Description
Technical Field
The utility model relates to a blood separation and extraction device, in particular to a blood separation and extraction device with a rubber plug.
Background
Blood is composed of plasma, platelets, and blood cells, wherein platelets contain components necessary for the regeneration and repair of human tissues. When blood is centrifuged, the blood is separated into Plasma, platelets, and blood cells according to the weight of the blood, and the platelets separated in this way are formed into Plasma Rich in Plasma, i.e., Platelet Rich Plasma (PRP: Platelet Rich Plasma) and Platelet Poor Plasma, i.e., Platelet Poor Plasma (PPP: Platelet Poor Plasma). Since platelets contain various growth factors, they have important effects on wound healing and skin regeneration. It has been reported that PRP contains the platelets at a high concentration, and thus, various growth factors promote the growth of peripheral cells, and have an effect of promoting sufficient synthesis of components such as collagen. Thus, PRP has recently been used in various fields such as treatment of pain such as lumbago, treatment of alopecia, skin regeneration, and skin diseases such as burn. The extracted blood was centrifuged, and the blood cell component and Platelet Poor Plasma (PPP) were separated and centrifuged again to extract only PRP. However, the separation method using the conventional blood separation and extraction device has a problem that blood is exposed to air during the process of moving to a centrifugal separation vessel or the process of moving to a separation vessel including a filter unit after blood collection. Chinese patent publication No. CN103566629B discloses a method and apparatus for separating and extracting blood-rich platelets, which can perform centrifugal separation on blood twice. However, in a container such as a blood separation and extraction device which requires a high level of blood contamination prevention, the rubber caps at the injection hole and the vent hole are liable to fall off and be contaminated during use, and the blood in the device is liable to be contaminated.
