[0002] In the prior art, the cartridge is formed as a turntable rotation drive structure for automatic measurement and is designed to be processed in each chamber. However, this method relies on the rotation of the turntable, so a fine flow path structure is required, and the upper plate and the lower plate need to be joined, which is relatively complicated and difficult to mass produce and manage. In addition, a large number of parts are required, so the cost of the cartridge is high, and there is a problem that the sample is difficult to inject.

[0040] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 1 is a cross-sectional view showing a centrifugal cartridge according to an embodiment of the present invention. Figure 3 This is a perspective view showing the centrifugal immunoassay device of one embodiment of the present invention, excluding the outer casing. Figure 4 1 is a block diagram showing an absorbance optical system according to an embodiment of the present invention. Figure 5 and Figure 6 This is a perspective view showing a centrifugal immunoassay device according to one embodiment of the present invention.

[0042] Reference Figures 1 to 6The centrifugal immunoassay device 10 of one embodiment of the present invention may be a device for separating a detection object from a sample and detecting the separated detection object. In this case, the centrifugal immunoassay device 10 may include a centrifugal cartridge 100, an absorbance optical system 200, a cartridge loading unit 300, a rotation driving unit 400, a horizontal driving unit 500, a syringe 600, a syringe driving unit 700, a housing 800, and a control unit.

[0043] The centrifugal cartridge 100 may be an all-in-one cartridge mounted on the centrifugal immunoassay device 10 to separate the detection object from the stored sample through a rotational motion and detect the separated detection object. In this case, the centrifugal cartridge 100 may include a sample well 110, a centrifugal separation well 120, a sample moving channel 130, a detection well 140, a cover 150, and a tube cap 160.

[0044] Before the centrifugal separation operation, the user injects a sample, and the sample well 110 may be a space for storing the injected sample. The sample may be whole blood B. As another example, the sample may be a urine sample.

[0045] The sample stored in the sample well 110 is moved by the rotation operation, and the centrifugal separation well 120 may be a space for storing the sample in a separated state. More specifically, the centrifugal separation well 120 may be configured to be separated from the sample well 110, and the centrifugal separation well 120 may be a space in which the sample stored in the sample well 110 is moved and stored by the centrifugal force generated by the rotation action. In addition, the centrifugal separation well 120 may be a space for storing a sample in a centrifugally separated state, wherein the sample is centrifugally separated according to the specific gravity of the substances constituting the sample.

[0046] At this time, the sample stored in the sample well 110 can move to the centrifugal separation well 120 through the sample moving channel 130. The sample moving channel 130 is a flow path formed by connecting the sample well 110 and the centrifugal separation well 120, and can be a channel through which the sample can only move from the sample well 110 to the centrifugal separation well 120. At this time, the sample moving channel 130 can be formed at a position above a preset height to prevent the centrifuged sample from moving back to the sample well 110. The preset height can be the height of the sample stored in the sample well 110 before the centrifugal separation operation.

[0047] The substance with a larger specific gravity in the sample in the centrifugal separation state may be precipitated at the lower part of the centrifugal separation well 120, and the substance with a smaller specific gravity in the sample in the centrifugal separation state may be located above the substance with a larger specific gravity, thereby being separated from the precipitated substance. As one embodiment, the substance with a smaller specific gravity in the sample in the centrifugal separation state may be a detection object. The detection object may be plasma P. As another embodiment, the substance with a larger specific gravity in the sample in the centrifugal separation state may be a non-detection object sample. In this case, the non-detection object sample may be red blood cells R.

[0048] The centrifugal separation well 120 may be formed with a step 121 at the bottom so as to suck only the detection object. More specifically, the centrifugal separation well 120 may be formed with a step 121 at the bottom so as to suck only the detection object in the centrifuged sample.

[0049] The step 121 may be a space for allowing the detection object stored in the centrifugal separation well 120 to be sucked by the suction head component 610 described later. The step 121 may be a space for inserting the suction head component in the upper part to extract the detection object. The step 121 may be formed at a preset position in such a way that only the detection object, which is a sample with a smaller specific gravity among the centrifuged samples, is arranged in the upper part. In this case, the preset position may be a position higher than the height of the precipitated sample with a larger specific gravity.

[0050] The centrifugal separation well 120 can ensure that the suction head component 610 only sucks in the test object by forming the step 121, thereby ensuring reproducibility and improving the accuracy of the test. Reproducibility can be the degree to which the measurement result values ​​are consistent when the same measurement object is measured by the same method under different conditions such as the measurer, device, measurement location, and measurement time.

[0051] The detection well 140 may be a space for receiving the detection object stored in the centrifugal separation well 120 and storing the detection object for detection. More specifically, the suction head part 610 that sucks the detection object stored in the centrifugal separation well 120 will spit out the detection object, and the detection well 140 may be a space for storing the spitted detection object.

[0052] The detection well 140 may be formed as a cuvette structure to enable transmission detection. A cuvette may be a small tubular container designed to store a sample in spectrophotometric measurement. The detection well 140 may be formed of a transparent material so that light generated by the absorbance optical system 200 described later passes through the detection object contained in the detection well 140 to measure the absorbance.

[0053] As one embodiment, the detection well 140 may be a plastic cuvette. Plastic cuvettes may be used for high-speed spectroscopic analysis where measurement speed is more important than accuracy, and may be discarded after use to prevent contamination during reuse. In addition, plastic cuvettes may be made of polymethyl methacrylate (PMMA) or polystyrene (PS), thereby being manufactured at a lower price than existing cartridges. However, the present invention is not limited to the above-described embodiments, and as another embodiment, the detection well 140 may be a glass cuvette. As another embodiment, the detection well 140 may be a quartz cuvette. At this point, the durability of the quartz cuvette is better than that of a plastic cuvette or a glass cuvette, and it is capable of transmitting light of a wider wavelength than that of a plastic cuvette or a glass cuvette.

[0054] The cover 150 may be formed to seal the upper surface of the centrifugal cartridge 100. The cover 150 can seal the upper surface of the centrifugal cartridge 100 to prevent the sample contained in the centrifugal cartridge 100 from escaping during centrifugation. At this time, the cover 150 can seal the upper surface of the centrifugal cartridge 100 except for the sample well 110 into which the sample is injected before centrifugation.

[0055] The cover 150 may be formed of a material that can be penetrated by the suction head component 610. As an embodiment, the cover 150 may be an aluminum cover formed by hot melting. However, the present invention is not limited thereto, and the cover 150 may be formed of a material that can be penetrated by the suction head component 610.

[0056] The tube cap 160 can open and close the sample well 110. Specifically, the tube cap 160 can be configured on the upper surface of the centrifugal cartridge 100 to open and close the sample well 110, thereby controlling the movement of substances entering and exiting the sample well 110. As one embodiment, the tube cap 160 can be separated from the sample well 110 before centrifugation to inject the sample into the sample well 110. As another embodiment, the tube cap 160 can be combined with the sample well 110 during centrifugation to prevent the sample from escaping from the sample well 110.

[0057] The absorbance optical system 200 can be combined with the detection well 140 injected with the detection object to perform transmission detection on the injected detection object. The absorbance optical system 200 can pass the light through the detection well 140 formed as a cuvette structure to measure the absorbance of the detection object. As an embodiment, the absorbance optical system 200 can use LED light with a wavelength of 340nm for detection. At this time, the light generated in the LED lens 210 can pass through the EX filter (Excitation filter) 220 and the DM filter (Dichroic Mirror filter) 230. The EX filter 220 and the DM filter 230 can only pass the light with the wavelength that the detection object absorbs the most. More specifically, the EX filter 220 can be a filter that only passes the light with a selected wavelength, and the DM filter 230 can be a special filter designed to reflect the light with excitation wavelengths and pass the light with emission wavelengths. The light passing through the EX filter 220 and the DM filter 230 can pass through the detection well 140 containing the detection object. The light passing through the detection well 140 is focused by the focusing lens 240, and the focused light can be used to calculate the detection value by the detection photodiode (PD) 250. In addition, the absorbance optical system 200 can be equipped with a monitoring photodiode (Monitoring PD) 260 to monitor the wavelength value of the light reflected by the DM filter 230.

[0058] The cartridge loading section 300 may be a device for storing the centrifugal cartridge 100 and the absorbance optical system 200. More specifically, the cartridge loading section 300 may have a cartridge hole larger than the centrifugal cartridge 100 so that the centrifugal cartridge 100 can rotate. In addition, the cartridge loading section 300 may be a space for combining the centrifugal cartridge 100 that has completed centrifugal separation with the absorbance optical system 200 to detect the absorbance of the object.

[0059] The rotary drive unit 400 is a device disposed inside the cartridge loading unit 300 for rotation, and can carry the centrifugal cartridge 100 and perform centrifugal separation. As one embodiment, the rotary drive unit 400 can rotate at a high speed of 4000 rpm. The rotary drive unit 400 can rotate at a high speed to move the sample stored in the sample well 110 to the centrifugal separation well 120 through the sample moving channel 130, and can separate the sample moved to the centrifugal separation well 120 into a detection object and a non-detection object sample.

[0060] As another embodiment, the rotation driving unit 400 may perform step rotation. More specifically, the rotation driving unit 400 may perform step rotation in a manner that the center of the suction head component 610 and the center of the centrifugal separation well 120 are in the same straight line when the suction head component 610 is inserted into the centrifugal separation well 120 to suck the detection object. In addition, the rotation driving unit 400 may perform step rotation in a manner that the center of the suction head component 610 and the center of the detection well 140 are in the same straight line when the suction head component 610 that has sucked the detection object spits the detection object into the detection well 140.

[0061] The horizontal driving unit 500 may be located at the lower part of the cartridge loading unit 300 to move the cartridge loading unit 300 in the horizontal direction. More specifically, when the cartridge loading unit 300 is viewed from the front direction (e.g., a direction parallel to the ZY plane), the horizontal driving unit 500 may be disposed on any one of the two side surfaces of the cartridge loading unit 300 to move the cartridge loading unit 300 in the horizontal direction (e.g., the X-axis direction or the -X-axis direction). At this time, the horizontal driving unit 500 may be provided with a guide rail G for moving the cartridge loading unit 300 in the horizontal direction.

[0062] The guide rail G may be formed to extend parallel to the moving direction (X-axis direction) of the horizontal driving unit 500. In this case, a guide protrusion protruding along the side direction (Y-axis direction) may be formed at the lower side end of the magazine loading unit 300. As an embodiment, the guide protrusion may extend along the circumference direction of the lower side end of the magazine loading unit 300 to connect with the guide rail G.

[0063] As another embodiment, the guide protrusion extends along the circumference direction of the lower side end of the magazine loading part 300, or may be formed only in a part of the circumference of the lower side end of the magazine loading part 300. In this case, the guide rail G may extend in parallel with the guide protrusion, and may be configured such that one surface of the guide rail G (hereinafter, the guide surface) is opposite to one surface of the guide protrusion. Therefore, when the magazine loading part 300 moves in the horizontal direction (X-axis direction or -X-axis direction), the guide protrusion can slide along the guide surface of the guide rail G, thereby preventing the magazine loading part 300 from tilting.

[0064] The syringe 600 is disposed at the upper portion of the cartridge loading portion 300, and can suck the detection object and inject it into the detection well 140. More specifically, the syringe 600 can be inserted into the upper portion of the step 121 formed at the lower portion of the centrifugal separation well 120 and suck the detection object, and can discharge the sucked detection object into the detection well 140. At this time, the syringe 600 may include a suction head component 610.

[0065] The suction head component 610 is disposed at the lower end of the syringe 600 and may be a portion for sucking and discharging the detection object. The suction head component 610 can penetrate the cover 150 on the upper surface of the centrifugal cartridge 100 to suck the detection object stored in the centrifugal separation well 120. At this time, the suction head component 610 may be formed to have a smaller diameter as it approaches the end portion so as to penetrate the cover 150. Thereafter, the suction head component 610 may discharge the sucked detection object into the detection well 140, which is a space for measuring absorbance.

[0066] The syringe driving unit 700 can move the syringe 600. More specifically, the syringe driving unit 700 can be driven in the up-down direction (e.g., the Z-axis direction or the -Z-axis direction) so that the syringe 600 can suck in and discharge the detection object. As one embodiment, the syringe driving unit 700 can be driven downward (-Z-axis direction) so that the syringe 600 can suck in the detection object accommodated in the centrifugal separation well 120. As another embodiment, the syringe driving unit 700 can be driven upward (Z-axis direction) so that the syringe 600 can discharge the sucked detection object into the detection well 140.

[0067] The housing 800 can cover the centrifugal cartridge 100, the absorbance optical system 200, the cartridge loading unit 300, the rotation drive unit 400, the horizontal drive unit 500, the syringe 600, and the syringe drive unit 700. In this case, the housing 800 may include a printer 810, a touch screen 820, a progress display 830, a power switch 840, and a door 850.

[0068] The printer 810 may be a thermal printer that applies heat to thermal paper to display text or patterns. More specifically, the printer 810 is a thermal printer as a non-impact printing device, and the thermal printer may be a printer that prints text or patterns in a dot manner by heating the thermal paper with heat from a print head. However, the present invention is not limited thereto. At this time, when the housing 800 is observed from the front direction (e.g., a direction parallel to the ZY plane), the printer 810 may be configured at the upper end of the housing 800.

[0069] The touch screen 820 can be used to receive a command from the user to operate the centrifugal immunoassay device 10. The touch screen 820 can be a contact display device that inputs a command using a part of the user's body such as a finger or a palm and a touch unit.

[0070] The touch screen 820 may include a command input touch key to enable the centrifugal immunoassay device 10 to perform a plurality of actions. As one embodiment, the touch screen 820 may include a start key and a pause key. However, the present invention is not limited thereto, and as another embodiment, the touch screen 820 may include a rotation operation key for performing centrifugal separation by the rotation drive unit 400, and a detection operation key for moving the centrifugally separated detection object to the detection well 140 and performing a detection operation.

[0071] The progress indicator 830 may be disposed on a surface of the housing 800 viewed from the front direction (eg, a direction parallel to the ZY plane) and displayed outwardly to allow the user to confirm the progress of the operation of the centrifugal immunoassay device 10 .

[0072] The power switch 840 may be a switch for turning on or off the power of the centrifugal immunoassay device 10. The power switch 840 may be disposed on a surface of the housing 800 viewed from the front direction (eg, a direction parallel to the ZY plane).

[0073] The door 850 can be opened and closed so that the user can load the centrifugal cartridge 100 on the centrifugal immunoassay device 10. In this case, the door 850 may be disposed on a surface of the housing 800 viewed from the front direction (for example, a direction parallel to the ZY plane).

[0074] The control unit can control the operation of the centrifugal immunoassay device 10 based on the command input by the user through the touch screen 820. More specifically, the control unit can control the absorbance optical system 200, the rotation drive unit 400, the horizontal drive unit 500, the syringe 600, and the syringe drive unit 700 based on the command input by the user through the touch screen 820.

[0075] As one embodiment, when the start button of the touch screen 820 is pressed, the absorbance optical system 200, the rotation drive unit 400, the horizontal drive unit 500, the syringe 600, and the syringe drive unit 700 can be controlled to enable the centrifugal immunoassay device 10 to centrifuge the sample by rotating the rotation drive unit 400, to move the syringe 600 up or down by the syringe drive unit 700, to cause the suction head component 610 of the syringe 600 to inhale and discharge the detection object, and to combine the centrifugal material box 100 with the absorbance optical system 200 to detect the detection object.

[0076] In addition, when a problem occurs during the operation of the centrifugal immunoassay device 10 , the pause key provided on the touch screen 820 can be pressed to pause the multiple operations being performed by the centrifugal immunoassay device 10 .

[0077] The centrifugal immunoassay device 10 of the various embodiments of the present invention described above can perform centrifugal separation and transmission detection using one centrifugal cartridge 100, thereby completing the detection process in a single device. Centrifugal separation and detection can be performed and the detection results can be confirmed using one centrifugal immunoassay device 10 and one centrifugal cartridge 100, thereby effectively shortening the detection time and cost.

[0078] The above description of the present invention is for illustration purposes only, and those skilled in the art will appreciate that the present invention can be easily transformed into other specific forms without changing the technical concept or essential features of the present invention. Therefore, it should be understood that the multiple embodiments described above are exemplary and non-restrictive in all aspects. For example, each component described as a whole can be implemented in a dispersed manner, and similarly, multiple components described as dispersed can be implemented in a combined form.
