A NON-INVASIVE AUTOMATIC DETECTING SYSTEM FOR BLOOD FLOW PARAMETERS OF CARDIOVASCULAR SYSTEM

In this paper,a non-invasive detecting system for measuring blood flow parame-ters of cardiovascular system is described.The device employs a new unique methodwhich is based on the theory of hemodynamics,ordinary measurement of blood pres-sure and pulse information of variation of pulse contour parameter Ko The sphygmo-gram is picked up from radial artery via sensor.As the blood pressure changes,the

THE RESEARCH OF FLOW CONTROLLED SYSTEM FOR CONTINUOUS CYCLIC PERITONEAL DIALYSIS (CCPD)

Peritoneal dialysis is widely used in clinical practices.The flow controlled sys-tem we have developed is completely under computer control.In order to be as simpleas possible,we use only one valve to control the three stages of peritoneal dialysis,that is the infusion,dwell,and drainage of dialysate.In clinical application the wholetime during which the pipeline is shut is about 8-10 hours for every treatment.In or-der to avoid the phenomenon that the pipeline can't open after it was closed for too
