Combined bioartificial liver supporting system

Abstract

The invention discloses a combined bioartificial liver supporting system. The supporting system at least comprises branch pipelines connected in order, the branch pipelines are a blood input branch pipeline of which an upstream tail end is arranged to be a blood input end, a first slurry separating branch pipeline at least including a first plasma separator, a non- biological cleaning branch pipeline at least including a plasma hemoperfusion apparatus and a bilirubin absorber, a biological cleaning branch pipeline at least including a liver cell culture tank component, a plasma returning branch pipeline of which downstream tail end is arranged to be a blood output end; tee devices are connected among the first plasma separating branch pipeline, the biological cleaning branch pipeline and the non-biological cleaning branch pipeline, between the outlet end of the non-biological cleaning branch pipeline and the biological cleaning branch pipeline, and between an outlet end of the non-biological cleaning branch pipeline and the plasma returning branch pipeline; the tee devices comprise tee joints and branch paths connected with the tee joints; at least two branch paths are provided with current limiting pieces and connection pieces.

Description

technical field [0001] The invention mainly relates to the field of biology and the field of medical equipment, in particular to an artificial liver support system with multiple functions. Background technique [0002] my country is a country with a high incidence of liver disease, and liver disease will eventually develop into liver failure. Due to liver failure, the mortality rate of patients is relatively high, and treatment is also relatively difficult. Clinically, liver transplantation is currently the most effective treatment for liver diseases. Due to the scarcity of donors, high cost and rejection by the human immune system, the application of liver transplantation is limited. At the same time, while waiting for liver transplantation, the patient is still suffering from liver failure, and the patient's physique and physical condition may be affected to the point that he is not suitable for liver transplantation. [0003] At present, the artificial liver will prolong...

AI Technical Summary

Problems solved by technology

In the prior art, the function of the artificial liver is relatively simple, mainly purifying, to eliminate the accumulation of toxins in the patient's blood due to the loss or impairment of metabolic function caused by liver function impairment

Due to the single function of the existing artificial liver, it is impossible to deal with the comprehensive situation of patients with severe liver failure, and the patient needs to replace multiple machines, which leads to an increase in the cost of the patient, and also increases the physical burden and psychological pressure of the patient.

Switching between various machines will also increase the learning cost of technicians, increase the difficulty of operation, and increase the demand for storage space
