Abstract
Blood pump is the core component units of external cardiac devices, and the performance of the function and performance of external cardiac devices is realized by blood pump substantially；So the environmental suitability quality of blood pump depends on that surely entire blood pump environmental suitability is horizontal；It is design, verification and the basis and the foundation that promote blood pump hydraulic performance level that hydraulics test, which is carried out,.Comprehensive function of multiple environmental factors to product can be evaluated in hydraulics test, and test result is true, reliable.Blood pump generally uses in hospital, the use of object is usually Patients with Cardiac Failure, and uses the pathological characters difference of object larger；Therefore the problem of effectively simulating the hydraulics platform of pathological characters, experimental enviroment is made to be more nearly application environment, is badly in need of solving.
Description
Technical field
The invention belongs to bio-medical technology fields, are related to a kind of blood pump hydraulics of external ventricle circulatory assit system
It can test device.By the fluid control component that can be automatically controlled, solve the problems, such as that blood pump environmental test simulation is poor..
Background technology
Blood pump is the core component units of external cardiac devices, the performance of the function and performance of external cardiac devices substantially according to
It is realized by blood pump；So the environmental suitability quality of blood pump depends on that surely entire blood pump environmental suitability is horizontal.
It is design, verification and the basis and the foundation that promote blood pump hydraulic performance level that hydraulics test, which is carried out,.Hydraulics
Comprehensive function of multiple environmental factors to product can be evaluated in experiment, and test result is true, reliable.
Blood pump generally uses in hospital, the use of object is usually Patients with Cardiac Failure, and uses the pathological characters difference of object
It is larger；Therefore the problem of effectively simulating the hydraulics platform of pathological characters, experimental enviroment is made to be more nearly application environment, is badly in need of solution
Certainly.

It manages in simulated slot, therefore is used to control the supply of raw material using the form of switch valve and constant displacement pump.
Drainage control device 24；
Due to when testing hydraulic performance, needing to test different measurands repeatedly, it is therefore desirable to have emptying pathology simulation
The function of slot, therefore it is used to control the action emptied using the form of switch valve.
It should be understood that the above-mentioned specific implementation mode of the present invention is only as citing, that is, spiritual not office of the invention
It is limited to content described in above-mentioned specific implementation mode, and should includes all possible etc. based on above-mentioned specific implementation mode
Effect transformation.
