Description

Technical field:

[0001] The utility model relates to the technical field of electrode sheets, in particular to a disposable waterproof electrode sheet. Background technology:

[0002] Disposable ECG electrodes are disposable electrodes. ECG electrodes are the connection ports of ECG equipment and are attached to the patient's skin when in use.

[0003] Combine Figure 1-3 The figure shows an ECG electrode sheet 1 in the prior art, which includes a non-woven adhesive tape 11, a double-sided adhesive tape 12 disposed on the non-woven adhesive tape 11 and used to securely connect to the sensor 2, a conductive fabric 13 disposed on the double-sided adhesive tape 12 and corresponding to the electrostatic release block 21 on the sensor 2, a hydrogel 14 disposed at the center hole 111 of the non-woven adhesive tape 11 and used to correspond to the trigger area 22 of the sensor 2, and a release film 15 covering the lower end surface of the non-woven adhesive tape 11, the release film 15 also covering the hydrogel 14. During use, the release film 15 is torn away from the non-woven adhesive tape 11, and then adhered and fixed to the patient's skin through the non-woven adhesive tape 11. The hydrogel 14 contacts the patient's skin, and the trigger area 22 of the sensor 2 forms an induction with the patient's skin through the hydrogel 14, thereby achieving ECG monitoring.

[0004] However, the above-mentioned disposable electrode sheet still has some shortcomings when used: the above-mentioned disposable electrode sheet is in close contact with the patient's skin. When the patient sweats, not only does it cause the viscosity of the electrode sheet to decrease, that is, the non-woven adhesive patch 11 cannot be stably attached to the skin, thereby causing the electrode sheet to shift, affecting ECG monitoring. On the other hand, when the patient sweats, since the non-woven adhesive patch 11 directly adheres to the skin, it is easy to cause the patient's skin allergies, further affecting the patient's ECG monitoring.

[0005] In view of this, the inventors propose the following technical solutions. Utility model content:

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a disposable waterproof electrode sheet for solving the technical problem that when a patient sweats, not only the viscosity of the electrode sheet is reduced, thereby causing the electrode sheet to shift and affecting ECG monitoring, but also sweating easily causes skin allergies in the patient, further affecting ECG monitoring of the patient.

[0007] In order to solve the above technical problems, the present utility model adopts the following technical solution: the disposable waterproof electrode sheet includes a sticker, a double-sided tape arranged on the upper end surface of the sticker and used to be fixedly connected to the sensor, a conductive cloth arranged on the double-sided tape and corresponding to the electrostatic release block on the sensor, a hydrogel arranged at the center hole of the sticker and used to correspond to the trigger area of ​​the sensor and to enhance the collected signal, and a release film covering the lower end surface of the sticker, the release film also covers the hydrogel, the sticker is a waterproof PU tape, and the lower end surface of the waterproof PU tape is also provided with a hydrocolloid with liquid absorption function, the hydrocolloid is distributed on the periphery of the hydrogel, and the release film also covers the hydrocolloid.

[0008] Furthermore, in the above technical solution, a release paper is also attached to the edge of the lower end surface of the waterproof PU tape, and the release film is also covered on the release paper without adhesion between them.

[0009] Furthermore, in the above technical solution, a U-shaped notch is provided on the outer side of the release film at a position corresponding to the release paper for easy tearing.

[0010] Furthermore, in the above technical solution, the hydrocolloid is annular and sheet-like, and a window is provided in the middle of the hydrocolloid, and the hydrogel is exposed in the window.

[0011] Furthermore, in the above technical solution, the outer diameter of the hydrocolloid is smaller than the outer diameter of the waterproof PU tape.

[0012] Furthermore, in the above technical solution, the outer diameter of the hydrocolloid is less than half of the outer diameter of the waterproof PU tape.

[0013] Furthermore, in the above technical solution, the waterproof PU tape, double-sided tape, and hydrocolloid are all in a ring shape.

[0014] After adopting the above technical solution, the present invention has the following advantages compared with the prior art: the present invention uses waterproof PU tape for adhesion and fixation to the patient's skin. The waterproof PU tape has excellent elasticity, allowing it to adapt to various complex environments and conditions during the bonding process, providing good adhesion to both soft and hard materials. The waterproof PU tape has excellent water resistance, allowing it to maintain excellent performance in humid or watery environments and effectively prevent moisture from eroding the bonding area. At the same time, a hydrocolloid is also provided below the waterproof PU tape, which has an excellent liquid absorption function. In other words, because the waterproof PU tape is used and the hydrocolloid is added, even if the patient sweats, the adhesion of the electrode sheet will not be reduced, and the electrode sheet will not shift, thus ensuring that the electrode sheet remains in its original position, thereby ensuring ECG monitoring. In addition, because the waterproof PU tape and the hydrocolloid contact the patient's skin, it ensures good skin adhesion and good rebound effect, avoiding the problem of skin allergies and further ensuring the quality of ECG monitoring for the patient.

[0020] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0021] See Figure 3-5 As shown, a disposable waterproof electrode sheet is used together with a sensor.

[0022] The waterproof electrode sheet 3 of the present invention comprises an adhesive patch, a double-sided adhesive tape 32 disposed on the upper end surface of the adhesive patch for fixed connection with the sensor 2, a conductive fabric 33 disposed on the double-sided adhesive tape 32 and corresponding to the electrostatic release block 21 on the sensor 2, a hydrogel 34 disposed in the center hole 311 of the adhesive patch for corresponding to the trigger area 22 of the sensor 2 and for enhancing the collected signal, and a release film 35 covering the lower end surface of the adhesive patch. The release film 35 also covers the hydrogel 34. The adhesive patch is a waterproof PU tape 31. The lower end surface of the waterproof PU tape 31 is also provided with a hydrocolloid 36 with a liquid-absorbing function. The hydrocolloid 36 is distributed around the periphery of the hydrogel 34, and the release film 35 also covers the hydrocolloid 36. In other words, the present invention uses the waterproof PU tape 31 for adhesion and fixation to the patient's skin. The waterproof PU tape 31 itself has good elasticity, allowing it to adapt to various complex environments and conditions during the bonding process. The waterproof PU tape 31 can provide good bonding effect for both soft and hard materials. The waterproof PU tape 31 itself has good water resistance, so that it can still maintain excellent performance in a humid or water environment, and can effectively prevent moisture from eroding the adhesive part; at the same time, a hydrocolloid is also provided under the waterproof PU tape 31, and the hydrocolloid has an extremely good liquid absorption function. That is to say, since the waterproof PU tape 31 is used and the hydrocolloid is added, even when the patient sweats, the viscosity of the electrode sheet will not be reduced, and the electrode sheet will not shift, that is, the electrode sheet is guaranteed to be in its original position, thereby ensuring ECG monitoring. In addition, since the waterproof PU tape 31 is in contact with the patient's skin in combination with the hydrocolloid, it ensures good skin fit and good rebound effect, avoids the problem of skin allergies in the patient, and further ensures the quality of ECG monitoring of the patient.

[0023] In order to be able to tear off the release film 35 from the lower end surface of the waterproof PU tape 31 more conveniently and quickly, the following design is also made: a release paper 37 is also attached to the edge of the lower end surface of the waterproof PU tape 31, and the release film 35 is also covered on the release paper 37, and there is no adhesion between them. That is to say, the present invention adds a small piece of release paper 37 at the edge of the lower end surface of the waterproof PU tape 31 and the release film 35, so that the edge of the release film 35 is not adhered to the edge of the lower end surface of the waterproof PU tape 31, and the release film 35 is also not adhered to the release paper 37, that is, the release paper 37 separates the edge of the release film 35 relative to the edge of the lower end surface of the waterproof PU tape 31, so that the user can directly flip up the edge of the release film 35 relative to the edge of the lower end surface of the waterproof PU tape 31, and then pinch the edge of the release film 35 to tear the release film 35 off relative to the waterproof PU tape 31, so as to achieve the purpose of tearing the release film 35 off relative to the lower end surface of the waterproof PU tape 31 more conveniently and quickly.

[0024] Among them, a U-shaped notch 351 for easy tearing is set at the position of the release paper 37 on the outside of the release film 35, which makes it easier for fingers to pinch the edge of the release film 35, and then more conveniently and quickly tear the release film 35 off from the lower end surface of the waterproof PU tape 31.

[0025] The hydrocolloid 36 is annular and sheet-like. A window 361 is provided in the middle of the hydrocolloid 36 , and the hydrogel 34 is exposed in the window 361 .

[0026] The outer diameter of the hydrocolloid 36 is smaller than the outer diameter of the waterproof PU tape 31. Specifically, the outer diameter of the hydrocolloid 36 is less than half of the outer diameter of the waterproof PU tape 31, so that the present invention can be stably attached to the patient's skin through the waterproof PU tape 31.

[0027] The waterproof PU tape 31 , the double-sided tape 32 , and the hydrocolloid 36 are all in a ring shape.

[0028] In summary, the present invention uses a waterproof PU tape 31 for attachment to the patient's skin. The waterproof PU tape 31 itself has good elasticity, allowing it to adapt to various complex environments and conditions during the bonding process. Whether it is for soft materials or hard materials, the waterproof PU tape 31 can provide good bonding effect. The waterproof PU tape 31 itself has good water resistance, allowing it to maintain excellent performance in humid or watery environments and effectively prevent moisture from eroding the bonding area. At the same time, a hydrocolloid is also provided below the waterproof PU tape 31. The hydrocolloid has an excellent liquid absorption function. In other words, because the waterproof PU tape 31 is used and the hydrocolloid is added, even if the patient sweats, the viscosity of the electrode sheet will not be reduced, and the electrode sheet will not shift, that is, the electrode sheet is kept in its original position, thereby ensuring ECG monitoring. In addition, because the waterproof PU tape 31 and the hydrocolloid are in contact with the patient's skin, it ensures good skin adhesion and good rebound effect, avoiding the problem of causing skin allergies in the patient, further ensuring the quality of ECG monitoring for the patient.
