Description

[0001] Equipment of education for vascular surgery [0002]

More particularly, the present invention relates to a blood vessel photographing training apparatus, and more particularly, to a blood vessel model depicting the same as an actual blood vessel, It is possible to precisely understand the anatomical model and position, so that it can be practiced stereoscopic and realistic practice, and it is possible to increase the accuracy of actual photographing through the same repetition practice as the actual photographing, Thereby minimizing the amount of exposure.

On November 8, 1895, Wilhelm Conrad Roentgen discovered X-rays in the course of studying cathode ray. Radiation was then used in medicine to easily diagnose the internal information of the human body such as bones and organs. Gave a revolution. However, in the early days when radiation was discovered, radiation hazards were not known to those who treated the radiation, resulting in death or disability due to radiation exposure.

The International Commission on Radiological Protection (ICRP), which was established in 1928 as a result of increasing radiation hazards, continuously recommended and recommended dose limits, which have been recognized internationally as obstacles to national radiation safety management Prevention.

 In Korea, since the National Health Insurance System was implemented on July 1, 1989, the use of radiation in the medical field has been rapidly increasing. As a result, the exposure of radiation workers, radiation workers, It is increasing day by day.

Among the medical applications using radiation, the diagnosis and interventional procedures of blood vessels are becoming specialized, and the scope of application is also continuously expanding, showing an annual growth rate of 10 to 20%. This means that continuous and long-term exposure to radiation is increased, and the expansion of X-ray use increases the exposure dose, which leads to an increase in radiation damage.

In particular, blood vessels are diagnosed and treated with a long duration of time and many consecutive shots, so they receive a relatively high dose compared to other fields. Therefore, the best method for minimizing the exposure dose during vascular examination is . Therefore, it is emphasized that the education needs of professional radiologists and radiation workers to become a radiation specialist in the medical field and to grow the radiation field into an important occupational group of society.

Regular schools that study the human body such as human anatomy, human physiology, and human pathology are taught to students in many departments from 2 years to 6 years in addition to medical schools. The long - term model of the human body has been used in many education fields since there are various anatomical models.

However, among the long-term models of various human bodies, the model of the apparatus for viewing the blood vessels of the heart as a perspective image has not been studied or developed yet. Among the concepts of the scientific domain, natural selection, diffusion, genetics, net, and respiration show abstract attributes that are difficult to observe or experience directly with the eyes, and show the properties of the process - equilibrium category according to the ontological category. The concepts of these attributes are known to be difficult for students to understand and not change well into scientific concepts after class.

In other words, rather than experiencing the human body through anatomy, it is memorized through the pictures and diagrams of the textbooks. In the case of radiology, for example, without actually seeing the liver, such as tomography, magnetic resonance imaging, and ultrasonography.

Therefore, even in the case of radiology, the perspective image of the blood vessel is disadvantageous in that it can be seen only through photographs or a schematic drawing through a textbook and a short clinical hospital practice. In order to educate radiologists and nurses who can not directly see the structure of blood vessels, There is a high need for the development of model equipment.
