Description

Technical Field

[0001] The invention relates to the technical field of seamless underwear, in particular to a seamless tight underwear with electrocardiogram data leads and a knitting method thereof. Background Art

[0002] Cardiovascular disease has become a major disease that endangers human health, and electrocardiogram is the main basis for treating such diseases. Conventional electrocardiogram obtains a small amount of information about the heart state in a limited time, so the collected data has a large blind spot. Therefore, it is necessary to monitor the patient for a long time in real time through the corresponding monitoring device and record the patient's electrocardiogram data. The advent of the 24-hour dynamic electrocardiogram monitor fills this gap, but the arrangement of the instrument, lead electrodes and lead wires on the body is very inconvenient, affecting the patient's normal daily activities.

[0003] Patent ZL202220562862.3 records that the utility model discloses an ECG lead smart underwear, including a clothing body, wherein the clothing body is inlaid with metal conductive buttons inside and outside the fabric at the locations where the medical standard ECG electrodes are set, a female buckle of the conductive button is provided on the inside of the underwear, a male buckle of the conductive button is provided on the outside of the underwear, a fixing spring is provided in the female buckle, the female buckle and the male buckle are fixedly connected by the fixing spring, the female buckle of the metal button is connected to the electrode sheet, and the female buckle of the metal button is connected to the processor through a lead wire.

[0004] The core of this patented technology is to provide a general direction for ECG data collection, integrating a bunch of devices such as redundant instruments, lead electrodes and lead wires into a piece of underwear. As long as the human body wears this smart underwear, the ECG data can be collected and sent to the smart terminal for presentation, which solves the wearing problem very conveniently.

[0005] But it is not perfect enough. As we all know, human ECG is a microcurrent, which is a low-frequency signal. The lead electrode can basically not detect the signal when it is a small distance away from the human body surface. The lead electrode of the above patent uses metal mother-and-child buckles. First of all, not to mention that the contact with the human body surface is very disgusting and uncomfortable to wear, the most important thing is that in addition to the unstable and unreliable contact point, the contact point is too narrow and easy to deviate from the human ECG medical standard monitoring position; secondly, the lead wire is directly used as yarn to weave underwear in its forming part, which is directly in contact with the human body surface. In the process of transmitting signals, it carries myoelectric interference and respiratory interference, etc.; all of which are hidden dangers that can easily cause inaccurate data collection. In addition, the production of such smart underwear is inconvenient, and requires multiple subsequent processes to be added, with low production efficiency and poor economic benefits. Summary of the invention

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

[0007] Another object of the present invention is to overcome the above defects of the prior art and provide a weaving method for seamless tights for ECG data leads that has integrated weft knitting, reduces subsequent processes, improves production efficiency, and improves data transmission performance.

[0008] In order to achieve the above purpose, the present invention is realized by the following technical scheme: a seamless tight underwear with ECG data leads, comprising a tight underwear, characterized in that a plurality of lead input electrodes corresponding to the standard monitoring positions of human ECG medicine are woven integrally on the inner surface of the tight underwear, and the same number of lead output electrodes as the lead electrodes are woven integrally on the outer surface of the tight underwear, the lead output electrodes are paired with the lead input electrodes one-to-one and connected through a lead wire, wherein the lead wire is woven integrally on the outer surface of the tight underwear, the lead output electrodes are gathered in an interconnection area at the same position on the tight underwear, but the lead output electrodes exist independently of each other, and an ECG chip processor is placed on the interconnection area; The bodysuit is a seamless knitted one-piece garment consisting of an inner surface of a fabric woven by warp and weft knitting of an inner yarn and an outer surface of a fabric woven by warp and weft knitting of an outer yarn, wherein the inner yarn and the outer yarn are both non-conductive yarns, the lead input electrode is a jacquard structure woven by weft knitting of conductive yarn on the outside of the inner yarn, and the lead output electrode and the lead wire belt are jacquard structures woven by weft knitting of conductive yarn on the outside of the outer yarn.

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

[0010] The tight underwear of the present invention adopts seamless weft knitting technology and has great shrinkage, which can ensure the reliability of zero contact between the lead input electrode and the human body surface at all times. In addition, the lead output electrode and the lead wire are on the outer surface of the tight underwear and do not contact the human body surface. They only play the role of data transmission, avoiding interference with collected data and improving the accuracy of collected data.

[0011] The tight underwear of the present invention is convenient to wear, and can expand the application field of electrocardiogram monitoring, such as in the military field, real-time status monitoring of soldiers' physical conditions on the battlefield, which is convenient for the command center to make the right choice; for example, in the sports field, like marathon running, more and more people are participating, and athletes wearing such clothing can greatly reduce the probability of sports safety accidents, etc.

[0012] Preferably, each of the lead input electrodes, lead output electrodes and lead wire strips is woven from a single continuous yarn from beginning to end.

[0013] The working process of conventional circular knitting machines is a weft knitting forward rotation and looping weaving method. When it comes to the lead input electrode, lead output electrode and lead wire belt, the conventional method is to control the knitting needle to hook the conductive yarn to participate in weaving. When the weft direction reaches the corresponding jacquard structure data width, the knitting needle no longer hooks the conductive yarn and cuts the yarn in time. In this way, each rotation of the circular knitting machine forms a small section of conductor yarn that is radially stacked to form a jacquard structure pattern, that is, the lead input electrode, lead output electrode and lead wire belt. This is a conventional method. They are formed by countless small wire segments being connected side by side, which can also achieve weaving, and there is no need to change the working mode of the circular knitting machine. However, the present invention does not adopt this method. The reason is that the resistance of the lead wire belt and the like formed by countless small wire segments being connected side by side is relatively large, which is not conducive to the transmission of ECG micro-signals. Therefore, the lead wire belt and the like need to be woven from beginning to end with a single continuous yarn, so it can only be achieved by using a special and uncommon weaving method such as weft knitting forward and reverse reciprocating weaving.

[0014] Preferably, the lead input electrode and the lead output electrode are in a square jacquard pattern, and the lead wire tape is in a long and thin strip jacquard pattern.

[0015] Preferably, the conductive yarn is a silver fiber yarn. The conductive yarn is not limited to silver fiber yarn, but can also be other metal fiber yarns with better conductive properties.

[0016] Preferably, each of the lead input electrodes protrudes from the inner surface of the tight underwear and forms a step therewith. The step between the lead input electrode and the tight underwear allows the lead input electrode to be pressed by the tight underwear and closely attached to the human body surface, thereby improving the accuracy of monitoring data.

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

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

[0019] As an alternative to the above solution, the electric chip processor is provided with a plurality of metal conductive electrode clamps which are connected to its internal circuit through wires and the number of which is the same as the lead output electrodes.

[0020] A method for knitting a seamless tights for ECG data leads, characterized in that the tights are knitted in one piece using a computer jacquard circular knitting machine, and a conventional weft knitting forward and circular knitting method is used when knitting a tights sub-body that does not involve three parts, namely, lead input electrodes, lead output electrodes, and lead wires, but a special weft knitting forward and reverse reciprocating knitting method is used when knitting a tights main body that involves three parts, namely, lead input electrodes, lead output electrodes, and lead wires.

[0021] The working process of conventional circular knitting machines is a weft knitting forward rotation and looping weaving method. When it comes to the lead input electrode, lead output electrode and lead wire belt, the conventional method is to control the knitting needle to hook the conductive yarn to participate in weaving. When the weft direction reaches the corresponding jacquard structure data width, the knitting needle no longer hooks the conductive yarn and cuts the yarn in time. In this way, each rotation of the circular knitting machine forms a small section of conductor yarn that is radially stacked to form a jacquard structure pattern, that is, the lead input electrode, lead output electrode and lead wire belt. This is a conventional method. They are formed by countless small wire segments being connected side by side, which can also achieve weaving, and there is no need to change the working mode of the circular knitting machine. However, the present invention does not adopt this method. The reason is that the resistance of the lead wire belt and the like formed by countless small wire segments being connected side by side is relatively large, which is not conducive to the transmission of ECG micro-signals. Therefore, the lead wire belt and the like need to be woven from beginning to end with a single continuous yarn, so it can only be achieved by using a special and uncommon weaving method such as weft knitting forward and reverse reciprocating weaving.

[0022] In this way, the lead input electrode, the lead output electrode and the lead wire are woven from a single continuous yarn from beginning to end using a weft knitting forward and reverse reciprocating weaving method, thereby reducing resistivity and improving data transmission performance.

[0023] Beneficial effects: The lead input electrode, lead output electrode and lead wire of the present invention are all formed by an integrated seamless weft knitting process during the weaving process of the tight underwear, which actually forms a jacquard structure on the tight underwear, without any sense of disobedience, thus solving the problem of wearing comfort. The tight underwear has a large shrinkage capacity, which can ensure the reliability of the lead input electrode and the human body surface at all times. In addition, the lead output electrode and the lead wire are on the outer surface of the tight underwear and do not contact the human body surface. They only play a role in data transmission, avoiding interference with collected data and improving the accuracy of collected data. The lead input electrode, lead output electrode and lead wire are woven from a single continuous yarn from beginning to end using a weft knitting forward and reverse reciprocating weaving method, which reduces resistivity and improves data transmission performance.

[0028] 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 which are connected to its internal circuit and the same number as the lead output electrodes 4. The metal conductive male buckle 5 and the metal conductive female buckle 6 can be separably paired and engaged one by one.

[0029] like Figure 4 and Figure 5As shown, the tight underwear 1 is a seamless knitted one-piece garment composed of an inner surface of a fabric knitted by a lining yarn 8 and an outer surface of a fabric knitted by a surface yarn 9, wherein the lining yarn 8 and the surface yarn 9 are both non-conductive yarns, the lead input electrode 2 is a jacquard structure knitted by a conductive yarn 10 on the outside of the lining yarn 8, and the lead output electrode 4 and the lead wire band 3 are jacquard structures knitted by a conductive yarn 10 on the outside of the surface yarn 9. The conductive yarn 10 is a silver fiber yarn.

[0030] Each lead input electrode 2, lead output electrode 4 and lead wire band 3 are woven from a single continuous yarn from beginning to end. The lead input electrode 2 and the lead output electrode 4 are square jacquard patterns, and the lead wire band 3 is a thin and long jacquard pattern. Each lead input electrode 2 protrudes from the inner surface of the tight underwear 1 and forms a step therewith.

[0031] Embodiment 2: Six lead input electrodes 2 corresponding to the standard medical monitoring positions of human electrocardiogram are woven integrally on the inner surface of the tight underwear 1, and the same number of lead output electrodes 4 as the lead electrodes are woven integrally on the outer surface of the tight underwear 1. The lead output electrodes 4 are paired one-to-one with the lead input electrodes 2 and are connected via a lead wire strap 3.

[0032] The outer surface of each lead output electrode 4 is coated with a metal conductive layer. The electric chip processor 7 is provided with six attached electrode sheets connected to its internal circuit through wires and the same number as the lead output electrodes 4. The attached electrode sheets are made of plastic film or foam discs coated with adhesive.

[0033] The rest is the same as in Example 1.

[0034] Embodiment 3: Eight lead input electrodes 2 corresponding to the standard medical monitoring positions of human electrocardiogram are woven integrally on the inner surface of the tight underwear 1, and the same number of lead output electrodes 4 as the lead electrodes are woven integrally on the outer surface of the tight underwear 1. The lead output electrodes 4 are paired one-to-one with the lead input electrodes 2 and are connected via a lead wire strap 3.

[0035] The electric chip processor 7 is provided with eight metal conductive electrode clamps which are connected to its internal circuit through wires and the number of which is the same as the lead output electrodes 4 .

[0036] The rest is the same as in Example 1.

[0037] Knitting method: A knitting method for a seamless tight underwear with ECG data leads, wherein the tight underwear 1 is knitted integrally with a computer jacquard circular knitting machine, and a conventional weft knitting forward and circular knitting method is used when knitting a tight underwear sub-body that does not involve the lead input electrode 2, the lead output electrode 4 and the lead wire band 3. However, a special weft knitting forward and reverse reciprocating knitting method is used when knitting a tight underwear main body that involves the lead input electrode 2, the lead output electrode 4 and the lead wire band 3. That is, in the corresponding section, a computer controls an electromagnetic needle selector to allow the knitting needle to hook into the conductive yarn, wherein the conductive yarn 10 is knitted outside the inner yarn 8 when the lead input electrode 2 is knitted (see Figure 4 ), the conductive yarn 10 is woven outside the surface yarn 9 when the lead output electrode 4 and the lead wire band 3 (see Figure 5 ), the conductive yarn 10 is reciprocating and winding along the width of the latitude direction in the weft knitting forward and reverse reciprocating weaving mode, that is, the two ends of the conductive yarn 10 are not broken and continuously go down, similar to drawing a continuous winding line from top to bottom, and the continuous back and forth weaving is formed. Of course, at this time, the lining yarn 8 and the surface yarn 9 of the tights are also knitted forward and reversely at the same time, because the general computer jacquard knitting circular machine has four lines in the process of 360-degree rotation, each responsible for weaving a 90-degree area, and each area is then connected in sequence.

[0038] Therefore, the present invention adopts a weaving method that combines a weft knitting forward rotation and looping weaving method with a weft knitting forward and reverse reciprocating weaving method to complete the process.
