Description
Technical field
The utility model is related to heart assistance cycle art, and in particular to a kind of external auxiliary circulation system.
Background technology
With developing rapidly for department of cardiac surgery, the wherein hurried increase of quantity of cardiac operation under direct vision, significant heart disease patient
Also proportional rising.According to statistics, there is serious Low cardiac output syndrome in the patient that 1% is there are about after cardiac operation under direct vision, although
Can not still be taken off using various vasoactive agents and IABP (Intra-AortiCBalloonPump, IABP)
In vitro outer circulation to withdraw extracorporal circulatory system, promotes myocardial function to recover, it is necessary to assist carries out heart assistance.
During Acute Myocardial Infarction Complicated with Cardiogenic Shock, even if drug application even IABP, its death rate is still up to 60%-80%.Make
With assist then this kind of patient's haemodynamics may be stabilized, so as to be performed the operation, larger existence is obtained
Chance.Heart transplant is worldwide rapid at present to be carried out extensively, and operation quantity substantially increases, and survival rate is also improved constantly,
Make one for the treatment of maximally effective means of endstage cardiac insufficiency.However, being that heart transplant operation is opened extensively for heart deficiency
The biggest obstacle of exhibition.Heart assistance is carried out using assist, can be to wait the patient for the heart to break away from heart failure.From
And the acquisition more sufficient time wins and suitably supplies the heart.Additionally, it is current solution for heart deficiency to be circulated using heart assistance
One of important means.In recent years, heart-assist device is being updated and is being subject to perfect, new product and continues to bring out, many products
The own commercialization of product, it is functional, use safety.No matter heart assistance is circulated as remedy measures or the mistake as heart transplant
Cross and support that all oneself achieves significant progress, enables patient's symptom of heart failure to be obviously improved, quality of life is significantly improved,
Many patients can enjoy normal life for being gone home between heart stage using after heart assistance waiting, it might even be possible to resume work.
China Patent Publication No. CN200810204114.2 discloses a kind of pulsation type double-haematodocha heart auxiliary circulation device, leads to
Crossing hydraulic way makes two haematodocha shrink each other with diastole so as to realize the circulation of blood, due to normal adult heartbeat per minute
At 60-100 times or so, hydraulic way is difficult to the switching within such short time；This pair of capsule construction profile is different from truly
Heart shape, even if Volume Changes are identical when shrinking with diastole every time is also difficult to ensure that the CBF for passing through is the same；Medical matters people
Member is operated by interactive interface, and the different decrements of blood pump, compression ratio and beating amount, this mode are set for different patients
The synchronous circulating with patient can not be realized, thus true heart function can not be simulated.External membrane lung clinical practice device can at present
Heart assistance circulation is substituted, but the device is non-pulsation, is misfitted with cardiovascular rhythmic pulsation, has run counter to human body certainly
The physilogical characteristics of body.
