MODULAR PULSE DUPLICATOR SYSTEM FOR SIMULATION OF CARDIOVASCULAR HEMODYNAMIC FUNCTIONS

摘要

A versatile multi-function modular pulse duplicator system having multiple modules each universally and fluidly connected to each other via universal connectors. Each module being detachable from another module and the plurality of modules can be rearranged in different sequence or quantity as the user desires for specifically designed hemodynamic simulations. Each module is relatively light-weight, portable, and most are generally rectangular or square in shape. Each module has at least one through channel allowing fluid flow. Some modules have specific functions by having a pump, a compliance chamber, a resistance mechanism, or a fluid reservoir. Most of the modules have two intersecting channels, thereby creating four exiting holes each of which can be selectively shut or made available for connection to other modules. Optional peripheral modules that simulate anatomical subsystems can be fluidly coupled within this system of modules, allowing studying/training/product demonstration in the subsystem specifically provided, under desired cardiovascular hemodynamics. The use of universal connectors, peripheral modules, and selectively attachable/detachable modules, make this a versatile system where a user can design a simulation according to the specifics needed for product testing, product demonstration, surgical training, teaching and researching.
