Description
Technical field
The present invention relates to a kind of liver room temperature save sets.More particularly to a kind of portable liver room temperature save set.
Background technology
Since Thomas professors Starzl in 1963 successfully complete the 1st Clinical Liver Transplantation, Technology of Liver Transplantation in China development
Rapidly, become the main means for the treatment of End-stage liver disease.The whole world is increasingly serious for liver shortage situation at present, this problem is in China
Especially prominent, there are about 1,500,000 patients to need organ transplant every year in China, and carries out organ transfer operation only 10,000 or so every year,
A large amount of patients are dead because of donor organ shortage.With the continuous improvement of Chinese society civilization degree, the donor in Newgate saint source
Organ number falls sharply, and heart death is contributed (donation after cardiac death, DCD) and supplied as China's organ transplant
Person's main source becomes the main path for solving China's donor organ critical shortage.It is counted according to Chinese visible human organ donation center,
By on 03 01st, 2015 registered 35290 people of organ donation volunteer, witnesses and successfully contributed 3188, given treatment to organ
Failure patients 8866.But 13.4 hundred million All population capacities of opposite China, horizontal far below World Developed Countries, still having greatly can
For.
It is that DCD donor organs are second-rate, and lack science currently, seriously perplexing the problem of China's DCD organ donations
Appraisal procedure, not only seriously affect patient's prognosis, but also cause practical efficiency very low.For liver not only by the long period
Low perfusion, Warm ischemia injury, and Cryopreservation Injury is undergone, lead to primary idle, the function delay of liver transplantation in world wide
Restore incidence to gradually increase.The simple Cord blood technology of UW liquid that the eighties in last century occurs once was considered as Clinical Liver Transplantation hair
The milestone of exhibition, but UW Cord blood technologies itself can not accurately assess the vigor state for liver, will also be subjected to low temperature injury,
It is even more impossible to carry out injury repair, the ever-increasing clinical demand of the Marginal donor livers such as DCD cannot be satisfied at present.
As the novel mechanical Perfusion preservation technology for substituting the simple Cord blood of UW liquid, according to the maintenance temperature of perfusion system
Difference can be divided into hypothermic machine perfusion (hypothermic machine perfusion, HMP) and room temperature machine perfusion
(normothermic machine perfusion, NMP).HMP is conducive to the thorough lavation of intraorganic blood, is conducive to remove
Or dilution metabolic waste, while organ being constantly provided and is metabolized required energy, graft function delay can be significantly reduced
Incidence, effect are better than simple Cord blood.HMP technologies originate in the sixties, during which due to equipment and technology complexity etc.
It lies on the table.Now with increasingly serious for liver shortage situation, extending for the liver holding time, DCD increases for liver and Marginal donor liver, with
And HMP technologies, in the success in kidney transplant field, HMP technologies become liver transfer operation research hotspot again.
However NMP keeps normal metabolism and tissue self-repairing capability closer to physiological status.It is supplied with lasting maintenance
Liver blood vessel bed is open；Sufficient energy substrate and oxygen supply are provided, ensure metabolic demand decreased under low-temperature condition；
Metabolite and toxin are removed or diluted in time；It effectively removes in liver the advantages that remaining microthrombus.But NMP skills at present
The defects of that there are equipment is huge for art, technical sophistication limits the clinical application of NMP, therefore it is ten to develop portable, easy equipment
Divide important.
External NMP core technologies are also concentrated mainly on American-European a small number of developed countries.Such as Canada's EVLP systems, Britain
Organ-OX systems, U.S.'s Transmedic systems, LifePort systems, Dutch Organ-Assist systems etc..It is badly in need of in China
Liver room temperature preserves and recovery technique, but since such device technical difficulty is big, the country there is no such product, belongs to blank neck
Domain.Start within 2012, country starts 863 projects and " establishes complete organ preservation and external reparation system and heart death
The assessment of donated organs, screening criteria " (project number：2012AA021001), which fully considers and faces based on China's actual conditions
Bed demand, closely surrounds the core for improving Donor liver quality, and by a large amount of zoopery, the discarded organ experiment of clinic is abandoned often
The complicated huge defect of warm machine perfusion technical equipment, successfully develops portable, simple and stable, intelligentized device.
Patent 201410384703.9 discloses the kidney being kept in existence device of a kind of low temperature or subnormal temperature, has begun to examine
Consider and carry out organ preservation under subnormal temperature, improves the preservation quality of kidney, but without being used for Liver Allograft Preservation.Patent
201410016261.2 disclose a kind of device and store method preserving isolated organ, by way of machine perfusion and film
The conjunction of formula oxygen makes isolated organ obtain lasting nutrient and oxygen supply, however, its is simple in structure, each device is connected, fixed
And the poor reliability in structure, function are difficult to ensure.It is enhanced that patent 201510085562.5 discloses a kind of security protection
Organ hypothermia machine perfusion save set, the device carry out organ preservation, while the various control signals for passing through pump at low temperature
Realize different fill-up modes.However, the structure type is simple, each two pieces be fixedly connected and it is realisation poor.Specially
Sharp 201310723787.X discloses a kind of transplant organ protective bag, and the apparatus structure is simple, however the device also can only be low
Temperature is lower to carry out organ preservation, can not provide oxygen and blood circulation.
