Multifunctional modularization blood flow dynamics analog device

Abstract

The invention discloses a multifunctional modularization blood flow dynamics analog device. The device comprises a plurality of detachable and assembled modules with different functions. Each module possesses at least one channel. The plurality of modules can be connected with each other through the at least one channel so as to form a fluid of fluency circulation. One module of the plurality of modules is a pump module which is arranged on the fluid and possesses a linear motor. The pump module simulates contraction and diastole of a ventricle through a mode of driving the fluid based on waveform driving. The plurality of modules can be split into many free and independent modules, or be rearranged via different simple sequences or can realize different functions through accessing one or more additional modules. Through at least one channel, mutual connection is achieved and a new fluid is formed. The additional modules possess at least one channel. Each module provides a specific function and the above functions can be integrated into one multifunctional module.

Description

technical field [0001] The invention relates to a device for testing, using training and environment simulation of medical equipment, in particular to a multifunctional modular hemodynamics simulation device, which is mainly used for scientific research, training and displaying user products. Background technique [0002] The study of blood flow problems has great significance and application value. Many experiments and clinical applications in medicine, as well as the design and development of biomedical instruments and products, can all get help from the study of blood vessel inlet flow. The pulsating flow simulation system in 20 It was introduced in the 1980s as a tool for evaluating the hydrodynamic properties of prosthetic heart valves. It was also later used in various simulated blood circulation. However, existing systems can only implement a specific single analog function. For example, a pulse simulator designed for surgical valve testing and not all-around for ot...

AI Technical Summary

Problems solved by technology

Attempts to use it for any other application, such as simulating stent delivery, would inevitably require irreversible design changes and experimentation, often resulting in a complete redesign of the original pulse simulant

Modifications require time, expense, and expertise, yet purchasing or designing separate analog units for each analog function makes the cost too expensive to be feasible for most users
