Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and specifically discloses a sample centrifuge for detecting the concentration of tacrolimus in human whole blood. Background Technology

[0002] The detection of tacrolimus concentration in human whole blood requires the use of a sample centrifuge to centrifuge the sample tube. Existing centrifuges use a pressure plate installed inside the centrifuge via a threaded connection to compress and limit the sample tube placed inside the turntable. Each time a sample is tested, the pressure plate needs to be repeatedly disassembled and reassembled. Since the pressure plate cannot be directly and quickly disassembled, the disassembly and reassembly of the pressure plate is quite troublesome. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the prior art, this application aims to provide a sample centrifuge for detecting tacrolimus concentration in human whole blood, including a body, a control interface installed on the body, a top cover hinged to the top of the body, an electromagnetic lock installed inside the body, a drive shaft rotatably connected inside the body, and a turntable fixedly fitted on the outer side of the top of the drive shaft by a fixing sleeve, a placement hole provided inside the turntable, and a latch provided on one side of the bottom of the top cover and engaged inside the electromagnetic lock. A pressure plate is movably fitted on the outer side of the top of the drive shaft extending to the inner side of the turntable. A rubber pad is provided on the outer side of the pressure plate located inside the turntable. A first strong magnet is fixedly fitted inside the bottom of the top cover, and a second strong magnet is fixedly fitted inside the top of the pressure plate located directly below the first strong magnet. The opposing polarities of the first and second strong magnets are the same.

[0004] Preferably, a speed sensor located below the turntable is installed on the inner side of the machine body.

[0005] Preferably, both the top cover and the pressure plate are made of non-metallic materials.

[0006] Preferably, the outer side of the top end of the drive shaft is provided with a limiting boss that is adapted to the pressure plate. Beneficial effects

[0007] 1. The centrifuge for detecting tacrolimus concentration in whole blood uses a first and second strong magnet installed with the same polarity. When the top cover is closed, the magnetic force between the first and second strong magnets causes them to repel each other, thus pressing and limiting the pressure plate. When the top cover is opened, the first strong magnet can be removed from above the second strong magnet, thereby releasing the pressure plate. This structure allows for direct and quick assembly and disassembly of the pressure plate, making it convenient to use.

[0008] 2. The centrifuge used for detecting tacrolimus concentration in whole blood of this person can detect the actual rotation speed of the turntable through a speed sensor, and the real-time rotation speed of the turntable can be directly observed through the control interface. After the turntable stops rotating, the electromagnetic lock can be activated through the control interface to release the limit of the latch. However, the electromagnetic lock cannot be activated through the control interface while the turntable is rotating. Attached Figure Description

[0015] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0016] The accompanying drawings in this utility model embodiment: different types of cross-sectional lines in the drawings are not labeled according to national standards, nor do they specify the material requirements of the components. They are used to distinguish the cross-sectional views of the components in the drawings.

[0017] Please see Figure 1-4A sample centrifuge for detecting tacrolimus concentration in human whole blood includes a body 1, a control interface 2 mounted on the body 1, a top cover 3 hinged to the top of the body 1, an electromagnetic lock 4 mounted inside the body 1, a drive shaft 5 rotatably connected inside the body 1, and a turntable 7 fixedly mounted on the outer side of the top of the drive shaft 5 by a fixing sleeve 6, a placement hole 8 provided inside the turntable 7, and a latch 9 provided on one side of the bottom of the top cover 3 and engaged inside the electromagnetic lock 4. The control interface 2 is provided with a speed display interface electrically connected to a speed sensor 14. The drive shaft 5 extends to the outer side of the top of the turntable 7. A pressure plate 10 is fitted onto the outside of the pressure plate 10, and a rubber pad 11 is provided on the outside of the turntable 7. A first strong magnet 12 is fixedly fitted inside the bottom of the top cover 3, and a second strong magnet 13 is fixedly fitted on the inside of the top of the pressure plate 10, located directly below the first strong magnet 12. The opposing polarities of the first strong magnet 12 and the second strong magnet 13 are the same. The magnetic forces generated by the first strong magnet 12 and the second strong magnet 13 can repel each other, and the magnetic forces generated by the first strong magnet 12 and the second strong magnet 13 will not disappear when the pressure plate 10 rotates synchronously with the drive shaft 5.

[0018] The machine body 1 has a speed sensor 14 installed on the inside, located below the turntable 7. The speed sensor 14 can detect the speed of the turntable 7 in real time and can also be directly observed through the speed display interface on the control interface 2. Only when the speed is zero can the speed sensor 14 be activated through the control interface 2 to release the limit on the lock 9.

[0019] The top cover 3 and the pressure plate 10 are both made of non-metallic materials. By making the top cover 3 and the pressure plate 10 of non-metallic materials, the two will not interfere with the magnetic field generated by the first strong magnet 12 and the second strong magnet 13, thereby ensuring that the magnetic field force generated by the first strong magnet 12 and the second strong magnet 13 can press and limit the pressure plate 10.

[0020] The outer side of the top of the drive shaft 5 is provided with a limiting boss that is compatible with the pressure plate 10. The limiting boss can limit the pressure plate 10 and make the pressure plate 10 rotate synchronously with the turntable 7 under the rotation of the drive shaft 5, thereby ensuring that the sample tube can be stably fitted inside the placement hole 8.

[0021] When centrifuging the sample, press the top of the latch 9 with your hand, activate the electromagnetic lock 4 through the control interface 2, remove your hand from the surface of the top cover 3, and under the reverse force of the magnetic field generated between the first strong magnet 12 and the second strong magnet 13, the top cover 3 is lifted. After opening the top cover 3, remove the pressure plate 10 from the drive shaft 5, place the sample tubes symmetrically inside the placement hole 8, and fit the pressure plate 10 onto the outside of the drive shaft 5 through the limiting boss. While closing the top cover 3 and pressing down, the latch 9 is engaged inside the electromagnetic lock 4. Start the centrifuge through the control interface 2, and drive the sample tubes inside the turntable 7 to rotate through the drive shaft 5. The rotation speed of the turntable 7 is detected by the speed sensor 14. When the speed sensor 14 detects that the rotation speed of the turntable 7 is zero, the sample centrifugation is completed. Open the top cover 3 using the above steps, and finally remove the sample tubes from inside the placement hole 8. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
