The platelet production device 1 includes a placement frame 11 and a production tube 12 arranged inside the placement frame 11. A snap ring 111, a plurality of connecting posts 112 are installed between the two snap rings 111, a top cover 13 is provided on the top of the generating cylinder 12, a turbulent flow system 14 is arranged inside the generating cylinder 12, and the turbulent flow system 14 includes a spline shaft 141, The bottom of the spline shaft 141 is equipped with an upper blade 142, the bottom of the upper blade 142 is equipped with a telescopic column 143, the bottom of the telescopic column 143 is equipped with a lower blade 144, and the top side of the top cover 13 is equipped wit...

Embodiment 2

[0052] As the second embodiment of the present invention, in the specific operation process, the turbulent flow system cannot be completely simulated only by the rotating blades. In order to obtain clean platelets, kinetic energy must be generated to force the quasi-platelets to split themselves. 141 to make improvements, as a preferred embodiment, such as Figure 8 to Figure 11 As shown, the upper end of the spline shaft 141 is equipped with an upper mounting plate 1411, the bottom of the upper mounting plate 1411 is provided with a fixed cylinder 1412, the inner top of the fixed cylinder 1412 is equipped with a telescopic cylinder 1413, and the bottom of the telescopic cylinder 1413 is provided with a connecting plate 1414 The top of the connecting plate 1414 is provided with a plurality of mounting screws 1415, the bottom of the connecting plate 1414 is provided with a telescopic shaft 1416, the top of the telescopic shaft 1416 is provided with a plurality of mounting holes ...

Embodiment 3

[0061] As a third embodiment of the present invention, in order to facilitate the vacuum adsorption of the culture solution, the inventors set up a vacuum suction device 2, as a preferred embodiment, such as Figure 12 As shown, the vacuum suction device 2 includes a hollow tube 21, a piston pad 22 is arranged inside the hollow tube 21, a push rod 23 is installed on one end of the piston pad 22, and a push plate 24 is arranged on the other end of the push rod 23. The outer wall of empty pipe 21 is equipped with liquid suction port 25 and liquid discharge port 26 respectively, and the outer wall of liquid suction port 25 and liquid discharge port 26 is all equipped with common valve 27, and liquid suction port 25 and liquid discharge port 26 are all connected with hollow tube. 21 connected.

[0062] In this embodiment, the piston pad 22 is made of rubber material, which has a certain degree of elasticity, and the overall sealing effect is good.

[0063] Further, the size of th...

Abstract

The invention relates to the mechanical technical field, and in particular, relates to a device for artificially synthesizing platelets in vitro in a fluid motion mode, wherein the device includes a platelet production device, a vacuum suction device and a platelet enrichment device. According to the device and method for artificially synthesizing the platelets in vitro in the fluid motion mode, ablood turbulence system in vivo can be simulated by a self turbulence device, the platelets are induced to produce, quasi platelet aggregation is forcibly prevented, and a kinetic energy to force quasi platelet self-splitting is applied, the clean platelets are obtained, and no platelet antibodies exist. The platelets produced by the method have huge yield and no significant difference from the function of mature platelets in vivo, and can be directly applied in clinic; because of no screening by the immune system in vivo, the produced platelets have no obvious antigenicity and no platelet antibodies are produced.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a device for artificially synthesizing platelets in vitro in a fluid motion mode. Background technique [0002] At present, the platelets used clinically all come from the platelet donation in voluntary blood donation. Because donating platelets takes a long time, the wound is large, and the process of returning to the donor body through extracorporeal circulation makes the source of platelets scarce. Nowadays, platelets are clinically used. has been in short supply. Secondly, many patients with blood diseases need long-term regular platelet transfusions, which can easily produce anti-platelet antibodies, resulting in ineffective platelet transfusions and posing a major threat to the safety of patients' lives and properties. Therefore, it is imperative to synthesize platelets in vitro. In recent years, some scientists have used the maturity of human induced pluripotent stem c...
