The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0017] like Figures 1-3 As shown in the figure, this application embodiment proposes an EIT electrode binding strap, including: an elastic fabric substrate 1, which can be stretched and whose two ends can be quickly connected and disconnected; a plurality of microfiber electrodes 2, which are spaced apart on the fabric substrate 1; a wire 3, which is disposed inside the fabric substrate 1 and electrically connected to the microfiber electrodes 2; a first wiring strip 4, which is connected to one end of the fabric substrate 1; and a second wiring strip 5, which is connected to the other end of the fabric substrate 1; and both the first wiring strip 4 and the second wiring strip 5 are provided with cables (not shown in the figure), the first ends of the two cables are electrically connected to the two ends of the wire 3, and the second ends of the two cables can be configured to connect to a power source.
[0018] Based on the above technical solution, this application can be applied to the visualization and continuous dynamic monitoring of the lungs. The fabric substrate 1 can be stretched, and its two ends joined together to bind it to the patient's body, with the microfiber electrode 2 in close contact with the patient's skin. Cables on the first and second wiring straps 4 are connected to a power source, and current flows between the cable, wire 3, microfiber electrode 2, and the wire. The microfiber electrode 2 is energized and can apply a weak current to the patient's body to sense changes in thoracic bioelectrical impedance during respiration, and to monitor the permeability of different lung regions using corresponding imaging algorithms. The system displays the patient's airway function status, providing real-time dynamic lung tomography ventilation images. Furthermore, the microfiber electrode 2 and the elastic fabric substrate 1 are inexpensive, saving significant costs compared to the metal electrodes and conductive silicone used in existing EIT electrode bandages. This facilitates the use of this EIT electrode bandage as a disposable consumable, eliminating hygiene concerns and preventing cross-infection. The lightweight nature of the microfiber electrode 2 and the elastic fabric substrate 1 also makes this EIT electrode bandage lighter, causing minimal discomfort when worn on the patient and facilitating operation by medical staff.
[0019] Nowadays, people are paying more and more attention to lung examinations. Lung testing can help detect lung diseases early, including lung cancer, lung infections, and pulmonary fibrosis. Especially for potentially fatal diseases like lung cancer, early detection can provide better treatment opportunities and increase the possibility of a cure. For patients already diagnosed with lung disease, lung testing can help doctors monitor the progression and recurrence of the disease. Regular lung testing can detect changes in the disease in a timely manner, helping to adjust treatment plans and provide better treatment outcomes. At the same time, lung testing is also suitable for some high-risk groups, such as smokers and people with a family history of lung disease. This EIT electrode strap can assist in lung testing, helping to screen for potential problems and take corresponding preventive measures to reduce the risk of disease progression.
[0020] In practical applications, the fabric substrate 1 is tied to the patient's chest, and the microfiber electrode 2 on the fabric substrate 1 is in close contact with the patient's skin. The cables inside the first wiring strip 4 and the second wiring strip 5 are energized, so that the microfiber electrode 2 is energized. The microfiber electrode 2 can apply a weak current to the patient's chest, which makes it easy to sense the changes in the bioelectrical impedance of the chest cavity during the patient's breathing. At this time, the ventilation function status in different areas of the lung can be monitored using the corresponding imaging algorithm to present real-time dynamic lung tomographic ventilation images.
[0021] To prevent hygiene problems and avoid cross-infection, the EIT electrode strap of this application is inexpensive and can be used as a disposable consumable.
[0022] In order to ensure a good connection between the microfiber electrode 2 and the wire 3, the EIT electrode binding tape of this application also includes a number of conductive elements 6 corresponding to the microfiber electrode 2. The conductive elements 6 are spaced apart on the fabric substrate 1 and electrically connected to the wire 3. The microfiber electrode 2 is connected to the conductive element 6 one by one.
[0023] The microfiber electrode 2 is detachably connected to the conductive component 6, which reduces the difficulty of the process and saves costs. Specifically, the microfiber electrode 2 is bonded to the conductive component 6, or the conductive component 6 includes a metal buckle, and the microfiber electrode 2 is snapped onto the conductive component 6. Alternatively, other common detachable connection methods in the prior art can be used, which will not be described in detail here.
[0024] Furthermore, in order to reduce costs and process difficulty, while ensuring good connection between the conductive component 6, the wire 3, and the microfiber electrode 2, this application uses a metal buckle as the conductive component 6 and presses the metal buckle onto the fabric substrate 1.
[0025] To ensure the correct use of the electrode straps and prevent unauthorized theft or alteration of user data, thereby protecting patient privacy and health information, an encryption module 11 is installed on the straps. This module contains a built-in encryption chip and can be connected to the host computer via a cable. Subsequent testing is only performed after the host computer recognizes the encryption module 11.
[0026] In some embodiments, the microfiber electrode 2 includes a conductive fabric and a conductive PU component. The conductive fabric and conductive PU component in this application can be selected from common structures in the prior art, and their detailed structures will not be described here.
[0027] The fabric substrate 1 of this application needs to be tied to the patient's body, specifically to the patient's chest. Different patients have different body shapes. Therefore, in order to adapt to patients of various body shapes, the fabric substrate 1 can be woven into an elastic fabric using a weaving technique commonly used in the prior art. In order to prevent the signal line inside the fabric substrate 1 from being broken, an elastic buffer rope 7 is also provided inside the fabric substrate 1. This rope can be used to buffer when the fabric substrate 1 is stretched, ensuring that the signal line will not be broken and that the microfiber electrode 2 can stably output current for lung monitoring.
[0028] The two ends of the fabric substrate 1 are connected by Velcro, buttons, snaps, or zippers. This allows the fabric substrate 1 to be quickly tied to the patient's body, so that the microfiber electrode 2 can be closely attached to the patient's skin, and the fabric substrate 1 can be quickly removed from the patient's body after the test.
[0029] This EIT electrode strap also includes a main wiring strap 8, which has a first wiring terminal 9 and a second wiring terminal 10. The first wiring terminal 9 and the first wiring strap 4 are detachably connected, and the second wiring terminal 10 and the second wiring strap 5 are detachably connected. The main wiring strap 8 has a main cable inside, and the main cable and the two cables are electrically connected respectively.
[0030] It should be noted that the installation of communication cables inside the first wiring strip 4, the second wiring strip 5, and the main wiring strip 8 is a common practice in the prior art, and will not be elaborated here.
[0031] The first end of the first connecting strip 4 and the first end of the second connecting strip 5 are both fixedly connected to the fabric substrate 1. The second end of the first connecting strip 4 and the first connecting end 9 are fastened together, and the second end of the second connecting strip 5 and the second connecting end 10 are fastened together. The fastening method and structure here can refer to the fastening methods and structures commonly used in the prior art.
[0032] This application integrates the fabric substrate 1 with microfiber electrodes 2, the first connector 4 with cables, and the second connector 5 with cables into a single unit, with the signal line running inside the cable, resulting in a more stable signal.
[0033] Furthermore, the second end of the first connector 4 can be quickly connected to the first connector 9 of the main connector 8, and the second end of the second connector 5 can be quickly connected to the second connector 10 of the main connector 8. Medical staff can quickly assemble this EIT electrode strap and turn on the power for lung monitoring. In addition, this EIT electrode strap has fewer connection nodes, so there will be no poor contact or communication signal breakage.
[0034] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
