Abstract
A kind of biomedical engineering field with two enter the artificial heart system of blood arm, comprise into blood vessel, check valve, trachea, artificial heart, go out blood vessel, enter blood arm, hemorrhage arm and cardiac valves, cardiac valves is artificial heart air chamber and blood chamber, the right side of the outlet and blood chamber of entering blood arm is connected, the import of hemorrhage arm is connected with the left side of blood chamber, first to enter the length of blood arm identical with the length of the first hemorrhage arm, second length second length of entering blood arm identical with the length of the second hemorrhage arm entering blood arm is greater than the length that first enters blood arm.The present invention can make the blood flow in blood chamber more smooth, not easily forms whirlpool, thus reduces the formation of thrombosis.The present invention is reasonable in design, and structure is simple, is applicable to the artificial heart system to the comparatively responsive patient of thrombosis.
Description
Technical field
What the present invention relates to is a kind of artificial heart system of biomedical engineering field, particularly a kind of with two enter the artificial heart system of blood arm.
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 effectively can not avoid the formation problem of thrombosis in artificial heart; When the blood flow in artificial heart produces whirlpool, erythrocyte easily forms thrombosis by shearing downright bad in whirlpool.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, provide a kind of with two enter the artificial heart system of blood arm, can the formation of effectively anti-tampon.
The present invention is achieved through the following technical solutions, the present invention includes into blood part, artificial heart part and bleeding sites, enter blood part by entering blood vessel, check valve, first adaptor, first enters blood arm and second enters blood arm formation, artificial heart part is by cardiac valves, air chamber, blood chamber and trachea are formed, bleeding sites is by the first hemorrhage arm, second hemorrhage arm, second adaptor and go out blood vessel form, 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, 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, first outlet of entering blood arm, second outlet of entering blood arm is all connected with the right side of blood chamber, 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, first 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, first enters blood arm, second enters blood arm, first hemorrhage arm, the internal diameter of the second hemorrhage arm is all equal, first to enter the length of blood arm identical with the length of the first hemorrhage arm, second to enter the length of blood arm identical with the length of the second hemorrhage arm, second length entering blood arm is greater than the length that first enters blood 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, when the pressure in air chamber is less, cardiac valves pops up, the volume of blood chamber becomes large, pressure diminishes, and enters the one-way valve opens in blood vessel, and blood enters blood arm and second through first and enters blood arm inflow 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.Because the first length entering blood arm is less than the length that second enters blood arm, flowing through the first blood flow entering blood arm like this will be some more, and the whirlpool in blood chamber will be fewer, thus can effectively avoid forming thrombosis in blood chamber.
Compared with prior art, the present invention has following beneficial effect: the present invention, by increasing the number into blood arm and hemorrhage arm, makes the blood flow in blood chamber reduce as far as possible and produces whirlpool, thus can effectively avoid forming thrombosis in blood chamber; The present invention is reasonable in design, and structure is simple, has wider application prospect.
