Temperature control system for liver perfusion

Abstract

The present invention discloses a temperature control system for liver perfusion. The system comprises a control module, a power module for supplying power to the temperature control system, a water tank for accommodating circulating water, a temperature regulator, a temperature monitoring component for monitoring the temperature of circulating water, and a centrifugal pump for driving circulatingwater into a pulmonary membrane oxygenator for heat exchange and returning the water to the water tank. The control module controls the temperature regulator to adjust the temperature of the circulating water according to the monitoring result of the temperature monitoring component, so that the temperature of the circulating water can be adjusted by using the temperature monitoring component andthe temperature regulator, and the temperature of the perfusate can be adjusted according to the temperature requirement of the liver perfusion.

Description

technical field [0001] The invention relates to the technical field of organ transplantation equipment, in particular to a temperature control system for liver perfusion. Background technique [0002] In the field of clinical medicine, three methods of low temperature preservation, low temperature perfusion and normal temperature mechanical perfusion are often used to preserve the isolated liver. Among them, cold preservation is to cool the liver evenly and rapidly to below 10 degrees, and then fully soak the liver in cold preservation. It is maintained in the temperature range of 1-10°C until it is transplanted. This is because low temperature is the basis for protecting and preserving cells, which can effectively resist ischemic damage and is easy to operate. However, under low temperature conditions, cells Edema, acidosis, calcium accumulation, and reduced enzyme activity cause cold storage to cause some damage to the liver, which in turn increases the probability of comp...

Problems solved by technology

[0003] Moreover, due to the limitation of perfusion equipment technology, in the process of cold preservation and low temperature perfusion, a low temperature working environment is often maintained in medicine by adding ice cubes, which is troublesome to operate and difficult to monitor the influence of temperature on the performance indicators of living livers. There is no relatively mature perfusion equipment for the perfusion device, and in the existing liver perfusion equipment, the heat exchange water tank and the main control system operate independently, which is bulky, inconvenient to operate, and inconvenient to carry
