[0031] The present invention provides a specific protein testing system for a hematology analyzer.

[0032] Reference Figures 1 to 6In one embodiment of the present invention, the specific protein testing system of the blood cell analyzer includes: an analyzer body 1, a reagent processing module 2, a signal acquisition module 3, a storage module 4 and a sampling module 5. The reagent processing module 2 is provided in the analyzer body 1, and the reagent processing module 2 is provided with a reaction cup 21; the reaction cup body is formed with a reaction chamber 211, and the cavity wall portion of the reaction chamber 211 is provided as a transparent light detection wall 212, and the thickness of the transparent light detection wall 212 is thinner than the thickness of other cavity walls; the signal acquisition module 3 is provided in the analyzer body 1, and is provided close to the reagent processing module 2, and the turbidity change in the reaction chamber 211 can be observed or detected through the transparent light detection wall 212; the storage module 4 is provided in the analyzer body 1, and the storage module 4 is provided with a storage container; a sampling module 5 is movably provided on the analyzer body 1, and the sampling module 5 includes a movable component 51 and a second sampling needle 52, and the second sampling needle 52 can use the movable component 51 to dispense the second sample from the storage module 4 to the reaction cup 21; the reagent processing module 2 includes a pre-mixing module 23, and the reaction cup 21 is movably provided on the pre-mixing module 23, and the pre-mixing module 23 reciprocates the reaction cup 21 between the lower needle position of the first sampling needle and the lower needle position of the second sampling needle 52.

[0033] The technical solution of the present invention uses a reagent processing module 2 to insert the first sample collected by the first sampling needle and the second sample collected by the second sampling needle 52 into the reagent processing module 2 for mixing, thereby obtaining the required test sample. Specifically, the reaction cup 21 is used to hold samples, reagents and other liquids involved in the reaction. The cavity wall portion of the reaction chamber 211 is configured as a transparent optical detection wall 212. The signal acquisition module 3 obtains the presence or absence of the test sample in the reaction cup 21 and various parameters of the test sample through the transparent optical detection wall 212 of the reaction cup 21. The storage module 4 is pre-placed with the second sample, and the second sampling needle 52 can directly take out the second sample from the storage module 4 and add it into the reaction cup 21, so as to achieve faster mixing of the first sample and the second sample, thereby improving the mixing efficiency of the sample in the analyzer and also improving the efficiency of the analyzer detection.

[0034] Furthermore, the reaction chamber 211 has an upwardly disposed liquid inlet 213 and a downwardly disposed liquid outlet; the walls of the reaction chamber 211 are configured to gradually taper downward, and the walls of the reaction chamber 211 are connected to the sidewalls of the liquid outlet via arcuate sidewalls. In this embodiment, the reaction chamber 211 has an upwardly disposed liquid inlet 213, and a sampling needle injects a sample into the reaction chamber 211 from the top of the reaction cup 21 for mixing. The reaction chamber 211 has a downwardly disposed liquid outlet. When the liquid in the reaction chamber 211 is sufficient or excessive, the reaction cup 21 can discharge the excess sample through the liquid outlet. The analyzer can discharge excess sample without removing the reaction cup 21, making the entire device more convenient and simple to use.

[0035] Furthermore, the cuvette 21 includes an elastic retaining rib 215, one end of which is connected to the outer circumference of the cuvette 21 body and the other end of which extends away from the cuvette 21 body. The elastic retaining rib 215 is formed with at least one latching protrusion on a side facing away from the cuvette body. In one embodiment, the cuvette 21 is provided with the elastic retaining rib 215, and the cuvette 21 is removably attached to the reagent processing module 2 via the spring retaining rib. The removable attachment of the cuvette 21 facilitates easy replacement of the cuvette 21, ensuring cleanliness during use and preventing contamination between different samples. However, this embodiment is not limited to having only one latching protrusion; two, three, or more latching protrusions may be provided. One of the latching protrusions secures the cuvette 21 in the reagent processing module 2, while the other latching protrusions act as friction-enhancing structures. During removal of the cuvette 21, the other latching protrusions enhance friction with the hand, facilitating removal of the cuvette 21.

[0036] Furthermore, a stirring vibration member 53 is provided at the connection position between the second sampling needle 52 and the movable assembly 51. To facilitate mixing and testing the sample in the reaction cup 21, a stirring vibration member 53 is provided at the connection position between the second sampling needle 52 and the movable assembly 51. The stirring vibration member 53 vibrates the second sampling needle 52 to stir the sample in the reaction cup 21.

[0037] Furthermore, the movable assembly 51 includes an elastic member, to which one end of the second sampling needle 52 is connected. The elastic member is also provided with a sensor, which is electrically connected to the movable assembly 51. When the second sampling needle 52 strikes the needle, the elastic member is compressed, triggering the sensor to control the movable assembly 51 to stop moving. Specifically, when the second sampling needle 52 strikes the needle, the elastic member is compressed and elastically deforms. The sensor, sensing this elastic deformation, controls the movable assembly 51 to stop moving, thereby preventing damage to the second sampling needle 52.

[0038] Further, refer to Figure 1 The storage module 4 is divided into a normal temperature storage area 41 and a cold storage area 42; the normal temperature storage area 41 includes a CRP (C-reactive protein C-reactive protein) buffer tank, a treatment liquid tank and an SAA (serum amyloid protein) buffer tank; the cold storage area 42 includes a CRP latex tank and an SAA latex tank. The storage module 4 is provided with a normal temperature storage area 41 and a cold storage area 42, which is conducive to storing reaction reagents under different environmental requirements and facilitates the second sampling needle 52 to directly obtain reagents. It should be understood that in this embodiment, the second sample includes CRP buffer, SAA buffer, treatment liquid, CRP latex and SAA latex.

The rotational motion mechanism includes a rotatable rotating disk 513-1, which is connected to the horizontal motion mechanism 514.

The horizontal slider 514-3 is mounted on the third synchronous belt 514-5. The second sampling needle 52 is fixed to the horizontal slider 514-3. In this embodiment, the movable assembly 51 also includes a rotating rod 512-5.

The horizontal motor 514 - 1 can rotate as the rotating rod 512 - 5 rotates, and can rise and fall as the rotating rod 512 - 5 rises and falls.

[0041] Further, refer to Figure 3 and Figure 4The reagent processing module 2 includes a reaction structure 22; the reaction structure 22 includes a cuvette mounting base 221. The cuvette mounting base 221 is fixed to the analyzer body 1 and defines a first mounting groove 222. The notch of the first mounting groove 222 faces upward, and at least one cuvette 21 is detachably mounted in the first mounting groove 222.

Specifically, the laser device detects the background value of the cuvette 21 through the signal acquisition hole 223 on the cuvette mounting base 221 and the transparent optical detection wall 212 of the cuvette 21. This background value detection by the laser device allows vacant cuvettes 21 to be screened for subsequent liquid mixing testing by the sampling needle.

One end of the sliding guide rail 236 is a pre-mixing position 6 for the second sampling needle 52 to transport and mix the second sample. Specifically, the first sample is added from the sample position 7 into the reaction cup 21 of the pre-mixing module 23 via the first sampling needle.

The first sampling needle stirs and mixes the reaction cup 21 located in the pre-mixing position 6 via the stirring vibration member 53.

[0054] After signal acquisition is completed, the pre-diluted sample in the reaction cup 21 of the sliding block and the mixed solution in the reaction cup 21 of the reaction structure 22 are discharged and cleaned, and the first sampling needle and the second sampling needle 52 are cleaned, thereby completing a CRP or SAA test.

[0055] It should be understood that when the second sampling needle 52 in the detection method of the specific protein test system of the hematology analyzer performs CRP testing or SAA testing, the order of adding liquids needs to strictly follow the order of buffer solution, emulsion, and pre-diluted sample, because the amount of buffer solution is larger, and the amount of emulsion and pre-diluted sample is tiny compared to the buffer solution. If the emulsion or pre-diluted sample is added first, the buffer solution subsequently sucked in by the second sampling needle 52 will push the previously sucked emulsion or pre-diluted sample upward instead of dissolving it in the buffer solution, and the final mixed liquid will not meet the detection standard.

[0056] The hematology analyzer specific protein testing system adopts an iterative testing method including:

[0057] The reaction cup mounting base is provided with at least a first reaction cup and a second reaction cup;

[0058] After the second sampling needle completes the mixing process of the mixed liquid in the first reaction cup, the first sampling needle and the second sampling needle are in an idle state during the process of complete mixing in the first reaction cup;

[0059] The second sampling needle in an idle state can mix the second reaction cup;

[0060] The movable laser device is provided with a signal collection period T. Every T time, the laser device can sequentially collect the turbidity value in the first reaction cup and / or the second reaction cup.

[0061] After using the iterative testing method, the testing speed of the design scheme of the present invention is greatly improved, and multiple reaction cups can be mixed in a short time.

[0062] refer to Figure 6 In one embodiment, the specific protein testing system of the blood cell analyzer also includes a waste liquid discharge liquid path and a sampling needle cleaning liquid path connected by pipelines. The cleaning structure includes a syringe, which is connected to the sampling needle, and the syringe injects a diluent into the sampling needle at a uniform speed to achieve the effect of cleaning the inner wall of the sampling needle. In addition, the sampling needle is inserted into the water bath to enable the system to clean the outer wall of the sampling needle. Furthermore, the reaction cup 21 can discharge the waste liquid accumulated in the reaction cup 21 through the liquid outlet 214 at the bottom. The coolant used for the tank body in the storage module 4 can also be discharged through the pipeline connected to the bottom of the tank body.

[0063] Specifically, in this embodiment, the waste liquid discharge liquid circuit is provided with a waste liquid pump and is connected to the reaction cup. The waste liquid pump discharges the waste liquid in the reaction cup to the specific protein testing system of the blood cell analyzer; the sampling needle cleaning liquid circuit includes a diluent storage device, a diluent pump, a syringe and a water bath. The diluent is injected from the diluent storage device via the diluent pump and the syringe from the second sampling needle into the water bath. The diluent can also be directly injected from the diluent storage device into the water bath by the diluent pump.

All equivalent structural transformations made using the contents of the present description and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
