Description

Technical Field

[0001] The utility model belongs to the technical field of centrifuges, and particularly relates to a centrifuge. Background Art

[0002] Existing high-speed centrifuges applied in the fields of biology, chemistry, medicine, etc. are used to separate biological samples.

[0003] After conventional biological samples (such as blood) are centrifuged and separated by a high-speed centrifuge and then chromatographed, it is necessary to measure the volume of the chromatographic solution of each layer of each component of the biological sample. In the prior art, after centrifugation by a high-speed centrifuge, generally, the chromatographic solutions of each layer in the test tube are transferred to a specific test tube by manual pipetting, and then the volume of the chromatographic solution is measured and calculated. However, when batch testing biological samples, using the above measurement method, the labor cost is too high, the workload is large, and the time consumption is long.

[0004] In the prior art, the patent "ZL201520661675.0" discloses a high-speed centrifuge. The test tube jacks on the high-speed centrifuge are arranged at an inclined angle with the central axis of the centrifuge. A plurality of test tube jacks are arranged circumferentially along the rotating shaft, and the bottom of each test tube jack is inclined downward and outward. And the orifices of the plurality of test tube jacks are all located on an inclined surface, and the inclined surface gradually approaches the rotating shaft of the high-speed centrifuge downward.

[0005] The chromatographic interface of each layer of the biological sample in the test tube after being centrifuged by the above high-speed centrifuge is an inclined surface. After using a CCD camera of an automated device to take pictures of the interface of each layer of the chromatographic solution, because the chromatographic interface is an inclined surface, different positions of taking pictures will cause the automated system to be unable to accurately calculate the volume of each layer of the chromatographic solution.

[0051] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0052] Such as Figures 1-6As shown in the figure, in this embodiment, a centrifuge is further provided. The centrifuge includes a centrifugal rotation assembly 1, a centrifugal chamber assembly 2, a CCD camera assembly 4, a vacuum assembly 5 that communicates with a vacuum chamber and is used for vacuum pumping, and a control assembly. The centrifugal chamber assembly 2 includes a vacuum chamber. The centrifugal rotation assembly 1 includes a driving device 12 and a rotating body 11 disposed in the vacuum chamber. The rotating body 11 is connected to the output shaft of the driving device 12, and the driving device 12 can drive the rotating body 11 to rotate around the central axis of the rotating body 11, that is, the R axis in the figure. At least two swinging containers 13 are circumferentially provided on the rotating body 11, and the swinging containers 13 have openings for inserting a sample container to be tested.

[0053] A photographing window 211 is circumferentially provided on the centrifugal chamber assembly 2. The CCD camera assembly 4 is disposed outside the centrifugal chamber assembly 2 and faces the photographing window 211.

[0054] When the rotational speed of the driving device 12 is a preset rotational speed, the swinging container 13 rotates to a horizontal state; when the swinging container 13 is in a vertically suspended state and stops at the photographing window, the CCD camera assembly 4 photographs the interface of the chromatography solution in the sample container to be tested in the vertically suspended state.

[0055] It can be understood that when the swinging container 13 is in a vertically suspended state, the swinging container 13 is vertically arranged. If the sample container to be tested fixed in the swinging container 13 is a test tube, the axis of the test tube is vertical at this time; when the swinging container 13 is in a horizontal state, the swinging container 13 is horizontally arranged. If the sample container to be tested fixed in the swinging container 13 is a test tube, the central axis of the test tube is coaxial with the radial direction of the rotating body 11 and is in a horizontal state at this time, that is, when the swinging container 13 switches from the vertically suspended state to the horizontal state, it rotates 90°.

[0056] Photograph the chromatography solution in the sample container to be tested in the vertically suspended state. The control assembly is electrically connected to the CCD camera assembly, the vacuum assembly, and the centrifugal rotation assembly. The control assembly controls the vacuum assembly to pump vacuum in the vacuum chamber, controls the driving device 12 to work, and drives the rotating body 11 to rotate. The control device controls the CCD camera assembly 4 to work, and at the same time can process the pictures taken by the CCD camera assembly and calculate the volume of each layer of chromatography solution.

[0057] In this embodiment, the driving device 12 is located outside the vacuum chamber, and the rotating body 11 is located inside the vacuum chamber. The driving device 12 drives the rotating body 11 to rotate. During the centrifugation process of the rotating body 11 from low speed rotation to high speed rotation, the swinging container 13 rotates from the vertically suspended state to the horizontal state, and the opening of the swinging container 13 faces inward, that is, in the horizontal plane, the swinging container can rotate 90° around an axis perpendicular to the radial direction of the rotating body 11 (such as Figure 2 shown as the R axis) (such as Figure 2The S-axis shown). The sample container to be tested is inserted and fixed in the swinging container 13. After the driving device 12 rotates at a high speed for a predetermined time for centrifugation, the sample in the sample container to be tested completes chromatography. Since the swinging container 13 rotates to the horizontal state when rotating at a high speed (rotating at a preset speed), the chromatography interface of each layer of chromatography liquid is a plane. When the swinging container 13 rotates at a low speed (rotating at a first preset speed), it is in a suspended state. At this time, the chromatography interface of each layer of chromatography liquid is a horizontal plane. Therefore, the CCD camera assembly can automatically capture the separation interface of each layer of chromatography liquid of the sample to be tested and calculate the volume of the chromatography liquid. This centrifuge is suitable for automated detection production, eliminating the need for manual suction of the chromatography liquid for subsequent detection, with low cost and improved work efficiency.

[0058] The above-mentioned rotating body 11 includes a rotating body 111, and a rotating support portion 112 is circumferentially arranged on the rotating body 111. The swinging container 13 includes a fixed support member for fixing the swinging container 13, and the fixed support member is installed on the rotating support portion 112. When the rotating body 111 rotates, the swinging container 13 rotates from the vertically suspended state to the horizontal state.

[0059] Preferably, the rotating body 111 is a planar body. The structure of the rotating body 111 is simple, facilitating processing, with low cost and easy assembly with the swinging container 13.

[0060] Specifically, the swinging container 13 is rotatably installed on the rotating body 111, such that during the high-speed centrifugal rotation of the rotating body 11 driven by the driving device 12, the swinging container 13 can rotate from the vertically suspended state to the swung-out state under the action of centrifugal force. When the swinging container 13 is in the vertically suspended state, the sample container to be tested fixed in the swinging container 13 is vertically arranged. When the swinging container 13 is in the swung-out state, the swinging container 13 is usually horizontally arranged, that is, the swung-out state is a position where the swinging container 13 rotates 90° relative to the vertically suspended state. The sample container to be tested fixed in the swinging container 13 is horizontally arranged. When the centrifugal rotation ends and the speed of the centrifuge decreases or stops rotating, the swinging container 13 rotates back to the vertically suspended state under its own gravity.

[0061] Preferably, the above-mentioned fixed support member is a rotating shaft 132.

[0062] Preferably, a head receiving groove 113 is provided on the rotating body 111, and the rotating support portion 112 is opened in the head receiving groove 113. Before the rotating body 11 rotates after the sample container to be tested is installed in the swinging container 13 and when the swinging container 13 is in the vertically suspended state, the head of the sample container to be tested is located outside the swinging container 13. After the rotating body 11 rotates, the sample container to be tested rotates, and when the swinging container 13 is in the swung-out state, the head of the sample container to be tested is located in the head receiving groove 113.

[0063] Preferably, the rotary support portion 112 is a rotating shaft groove, which can be a separate component or a groove formed in the head receiving groove 113. The rotating shaft 132 rotates in the rotating shaft groove, and the rotating shaft 132 is clamped in the rotating shaft groove.

[0064] Preferably, the range of the preset rotation speed is 1000 r / min - 12000 r / min. The preset rotation speed of the rotating body 11 ensures that the sample container to be tested placed in the swinging container 13 is in the swung-out state. Specifically, for the sample in the sample container to be tested, the rotation speed and centrifugation duration for chromatography are determined according to research and development. After the rotation speed and centrifugation duration are determined, parameters can be set to make the driving device 12 start to work.

[0065] Preferably, the above-mentioned driving device 12 is a rotary motor. The rotary motor is arranged below the rotating body 11, and the output shaft of the rotary motor is connected to the rotating body 11 to drive the rotating body 11 to rotate.

[0066] Preferably, a plurality of swinging containers 13 are circumferentially and uniformly distributed on the above-mentioned rotating body 11. The swinging containers 13 are circumferentially and uniformly distributed along the rotating body 11 to facilitate centrifuging a plurality of samples to be tested simultaneously at one time. Specifically, in this embodiment, the number of swinging containers 13 is 16. Further, the number of swinging containers 13 is an even number. Preferably, every two swinging containers 13 are symmetric about the rotation axis of the rotating body 11 to improve the rotation stability of the rotating body 11.

[0067] After the centrifugal chromatography of the above-mentioned sample to be tested is completed, the rotation speed of the driving device 12 decreases, and the swinging container 13 gradually becomes in the vertically suspended state. In this state, the CCD camera 42 photographs the liquid surface area of each layer of chromatography solution of the sample to be tested and calculates the volume of each layer of chromatography solution. Preferably, the above-mentioned photographing window 211 is a transparent window, which is convenient for the CCD camera 42 to take pictures while ensuring the sealing of the vacuum chamber. At the same time, the CCD camera can also scan the bar code on the sample container to be tested to record the sample to be tested, corresponding to the sample container to be tested that generates chromatography after centrifugation, so as to realize automated production.

[0068] Preferably, the above-mentioned CCD camera assembly 4 is installed on the centrifugal chamber assembly 2. Specifically, the centrifugal chamber assembly 2 includes a chamber member 21 and an upper cover 22. The upper cover 22 can be covered or opened with the chamber member 21. A vacuum chamber groove 210 is formed on the chamber member 21. Specifically, the vacuum chamber groove 210 is a circular groove. A vacuum chamber is formed after the upper cover 22 and the chamber member 21 are covered.

[0069] The above-mentioned CCD camera assembly 4 is installed on the above-mentioned chamber member 21. Further specifically, the above-mentioned CCD camera assembly 4 includes a camera bracket 41 and a CCD camera 42. The camera bracket 41 is installed on the chamber member 21, and the CCD camera 42 is installed on the camera bracket 41. The CCD camera 42 faces the above-mentioned photographing window 211.

[0070] Alternatively, the above centrifuge further includes a frame and a camera bracket 41 mounted on the frame.

[0071] Preferably, the above cavity member 21 is a solid integral structure, which is convenient for the heating component 3 to heat the vacuum chamber and keep the vacuum chamber warm.

[0072] Preferably, the pressure range after the vacuum chamber is evacuated is 0 to -0.05 Mpa. In this embodiment, the pressure in the vacuum chamber cannot be 0, and the pressure value is less than 0. Specifically, the vacuum pressure value in the vacuum chamber is determined according to the type of the specific sample to be measured. Specifically, the vacuum assembly 5 includes a vacuum pump 51, and the vacuum pump 51 is arranged below the centrifugal chamber assembly 2, with a compact structure to save the overall volume of the centrifuge.

[0073] The centrifuge further includes a heating component 3, and the heating component 3 is arranged in the centrifugal chamber assembly 2 to keep the temperature of the vacuum chamber at a preset temperature.

[0074] In this embodiment, by heating the centrifugal chamber assembly 2 with the heating component 3, the vacuum chamber is kept at a constant preset temperature, and when the sample in the sample container to be measured is centrifuged at a high speed, chromatography can be completed faster.

[0075] Preferably, the heating component 3 includes a heating rod 31 and a temperature detection device 32. The temperature detection device 32 is arranged in the vacuum chamber to monitor the temperature in the vacuum chamber in real time. The heating rod 31 is embedded inside the centrifugal chamber assembly 2 and is used to heat the centrifugal chamber assembly 2, and heat is transferred to the vacuum chamber through air heat dissipation to keep the temperature in the vacuum chamber at a constant temperature. The above temperature value is selected according to specific needs.

[0076] Preferably, the heating rod 31 is embedded inside the cavity member 21, and the heating component 3 is embedded inside the centrifugal chamber assembly 2, and the two are in close contact. The vacuum chamber is heated by heat transfer to keep the vacuum chamber at a constant preset temperature. And the heat is transferred to the vacuum chamber by heat radiation to ensure the uniform temperature in the vacuum chamber.

[0077] Specifically, in this embodiment, there are four groups of heating rods 31, which are arranged in a quadrilateral shape on the outer periphery of the rotating body 11. The number of heating rods 31 can be determined according to actual needs.

[0078] Preferably, the centrifuge further includes a base 6 and a housing 7. The driving device 12 is installed on the base 6. Specifically, in this embodiment, the rotating motor is installed on the base 6, and the above-mentioned vacuum pump 51 is installed on the base 6 and is located below the cavity member 21. The above-mentioned housing 7 is arranged outside the centrifugal rotating assembly 1. A screen control assembly 8 and a vacuum display 9 are installed on the housing 7. The screen control assembly 8 is used to input instructions into the centrifuge. Specifically, the screen control assembly 8 is a display screen, and parameters such as rotation speed and centrifugation duration are input through the display screen to control the operation of the driving device and the vacuum pump. The vacuum display 9 is used to display the pressure value in the vacuum chamber in real time.

[0079] The above-mentioned vacuum assembly 5 is electrically connected to the screen control assembly 8. When the vacuum display 9 shows that the pressure in the vacuum chamber is less than a predetermined value, the screen control assembly 8 will automatically control the vacuum assembly 5 to start working according to the preset pressure value.

[0080] Preferably, at least two groups of support members 10 are arranged on the base 6. The cavity member 21 is installed on the support members 10. The support members 10 support the cavity member 21 to a preset height, leaving enough installation space for the driving device 12 and at the same time reducing the overall weight of the centrifuge.

[0081] Preferably, the support member 10 is a support column.

[0082] Preferably, the above-mentioned upper cover 22 is rotatably connected to the housing 7, and the upper cover 22 can be closed and opened with the cavity member 21.

[0083] As Figure 7 and Figure 8 shown, after centrifugation by the centrifuge, the interface of each layer of chromatographic solution generated by the sample to be tested is in a planar state. The interface of each layer of chromatographic solution is obtained by taking a photo with a CCD camera, and then the volume of each layer of chromatographic solution is calculated.

[0084] The working principle of the above-mentioned centrifuge: When the centrifuge works, an operator presses the power switch, and the control assembly controls the heating assembly 3 to start heating, and at the same time controls the vacuum assembly 5 to evacuate the vacuum chamber. When the pressure in the vacuum chamber reaches the predetermined pressure value and the temperature reaches the constant preset temperature, the control assembly controls the driving device 12 to start working. The driving device 12 drives the rotating body to rotate centrifugally, and the sample container to be tested installed in the swinging container 13 rotates accordingly. When the rotation speed of the driving device 12 reaches the preset rotation speed, the sample container to be tested rotates from the vertical hanging state to the horizontal state. At this time, the opening of the swinging container 13 faces inward (i.e., the opening faces the rotation center of the rotating body).

[0085] After the rotating body drives the swinging container 13 and the sample container to be measured to rotate in the vacuum chamber for a preset time, the sample in the sample container to be measured completes chromatography. The rotation speed of the driving device 12 decreases. At this time, the swinging container 13 and the sample container to be measured fall from the horizontal state to the vertically suspended state. The driving device drives each sample container to be measured on the rotating body to rotate to the photographing window 211 and stop. The CCD camera 42 takes a picture of the sample container to be measured and transmits the photographing information to the control component. Through the control component, the volume of the chromatography solution in each layer in the sample container to be measured can be accurately calculated. If there are multiple layers of chromatography solution, the volume of each layer of chromatography solution can be calculated separately at one time.

[0086] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here.
