Abstract

1. Устройство для обучения диагностике патологии внутренних органов методом эхоконтрастирования, отличающееся тем, что содержит резервуар с прозрачной эластичной крышкой и размещенную в нем на середине высоты систему, образованную бифуркациями и соустьями трубок, диаметр которых уменьшается с 10 мм на периферии до 2 мм в центре, с дозатором на входе и запирающимся сливом на выходе, образующую два независимых контура в центре системы, один из которых, сосудистый, воспроизводит кровоснабжение паренхиматозных органов и выполнен в виде попарно соединенного ряда трубчатых гексагональных элементов, образованных бифуркациями третьего порядка подающей трубки сосудистого контура и соустьями первого порядка отводящей трубки сосудистого контура, а второй контур, патологический, моделирует кровоснабжение патологических очагов и выполнен в виде двух трубчатых гексагональных элементов, образованных бифуркациями второго порядка подающей трубки патологического контура и соустьями первого порядка отводящей трубки патологического контура и взаиморасположенных таким образом, что их соседние стенки соприкасаются на всем протяжении, и движение эхоконтрастного вещества в них идет в противоположных направлениях, а кровоснабжение патологических очагов смоделировано в виде трех трубчатых петель на отводящей трубке патологического контура, при этом петля, моделирующая аневризму, образует посредине эллипсоидное расширение, петля, моделирующая метастаз образует клубок, входящая в него трубка идет в центр клубка, а выходящая - по его наружной поверхности и петля, моделирующая гемангиому, также образует клубок, но входящая в него1. A device for teaching the diagnosis of internal organs pathology by echo contrast method, characterized in that it contains a reservoir with a transparent elastic cap and a system placed in it at a mid-height, formed by bifurcations and anastomoses of tubes, the diameter of which decreases from 10 mm in the periphery to 2 mm in the center , with a dispenser at the inlet and a lockable drain at the outlet, forming two independent circuits in the center of the system, one of which, the vascular, reproduces the blood supply to the parenchymal organs and is made in the form of pairs about a connected series of tubular hexagonal elements formed by third-order bifurcations of the supply tube of the vascular circuit and the first-order fistulas of the discharge tube of the vascular circuit, and the second pathological pathway models blood supply to pathological foci and is made in the form of two tubular hexagonal elements formed by second-order bifurcations of the pathological supply tube contour and anastomoses of the first order of the discharge tube of the pathological contour and mutually located in such a way that their adjacent walls are in contact throughout, and the movement of the echo-contrast substance in them goes in opposite directions, and the blood supply to the pathological foci is modeled in the form of three tubular loops on the discharge tube of the pathological contour, while the loop simulating an aneurysm forms an ellipsoid expansion in the middle, a loop simulating metastasis forms a tangle, the tube entering it goes to the center of the tangle, and the outgoing tube forms along the outer surface and the loop simulating hemangioma also forms a tangle, but entering shcha in him

Claims

1. A device for teaching the diagnosis of internal organs pathology by echo contrast method, characterized in that it contains a reservoir with a transparent elastic cap and a system placed in it at a mid-height, formed by bifurcations and anastomoses of tubes, the diameter of which decreases from 10 mm in the periphery to 2 mm in the center , with a dispenser at the inlet and a lockable drain at the outlet, forming two independent circuits in the center of the system, one of which, the vascular, reproduces the blood supply to the parenchymal organs and is made in the form of pairs about a connected series of tubular hexagonal elements formed by third-order bifurcations of the supply tube of the vascular circuit and the first-order fistulas of the discharge tube of the vascular circuit, and the second pathological pathway models blood supply to pathological foci and is made in the form of two tubular hexagonal elements formed by second-order bifurcations of the pathological supply tube contour and anastomoses of the first order of the discharge tube of the pathological contour and mutually located in such a way that their adjacent walls are in contact throughout, and the movement of the echo-contrast substance in them goes in opposite directions, and the blood supply to the pathological foci is modeled in the form of three tubular loops on the discharge tube of the pathological contour, while the loop simulating an aneurysm forms an ellipsoid expansion in the middle, a loop simulating metastasis forms a tangle, the tube entering it goes to the center of the tangle, and the outgoing tube forms along the outer surface and the loop simulating hemangioma also forms a tangle, but entering the tube that goes into it goes along the outer surface of the ball, and the one that goes out comes from its center.

2. The device according to p. 1, characterized in that the vascular circuit has the ability to rotate along the axis, and the pathological is fixed in the tank motionless.

3. The device according to p. 1, characterized in that the length of the vascular contour should be less than the height of the tank.
