Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the existing bioartificial renal tubule auxiliary device, and provide a bioartificial renal tubule bioreactor that replaces the human kidney. The bioreactor is composed of a plastic shell, a cell culture medium outlet, a cell culture medium inlet, a perfusate inlet, a perfusate outlet, a polysulfone membrane nanomaterial support layer, and hollow fiber tubes. The hollow fiber tubes are arranged in concentric circles, and the peristaltic pump The output end of the peristaltic pump is connected to the perfusate inlet of the bioreactor, the input end of the peristaltic pump is connected to the perfusate outlet of the bioreactor, the output end of the constant flow device is connected to the cell culture liquid inlet of the bioreactor, and the input end of the constant flow device The end is connected with the cell culture medium outlet of the bioreactor, and the bioreactor, peristaltic pump and constant flow device are placed in the incubator

Embodiment 1

[0017] see Figure 1-3 , the bioreactor provided by the present invention is made of bioreactor I, peristaltic pump II, cell culture fluid constant flow device III and incubator IV, bioreactor I is made of plastic shell 1, cell culture fluid outlet 2, cell culture fluid Inlet 3, perfusate inlet 4, perfusate outlet 5, polysulfone membrane nanomaterial support layer 6, and hollow fiber tube 7, the hollow fiber tube 7 is arranged in concentric circles, the output end of the peristaltic pump II and the perfusion of the bioreactor I The liquid inlet 4 is connected, the input end of the peristaltic pump II is connected with the perfusate outlet 5 of the bioreactor I, the output end of the constant flow device III is connected with the cell culture liquid inlet 3 of the bioreactor I, and the input end of the constant flow device III It is connected with the cell culture medium outlet 2 of the bioreactor I, and the bioreactor I, the peristaltic pump II and the constant flow device III...

Embodiment 2

[0019] Example 2 Large-scale culture of kidney-related cells

[0020] Using transdifferentiated renal tubular epithelial cells, press 5×10 7 The density per ml is planted on the outer chamber of the hollow fiber tube 7 in the bioreactor 1 and the surface of the polysulfone membrane nanomaterial support layer 6, and the culture medium is replaced 2-3 times a week, which can significantly increase the number of cultured kidney cells.

Embodiment 3

[0021] Example 3 Microcarrier culture of renal tubular epithelial cells in the outer cavity of hollow fiber tube 7

[0022] The microcarrier exogenous renal tubular epithelial cells can be input into the bioreactor I through the cell culture medium inlet 3 of the bioreactor I, so that the renal tubular epithelial cells are evenly distributed in the outer cavity of the hollow fiber tube 7 of the bioreactor I , and then the perfusate enters the cavity of the hollow fiber tube 7 of the bioreactor 1 through the perfusate inlet 4 of the bioreactor 1, and the renal tubular epithelial cells absorb the nutrients and oxygen in the culture solution through the semi-permeable membrane, release metabolites, and cultivate The liquid constant flow device III sends the culture liquid back to the culture bottle through the culture liquid outlet 2 of the bioreactor I. The exogenous renal tubular epithelial cells cultured by the method are used for treating the renal tubular epithelial cells fi...

Abstract

The invention provides a biological reaction device which replaces human kidney, consisting of a biological reactor, a peristaltic pump, a cell culture liquid constant-flow device and a constant temperature box; the biological reactor consists of a plastic shell, a pouring liquid inlet, a pouring liquid outlet, a cell culture liquid inlet, a cell culture liquid outlet, a sulfone film nanometer supporting layer and a hollow fiber pipe; the hollow fiber pipe is arranged in a concentric round; the peristaltic pump is connected with the pouring liquid inlet and the pouring liquid outlet of the biological reactor; the constant-flow device is connected with the cell culture liquid inlet and outlet of the biological reactor; the biological reactor, the peristaltic pump and the constant-flow device are arranged inside the constant temperature box; the biological reaction device has reasonable design and simple and convenient preparation, can replace the kidney function of acute renal failure and multiple organ dysfunction syndrome patient in long-term or leads the similar patients to gradually recover the self-kidney tissue and other functions, thus improving the survival rate of the multiple organ dysfunction syndrome patient and prolonging the survival time of the multiple organ dysfunction syndrome patients.

Description

technical field [0001] The invention relates to a medical device, in particular to an artificial renal tubule bioreactor temporarily replacing human kidneys. It specifically relates to a combination with a mechanical artificial kidney, which replicates the function of renal tubules, can replace renal function for a long time, and is used for the treatment of acute renal failure and multiple organ dysfunction syndrome, thereby improving multiple organ dysfunction. Survival and Prolonged Survival of Syndrome Patients with Bioartificial Tubular Bioreactors. Background technique [0002] Regardless of acute or chronic renal failure (ARF, CRF), or multiple organ dysfunction syndrome (MODS), although the clinical causes are different, there are acute tubular necrosis (ATN), hemodialysis Therapy, although it can replace the filtering function of the glomerulus, such as removing uremic toxins in the blood, and correcting the disturbance of the patient's water and electrolyte balanc...
