The invention relates to a PRP preparation device and a PRP preparation method, the preparation device comprises a pipe body, an upper cover, a lower cover and a sealing plug, the pipe body comprises an upper section pipe, a middle pipe and a lower section pipe, the upper cover and the upper section pipe are matched to form an upper cavity, the upper cover can move up and down to enable the upper cover to be switched between a first position and a second position, and the upper cover is provided with a liquid injection and suction hole, a liquid suction pipe and a sealing piece; the lower cover is matched with the lower section pipe to form a lower cavity, and the lower cover can move up and down to adjust the volume of the lower cavity; the sealing plug is used for controlling opening and closing of the liquid injection and suction hole and the liquid suction pipe; the part, located in the upper cavity, of the pipette has a set length, and the set length enables the pipette to be located in the platelet-poor plasma layer and keep a gap with the platelet-rich plasma layer when the pipette is located at the second position, and enables the port of the pipette to be located outside the platelet-rich plasma when the port of the pipette is located at the first position. By applying the device, the PRP concentration can be directly adjusted in the preparation device, and the damage to platelets can be avoided when the PRP is extracted.

The application discloses a volume-adjustable liquid supplementing tank and a carbon capture system, and relates to the technical field of carbon dioxide capture and transportation. The volume-adjustable liquid supplementing tank comprises a tank body, the tank body comprises a first chamber and a second chamber arranged in sequence, a plurality of unit chambers are arranged in the second chamber, the chamber volumes of the plurality of unit chambers are adjustable and the plurality of unit chambers are used for storing different solvents, each unit chamber is provided with a first liquid outlet, a liquid conveying pipe in communication with the first chamber is connected to the first liquid outlet, an electromagnetic valve is arranged on the liquid conveying pipe, the first chamber is used for temporarily storing the solvents discharged from at least one unit chamber, and the first chamber is provided with a second liquid outlet. The volume-adjustable liquid supplementing tank can realize the supplement of the solution obtained by mixing a plurality of solvents according to a set ratio and the quantitative supplement of a single solvent, and the volume of the unit chamber can be adjusted, the storage amount of the easily-consumed solvents is increased, and the liquid supplementing efficiency is ensured.

The application relates to a feeding structure, in particular to a block-type rotary feeding structure and a feeding device with the same. The block-type rotary feeding structure comprises a hopper with a tapered part; a feeding seat connected with the tapered part of the hopper and communicating with the inside of the hopper, the inside of the feeding seat is formed with a through channel, opposite side walls of the through channel are formed with symmetrically arranged arc-shaped grooves, so that a cylindrical space is formed in the through channel; a rotary ladle rotatably connected with the feeding seat and arranged in the cylindrical space; and a driving member connected and installed on the feeding seat, the driving member is used for driving the rotary ladle to rotate, and the through channel is always in a blocked state. The application is novel in design, axial rotation is used for feeding instead of traditional auger feeding, material blocking can be effectively prevented, and open fire in a furnace can be effectively blocked to the hopper, so that the safety hidden danger of fire in the hopper is eliminated.
