to obtain a sufficient electrical detection signal. Adjacent extensions may be spaced apart to form a hollow portion 43a therebetween. Specifically, the hollow portion 43a may include a first hollow portion located between the first extension portion 44a and the second extension portion 45a, a second hollow portion located between the second extension portion 45a and the third extension portion 46a, a third hollow portion located between the third extension portion 46a and the fourth extension portion 47a, and a fourth hollow portion located between the fourth extension portion 47a and the first extension portion 44a.

[0040] When using the ECG electrode 1a, the release layer 50 is first removed from the ECG electrode 1a, and then the exposed antibacterial pressure-sensitive adhesive 30 and conductive adhesive 40a are pressed downwards to adhere tightly to the patient's skin. Because the conductive adhesive 40a has a hollow portion 43a, when the ECG electrode 1a is pressed downwards to adhere to the patient's skin, the upper antibacterial pressure-sensitive adhesive 30 fills the hollow portion 43a of the conductive adhesive 40a. Therefore, the antibacterial pressure-sensitive adhesive 30 not only contacts the patient's skin at the outer periphery of the conductive adhesive 40a, but also contacts the patient's skin inside the conductive adhesive 40a by filling the hollow portion 43a within the conductive adhesive 40a. This results in antibacterial pressure-sensitive adhesive being distributed throughout the center and periphery of the entire ECG electrode 1a, thereby preventing infection of the patient due to contact with the ECG electrode 1a through sufficient antibacterial pressure-sensitive adhesive 30. Furthermore, the hollow portion 43a of the conductive adhesive 40a ensures that the conductive adhesive 40a extends outward to a sufficient area so that the electrocardiogram electrode 1a can obtain a sufficient electrical detection signal through the conductive adhesive 40a. In the electrocardiogram electrode 1a, the ratio of the area of ​​the antibacterial pressure-sensitive adhesive 30 to the total contact area between the electrocardiogram electrode 1a and the patient's skin can be in the range of 60% to 90%, preferably in the range of 67% to 80%. In this case, not only can the electrocardiogram electrode 1a obtain a sufficient electrical detection signal, but it can also provide excellent antibacterial effect for the electrocardiogram electrode 1a.

[0041] Despite Figure 5 The diagram shows an electrocardiogram (ECG) electrode 1a with four extensions and four hollow portions located therebetween. However, those skilled in the art will understand that the present invention is not limited thereto, and the ECG electrode may have other numbers of extensions and hollow portions. Preferably, the multiple extensions and hollow portions may be evenly distributed circumferentially, for example, in... Figure 5 When the electrocardiogram electrode shown has four extensions and four hollow parts, two adjacent extensions can be spaced 90 degrees apart; alternatively, when the electrocardiogram electrode has three extensions and three hollow parts, two adjacent extensions can be spaced 120 degrees apart.

[0042] By using hollow portions evenly distributed in the circumferential direction, the antibacterial pressure-sensitive adhesive 30 can be uniformly filled in each hollow portion along the circumferential direction inside the conductive adhesive 40a, thereby ensuring that the electrocardiogram electrode 1a can provide an effective antibacterial effect in each area. Furthermore, the extensions evenly distributed in the circumferential direction can effectively obtain electrical detection signals in each circumferential area.

[0043] Similar to the electrocardiogram electrode 1 according to the first embodiment of the present invention, in the electrocardiogram electrode 1a according to the second embodiment of the present invention, the conductive adhesive 40a may also be formed as a single layer structure of the antibacterial pressure-sensitive adhesive 30.

[0044] The electrocardiogram electrodes according to various embodiments of this utility model may also include sterilized packaging. Sterilized packaging may include sterilized plastic bags, paper-plastic bags, paper-paper bags, and Tyvek, etc.

[0045] The components of the electrocardiogram electrode according to various embodiments of this utility model (i.e., conductive member, backing, pressure-sensitive adhesive, conductive adhesive, and release layer) can be packaged in sterile packaging after sterilization. Sterilization may include ethylene oxide, gamma rays, or any other sterilization method suitable for conductive adhesives.

[0046] In the electrocardiogram electrodes according to various embodiments of the present invention, the conductive adhesive with a unique configuration can ensure that the conductive adhesive can obtain sufficient detection electrical signals to ensure effective and accurate electrocardiogram detection. On the other hand, the distribution of the antibacterial pressure-sensitive adhesive can be changed to simultaneously fill the interior and exterior of the conductive adhesive, thereby ensuring that the antibacterial pressure-sensitive adhesive can effectively prevent contamination by bacteria and other pathogens in all areas of the electrocardiogram electrode, thereby reducing the risk of infection for patients.

[0047] Exemplary embodiments of the medical detection electrode according to the present invention have been described in detail herein. However, it should be understood that the present invention is not limited to the specific embodiments described and shown above. Various modifications and variations can be made to the present invention by those skilled in the art without departing from its spirit and scope. All such modifications and variations fall within the scope of the present invention. Moreover, all components described herein can be replaced by other technically equivalent components.
