[0001] This application claims priority of Italian Patent Application No. UD2005A000112 filed on Jul. 1, 2005. FIELD OF THE INVENTION [0002] This invention relates to a cardiocirculatory aiding device, namely, to a hematic pump to be associated to the heart, whose characteristics are in accordance with the precharacterizing part of the main claim. [0003] The use is substantially directed to assist the heart, but also to replace it in extremis with two of these elements (Right and Left). BACKGROUND OF INVENTION [0004] As known in the cardiosurgery practice, some mechanical aiding devices of the heart are used, commonly defined Ventricular Assist Device (V.A.D.) or Total Artificial Heart (T.A.H.). [0005] We refer substantially to devices able to mechanically pump the blood, producing pulse or continuous hematic flows. [0006] Such devices are used to solve reversible acute cardiac insufficiency clinical cases (e.g.: infarct, myocarditis, morphological pathologies, postcardiotomy, etc . . . ) or are used for supporting the circulatory function awaiting a heart transplantation or even indefinitely in case of situations or irreversible chronic problematic pathologies "Therapy destination". [0007] Different ventricular aid devices have been present for many years, for both left and right aid or biventricular (T.A.H.); some of them are commercially available, other have been developed only to experimental level. PROBLEMS AND DRAWBACKS OF THE BACKGROUND ART [0008] In the majority of the cases the existing devices have some difficulties of housing inside the chest, due to dimension and weight problems, as well as in the application modalities. [0009] Other noticeable drawbacks are due to their internal geometries and to their pumping modalities that can cause, in respect of the blood, hemolysis or formation of coagulations. [0010] Another negative aspect is caused by the weight and the encumbrance of the operating unit, associated to the pumping device that limits or precludes the portability of the whole complex. [0011] An additional problem created by the current devices is that they include complex internal mechanisms and, given the complexity, they are not completely reliable. [0012] In fact it is known that the more an apparatus is complex, the more probabilities of jamming danger there are. [0013] Furthermore the well-known devices incorporate electric and/or electromagnetic apparatus, with all the consequences and the dangers thereof. [0014] Finally it is known that such apparatus need more separate groups that must be housed in different positions of the body with further complications and important encumbrances and infection danger. [0015] Furthermore in case of jamming or stopping of the device, there is poor immediate possibility of intervention from outside, endangering the user's life. SCOPE OF THE INVENTION [0016] The scope of the invention is to solve the above-mentioned problems and drawbacks, by simplifying strongly the apparatus and furthermore: [0017] to improve the functionality and performances; [0018] to increase the performance; [0019] to improve the reliability; [0020] to adjust easily the apparatus; [0021] to reduce its encumbrance and its weight; [0022] to eliminate any electric part to be installed inside of the human body; [0023] to be able to intervene in case of emergency from the external of the human body without the necessity of complex apparatus, but being able to pump in emergency also with the simple use of the hands; [0024] use in pediatric cases. SOLUTION OF THE PROGRAM AND DISCLOSURE OF THE INVENTION [0025] The problem is solved with the characteristics of the main claim. [0026] The subclaims represent advantageous preferred solutions that supply best performance. ADVANTAGES Continue reading...
