Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to an electrode belt used for electrical impedance imaging equipment and the electrical impedance imaging equipment. Background Art

[0002] Lung testing can help detect lung diseases at an early stage, including lung cancer, lung infections, and pulmonary fibrosis. Especially for potentially fatal diseases such as lung cancer, early detection of the disease can provide better treatment opportunities and increase the possibility of cure. For patients who have been 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, help adjust treatment plans, and provide better treatment effects. At the same time, lung testing is also suitable for some high-risk groups, such as smokers, people with a family history of lung disease, etc. Regular lung testing can help screen for potential problems and take appropriate preventive measures to reduce the risk of disease development.

[0003] EIT (electrical impedance imaging) is a non-invasive, radiation-free lung ventilation monitoring technology that can be implemented at the bedside. Its basic principle is to apply a weak current through local electrodes to sense the changes in the bioelectrical impedance of the chest during breathing, and then use the corresponding imaging algorithm to monitor the ventilation function status in different areas of the lungs, and present it in real-time dynamic lung tomography ventilation images. EIT is a non-invasive and continuous monitoring technology with the characteristics of non-invasive, radiation-free, continuous monitoring, and low cost. It can realize visualization, continuous dynamic monitoring of the lungs, and perform real-time diagnostic analysis and disease risk prediction at the same time, helping doctors understand the condition, and helping to achieve individualized, visualized lung protection ventilation and individualized precision medicine.

[0004] At present, the EIT monitoring front end uses a separated structure, that is, the monitoring front end is divided into two sections or three sections. Two sections: patient cable + electrode strap; three sections: patient cable + adapter cable + electrode strap. Whether it is two sections or three sections, the electrode strap and cable are separated and need to be fixed by buckle. The use of a separated structure is not only inconvenient to plug and unplug, wasting time, but also due to too many nodes, poor contact will occur, resulting in communication signal disconnection.

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] In the embodiment of the utility model, an electrode belt and an electrical impedance imaging device are provided. In the first aspect, please refer to Figure 1 and Figure 2 The electrode belt used for impedance imaging equipment includes an elastic belt 10, a plurality of wires (not shown in the figure), a plurality of electrodes 20 and a cable 30; each electrode 20 is electrically connected to the cable 30 through a wire, the electrode 20 is fixedly arranged on the elastic belt 10, the wire is integrally formed with the elastic belt 10 and the wire is curved, when the elastic belt 10 is stretched along the length direction of the elastic belt 10 under the action of an external force, the wire can change from a curved state to a straight state, and one end of the cable 30 is fixedly connected to the elastic belt 10.

[0030] According to the electrode belt used for the impedance imaging device in the above embodiment, the wire and the elastic belt 10 are integrally formed, and the wire is curved, and can be changed from a complete state to a straight state as the elastic belt 10 is stretched. The electrode 20 is arranged on the elastic belt 10 and is electrically connected to the cable 30 through the wire. Therefore, the electrode belt used for the impedance imaging device in the utility model can be directly bound to the human body without spending time on assembly operations. In addition, the connection between the electrode 20 and the wire is fixed, so the probability of poor contact is almost zero.

[0031] In some specific embodiments, the elastic band 10 is further provided with a plurality of through holes 110 and fixing columns 120 that fit in with each other. The through holes 110 are arranged along the length direction of the elastic band 10 , and the fixing columns 120 can be inserted into the through holes 110 .

[0032] The electrode belt is used to be tied to the patient's chest, and the electrode 20 is attached to the patient's skin. The chest circumference of different patients is different. Since the elastic belt 10 is elastic, the fixing column 120 is fixed at different through holes 110 to tighten the electrode belt, thereby ensuring that the electrode 20 is always attached to the patient's skin.

[0033] In some specific embodiments, the elastic band 10 includes a first section 130 and a second section 140 that can be snapped together, and the first section 130 and the second section 140 are fixed with the electrodes 20 , the wires and the cables 30 .

[0034] Generally, patients who use electrical impedance imaging equipment are moderate or severe patients, and generally have no ability or difficulty to stand up, so it is difficult to wrap the electrode belt around the patient. By setting the elastic band 10 into a first section 130 and a second section 140 that can be connected to each other, the patient does not need to stand up, and only needs to turn over to complete the wearing of the electrode belt. Of course, the first section 130 and the second section 140 must be equipped with corresponding electrodes 20, cables 30 and wires.

[0035] In some specific embodiments, the through holes 110 are arranged at equal intervals.

[0036] The through holes 110 arranged at equal intervals can facilitate the control of tightness when fixing the through holes 110 and the fixing posts 120. The top of the fixing posts 120 generally has a circular protrusion, which is slightly larger than the diameter of the through holes 110. Since the elastic band 10 is elastic, the through holes 110 can also change in size to a certain extent.

[0037] In some specific embodiments, a tensile wire (not shown) is further included. The tensile wire and the elastic band 10 are integrally formed and curved. When the elastic band 10 is stretched along the length direction of the elastic band under the action of external force, the tensile wire can change from a curved state to a straight state to prevent the wire from being completely straightened.

[0038] The wire is relatively fragile and may break due to excessive stretching of the elastic band 10. Therefore, the tensile wire can prevent the wire from being completely straightened, thereby preventing the elastic band 10 from being overstretched.

[0039] In some specific embodiments, please refer to Figure 1 or Figure 2 , also includes a reference electrode 40, which is electrically connected to the cable 30.

[0040] The reference electrode 40 is used as a reference and is generally not attached to the skin of a human body. This is because the impedance of the electrode 20 is sometimes related to factors such as the ambient temperature, so a reference electrode 40 is provided for reference.

[0041] In some specific embodiments, please refer to Figure 3 The cable 30 further includes a circuit board 310, which is disposed at one end close to the elastic band 10. The circuit board 310 is provided with pins 3110 corresponding to the number of electrodes 20, and the pins 3110 are electrically connected to the wires.

[0042] In this embodiment, the pins 3110 on the circuit board 310 are electrically connected to the wires, thereby supplying power to the electrodes 20 .

[0043] In some specific embodiments, the circuit board 310 further includes an encryption module 3120 , which can encrypt the data collected by the electrode 20 .

[0044] The encryption module 3120 is generally an encryption chip, which can collect, summarize and encrypt the information collected by the electrode 20. It is mainly used to prevent the leakage of relevant intellectual property rights and trade secrets and ensure the market share of the manufacturer.

[0045] In some specific embodiments, the electrodes 20 are arranged at equal intervals.

[0046] The electrodes 20 are also arranged at equal intervals to ensure consistency in the data measured on the patient's cardiopulmonary condition.

[0047] In some specific embodiments, a positive electrode interface (not shown) and a negative electrode interface (not shown) are provided at one end of the cable 30 away from the elastic band 10 .

[0048] Because the electrical impedance imaging device is to form an electrical circuit, the purpose of monitoring the patient's heart and lungs is achieved by measuring the impedance at the electrode 20. The positive electrode interface is generally connected to the positive electrode, and the negative electrode interface is generally connected to the negative electrode interface, thereby forming a complete circuit. In other words, in general, each electrode 20 corresponds to two wires.

[0049] In a second aspect, the electrical impedance imaging device comprises a main body (not shown) and an electrode belt applied to the electrical impedance imaging device as in any one of the first aspects, and the main body can decode the electrode 20 signal and can be electrically connected to the electrode belt.

[0050] According to an electrical impedance imaging device in the above embodiment, since the electrode belt used for the electrical impedance imaging device of the first aspect is used, medical personnel connect the cable 30 with the main body wire when using it, and the main body decodes the electrode 20 signal transmitted by the cable 30 and performs imaging. Therefore, the electrical impedance imaging device in the utility model can make it easier for patients to complete the electrical impedance imaging operation.

[0051] Finally, it should be noted that the cable 30 is mainly used for signal transmission and power supply, and its function is similar to the data transmission line of a mobile phone. The encryption module 3120 can also be used for authentication protection, that is, only the main device that has been identified and authenticated will transmit the electrode data.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
