[0024] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0025] Please refer to Figs. 1-2The utility model provides a kind of portable human body simulation test model 10 for EIT electrode imaging equipment, including the tomographic model 100 made of conductive material, left lung model 200 and right lung model 300, left lung model 200 and right lung model 300 can be respectively detachably arranged in tomographic model 100, tomographic model 100 has display surface 130, display surface 130 has the direction indicating mark 131 matched with EIT electrode imaging equipment, for simulating the electrical impedance characteristic of human thoracic tomography.

[0026] Specifically, tomographic model 100 is used as the basic framework of simulating human thoracic tomography, and one side of the tomographic model 100 is provided with a display surface 130, and the display surface 130 is provided with direction indicating marks 131 (such as "A" (front), "P" (back), "R" (right) and "L" (left)) matched with the EIT electrode imaging equipment, to ensure the accuracy of the model direction. The left lung model 200 and the right lung model 300 can be detachably mounted in the tomographic model 100. The entire portable human body simulation test model 10 for the EIT electrode imaging equipment is made of light conductive material, which can not only accurately simulate the electrical impedance characteristic of human thoracic tomography, but also realize the simulation of different lung ventilation states (single-lung or double-lung ventilation) by plugging in and out the right lung model 300, thereby meeting the diversified needs of the EIT electrode imaging equipment in testing and display. The portable human body simulation test model 10 for the EIT electrode imaging equipment is made of light material, which is light in weight and easy to carry, and is suitable for exhibitions and rapid deployment. Through the detachable design of the left lung model 200 and the right lung model 300, the operation steps are simplified, and flexible simulation of single-lung or double-lung ventilation state is realized. The direction indicating marks 131 on the display surface 130 improve the intuitiveness of the model use, and avoid imaging deviation caused by wrong direction. In addition, the model has simple structure and low production cost, and can be produced in small batches through the mold replication process, which meets the distributed promotion needs and significantly improves the application efficiency of the EIT equipment in the research and development, display and promotion links.

[0027] It should be noted that EIT (Electrical Impedance Tomography) is a non-invasive technology that measures the electrical conductivity distribution changes inside an object or a human body to perform imaging, and is widely used in medical imaging and industrial detection fields. To realize the development and application of EIT equipment, the test model plays an important role in verifying the performance of the equipment, displaying the functions of the equipment and promoting the products. In addition, please refer to Fig. 1 and Fig. 2 According to the interactive logic of EIT, the portable human body simulation test model for the EIT electrode imaging equipment is left-right reversed, i.e. mirror image.

[0028] It needs to be understood that in order to overcome the shortcomings of the existing water medium test model in terms of portability, ease of operation and display effect, the traditional water medium model is large in size, heavy in weight, requires complex water injection and sealing operation, and is difficult to meet the needs of efficient display scenarios such as exhibitions; at the same time, the simulation effect of the existing model is not intuitive enough, and the monitoring ability of the EIT electrode imaging device for the ventilation state of the human chest cannot be clearly displayed. In order to solve the above problems, the portable human body simulation test model 10 for EIT electrode imaging device is made of light conductive material, which significantly reduces the weight of the model and improves the portability; through the detachable design of the left lung model 200 and the right lung model 300, flexible single-lung or double-lung ventilation state simulation is realized, and the intuitiveness of the display is enhanced.

[0029] In the present embodiment, the tomographic model 100, the left lung model 200 and the right lung model 300 are all shaped to fit the human body contour.

[0030] Specifically, the tomographic model 100, the left lung model 200 and the right lung model 300 are all designed to fit the shape of the human body contour, so as to be closer to the actual anatomical structure of the human chest, so that the test model can better simulate the morphological characteristics of the human chest in appearance and function, especially the shape and size of the right lung and the right lung are consistent with the real anatomical characteristics, so that the EIT electrode device can more intuitively show the real impedance distribution state of the human chest during testing or display. In addition, the shape fitting the human body contour helps to correctly arrange the electrodes and improve the accuracy of signal acquisition, further improving the reliability of the device testing and display effect.

[0031] In the present embodiment, the tomographic model 100, the left lung model 200 and the right lung model 300 are all made of light conductive silicone material.

[0032] Specifically, the model made of light conductive silicone material greatly reduces the overall weight of the model and significantly improves its portability, so that users can more easily carry and deploy it in exhibitions, promotional activities or testing scenarios. In addition, the flexibility and processability of silicone material enable the model to be produced in small batches through simple molding process, effectively reducing production cost while ensuring the structural strength and functional stability of the model.

[0033] In the present embodiment, the tomographic model 100 includes a left lung slot 110 and a right lung slot 120, the left lung model 200 is arranged in the left lung slot 110, and the right lung model 300 is arranged in the right lung slot 120.

[0034] Specifically, by arranging the left lung slot 110 and the right lung slot 120 in the tomographic model 100, the left lung model 200 and the right lung model 300 are provided with fixed positions, so that the internal structure of the model is more regular, and the operability and display effect of the model are improved.

[0035] In the embodiment, the shape and size of the left lung model 200 are adapted to the left lung groove 110, and the shape and size of the right lung model 300 are adapted to the right lung groove 120.

[0036] Specifically, by adapting the left lung model 200 to the left lung groove 110 and the right lung model 300 to the right lung groove 120, good mechanical matching can be provided during installation and use, and the models can be prevented from loosening or mispositioning. This design also ensures that the internal structure of the simulation model can accurately reproduce the actual anatomical state of the human lung, thereby further improving the testing and display accuracy of the EIT electrode imaging device.

[0037] In the embodiment, the tomographic model 100 is provided with anti-slip textures on the inner walls of the left lung groove 110 and the right lung groove 120.

[0038] Specifically, by providing anti-slip textures on the inner walls of the left lung groove 110 and the right lung groove 120, the left lung model 200 and the right lung model 300 can be effectively prevented from sliding or loosening during installation, and the models can be ensured to remain stable during use, so that the EIT electrode imaging device can more stably collect data and show the ventilation state during testing or display.

[0039] In the embodiment, the left lung model 200 has a left plane 210, which is flush with the display surface 130 when the left lung model 200 is arranged in the tomographic model 100; and the right lung model 300 has a right lung plane 310, which is flush with the display surface 130 when the right lung model 300 is arranged in the tomographic model 100.

[0040] Specifically, the left plane 210 and the right lung plane 310 are flush with the display surface 130, which can optimize the flatness and integrity of the appearance of the models, and enable the EIT electrodes to be accurately and stably attached to the display surface 130 and the corresponding lung model area. This flush design helps to avoid poor electrode attachment or data collection errors, and ensures that the EIT device can normally collect impedance data corresponding to the simulated state during testing and display.

[0041] In the embodiment, the left lung groove 110 is provided with a first left lung opening and a second left lung opening, the first left lung opening is close to the display surface 130, the left lung model 200 is arranged in the left lung groove 110 by being pushed through the first left lung opening, and the left lung model 200 is separated from the left lung groove 110 by being pushed through the second left lung opening. The right lung groove 120 is provided with a first right lung opening and a second right lung opening, the first right lung opening is close to the display surface 130, the right lung model 300 is arranged in the right lung groove 120 by being pushed through the first right lung opening, and the right lung model 300 is separated from the right lung groove 120 by being pushed through the second right lung opening.

[0042] Specifically, by setting the first left lung port and the second left lung port and adopting the flat push type installation design, the loading and unloading process of the left lung model 200 is simplified. The first left lung port is close to the display surface 130 and is used for the loading operation of the left lung model 200, and the second left lung port is located at the other end of the left lung groove 110 and is used for the unloading operation of the left lung model 200. The left lung model 200 is loaded into the left lung groove 110 through the flat push type, and is pushed out of the left lung groove 110 through the second left lung port, so that the quick installation and unloading of the model are realized. Conversely, the left lung model 200 can also be installed from the second left lung port and unloaded from the first left lung port. The loading and unloading process of the right lung model 300 is the same as that of the left lung model 200, and thus is not described again.

[0043] In the embodiment, the display surface 130 is provided with installation marks for fixing the EIT electrodes.

[0044] Specifically, by setting the installation marks on the display surface 130, the operator can be intuitively guided to accurately position and fix the EIT electrodes on the model. This design effectively avoids the inaccurate test data or equipment imaging error caused by the deviation of the electrode installation position, reduces the requirement for the professional skills of the operator, and improves the efficiency and accuracy of the electrode installation.

[0045] Of course, the utility model can also have other various embodiments, and other embodiments obtained by the person skilled in the art based on the embodiment without any creative labor belong to the range protected by the utility model.
