Description
Technical field
What the present invention relates to is a kind of artificial heart system, particularly a kind of artificial heart system with blood pressure regulating mechanism of biomedical engineering field.
Background technology
Artificial heart, namely partially or completely substitutes the pump blood function of heart by bio-mechanical means, maintain the blood circulation of whole body.Divide by function and comprise ventricle auxiliary blood pump and total artificial heart.Artificial heart is transplanted as a kind of means for the treatment of heart failure, is the effective replacement scheme of cardiac transplantation.Total artificial heart is a kind of for replacing the equipment of two chambers in heart bottom.These two replaced chambers are called as " ventricle ".If a sufferer causes two ventricles all cannot play function again because heart failure reaches an advanced stage, just this equipment may be used.Heart failure refers to that heart causes the enough blood of unable conveying to meet the needs of health owing to suffering damage or weaken." late period " refers to that necessarily very serious degree has been arrived in this heart failure, to such an extent as to every other treatment except heart transplantation all cannot onset.In both cases, patient may need total artificial heart: patient may need total artificial heart to sustain life to instruct the heart that can obtain transplanting; Do not possess the qualification of heart transplantation, but to the heart failure late period of two ventricles loss of function gradually; The atrium of total artificial heart and patient connects.Artificial heart technology is a kind of FA biomedical technology, and along with the increase gradually of modern society heart patient, artificial heart technology will have boundless application prospect.
Through finding the retrieval of prior art document, China Patent No. 99126700.1, patent name: gas-electricity one formula blood pump, gas-electricity one formula artificial heart, this patented technology provides blood pump simplification, artificial heart miniaturization scheme, but it can not effectively regulate artificial heart to go out the hemorrhage pressure of blood vessel, easily causes the fluctuation of blood pressure of patient larger.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, provide a kind of artificial heart system with blood pressure regulating mechanism, the hemorrhage pressure of blood vessel can be gone out by effectively anti-adjustment artificial heart.
The present invention is achieved through the following technical solutions, the present invention includes into blood vessel, check valve, trachea, artificial heart, go out blood vessel, first adaptor, first enters blood arm, second enters blood arm, second adaptor, first hemorrhage arm, second hemorrhage arm, cardiac valves, connection tube, 3rd enters blood arm, cavity volume, moving body, elastomeric element, check valve is arranged on in blood vessel, cardiac valves to be arranged in artificial heart and artificial heart is divided into air chamber and blood chamber two parts, air chamber is positioned at the top of artificial heart, one end of trachea is connected with air chamber, the import of the first adaptor is connected with the outlet of entering blood vessel, and the import of blood arm is entered in the outlet of the first adaptor respectively with first, second import of entering blood arm is connected, the 3rd outlet of entering blood arm, second outlet of entering blood arm is all connected with the right side of blood chamber, and the outlet of the second adaptor is connected with the import going out blood vessel, the import of the second adaptor outlet of hemorrhage arm with first respectively, the outlet of the second hemorrhage arm is connected, the import of the first hemorrhage arm, the import of the second hemorrhage arm is all connected with the left side of blood chamber, 3rd outlet of entering blood arm is positioned at the top that second enters blood branch outlet, the import of the first hemorrhage arm is positioned at the top of the second hemorrhage arm import, the import of connection tube with enter blood vessel and be connected and the upstream being positioned at check valve, the outlet of connection tube is connected with the left side wall of cavity volume, the lower wall of the first outlet and cavity volume of entering blood arm is connected, the upper side wall of the 3rd import and cavity volume of entering blood arm is connected, moving body to be arranged in cavity volume and to seal with the internal face of cavity volume and contacts, and the right wall of moving body is connected with the right wall of cavity volume by elastomeric element.
Further, in the present invention first enter blood arm, second enter blood arm, the 3rd enter blood arm, the first hemorrhage arm, the second hemorrhage arm internal diameter all identical, the cross section of cavity volume is rectangle, and elastomeric element is spring.
In work process of the present invention, trachea is connected with source of the gas, when the pressure in air chamber is less, cardiac valves pops up, the volume of blood chamber becomes large, pressure diminishes, enter the one-way valve opens in blood vessel, blood through first enter blood arm, second enter blood arm and the 3rd enter blood arm flow into blood chamber; When the pressure in air chamber is larger, cardiac valves is upspring downwards, and the volume of blood chamber diminishes, pressure becomes large, enters the closed check valve in blood vessel, and blood flows out blood chamber through the first hemorrhage arm and the second hemorrhage arm.When entering intravascular pressure and being larger, the volume cavity pressure on the left of moving body is also comparatively large, and moving body moves right and elasticity of compression parts, flow through the oligemia that the 3rd enters blood arm, thus the hemorrhage pressure of using blood vessel diminishes; When entering intravascular pressure and being less, the volume cavity pressure on the left of moving body is also less, and under the effect of elastomeric element, moving body is moved to the left, and flow through the 3rd blood volume entering blood arm and increase, thus the hemorrhage pressure recover of using blood vessel is normal.
Compared with prior art, the present invention has following beneficial effect: the present invention enters the blood flow of blood chamber by changing, and can realize out the self regulation of angiorrbagia pressure, thus uses blood pressure power and also can remain stable when entering blood pressure power and being higher; The present invention is reasonable in design, and structure is simple, has wider application prospect.
