Description

Technical Field

[0001] This utility model relates to the field of seamless underwear technology, and more specifically to a seamless tight-fitting underwear with electrocardiogram data leads. Background Technology

[0002] Cardiovascular disease has become a major threat to human health, and electrocardiogram (ECG) is the primary basis for its treatment. However, a standard ECG only acquires a limited amount of information about the heart's condition within a limited timeframe, resulting in significant data blind spots. Therefore, it is necessary to use appropriate monitoring devices for long-term, real-time monitoring of patients and to record their ECG data. The advent of 24-hour Holter monitoring has filled this gap; however, the instrument, leads, and wires are very inconvenient to have on the body, affecting patients' normal daily activities.

[0003] Patent ZL202220562862.3 discloses a smart underwear with ECG leads, comprising a garment body. The garment body has metal conductive buttons embedded on the inner and outer sides of the fabric at the locations where medical standard ECG electrodes are set. The inner side of the underwear has a female button with conductive buttons, and the outer side of the underwear has a male button with conductive buttons. The female button has a fixing spring, and the female and male buttons are fixedly connected by the fixing spring. The female button is connected to the electrode plate, and the female button is connected to the processor through a lead wire.

[0004] The core of this patented technology is to provide a general direction for electrocardiogram (ECG) data acquisition, integrating a bunch of devices such as cumbersome instruments, leads, and leads into a single piece of underwear. As long as the human body wears this smart underwear, ECG data can be collected and transmitted to a smart terminal for presentation, which solves the wearable problem very conveniently.

[0005] However, it's not perfect. As we all know, human electrocardiograms (ECGs) are microcurrents, belonging to low-frequency signals. When the lead electrodes are only a small distance from the body surface, the signal is practically undetectable. The patented lead electrodes use metal snap fasteners, which, firstly, are uncomfortable to wear and feel uncomfortable against the skin. More importantly, besides being unstable and unreliable, the contact points are too narrow and easily deviate from the standard medical monitoring position for human ECGs. Secondly, the lead wires are woven directly into the underwear as yarn, directly contacting the body surface. During signal transmission, they are susceptible to interference from electromyography (EMG) and respiration, all of which can easily lead to inaccurate data collection. Furthermore, the production of this type of smart underwear is inconvenient, requiring multiple subsequent processes, resulting in low production efficiency and poor economic benefits. Utility Model Content

[0006] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a seamless tight-fitting underwear for ECG data leads that is comfortable to wear, avoids interference with data collection, improves the accuracy of data collection, and expands the application field of ECG monitoring.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a seamless tight-fitting underwear for electrocardiogram (ECG) data leads, comprising a tight-fitting underwear, characterized in that a plurality of lead input electrodes corresponding to the standard monitoring positions of human ECG are integrally woven on the inner surface of the tight-fitting underwear, and a number of lead output electrodes of the same number as the lead electrodes are integrally woven on the outer surface of the tight-fitting underwear, wherein the lead output electrodes are paired one-to-one with the lead input electrodes and connected by a lead wire, wherein the lead wire is integrally woven on the outer surface of the tight-fitting underwear, and these lead output electrodes are clustered in an interconnected area at the same position on the tight-fitting underwear, but these lead output electrodes exist independently of each other, and an ECG chip processor is disposed on the interconnected area;

[0008] The shapewear is a seamless knitted garment consisting of an inner surface of fabric woven from lining yarn and an outer surface of fabric woven from outer yarn. Both the lining and outer yarns are non-conductive. The input electrode is a jacquard structure woven from conductive yarns on the outside of the lining yarn. The output electrode and the lead wire are jacquard structures woven from conductive yarns on the outside of the outer yarn.

[0009] The input electrode, output electrode, and lead wire of this invention are all integrally weft-knitted during the weaving process of the tight-fitting underwear, forming a jacquard structure on the tight-fitting underwear without any sense of incongruity, thus solving the problem of wearing comfort.

[0010] This utility model of compression underwear uses a seamless weft knitting process, which has great shrinkage and can ensure that the input electrode of the lead is in constant zero contact with the human body surface. In addition, the output electrode and lead wire are on the outer surface of the compression underwear and do not come into contact with the human body surface. They only serve the purpose of data transmission, avoiding interference with the collected data and improving the accuracy of the collected data.

[0011] This utility model of compression underwear offers convenient wear and expands the application fields of electrocardiogram monitoring, such as in the military field, to monitor the real-time physical condition of soldiers on the battlefield, facilitating correct choices by the command; in the sports field, such as marathons, where more and more participants are wearing this type of clothing, which can greatly reduce the probability of sports safety accidents, etc.

[0012] Preferably, each of the lead input electrode, lead output electrode, and lead cable is woven from a single continuous yarn from start to finish.

[0013] Conventional circular knitting machines operate using a weft-knitting forward-rotating loop knitting method. When it comes to the input electrodes, output electrodes, and lead wires, the conventional approach is for the computer-controlled needles to hook into the conductive yarns to participate in the knitting. When the weft reaches the corresponding jacquard fabric width, the needles stop hooking into the conductive yarns and cut the yarns at the appropriate time. In this way, each rotation of the circular knitting machine forms small segments of conductive yarns that are radially stacked to form the jacquard fabric pattern, which represents the input electrodes, output electrodes, and lead wires. This is the conventional method, where they are formed by countless small yarn segments side by side, which can also achieve the knitting without changing the working mode of the circular knitting machine. However, this invention does not adopt this method because the resistance of the lead wires formed by countless small yarn segments side by side is relatively high, which is not conducive to the transmission of ECG micro signals. Therefore, the lead wires need to be knitted from a single continuous yarn from beginning to end, which can only be achieved by using the special and uncommon weft-knitting forward-reverse reciprocating knitting method.

[0014] Preferably, the input and output electrodes are square jacquard patterns, and the lead wires are long and thin jacquard patterns.

[0015] Preferably, the conductive yarn is silver fiber yarn. However, the conductive yarn is not limited to silver fiber yarn; it can also be other metal fiber yarns with superior conductivity.

[0016] Preferably, each of the input electrodes protrudes from the inner surface of the compression garment, creating a height difference. This height difference between the input electrodes and the compression garment allows them to be pressed tightly against the body surface, thereby improving the accuracy of the monitoring data.

[0017] Preferably, each of the lead output electrodes is sewn with a metal conductive male buckle, and the ECG chip processor is provided with a number of metal conductive female buckles that are connected to its internal circuit and are the same number as the lead output electrodes. The metal conductive male buckles and the metal conductive female buckles can be separably paired and engaged one-to-one.

[0018] As an alternative to the above scheme, a metal conductive layer formed by the method is coated on the outer surface of each of the lead output electrodes. The electronic chip processor is provided with a number of attached electrode sheets that are connected to its internal circuit through wires and have the same number as the lead output electrodes. The attached electrode sheets are made of plastic film or foam disk coated with adhesive.

[0019] As an alternative to the above solution, the electrical chip processor is provided with several metal conductive electrode clips that are connected to its internal circuitry by wires and whose number is the same as that of the leaded output electrodes.

[0020] Beneficial effects: The input electrode, output electrode, and lead wire of this invention are all integrally formed using a seamless weft knitting process during the weaving of the shapewear, effectively creating a jacquard structure on the shapewear without any awkwardness, thus solving the problem of wearing comfort. The shapewear has significant elasticity, ensuring reliable zero-contact between the input electrode and the body surface at all times. Furthermore, the output electrode and lead wire are located on the outer surface of the shapewear, not in contact with the body surface, serving only a data transmission function, thus avoiding data interference and improving the accuracy of the collected data.

[0027] To make the technical means, creative features and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.

[0028] Example 1: As Figure 1 As shown, a seamless tight-fitting underwear for ECG data leads includes a tight-fitting underwear 1. Four lead input electrodes 2 corresponding to the standard ECG medical monitoring positions are integrally woven on the inner surface of the tight-fitting underwear 1. The number of lead output electrodes 4, the same as the number of lead electrodes, are integrally woven on the outer surface of the tight-fitting underwear 1. The lead output electrodes 4 are paired one-to-one with the lead input electrodes 2 and connected by a lead wire strip 3. The lead wire strip 3 is integrally woven on the outer surface of the tight-fitting underwear 1. These lead output electrodes 4 are clustered in an interconnected area at the same location on the tight-fitting underwear 1, but these lead output electrodes 4 exist independently of each other. An ECG chip processor 7 (commercially available) is placed on the interconnected area.

[0029] like Figure 2 and Figure 3 As shown, each lead output electrode 4 is sewn with a metal conductive male buckle 5, and the ECG chip processor 7 is provided with four metal conductive female buckles 6 that are connected to its internal circuit and are the same number as the lead output electrodes 4. The metal conductive male buckles 5 and the metal conductive female buckles 6 can be separable and paired one-to-one.

[0030] like Figure 4 and Figure 5 As shown, the tight-fitting underwear 1 is a seamless knitted garment consisting of an inner surface of fabric woven from lining yarn 8 and an outer surface of fabric woven from outer yarn 9. Both lining yarn 8 and outer yarn 9 are non-conductive yarns. The input electrode 2 is a jacquard structure woven from conductive yarn 10 on the outside of the lining yarn 8. The output electrode 4 and the connecting strip 3 are also jacquard structures woven from conductive yarn 10 on the outside of the outer yarn 9. The conductive yarn 10 is silver fiber yarn.

[0031] Each input electrode 2, output electrode 4, and lead wire 3 is woven from a single continuous yarn from start to finish. The input electrode 2 and output electrode 4 have a square jacquard pattern, while the lead wire 3 has a thin strip jacquard pattern. Each input electrode 2 protrudes from the inner surface of the bodysuit 1, creating a height difference between them.

[0032] Example 2: The inner surface of the tight-fitting underwear 1 is integrally woven with six lead input electrodes 2 corresponding to the standard monitoring positions of human electrocardiogram. The outer surface of the tight-fitting underwear 1 is integrally woven with the same number of lead output electrodes 4 as the lead electrodes. The lead output electrodes 4 are paired one-to-one with the lead input electrodes 2 and connected by a lead wire 3.

[0033] Each lead output electrode 4 has a metal conductive layer formed by a method coated on its outer surface. The electronic chip processor 7 is provided with six attached electrode sheets that are connected to its internal circuit through wires and have the same number as the lead output electrodes 4. The attached electrode sheets are made of plastic film or foam disc coated with adhesive.

[0034] The rest is the same as in Example 1.

[0035] Example 3: The inner surface of the tight-fitting underwear 1 is integrally woven with eight lead input electrodes 2 corresponding to the standard monitoring positions of human electrocardiogram. The outer surface of the tight-fitting underwear 1 is integrally woven with the same number of lead output electrodes 4 as the lead electrodes. The lead output electrodes 4 are paired one-to-one with the lead input electrodes 2 and connected by a lead wire 3.

[0036] The electronic chip processor 7 is equipped with eight metal conductive electrode clips that are connected to its internal circuitry via wires, and the number of these clips is the same as that of the lead output electrodes 4.

[0037] The rest is the same as in Example 1.

[0038] Knitting Method: A knitting method for a seamless compression underwear with ECG data leads. The compression underwear 1 is knitted in one piece using a computerized jacquard circular knitting machine. When knitting the sub-body of the compression underwear that does not involve the three parts of the lead input electrode 2, lead output electrode 4, and lead wire 3, a conventional weft knitting forward and reverse circular knitting method is used. However, when knitting the main body of the compression underwear that involves the three parts of the lead input electrode 2, lead output electrode 4, and lead wire 3, a special weft knitting forward and reverse reciprocating knitting method is used. That is, in the corresponding sections, the computer-controlled electromagnetic needle selector allows the knitting needle to hook into the conductive yarn. Specifically, when knitting the lead input electrode 2, the conductive yarn 10 is knitted outside the lining yarn 8 (see...). Figure 4 When the lead output electrode 4 and the lead wire 3 are connected, the conductive yarn 10 is woven outside the outer yarn 9 (see...). Figure 5 The conductive yarn 10 moves back and forth along the width of the weft direction in the forward and reverse reciprocating knitting method. That is, the two ends of the conductive yarn 10 are not broken and continue downward, similar to drawing a continuous meandering line from top to bottom, and continuously knitting back and forth to form the shape. Of course, at this time, the inner yarn 8 and outer yarn 9 of the tight underwear are also knitted in forward and reverse directions at the same time. This is because a typical computer jacquard circular knitting machine has four incoming yarns during the 360-degree rotation, each responsible for knitting a 90-degree area, and the areas are then connected sequentially.

[0039] Therefore, this utility model adopts a weft knitting method that combines forward and reverse circular knitting with forward and reverse reciprocating knitting.
