Passive thoracic pressure differential pressure artificial heart and implantation position

Abstract

The invention relates to a passive thoracic pressure differential pressure artificial heart, wherein the middle chamber of the left heart sac is a left ventricle, and the outer shape of the left heartsac is a special-shaped hollow capsule corresponding to the outer curved surface of the left ventricle. The upper end of the left heart sac is communicated with the left ventricle tube A and the front end of the left ventricular tube A is provided with a mitral valve. The mitral valve is constrained by the left atrial joint in the end of the left ventricular tube A tube and the inner tube of theleft atrial joint. The lower end of the chamber in the left ventricle communicates with the left ventricle tube B, and the rear end of the left ventricular tube B being an aortic valve. The aortic valve being constrained within the end of the left ventricular tube B and the tube of the aortic tube by the aortic tube. The invention has no need of pumping and external power supply and control, and can avoid the fatal complications such as hemolysis, infection and the like.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a passive thoracic pressure difference artificial heart and its implantation position. Background technique [0002] The principle of the artificial heart in the prior art is: the artificial auxiliary pump body (peristaltic pump / diaphragm pump) is implanted into the chest cavity, and the blood flow is driven into the left or right ventricle through the pump body to partially or completely replace the pumping function of the heart. There are big limitations in the artificial heart of prior art. First of all, this method has a series of contraindications and requires complex processes such as external power supply and control, so the practical application range is very limited. Secondly, the current ventricular assist device needs to be in direct contact with blood, and a series of fatal complications such as bleeding, thrombus, hemolysis, infection, and immune reaction will inevita...

AI Technical Summary

Problems solved by technology

The artificial heart of the prior art has great limitations

First of all, this method has a series of contraindications and requires complex processes such as external power supply and control, so the practical application range is very limited

Secondly, the current ventricular assist device needs to be in direct contact with blood, and a series of fatal complications such as bleeding, thrombus, hemolysis, infection, and immune response will inevitably occur

Third, this method can only temporarily replace the left heart pumping blood, and its service life is limited
