Abstract
A percutaneous heart-assist device includes a blood pump, a blood inlet tube and a blood outlet tube with different length are respectively connected with the inlet orifice and the outlet orifice of the blood pump. Implanted in the body, the device decreases the preload of the left and the right heart chamber without any damage on the structure and function of the heart, makes the over-dilatated heart chamber reduce gradually, thereby, the function of the heart is recovered or back to normal. The purpose is to provide a low price percutaneous heart-assist device which is helpful to blood cycle by decreasing the preload of the left and right heart chamber.
Description
Technical field
This utility model relates to a kind of transfering human medium's device, relates in particular to a kind of sanguimotor percutaneous heart-assist device that helps.
Background technology
The artificial heart that uses need carry out open chest surgery at present, heart and health to the patient all have certain damage, complication such as operation back is easily infected, lost blood, renal failure, be difficult to reach depleted heart is returned near normal cardiac function, operative effect is not very desirable, and surgery cost is very high.
The utility model content
The purpose of this utility model provides a kind of preload that reduces left and right ventricle, and medical expense is low helps sanguimotor percutaneous heart-assist device.
For achieving the above object, this utility model provides a kind of percutaneous heart-assist device, comprises blood pump, and the inlet opening of described blood pump and liquid outlet are connected to unequal feed tube of length and drain pipe respectively.
Percutaneous heart-assist device of the present utility model, wherein said feed tube and drain pipe are parallel with one another, are fixed with annular air bag on the lateral wall of feed tube inlet end, and air bag is connected with trachea, and trachea is in parallel with described feed tube and drain pipe.
Percutaneous heart-assist device of the present utility model, the diameter of wherein said feed tube and drain pipe are 1-5mm.
Percutaneous heart-assist device of the present utility model, it comprises blood pump, the inlet opening of described blood pump and liquid outlet are connected to unequal feed tube of length and drain pipe respectively, with its implant into body, have following advantage:
1. it can reduce the preload of left and right ventricles chamber under the situation of not damaging cardiac structure and function, makes to be in the transition expanding ventricular cavity and to dwindle gradually, thereby cardiac function is recovered or near normal.
Wicresoft, only skin and blood vessel wall are had the minor injury.
3. postoperative patient recovers fast, and patient is acceptant.
4. but the short time uses, and also can adopt embedded type (imbedding subcutaneous) life-time service.
5. medical expense is low, and the price of the artificial heart that uses is more than 900,000 yuans at present, and the expense of percutaneous heart-assist device of the present utility model is several ten thousand yuans.
6. can avoid because of heart transplantation, use all complication that artificial heart brought, and be that treatment expanding heart disease, heart failure have been opened up new approach.
Through percutaneous heart-assist device of the present utility model to heart, kidney topical, have that dosage is few, curative effect is high, reduce the effect of drug side effect
Below in conjunction with accompanying drawing percutaneous heart-assist device of the present utility model is described further.
Description of drawings
Fig. 1 is the structural representation of percutaneous heart-assist device of the present utility model.
The specific embodiment
As seen from Figure 1, percutaneous heart-assist device of the present utility model comprises blood pump 1, and the inlet opening of described blood pump 1 and liquid outlet are connected to feed tube 2 and drain pipe 3 respectively, and feed tube 2 and drain pipe 3 are parallel with one another, and its length is unequal.Be fixed with annular air bag 4 on the lateral wall of described feed tube 2 inlet ends, air bag 4 is connected with trachea 5, and trachea 5 is in parallel with described feed tube 2 and drain pipe 3.After heaving, annular air-pocket 4 can make the inlet end of feed tube 2 leave the sidewall tissue of human organ, the inlet end that prevents feed tube 2 is blocked, influence the normal operation of percutaneous heart-assist device, the diameter of described feed tube 2 and drain pipe 3 is 2mm, also can be 1-5mm, described blood pump 1 is fixed on human external, or it is subcutaneous to imbed the subcutaneous or right groin of left groin of human body, also can be fixed on other object.
Percutaneous heart-assist device of the present utility model in use, feed tube 2 and drain pipe 3 can be inserted human body together with trachea 5 along femoral artery, blood pump 1 is fixed near the human body in insertion point, and wherein feed tube 2 is inserted into left ventricle, and drain pipe 3 is inserted in renal artery or the aortic arch; Or feed tube 2 and drain pipe 3 inserted human body together with trachea 5 along femoral vein, and blood pump 1 is fixed near the insertion point the human body, and wherein feed tube 2 is inserted into right ventricle, and drain pipe 3 is inserted into pulmonary artery; Or feed tube 2 and drain pipe 3 inserted human body along subclavian vein, and blood pump 1 is fixed near the insertion point the human body, and wherein feed tube 2 is inserted into right ventricle, and drain pipe 3 is inserted into pulmonary artery; Or feed tube 2 and drain pipe 3 inserted human body together with trachea 5 along scratching tremulous pulse or brachial artery, and blood pump 1 is fixed near the insertion point the human body, and wherein feed tube 2 is inserted into left ventricle, and drain pipe 3 is inserted in the aortic arch.After in feed tube 2 is inserted into left ventricle or right ventricle, again by 5 pairs of air bag 4 injecting gas of trachea, make air bag 4 heave, trachea 5 is sealed from the end again, start blood pump 1 then, blood pump 1 will be extracted blood out through feed tube 2 in left ventricle or right ventricle, again through drain pipe 3 with the position of blood transport to drain pipe 3 port places, thereby reduce the preload of left and right ventricle, make to be in the transition expanding ventricular cavity and to dwindle gradually, cardiac function is recovered or near normal.
Embodiment recited above is described preferred implementation of the present utility model, is not that design of the present utility model and scope are limited.The content that this utility model is asked for protection all is documented in claims.
