Constant-temperature storage device for placenta stem cell extracting solution

Abstract

The invention relates to a constant-temperature storage device for a placenta stem cell extracting solution. A refined filtration membrane plays a role in filtering impurities, and a ultrafiltration membrane plays a role in extracting water from the stem cell extracting solution; the water circulated once can ensure that impurities above the refined filtration membrane are fully washed, and meanwhile, the water can be ensured to flow, so that the concentration of the stem cell extracting solution can be ensured to be relatively stable, and the activity of the stem cell extracting solution is further improved. Meanwhile, the temperature is measured at the water inlet pipe, the measurement position is the most accurate, the accuracy of temperature control is ensured, a temperature detector is not arranged at an active component of the stem cell extracting solution any more, the influence of temperature detection on the stem cell extracting solution can be reduced, the influence of the stem cell extracting solution on the temperature detector is also reduced, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to a medical storage device, in particular to a constant temperature storage device for placental stem cell extract. Background technique [0002] In recent years, stem cell research has attracted widespread attention from scientists and the world. Stem cells have extremely broad application prospects in the fields of cell repair in life sciences, developmental biology, and pharmacology. At present, the commonly used storage method of placental stem cell extract in the world is to store the obtained stem cell extract in a deep low temperature state. [0003] Application number CN201821610642.3 discloses a constant temperature storage device for placental stem cell extract, including a base and a condenser, the condenser is arranged inside the main body, and the end of the first wire is connected to a central processing unit. It is convenient to control the temperature and prevent temperature instability, thereby ensuring the qual...

Problems solved by technology

[0005] However, the various devices mentioned above, on the one hand, have a simple idea of ​​temperature control, and the temperature control accuracy is not high, and they are not perfectly suitable for stem cell extracts; because the temperature, fluidity and concentration of stem cell extracts have an impact on the storage life of stem cell extracts , so special devices should be set up to store
