Technical Field

The invention relates to the field of medical equipment, in particular to a movable liver transfer box capable of uniformly controlling temperature.

Background

China is a country with high incidence of liver diseases, more than 1 hundred million patients with various liver diseases exist, and more than 800 million patients with end-stage liver diseases exist. The end-stage liver disease is a worldwide problem, and the fatality rate of the liver disease is up to more than 80%. The research on end-stage liver diseases is listed in the priority theme of population and health field in the national middle and long term development planning (2006-2020) in China. At present, liver transplantation is the most effective means for treating end-stage liver diseases, however, donor organ preservation is an important factor influencing transplantation prognosis, and since the middle of the 20 th century, various research centers continuously research and develop improved organ protection solutions, rapid development of Static Cold Storage (SCS) technology of organs based on the organ protection solutions is promoted, organ preservation is further free from time and region limitation, and development of organ protection enters a brand-new era. The development of organ transplantation is greatly promoted, and the SCS technology is still the most commonly used technology in organ preservation and is widely applied to most of the organ transplantation centers around the world.

SCS is the method which is most widely applied to the preservation of the liver at present, the most used cold preservation solution is University of Wisconsin solution (UW solution) and histidine-tryptophan-ketoglutarate solution (HTK solution), the metabolism of donor liver and the decomposition of enzymes can be effectively reduced under the low temperature condition, so that the consumption of oxygen-free respiration in the liver on energy and the accumulation of harmful substances such as lactic acid are reduced, the operation is simple and convenient, and the cost is lower. In addition, in the organ transfer process, the UW liquid can be stored for 20-24h theoretically, and convenience is provided for trans-regional and trans-central transplantation.

To sum up, most of the SCS methods are to soak the liver in an organ preservation solution, then place the liver in an organ transport box filled with ice bags, and transport the liver between hospitals or across regions. This leads to a situation where the liver may be in close contact with the ice pack locally due to gravity and not displaced for a long time, resulting in partial liver freezing. In the operation of receptor liver, after the liver is taken out, the liver can not be completely rewarming by conventional rewarming, and the rewarming degree is difficult to evaluate; this results in poor local liver perfusion during the blood recirculation, local short-term no perfusion, and severe complications such as hypothermia in the recipient, cardiac arrest, and primary nonfunctional postoperative liver.
