Description

Technical Field

[0001] The present invention relates to the technical field of medical detection equipment, and particularly to a disposable chest-wrap type electrocardiogram acquisition device for clinical rescue. Background Art

[0002] Electrocardiogram is a technique for recording the electroactivity change graph generated by each cardiac cycle from the body surface through an electrocardiograph. In clinical rescue departments, bedside electrocardiogram has important diagnostic value and can quickly identify cardiac emergencies and provide guidance for rescue. However, there are many deficiencies in the lead system of traditional electrocardiogram, which affect its use efficiency and clinical effect.

[0003] The chest leads of traditional electrocardiogram consist of 6 chest lead wires, 3 to 4 limb lead wires and electrodes. Each lead wire needs to be connected strictly according to the specified position. This complex lead connection method brings the following problems in actual use:

[0004] Preparation stage: The operator needs to spend a lot of time differentiating the lead wires and solving the problem of lead wire entanglement. At the same time, it is necessary to accurately remember the positioning of each lead, and novices are prone to operation errors.

[0005] Operation stage: The electrodes fixed by suction cups are prone to falling off, resulting in interference of electrocardiogram signals and even inability to obtain interpretable electrocardiogram waveforms. For patients in rescue, such delays may directly affect the rescue effect and even cause fatal consequences. In addition, when the above problems occur, troubleshooting and reconnecting the leads still take a lot of time.

[0006] After the inspection: Medical staff need to re-organize the lead wires to avoid entanglement and damage, which further increases the work burden.

[0007] In addition, with the increase in the number of acute myocardial infarction cases, 18-lead electrocardiogram is usually required in the emergency rescue room to more comprehensively and quickly judge the condition and implement rescue. However, due to the cumbersome operation steps and time-consuming nature of traditional electrocardiogram, and the more complex operation of 18-lead electrocardiogram, most medical staff can only choose to check 12-lead electrocardiogram in actual work, which increases the risk of missed diagnosis.

[0008] In summary, the traditional electrocardiogram lead system has problems such as low efficiency and complex operation in the preparation, operation and organization stages, and it is difficult to meet the needs of clinical rescue. Therefore, there is an urgent need for a more efficient and convenient electrocardiogram lead system to improve the diagnostic efficiency and rescue success rate. Summary of the Invention

[0009] In view of the current situation of the above-mentioned existing technologies, the technical problem to be solved by the present invention is to provide a disposable chest-wrap type electrocardiogram acquisition device for clinical rescue, which greatly simplifies the operation, saves a large amount of time, significantly improves the work efficiency, is very convenient to use, reduces the operation difficulty and improves the operation accuracy to reduce the probability of missed diagnosis, wins precious rescue time and improves the rescue accuracy, and at the same time achieves both hygiene and cost reduction.

[0047] An inflation interface 5 internally communicated with the air storage bag 45 is also inserted on one side of the main airbag cloth 41.

[0048] An air flow network is formed among the air storage bag 45, the four columnar airbags 47, the two first air guide channels 46, the anti-loosening airbag package 48, the two second air guide channels 412 and the two strip-shaped airbags 410.

[0049] A magic tape male piece 6 and a magic tape female piece 7 that can be attached to each other are respectively fixed on the outer wall of one end and the inner wall of the other end of the medical elastic sealing cloth 1.

[0050] The medical elastic sealing cloth 1, the main airbag cloth 41, the first guiding airbag cloth 42, the side airbag cloth 43, the inner airbag cloth 44, the second guiding airbag cloth 411 and the side airbag strip 49 are all made of elastic materials with a sealing effect, such as medical PVC materials.

[0051] Usage method:

[0052] Medical staff first separate the two ends of the medical elastic sealing cloth 1 by hand, then lift the back of the first-aid patient upward by a certain distance or push the first-aid patient to lie on the side, then pass one end of the medical elastic sealing cloth 1 under the back or the pressed side of the first-aid patient, then wind the two ends of the medical elastic sealing cloth 1 around to the front of the first-aid patient's chest, and then adjust the vertical position and circumferential position of the medical elastic sealing cloth 1 so that each electrode post 22 in the electrode distributor 2 is located in front of the heart of the first-aid patient. Subsequently, the medical elastic sealing cloth 1 is fixed again. At this time, the air storage bag 45 is located on the back of the first-aid patient, and the two columnar airbags 47 on the left are respectively located on the front and back sides of the left waist of the patient, and the two columnar airbags 47 on the right are respectively located on the front and back sides of the right waist of the first-aid patient.

[0053] Before use, a certain amount of air is filled into the interior of the air storage bag 45 through the inflation interface 5, but the air flow network cannot be filled with air.

[0054] Next, lower the back of the first aid patient or lay the first aid patient lying on the side flat. The weight of the upper body of the first aid patient will press on the air storage bag 45. After the air storage bag 45 is pressed, the air inside it will be forced to flow outwards and enter the two first air guide channels 46 and the two second air guide channels 412 respectively. The excess air will continue to fill the four columnar air bags 47, the anti-loosening air bag package 48 and the two strip-shaped air bags 410. The two columnar air bags 47 on the left will flexibly clamp the left waist of the first aid patient, and the two columnar air bags 47 on the right will flexibly clamp the right waist of the first aid patient, so as to automatically prevent the circumferential displacement of the medical elastic sealing cloth 1; after the anti-loosening air bag package 48 is filled, it will press the connecting plate 21 against the inner wall of the limiting piece 3, so that each electrode post 22 extends outwards to the greatest extent to ensure that the end of each electrode post 22 is attached to the skin of the first aid patient, thus ensuring the stability and firmness of data collection; after the two strip-shaped air bags 410 are filled, they will both flexibly hold the skin of the first aid patient's chest and the part of the back that is not in contact with the bed surface, and then prevent the up and down displacement of the medical elastic sealing cloth 1 by means of friction, so as to further ensure that the ends of the electrode posts 22 will not shift.

[0055] After the inspection is completed, as long as the two ends of the medical elastic sealing cloth 1 are separated again, and then the back of the first aid patient is lifted upwards by a certain distance or the first aid patient is pushed to lie on the side again, in this way, the pressure received by the air storage bag 45 will disappear immediately. Part of the air in the four columnar air bags 47, the anti-loosening air bag package 48 and the two strip-shaped air bags 410 will separate into the air storage bag 45. The four columnar air bags 47, the anti-loosening air bag package 48 and the two strip-shaped air bags 410 will all loosen to a certain extent and will not affect wearing and taking off. Finally, the medical elastic sealing cloth 1 is pulled outwards, and then the connecting plate 21 together with each electrode post 22 can be taken out through the opening 31 for repeated use, and the remaining medical elastic sealing cloth 1 can be discarded. Subsequently, personnel can be arranged to install the connecting plate 21 together with each electrode post 22 back onto a new medical elastic sealing cloth 1, which not only ensures hygiene but also reduces the use cost.

[0056] Next, insert the integrated plug 24 in the electrocardiogram collector 2 into the data interface of the electrocardiogram detector to achieve signal connection. After starting the electrocardiogram detector, each electrode post 22 can transmit the heart rate data of the user to the inside of the electrocardiogram detector and form an electrocardiogram (prior art).

[0057] 1. In the present invention, the originally loose electrode columns 22 are integrated onto the connecting plate 21, and the connecting plate 21 is fixed to the medical elastic sealing cloth 1 with a chest-wrap structure, eliminating the process of frequently differentiating leads and eliminating the entanglement of lead wires. Thus, the operation is greatly simplified, saving a large amount of time and significantly improving work efficiency. At the same time, it is greatly convenient for use;

[0058] 2. In the present invention, the distribution positions of each electrode column 22 are fixed, and the positioning of each electrode column 22 can be automatically completed with just one wearing. Thus, the operation difficulty is reduced, eliminating the need for medical staff to memorize the position of each lead, and it is more suitable for novices; also, the operation accuracy is improved, and even the more complex 18-lead electrocardiogram can be easily solved. Therefore, it is beneficial for the rescue of patients with acute myocardial infarction and reduces the probability of missed diagnosis;

[0059] 3. In the present invention, with the aid of the automatic positioning mechanism 4 and using the weight of the first-aid patient himself, the four columnar airbags 47, the anti-loosening airbag package 48, and the two strip-shaped airbags 410 can be filled. Thus, the medical elastic sealing cloth 1 after wearing will not shift up and down or circumferentially, and at the same time, it effectively prevents the connecting plate 21 from loosening, enabling the end of each electrode column 22 to always fit against the skin of the first-aid patient. Therefore, it ensures that the inspection process will not be interrupted or interfered with, ensuring that medical staff can always correctly interpret the electrocardiogram, thus winning precious rescue time and improving the rescue accuracy;

[0060] 4. The electrocardiogram collector 2 of the present invention adopts a detachable structure. After the medical elastic sealing cloth 1 is used up, the connecting plate 21 together with each electrode column 22 can be taken out through the opening 31 for reuse, and the remaining medical elastic sealing cloth 1 can be discarded. Subsequently, personnel can be arranged to install the connecting plate 21 together with each electrode column 22 onto a new medical elastic sealing cloth 1. This not only ensures hygiene but also reduces the use cost.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
