Problems solved by technology

The above-mentioned demonstrator has the following defects: it cannot express the physiological structure of the blood circulatory system as a closed pipe; the blood flow is expressed by flashing the demonstration piece, which lacks the sense of blood flow and the dynamic sense is not strong; it cannot express the left atrium, right atrium and left ventricle The physiological phenomenon that the right ventricle contracts and relaxes alternately to promote blood flow
Therefore, the existing demonstrator cannot intuitively and vividly express the relevant physiological structure and physiological phenomena of the blood circulation system of mammals, birds, etc.

Embodiment 1

[0030] Such as Figures 1 to 4 As shown, a blood circulation demonstrator, particularly a demonstrator for demonstrating the blood circulation of mammals and birds, the front of the vertical plate 1 including the support is fixed by a plurality of buckles 12 with self-tapping screws and connected in sequence Transparent and transparent left atrium demo19, left ventricle demo23, aorta demo, tissue capillary demo25, upper and lower extremity vein demo, vena cava demo, right atrium demo9, right ventricle demo24 , Pulmonary Artery Demonstration, Pulmonary Capillary Demonstration 13, Pulmonary Vein Demonstration.

[0031] The left atrium demonstration piece 19 on the upper side, the right atrium demonstration piece 9 and the left ventricle demonstration piece 23 on the lower side, and the right ventricle demonstration piece 24 are all made of rubber materials, which are hollow and approximately spherical. The left atrium demonstration piece 19 and the left ventricle demonstration p...

Embodiment 2

[0039] A blood circulation demonstrator, especially a demonstrator for demonstrating the blood circulation of mammals and birds, its main composition structure is the same as that of Embodiment 1, only the transmission mechanism is different from that of Embodiment 1. Same, the specific transmission mechanism of the present embodiment is as follows:

[0040] Such as Figure 11 , the rear side of the vertical board 1 is provided with an electric transmission mechanism that can make the left atrium demonstration piece 19, the right atrium demonstration piece 9, the left ventricle demonstration piece 23, and the right ventricle demonstration piece 24 contract and relax alternately, and the transmission mechanism includes Connecting rod 55, upper limit flap 33, connecting seat 34, lower limit flap 33, motor 51, wheel disc 52, boss 54;

[0041] The motor 51 is fixed on the bottom of the vertical plate 1, the front end of the rotor of the motor 51 is welded to the center position o...

Embodiment 3

[0055] Such as Figure 12 As shown, a blood circulation demonstrator, especially a demonstrator for demonstrating the blood circulation of fish animals, the front of the vertical plate 1' including the bracket is fixed by a plurality of buckle bars 12' with self-tapping screws to communicate with each other in turn. And transparent atrium demonstration part 58, ventricle demonstration part 57, dorsal artery demonstration part 59, tissue capillary demonstration part 64, vein demonstration part 60, gill capillary demonstration part 61, the vertical plate 1 ' surface of the atrium demonstration part 58 rear side There are pits, and there are two through holes in the two pits on the upper side of the vertical plate 1. There are also pits on the surface of the vertical plate 1' on the rear side of the ventricular demonstration piece 57, and there are holes on the front and rear end surfaces of the vertical plate 1' that pass through through hole.

[0056] The upper atrium demonstr...

Abstract

The invention discloses a blood circulation demonstrating device. The blood circulation demonstrating device is characterized in that all demonstrating parts which are arranged on one lateral side of a vertical plate of a support and represents physiological structures of a blood circulation system of an animal are hollow and are connected in sequence to form a closed pipeline, the pipeline is filled with liquid, both an atrium demonstrating part and a ventricle demonstrating part are made of elastic materials, and a transmission mechanism enabling the atrium demonstrating part and the ventricle demonstrating part to contract and relax in an alternating mode is arranged on the other lateral side of the vertical plate. The blood circulation demonstrating device can visually and vividly represent the relevant physiological structures and physiological phenomena of the blood circulation system of the animal.

Description

technical field [0001] The invention provides a blood circulation demonstrator, in particular to a blood circulation demonstrator for animals such as mammals or birds, and a blood circulation demonstrator for fish animals. Background technique [0002] The structure of the existing blood circulation demonstrator for animals such as mammals or birds is as follows: a left atrium demonstrator, a left ventricle demonstrator, an aorta demonstrator, a tissue capillary demonstrator, Vein demo, vena cava demo, right atrium demo, right ventricle demo, pulmonary artery demo, pulmonary capillary demo, pulmonary vein demo; the blood circulation demonstrator structures of fish animals are: ventricle demo, aorta Demonstration piece, upper and lower extremity vein demonstration piece, gill artery demonstration piece, gill vein demonstration piece, said demonstration pieces are all light-emitting elements (such as light-emitting diodes, neon tubes, etc.) electrical connection. After the p...
