Description

Technical Field

[0001] This utility model relates to the field of biosignal acquisition technology, and in particular to a wearable, low-contact-resistance flexible pulmonary function electrode strip. Background Technology

[0002] Electrode strips are commonly used biosignal acquisition devices, especially for signal acquisition in electrical impedance tomography (EIT). When using electrode strips to acquire signals from target areas of a target organism, the strips are worn on the organism, with multiple electrodes connected to electrode cables. The acquired signals are transmitted via their respective cables to the corresponding terminal devices for processing, analysis, and evaluation. The pulmonary function electrode band has 16 flexible electrodes deployed on the patient's chest surface to capture real-time changes in conductivity across the ventilated areas of the lungs and convert the data into dynamic images. The multi-electrode layout design captures more comprehensive bioimpedance data, significantly improving the accuracy and reliability of the measurements. By analyzing the impedance signals using algorithms, the distribution of airflow in the lung lobes, areas of abnormal flow, and even subtle alveolar ventilation irregularities can be clearly displayed, providing early warning for pulmonary fibrosis and acute exacerbations of COPD. A search of existing Chinese patent technology reveals an "electrode strip" with publication number "CN221949803U". This device can prevent unreliable connections between electrodes and electrode cables from causing accidental disconnections, thus preventing the transmission of complete signals between the electrodes and the main device. This improves the stability of signal transmission between the electrodes and the main device via electrode cables. However, patients often have relatively obvious depressions in their chest cavity, and the existing electrode devices have limited compatibility with the patient's body surface curvature, which can easily lead to interference with local electrode contact, thereby affecting the continuity and fidelity of electrophysiological signal acquisition. Utility Model Content

[0003] Therefore, it is necessary to provide a wearable, low-contact-resistance flexible pulmonary function electrode band, which addresses the issue that existing electrode devices have limited compatibility with the patient's body surface due to the relatively obvious indentation in the chest cavity of common patients, which can easily lead to interference with local electrode contact and thus affect the continuity and fidelity of electrophysiological signal acquisition.

[0004] A wearable, low-contact-resistance flexible pulmonary function electrode band includes: a silicone elastic band, a connecting buckle fixedly connected to one side of the silicone elastic band, and multiple electrode pads fixedly connected to the side of the silicone elastic band near the connecting buckle, the multiple electrode pads being evenly distributed in a straight line along the surface of the silicone elastic band; and an adhesion mechanism installed on both sides of the silicone elastic band; wherein the adhesion mechanism includes multiple silicone adhesive plates installed on one side of the silicone elastic band, the silicone adhesive plates being located between adjacent electrode pads, a conductive adhesive retention component being adhered to the side of the silicone adhesive plate away from the silicone elastic band, the surface of the conductive adhesive retention component extending to both ends of the adjacent electrode pads and fixedly connected to the surface of the silicone elastic band, and multiple positioning components fixedly connected to the other side of the silicone elastic band, the multiple positioning components being evenly distributed in a straight line along the surface of the silicone elastic band, wherein two of the positioning components have recessed contact components connected to their surfaces, the surface of the recessed contact components contacting the other side of the silicone elastic band.

[0005] In one embodiment, the recessed abutment component includes a binding strap disposed on the surfaces of two of the positioning components. Two first Velcro straps are fixedly connected to the middle of the surface of the binding strap away from the silicone elastic band, and a second Velcro strap is fixedly connected to the end of the surface of the binding strap away from the silicone elastic band. The second Velcro strap is bonded to the adjacent first Velcro strap, and an abutment cavity is fixedly connected to the other side of the binding strap.

[0006] In one embodiment, the conductive adhesive retention assembly includes two conductive adhesive retention strips fixedly connected to the surface of the silicone elastic strip, and a plurality of conductive adhesive storage blocks are disposed between the two conductive adhesive retention strips. The conductive adhesive storage blocks are connected to the surface of the adjacent silicone adhesive plate. The conductive adhesive storage block includes a conductive adhesive bag disposed between two electrode plates. An adhesive patch is fixedly connected to the surface of the conductive adhesive bag near the surface of the silicone elastic band. The adhesive patch is adhered to the surface of the adjacent silicone adhesive plate. A filling valve is embedded in one end of the conductive adhesive bag. Multiple discharge holes are respectively opened on the two inclined surfaces of the conductive adhesive bag.

[0007] In one embodiment, the conductive adhesive retention strip includes a silicone telescopic strip fixedly connected to the surface of the silicone elastic strip. A plurality of first silicone sheets are fixedly connected to the side of the silicone telescopic strip away from the silicone elastic strip. A second silicone sheet is disposed on the inner side of the first silicone sheet. The second silicone sheet is fixedly connected to the surface of the silicone telescopic strip and is located between two first silicone sheets.

[0008] In one embodiment, the positioning component includes a plurality of positioning cloth rings fixedly connected to the surface of the silicone elastic band. The plurality of positioning cloth rings are evenly distributed in a straight line along the surface of the silicone elastic band. A plurality of plastic frames are provided on the side of the silicone elastic band away from the electrode sheet. The positioning cloth rings are sleeved on the surface of the adjacent plastic frames, and the surface of the plastic frames is in contact with the surface of the adjacent binding strap.

[0009] In one embodiment, the abutment cavity includes a fixing connecting plate adhered to the other side of the binding strap, and two silicone cone plates are fixedly connected to the side of the fixing connecting plate near the silicone elastic band, and an elastic stretch membrane is fixedly connected to the surface of the silicone cone plates away from the fixing connecting plate.

[0010] In one embodiment, the discharge holes on both sides are staggered, and a plurality of sealing plates are fixedly connected to the inner wall of the conductive plastic bag, with the surface of the sealing plates extending into the interior of the adjacent discharge holes.

[0013] In one embodiment, the plastic frame includes a central rod located inside the positioning cloth ring, the end of which extends through to the outside of the positioning cloth ring and is fixedly connected to two side rods.

[0014] The aforementioned wearable low-contact-resistance flexible pulmonary function electrode band, through the setting of a recessed contact component, allows the surface of the silicone elastic band to conform to the curve of the patient's body surface. The device is embedded in the recessed area of ​​the patient's chest cavity through the contact cavity, and the silicone cone plate adapts to the curvature of the body surface through the difference in width and narrow cross sections, dispersing local pressure. When the chest cavity is compressed by breathing, the gas pushes the elastic membrane to expand outward, and in turn pushes the silicone elastic band to move towards the body surface, so that the silicone elastic band keeps the electrode pads tightly attached to the skin during the detection process, ensuring the continuity and fidelity of the electrophysiological signal acquisition. The device features a conductive adhesive retention component that prevents adhesive backflow by incorporating internal silicone flaps. Staggered discharge holes on both sides ensure even filling of the electrode gaps. A first and second silicone sheet at the electrode end overlaps when bent to seal the conductive adhesive, preventing it from flowing outwards. This ensures the conductive adhesive remains in the gap between the electrode and the patient's skin, guaranteeing the continuity and fidelity of electrophysiological signal acquisition.

[0023] The following is combined Figures 1-11This invention describes a wearable, low-contact-resistance flexible pulmonary function electrode band, comprising: a silicone elastic band 100, with a connecting buckle 110 fixedly connected to one side of the silicone elastic band 100; a plurality of electrode pads 200 fixedly connected to the side of the silicone elastic band 100 near the connecting buckle 110, the plurality of electrode pads 200 being uniformly distributed in a straight line along the surface of the silicone elastic band 100; and an adhesion mechanism 300 mounted on both sides of the silicone elastic band 100; wherein the adhesion mechanism 300 includes a plurality of silicone adhesive plates 340 mounted on one side of the silicone elastic band 100, the silicone adhesive plates 340 being located in a relatively... Between adjacent electrode sheets 200, a conductive adhesive retention component 320 is bonded to the side of the silicone adhesive plate 340 away from the silicone elastic band 100. The surface of the conductive adhesive retention component 320 extends to both ends of the adjacent electrode sheets 200 and is fixedly connected to the surface of the silicone elastic band 100. Multiple positioning components 330 are fixedly connected to the other side of the silicone elastic band 100. The multiple positioning components 330 are evenly distributed in a straight line along the surface of the silicone elastic band 100. Among them, the surfaces of two positioning components 330 are connected to recessed contact components 310, and the surface of the recessed contact components 310 contacts the other side of the silicone elastic band 100. like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 10 As shown, the recessed abutment component 310 includes a binding strap 311 disposed on the surface of two of the positioning components 330. Two first hook and loop fasteners 312 are fixedly connected to the middle of the surface of the binding strap 311 away from the silicone elastic band 100. A second hook and loop fastener 313 is fixedly connected to the end of the surface of the binding strap 311 away from the silicone elastic band 100. The second hook and loop fastener 313 is bonded to the adjacent first hook and loop fastener 312. An abutment cavity 314 is fixedly connected to the other side of the binding strap 311. The contact cavity 314 includes a fixed connecting plate 3142 bonded to the other side of the binding strap 311. Two silicone cone plates 3143 are fixedly connected to the side of the fixed connecting plate 3142 near the silicone elastic band 100. An elastic stretching membrane 3141 is fixedly connected to the surface of the silicone cone plate 3143 away from the fixed connecting plate 3142. The surface of the silicone cone plate 3143 near the fixed connecting plate 3142 is the wide part, and the surface of the silicone cone plate 3143 near the elastic stretching membrane 3141 is the narrow part. The longitudinal section of the silicone cone plate 3143 is conical. During use, when the patient binds the silicone elastic band 100 to the chest, the binding band 311 is passed through one of the plastic frames 332, and the second Velcro 313 at the end is attached to the surface of the adjacent first Velcro 312 to form a stable bond. At this time, the contact cavity 314 is located in the depression of the patient's chest. The silicone elastic band 100 deforms due to the contact of the contact cavity 314, which allows the electrode sheet 200 to adhere to the patient's body surface. Depending on the degree of chest cavity depression on the patient's body surface, the other end of the binding band 311 is passed through the plastic frame 332, so that the contact cavity 314 is located in the middle of the chest cavity depression. The fixed connecting plate 3142 is coated with an adhesive and can be manually removed and replaced. The fixed connecting plate 3142 and the two silicone cone plates 3143 form a cavity. Since the elastic stretching membrane 3141 is made of flexible and stretchable elastic silicone, the cavity can be compressed, causing the internal space of the cavity to decrease. The gas resists the elastic stretching membrane 3141 and deforms, causing the elastic stretching membrane 3141 to push the silicone elastic band 100 closer to the patient's body surface, so that the electrode sheet 200 fits the patient's body surface, improving the accuracy of electrode detection. like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the conductive adhesive retention assembly 320 includes two conductive adhesive retention strips 322 fixedly connected to the surface of the silicone elastic band 100, and a plurality of conductive adhesive storage blocks 321 disposed between the two conductive adhesive retention strips 322. The conductive adhesive storage blocks 321 are connected to the surface of adjacent silicone adhesive plates 340. The conductive adhesive storage block 321 includes a conductive adhesive bag 3211 disposed between two electrode plates 200. An adhesive patch 3215 is fixedly connected to the surface of the conductive adhesive bag 3211 near the surface of the silicone elastic band 100. The adhesive patch 3215 is bonded to the surface of the adjacent silicone adhesive plate 340. A filling valve 3212 is embedded in one end of the conductive adhesive bag 3211. A plurality of discharge holes 3213 are respectively opened on the two inclined surfaces of the conductive adhesive bag 3211. The two discharge holes 3213 are staggered on both sides. Multiple sealing pieces 3214 are fixedly connected to the inner wall of the conductive plastic bag 3211. The surface of the sealing piece 3214 extends into the interior of the adjacent discharge hole 3213. The sealing piece 3214 includes a connecting ring 32141 fixedly connected to the inner wall of the conductive plastic bag 3211. Multiple silicone flaps 32142 are fixedly connected to the inner wall of the connecting ring 32141. During use, medical staff can manually press the surface of the silicone elastic band 100 to squeeze the conductive rubber bag 3211. At this time, the conductive rubber stored inside the conductive rubber bag 3211 flows through the sealing piece 3214 to the outside of the conductive rubber bag 3211, so that the gap between the electrode piece 200 and the patient's body surface is filled with conductive rubber. The structure of the silicone flap 32142 is similar to the structure of a heart valve, so that the conductive rubber inside the conductive rubber bag 3211 is not allowed to flow back after being squeezed out. Furthermore, the conductive plastic bag 3211 can be made of inelastic and deformable plastic paper. After the conductive plastic bag 3211 is squeezed and the conductive adhesive is discharged, the conductive plastic bag 3211 will not reset, thus avoiding the conductive plastic bag 3211 from affecting the adhesion between the electrode pad 200 and the patient's body surface after resetting. Since the discharge holes 3213 on both sides are staggered, when the electrode pad 200 is attached to the patient's body surface, the conductive adhesive squeezed out by the second Velcro 313 on both sides is relatively evenly filled into the gap between the patient's body surface and the electrode pad 200. The conductive bag 3211 can be a reusable device. It is bonded to the silicone adhesive plate 340 by the adhesive tape 3215. After use, the conductive bag 3211 can be removed and the conductive adhesive can be injected back into the conductive bag 3211 through the filling valve 3212. The conductive adhesive retention strip 322 includes a silicone telescopic strip 3221 fixedly connected to the surface of the silicone elastic strip 100. A plurality of first silicone sheets 3222 are fixedly connected to the side of the silicone telescopic strip 3221 away from the silicone elastic strip 100. A second silicone sheet 3223 is provided on the inner side of the first silicone sheet 3222. The second silicone sheet 3223 is fixedly connected to the surface of the silicone telescopic strip 3221 and is located between two first silicone sheets 3222. Multiple first silicone sheets 3222 and second silicone sheets 3223 are connected to the end of the electrode sheet 200 by a silicone telescopic strip 3221. When the conductive adhesive is filled into the gap between the patient's body surface and the electrode sheet 200, the flow of the adhesive is restricted by the action of the first silicone sheet 3222, reducing the flow of the conductive adhesive with the body surface. Since the second silicone sheet 3223 is located inside the first silicone sheet 3222 and between the two first silicone sheets 3222, when the silicone elastic band 100 is bent, the second silicone sheet 3223 overlaps with the first silicone sheet 3222. Furthermore, the longitudinal cross-sections of both the first silicone sheet 3222 and the second silicone sheet 3223 are L-shaped, which can effectively seal both ends of the electrode sheet 200, making it difficult for the conductive adhesive on the patient's body surface to flow. like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 11 As shown, the positioning component 330 includes multiple positioning cloth rings 331 fixedly connected to the surface of the silicone elastic band 100. The multiple positioning cloth rings 331 are evenly distributed in a straight line along the surface of the silicone elastic band 100. Multiple plastic frames 332 are provided on the side of the silicone elastic band 100 away from the electrode sheet 200. The positioning cloth rings 331 are sleeved on the surface of the adjacent plastic frames 332. The surface of the plastic frames 332 is in contact with the surface of the adjacent binding strap 311. The plastic frame 332 includes a central rod 3321 located inside the positioning cloth ring 331. The end of the central rod 3321 extends to the outside of the positioning cloth ring 331 and is fixedly connected to two side rods 3322. The plastic frame 332 provides a positioning function for the binding strap 311. The surface of the side rods 3322 can be set to a frosted state to increase the friction between the side rods 3322 and the surface of the binding strap 311. Furthermore, the plastic frame 332 is made of plastic, which reduces interference with the electrode sheet 200 and ensures the accuracy of the detection.

[0024] A method for using a wearable, low-contact-resistance flexible pulmonary function electrode band: A1. Adhere the conductive adhesive storage block 321 to the surface of the silicone adhesive plate 340, and put the silicone elastic band 100 on the patient's chest so that the electrode pad 200 is in contact with the patient's body surface. As needed for the specific location to be detected, the medical staff assists the patient in making manual adjustments. Fasten the connecting buckle 110 to the other end of the silicone elastic band 100. While keeping the silicone elastic band 100 relatively stable on the patient's body surface, the silicone elastic band 100 also maintains a certain degree of elasticity. A2. First, pass the binding strap 311 through one of the plastic frames 332, and attach the second Velcro 313 at the end to the surface of the adjacent first Velcro 312 to form a stable bond. At this time, the contact cavity 314 can be located in the depression of the patient's chest. Then, pass the other end of the binding strap 311 through the plastic frame 332 to keep the contact cavity 314 close to the depression of the patient's chest. A3. Medical staff can press the silicone elastic band 100 away from the patient's body surface, causing the conductive adhesive inside the conductive adhesive storage block 321 to overflow. After the conductive adhesive overflows, medical staff can press or push the silicone elastic band 100 laterally to generate a moving tendency, which helps to expel air bubbles from the silicone elastic band 100 and the patient's body surface, so that the electrode pad 200 and the patient's body surface are fully filled with conductive adhesive for testing.

[0025] When in use, the device works as follows: A silicone telescopic strip 3221 connects multiple first silicone sheets 3222 and second silicone sheets 3223 to the ends of the electrode sheet 200. The flow of the adhesive is restricted by the first silicone sheets 3222. When the silicone elastic band 100 bends, the second silicone sheets 3223 overlap with the first silicone sheets 3222, effectively sealing both ends of the electrode sheet 200 and preventing the conductive adhesive from flowing onto the patient's skin. Medical staff manually press against the surface of the silicone elastic band 100, causing the silicone... The elastic band 100 squeezes the conductive rubber bag 3211. The conductive rubber stored inside the conductive rubber bag 3211 flows out of the conductive rubber bag 3211 through the sealing piece 3214. The gap between the electrode piece 200 and the patient's body surface is filled with conductive rubber. The conductive rubber bag 3211 is squeezed out by the conductive rubber. The openings of the discharge holes 3213 on both sides are staggered. When the electrode piece 200 is attached to the patient's body surface, the conductive rubber squeezed out by the second Velcro 313 on both sides fills the gap between the patient's body surface and the electrode piece 200 relatively evenly. When the patient binds the silicone elastic band 100 to the chest area, the binding band 311 is passed through a plastic frame 332, and the second Velcro 313 at the end of the binding band 311 is attached to the surface of the adjacent first Velcro 312 to form a stable bond. The contact cavity 314 is located in the depression of the patient's chest. The contact cavity 314 deforms due to the contact with the silicone elastic band 100, causing the electrode plate 200 to adhere to the patient's body surface. Depending on the degree of chest cavity depression on the patient's body surface, the other end of the binding band 311 is passed through the plastic frame 332. The contact cavity 314 is located in the middle of the chest cavity depression. A cavity is formed by the fixed connecting plate 3142 and two silicone cone plates 3143. When the cavity is compressed, the internal space of the cavity decreases, and the gas deforms due to the contact with the elastic stretching membrane 3141. The elastic stretching membrane 3141 pushes the silicone elastic band 100 closer to the patient's body surface, causing the electrode plate 200 to adhere to the patient's body surface.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0027] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
