Embodiment 1
[0044] Referring to the accompanying drawings, a culture device for suspending tissue cells includes a tissue cell culture body 2, which is a porous tantalum material; the porous tantalum material is based on the material pore size The grading cavity and the cavity wall surrounding the cavity are formed, and the lower-level small cavity is set around the cavity wall forming the upper-level large cavity; the cavities of each level are connected to each other, and the cavities of each level are also connected to each other. . The culture device also includes a cyclone device placed therein.
[0045] Specifically in this example, the porous tantalum material has three-level cavities, wherein the upper two-level large cavities 12 (hereinafter referred to as the first-level cavities) that are uniformly distributed and interpenetrated have uniformly distributed, Interconnected upper-level large cavities 14 (hereinafter referred to as second-level cavities), and evenly distributed a...
Embodiment 2
[0059] The cell culture body 2 of the tissue cell culture device of this embodiment is made of porous silica material, has two-stage cavities, uniformly distributed and interpenetrated upper-level macro-cavities 12 have evenly distributed and inter-connected lower-level cavities on the cavity wall 13 small cavity 14, and the two-stage cavity also communicates with each other. The pore diameter of the upper large cavity 12 is 20µm-80µm, and the pore diameter of the lower small cavity 14 is 100nm-300nm. The included angles θ1 and θ2 of outlet pipe ① 11, outlet pipe ② 12 and the horizontal plane are 15°, outlet pipe ① 11, outlet pipe ② 12 are equipped with a perforated diaphragm 16, and its average aperture is 0.3mm.
[0060] The preparation method of this kind of porous silicon dioxide material is:
[0061] (1) Material preparation
[0062] Use 1µm-10µm silica powder and urea with a particle size of 130nm-350nm as the smallest pore-forming agent, mix them evenly, and use 130nm...
Embodiment 3
[0070] The cell culture body 2 of the tissue cell culture device of this embodiment is made of porous titanium material and has three-level cavities, among which, the cavities of the upper two-level large cavities 12 (hereinafter referred to as the first-level cavities) that are uniformly distributed and interpenetrating On the wall 13 there are evenly distributed and interconnected upper-level large cavities 14 (hereinafter referred to as second-level cavities), and on the wall 15 of the upper-level large cavities there are evenly distributed and inter-connected lower-level small cavities ( Hereinafter referred to as the third-level cavity); and the cavities of all levels are also connected to each other. The aperture of the first-stage cavity 12 is 300µm-700µm, the aperture of the second-stage cavity 14 is 60µm-95µm, and the aperture of the third-stage cavity is 400nm-700nm. Be 45 °, air outlet pipe 1. 11, outlet pipe 2. 12 outlets are equipped with apertured diaphragm 16, a...
