Problems solved by technology

There are also similar products that can simulate human blood pathways, but they cannot circulate liquids, nor can they simulate arterial pulses.
[0003]The main disadvantage of the existing technology is that it can only realize some functions, or only can puncture, or can only perform pulse simulation, and there is no pulse intensity adjustable function

Embodiment Construction

[0026] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] refer to figure 1 , the simulation model of arteriovenous blood circulation system consists of three parts: circuit control module, fluid circuit module, and model man.

[0028] Circuit control module: including control circuit, keyboard, liquid crystal display and power supply. The control circuit takes the AVR microcontroller ATMEGA32A as the processing core, and the whole function control and data processing. The liquid crystal display is used to display the current state of the model, including pulse intensity and pulse frequency, and the user can set the pulse intensity and frequency through the keyboard. The power supply part adopts the inlet voltage of 12V, and the 12V power supply can be used for power supply of turbine and solenoid valve, and it is stepped down to 3.3V for power supply of single-chi...

Abstract

The invention discloses a simulation model of an arteriovenous blood circuit circulating system, which comprises a circuit control module, a liquid circuit module and a model man. The circuit control module comprises a control circuit, a keyboard, a liquid crystal display and a power supply; the liquid circuit module comprises a charging turbine, a magnet valve, a liquid storage box and a silicone tube; and the model man can perform hose layout according to positions of main arteryies and venae of human body, and also perform layout according to the requirements of a user. The simulation model has a simple mechanical structure and relative low cost, and is applicable to the field of medical teaching instruments.

Description

technical field [0001] The invention relates to the field of medical teaching instruments, in particular to a simulation model of an arteriovenous blood circulation system. Background technique [0002] Among the similar products currently on the market, some products have achieved some functions, such as using gas path pressurization method to realize the simulation of human pulse and pulsation, and replacing blood pulsation with gas pulsation. There are also similar products that can simulate human blood circulation, but cannot circulate fluid or simulate arterial pulsation. [0003] The main disadvantage of the prior art is that only partial functions can be realized, or only puncture, or only pulse simulation can be performed, and there is no pulse strength adjustable function. Contents of the invention [0004] In order to solve the above problems, a simulation model of arteriovenous blood circulation system is provided. This model can highly simulate the circulatio...
