Cystic cavity pulmonary circulation assisting device

Abstract

The invention relates to a cystic cavity pulmonary circulation assisting device, which comprises a shell, a flow-in tube (6) and a flow-out tube (4), wherein a blood storage cavity (A) and a power cavity (B) are arranged in the shell; the power cavity (B) is used for offering systolic and diastolic power to the blood storage cavity (A); the flow-in tube (6) is arranged on the part, which corresponding to the power cavity (B), of the shell, and the outer end communicates with vana cava while the inner end runs through the power cavity (B) and communicates with the blood storage cavity (A); theflow-out tube (4) is arranged on the part, corresponding to the blood storage cavity (A), of the shell, and the outer end communicates with pulmonary artery while the inner end communicates with the blood storage cavity (A). With the application of the assisting device, a single ventricular cavity can be assisted in pulmonary circulation, and repeated blood extracting and blood pumping actions canbe achieved, so that power required by pulmonary circulation can be offered and blood flow in the human body is close to be normal; and the circulating device is more compact in inner structure and is relatively small in overall volume since the arrangement of the flow-in tube occupies a space in the power cavity; and moreover, the full use of the power of the power cavity can be achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cystic cavity-pulmonary auxiliary circulation device. Background technique [0002] The Fontan procedure and its modifications are often used to treat congenital heart malformations that result in a functional single ventricle. With the advancement of surgical techniques and the development of postoperative monitoring measures, more and more children with functional single ventricle survive to adulthood. With the prolongation of the child's survival time, the limitations and long-term complications of the Fontan cycle began to appear, which greatly affected the quality of life of the child, leading to the failure of the Fontan cycle and heart transplantation. [0003] To solve this problem, dynamic Fontan cycle is one of the solutions. The Loye pump in the prior art is the first project approved by my country's FDA for clinical use, but the Loye pump is specially desi...

AI Technical Summary

Problems solved by technology

Clinically, there is still a lack of an autologous powered cavity-pulmonary assist device that can make full use of the kinetic energy of the single ventricle to improve the efficiency of the pulmonary circulation driven by the kinetic energy of the single ventricle, which is beneficial to the long-term survival of patients and the clinical promotion and use of such devices
