Description
Technical Field
The invention belongs to the technical field of living cell separation systems, and relates to an efficient separation system for adult small animal myocardial cells.
Background
The primary cultured adult myocardial cells are widely used in the research processes of cardiovascular disease mechanisms, cardiovascular drug development and myocardial toxicology screening. The perfusion separation system of the existing adult myocardial cell separation system of small animals mainly comprises two or more than two glass water bath thermostats, peristaltic pumps and circulating water bath pots (DL Nature Life sciences, TYPE 803; Radnoti,120107 EZ; Shanghai Orkets, ALC-M). Because the existing adult myocardial cell separation system comprises two or more serially connected glass water bath thermostats, the initial perfusion liquid and the digestive enzyme liquid sequentially enter the heart through the same pipeline, the accurate control of the crossing time between different liquids is very difficult, and meanwhile, the system cannot be used independently of a peristaltic pump, so that the investment cost is increased.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide an efficient separation system for adult small animal myocardial cells, which is used for solving the problem that the final separation effect is influenced because the crossing time between initial perfusion liquid and digestive enzyme liquid is difficult to accurately control in the separation experiment process of the myocardial cells.
The purpose of the invention can be realized by the following technical scheme:

5) the perfusion main path has a simple structure, so that on one hand, the constant temperature tube for heating is close to the heart for the experiment, the perfusion main path heating device additionally used for ensuring the temperature control problem in the conventional perfusion device is avoided, on the other hand, the flow in the perfusion main path is favorably shortened, the perfusion liquid passing through the three-way valve can directly and quickly reach the heart for the experiment, the problem that the experiment accuracy is influenced by the delay of the solution switching time due to the excessive residual liquid in the pipeline is avoided, and the accurate and quick solution switching effect is favorably realized;
5) according to the invention, the perfusate or digestive enzyme liquid flowing out of the liquid inlet pipe enters the corresponding liquid outlet pipe through the exhaust pipe, and the diameter of the exhaust pipe is larger than that of the liquid inlet pipe and the liquid outlet pipe, so that the perfusate or digestive enzyme liquid is kept at a certain liquid level height in the exhaust pipe, and bubbles entrapped in the perfusate or digestive enzyme liquid are broken and dissipated from the liquid level, and are discharged from the emptying pipe together with air remained in the pipeline, thereby avoiding the problem that the separation experiment of the myocardial cells is influenced because the bubbles enter the main perfusion path.
