The purpose of the present invention is to make a simple and adjustable electrocardiogram vector signal ring teaching aid to solve the teaching problems of electrocardiogram vectors that commonly plague medical teachers.

In order to achieve the above-mentioned technical purpose and achieve the above-mentioned technical effect, the present invention is realized through the following technical solutions:

A method for designing an adjustable ECG vector signal ring, comprising the following steps:

Step 1) Make the Rope Ring

A said rope-shaped ring is made of plastic material and snapped into a ring;

Step 2) Make a three-headed object

Select two short rods and a long rod, place the two short rods and the long rod into the shape of the adjacent side of the parallelogram and the sandwiched diagonal, and place the The end arrow is installed at the same end of the long rod, the red ball is installed on the end arrow of the long rod, and the two short rods are connected with elastic lines;

Step 3) Make the Telescoping Pole

Select three slender rods to install the end arrows on their heads respectively and make nested structures to form the telescopic rods;

Step 4) Overall Installation

Evenly install a plurality of groups of the three arrow-shaped objects on the rope-shaped ring, and then install three telescopic rods on the middle part of the left side of the rope-shaped ring and make them respectively in three planes, and the three telescopic rods The axle center of above-mentioned telescoping link is set to movable type.

The beneficial effects of the present invention are:

By adopting the technical scheme of the invention, the teaching problem about the electrocardiogram vector that generally plagues medical teachers can be solved.

The above description is only an overview of the technical solutions of the present invention. In order to understand the technical means of the present invention more clearly and implement them according to the contents of the description, the preferred embodiments of the present invention and accompanying drawings are described in detail below.
