This demonstrates that the use of the reinforced patch layer 10 can significantly improve the motion immunity of the electrocardiographic waveform.

Fig. 5 is a schematic diagram showing the relationship between the size and the position of each film layer of the central electric patch of fig. 1, and the vertical lines in fig. 5 show the relationship between the size and the position of each layer. With reference to fig. 1 and fig. 5, in the present embodiment, the adhesive sticker for an electrocardiograph patch further includes a second release layer 52, the second release layer 52 is disposed between the reinforced patch layer 10 and the bonding layer 40, the size of the reinforced patch layer 10 is greater than the size of the second release layer 52, and a projection of the second release layer 52 toward one side of the reinforced patch layer 10 completely falls within the reinforced patch layer 10. The second release layer 52 is provided to make the reinforced patch layer 10 more easily peeled off from the adhesive tape, and the hydrogel sheet 20 and the conductive sheet 30 are not adhered to each other when peeled off, thereby preventing the hydrogel sheet 20 and the conductive sheet 30 from being damaged when peeled off. In step 1 of fig. 2, when the reinforcing patch layer 10 is removed, the second release layer 52 is removed from the adhesive; then, the second release layer 52 is separated from the reinforced patch layer 10; and finally, covering the reinforcing patch layer 10 on the electrocardio patch 60. The second release layer 52 is one of a paper-based double-sided silicon release (double-sided tape lamination) or a PET-based double-sided silicon release, the thickness is 60-160 mu m, and the peeling force is less than 0.1N/25 mm.

With reference to fig. 1 and 5, the reinforced chip mounting layer 10 includes a base portion 11 and a connection portion 12, the second release layer 52 is disposed between the adhesive layer 40 and the base portion 11 of the reinforced chip mounting layer 10, and the connection portion 12 of the reinforced chip mounting layer 10 is adhered to the adhesive layer 40. That is, as shown in fig. 5, the left end edge of the adhesive layer 40 is aligned with the left end edge of the reinforcing patch layer 10, and the connecting portion 12 of the reinforcing patch layer 10 has the same shape as the left end of the adhesive layer 40, so that the connecting portion 12 of the reinforcing patch layer 10 is bonded to the adhesive layer 40. The shape of the second release layer 52 is the same as the shape of the base portion 11 of the reinforced patch layer 10, and the second release layer is aligned with the edge of the base portion 11, so as to ensure that the part of the reinforced patch layer 10 beyond the bonding part is completely covered by the second release layer 52 without adhering other impurities when the adhesive is not used. When the reinforcing patch layer 10 is peeled off, only the base portion 11 may be peeled off from the adhesive tape while the connection portion 12 remains adhered to the adhesive layer 40, which can ensure accurate alignment of the reinforcing patch layer 10 in the subsequent step. In this embodiment, the base material of the reinforcing patch layer 10 is a non-woven fabric, which includes one of polyester, polypropylene, nylon, spandex, acrylic, cotton fiber, wool, silk, hemp fiber, or conductive modification of the above materials, and the back adhesive on the non-woven fabric is one of medical polyacrylate pressure-sensitive adhesive, medical silicone pressure-sensitive adhesive, and medical polyurethane pressure-sensitive adhesive. The thickness of the reinforcing patch layer 10 is 0.1-1 mm.

In this embodiment, the first hydrogel sheet 21, the second hydrogel sheet 22 and the conductive sheet 30 are disposed on the same layer and are disposed between the second release layer 52 and the adhesive layer 40, and since the hydrogel sheet 20 has a certain plasticity, under the adhesive pressure of adhering the film layers, part of the first hydrogel sheet 21 and the second hydrogel sheet 22 can be communicated with each other through the first through hole 431 and the second through hole 432 on both sides of the adhesive layer 40. A gap is formed between the first hydrogel sheet 21 and the second hydrogel sheet 22, and the conductive sheet 30 is disposed in the gap. Because the hydrogel sheet 20 and the silicone rubber layer on the surface of the electrocardiogram patch 60 have excellent adhesion, when the hydrogel sheet 20 and the conductive sheet 30 are simultaneously positioned between the adhesive layer 40 and the electrocardiogram patch 60, only the hydrogel sheet 20 at the first through hole 431 and the second through hole 432 is in contact with the skin, which can reduce the impedance of the electrode-skin interface on one hand, and can ensure the adhesion between the hydrogel and the electrocardiogram patch 60 on the other hand, and can cooperatively reinforce the patch layer 10 to jointly ensure the stability of the electrocardiogram patch 60 in use.

The conductive sheet 30 is made of conductive sponge, so that the conductive sheet 30 has good deformability, and is always in a compressed state under the constraint force of the reinforced patch layer 10, thereby ensuring the connection of the switch 61 of the electrocardiogram patch 60. The thickness of the conducting strip 30 is 1-5mm, the diameter is 8-10mm, and the surface resistance is less than 1 omega/m²Z-axis resistance is less than or equal to 20 omega/m²The compression deformation rate is more than or equal to 60 percent. The conductive sheet 30 may be a conductive sponge covered with metal layers of Ag, Cu, Ni, etc. produced by using a foaming material such as polyurethane, EVA (ethylene-vinyl acetate copolymer), PP (polypropylene), silicone rubber, etc. as a matrix and using a preparation method such as chemical plating, vacuum plating, ion sputtering, vapor deposition, and conductive adhesive coating, etc., and the back adhesive on the conductive sponge is a polyacrylate pressure sensitive adhesive. The size of the conductive sponge is larger than the interval between the two connection terminals of the switch 61 so that the two connection terminals of the switch 61 are simultaneously in contact with the conductive sponge to turn on the switch 61. In the case of the button-type ECG patch 60, the conductive sponge can be eliminated.

The hydrogel sheet 20 is medical hydrogel with a thickness of 0.4-2mm and an AC impedance of less than or equal to 1k omega at 10 Hz. The size of the hydrogel sheet 20 should be larger than the size of the first through hole 431 and the second through hole 432 and smaller than the size of the adhesive layer 40.

Further, in the present embodiment, the adhesive layer 40 includes a paper-based adhesive layer 41 and a nonwoven-based adhesive layer 42, and the nonwoven-based adhesive layer 42 is disposed on a side of the paper-based adhesive layer 41 away from the reinforcing patch layer 10. This ensures a secure bond of the adhesive layer 40 to the hydrogel sheet 20, since the hydrogel sheet 20 is more easily adhered to the paper-based adhesive layer 41; this, in turn, ensures a secure attachment of the patch to the body, since the nonwoven-based adhesive layer 42 is more adhesive to the body skin.

The paper-based adhesive layer 41 includes a first paper-based adhesive layer 411 and a second paper-based adhesive layer 412, a gap is left between the first paper-based adhesive layer 411 and the second paper-based adhesive layer 412, the first hydrogel sheet 21 is attached to the first paper-based adhesive layer 411, and the second hydrogel sheet 22 is attached to the second paper-based adhesive layer 412. The arrangement of the above structure can prevent the short circuit phenomenon caused by the communication of the first hydrogel sheet 21 and the second hydrogel sheet 22 through the paper-based adhesive layer 41 after the water on the hydrogel sheet 20 wets the paper-based adhesive layer 41, thereby ensuring the stability of the signal.

The non-woven fabric base adhesive layer 42 comprises a non-woven fabric base material and a back adhesive thereof, wherein the non-woven fabric base material is one of terylene (polyester), polypropylene fiber, chinlon, spandex, acrylon, cotton fiber, wool, silk and hemp fiber, and the back adhesive is one of medical polyacrylate pressure-sensitive adhesive, medical organosilicon pressure-sensitive adhesive or medical polyurethane pressure-sensitive adhesive. The thickness of the nonwoven fabric-based adhesive layer 42 is 0.1 to 1 mm.

The first release layer 51 is one of a paper-based single-sided silicon release (release-sided tape lamination) or a PET-based single-sided silicon release, the thickness is 25-160 mu m, and the peeling force is less than 0.1N/25 mm.

With continued reference to fig. 1 and 5, the hydrogel sheet 20 and the adhesive layer 40 are both provided with positioning holes 45, and the positioning posts on the electrocardiograph patch 60 extend into the positioning holes 45 to position the electrocardiograph patch 60 on the adhesive patch.

Fig. 6 is a schematic diagram showing heart rates of a human body in various states when the center electrical patch of fig. 1 is attached to an electrocardiograph patch by using a glue, and as shown in fig. 6, the effect of fixing the electrocardiograph patch 60 by using the glue of the electrocardiograph patch provided by the present embodiment is tested. The test scene is daily activities including sitting, walking (slight sports), badminton playing (violent sports) and the like, and the test time is 9h and 14 min. The electrocardiogram wave form diagram of 1 sitting posture, 2 walking, 3 sitting posture, 4 batting and 5 sitting posture is sequentially selected according to the time sequence, the result is shown in figure 6, under the sitting posture and walking states of 3 different time points, characteristic peaks such as P, QRS, T and the like in the electrocardiogram wave form are clear and recognizable, the heart rate is increased from 86 times/min to 112 times/min, and then the heart rate is returned to 86 times/min; under the state of badminton playing, the heart rate is rapidly increased to 161 times/min, at the moment, the characteristic waveform of the electrocardio still has high identification degree, and after the sports is finished, the heart rate is gradually recovered to be normal, and finally, the speed is increased to about 88 times/min. In the whole test time range, the electrocardiographic waveform is continuous and stable without disconnection. The electrocardio waveform and the resting electrocardio in the states of sitting posture, walking and the like are basically consistent, but are basically similar in the state of violent movement, which shows that the adhesive tape in the embodiment has excellent anti-interference capability, and ideally realizes the long-time continuous electrocardio monitoring function of the electrocardio patch 60 in various scenes of sitting posture, walking, ball sports and the like. Particularly, under the badminton motion state accompanied by violent exercise and a large amount of sweating, the electrocardiographic waveform still shows extremely high waveform quality, which means that the application field of the electrocardiographic patch 60 can be expanded to the multi-exercise field, such as electrocardiographic monitoring application under long-distance running, fitness or other ball-type sports scenes.

Fig. 7 is a schematic view showing the structural diagram of each film layer of the adhesive for an ecg patch provided by the second embodiment of the present invention, as shown in fig. 7, the adhesive for an ecg patch provided by the second embodiment of the present invention is substantially the same as the adhesive of the first embodiment, and the difference lies in that, in this embodiment, the first hydrogel sheet 21 and the second hydrogel sheet 22 are both disposed between the adhesive layer 40 and the first release layer 51, that is, the conductive sheet 30 and the hydrogel sheet 20 are disposed on different layers, but disposed on both sides of the adhesive layer 40. The first hydrogel sheet 21 and the second hydrogel sheet 22 are deformed at the first through hole 431 and the second through hole 432 and communicate with both sides of the adhesive layer 40.

In addition, in the present embodiment, the adhesive layer 40 includes a nonwoven fabric-based adhesive layer 42 and a silicone pressure-sensitive adhesive layer 46, the nonwoven fabric-based adhesive layer 42 is disposed on the side of the silicone pressure-sensitive adhesive layer 46 away from the reinforced patch layer 10, that is, the paper-based adhesive layer 41 in the first embodiment is replaced by the silicone pressure-sensitive adhesive layer 46, and when in use, the silicone pressure-sensitive adhesive layer 46 can be directly adhered to the cardiac electric patch 60, so that the hydrogel sheet 20 can be prevented from remaining on the cardiac electric patch 60 while the cardiac electric patch 60 and the adhesive are firmly connected.

At this time, since the silicone pressure-sensitive adhesive layer 46 is tightly adhered to the cardiac patch 60, the first hydrogel sheet 21 and the second hydrogel sheet 22 do not need to be firmly adhered to the cardiac patch 60, and therefore, the size of the cardiac patch can be designed to be smaller, which further saves cost.

In use, the cardiac patch 60 is adhered to the adhesive by the first and

Fig. 9 is a schematic structural view of each film layer of the adhesive for an ecg patch according to the fourth embodiment of the present invention, as shown in fig. 9, the fourth embodiment of the present invention is basically the same as the third embodiment, and the difference is that the radii of the first through hole 431 and the second through hole 432 of the present embodiment are different from the third embodiment. Since the adhesive force between the hydrogel sheet 20 and the cardiac electric patch 60 is relatively large when the diameters of the first through hole 431 and the second through hole 432 are too large, hydrogel residues are easily left on the cardiac electric patch 60, in this embodiment, the radii of the first through hole 431 and the second through hole 432 can be 3-5mm, so that the hydrogel residues on the cardiac electric patch 60 can be prevented on the basis of ensuring the adhesive force between the cardiac electric patch 60 and the hydrogel sheet 20.
