Abstract
An artificial heart system with double blood outgoing branch tubes in the field of biomedical engineering comprises a blood incoming tube, a one-way valve, an air tube, an artificial heart, a blood outgoing tube, blood incoming branch tubes, blood outgoing branch tubes and a heart membrane. The heart membrane divides the artificial heart into an air cavity and a blood cavity. An outlet of every blood incoming branch tube is communicated with the right side of the blood cavity. An inlet of every blood outgoing branch tube is communicated with the left side of the blood cavity. The inner diameter of the first blood incoming branch tube is equal to that of the first blood outgoing branch tube, the inner diameter of the second blood incoming branch tube is equal to the inner diameter of the second blood outgoing branch tube, and the inner diameter of the first blood incoming branch tube is larger than that of the second blood incoming branch tube. The artificial heart system allows blood in the blood cavity to flow more smoothly, with rarely occurring vortexes, thus less thrombi occur. The artificial heart system is reasonable in design, simple in structure and applicable to patients who are sensitive to thrombi.
Description
Technical field
What the present invention relates to is a kind of artificial heart system of biomedical engineering field, particularly a kind of system of artificial heart with two hemorrhage arms.
Background technology
Artificial heart, namely partially or completely substitute the pump blood function of heart with the bio-mechanical means, keeps the blood circulation of whole body.Divide and comprise ventricle auxiliary blood pump and total artificial heart by function.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 equipment for replacing two chambers in heart bottom.These two replaced chambers are called as " ventricle "., if a sufferer causes two ventricles all can't bring into play function again because heart failure reaches an advanced stage, just may use this equipment.Heart failure refers to that heart causes the enough blood of unable conveying to meet the needs of health owing to suffering damage or weakening." late period " refers to that this heart failure arrived necessarily very serious degree, to such an extent as to every other treatment except heart transplantation all can't onset.In both cases, the patient may need total artificial heart: the patient may need total artificial heart to sustain life to instruct the heart that can obtain to transplant; Do not possess the qualification of heart transplantation, but to two ventricles heart failure late period of loss of function gradually; Total artificial heart and patient's atrium joins.The artificial heart technology is a kind of FA biomedical technology, and along with modern society heart patient's increase gradually, the artificial heart technology will have boundless application prospect.
Find through the retrieval to the 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 avoid the formation problem of thrombosis in artificial heart; When the blood flow in artificial heart produced whirlpool, erythrocyte easily was subjected to shear downright bad and forms thrombosis in whirlpool.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of system of artificial heart with two hemorrhage arms is provided, can effectively prevent the formation of tampon.
the present invention is achieved through the following technical solutions, the present invention includes into the blood part, artificial heart part and hemorrhage part, advance the blood part by advancing blood vessel, check valve, the first adaptor, first advances blood arm and second advances blood arm formation, the artificial heart part is by the heart thin film, air chamber, blood chamber and trachea form, hemorrhage part is by the first hemorrhage arm, the second hemorrhage arm, the second adaptor and go out blood vessel and form, check valve is arranged in blood vessel, the heart thin film is arranged in artificial heart and artificial heart and 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 advancing blood vessel, the outlet of the first adaptor respectively with the first import of advancing the blood arm, the second import of advancing the blood arm is connected, first advances the outlet of blood arm, the second outlet of advancing the blood arm all is connected with the right side of blood chamber, the outlet of the second adaptor is connected with the import that goes out blood vessel, the import of the second adaptor respectively with the outlet of the first hemorrhage arm, the outlet of the second hemorrhage arm is connected, the import of the first hemorrhage arm, the import of the second hemorrhage arm all is connected with the left side of blood chamber, the first outlet of advancing the blood arm is positioned at second and enters the top of blood arm outlet, the import of the first hemorrhage arm is positioned at the top of the second hemorrhage arm import, first advances the blood arm, second advances the blood arm, the first hemorrhage arm, the identical length of the second hemorrhage arm etc., first to advance the internal diameter of blood arm identical with the internal diameter of the first hemorrhage arm, second to advance the internal diameter of blood arm identical with the internal diameter of the second hemorrhage arm, the first internal diameter that advances the blood arm is greater than the second internal diameter that advances the blood arm.
Further, first advances blood arm and the first hemorrhage arm and is symmetrically distributed in the left and right sides of artificial heart in the present invention, and second advances blood arm and the second hemorrhage arm is symmetrically distributed in the left and right sides of artificial heart.
In work process of the present invention, trachea is connected with source of the gas, and the pressure in air chamber hour, the heart thin film pops up, the volume of blood chamber becomes greatly, pressure diminishes, and advances the one-way valve opens in blood vessel, and blood advances blood arm and second through first and advances blood arm inflow blood chamber; When the pressure in air chamber was larger, the heart thin film was upspring downwards, and the volume of blood chamber diminishes, pressure becomes large, advances the closed check valve in blood vessel, and blood flows out blood chamber through the first hemorrhage arm and the second hemorrhage arm.Greater than the second internal diameter that advances the blood arm, flowing through like this first blood flow that advances the blood arm will be some more due to the first internal diameter that advances the blood arm, and the whirlpool in blood chamber will be fewer, thereby can effectively avoid forming thrombosis in blood chamber.
Compared with prior art, the present invention has following beneficial effect: the present invention, by increasing into the number of blood arm and hemorrhage arm, makes the blood flow in blood chamber reduce and produce whirlpool as far as possible, thereby can effectively avoid forming thrombosis in blood chamber; The present invention is reasonable in design, and is simple in structure, has wider application prospect.
