Abstract

A model for medical studies depicting the blood supply and drainage systems of the head, leading to and from the heart. The model includes a head shell which preferably is open at one side so that spacial relationships of the various arteries and major veins may be clearly perceived. The head shell is preferably transparent. Structure simultating dura tissue enclosures are also used.

Claims

1. A medical model depicting blood supply and drainage systems of the head area of a human being, including, in combination, a base, a transparent, half head shell supported above said base, said head shell being open on one side, first structure depicting the entire circle of Willis disposed medially within said shell and protruding out of said shell beyond said open one side, means supporting said first structure above said base, second structure simulating the superior sagittal vein disposed longitudinally along and within said shell at an upper area therein, color-coded vein simulating means connected to said second structure and directly mounted to said base, and color-coded arterial simulating means connected to said first structure and directly mounted to said base.

2. The model of claim 1 wherein said model includes third structure simulating the upper portion of the spinal column of a human being, said third structure being supported from and above said base, said arterial simulating means including means simulating vertebral arteries disposed proximate said third structure in accordance with the positioning of the vertebral arteries of a human being relative to his upper spinal column.

3. Structure according to claim 1 wherein screen-mesh structure encases said second structure simulating said superior sagittal vein, whereby to simulate the dura tissue structure of a human being proximate this area.

4. Structure according to claim 1 wherein screening encases portions of said vein simulating means, visually suggesting the tissue enclosure of a portion of said vein simulating means.

5. Structure according to claim 1 wherein said base forms an integral part of said head shell, being supportive thereof.

6. The model of claim 1 wherein said model includes fourth structure simulating the aorta and superior vena cava of the heart, said structure being mounted to said base, said vein simulating means and arterial simulating means being connected to and supported by said fourth structure.

7. Structure according to claim 1 wherein said arterial simulating means includes structural branches simulating the anterior, middle and posterior cerebral arteries.

8. Structure according to claim 1 wherein said vein simulating means include jugular veins coupled to said superior sagittal vein second structure.

9. A medical model depicting blood supply and drainage systems of the head area of a human being, including, in combination, a base;

a transparent shell, representing essentially half of the head, supported above said base, said shell being, at least in part, open on one side;

first structure depicting the complete circle of Willis disposed medially with respect to said shell and protruding laterally outwardly therefrom;

second structure, representing the arterial system of the head area, integral with and depending from said first structure and supportively attached to said base; and

third structure representing the venous system proximate the said head area, upstanding from and supportively attached to said base.

10. Structure according to claim 9 wherein said model also includes a vertically oriented, transparent falx representatIon, said third structure including an elongate portion, representing the superior sinus, disposed proximate said falx representation at an upper region thereof.

11. Structure according to claim 9 wherein said model includes formed structure, representing the tentorium, disposed medially within said shell.

12. Structure according to claim 9 wherein said second and third structures comprise formed wires which include plural tag identification indicia extending laterally therefrom.
