Structure and mechanism of the screen–enrich–combine(-biomaterials) circulating system (SECCS). (A) Plastic pipe: contains a detachable filtration device, a silastic tube, and 2 3-way cocks. (B) Detachable filtration device: consists of a cap, an inner box, and an outer box. (C,D) Bone marrow injection: by adjusting the 3-way cocks, nozzle.1 opens into nozzle.2, and nozzle.4 opens into nozzle.5, which means that channel.3 is closed. Bone marrow was poured into the pipe from nozzle.2, and air was exhausted via nozzle.4. (E,F) Formation of a sealed circulatory pipe: by adjusting the 3-way cocks, nozzle.1 is connected to nozzle.5 through channel.3. Thus, a sealed pipe is assembled for bone marrow circulation.
