Abstract
A blood inlet-outlet branch vessel intersected type artificial heart system in the field of biomedical engineering comprises a blood inlet vessel, a one-way valve, a trachea, an artificial heart, a blood outlet vessel, blood inlet branch vessels, blood outlet branch vessels and a heart valve, wherein the heart valve partitions an artificial heart air cavity and a blood cavity, an outlet of a first blood inlet branch vessel and an inlet of a second blood outlet branch vessel are communicated with the right side of the blood cavity, and an inlet of the first blood outlet branch vessel and an outlet of a second blood inlet branch vessel are communicated with the left side of the blood cavity. The blood inlet-outlet branch vessel intersected type artificial heart system can enable blood in the blood cavity to flow smoothly and enable the blood not to form a vortex and accordingly decreases thrombus. The blood inlet-outlet branch vessel intersected type artificial heart system is reasonable in design and simple in structure and is suitable for a patient with thrombus sensitivity.
Description
Technical field
What the present invention relates to is a kind of artificial heart system of biomedical engineering field, particularly a kind of turnover blood arm staggered form artificial heart system.
Background technology
Artificial heart is namely used the partially or completely pump blood function of alternative heart of bio-mechanical means, keeps the blood circulation of whole body.Comprise ventricle auxiliary blood pump and total artificial heart by the function division.Artificial heart is transplanted to 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 the equipment that replaces 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 owing to 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 satisfy 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 earn a bare living 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 the artificial heart; When the blood flow in the artificial heart produced whirlpool, erythrocyte was subjected to shear downright bad in whirlpool easily and forms thrombosis.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of turnover blood arm staggered form artificial heart system is provided, can effectively prevent the formation of tampon.
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 advances the blood arm, second advances the blood arm, second adaptor, the first hemorrhage arm, the second hemorrhage arm and heart thin film, check valve is installed in in the blood vessel, the heart thin film is installed in the 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 first adaptor is connected with the outlet of advancing blood vessel, the outlet of first adaptor respectively with first import of advancing the blood arm, second import of advancing the blood arm is connected, first advances the outlet of blood arm, the import of the second hemorrhage arm all is connected with the right side of blood chamber, the outlet of second adaptor is connected with the import that goes out blood vessel, the import of 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, second outlet of advancing the blood arm all is connected with the left side of blood chamber, first outlet of advancing the blood arm is positioned at the top of the second hemorrhage arm import, the import of the first hemorrhage arm is positioned at second and enters the top of blood arm outlet, first advances the blood arm, second advances the blood arm, the first hemorrhage arm, the internal diameter of the second hemorrhage arm all equates, first to advance the length of blood arm identical with the length of the first hemorrhage arm, and second to advance the length of blood arm identical with the length of the second hemorrhage arm.
Further, first enters the left and right sides that blood arm and the first hemorrhage arm are symmetrically distributed in artificial heart in the present invention, and second enters the left and right sides that blood arm and the second hemorrhage arm are symmetrically distributed in 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 the blood vessel, and blood advances blood arm and second through first and advances blood arm inflow blood chamber; When the pressure in the air chamber was big, the heart thin film was upspring downwards, and the volume of blood chamber diminishes, pressure becomes big, advances the closed check valve in the blood vessel, and blood flows out blood chamber through the first hemorrhage arm and the second hemorrhage arm.Because second advances blood arm and the second hemorrhage arm arranged crosswise, the whirlpool in the blood chamber will be fewer, thereby can effectively avoid forming in blood chamber thrombosis.
Compared with prior art, the present invention has following beneficial effect: the present invention makes the blood flow in the blood chamber reduce the generation whirlpool as far as possible, thereby can effectively avoid forming thrombosis in blood chamber by increasing the number of advancing blood arm and hemorrhage arm; The present invention is reasonable in design, and is simple in structure, has wider application prospect.
