Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of centrifuges, in particular to an automatic proportioning centrifuge. Background Art
[0002] A centrifuge is a machine that uses centrifugal force to separate liquids from solid particles or the components of a liquid-liquid mixture. Centrifuges are primarily used to separate solid particles from liquid in a suspension, or to separate two immiscible liquids of different densities in an emulsion (for example, separating cream from milk). They can also be used to remove liquid from wet solids, such as when washing wet clothes. Special ultra-fast tubular separators can also separate gas mixtures of varying densities. Some sedimentation centrifuges can also classify solid particles by density or size, taking advantage of the fact that solid particles of varying density or size settle at different rates in a liquid.
[0003] Various blood processing systems now enable the collection of specific blood components from a blood source, rather than whole blood. Blood component separation is typically achieved using a centrifuge. Currently, before centrifuging blood, test tubes should be placed symmetrically to ensure balance during the centrifugation process, so that the weights of the test tubes in relatively symmetrical positions are equal or similar, thereby avoiding vibration during centrifuge operation. Traditional methods require laboratory technicians to weigh the serum to ensure balance during the centrifugation process, which is cumbersome and time-consuming. Therefore, an automatic proportioning centrifuge has been proposed. Utility Model Content
[0004] Based on the above description, the present invention provides an automatic proportioning centrifuge to solve the problems in the above background technology.
[0005] The technical solution of the utility model to solve the above technical problems is as follows:
[0006] An automatic proportioning centrifuge comprises a centrifuge body, a drive motor is arranged inside the centrifuge body, an output end of the drive motor is connected to a turntable, a serum centrifugal chamber and a counterweight chamber are arranged on the top surface of the turntable, a test tube is placed inside the serum centrifugal chamber, a counterweight tube is arranged inside the counterweight chamber, weight sensors are arranged at the bottom of the serum centrifugal chamber and the counterweight chamber, and a material feeding component for inputting a medium into the counterweight tube is arranged on the top surface of the centrifuge body.
[0007] On the basis of the above technical solution, the present invention can also be improved as follows.
[0008] Furthermore, a mounting frame is fixedly installed on the top surface of the centrifuge body, a main pipe is fixedly installed on the surface of the mounting frame, a branch pipe is fixedly installed on the bottom surface of the main pipe, a solenoid valve is provided on the surface of the branch pipe, a feeding assembly is provided on the top surface of the centrifuge body, and a cover plate is hingedly installed on the top surface of the centrifuge body.

[0010] Furthermore, the number of the counterweight bins is four and they are located on the right side of the turntable, and the serum centrifugal bins are arranged correspondingly to the counterweight bins.
[0011] Furthermore, the top surfaces of the test tube and the counterweight tube are provided with sealing covers, and the number of the weight sensors is eight groups.
[0012] Furthermore, the branch pipes are provided in four groups and are arranged corresponding to the counterweight pipes.
[0013] Furthermore, the feeding assembly includes a storage box fixedly mounted on the top surface of the centrifuge body, a micro-delivery pump fixedly mounted on the surface of the storage box, a connecting pipe fixedly mounted on the surface of the micro-delivery pump, and the connecting pipe is fixedly connected to the main pipe.
[0014] Furthermore, a handle is fixedly mounted on the top surface of the cover plate, a display screen is provided on the front surface of the centrifuge body, and operation buttons are provided on the front surface of the centrifuge body.
[0015] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0016] The automatic proportioning centrifuge, through the setting of the feeding component, conveys the medium in the storage box to the main pipe. The solenoid valve on the branch pipe is opened to add the medium to the counterweight tube. The weight sensor provided at the bottom of the counterweight tube can quickly obtain the mass of the medium in the counterweight tube.

At the same time, multiple groups of serum centrifugal bins are provided, so that multiple bottles of serum can be centrifuged simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

By providing multiple groups of serum centrifugal chambers 4, multiple bottles of serum can be centrifuged at the same time, and test tubes 6 are placed inside the serum centrifugal chamber 4.
[0029] The top surface of the turntable 3 is provided with a counterweight bin 7, the number of which is four and is located on the right side of the turntable 3. The serum centrifugal bin 4 and the counterweight bin 7 are arranged correspondingly. The arrangement of the counterweight bin 7 facilitates ensuring the balance during the centrifugation process. Weight sensors 5 are provided at the bottom of the serum centrifugal bin 4 and the counterweight bin 7. A counterweight tube 8 is provided inside the counterweight bin 7. A sealing cover 9 is provided on the top surface of the test tube 6 and the counterweight tube 8. The number of weight sensors 5 is eight.

A main pipe 10 is fixedly installed on the surface of the mounting bracket 15. A branch pipe 11 is fixedly installed on the bottom surface of the main pipe 10. Four groups of branch pipes 11 are provided, and are arranged corresponding to the counterweight pipe 8.

Start the micro-transfer pump 13 to transport the medium in the storage box 12 to the main pipe 10. Open the solenoid valve 20 on the branch pipe 11 to add the medium into the counterweight tube 8. The mass of the medium in the counterweight tube 8 can be quickly obtained through the weight sensor 5 set at the bottom of the counterweight tube 8.

There is no need to manually weigh the blood, and the weight of the test tube 6 and the counterweight tube 8 in the relatively symmetrical position can be equal or similar, thereby avoiding vibration during the operation of the centrifuge body 1.
