Abstract
The utility model disclose a complete implantable heart donkey pump, which comprises a pump body and a drive device, wherein the outer surface of the support ring of the pump body is disposed ethylene cloth which is sewed on the inner wall of the blood vessel, the drive device is provided on the pump body, a permanent magnet provided on the pump body drives the permanent magnet at the principle of homosexual exclusion and heterosexual attraction, an oar fixed on the pump body rotates with the permanent magnet to drive blood flowage. The pump body and the drive device of the utility model are simple in structure, small in volume, which decreases eye winker planted into body. The utility model is low in cost, which reduces medical cost largely. The utility model has the advantage of being jointed without artificial blood vessels; of complete adoption of none contact transferring moment, safety, credibility, convenient and practicality. The utility model has a wide application foreground in heart blood vessels and other correlated field.
Description
Technical field
This utility model relates to the medical treatment device in a kind of implant into body, especially relates to a kind of blood pump of accessory heart work.
Background technology
At present for whole latter stage the heart failure patient treatment be a unusual stubborn problem, the most methods of medical treatment can only mitigation symptoms, can not prolong patient's life.Therefore people have carried out positive exploration at surgical field, have attempted nearly all possibility, and heart transplantation is exactly comparatively successful technology, is accepted extensively by each big heart center, the world over nearly 20 years.Yet the effect of heart transplantation has been subjected to the serious restriction of factors such as permanent immunity inhibition, opportunistic infection, and 5 total annual death rate are up to 40%.In addition, the famine of donor has also limited this broad application, and in China and a lot of other country, heart transplantation only is symbolic technology.Therefore people have to, and difficult pulling out relates on the road of artificial heart.At present, the artificial heart technology has had bigger development, has been used for clinical as membrane pump, sickle pump.Yet big, the complex structure of the volume that has of these blood pumps, implantation heart or endovascular foreign body are too much at present, make the contact surface of foreign body and blood excessive, add all and must connect, thereby increased the destruction of blood, the formation of thrombosis and the probability of infection with long artificial blood vessel.Operation simultaneously all must be created new interface, increase the wound to body on heart and blood vessel.The blood pump drives device that has is external, brings inconvenience and mental pressure etc. to patient.
Summary of the invention
The purpose of this utility model provides a kind ofly to be implanted in heart or the trunk and few foreign, need not artificial blood vessel and connect, adopt non contact transmission moment, blood pump with low cost.
This utility model comprises the pump housing and driving device.On the support ring outer surface of the pump housing, be fixed with woven dacron; Driving device separates with the pump housing, and driving device is composed in series by micro machine and permanent magnet, and is positioned at the pump housing outside.
The pole orientation of the Magnet in the pump housing and the driving device is radially, and the Magnet in the pump housing is corresponding with the magnet positions in the driving device.
Adopted in the scheme of the present utility model in the fixing structure of woven dacron of support ring outer surface, can directly woven dacron be sewn on the blood vessel by performing the operation, and need not to connect with artificial blood vessel.Driving device separates with the pump housing and is positioned at the pump housing outside, does not need in its implantable intravascular, and therefore, pump housing volume is little, and vascular inner body is few, can also realize driving device and pump housing non contact transmission moment simultaneously.Because it is overall structure is simple, therefore with low cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cutaway view of the present utility model.
Specific embodiments
Below in conjunction with accompanying drawing this utility model is described in further detail.
Fig. 1, shown in Figure 2, this utility model mainly are made up of the pump housing and driving device.Support ring (5) outer surface of the pump housing is fixed with woven dacron (2), and driving device is composed in series by micro machine (6) and permanent magnet (3), and driving device separates with the pump housing, and is positioned at the pump housing outside.The pole orientation of Magnet is radially in the pump housing and the driving device, and the Magnet in the pump housing is corresponding with the magnet positions in the driving device.During use, woven dacron (2) is made on blood vessel (1) inwall, driving device is fixing close with the blood vessel that the pump housing is housed (1) outer wall in vivo, make Magnet can produce magnetic action mutually.The micro machine of driving device (6) adopts direct current generator, rechargeable battery can be implanted the subcutaneous of stomach wall, finishes charging work by inductive charging.After starting driving device, micro machine in the driving device (6) drives permanent magnet (3) rotation, permanent magnet in the driving device (3) is by the principle of same-sex attraction opposite sex repulsion, drive the permanent magnet rotation in the pump housing again, the paddle (4) that is fixed on the permanent magnet in the pump housing is rotated thereupon, thereby the blood that promotes in the blood vessel (1) flows forward.
Claims (2)
1, a kind of full-implantation type heart assisting pump comprises the pump housing and driving device, it is characterized in that: be fixed with woven dacron 2 on support ring 5 outer surfaces of the pump housing; Driving device separates with the pump housing, and driving device is composed in series by micro machine 6 and permanent magnet 3, and is positioned at the pump housing outside.
2, a kind of full-implantation type heart assisting pump according to claim 1, it is characterized in that: the pole orientation of the permanent magnet in the pump housing and the driving device is radially, and the permanent magnet in the pump housing is corresponding with permanent magnet 3 positions in the driving device.
