Dual-cavity liquid storage tank for biological artificial liver support system

Abstract

The invention discloses a dual-cavity liquid storage tank for a biological artificial liver support system. The dual-cavity liquid storage tank comprises an inner cavity and an outer cavity, wherein the top of the outer cavity is provided with a first liquid inlet and a first air pressure balance hole; the top of the inner cavity is provided with a second liquid inlet and a second air pressure balance hole; the bottom of the inner cavity is provided with a first liquid outlet; the side wall, which is close to the bottom, of the inner cavity is provided with a second liquid outlet; the second liquid outlet passes through the outer cavity by means of a pipelike passage, and directly leads to the outside of the dual-cavity liquid storage tank from the inner cavity; and the pipelike passage is provided with a plurality of outer cavity side holes on the partial side wall of the outer cavity. The dual-cavity liquid storage tank for the biological artificial liver support system realizes that severe hepatitis plasma flows through a bioreactor for multiple times to form a high-efficiency circulation path, thereby playing better therapeutic effect. The proportion of volume sizes of the inner cavity and the outer cavity of the dual-cavity liquid storage tank for the biological artificial liver support system can also be reset according to clinical concrete practical requirements, and is expanded or reduced so as to be applied to clinic treatment more reasonably.

Description

technical field [0001] The invention belongs to the technical field of biomedicine and relates to a medical device, in particular to an important device applied to the treatment of a bioartificial liver and which can effectively improve the therapeutic effect of the bioartificial liver: a dual-chamber fluid storage pool for a bioartificial liver support system. Background technique [0002] At present, liver failure is a critical condition with rapid progress and high mortality rate. The treatment of liver failure has always been a worldwide problem. At present, the artificial liver treatment has become an irreplaceable treatment for severe hepatitis liver failure, especially the bioartificial liver can theoretically compensate all the functions of the liver, which represents the development trend of artificial liver in the future and is facing a huge clinical demand. It has broad clinical application prospects. The basic principle of the bioartificial liver is that the pat...

Problems solved by technology

The artificial liver device lacking a liquid reservoir causes the patient's blood (plasma) to return to the body after one cycle, which makes the patient's blood (plasma) and cells lack sufficient material exchange, and the treatment efficiency of the bioartificial liver is low

Most artificial liver devices are equipped with liquid reservoirs, but most of them are single-chamber structures. Although multiple cycles can be achieved, the structural defects cannot avoid the situation that the blood (plasma) that has not passed through the reactor is directly returned to the body, that is, the so-called invalid loop
