Description

Technical Field

[0001] The utility model relates to the field of stem cell monitoring devices, in particular to a quality monitoring device for stem cells. Background Art

[0002] Stem cells have the ability to self-renew and also have the ability to differentiate into various types of cells, such as nerve cells, muscle cells, heart cells, etc., to repair damaged tissues and organs. In addition, stem cells play an important role in immune regulation. They can regulate the function of the immune system, prevent the occurrence of autoimmune diseases, and activate the activity of inhibitory cells for directed differentiation, thereby improving function.

[0003] In the process of stem cell culture and storage, quality monitoring devices are usually used to monitor them in order to ensure their quality. However, the commonly used monitoring method is still observation through a microscope. This method has some problems. For example, when the experimenter needs to adjust the position of the microscope, it is often necessary to move it manually. Such movement process will interfere with the monitoring of stem cell quality. In addition, if the microscope is placed on a desktop, once the height of the desktop is low, the experimenter needs to bend over for a long time to observe the stem cells. Maintaining a posture for a long time can easily make people feel tired.

[0004] Therefore, in view of the fact that the above-mentioned experimenters often need to move the microscope manually, which will cause interference to the monitoring of stem cell quality, a stem cell quality monitoring device can be designed. Through telescopic adjustment in conjunction with a threaded transmission structure and a gear transmission structure, the monitoring platform can be automatically moved while adjusting the position and height of the microscope, thereby avoiding the trouble of manual pushing by the experimenter.
