Below in conjunction with accompanying drawing of the present utility model, the technical scheme in this utility model embodiment is carried out clear, complete description, it is clear that described embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.
Referring to Fig. 1, the extracorporeal circulation pipeline of a kind of apparatus for purifying blood, including the tremulous pulse needle base 1 being sequentially connected with, tremulous pulse supervisor 4, blood pump pipe 6, tremulous pulse kettle 7, dialyser 8, venous chambers 9, vein supervisor 10 and vein needle base 12；
One end of the described tremulous pulse supervisor 4 described tremulous pulse needle base 1 of connection is provided with tremulous pulse supervisor's safety clamp 2；It is responsible for safety clamp 2 to blood pump pipe 6 direction by described tremulous pulse, described tremulous pulse supervisor 4 is sequentially provided with and rushes side pipe 3 and arterial blood pressure monitoring side pipe 5 in advance；
One end of the described vein supervisor 10 described vein needle base 12 of connection is provided with vein supervisor's safety clamp 11；
Described venous chambers 9 is provided with and its internal venous pressure monitoring side pipe 16 connected.
Further, the distance that described tremulous pulse needle base 1 and described tremulous pulse are responsible for safety clamp 2 is 1cm～2cm, the blood hold-up between described tremulous pulse needle base 1 and described tremulous pulse supervisor's safety clamp 2 can be made close to zero, greatly reduce the waste of blood.Described tremulous pulse needle base 1 is 8cm～9cm with the described distance rushing side pipe 3 in advance, further reduces the waste of blood.The length of described tremulous pulse supervisor 4 is 180cm～220cm.
Further, described rush side pipe 3 end connecting integration transfusion device in advance, medicinal liquid rescue patient life can be inputted in time when there is suddenly change of illness state during patient is in hemodialysis, providing simple and convenient operating condition for complete closed blood back better.
Further, described arterial blood pressure monitoring side pipe 5 and described venous pressure monitoring side pipe 16 all include the pressure transducer for detecting arterial pressure and vein pressure and the alarm device being connected with described pressure transducer.Arterial pressure and vein pressure can be understood in real time, better control over dialysis procedure.When pressure exceedes setting value, namely alarm device performs relevant action.
Further, described tremulous pulse supervisor 4, described vein supervisor 10, described blood pump pipe 6, the connecting tube between described tremulous pulse kettle 7 and described dialyser 8, the connecting tube between described dialyser 8 and described venous chambers 9 and described vein supervisor 10 are polyethylene tube；Described alarm device includes sound prompt device and alarm lamp.This material is conveniently easy to get, it is possible to decrease use cost.Described alarm device points out medical personnel when pressure exceedes setting value in the way of voice and flicker, to carry out associative operation.
Further, tremulous pulse Sampling Interface 13 and interface 14 are also included；Described tremulous pulse Sampling Interface 13 is located on described tremulous pulse supervisor 4, and rushes in advance between side pipe 3 and described arterial blood pressure monitoring side pipe 5 described；Described vein Sampling Interface 14 is located on described vein supervisor 10, and between described venous chambers 9 and described vein needle base 12；The purposes such as the blood sample gathered can perform an analysis, chemical examination, reduce patient's puncture blood collecting to be best understood from patient health situation, safeguard that it is healthy better.
Further, also including the anticoagulant side pipe 15 containing heparin or hirudin, described anticoagulant side pipe 15 is located on the pipeline between described blood pump pipe 6 and described tremulous pulse kettle 7, can be effectively prevented blood coagulation.
The operation principle of the technical program is as follows:
Break through journey in advance: the described union joint rushing side pipe 3 in advance carries pipe to be connected with normal saline, open blood pump pipe 6 (100ml/min), it is slowly injected into described tremulous pulse supervisor 4, tremulous pulse kettle 7, dialyser 8, venous chambers 9, vein supervisor 10 by disposable for normal saline, until the air in each pipeline drains, pre-punch can start dialysis procedure after becoming.
The side pipe that rushes in advance of the prior art is arranged on arterial blood pressure monitoring side pipe 5 place of the technical program, rush direction in advance for from arterial end to vein end, therefore to rush in advance between side pipe and described tremulous pulse needle base 1 part described tremulous pulse supervisor 4 to rush effect in advance bad, the technical program is rushed after side pipe 3 is arranged on described tremulous pulse needle base 1 by described in advance, described tremulous pulse can be responsible for 4 and carry out good pre-punching, it is greatly improved and rushes effect in advance, and improve efficiency.
Blood back process: rush side pipe 3 described in prior art in advance and be positioned at the position of arterial blood pressure monitoring side pipe described in the technical program 5, after the technical program improvement, the described side pipe 3 that rushes in advance is near described tremulous pulse needle base 1, when adopting airtight blood back, folder closes described tremulous pulse supervisor 4, stop drawing blood from patient body, then turn on the described side pipe 3 that rushes in advance and connect normal saline blood back, the distance rushing side pipe and described tremulous pulse needle base 1 in advance being responsible on 4 before described blood pump pipe 6 because of tremulous pulse described in prior art is longer, so that described tremulous pulse supervisor 4 has more blood to be detained, when described dialyser 8 after blood pump (being located on described blood pump pipe 6) and the blood recovery in described vein supervisor 10 are clean, blood pump quits work, opening described tremulous pulse supervisor's safety clamp 2 adopts atmospheric pressure blood back to enter in the patient by the blood recovery being detained on described tremulous pulse supervisor 4, the time of airtight blood back is up to 5mins～8mins, it is easily caused the blood coagulation in described tremulous pulse supervisor 4 or forms thrombosis, cause the blood loss in described tremulous pulse supervisor 4.
The technical program is rushed after side pipe 3 moves to described tremulous pulse needle base 1 by described in advance, can reduce blood and be detained, can whole blood in recirculation line only with airtight blood back, it is not necessary to atmospheric pressure blood back, not ingress of air, reduces potential safety hazard.
The foregoing is only embodiment of the present utility model; not thereby scope of patent protection of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; directly or indirectly it is used in other relevant technical field, all in like manner includes in scope of patent protection of the present utility model.
