Artery simulator relevant to magnetic suspension and method implemented by artery simulator

Abstract

The invention relates to the technical field of teaching equipment for medical treatment and public health, in particular to an artery simulator relevant to magnetic suspension. The artery simulator comprises a shell and a pulse generator, and is characterized in that a main pulse magnet is arranged on the lower portion of the shell or inside the shell, a concave support is disposed at the bottom of the main pulse magnet, a suspension force magnet is arranged on the concave support, extending blocks are arranged on bumps at outer edges of the concave support, a driving coil is disposed on the extending blocks, and an electrode is arranged on the driving coil and is connected with a signal output end of the electronic pulse generator. Driving current is transmitted into the driving coil via the electrode, so that electromagnetic driving force is generated, the main pulse magnet starts to move up and down under the action of the electromagnetic driving force, and simulated artery pulses of a human body are generated. The artery simulator has the advantages of low noise, consumption and cost, small size, simple and firm structure, wide kinetic energy adjustment range, difficulty in damage, and the like, and can be widely applied to modern teaching equipment and instruments.

Description

[Technical Field] [0001] The invention relates to the technical field of medical and health teaching equipment, in particular to a magnetic levitation artery simulator. [Background technique] [0002] "Arterial simulator" is a device that can simulate the pulsation of human arteries. It is mainly used in modern medical education. It can vividly show students the arterial pulsation state of the human body and experience the pulsation law of human arteries and the feeling of touch during pulsation. Similar devices on the market mainly include pneumatic, hydraulic, moving coil, electromagnetic, cam type, etc. according to their working principles. Foreign companies such as Gaumard in the United States and Laerdal in Norway now generally use moving coil and pneumatic types. The main shortcomings of these technologies currently being applied are large noise, large volume, high power consumption, insufficient kinetic energy, complex structure, easy damage, high cost and other shortcomi...

AI Technical Summary

Problems solved by technology

The main shortcomings of these technologies currently being applied are that they are noisy, large in size, high in power consumption, insufficient in kinetic energy, complex in structure, easily damaged, and high in cost. For example, the pneumatic type requires a larger air pump as Air source, high energy consumption, high cost and high noise

The moving coil type is not suitable for the simulation of children's arm arteries due to the cumbersome electrode leads, difficult production, large volume, and relatively insufficient power, especially if the volume is small.

[0003] Domestic patent CN201035807Y discloses an anthropomorphic robot pulse beating machine. The pulse beating machine simulates the beating of the pulse through a vibration motor combined with a chip control program, and is also equipped with a sound to simulate the beating of the pulse. There is a difference, and it cannot simulate the real situation of the pulse well
