Speed steadily inputs patient's body, to realize the clinical applications such as radiography, treatment.Common powered inj ection class conduit has radiography to lead
The catheter in blood vessel such as pipe, microtubular, support catheter, central venous catheter, implantable drug delivery system and part trocar peripheral catheters.
Angiography catheter etc. is usually used in the operative treatments such as Toluidine blue O diagnosing and treating, for being inserted into vascular system, injection
Or input contrast medium etc. carries out vascular system radiography or operative treatment with diagnostic imaging.Common clinical is applied as coronal dynamic
Arteries and veins radiography, and coronary heart disease (also known as ischemic heart disease) is first of the global cause of death, therefore such conduit clinical application is very
Extensively.Central venous catheter and implantable drug delivery system can provide long-term chemotherapy, intravenous nutrition and route of administration, resistance to height for patient
Pressure central venous catheter is usually used in the drug and nutriment of venoclysis high concentration.
Catheter in blood vessel is the high risk Medical treatment device of state key supervision as human recycle system's interventional medical device
Tool.Wherein, high voltage bearing powered inj ection class conduit is because its injection pressure is higher, injection speed is very fast, injection volume is larger, so
Stability and quality safety under conduit condition of high voltage directly affect clinical operation quality and patient vitals' safety.Therefore, to dynamic
Power, which injects class conduit matter quantifier elimination, has very great clinical application significance.
