DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0039] The present application arranges two reagent trays on one side of the reaction tray to facilitate adding reagents into the reaction cup of the reaction tray. The two reagent trays are arranged front to back and then disposed at the rear end of the sample analyzer through a sample assembly, thereby reducing the overall depth of the sample analyzer, reducing the difficulty of operating the entire machine, facilitating subsequent maintenance, shortening maintenance time, and thereby improving test efficiency.

[0040] Embodiment 1

[0041] like Figure 1 to Figure 2 As shown, this embodiment provides a sample analyzer, including a carrier 100, a reaction disk 200, a first reagent disk 310, a second reagent disk 320, a reagent dispensing component and a detection component;

[0042] The reaction disk 200 is disposed on the carrier 100, and is used to load reaction cups, and the reaction cups are used for mixing samples and reagents to react;

[0043] The first reagent tray 310 and the second reagent tray 320 are disposed on the carrier 100 and are both located on one side of the reaction tray 200. The first reagent tray 310 and the second reagent tray 320 are arranged front and back in a distributed manner. The first reagent tray 310 and the second reagent tray 320 are used to contain the first reagent and the second reagent respectively.

[0044] The reagent dispensing assembly is disposed on one side of the first reagent tray 310 and the second reagent tray 320, and is used to pre-install the first reagent and the second reagent, and to distribute the pre-installed first reagent and the second reagent to the first reagent tray 310 and the second reagent tray 320, respectively;

[0045] The detection component is disposed on the carrier 100 and is used to detect the mixed liquid in the reaction cup.

[0046] During implementation, the carrier 100 is a carrying platform of the sample analyzer, and the reaction disc 200, the first reagent disc 310, the second reagent disc 320, the reagent dispensing assembly and the detection assembly are all arranged on the carrier 100. Among them, the reaction disc 200 is used to load the reaction cup, and the reaction cup is used for the sample and the reagent to mix and react. During use, the reaction disc 200 can rotate relative to the carrier 100, for example, the sample analyzer is provided with a motor, and the motor is connected to the reaction disc 200 to drive the reaction disc 200 to rotate.

[0047] Optionally, the sample refers to body fluid or some components in body fluid, for example, the sample may be blood or other secretions, without limitation.

[0048] The first reagent tray 310 and the second reagent tray 320 are both arranged close to the reaction tray 200, so as to facilitate adding the first reagent and / or the second reagent into the reaction cup. At the same time, in order to reduce the overall depth of the instrument, the first reagent tray 310 and the second reagent tray 320 are arranged front and back.

[0049] Alternatively, if Figure 1 As shown, the direction indicated by the arrow of line segment X can be regarded as the front end or front side of the sample analyzer. Similarly, the direction opposite to the direction indicated by the arrow of line segment X can be regarded as the rear end or rear side of the sample analyzer. The direction indicated by the arrow of line segment Y can be regarded as the right end or right side of the sample analyzer. Similarly, the direction opposite to the direction indicated by the arrow of line segment Y can be regarded as the left end or left side of the sample analyzer. In other words, the carrier 100 can be regarded as the top surface of the cabinet of the sample analyzer, which will not be described in detail.

[0050] In some embodiments, the first reagent tray 310 and the second reagent tray 320 are arranged on the left or right side of the reaction tray 200, without limitation. In addition, the first reagent tray 310 and the second reagent tray 320 are arranged front and back, and it can be regarded that the line connecting the center point of the first reagent tray 310 and the center point of the second reagent tray 320 is parallel or substantially parallel to the line segment X, thereby reducing the overall depth of the instrument.

[0051] Optionally, the first reagent disk 310 and the second reagent disk 320 may be single-circle reagent disks, so that the user can load reagents without distinguishing between inner and outer circles, thereby facilitating the absorption of reagents and ensuring test efficiency.

[0052] Optionally, the reagent dispensing assembly is disposed on one side of the first reagent tray 310 and the second reagent tray 320, for example, when the first reagent tray 310 and the second reagent tray 320 are located on the left side of the reaction tray 200, the reagent dispensing assembly is disposed on the left side of the first reagent tray 310 and the second reagent tray 320; or when the first reagent tray 310 and the second reagent tray 320 are located on the right side of the reaction tray 200, the reagent dispensing assembly is disposed on the right side of the first reagent tray 310 and the second reagent tray 320. That is, the reaction tray 200, the reagent tray and the reagent dispensing assembly are arranged along the line segment Y direction.

[0053] The reagent dispensing assembly is used to pre-install the first reagent and the second reagent. For example, the reagent dispensing assembly includes a reagent placement slot (not shown) located at the front end of the sample analyzer, and the user can place the reagent bottle containing the first reagent and the second reagent in the reagent placement slot. To prevent the first reagent and the second reagent from being mixed, two reagent placement slots can be provided, or one reagent placement slot can be separated, without limitation.

[0054] The reagent dispensing component can also distribute the pre-installed first reagent and the second reagent to the first reagent tray 310 and the second reagent tray 320 respectively. For example, the reagent dispensing component also includes a manipulator, which can accurately distribute the first reagent placed in the reagent placement slot to the first reagent tray 310 and accurately distribute the second reagent placed in the reagent placement slot to the second reagent tray 320 through the manipulator.

[0055] Through the above arrangement, the user can conveniently distribute the first reagent and the second reagent to the first reagent tray 310 and the second reagent tray 320. Moreover, since the reagent dispensing assembly, the reagent tray and the reaction tray are arranged along the line segment Y direction, the depth of the whole machine in the line segment X direction can be reduced. Even if other module components are installed at the rear end of the whole machine, the user can easily access other module components and operate or maintain other module components.

[0056] Optionally, the sample analyzer provided by the present application also includes a sample assembly, the sample assembly includes a sample suction track, a sample tube is placed on the sample suction track, and the sample tube is filled with a sample, and the sample suction track is arranged at the rear end of the sample analyzer, shortening the distance between the rear reagent tray and the front side of the sample analyzer. Exemplarily, taking the first reagent tray 310 close to the front side of the sample analyzer as an example, compared with the first reagent tray 310, the second reagent tray 320 is far away from the front side of the sample analyzer, that is, the distance between the front side of the sample analyzer and the second reagent tray 320 is shortened, and the user can also manually replace the reagent for the second reagent tray 320, further reducing the difficulty of replacing the reagent for the second reagent tray 320, shortening the reagent replacement time, and improving the test efficiency.

[0057] Optionally, the detection component has a light source, and the light emitted by the light source irradiates the reaction cup. The light passes through the mixed liquid in the reaction cup and is received by the detection component, thereby detecting specific components in the sample, for example, detecting specific chemical components through the principle of photoelectric colorimetry, which will not be elaborated here.

[0058] The sample analyzer of the present application includes a carrier 100, a reaction disk 200, a first reagent disk 310, a second reagent disk 320, a sample assembly and a detection assembly, wherein the reaction disk 200 is arranged on the carrier 100, the reaction disk 200 is used to load a reaction cup, and the reaction cup is used for the sample and the reagent to mix and react, the first reagent disk 310 and the second reagent disk 320 are arranged on the carrier 100 and are both located on one side of the reaction disk 200, the first reagent disk 310 and the second reagent disk 320 are arranged in a front-to-back distribution, the first reagent disk 310 and the second reagent disk 320 are used to hold the first reagent and the second reagent respectively, the reagent dispensing assembly is arranged on one side of the first reagent disk 310 and the second reagent disk 320, the reagent dispensing assembly is used to pre-install the first reagent and the second reagent, and distribute the pre-installed first reagent and the second reagent to the first reagent disk 310 and the second reagent disk 320 respectively, and the detection assembly is arranged on the carrier 100, and is used to detect the mixed liquid in the reaction cup. By arranging two reagent trays on one side of the reaction tray 200, and arranging the two reagent trays front and back, and then arranging the reagent dispensing assembly on one side of the first reagent tray 310 and the second reagent tray 320, the overall depth of the sample analyzer is reduced, and the difficulty of operating and maintaining the module components arranged at the rear end of the whole machine is reduced.

[0059] In some embodiments, the reaction disk 200 has a first placement groove and a second placement groove that are concentrically arranged, the first placement groove is arranged at the periphery of the second placement groove, and both the first placement groove and the second placement groove are used to carry reaction cups.

[0060] In practice, the reaction disk 200 is provided with an inner double ring, wherein the outer ring is the first placement slot, and the inner ring is the second placement slot. The first placement slot and the second placement slot are provided with a plurality of placement positions, and each placement position can be regarded as a slot for carrying a reaction cup, that is, the first placement slot and the second placement slot can each carry a plurality of reaction cups. Through the above setting, two items can be tested in the first placement slot and the second placement slot respectively, and the test speed reaches 2000T / H.

[0061] In some optional embodiments, the sample analyzer provided by the present application further includes a first sample needle 611 and a second sample needle 612;

[0062] The first sample needle 611 and the second sample needle 612 are both disposed between the reaction disk 200 and the sample assembly;

[0063] The first sample needle 611 is used to draw the sample from the sample tube and inject it into the reaction cup of the first placement slot;

[0064] The second sample needle 612 is used to draw the sample from the sample tube and inject it into the reaction cup in the second placement slot.

[0065] During implementation, since the reaction disk 200 is provided with two inner and outer circles of the first placement slot and the second placement slot, the first placement slot and the second placement slot can test different items respectively. That is, in order to add samples to the reaction cup on the first placement slot and the reaction cup on the second placement slot at the same time, two sample needles need to be set, wherein the first sample needle 611 is used to add samples to the reaction cup on the first placement slot, and the second sample needle 612 is used to add samples to the reaction cup on the second placement slot.

[0066] Optionally, since the sample assembly is arranged at the rear end of the sample analyzer, the first sample needle 611 and the second sample needle 612 are both arranged between the reaction disk 200 and the sample assembly, that is, the first sample needle 611 and the second sample needle 612 are both arranged at the rear end portion of the carrier 100, which is convenient for sucking samples from the sample tube of the sample assembly and then adding the samples to the reaction cups of the reaction disk 200.

[0067] In some optional embodiments, the sample analyzer provided in the present application further includes a first reagent needle 621, a second reagent needle 622, a third reagent needle 623 and a fourth reagent needle 624;

[0068] The first reagent needle 621 and the second reagent needle 622 are disposed between the first reagent disk 310 and the reaction disk 200, and the third reagent needle 623 and the fourth reagent needle 624 are disposed between the second reagent disk 320 and the reaction disk 200;

[0069] The first reagent needle 621 is used to absorb the first reagent from the first reagent disk 310 and inject it into the reaction cup of the first placement slot;

[0070] The second reagent needle 622 is used to absorb the first reagent from the first reagent disk 310 and inject it into the reaction cup of the second placement slot;

[0071] The third reagent needle 623 is used to absorb the first reagent from the second reagent disk 320 and inject it into the reaction cup of the first placement slot;

[0072] The fourth reagent needle 624 is used to absorb the first reagent from the second reagent disk 320 and inject it into the reaction cup of the second placement slot.

[0073] In implementation, since the reaction disk 200 is provided with the first placement slot and the second placement slot of the inner and outer circles, the first placement slot and the second placement slot can test different items respectively, that is, in order to add reagents to the reaction cups on the first placement slot and the reaction cups on the second placement slot at the same time, two reagent needles need to be provided. At the same time, since two reagent disks are provided, including the first reagent disk 310 and the second reagent disk 320, the first reagent disk 310 is used to hold the first reagent, and the second reagent disk 320 is used to hold the second reagent, that is, two reagent needles need to be provided for each reagent. That is, the first sample needle 611 and the second reagent needle 622 correspond to the first reagent disk 310, and the third sample needle and the fourth sample needle correspond to the second reagent disk 320, wherein the first sample needle 611 is used to absorb the first reagent from the first reagent disk 310 and add the first reagent to the reaction cup on the first placement slot, the second sample needle 612 is used to absorb the first reagent from the first reagent disk 310 and add the first reagent to the reaction cup on the second placement slot, the third sample needle is used to absorb the second reagent from the second reagent disk 320 and add the second reagent to the reaction cup on the first placement slot, and the fourth sample needle is used to absorb the second reagent from the second reagent disk 320 and add the second reagent to the reaction cup on the second placement slot.

[0074] Optionally, since the first reagent tray 310 and the second reagent tray 320 are arranged on one side of the reaction tray 200, the first reagent needle 621 and the second reagent needle 622 are arranged between the first reagent tray 310 and the reaction tray 200, and the third reagent needle 623 and the fourth reagent needle 624 are arranged between the second reagent tray 320 and the reaction tray 200, it is convenient to absorb and add reagents.

[0075] In some optional embodiments, the first reagent tray 310 is loaded with a first reagent bottle (not shown), and the second reagent tray 320 is provided with a second reagent bottle (not shown);

[0076] There are two intersection points between the moving tracks of the first reagent needle 621 and the second reagent needle 622 and the circle where the center of the bottle mouth of the first reagent bottle is located;

[0077] There are two intersection points between the moving tracks of the third reagent needle 623 and the fourth reagent needle 624 and the circle where the center of the bottle mouth of the second reagent bottle is located;

[0078] The angle between the center of the same bottle mouth and the corresponding two intersection points is greater than 60°.

[0079] During implementation, the first reagent bottle and the second reagent bottle are used to contain the first reagent and the second reagent, respectively. Since within one cycle, both reagent needles need to aspirate liquid from the reagent disk, for example, the first reagent needle 621 and the second reagent needle 622 both need to aspirate the first reagent from the first reagent bottle, or the third reagent needle 623 and the fourth reagent needle 624 both need to aspirate the second reagent from the second reagent bottle. Therefore, in the traditional solution, the reagent disk needs to rotate twice within one cycle, resulting in a large rotation distance of the reagent disk.

[0080] The present application designs that the moving track of each reagent needle and the circle where the center of the bottle mouth of the corresponding reagent bottle is located have two intersections, that is, the moving track of the first reagent needle 621 and the circle where the center of the bottle mouth of the first reagent bottle is located have two intersections, and the angle between these two intersections and the center of the bottle mouth of the first reagent bottle is a; similarly, the moving track of the second reagent needle 622 and the circle where the center of the bottle mouth of the first reagent bottle is located have two intersections, and the angle between these two intersections and the center of the bottle mouth of the first reagent bottle is also a; the moving track of the third reagent needle 623 and the circle where the center of the bottle mouth of the second reagent bottle is located also have two intersections, and the angle between these two intersections and the center of the bottle mouth of the second reagent bottle is a; the moving track of the fourth reagent needle 624 and the circle where the center of the bottle mouth of the second reagent bottle is located also have two intersections, and the angle between these two intersections and the center of the bottle mouth of the second reagent bottle is a, and the above angle a is greater than 60°. Through the above arrangement, the distance of the reagent disk rotation can be reduced, the liquid addition time can be shortened, and the test efficiency can be improved.

[0081] In some optional embodiments, the detection assembly includes a scattering optical module 510 and a transmissive optical module 520;

[0082] The scattering optical module 510 is used to irradiate the mixed solution in the reaction cup to form scattered light, and receive the scattered light for detection;

[0083] The transmission optical module 520 is used to irradiate the mixed solution in the reaction cup to form transmission light, and receive the transmission light for detection.

[0084] In implementation, the scattering optical module 510 is used for scattered light analysis and detection, and the transmission optical module 520 is used for transmitted light analysis and detection. Both the scattering optical module 510 and the transmission optical module 520 include a light source and a detection element, wherein the light source is used to emit light to the reaction cup, and after the light is irradiated to the mixed liquid in the reaction cup, scattered light or transmitted light is formed, which is received by the corresponding detection element. By setting two light detection functions, scattered light detection and transmitted light detection are realized respectively, thereby improving the detection accuracy.

[0085] In some optional embodiments, the scattering optical module 510 and the transmission optical module 520 are both disposed on the front side of the stage 100 .

[0086] During implementation, the scattering optical module 510 and the transmission optical module 520 are arranged close to the reaction disk 200, and the scattering optical module 510 and the transmission optical module 520 are located on the front side of the carrier 100, that is, the scattering optical module 510 and the transmission optical module 520 are close to the front end of the sample analyzer, so that the user can contact the scattering optical module 510 and the transmission optical module 520 from the front end of the sample analyzer, and then replace the light source lamp of the scattering optical module 510 and the transmission optical module 520.

[0087] In some optional embodiments, the sample analyzer provided by the present application further includes a reagent stirring module 700 and a sample stirring module 800;

[0088] The reagent stirring module 700 and the sample stirring module 800 are disposed on the stage 100 and are located on both sides of the transmission optical module 520 , respectively.

[0089] During implementation, both the reagent stirring module 700 and the sample stirring module 800 are provided with stirring rods, wherein the stirring rod of the reagent stirring module 700 is used to stir the reagent, and the stirring rod of the sample stirring module 800 is used to stir the sample. The reagent stirring module 700 and the sample stirring module 800 are respectively arranged on both sides of the transmission optical module 520, that is, the reagent stirring module 700 and the sample stirring module 800 can also be arranged close to the front end of the sample analyzer, so that the user can conveniently maintain the stirring rod from the front end of the sample analyzer.

[0090] In some embodiments, the transmission optical module 520 is located between the reagent stirring module 700 and the sample stirring module 800, the scattering optical module 510 and the transmission optical module 520 are spaced apart, and the light collection positions of the scattering optical module 510 and the transmission optical module 520 are spaced apart by a number of cup (reaction cup) positions, for example, 35 to 45 cup positions, preferably 41 (the number of cup positions in one cycle of rotation of the reaction disk 200) cup positions.

[0091] In some optional embodiments, the sample analyzer further includes a cleaning mechanism 900 installed on the carrier 100 , and the cleaning mechanism 900 is used to clean the reaction cup.

[0092] During implementation, the cleaning mechanism 900 is disposed on the carrier 100 and close to the rear end of the sample analyzer. Specifically, the cleaning mechanism 900 can be disposed between the sample needle and the stirring module, so that the modules and components on the carrier 100 are compact and reasonable in structure.

[0093] In some embodiments, the entire layout of the sample analyzer can be adjusted in a left-right mirrored manner. For example, the first reagent tray 310 and the second reagent tray 320 are located on the left side of the reaction tray 200. The first reagent tray 310 and the second reagent tray 320 can also be set on the right side of the reaction tray 200 without limitation.

[0094] In implementation, the test sequence of the sample analyzer provided by the present application is as follows: Figure 2 As shown, the reaction disk 200 stops once and rotates once per cycle. When the reaction disk 200 stops, corresponding operations are performed, such as the reagent needle adds reagent to the reaction disk 200, the sample needle adds sample to the reaction disk 200, the cleaning mechanism 900 cleans the reaction cup, the reagent stirring module 700 and the sample stirring module 800 perform stirring, and light measurement is performed during the rotation of the reaction disk 200. In order to ensure that light measurement is started only after the first reagent is added, the transmission optical module 520 performs light measurement (P1-P33) in a cycle after the first reagent is added. The scattering optical module 510 can only perform light measurement (SP1-SP33) in the cycle after the first reagent is added, so the scattering optical module 510 can only be arranged at the position between the fourth reagent needle 624 and the sample stirring module 800, and is separated from the light-collecting position of the transmission optical module 520 by 41 cup positions.
