[0002] Cardiology is a hospital department specializing in the diagnosis and treatment of cardiovascular diseases. Cardiology's clinical work is complex and diverse, given the wide variety of cardiovascular diseases. Some cardiology treatments require stem cell extraction and transplantation using stem cell extraction devices to promote regeneration and repair of the cardiovascular system and reduce damage to the heart and blood vessels. Existing stem cell extraction devices typically extract blood using a standard syringe.

[0003] Existing stem cell extraction devices usually extract stem cells by drawing blood through an ordinary syringe during use. The stem cells drawn in this way are mixed with other components such as blood and tissue fluid, which can easily lead to low stem cell purity, thereby reducing the therapeutic effect of stem cells.

[0004] Therefore, in order to address the above-mentioned problem that the purity of stem cells is low and thus the therapeutic effect of stem cells is reduced, a clinical stem cell extraction device for cardiology can be designed. By combining a syringe with a suction structure, the suction structure can purify the aspirated stem cells after the staff aspirates the stem cells, thereby solving the above-mentioned problem.
