An isolated heart-lung combined perfusion system and perfusion method

Abstract

The purpose of the present invention is to provide an isolated heart-lung combined perfusion system and perfusion method, which uses organ perfusion to preserve isolated organs, avoids ischemia-reperfusion injury caused by low temperature storage, and solves the problem that isolated heart-lung organs cannot be perfused simultaneously The problem of preservation, including organ compartment, circulation compartment, control compartment, simple breathing compartment, cardiac pacemaker, imaging and control panel, base, the organ compartment is connected with the circulation compartment, control compartment and simple breathing compartment , the control cabin is connected with the imaging and control panel, the organ compartment, circulation cabin, control cabin, simple breathing cabin, imaging and control panel are installed on the base, the simple A simple ventilator is placed in the breathing cabin, and the simple ventilator and cardiac pacemaker are respectively connected with the isolated heart and lung to form an isolated cardiopulmonary support system, and the cardiac pacemaker monitors and outputs signals to the control cabin, The control cabin controls the work of the cardiac pacemaker.

Description

technical field [0001] The invention relates to the technical field of organ transplantation, in particular to an isolated heart-lung combined perfusion system and a perfusion method. Background technique [0002] Organ transplantation is an effective means of treating end-stage organ diseases. At present, about 300,000 people are still waiting for organ transplantation, so every donor is very precious, so it is very important to do a good job in perfusion preservation of donors. [0003] With the development of heart and lung transplantation technology, more and more attention has been paid to the protection of donor heart and lung. The preservation quality of donor heart and lung directly affects the survival rate of patients after organ transplantation. At present, in clinical practice, the isolated heart and lungs are mainly preserved by low temperature immersion in organ preservation solution. Storage time in vitro. However, the low temperature storage time is general...
