Description

Technical Field

[0001] The invention relates to the technical field of medical detection equipment, and in particular to an 18-lead elastic vest-type electrocardiogram acquisition device. Background Art

[0002] As a routine clinical examination item, electrocardiogram (ECG) testing is frequently used in outpatient diagnosis and treatment. Although compared with emergency scenarios, outpatient ECG examinations have relatively stable operating environments and loose lead connection time requirements, the problem of operational repeatability caused by the large daily number of patients is particularly prominent.

[0003] The current standard 12-lead system has significant structural defects: first, it cannot cover the right ventricle and left ventricular posterior wall area, and there are blind spots, which can easily lead to missed diagnosis of acute myocardial infarction of the right ventricle and left ventricular posterior wall; second, the discrete lead structure includes 6 chest leads and 4 limb leads, and each lead cable is independently wired and the interface is not interchangeable. It takes an average of 2-3 minutes to identify the line sequence and untangle before operation (according to clinical statistics, the operation error rate can reach 12-15%); third, the anatomical positioning accuracy requirements are strict, and the fourth rib on the right edge of the sternum must be met at the same time. The accuracy rate of novice operators is less than 60% due to positioning requirements such as the fourth intercostal space (V1) and the fourth intercostal space (V2) on the left edge of the sternum. Fourthly, the contact impedance stability defect. The signal distortion rate caused by the uneven contact pressure between the terminal electrode and the body surface is as high as 18%, which directly affects the interpretation of ST segment and T wave parameters. Fifthly, the equipment maintenance is time-consuming. The time for cable arrangement after a single examination accounts for about 25% of the total operation time. Sixthly, the traditional electrocardiogram examination requires both men and women to expose their chests and wipe the skin with alcohol or cold water, which leads to problems such as patient privacy exposure, alcohol allergy, and poor experience.

[0004] The above-mentioned technical pain points lead to a contradiction between operational efficiency and diagnostic accuracy in traditional electrocardiogram detection systems, and also give rise to secondary problems such as increased equipment depreciation rates. Therefore, the development of a new lead system with comprehensive coverage of the cardiac area, rapid deployment, fault-tolerant connection and easy maintenance has become a technical challenge that needs to be urgently solved in the field of medical equipment.

[0053] Directions:

[0054] The user first pulls open the fifth elastic Velcro male piece 14 and the fourth elastic Velcro female piece 15 by hand to separate the right edge of the left front piece 11 and the left edge of the right front piece 11 from each other, and then puts the elastic vest 1 on the body according to the normal dressing method so that the first sensor unit and the second sensor unit are respectively located on the back in front of the chest, and then fits the fifth elastic Velcro male piece 14 and the fourth elastic Velcro female piece 15 together according to the user's body shape to fix the right edge of the left front piece 11 and the left edge of the right front piece 11 to each other with a certain degree of tightness, and the bottom of the left edge of the left front piece 11 and the bottom of the right edge of the right front piece 11 and the bottom of the left and right edges of the back piece 12 will be automatically tightened with the help of multiple elastic bands 13, so that the end of each electrode column 22 is fitted on the user's skin.

[0055] In addition, the height of the first sensing unit and the second sensing unit can be adjusted according to the length of the user's upper body. When adjusting, the fourth elastic Velcro male piece 16 and the third elastic Velcro female piece 17 in each adjustment unit can be separated from each other by hand in turn, and then the height of the rear piece 12 and the two front pieces 11 can be moved up and down so that the first sensing unit and the second sensing unit are respectively located in front of and behind the user's heart, so that the end of each first electrode column 22 can accurately detect the heart rate data, and then the overlapping area of ​​the contact surface of the fourth elastic Velcro male piece 16 and the third elastic Velcro female piece 17 is adjusted to fit the fourth elastic Velcro male piece 16 and the third elastic Velcro female piece 17 in each adjustment unit together.

[0056] Next, the integrated plug 26 in the ECG collector 2 is plugged into the data interface of the ECG detector to achieve signal connection. After the ECG detector is started, each first electrode column 22 and each second electrode column 210 can transmit the user's heart rate data to the ECG detector and form an ECG (existing technology).

[0057] If the ECG detector is far away from the user, the end of the integrated plug 26 on the connecting line 213 can be pulled outward, so that the self-adhesive Velcro female strip 32 wrapped around the outside of the connecting line 213 is gradually separated from the first elastic Velcro male piece 31, so that the length of the connecting line 213 and the first elastic Velcro male piece 31 separated from each other is continuously increased, so that the integrated plug 26 can be connected to the data interface of the ECG detector, and the part of the connecting line 213 that is not separated from the first elastic Velcro male piece 31 is still fixed on the first elastic Velcro male piece 31; similarly, if the length of the connecting line 213 and the first elastic Velcro male piece 31 separated from each other is too long, the connecting line 213 can be coiled by hand and the coiled connecting line 213 can be pressed toward the direction of the first elastic Velcro male piece 31 to be fixed to the first elastic Velcro male piece 31 with the help of the self-adhesive Velcro female strip 32, so that it can be quickly and easily stored.

[0058] When all the connecting wires 213 leave the first elastic Velcro male piece 31, continuing to pull the connecting wires 213 with force may cause the connecting wires 213 to be pulled off the circuit board 21. However, the present invention also provides a wire clamp 33, and the connecting wires 213 are embedded between the arc-shaped side panel 3311 and a nearby arc-shaped corner edge 3321. The outer skin of the connecting wire 213 fits tightly with the arc-shaped side panel 3311, the inner wall and the arc-shaped corner edge 3321, and then the connecting wire 213 is clamped by pressure and friction. Even if the connecting wire 213 is pulled, the connecting wire 213 will not be separated from the circuit board 21. In addition, the baffle 3312 can also effectively prevent the connecting wire 213 from being separated from between the arc-shaped side panel 3311 and a nearby arc-shaped corner edge 3321 when being pulled forward.

[0059] If the first sensing unit in the ECG collector 2 fails or is damaged and cannot be used, the second elastic Velcro male sheet 24 can be torn open by hand, and then the first circuit board 21 can be pulled forward to make the end of each first electrode column 22 leave the elastic vest 1 and the first elastic Velcro female sheet 23, and then the end of the first multi-core data cable 25 can be unplugged from the first circuit board 21 with the help of the detachable connection of the first multi-core data cable 25; similarly, if the second sensing unit fails or is damaged and cannot be used, the second circuit board 29 can be removed in the same way; in this way, the disassembly of the first sensing unit and the second sensing unit is completed, and then the new first sensing unit or the second sensing unit can be installed back on the elastic vest 1 in the same way, and maintenance and replacement are simple and convenient.

[0060] In the initial state, the connecting line 213 is clamped in the line card 33, and one of the arc corner edges 3321 on the rotating plate 332 is embedded in the arc notch 3314. If the connecting line 213 needs to be replaced, the rotating plate 332 can be manually twisted to force the above-mentioned arc corner edge 3321 to come out of the arc notch 3314 and use the elasticity of the seat plate 331 itself to deform the arc side plate 3311 to the right to a certain extent. When the rotating plate 332 is rotated 90 degrees, the two arc corner edges 3321 are respectively distributed up and down, and the rotating plate 332 is located on the left side of the baffle 3312. Then, the connecting line 213 is pulled forward through the gap between the rotating plate 332 and the baffle 3312 to remove the connecting line 213 from the line card 33, and finally the connecting line 213 is pulled off the first elastic Velcro male piece 31.

[0061] In addition, when the previous user is wearing the vest, the innermost self-adhesive medical chest patch 5 in each self-adhesive medical chest patch combination and the innermost self-adhesive medical back patch 4 in the self-adhesive medical back patch combination are both adhered to the user's front chest and back skin. After the previous user finishes using and takes off the elastic vest 1, the next user can tear off the innermost self-adhesive medical chest patch 5 and the innermost self-adhesive medical back patch 4 in each self-adhesive medical chest patch combination in turn, and then wear the elastic vest 1 again, so as to avoid contact between the skin of the previous user and the skin of the next user, thereby preventing cross infection of bacteria, thereby achieving the reuse of the elastic vest 1 while ensuring that the hygiene level meets the standard.

[0062] 1. The present invention eliminates the need for operators to frequently distinguish leads and eliminate lead wire entanglement, thereby saving a lot of time and effectively improving work efficiency; at the same time, patients only need to wear it once to complete an 18-lead electrocardiogram, making up for the blind spot of a 12-lead electrocardiogram, thereby avoiding missed diagnosis of right ventricular and posterior wall myocardial infarction;

[0063] 2. The positions of each first electrode column 22 and each second electrode column 210 on the elastic vest 1 of the present invention are fixed, thereby avoiding the occurrence of operating errors and eliminating the need for operators to remember the position of each lead. It is more suitable for novices and has a lower operating threshold;

[0064] 3. The present invention can also automatically tighten the distance between the two front pieces 11 and the back piece 12 of the elastic vest 1 by means of each elastic band 13 on both sides, so that the end of each first electrode column 22 and each second electrode column 210 can always fit on the patient's skin, thereby ensuring that the examination process will not be interrupted or interfered with, thereby ensuring that the operator can correctly interpret the electrocardiogram to improve the examination accuracy;

[0065] 4. The present invention can also easily and quickly store the connecting wire 213, so that the end of the connecting wire 213 where the integrated plug 26 is located can be adjusted to a freely movable length as needed to adapt to different use distances of the electrocardiograph, thereby greatly facilitating use;

[0066] 5. The first sensor unit and the second sensor unit of the present invention both adopt a detachable structure. Once maintenance or replacement is required, the original first sensor unit or the second sensor unit can be simply and quickly removed and a new first sensor unit or the second sensor unit can be installed in the same way, thereby greatly facilitating maintenance or replacement and ensuring the continuous use of the equipment.

[0067] 6. The present invention avoids the step of wiping the skin with alcohol or cold water before electrocardiogram examination, and patients do not have to worry about the risk of exposing private parts such as the chest, as well as alcohol allergies, poor experience, and other problems; in addition, the two self-adhesive medical chest sticker combinations and the self-adhesive medical back sticker combination can prevent the skin of the previous user from contacting the skin of the next user, thereby preventing cross-infection of bacteria, thereby ensuring that the elastic vest 1 is reused to reduce the cost of use while ensuring that the hygiene level meets the standard.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
