PRP is widely used in various surgical operations, heart surgery and plastic surgery, and is also widely used in medical cosmetology. However, how to extract highly concentrated and high-quality PRP from the blood conveniently and quickly is the key to a successful PRP operation At present, PRP has been well clinically applied in medical surgery treatment, bone disease treatment, etc., and has a good therapeutic effect on disease prevention and rehabilitation of patients. It will be widely used in medicine and cosmetic treatment.

Blood is composed of plasma, platelets and blood cells. Because platelets contain various growth factors, they play an important role in wound healing and skin regeneration. Therefore, in medicine, blood separators are often used to separate blood to obtain platelets. Traditional blood During the separation process, the blood is usually injected into the separation tube, and then the separation tube is controlled to rotate at high speed to realize the separation of plasma, platelets and blood cells. When the traditional separation tube is working, the platelets and blood cells are separated at both ends of the separation tube. For suction and use, after the blood separation is completed, the blood cells need to be suctioned and tested. During the blood cell suction and transfer process, the blood cells will be exposed to the air, which will affect the detection accuracy. Therefore, the design of the sealing cover is required. The aspirated environment for blood cells is isolated.

At present, in the application of technology based on automatic separation and extraction of PRP, only the sealing cover is placed at the transfer connection for isolation. Although it effectively plays the role of environmental isolation, the air inside the sealing cover cannot be effectively purified. During the process, not only the gas cannot be effectively treated, but also it is easy to breed bacteria inside the sealed cover after long-term use, causing cross-infection of blood cells inside the sealed cover and affecting the detection accuracy. It is beneficial for personnel to carry out dynamic observation, so an air circulation and purification system for the sealing cover of the automatic separation and extraction PRP device is needed to solve the above problems.
