Embodiment Construction

[0037] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0038] Such as figure 1 As shown, a device for perfusion of isolated animal organs, comprising:

[0039] The liquid storage component 1 stores the perfusion solution;

[0040] The temperature control component 2 maintains the temperature of the perfusion solution being transported;

[0041] Oxygenation component 3, which introduces oxygen into the perfusion solution being transported to make it produce oxygenation;

[0042] The perfusion component 4 is used to perfuse the solution into the liver of the animal to be perfused.

[0043] Such as figure 2 , image 3 with Figure 4 As shown, the liquid storage assembly 1 is a transparent cylindrical container with a capacity scale bar, and the container cover is provided with a return conduit interface 11 , a liquid outlet interface 12 and a liquid injection valve 13 . The height is 20cm, the ...

Abstract

The invention relates to an in-vitro animal organ perfusion device which comprises a liquid storage component, a temperature control component, an oxygenation component and a perfusion component, wherein the liquid storage component is used for storing a perfusion solution; the temperature control component is used for maintaining the temperature of the perfusion solution in transportation; the oxygenation component is used for introducing oxygen into the perfusion solution in transportation to generate an oxygenation effect; the perfusion component comprises an outer-layer heat insulation subsystem and an inner-layer perfusion subsystem, the inner-layer perfusion subsystem comprises a perfusion chamber with a cover, a perfusion tube and a bile drainage tube are arranged on the cover, theperfusion chamber is divided into an upper layer and a lower layer by a perforated partition for holding a to-be-perfused animal liver, and the lower layer is connected to the liquid storage componentthrough a recovery pipeline. The in-vitro animal organ perfusion device provided by the invention has the benefits that a controllable temperature environment and a perfusion solution oxygen concentration environment are provided on the basis of realizing an animal perfusion technique; more changeable and perfect experimental conditions can be provided for a related in-vitro animal organ tissue experiment; in the experiment process, a temperature probe, an oxygen concentration probe and a pH probe of the device can provide more experiment data.

Description

technical field [0001] The invention belongs to the technical field of animal experiment equipment, and in particular relates to a perfusion device for isolated animal organs. Background technique [0002] In the study of organ transplantation modeling and organ ex vivo observation / intervention in experimental animals, in vitro perfusion is a commonly used research method. The traditional in vitro perfusion technology requires each experimental center to independently design relevant in vitro perfusion and The preservation of related instruments increases the difficulty of experiment implementation, prolongs the experiment cycle, increases the cost of the experiment, and prolongs the learning cycle of researchers to a certain extent. [0003] For some animal organ transplantation experiments and organ observation experiments in vitro, there is currently a lack of a systematic in vitro perfusion and preservation device to provide a stable and controllable external environment...
