Description
Technical field
The utility model is related to artificial oxygen therapy field, and in particular to a kind of auxiliary circulation two-way arterial duct, control system
System.
Background technology
ECMO (extracorporeal membrane oxygenation, ECMO), abbreviation membrane lung is one
Cardiopulmonary Bypass when coming from cardiac surgery operation is planted, essence is a kind of heart-lung machine of improvement, be the critically ill patient's life of rescue
The new technology of life.ECMO most crucial equipment is membrane oxygenator and blood pump, plays artificial lung and the heart respectively.ECMO is main
For serious respiratory disorder, circulatory diseases and CPR.It is noted that ECMO does not treat protopathy in itself, only to other
The offer valuable time that plays a role is provided, therefore curative effect and kinds of Diseases are closely related.
ECMO progress is mainly reflected in two aspects：(1) application expand, be progressively expanded to from neonate children and into
People, is related to disease and is also continuously increased.(2) technical equipment is improved, and membrane oxygenator, pump and pipeline are ECMO key components.
Kolobow silica gel membrane oxygenator is more than 30 years in clinical practice, compared with having side opening doughnut membrane oxygenator, with performance
Long advantage is asked when reliably, using, but pellosil has larger affinity to blood platelet, easily causes decrease of platelet and film oxygen is closed
The increase of device resistance.New to have the advantages that resistance is low without side opening doughnut membrane oxygenator, treated fiber surface has anti-
Thrombotic effect.Past routinely uses occlusion pump, and now frequently with the centrifugal pump that can be used for a long time, the latter can produce more
Big motive force.These improvement improve curative effect, after adopting new technology, and draw that blood channel wall is thinner, and internal diameter is bigger, are conducive to increase
Draw blood volume.
ECMO drive manners include VV paths and VA paths, and the former is mainly used in external Breathing Suppotion, and the latter is used to breathe
Circulatory support.With the application of pulmonary surfactant, nitric oxide and high-frequency ventilation technology, for answering that respiratory failure is supported
With gradually decreasing, and gradually increase as the support means of heart failure, i.e. the ECMO of VA patterns supports system in clinic
Using increasingly extensive, and tend to minimally invasiveization.Intubation way conventional VA-ECMO has two kinds：Surrounding intubation (stock artery-vein intubation,
Jugular vein-arteria carotis communis intubation) and central cannula (atrium dextrum-aorta ascendens intubation), wherein minimally invasive method arterial intubation is optional
Select arteria carotis or femoral artery.Due to arteria carotis intubation risk it is relatively large, be clinically expert at present minimally invasive intervention diagnosis and therapy when be inclined to
Pipe is put in selection femoral artery.But due to current ECMO femoral arteriography be always to conduit, it is relatively short, after extracorporal circulatory system
Blood flow be difficult to reach aorta ascendens, be only capable of ensureing lower extremity blood flow, it is difficult to ensure coronary artery and arch of aorta bifurcated artery
Blood oxygen supply, so that coronary artery, upper limbs and brain tissue occur irrigates insufficient, and the relatively excessive phenomenon of lower limb oxygen blood, cause
" north and south syndrome (north-south syndrome) "；On the other hand, because current femoral arteriography is always to conduit, i.e.,
The blood flow after extracorporal circulatory system is reached aorta ascendens, because through femoral artery put pipe rear tube outlet it is straight to blood flow direction with
Forward blood flow liquidates sustainer, influences opening and closing and the left ventricular function of aorta petal, reduce further sustainer forward
The blood supply efficiency of blood flow.
Utility model content

Syndrome ".
Inverse export in the side sets raised on blood exit port inwall, vertical by the raised guiding blood flow direction
Down.
By the detection to oxygen concentration in coronary artery, upper limbs, brain tissue and lower limb blood oxygen, in the S-shaped passage side
Or both sides are arranged at intervals the inverse outlet in multiple sides.
It is a kind of that containing control system of the auxiliary circulation with two-way arterial duct, the control system includes arterial duct,
Blood transfusion tube, butterfly valve, flowmeter, controller, control panel；The arterial duct body blood inlet end passes through flexible pipe and blood transfusion tube
Connection, it is upper and be connected with the controller that the flowmeter, butterfly valve are successively set on blood transfusion tube side, controller with it is described
Control panel is connected.
By setting the CBF being passed through in arterial duct body on the control panel, controller control butterfly valve opens one jiao
Degree, while result by the CBF of blood transfusion tube and is fed back to controller by flowmeter detection, controller according to feedback result again
Butterfly valve opening angle is adjusted, until the flow that flowmeter is detected is equal to setting flow value.
A kind of control method using the control system, comprises the following steps：
1), the arterial duct body is inserted into artery, and carries out the back works such as hemostasis sterilization；
2) CBF being passed through in arterial duct body, is set on the control panel as a setting value；
3), the control panel transfers signals to controller, and controller control butterfly valve is opened and to arterial duct body
Interior conveying blood, while flowmeter detects the CBF by blood transfusion tube and numerical result is fed back into controller, works as CBF
During more than setting value, controller, which is sent, makes butterfly valve angle open reduction order, and when CBF is less than setting value, controller is sent
Butterfly valve angle is set to open increase order, until the CBF that flowmeter is detected is equal to setting value.
The beneficial effects of the utility model are：By setting the inverse outlet in side close to knee in S-shaped passage, when blood along
When S-shaped passage flows, a part is from positive outlet outflow, and another part flows out inverse outlet from side, so that the blood after being closed through peroxide
Liquid flows along both direction respectively, not only ensures lower extremity blood flow, moreover it is possible to ensure coronary artery and arch of aorta bifurcated artery
Blood oxygen supply, makes coronary artery, upper limbs, brain tissue and lower limb blood oxygen supply uniform, it is to avoid " north and south syndrome ".
