[0028] DETAILED DESCRIPTION

[0029] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] In the actual process of surface electrode mapping, installing electrodes on the human torso is a time-consuming and labor-intensive process, and may cause discomfort and adverse reactions such as skin allergies to the person being tested.

[0032] In order to solve this technical problem, the present invention proposes a vest device for measuring the electromotive force on the body surface, see Figures 1 to 7The vest device for measuring body surface electromotive force proposed in the present invention includes a vest body 11, a shoulder strap assembly 12 arranged on the upper part of the vest body 11, and a vest hem 13 arranged on the lower part of the vest body 11. A center seam zipper portion 111 is also provided in the middle of the above-mentioned vest body 11.

[0033] A lining member 14 is provided on the inner surface of the vest body 11. In order to prevent the human body from directly contacting other parts of the vest device, the coverage of the lining member 14 is slightly larger than that of the vest device, that is, the area of ​​the unfolded plane of the lining member 14 is larger than the area of ​​the unfolded plane of the vest body 11. The lining member 14 is replaceable. When all the external electrode caps are removed, the lining member 14 can also be removed. In addition, a plurality of lining through holes 140 are evenly provided on the lining member 14, and each lining through hole 140 corresponds to the position of the electrode stem 211. The shoulder strap assembly 12 includes a first shoulder strap 121 and a second shoulder strap 122 which are arranged opposite to each other.

[0034] In order to avoid the problem of misalignment when the staff replaces the lining in the vest device, in the present invention, a marking portion is provided at the top of each row of lining through holes 140. Specifically, the above-mentioned marking portion includes a first marking portion 141, a second marking portion 142, a third marking portion 143 and a fourth marking portion 144. Figure 2 It can be seen that the first marking portion 141 is located at the right armpit of the vest body 11, the second marking portion 142 is located at the front chest of the vest body 11, the third marking portion 143 is located at the left armpit of the vest body 11, and the fourth marking portion 144 is located at the back of the vest body 11.

[0035] The liner through holes 140 are arranged in multiple rows and are evenly arranged in the vertical direction. A marking portion is provided at the top of each row of liner through holes 140. Figure 2 The first marking part 141 corresponds to a row of liner through holes 140, and the letter marked is "A"; the second marking part 142 corresponds to multiple rows of liner through holes 140, and the letters marked are "B, C, D, E, F, G, H, I, J, K"; the third marking part 143 corresponds to a single row of liner through holes 140, and the letter marked is "L"; the fourth marking part 144 corresponds to multiple rows of liner through holes 140, and the letters marked are "M, N, O, P, Q, R, S, T, U, V". It can be understood that the above-mentioned setting has the effect of marking and identification, which is convenient for setting the electrodes in the vest device.

[0036] For the vest body 11 mentioned above, the vest body 11 includes a plurality of vest units 110 that are continuously and evenly arranged, and an electrode member 21 is disposed in each of the vest units 110 .

[0037] The vest unit 110 includes a relatively arranged vest unit outer layer 1101 and a vest unit inner layer 1102, a flexible filler layer 1103 is arranged in the vest unit 110, and an inner and outer layer stitching part 112 is arranged between two adjacent vest unit parts. The vest unit outer layer and the inner layer of the vest unit 110 are made of nylon, spandex or nylon material, and the flexible filler layer is a material with expansion properties such as latex or sponge, but the expansion property should not be too strong, which will make the human body feel oppressive. The vest device proposed in the present invention utilizes the combination of the vest unit outer layer 1101, the vest unit inner layer 1102 and the flexible filler layer 1103, and forms a protrusion under the pulling action of the inner and outer layer stitching part 112 and the stitching reinforcement patch 31 to push the electrode member 21 toward the human body to achieve the purpose of good contact with the skin. At the same time, the entire vest device is soft and breathable, and the body feels comfortable. The aforementioned seam reinforcement patch 31 is used to prevent the seam from being torn and perforated and from being squeezed into the filler of the vest.

[0038] The electrode member 21 mentioned above penetrates the vest unit 110 in the radial direction, and the electrode member 21 includes an electrode body 210, and an electrode stem 211 is arranged inside the electrode body 210. It should be supplemented that the electrode body 210 mentioned above is a light and hard material, similar to the shape of a peanut. The electrode body 210 mentioned above has two functions: one is to prevent the electrode stem from swaying in the soft filling material, so that the electrode cap 212 always points to the human body and plays a directional role; the second is to prevent the slender electrode stem 211 from swinging in the filling material, gradually expanding the holes in the filling material, and extending the service life of the vest device. It should be supplemented here that the electrode members 21 mentioned above can be evenly distributed in the vertical direction, can be evenly distributed in the horizontal direction, or can be evenly arranged in a straight line direction at any angle, and can also be distributed in a honeycomb shape.

[0039] Specifically, the electrode component 21 includes an electrode stem 211, an electrode cap 212 provided at one end of the electrode stem 211, and an electrode wire 213 provided at the other end of the electrode stem 211. In the present invention, the above-mentioned electrode cap 212 protrudes from the outside of the inner surface of the lining component 14, the electrode cap 212 is used to directly contact the user's skin, and the electrode wire 213 is electrically connected to the sampling device through the signal cable 16. It should also be noted that in the actual production process, in order to facilitate the distinction and positioning of each electrode component 21, each electrode component corresponds to a symbol mark for distinction. In this solution, the "row number + column number" method is used to distinguish the electrode components. If the symbol font is very small, it can be printed near the electrode component.

[0040] See also Figure 5The electrode stem 211 includes an electrode stem head 2111, an electrode stem neck 2112, an electrode stem disk 2113 and an electrode stem tail 2114 which are sequentially connected. In the actual assembly process, the electrode stem head 2111 is arranged inside the electrode cap 212, the electrode stem neck 2112 is inserted into the lining through hole 140, the electrode stem disk 2113 is located between the lining member 14 and the vest body 11, and the electrode stem tail 2114 is inserted into the vest unit 110. The electrode stem material is a good conductor of electricity that is light, strong, durable and not easy to rust. In order to reduce weight, the electrode stem can be made into a hollow tubular structure, and different parts of the electrode stem can also be made of different materials. Known materials and components suitable for making electrode stems are listed as follows (but not limited to these materials and components): conductive plastic, silver, silver chloride, platinum, gold, nickel, chromium, palladium, rhodium, iridium, osmium, ruthenium, etc.

[0041] The electrode stem tail 2114 is electrically connected to the electrode wire 213, and a wire insulation layer 2131 is provided on the periphery of the electrode wire 213, and the electrode wire 213 is electrically connected to the signal cable 16. A cable socket 161 is provided at the free end of the signal cable 16, and the cable socket 161 is used to electrically connect to the sampling device. The electrode stem head 2111 is in the shape of an expanded ball, which is used to be combined with the electrode cap 212. The electrode stem neck 2112 passes through the lining through hole 140 to position the lining member 14. The electrode stem disk 2113 and the electrode body 210 together press the flexible packing layer 1103 in the vest, and the tension of the flexible packing layer 1103 enables the electrode member 21 to be evenly distributed. The electrode stem tail 2114 is combined with the electrode wire 213, so that the human body current obtained by the electrode cap 212 can be transmitted to the electrode wire 213.

[0042] See also Figure 6 The electrode cap 212 includes a block-shaped electrode cap body 2120 and elastic pressing parts 2121 arranged on both sides of the electrode cap body 2120. An electrode cap plug hole 2122 is provided in the electrode cap body 2120. The electrode stem head 2111 is arranged in the electrode cap plug hole 2122. The elastic pressing part 2121 is in elastic pressing contact with the outer surface of the lining member 14. The electrode cap 212 is a part that is in direct contact with the human body. It can be removed for high temperature or chemical disinfection and can be reused. The electrode cap material is an elastic, light, durable, biocompatible good conductor of electricity (biocompatibility means that it will not produce a strong galvanic effect with the skin and will not cause skin allergies). Conductive plastics, conductive rubbers, conductive foam materials, and elastic conductors with complex geometric shapes can all be used for the manufacture of electrode caps. Considering the ease of use, processing methods, cost and weight, the best known material is graphene conductive rubber.

[0043] The length of the electrode wire 213 is less than 3m, and the electrode wire 213 extends downward to the position of the bottom hem 13 of the vest, and the free end of the electrode wire 213 is electrically connected to the signal cable 16. The electrode wire 213 is used to connect the electrode stem 211 to the body surface potential mapping instrument, and its specific performance indicators should meet the relevant requirements of the instrument. Since the wires are numerous and long, their accumulated weight is considerable, so the cable material should be as thin and tough as possible. As another embodiment, it can also be connected to a wireless transmission module attached to the outer wall of the vest through an extremely short electrode wire 213.

[0044] In order to make the above-mentioned electrode wire 213 and the signal cable 16 connected thereto as regular as possible, a cable restraint belt 131 is provided on the outer surface of the vest hem 13. The cable restraint belt 131 includes a plurality of evenly arranged cable restraint circles 1311, and the signal cable 16 is arranged inside the cable restraint circle 1311.

[0045] In actual use, the lining member 14 is first put on the electrode stem neck 2112, and then the electrode cap 212 is put on the electrode stem head 2111. Due to the large number of electrodes, the lining member 14 can be prevented from falling off by squeezing the electrode cap 212. When cleaning, the electrode caps 212 are first removed one by one, and then the lining member 14 is removed. The lining member 14 and the electrode cap 212 can be sterilized at high temperature or chemically cleaned in different ways.

[0046] The vest device for measuring the electromotive force on the body surface proposed in the present invention comprises a vest body, a shoulder strap assembly for wearing and a center zipper portion are provided on the upper part of the vest body, an inner lining is sewn on the inner surface of the vest body, and the vest body comprises a plurality of vest units. Since an electrode member is provided in each vest unit, the electrode member comprises an electrode stem, an electrode cap provided at one end of the electrode stem, and an electrode wire provided at the other end of the electrode stem, in the actual measuring process, the electrode cap is in direct contact with the human skin, and the collected signal is transmitted to the sampling device through the signal wiring. In the present invention, since the vest device can be directly set on the human body in a wearable manner, and the electrode cap can be more closely fitted to various parts of the human skin through the shoulder strap assembly and the center zipper portion, the accuracy of the measuring signal is ensured. The vest device for measuring the electromotive force on the body surface proposed in the present invention is easy to wear, convenient for measuring the electromotive force on the human body surface, and meets the needs of practical applications.

[0047] Finally, it should be noted that the above-described embodiments are only specific implementations of the present invention, which are used to illustrate the technical solutions of the present invention, rather than to limit them. The protection scope of the present invention is not limited thereto.
