Description
Technical field
The present invention relates to a kind of plugging type veins indwelling catheter, belong to blood purification or intravenous drip field of medical device.
Background technology
Before the dialysis of part dialysis patient, need patient is carried out central vein placement catheter, for patient's Reusability, subtract
Few patient suffering.After having dialysed, need vein detaining catheter is blocked, generally use injecting heparin in indwelling tube, with
Solve blood coagulation problem, it is ensured that after patient opens vein detaining catheter next time, there is no blood coagulation in vein detaining catheter, it is possible to be normally carried out
Analysis.For general intravenous injection, there is section of vein to puncture inconvenient patient and be also required to carry out vein detaining catheter heeling-in, for
Injection repeatedly.
Prior art uses injecting heparin to place blood coagulation and has following defects that
1, because of individual variation, the control of the most difficult of heparin injections amount, there is potential safety hazard and medical-risk: heparin injections is in meditation
After in arteries and veins indwelling tube, connecting with blood, unavoidably there is the disperse of heparin and blood, heparin can flow into patient's body therewith
Interior entrance blood samples of patients circulates, and blood also can flow in vein detaining catheter.If the heparin amount of injection is little, does not then reach and prevent
The effect of blood coagulation, when dialysing or inject, however it remains sludged blood, if sludged blood enters blood samples of patients circulation, then next time
Some tissue thromboembolism of patient may be caused.If the heparin amount of injection is excessive, then heparin flows into therewith and carries out patient in the patient
Blood circulation, may cause patient's blood coagulation disorders, if hemorrhagic conditions occurs in patient, especially during internal hemorrhage disease, it is difficult to only
Blood, causes medical-risk.
2, operation easier is big, and cost is high.Injecting heparin is single use, discarded after use.The handle of injection volume
Holding the operating experience being heavily dependent on medical personnel, operation easier is big.
Summary of the invention
It is an object of the invention to provide a kind of plugging type veins indwelling catheter, it is possible to effectively block veins indwelling catheter, keep away
Exempt from blood clotting, patient is not damaged, use safer.
