Description
Technical field
The utility model relates to medical instruments fields, and in particular to a kind of blood dialysis circuit pipe.
Background technique
Existing hemodialysis pipeline is made of an artery pot, a dialyzer, a venous chambers and relevant pipeline.
In blood dialysis, when there is mild or moderate blood coagulation phenomenon in duct of Arantius, can by wash away venous chambers make dialysis continue or
Person does sth. in advance to terminate the hemodialysis of patient, and when serious blood coagulation then needs to continue blood with changing blood dialysis circuit Guan Caineng
Dialysis；And dialyzer can only can just make blood by cutting off dialyzer, and by disinfection, conduit docking when there is blood coagulation phenomenon
It flows back into patient body.These can all make dialysis treatment that must not obtain desired effect, and venous chambers and dialyzer blood occur serious solidifying
Blood can not be fed back in patient body when blood, even if the risk for also having blood to pollute by many and diverse operation blood back, makes the state of an illness of patient
It aggravates.It is higher to operator's technical requirements meanwhile when haemodialysis, when replacing bag of saline and needle catheter in a short time, easily
The fracture for causing connecting pin causes dialysis treatment that can not be normally carried out.
Utility model content
For the utility model in order to overcome drawbacks described above existing in the prior art, providing one kind can guarantee that patient continuously pacifies
The blood dialysis circuit pipe of hemodialysis is completed entirely.
To solve the above problems, the utility model proposes a kind of blood dialysis circuit pipe, including connection arterial duct
Arterial end, artery pot, dialyzer, venous chambers and the vein end for connecting ductus venosus, a dialyzer side bypass duct in parallel,
A spare venous chambers in parallel by the venous chambers, the vein end are Y type port.
Further, strainer is equipped in the artery pot.
Further, a spare artery pot in parallel by the artery pot.
Further, the venous chambers are equipped with strainer, pressure monitor and exhaust pipe, and the strainer setting goes out in venous chambers
At liquid mouth, the upper end of venous chambers is arranged in the pressure monitor and exhaust pipe.
Further, the vein end and arterial end 1 are stamped calparine cap.
Further, one of port of Y type port is connect with venipuncture needle or bag of saline.
Further, the arterial end is connect with arterial puncture needle or bag of saline.
Further, the spare venous chambers use structure identical with venous chambers.
The utility model has the advantages that compared with prior art and advantage:
1, spare venous chambers in parallel by venous chambers, equivalent to increase emergency bypass, when there is blood coagulation phenomenon in venous chambers,
Emergency bypass is opened, treatment can be made to continue, to guarantee that patient uninterruptedly receives dialysis treatment.
2, artery pot is interior is equipped with strainer, can prevent condensation clot from blocking dialyzer, the spare artery pot of parallel connection by artery pot,
Emergency bypass is provided, guarantees that haemodialysis is normally carried out.Parallel branch pipe by dialyzer prevents serious blood coagulation from causing dialyzer stifled
When plug, dialysis treatment can not be normally carried out, and blood can not be fed back in patient body, lead to the serious consequences such as aggravation.
3, vein end uses Y type port, equivalent to increase spare branch pipe, in dialysis procedure, and venipuncture needle replacement
Easily occur vein end fracture when bag of saline, venipuncture needle can not be connected, this unexpected hair can be prevented using Y type port
It is raw, avoid dialysis treatment that from can not carrying out, and blood can not be fed back in patient body.
The utility model ensure that blood coagulation phenomenon occurs in blood dialysis circuit pipe by spare venous chambers in parallel, bypass duct
When, dialysis treatment be normally carried out or blood recovery in patient body, while mitigating the burden of operator；The utility model medium sized vein
When end ensure that misoperation causes vein end to be broken using Y type port, hemodialysis is normally carried out.
