Low speed large capacity centrifuge to understand its impact on the clinical use of blood components prevent manual collection of blood and low efficiency, the efficiency and quality of progress component of blood apheresis, development of automatic blood cell centrifuge is proposed. This article mainly aims at the belt type centrifugal separation pipe material, studied the mechanism of blood respectively collected, analyzed the influence factors of blood separation process, the planning of different components of blood apheresis order, design parameters and centrifugal mechanism touches the parting acquisition process, which lays the theoretical foundation for the follow-up engineering prototype development. Low speed large capacity centrifuge main research results found the thesis are as follows:
(1) studied the blood of centrifugal separation theory, aiming at the belt blood separation zone, set up the model of force blood particles in the separation in the pipeline, according to the stocks equation, analyzed the influence factors of centrifugal separation blood separation, put forward in the process of blood centrifuge in the development of control elements, and the way to adjust the design.
(2) low speed large capacity centrifuge to understand its in the ring parting with establishing model, meshing, boundary conditions on the basis of simulation research, stopped on the centrifugal separation process using FLUENT software. Analyzes effects of different pipe port construction, centrifuge speed and different collection line speed on the separation process, obtained the subsequent speed centrifuge design and blood component collection speed design principle, structural design and follow-up for centrifuge control provides according to.
(3) different for each component of single production process, design their parting acquisition process; acquisition simultaneously on different components of blood collection process of the planning; certainly the calculating method of the creeping pump speed is matched with the pipe material phase; consider the blood collection process safety foundation, see calculation method of safety parameters; stop the velocity gradient centrifuge speed management design, blood, transfusion speed.
(4) low speed large capacity centrifuge found its characteristic according to practice demand and pipe material, the design of centrifugal mechanism, and to ensure the smooth running of centrifuge system, rotary unit stopped dynamic balancing design and simulation.
This paper mainly discusses the mechanism of blood component separation, and the process, parameters and working process of the design. Look forward to the next step work needs to continue in-depth research in the following aspects:
(1) the blood separation parameter needs to stop the textual research on the experimental side, ensure the separation process parameters design in clinical on can reach the medical standard.
(2) low speed large capacity centrifuge to understand control its current blood level all rely on the beginning of the blood donation information input, the relevant control parameters are designed parameters calculated, sometimes there will be pre blood donors blood routine parameters influence the purity of imprecise separation problem, the future can consider CCD camera settings with the port in the parting, real time acquisition current layered system through blood, automatic control self adjusting acquisition interface, with the progress of the separation and purity.
(3) at present to design acquisition speed to complete different components of blood collection, the future can consider to continue to deepen the analysis, in view of each kind of different components of blood collection order designed specifically to further increase the separation efficiency and purity.
