The content of utility model:
The purpose of this utility model is to propose a kind of novel two perfusion devices sequential device technique scheme in parallel, solves in prior art and has the defect existing in multiple tank series operation.
The content of the two perfusion devices of this utility model sequential device in parallel is:
Comprise at least plural blood perfusion device, plural blood perfusion device is connected in parallel in extracorporeal circulation blood circuit, and a clamp is respectively set on the shunting bloody path in the bloody path of upstream, the opening or closing of this bloody path of clamp control; At upstream clamp, to the upper outside reflux pump bloody path that connects of the bloody path between perfusion device, reflux pump bloody path other end UNICOM orders about the normal saline that blood backflow is used.
A clamp can also be also respectively set on branch's bloody path in perfusion device downstream.
The two perfusion devices of this utility model sequential device in parallel can be realized automatic control.The automatic control program step realizing is:
Controlling Node configuration signals collecting in each operation of bloody path is connected with instruction accepting device and with automatic control system;
The running of automatic control program is pre-conditioned according to operator:
Start at first pre-stroke order, equipment automatically performs normal saline solution and anticoagulant; Reach pre-conditioned and system monitoring in bloody path during without air bubble, break through in advance journey and finish;
Equipment, according to pre-conditioned startup treatment procedure, is opened A perfusion device clamp A1, A2, closes B perfusion device clamp B1, B2, the operation of A perfusion device; Blood, in the time that the processing of A perfusion device reaches pre-conditioned, is closed clamp A1, and A perfusion device is out of service; Open B perfusion device clamp B1, B2, the operation of B perfusion device simultaneously; Start reflux pump, normal saline solution orders about blood backflow human body in A tank; When reflux pump reaches Preset Time, automatically stop, clamp A2 closes; Blood, in the time that the processing of B perfusion device reaches pre-conditioned, is closed clamp B1, starts reflux pump, and normal saline solution orders about blood backflow human body in B tank;
According to pre-conditioned, can release on the blood perfusion device A of operation or B position, change the outfit blood perfusion device C, D new, that process through pre-punching changing, clamp A1, A2 or B1, B2 are opened or close in circulation; Treatment procedure continuity.
Embodiment of the present utility model and embodiment
Embodiment of the present utility model is as shown in drawings:
Accompanying drawing is the schematic diagram of technical solutions of the utility model, only indicates the most basic framework of this utility model device in figure.
Numeral in figure and alphabetical label represent respectively:
1, upstream (tremulous pulse) bloody path, 2, arterial pressure interface, 3a, 3b blood pump, 4, crimping mouth before filter, 5, anticoagulant pump, 6, backflow bloody path, 7, normal saline/displacement liquid, 8, electronic scale, 9, downstream (vein) bloody path, 10, venous pressure interface, 11, air monitor, 12, vein clamp; A, blood perfusion device, B, blood perfusion device, bloody path clamp is divided in A1, B1, upstream, and bloody path clamp is divided in A2, B2, downstream.
Accompanying drawing illustrates this utility model device in conjunction with the embodiments:
The present embodiment is A, two blood perfusion device devices arranged side by side of B.The path of blood systemic circulation is: upstream (tremulous pulse) bloody path 1 is drawn peripheral blood to this device bloody path from human body artery, introduce respectively A, two blood perfusion devices of B through branch's bloody path, after flowing out perfusion device, merge into downstream (vein) bloody path 9 by branch's bloody path, be back to human body.The arterial pressure interface 2 of connecting in the bloody path of upstream (tremulous pulse) detects arteriotony, blood pump 3a provides hemodynamic for extracorporeal circulation blood circuit, before filter, crimping mouth 4 provides blood pressure data detection signal, anticoagulant pump 5 is to the anticoagulant of annotating in bloody path, on A perfusion device, bloody path A1 is divided in the upstream arranging in downstream branch bloody path, downstream branch bloody path A2, on B perfusion device, bloody path clamp B1 is divided in the upstream arranging in downstream branch bloody path, downstream branch bloody path clamp B2, the order venous pressure interface 10 of connecting in downstream (vein) bloody path 9, air monitor 11, with vein clamp 12, backflow bloody path 6 is set between upstream branch bloody path clamp and blood perfusion device, backflow blood pump 3b is set in backflow bloody path and provides power for backflow blood, backflow bloody path 6 outer end UNICOM normal saline/displacement liquids 7, can be placed in normal saline/displacement liquid on electronic scale 8, metering capacity of returns.
In the present embodiment accompanying drawing, 6 of backflow bloody paths indicate and have connected a blood perfusion device, in reality, can all be connected in identical position with every perfusion device, play identical backflow blood effect.
Running of the present utility model and automatic control program arrange as follows:
While just bringing into operation, divide and break through in advance journey and therapeutic process.This is the most basic running of this utility model and automatic control program.
Breaking through in advance journey comprises:
Operator sets and rushes in advance normal saline and anticoagulant total amount, and equipment automatically performs pre-punching according to the automatic control program of setting, by whether having bubble in air monitor monitoring pipeline.After reaching anticoagulant total amount and monitoring in pipeline without air bubble, break through in advance journey and finish.
Therapeutic process comprises:
, before begin treatment, operator sets the blood treatment amount of A tank; The course for the treatment of, while beginning, clamp A1, A2 opened, and clamp B1, B2 close, and A tank operation: start blood pump 3a, blood flow is crossed A perfusion device reaches after the default blood treatment amount of A tank, and clamp A1 closes, and A tank is out of service; Open clamp B1, B2, blood flow is through B perfusion device, and B tank brings into operation; Start reflux pump 3b simultaneously, open clamp A2, normal saline solution 7 enters A perfusion device via backflow bloody path 6, and orders about A perfusion device blood backflow to downstream bloody path 9, after be back to human body; A tank blood backflow is complete, closes A2 clamp; B tank continues processing blood when imposing a condition, blood pump 3a closes, clamp B1 closes, the backflow bloody path 6 that connects B tank upstream branch bloody path starts, succinct for drawing, does not indicate this section of backflow bloody path, the enlightenment that is connected according to A tank in figure with backflow bloody path 6 in figure, can easily understand the connected mode here, normal saline solution 7 orders about blood backflow in tank to human body through B tanks, downstream bloody path 9.When whole blood backflows are to human body, close clamp 12, treat complete.
