Abstract
Description
Technical field:
[0001] The utility model relates to the technical field of electrocardiogram sensor accessories, in particular to a novel waterproof electrocardiogram sensor patch. Background technology:
[0002] Combine Figure 1 As shown, an ECG sensor 1 is a main component of an ECG device, used for collecting information, and is attached to the patient's skin when in use.
[0003] When the ECG sensor 1 is attached to the patient's skin, it needs to be installed in conjunction with the patch 2 to ensure that the ECG sensor is stably attached to the patient's skin to detect information.
[0004] Currently, the patches used in ECG sensors on the market are as follows Figure 2 As shown, the patch 2 includes a non-woven adhesive tape 21, several conductive cloths 23 fixed to the upper end of the non-woven adhesive tape 21 by double-sided tape 22 and corresponding to the trigger head 11 of the electrocardiograph sensor 1, a PU silver paste circuit 24 arranged on the non-woven adhesive tape 21, a hydrogel 25 fitted with the PU silver paste circuit 24 and used for skin contact, and a release film 26 covering the lower end of the non-woven adhesive tape 21 and covering the hydrogel 25, wherein the middle part of the PU silver paste circuit 24 is also electrically connected to the conductive cloth 23. During use, when the hydrogel 25 contacts the skin, the signal is transmitted to the electrocardiograph sensor 1 through the hydrogel 25, the PU silver paste circuit 24, and the conductive cloth 23, thereby achieving the purpose of detection.
[0005] However, the aforementioned patch 2 adheres tightly to the patient's skin. When the patient sweats, not only does the patch 2 lose its adhesiveness, but it also loses its stable adherence to the skin, causing the patch 2 and the ECG sensor to shift, affecting ECG monitoring. Furthermore, there is no waterproof structure between the patch 2 and the ECG sensor, which to some extent affects the ECG sensor's detection quality.
[0006] In view of this, the inventors propose the following technical solutions. Utility model content:
[0007] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a novel waterproof electrocardiogram sensor patch.
[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions: the new waterproof ECG sensor patch includes an adhesive sticker, several conductive cloths fixed to the upper end of the adhesive sticker by double-sided tape and corresponding to the trigger head of the ECG sensor, a PU silver paste circuit arranged on the adhesive sticker, a hydrogel assembled with the PU silver paste circuit and used for skin contact, and a release film covering the lower end of the adhesive sticker and covering the hydrogel, wherein the middle part of the PU silver paste circuit is also electrically connected to the conductive cloth, the upper end surface of the double-sided tape is adhered and fixed to the ECG sensor to fix the ECG sensor to the upper end of the adhesive sticker; a waterproof ring is provided on the side of the ECG sensor in contact with the double-sided tape, the waterproof ring is adhered and fixed to the double-sided tape, and the waterproof ring is distributed on the periphery of the conductive cloth; the adhesive sticker adopts a waterproof PU adhesive sticker, and the lower end surface of the waterproof PU adhesive sticker is also provided with a hydrocolloid with liquid absorption function, the hydrocolloid is provided with a window, the hydrogel is placed in the window, and the release film also covers the hydrocolloid.
[0009] Furthermore, in the above technical solution, a ring groove is provided on the side of the electrocardiogram sensor in contact with the double-sided tape. The ring groove is distributed around the periphery of the trigger head. The waterproof ring is embedded in the ring groove and surrounds the periphery of the trigger head.
[0010] Furthermore, in the above technical solution, the PU silver paste circuit includes a PU substrate and silver paste arranged on the lower surface of the PU substrate by printing, wherein an extension piece is provided on the outer side of the middle part of the PU substrate, and the PU substrate at the lower end of the extension piece is bent 360 degrees to fit on the upper surface of the PU substrate, so that the silver paste on the lower end surface of the extension piece is exposed on the upper surface of the PU substrate and is used for contact and conduction of the conductive cloth.
[0011] Furthermore, in the above technical solution, a bending line is provided at the junction of the PU substrate and the extension piece.
[0012] Furthermore, in the above technical solution, both ends of the PU silver paste circuit have conductive contacts, and the number of the hydrogels is two, which are fitted one-to-one with the conductive contacts.
[0013] Furthermore, in the above technical solution, a breaking line is provided in the middle of the release film, so that the release film is divided into two to form a first release film and a second release film. The docking positions of the first release film and the second release film are staggered and fitted with each other, and are not fixed with the waterproof PU adhesive tape.
[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: the waterproof PU tape added by the present invention 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 bonding part; at the same time, a hydrocolloid is also provided under the waterproof PU tape, which has an extremely effective liquid absorption function. That is to say, since waterproof PU tape is adopted and hydrocolloid is added, even when the patient sweats, the viscosity of the waterproof PU adhesive in the patch will not be reduced, and the patch and the ECG sensor fixed thereon will not shift, that is, the ECG sensor is ensured to be in its original position, thereby ensuring ECG monitoring. In addition, since the waterproof PU tape 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. In addition, a waterproof ring is provided on the side of the ECG sensor that contacts the double-sided tape. The waterproof ring is fixed to the double-sided tape and is distributed on the periphery of the conductive cloth. In this way, waterproofing can be achieved through the waterproof ring, effectively preventing external water vapor from entering the trigger head of the ECG sensor and the conductive cloth, thereby ensuring the working quality of the ECG sensor.

[0019] The present invention will be further described below with reference to specific embodiments and accompanying drawings.
[0020] See Figure 3-4As shown, a new waterproof ECG sensor patch 3 includes an adhesive patch, several conductive cloths 33 fixed to the upper end of the adhesive patch by double-sided tape 32 and corresponding to the trigger head 11 of the ECG sensor 1, a PU silver paste circuit 34 arranged on the adhesive patch, a hydrogel 35 fitted with the PU silver paste circuit 34 and used for skin contact, and a release film 36 covering the lower end of the adhesive patch and covering the hydrogel 35, wherein the middle part of the PU silver paste circuit 34 is also electrically connected to the conductive cloth 33, and the upper end surface of the double-sided tape 32 is adhered and fixed to the ECG sensor 1 to fix the ECG sensor 1 to the upper end of the adhesive patch; when in use, the release film 36 is torn off the adhesive patch, and when the hydrogel 35 contacts the skin, the signal is transmitted to the trigger head 11 of the ECG sensor 1 through the hydrogel 35, the PU silver paste circuit 34, and the conductive cloth 33, thereby enabling the ECG sensor 1 to achieve the purpose of detection.
[0021] The present invention makes the following improvements to the patch 3: the adhesive sticker adopts a waterproof PU adhesive sticker 31, and the lower end surface of the waterproof PU adhesive sticker 31 is also provided with a hydrocolloid 38 with a liquid absorption function, and the hydrocolloid 38 is provided with a window 381. The hydrogel 35 is placed in the window 381, and the release film 36 also covers the hydrocolloid 38. 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 38 is also provided under the waterproof PU tape 31, which has an extremely effective liquid absorption function. That is to say, since the waterproof PU tape 31 is used and the hydrocolloid 38 is added, even when the patient sweats, the viscosity of the waterproof PU tape 31 in the patch 3 will not be reduced, and the patch 3 and the ECG sensor 1 fixed thereon will not shift, thereby ensuring that the ECG sensor 1 is 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 for the patient. Furthermore, the side of the ECG sensor 1 that contacts the double-sided tape 32 is provided with a waterproof ring 37 , which is adhered to the double-sided tape 32 and extends around the periphery of the conductive fabric 33 . This waterproof ring 37 provides waterproofing, effectively preventing external moisture from entering the trigger head 11 of the ECG sensor 1 and the conductive fabric 33 , thereby ensuring the operating quality of the ECG sensor 1 . Furthermore, the present invention utilizes a PU silver paste circuit 34 for signal transmission, which improves the operating quality of the ECG sensor 1 .
[0022] The structure of the electrocardiogram sensor 1 is as follows Figure 1 shown.
[0023] Among them, the side of the electrocardiogram sensor 1 that contacts the double-sided tape 32 is provided with a ring groove 12, and the ring groove 12 is distributed on the periphery of the trigger head 11. The waterproof ring 37 is embedded in the ring groove 12 and surrounded by the periphery of the trigger head 11. The waterproof ring 37 is also adhered and fixed to the double-sided tape 32, thereby ensuring the stability of the assembly structure. The assembly structure is simple and easy to assemble.
[0024] The PU silver paste circuit 34 includes a PU substrate 341 and a silver paste 342 arranged on the lower surface of the PU substrate 341 by printing, wherein an extension piece 343 is arranged on the outer side of the middle part of the PU substrate 341, and the PU substrate 341 at the lower end of the extension piece 343 is bent 360 degrees to fit on the upper surface of the PU substrate 341, so that the silver paste 342 on the lower end surface of the extension piece 343 is exposed on the upper surface of the PU substrate 341 and is used for contact and conduction of the conductive cloth 33.
[0025] That is to say, the PU silver paste circuit 34 was originally the silver paste 342 on the lower surface of the PU substrate 341, that is, the silver paste 342 was printed on one side, but through the design of the extension piece 343, the upper surface of the PU substrate 341 can also have silver paste 342, thereby achieving the purpose of double-sided silver paste conduction, saving costs, and making it easier to produce.
[0026] A bending line 340 is provided at the junction of the PU substrate 341 and the extension piece 343. When a 360-degree fold is required, the fold can be realized along the bending line 340, which makes the operation easier.
[0027] Both ends of the PU silver paste circuit 34 have conductive contacts, and there are two hydrogels 35 , which are fitted one-to-one with the conductive contacts.
[0028] A tearing line 360 is provided in the middle of the release film 36, which divides the release film 36 into two parts to form a first release film 361 and a second release film 362. The first release film 361 and the second release film 362 are staggered and fitted with each other at the joint positions, and are not adhered and fixed to the waterproof PU tape 31. This makes it easy to tear off the first release film 361 and the second release film 362 relative to the waterproof PU tape 31 later, making the operation easier.
[0029] To sum up, the waterproof PU tape 31 added by the present invention has good water resistance itself, so that it can still maintain excellent performance in a humid or water environment, and can effectively prevent moisture from eroding the bonding part; at the same time, a hydrocolloid 38 is also provided under the waterproof PU tape 31, which has an extremely good liquid absorption function. That is to say, since the waterproof PU tape 31 is used and the hydrocolloid 38 is added, even when the patient sweats, it will not cause the viscosity of the waterproof PU tape 31 in the patch 3 to decrease, and the patch 3 and the ECG sensor 1 fixed thereon will not shift, that is, the ECG sensor 1 is ensured to be in its original position, thereby ensuring ECG monitoring. In addition, since the waterproof PU tape 31 cooperates with the hydrocolloid to contact the patient's skin, 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. In addition, a waterproof ring 37 is provided on the side of the ECG sensor 1 that contacts the double-sided tape 32. The waterproof ring 37 is adhered and fixed to the double-sided tape 32, and the waterproof ring 37 is distributed on the periphery of the conductive cloth 33. In this way, waterproofing can be achieved through the waterproof ring 37, effectively preventing external water vapor from entering the position of the trigger head 11 of the ECG sensor 1 and the conductive cloth 33, thereby ensuring the working quality of the ECG sensor 1.
