Description

Technical Field

[0001] The present application relates to the technical field of medical consumables, and in particular to a detection consumable. Background Art

[0002] POCT (point-of-care testing) refers to clinical and bedside testing performed at the patient's side. It provides rapid results by performing analysis immediately at the point of collection, eliminating the complex sample transfer process to a laboratory. POCT typically involves performing routine blood tests on a patient's blood sample. The results analyze changes in blood cell count and morphology to determine blood status and diagnose diseases.

[0003] In a routine blood test, the more common and important test items include red blood cell count (RBC), white blood cell count (WBC), platelet count (PLT) and hemoglobin (HGB) determination. The pretreatment of blood samples is generally divided into two types: manual pretreatment by medical staff and automatic pretreatment by the detection instrument. For automatic pretreatment, the existing detection consumables integrate the pretreatment module, counting module and hemoglobin colorimetric detection module to form an integrated structure, and the pipetting module on the detection instrument is used to dilute, mix, transfer and other pretreatments of the sample contained in the detection consumables. After the pretreatment is completed, the detection module is used to count and detect the pretreated sample and determine the hemoglobin.

[0004] For the detection consumables with an integrated structure, all the detection items need to be completed before the detection consumables can be replaced to detect the next sample. Therefore, during the sedimentation and counting process of the current sample, the pipetting module cannot pre-process the next sample, affecting the pre-processing efficiency. In addition, the overall structure of the detection consumables with an integrated structure is larger, which makes the flatness of the counting module easily affected, thereby affecting the focusing efficiency of the detection module and increasing the number of photos taken.

[0035] See Figure 1-3 As shown, the present application provides a detection consumable, which is applied to a POCT blood cell analyzer.

[0036] The test consumables include a reagent kit 10 and a test card 20, each independent of the other. The test kit 10 is configured with a sample dilution position 111 and a reagent storage position, each separated from the other. The sample dilution position 111 is used to receive the original blood sample to be diluted, and the reagent storage position is used to store reagents, which are mixed and reacted with the diluted original blood sample to obtain the sample to be tested. The test card 20 is configured with a detection channel, which is used to receive the sample to be tested so that it can be detected by the detection module in the POCT blood cell analyzer.

[0037] By arranging the test kit 10 and the test card 20 independently from each other, so that the test kit 10 and the test card 20 are loaded into the POCT blood cell analyzer separately, the independent test card 20 has a simpler structure than the integrated test card 20 and the test kit 10, and does not require a mutual connection and matching structure, thereby reducing the difficulty and cost of processing, and avoiding the influence of the test kit 10 on the flatness of the test card 20 when the test card 20 and the test kit 10 are matched, thereby improving the detection efficiency and detection accuracy of the POCT blood cell analyzer for the first sample to be tested in the test card 20. In addition, when one of the independent test card 20 and the test kit 10 is unusable, only the unusable one can be replaced and the other can continue to be used, thereby avoiding the simultaneous discarding of the integrated test card 20 and the test kit 10.

[0038] Furthermore, the reagent kit 10 includes a box body 11 and an operating unit 12. The operating unit 12 is connected to one side of the box body 11 along a first direction. The box body 11 is configured to form the sample dilution position 111 and the reagent storage position. The operating unit 12 is used to operate the reagent kit 10 in and out of the POCT hematology analyzer.

[0039] Furthermore, the sample dilution station 111 includes a first sample dilution pool 1111 and a second sample dilution pool 1112. The second sample dilution pool 1112 is spaced apart from the first sample dilution pool 1111. The first sample dilution pool 1111 is used to receive a sample diluted by flushing, and the second sample dilution pool 1112 is used to receive a sample diluted by pipetting.

[0040] Furthermore, the first sample dilution pool 1111 includes a first receiving cavity 11111 and a second receiving cavity 11113 that are interconnected, and the second receiving cavity 11113 is located between the first receiving cavity 11111 and the second sample dilution pool 1112 along the first direction.

[0041] Further, see Figure 4-5 As shown, the first receiving cavity 11111 is used for inserting the first sampling device 200, and the first sampling device 200 dilutes the sample in the first sample dilution pool 1111 by flushing. In this embodiment, the first sampling device 200 is a blood sampling device.

[0042] See also Figure 6-7 As shown, the second receiving cavity 11113 is used for inserting the second sampling device 300. The sample received in the second sampling device 300 is transferred to the second sample dilution reservoir 1112 for dilution by a pipetting device. In this embodiment, the second sampling device 300 is an EP tube.

[0043] By providing the first sample dilution pool 1111 and the second sample dilution pool 1112 , the test kit 10 is compatible with two sample dilution methods, thereby making the detection consumables compatible with a variety of different sampling devices.

[0044] Furthermore, the first cavity bottom 11112 of the first receiving cavity 11111 is inclined toward the second cavity bottom 11114 of the second receiving cavity 11113 , so that the second cavity bottom 11114 is lower than the first cavity bottom 11112 in the vertical direction.

[0045] The reagent kit 10 is provided with a fixing structure 13 outside the first receiving cavity 11111. When the blood collection device is fixed to the fixing structure 13, the blood collection device at least partially extends into the first receiving cavity 11111. After the diluent is injected from the blood collection device, the injected diluent enters the first receiving cavity 11111 together with the original blood sample collected in the blood collection device and flows along the inclined first cavity bottom 11112 into the second receiving cavity 11113.

[0046] In order to flush the original blood sample collected in the blood collector into the first sample dilution pool 1111 as much as possible, and to fully mix the original blood sample and the diluent, the mixture of the original blood sample and the diluent flushed into the second receiving chamber 11113 can be sucked out and then injected into the first sample dilution pool 1111 from the blood collector.

[0047] Furthermore, the first sample dilution pool 1111 is located between the operating portion 12 and the second sample dilution pool 1112 along the first direction.

[0048] For further information, please refer to Figure 1-3 As shown, the reagent storage position includes at least one of a red blood cell reagent receiving chamber 1121 , a dye receiving chamber 1122 , and a hemoglobin reagent receiving chamber 1123 .

[0049] The detection card 20 includes at least one of a red blood cell detection channel 21 , a white blood cell detection channel 22 , and a platelet detection channel 23 .

[0050] In one embodiment, the reagent storage location includes the mutually independent red blood cell reagent receiving chamber 1121, the dye receiving chamber 1122, and the hemoglobin reagent receiving chamber 1123. The red blood cell reagent receiving chamber 1121 receives red blood cell reagent, the dye receiving chamber 1122 receives dye, and the hemoglobin reagent receiving chamber 1123 receives hemoglobin reagent.

[0051] The detection card 20 includes the red blood cell detection channel 21 , the white blood cell detection channel 22 , and the platelet detection channel 23 , which are independent of each other.

[0052] Furthermore, the red blood cell detection channel 21 has a first sample loading port 211, the white blood cell detection channel 22 has a second sample loading port 221, and the platelet detection channel 23 has a third sample loading port 231. The first sample loading port 211, the second sample loading port 221, and the third sample loading port 231 are arranged sequentially along the second horizontal direction and are located on the same side of the detection card 20 along the first direction.

[0053] Furthermore, the red blood cell detection channel 21 also includes a first air outlet 213 and a first detection area 212. The first detection area 212 is connected along the first horizontal direction between the first sample loading port 211 and the first air outlet 213. The first air outlet 213 is used to allow air in the red blood cell detection channel 21 to be exhausted, so that the red blood cell sample to be tested enters the red blood cell detection channel 21 from the first sample loading port 211 and moves smoothly to the first detection area 212 for uniform sedimentation.

[0054] The leukocyte detection channel 22 further includes a second air outlet 223 and a second detection area 222. The second detection area 222 is connected along the first horizontal direction between the second sample loading port 221 and the second air outlet 223. The second air outlet 223 is used to allow air in the leukocyte detection channel 22 to be exhausted, thereby facilitating the leukocyte sample to be tested to enter the leukocyte detection channel 22 from the second sample loading port 221 and smoothly move to the second detection area 222 for uniform sedimentation.

[0055] The platelet detection channel 23 further includes a third air outlet 233 and a third detection zone 232. The third detection zone 232 is connected along the first horizontal direction between the third sample loading port 231 and the third air outlet 233. The third air outlet 233 is used to allow air within the platelet detection channel 23 to be exhausted, thereby facilitating the platelet sample to enter the platelet detection channel 23 from the third sample loading port 231 and smoothly move to the third detection zone 232 for uniform sedimentation.

[0056] The samples to be tested that are respectively deposited in the first detection area 212 , the second detection area 222 , and the third detection area 232 are counted and detected by the microscope unit of the POCT blood cell analyzer based on the microscopic imaging method.

[0057] Specifically, the microscopic imaging method involves capturing images of each test area using a microscope unit, thereby obtaining multiple microscopic images of each test area. These captured microscopic images are then analyzed to obtain corresponding recognition results. These microscopic images can then be sorted to generate a test report based on the sorting results.

[0058] The box body 11 is structured to form a first cleaning chamber 113 , a second cleaning chamber 114 , a third cleaning chamber 115 , a white blood cell sample processing pool 116 , and a platelet sample processing pool 117 , which are independent of each other.

[0059] Furthermore, the first cleaning chamber 113 contains a first cleaning liquid, the second cleaning chamber 114 contains a second cleaning liquid, and the third cleaning chamber 115 contains a third cleaning liquid.

[0060] Furthermore, each of the reagent kits 10 also carries a pipette head 30. When the pipetting device starts to process the original blood sample in the current reagent kit 10, the pipetting device will first load the pipette head 30 in the reagent kit 10 and transfer each solution through the pipette head 30.

[0061] Furthermore, after the pipetting device transfers the first sample of the sample to be processed obtained after dilution into the red blood cell reagent receiving chamber 1121 through the pipetting head 30, and aerates and mixes it to obtain the red blood cell sample to be tested, and transfers the red blood cell sample to be tested to the red blood cell detection channel 21, the pipetting head 30 will move to the first cleaning chamber 113 to be cleaned by the first cleaning fluid to avoid the residual solution in the process of processing the red blood cell sample to affect the subsequent sample processing.

[0062] After the pipetting device transfers the second sample of the sample to be processed into the white blood cell sample processing pool 116 through the pipetting head 30, and transfers part of the dye solution into the white blood cell sample processing pool 116, it aerates and mixes to obtain the white blood cell sample to be tested. After the white blood cell sample to be tested is transferred to the white blood cell detection channel 22, the pipetting head 30 moves to the second cleaning chamber 114 to be cleaned with the second cleaning solution to prevent the residual solution in the process of processing the white blood cell sample to affect the subsequent sample processing.

[0063] After the pipetting device transfers the third sample of the sample to be processed into the platelet sample processing pool 117 through the pipetting head 30, and transfers part of the hemoglobin reagent into the platelet sample processing pool 117, it aerates and mixes to obtain the platelet sample to be tested. After the platelet sample to be tested is transferred to the platelet detection channel 23, the pipetting head 30 will move to the third cleaning chamber 115 for cleaning with the third cleaning liquid to avoid the residual solution in the process of processing the platelet sample to be tested affecting the subsequent sample processing.

[0064] Furthermore, the box body 11 has a packaging area, and the packaging area is located on a side of the sample dilution position 111 away from the operating portion 12 along the first direction.

[0065] Furthermore, the separately arranged red blood cell reagent receiving chamber 1121, the dye receiving chamber 1122, the hemoglobin reagent receiving chamber 1123, the first cleaning chamber 113, the second cleaning chamber 114 and the third cleaning chamber 115 are located in the packaging area, and their corresponding opening ends are sealed by the same heat-sealing film.

[0066] Preferably, the sealing ends corresponding to the red blood cell reagent receiving chamber 1121, the dye receiving chamber 1122, the hemoglobin reagent receiving chamber 1123, the first cleaning chamber 113, the second cleaning chamber 114 and the third cleaning chamber 115 respectively protrude at the same height on the surface of the box body 11, so that the sealing ends corresponding to the red blood cell reagent receiving chamber 1121, the dye receiving chamber 1122, the hemoglobin reagent receiving chamber 1123, the first cleaning chamber 113, the second cleaning chamber 114 and the third cleaning chamber 115 can be sealed by the same heat-sealing film.

[0067] Furthermore, in a top view of the reagent kit 10, the white blood cell sample processing reservoir 116 and the platelet sample processing reservoir 117 are disposed along the first direction on opposite sides of the second sample dilution reservoir 1112. This shortens the distance the pipette device travels when transferring the second sample from the first sample dilution reservoir 1111 or the second sample dilution reservoir 1112 to the white blood cell sample processing reservoir 116, and shortens the distance the pipette device travels when transferring the third sample from the first sample dilution reservoir 1111 or the second sample dilution reservoir 1112 to the platelet sample processing reservoir 117. This reduces the pipetting distance of the pipette device and improves pipetting efficiency.

[0068] Furthermore, the hemoglobin reagent receiving chamber 1123 is located at an end of the box body 11 away from the operating portion 12 along the first direction.

[0069] The cartridge body 11 is provided with a first light-transmitting area 11231 and a second light-transmitting area 11232 on opposite sides of the hemoglobin reagent receiving chamber 1123 along the second direction. The first light-transmitting area 11231 and the second light-transmitting area 11232 are at least partially aligned with each other, so that the hemoglobin sample to be tested contained in the hemoglobin reagent chamber can be detected by the absorbance detection device.

[0070] Furthermore, in the top view of the reagent kit 10 , the second direction and the first direction are perpendicular to each other.

[0071] Furthermore, the box body 11 is provided with a first clamping arm 14 and a second clamping arm 15 on opposite sides of the hemoglobin reagent receiving chamber 1123 along the first direction. The first clamping arm 14 and the second clamping arm 15 are used to clamp the reagent kit 10 to the POCT blood cell analyzer.

[0072] Furthermore, the first card arm 14 and the second card arm 15 are symmetrically arranged along the first direction, and the first card arm 14 and the second card arm 15 are both elastic card arms, so that when the first card arm 14 and the second card arm 15 apply a certain external force to the operating part 12, the reagent kit 10 can be unloaded from the POCT blood cell analyzer and the reagent kit 10 can be loaded onto the POCT blood cell analyzer.

[0073] Furthermore, a dry fluorescent sample processing pool 118 and a pipette head placement position 119 are formed on the box body 11 . The dry fluorescent sample processing pool 118 and the pipette head placement position 119 are arranged side by side along the second direction and are located between the operating part 12 and the first sample dilution pool 1111 .

[0074] The pipetting head placement position 119 is used to place the pipetting head 30 , and the dry fluorescence sample processing pool 118 is used to pre-process the dry fluorescence sample to be tested.

[0075] After all the test items involved in the current reagent kit 10 are completed, the pipetting head 30 on the current pipetting device will be unloaded into the dry fluorescent sample processing pool 118. Thus, the dry fluorescent sample processing pool is used to accommodate the discarded pipetting heads 30.

[0076] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0077] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0078] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
