Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of medical detection, and in particular is a blood routine and immunochromatography combined detection reagent card. Background Art
[0002] Routine blood tests usually include 25 indicators, mainly including three-category or five-category white blood cell counts, red blood cell counts, platelet counts and hemoglobin concentrations. Immunochromatographic tests mainly include fluorescent immunochromatographic tests such as CRP and SAA and colloidal gold tests for influenza A and influenza B.
[0003] At present, routine blood tests usually require the use of a blood cell analyzer. Traditional blood analyzer detection methods include electrical impedance method and sheath flow scattering method, which have the advantages of fast detection speed and accuracy, but have the disadvantages of requiring maintenance of the liquid circuit, high instrument cost and large size. With the implementation of the tiered diagnosis and treatment policy, more and more grassroots medical institutions such as clinics, health centers, dental clinics and beauty hospitals have more demand for routine blood tests. However, grassroots medical institutions have the characteristics of small sample size, lack of professional testing personnel, and tight laboratory space, which makes traditional blood analyzers unable to meet their needs.
[0004] The single-portion blood analyzer based on POCT (timely diagnosis) can perfectly meet the needs of primary medical institutions. It has the characteristics of no liquid path, maintenance-free, no pollution, small size and low instrument cost. There are two principles of blood analyzers based on POCT technology. One is the single-portion electrical impedance method. The gem micropores are made into plastic parts through mold injection molding, which become disposable consumables, and then installed between the two electrodes of the reagent card. The blood cell categories and quantities are counted by detecting the changes in the current pulse when the blood cells flow through the micropores. The principle is consistent with the traditional Coulter method. However, this method can only achieve three-classification detection of white blood cells, and because the assembly of micropores and electrodes is relatively complicated, the cost of single-portion reagent card consumables is high, which is difficult for customers to accept, and there is a risk of micropore blockage. The other is the single-portion image analysis method. After the cells are hemolyzed and stained, the processed samples are added to a cavity with a height of 100-200 microns, and photographed after precipitation, and then the classification and statistics are automatically completed by the image algorithm. The image analysis method has the advantages of low consumables cost and the ability to perform five classifications of white blood cells. The current image analysis-based instruments all manually process samples, add samples and cell sedimentation, and most of them only perform image photography of white blood cells. In addition, routine blood tests are usually combined with immune tests at the same time, so that clinical diagnosis can be better performed on whether the patient is infected with bacteria or viruses.
[0005] At present, POCT blood analysis instruments perform blood routine test and immune test separately. Patent with publication number CN111912766A proposes a test card for combined immune test and cell test. The reagent card disclosed in the patent requires manual sample processing and sample addition, and can only perform white blood cell test, not a complete blood routine test. In clinical evaluation, only white blood cell test has no clinical significance. Moreover, when calculating immune parameters such as CRP / SAA, the real hematocrit whole blood parameter is not used, and the theoretical set value is used. The result obtained will be different from the actual hematocrit value of special population, resulting in erroneous test results. Summary of the invention
[0006] The object of the present invention is to provide a blood routine test and immunochromatography combined detection reagent card to solve the above-mentioned problems in the prior art.
[0007] Provide a blood routine and immunochromatography combined detection reagent card, including:
[0008] The reagent card body includes a detection and counting area, a reagent filling area and a sampling area. The sampling area is used to accommodate samples and pre-dilution of samples. The reagent filling area is used for sample processing and dilution. The detection and counting area includes a red blood cell counting square groove, a white blood cell counting square groove and a platelet counting square groove.
[0009] This design integrates multiple blood processing and testing functions into one reagent card, which can perform routine blood tests and immunochromatography tests at the same time, simplifying the testing process, improving the adaptability of primary medical institutions to routine blood tests, and reducing equipment costs.
[0010] As a further embodiment of the present invention: it also includes a quantitative sampler, the sampling area includes a sampling hole, the quantitative sampler is detachably connected to the reagent card body, and the quantitative sampler is used to inject the sample into the sampling hole. This design allows the sampling process to control the sample volume and improves the accuracy of the test. Since the quantitative sampler can be separated from the reagent card, the convenience and reliability of the operation are improved, which meets the rapid detection requirements of the POCT device.
[0011] As a further embodiment of the present invention: the quantitative sampler is penetrated by a discharge hole. The discharge hole on the quantitative sampler can be used in conjunction with a TIP head. The hollow straw of the TIP head automatically sucks the sample into the tube by capillary force, and the TIP head is inserted into the discharge hole. The instrument's electric pipette pump provides power to discharge the sucked sample into the sampling hole below. Then, the TIP head absorbs a certain volume of diluent, aligns it with the discharge hole, and discharges the diluent by air pressure. The diluent enters the sampling hole from the discharge hole, flushing out the sample in the hollow capillary, and repeats this process many times until it is flushed clean.
[0012] As a further embodiment of the present invention: the sampling area includes a sample adding hole. The sample adding hole is used to directly add venous blood, and when venous blood has been collected, it is used to store the blood sample transferred from the blood collection tube.
[0013] As a further embodiment of the present invention: a counting area cover is provided on the detection counting area. The counting area cover can seal the counting area to prevent external pollutants from interfering with the detection process, facilitate microscope observation, and ensure the accuracy of the test.
[0014] As a further embodiment of the present invention: the bottoms of the square grooves for red blood cell counting, white blood cell counting and platelet counting are provided with light-transmitting areas for arranging microscope illumination light sources.
[0015] As a further embodiment of the present invention: the square grooves for red blood cell counting, white blood cell counting and platelet counting are bonded to the counting area cover plate by ultraviolet light curing glue. The closed design of the counting area cover plate helps to prevent the sample from overflowing during the detection process.
[0016] As a further embodiment of the present invention: the counting area cover plates on the red blood cell counting square trough, the white blood cell counting square trough and the platelet counting square trough are integrally formed. The integrally formed structure reduces the number of parts in the assembly process and improves assembly efficiency. The closed design of the counting area cover plate helps prevent the sample from overflowing during the detection process.
[0017] As a further embodiment of the present invention: the counting area cover is provided with a red blood cell detection cavity exhaust hole connected to the red blood cell counting square groove and a red blood cell reaction liquid loading groove, the counting area cover is provided with a white blood cell detection cavity exhaust hole connected to the white blood cell counting square groove and a white blood cell reaction liquid loading groove, and the counting area cover is provided with a platelet detection cavity exhaust hole connected to the platelet counting square groove and a platelet reaction liquid loading groove.
[0018] The liquid adding groove is located at one end of the square groove and is used to draw the liquid to flow in the detection cavity of the square groove. The exhaust hole is located at the other end of the square groove and is used to exhaust air to balance the air pressure in the detection cavity of the square groove, so that the liquid can flow smoothly.
[0019] As a further embodiment of the present invention, the reagent filling area includes a hemoglobin processing liquid chamber, and the side wall of the reagent card body opposite to the hemoglobin processing liquid chamber is provided with a hemoglobin detection light-transmitting surface. The hemoglobin detection light-transmitting surface can be used to perform absorbance detection on the sample in the hemoglobin processing liquid chamber.
[0020] As a further embodiment of the present invention: the reagent filling area includes a red blood cell processing liquid chamber, a second diluent chamber, a first diluent chamber, a platelet processing liquid chamber, a red blood cell diluent chamber, an inflammation processing liquid chamber, a saccharification processing liquid chamber, a white blood cell processing liquid chamber and a white blood cell reaction chamber. The reagent filling area includes a plurality of different chambers, which can provide a special processing liquid for the sample. This multi-chamber design ensures that the sample is scientifically and reasonably processed during the detection process, and can be tested for various components separately, thereby realizing the combined detection of blood routine and immune detection, and improving the comprehensiveness and accuracy of the detection.
[0021] As a further embodiment of the present invention: a mounting portion is provided at the bottom of the reagent card body, and the mounting portion is used to ensure that the reagent card is stably placed when in use.
[0022] Compared with the prior art, the present invention has the following beneficial effects:
[0023] 1. It realizes the five groups of neutrophils, lymphocytes, monocytes, eosinophils and basophils in white blood cells, and cooperates with other necessary blood routine parameters and CRP, SAA, glycosylated hemoglobin and other parameters to promote the promotion of grassroots POCT instruments.
[0024] 2. Convenient operation for users. One reagent card plus an immunochromatography card can automatically complete the combined test of blood routine and immunochromatography items without additional sample dilution. The all-in-one design reduces the detection cost of a single card. Combined with microscopy and image recognition technology, the instrument is liquid-free and maintenance-free, which meets the application requirements of POCT usage scenarios and reduces instrument and detection costs.

In addition, the drawings and the following description are provided to enable those skilled in the art to fully understand the present invention and are not intended to limit the subject matter described in the claims.
[0033] See also Figure 1-Figure 3As shown, the blood routine and immunochromatography combined detection reagent card in the embodiment of the present invention includes a reagent card body 1, and the reagent card body 1 includes a detection and counting area, a reagent filling area and a sampling area. The sampling area is used to accommodate samples and pre-dilution of samples, the reagent filling area is used for sample processing and dilution, and the detection and counting area includes a red blood cell counting square groove 115, a white blood cell counting square groove 116 and a platelet counting square groove 117.
[0034] There are three counting windows in total, namely, the square slot 115 for red blood cell counting, the square slot 116 for white blood cell counting, and the square slot 117 for platelet counting. The square slots are separated from each other to achieve independence. A counting area cover plate 3 is provided on the detection and counting area. The counting area cover plate 3 is made of a transparent material, and various holes are designed to guide the liquid to the corresponding square slot area, and then perform microscopic photography and immune detection. A light-transmitting area is provided at the bottom of the square slot 115 for red blood cell counting, the square slot 116 for white blood cell counting, and the square slot 117 for platelet counting, where a microscope illumination light source can be arranged.
[0035] The quantitative sampler 2 is used to collect quantitative samples and discharge the samples into the sampling hole 107. The quantitative sampler 2 is penetrated by a discharge hole 201, and the discharge hole 201 on the quantitative sampler 2 can be used in conjunction with the TIP head. The hollow straw of the quantitative sampler 2 automatically sucks the sample into the tube by capillary force, and the TIP head is inserted into the discharge hole 201. The instrument's electric pipette pump provides power to discharge the sample sucked by the quantitative sampler 2 into the sampling hole 107 below. After the sample of the quantitative sampler 2 is discharged, it is installed on the sampling hole 107 and fixed by the groove 118. The TIP head absorbs a certain volume of diluent, then aligns it with the discharge hole 201, and discharges the diluent by air pressure. The diluent enters from the discharge hole 201 and flushes out the sample in the hollow capillary of the quantitative sampler 2, and repeats several times until it is flushed clean.
[0036] The sampling area includes a sample addition hole 108, which is used to store blood samples transferred from the blood collection tube to the reagent card for testing when venous blood has been collected. The sample addition hole 108 is suitable for directly adding venous blood therein, and does not require the quantitative sampler 2 for quantitative blood collection.
[0037] A counting area cover plate 3 is provided on the detection counting area. The counting area cover plate 3 is made of transparent material and is used to stabilize the samples in each square groove, prevent external contamination, and create conditions for microscope observation.
[0038] The counting area cover plate 3 and the reagent card body 1 can be bonded by ultraviolet light curing glue. The counting area cover plate 3 on the red blood cell counting square groove 115, the white blood cell counting square groove 116 and the platelet counting square groove 117 are integrally formed. The counting area cover plate 3 is provided with a red blood cell reaction solution loading groove 304, a white blood cell reaction solution loading groove 305 and a platelet reaction solution loading groove 306 which are connected to the corresponding square grooves. The reaction solution to be tested can be siphoned to the detection cavity area of the three corresponding square grooves through the loading grooves. The detection cavity of the square groove is formed by being recessed inward.
[0039] The counting area cover plate 3 is provided with a red blood cell detection chamber exhaust hole 301, a white blood cell detection chamber exhaust hole 302, and a platelet detection chamber exhaust hole 303 which are connected to the corresponding square grooves. The three detection chamber areas have independent exhaust holes. When the reaction liquid flows into the sample loading slot, the gas is discharged through the exhaust hole located at the other end of the counting area cover plate 3 to balance the internal air pressure, so as to realize the flow of the traction liquid in the detection chamber.
[0040] The three detection areas of the red blood cell counting slot 115, the white blood cell counting slot 116 and the platelet counting slot 117 correspond to the following three tests respectively:
[0041] The red blood cell counting square slot 115 is mainly used for measuring red blood cell parameters;
[0042] The white blood cell counting square slot 116 is mainly used for total white blood cell count and five-category grouping calculation of neutrophils, lymphocytes, monocytes, eosinophils, and basophils;
[0043] The platelet counting slot 117 is mainly used for measuring platelet parameters.
[0044] The red blood cell treatment liquid chamber 102, the white blood cell treatment liquid chamber 112, the red blood cell dilution liquid chamber 109, the platelet treatment liquid chamber 105, the diluent chamber 104, the diluent chamber 2 103, the hemoglobin treatment liquid chamber 106, the inflammation treatment liquid chamber 110, and the saccharification treatment liquid chamber 111 are all reagent filling areas and need to be sealed with a heat-sealed film. The white blood cell reaction chamber 114, the sample addition hole 108, and the sampling hole 107 are all non-filling areas.
[0045] The bottom of the reagent card body 1 is provided with a mounting portion 101 , which may specifically be a T-slot structure, so as to facilitate fixing the detection reagent card in the detection instrument.
