Description
Technical field
The present invention relates to PICC nursing device fields, are specifically related to a kind of three-tube type PICC nursing device.
Background technique
PICC ductus venosus, can long-time indwelling patient it is intravenous, can obvious less patient fluid infusion's puncture time, facilitate defeated
Liquid treatment, is received by patient and medical staff gradually.According to patient disease needs, some diseases need long-term infusion, some
Tumor patient needs to be used for multiple times chemotherapeutics, some patients are advanced tumor, may need to rescue life at any time, infusion is controlled
It treats, is both needed to one venous access of indwelling, indwelling PICC conduit is the best selection of patient, and PICC is that periphery central vein is set
Pipe, not only can Preserving time, but also stimulation of the chemotherapeutics to wall of vein can be reduced, facilitate infusion, such as discomfort without exception, indwelling
Time is 1 year, but after PICC conduit Preserving time, is easy blocking, leads to nursing after blocking again, PICC pipe is needed to connect three
Logical one interface of device, another interface inject red cell morphology in urine, another interface, empty needle cylinder aspirates the blood clot after thrombolysis,
In suction nursing blocking PICC pipe process, three-way interface need to be adjusted, injects red cell morphology in urine, and suction urine using syringe repeatedly
The dissolved thrombus of kinases, and manually keep swabbing pressure for a period of time, it picks up and carrys out extremely cumbersome, the nursing unobstructed knot of PICC pipeline
Beam, operator is typically due to repeatedly suction and injecting urokinase causes hand sour, hand pain, brings certain be stranded to operator
It disturbs.
