Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a microcolumn gel card puncture structure and a blood type analyzer. Background Art

[0002] Microcolumn gel cards generally include several columns. The formula of gel added to the columns of microcolumn gel cards is different, and they can be used for different types of test items, for example, they can be used for blood typing, cross-matching, anti-human globulin and other experiments. Depending on the test items, the formula of gel in microcolumn gel cards is different. In addition, the number of columns in gel cards may be different for different test items. Microcolumn gel test cards are based on microcolumn gel technology. Its principle is that after adding the blood sample to the gel column, the gap of the gel in the card column has a molecular sieve effect, allowing only free red blood cells to pass through. After centrifugation in a centrifuge, if the red blood cells in the microcolumn gel that have not undergone agglutination reaction are deposited at the bottom of the card, it indicates a negative reaction. If the red blood cells are agglutinated, they cannot pass through the gel gap and are at the top or middle of the card, which is considered to be agglutinated, indicating a positive reaction.

[0003] Microcolumn gel cards are usually sealed with aluminum foil. During testing, the sealed aluminum foil needs to be punctured so that the sample can be added to the microcolumn gel card by the sample needle for testing. Currently, in the step of puncturing the aluminum foil on the surface of the microcolumn gel card, the existing puncture mode is usually to puncture the entire gel card or half of the gel card at the same time. Since the number of holes in the microcolumn gel card required for different experimental projects is different, the current puncture mode will result in a waste of microcolumn gel cards.

[0040] Microcolumn gel cards generally include several columns. The formula of gel added to the columns of microcolumn gel cards is different, and they can be used for different types of test items, for example, they can be used for blood typing, cross-matching, anti-human globulin and other experiments. Depending on the test items, the formula of gel in microcolumn gel cards is different. In addition, the number of columns in gel cards may be different for different test items. Microcolumn gel test cards are based on microcolumn gel technology. Its principle is that after adding the blood sample to the gel column, the gap of the gel in the card column has a molecular sieve effect, allowing only free red blood cells to pass through. After centrifugation in a centrifuge, if the red blood cells in the microcolumn gel that have not undergone agglutination reaction are deposited at the bottom of the card, it indicates a negative reaction. If the red blood cells are agglutinated, they cannot pass through the gel gap and are at the top or middle of the card, which is considered to be agglutinated, indicating a positive reaction.

[0041] Microcolumn gel cards are usually sealed with aluminum foil. During testing, the sealed aluminum foil needs to be punctured so that the sample can be added to the microcolumn gel card by the sample needle for testing. Currently, in the experimental process, the step of puncturing the aluminum foil on the surface of the microcolumn gel card usually involves puncturing the entire gel card or half of the gel card at the same time. Because different experimental projects require different numbers of microcolumn gel card holes, the current puncture mode will result in a waste of gel cards.

[0042] To solve the above problems, please refer to Figures 1 to 4 The utility model proposes a micro-column gel card puncture structure, which includes:

[0043] A tray 110, the tray 110 is used to hold the reagent card;

[0044] A first puncture assembly 120, the first puncture assembly 120 includes a first number of first puncture needles 121; and

[0045] The second puncture assembly 140 includes a second number of second puncture needles 141, and the first puncture needle 121 and the second puncture needle 141 are both used to puncture the surface of the reagent card;

[0046] The first amount is greater than the second amount;

[0047] When the number of surfaces of the reagent card to be punctured is the first number or an integral multiple of the first number, the first number of first puncture needles 121 are used for puncture;

[0048] When the number of surfaces of the reagent card to be punctured is the second number, the second number of second puncture needles 141 is used for puncture.

[0049] In this embodiment, while ensuring the original puncture structure, that is, the first puncture component 120, a second puncture component 140 that can move independently is designed, wherein the number of second puncture needles 141 can be 1, 2 or 3. According to the number of surfaces that need to be punctured according to experimental requirements, that is, the number of microcolumn gel card holes, the first puncture component 120 or the second puncture component 140 is selected for puncture, thereby avoiding the waste of reagent cards caused by the original puncture mode being unable to flexibly select the number of puncture reagent cards.

[0050] Specifically, the tray 110 is a turntable, which can drive the reagent card to rotate between the first puncture component 120 and the second puncture component 140 according to the number of reagent cards required by the experiment and select one of the components for puncture. For example, when the first number is 4 and the second number is 1, when the experiment is carried out, when the number of surfaces of the reagent card that needs to be punctured (i.e., the number of gel columns of the gel card) is 4 or an integer multiple of 4, such as 4, 8, 12, etc., the reagent card is rotated to the first puncture component 120, and 4 first puncture needles 121 are used for batch puncture to improve the puncture efficiency; when the experiment is carried out with a small demand, that is, the number of surfaces of the reagent card that needs to be punctured is less than 4, that is, the number is 1, 2 or 3, the reagent card is rotated to the second puncture component 140, and 1 second puncture needle 141 is used to perform a precise number of punctures to improve the utilization rate of the reagent card. For example, when the first number is 8, the second number can be any integer from 1 to 8, and when the first number is 10, the second number can be any integer from 1 to 9, that is, the size of the second number must be smaller than the size of the first number, so the options for the first number and the second number are not listed here one by one.

[0051] Obviously, in this embodiment, when the number of surfaces of the reagent card that need to be pierced is greater than the first number and the remainder of the number of surfaces of the reagent card that need to be pierced divided by the first number is an integer multiple of the second number, the first puncture needle 121 and the second puncture needle 141 can be selected for use in combination. For example, when the first number is 4 and the second number is 2, and the number of surfaces that need to be pierced is 10, you can first choose to use 4 first puncture needles 121 for two punctures, and then choose to use 2 second puncture needles 141 for one puncture to meet the needs.

[0052] In the actual experimental process, it is usually the case that the number of surfaces of the reagent card that need to be pierced is greater than the first number and the remainder of the number of surfaces of the reagent card that need to be pierced divided by the first number is not an integer multiple of the first number. For example, when the first number is 8 and the second number is 3, the number of surfaces that need to be pierced is 37. In this case, the waste of the card gel column of the reagent card cannot be avoided. In this case, you can choose to use 8 first puncture needles 121 for 5 punctures to reduce the number of punctures, but it will cause the waste of 3 card gel columns; or use 8 first puncture needles 121 for 4 punctures and 3 second puncture needles 141 for 2 punctures. Compared with the aforementioned method, this method has one more puncture time, but does not cause the waste of card gel columns.

[0053] In other embodiments, the first number and the second number are not limited, and only the number required to achieve batch puncture by the first puncture needle set 121 and accurate number puncture by the second puncture needle set 141 is sufficient. The utility model can puncture the surface of any number of reagent cards according to experimental requirements, thereby improving the puncture efficiency of the reagent cards and avoiding waste of the reagent cards.

[0054] It is worth mentioning that in order to avoid interference between the first puncture assembly 120 and the second puncture assembly 140 , the first drive assembly 130 and the second drive assembly 150 operate independently, that is, the movement state of the first puncture assembly 120 does not affect the movement state of the second puncture assembly 140 .

[0055] In one embodiment, please refer to Figures 1 to 3 The microcolumn gel card puncture structure further includes a first drive assembly 130 and a second drive assembly 150, the first drive assembly 130 and the second drive assembly 150 are respectively used to drive the first puncture needle 121 and the second puncture needle 141 to puncture the surface;

[0056] The fixing base 160 is connected to the supporting tray 110 , and the first driving assembly 130 and the second driving assembly 150 are respectively located on two opposite sides of the fixing base 160 .

[0057] In this embodiment, the first drive assembly 130 and the second drive assembly 150 share a fixed seat 160, so that the first drive assembly 130 and the second drive assembly 150 can operate independently of each other, and the volume of the device is not significantly increased under the volume of the original puncture device, thereby improving space utilization. Among them, the position relationship between the fixed seat 160 and the tray 110 only needs to meet the position where the first drive assembly 130 and the second drive assembly 150 can respectively drive the first puncture needle 121 and the second puncture needle 141 to complete puncturing the surface of the reagent card.

[0058] It should be noted that, in the present embodiment, the first drive assembly 130 further includes a bracket 131, a bracket guide rail (not shown in the figure) and a bracket slider (not shown in the figure), the bracket guide rail is arranged on the bracket 131 along the Y-axis direction, the bracket slider is slidably connected to the bracket guide rail, the bracket slider is transmission-connected to the first puncture needle assembly 120, the bracket slider moves along the bracket slide rail in the Y-axis direction, thereby driving the first puncture needle assembly 120 to move along the Y-axis direction. Furthermore, the first driving assembly 130 also includes a transmission base plate 132 connected to the first puncture assembly 120, and the transmission base plate 132 is transmission-connected to the bracket slider. The movement of the bracket slider drives the transmission base plate 132 to move, thereby driving the first puncture assembly 120 to move along the Y-axis direction; the first puncture assembly 120 also includes a needle seat 123, the needle seat 123 includes a transmission part 1231 and a connecting part 1232, the connecting part 1232 is connected to the first puncture needle 121, and a gear 1321 is provided on the transmission base plate 132. The transmission part 1231 is provided with a rack 12311 transmission-connected to the gear 1321, and the rack 12311 is arranged along the Z-axis direction. The cooperation of the gear 1321 and the rack 12311 drives the needle seat 123 to move along the Z-axis direction, thereby driving the first puncture needle 121 to move along the Z-axis direction.

[0059] It should be noted that, in this embodiment, the arrangement of the gel card columns along the X-axis direction is defined as one row, and the arrangement of the gel card columns in the reagent card is usually arranged in multiple rows with the first number as one row, the connecting portion 1232 extends along the X-axis direction, and the first number of first puncture needles 121 are evenly distributed on the connecting portion 1232 along the X-axis. Therefore, the first puncture needles 121 with the first number complete a surface puncture of the reagent card along the Z-axis, and the puncture of one row of gel card columns can be completed. Therefore, the first puncture needles 121 do not need to move along the extension direction of the row, that is, the X-axis direction. Therefore, the first puncture needles 121 with the first number only need to move in the Y-axis and Z-axis directions to achieve the purpose of batch puncture. In this embodiment, the first drive group 130 does not drive the first puncture assembly 120 to move along the X-axis. In other embodiments, the way in which the first drive assembly 130 drives the first puncture needle assembly 120 to move is not limited.

[0060] In one embodiment, please refer to Figure 1 and Figure 2 The fixed seat 160 includes a fixed plate 161 arranged along the Y-axis direction, the second driving assembly 150 includes a base plate 151, a first transmission belt 152 and a first transmission wheel 153, the base plate 151 is connected to the second puncture needle 141, the first transmission wheel 153 is connected to the fixed plate 161 and is used to realize the rotation of the first transmission belt 152 along the Y-axis direction, the first transmission belt 152 is connected to the base plate 151, thereby driving the second puncture needle 141 to move along the Y-axis direction.

[0061] Specifically, the second drive assembly 150 also includes a first motor for driving the first transmission wheel 153, the first motor is located at one end of the fixed plate 161, and a shielding portion is provided at one end of the fixed plate 161 away from the first motor, and the shielding portion is used to shield the first transmission belt 152 located on the side of the fixed plate 161 to improve the aesthetics of the utility model. Further, the cross section of the fixed plate 161 along the Y-axis direction is in the shape of a "T". It should be noted that the first puncture assembly 120 can also adopt the transmission method in this embodiment, that is, use a motor to drive the transmission wheel to drive the transmission belt to rotate, thereby realizing the movement of the first puncture needle 121 along the Y-axis direction. In other embodiments, the first drive assembly 130 and / or the second drive assembly 150 can adopt other driving methods, such as chain transmission, etc., which are not limited here.

[0062] In one embodiment, please refer to Figure 4 The second driving assembly 150 also includes a connecting member 154, a second transmission wheel 155 and a second transmission belt 156. The connecting member 154 is connected to the second puncture needle 141. The second transmission wheel 155 is connected to the base plate 151 and is used to realize the movement of the second transmission belt 156 along the X-axis direction. The second transmission belt 156 is connected to the connecting member 154, thereby driving the second puncture needle 141 to move along the X-axis direction.

[0063] In this embodiment, the second puncture needle 141 moves along the X-axis in the same manner as that along the Y-axis, and uses the same transmission member and transmission structure, thereby reducing the maintenance cost of the utility model.

[0064] It should be noted that when the number of holes arranged along the X-axis direction of the reagent card is less than or equal to the number of the first puncture needles 121, that is, the first puncture needle 121 assembly can puncture all the holes arranged along the X-axis direction of the reagent card at one time, at this time, the first puncture assembly 120 does not need to move in the X-axis direction.

[0065] In one embodiment, please refer to Figure 4 The second driving assembly 150 also includes a linear motor 157, which is arranged along the Z-axis direction and connected to the connecting member 154. The output end of the linear motor 157 is connected to the second puncture needle 141 and drives the second puncture needle 141 to move along the Z-axis direction to puncture the surface of the reagent card.

[0066] In this embodiment, the linear motor 157 is directly connected to the second puncture needle 141, thereby simplifying the transmission structure, reducing the failure rate and maintenance cost, and improving space utilization due to the reduction of transmission components.

[0067] In this embodiment, the first puncture assembly 120 further includes a rack connected to the first puncture needle 121, and a gear connected to the gear transmission, the rack is arranged along the Z-axis direction, and the first puncture needle 121 is moved along the Z-axis direction by the cooperation of the gear and the rack. In other embodiments, the first puncture needle 121 can be directly connected to the linear motor 157 to achieve movement along the Z-axis direction, and the second puncture needle 141 can be moved along the Z-axis direction by the cooperation of the gear and the rack. The movement of the first puncture needle 121 and the second puncture needle 141 along the Z-axis direction is not limited here.

[0068] In one embodiment, please refer to Figure 4 The second driving assembly 150 also includes a slide rail 158 and a slider 159. The slide rail 158 is arranged on the bottom plate 151 along the X-axis direction. The slider 159 is slidably connected to the slide rail 158. The side of the slider 159 away from the slide rail 158 is connected to the second puncture needle 141. The slider 159 is used to guide the second puncture needle 141 to move along the X-axis direction.

[0069] In this embodiment, a slider 159 is additionally provided to be connected to the second puncture needle 141 , and the slider 159 moves along the slide rail 158 along the X-axis direction, thereby improving the stability of the second puncture needle 141 moving along the X-axis direction.

[0070] In one embodiment, please refer to Figure 4 The second puncture assembly 140 also includes a limiting plate 142, which is connected to the connecting member 154. The limiting plate 142 is used to prevent the second puncture needle 141 from taking the reagent card away from the supporting tray 110 when moving away from the reagent card along the Z axis.

[0071] Specifically, after the second puncture needle 141 pierces the aluminum foil on the surface of the reagent card, there is friction between the aluminum foil and the second puncture needle 141. When the friction is greater than the weight of the reagent card, the second puncture needle 141 moves away from the reagent card along the Z axis, which will drive the reagent card to move in this direction. Therefore, the limiting plate 142 arranged near the surface of the reagent card abuts against the reagent card. When the reagent card is driven by the second puncture needle 141, the limiting plate 142 provides the reagent card with a force opposite to the direction of movement. The force is used to offset the friction, thereby avoiding the problem that the reagent card is taken away from the tray 110 by the second puncture needle 141 and falls due to gravity, and the reagent in the reagent card is spilled and contaminated. Similarly, the same limiting member can also be set at the first puncture needle 121 to achieve the same effect.

[0072] In one embodiment, please refer to Figure 4 The limiting plate 142 includes a limiting portion 1421, which is used to abut against the reagent card. The limiting portion 1421 has a through hole 1421a for the second puncture needle 141 to pass through.

[0073] In one embodiment, please refer to Figure 4 The limiting plate 142 also includes a flange 1422 connected to the limiting portion 1421 , and the flange 1422 is connected to the connecting member 154 .

[0074] In this embodiment, the flange 1422 is used to increase the connection area with the connecting member 154 to ensure that the limiting plate 142 will not fall off the connecting member 154. Specifically, the flange 1422 is provided by extending the outer edge of the limiting portion 1421 in the direction close to the connecting member 154, and the flange 1422 is provided with a mounting hole for the fixing member to pass through. The fixing member passes through the flange 1422 and the connecting member 154, so that the flange 1422 is connected to the connecting member 154.

[0075] The present invention further provides a blood type analyzer 100, which includes an incubation module 170 and a micro-column gel card puncture structure. The specific structure of the micro-column gel card puncture structure refers to the above embodiment. Since the blood type analyzer 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0076] Specifically, the tray 110 is connected to the incubation module 170, and the incubation module 170 has at least two independent cavities, namely, an incubation cavity for incubating the gel card and a sample loading cavity for puncturing and loading. Therefore, the blood type analyzer integrates the puncture, loading and incubation of the gel card into one device, realizing the full automatic and parallel puncture, loading and incubation of the gel card, with high working efficiency and automation, and small space occupied, which is conducive to the development requirements of precise and small gel card experimental equipment.
