Description

Separation method and system thereof

The present invention relates to a separation method and a centrifugal system, and more particularly to a method and system for separating a solution in a sealed environment to ensure that the components of the separation solution are pure.

Today's centrifuges have been widely used in various fields, such as the chemical field and the medical field. The principle is to use the powerful centrifugal force generated by the high-speed rotation of the centrifuge rotor, and use the centrifugal force to accelerate the sedimentation speed of the particles in the solution, and separate the sedimentation coefficient and the mass of the mass in the solution, wherein the formula of the centripetal acceleration is known. The object with a higher density is below, and the object with a lower density is above.

In the medical field, the conventional blood centrifugation system is used to separate various components in the blood, such as high-concentration platelet plasma and platelet-poor plasma, which is gradually receiving attention from the medical community and the medical beauty industry. High-concentration platelet plasma (Platelet Rich Plasma) , PRP) contains high concentrations of growth factors, such as: PDGF aa, PDGF bb, PDGF ab, IGF-I, IGF-II, TGF-alpha, TGF-beta, EGF, VEGF, can treat tendonitis, acute and chronic muscles Pulling, ligament sprain, loss of articular cartilage, rheumatoid arthritis, etc., can also be used to inject into the skin, repair tissue, cell activation, improve pigmentation, acne scars, wounds, and cavities. Platelet Poor Plasma (PPP) can be applied to the filling technique, which can make the platelet-free plasma into a filling of autologous collagen and implant it into the skin. It can be changed immediately. Good wrinkles, legal lines, depressions, etc., the effect can last for three to four months. Therefore, it is possible to isolate high-concentration platelet plasma and platelet-poor plasma with high economic value.

However, the conventional technique is to house the blood in a centrifuge tube. After the centrifugation is completed, the operator inserts the syringe into the centrifuge tube, and the collection form is manually collected, and the extraction is more likely to occur during the extraction process. Red blood cells, and the plasma collected by such separation method cannot directly collect high-concentration platelet plasma and platelet-poor plasma. After the collection, the platelet plasma must be separated from the high-concentration platelet plasma. Further, the volume of the centrifuge tube is small, each time. The centrifugation requires collection of plasma in a plurality of centrifuge tubes, which is cumbersome and complicated. Therefore, the conventional blood centrifugation system cannot be directly used after the collection is completed, and must be extracted through the syringe in the collected sample before being injected and used, and when extracted, it is easy to cause the extraction component to be affected due to inadvertent operation. Pollution.

For example, U.S. Patent Publication No. 5,514,070 A discloses a centrifugal device for injecting a solution to be separated into a device via a line, and rotating the solution to be separated at a high speed.

Among them, such technology implies several problems, one of which is that the structure of the centrifugal device includes a stator and a rotor, and both of them must generate friction when rotating at a high speed, and the user cannot ensure the presence or absence of impurities under high-speed friction. The second is that the external pipeline is equipped with a pressure valve so that the separated solution to be separated is not closed during the entire separation process, and it is not known whether it is possible to leak impurities from the pressure valve, so the rigor of the overall separation step is not known.
