Description

Technical Field

[0001] The utility model relates to the technical field of in vitro diagnosis, in particular to a reagent bin and a sample analyzer. Background Art

[0002] The sample analyzer includes a reagent chamber for storing reagents. Some reagents can only remain active at low temperatures (eg, 2-8° C.), and in order to prevent these reagents from deteriorating, the reagent chamber is constructed as a low-temperature environment.

[0003] The reagent compartment is not a completely closed structure. For example, a sampling hole is provided on the top of the reagent compartment for a sampling needle to enter. In addition, when the reagent in the reagent compartment is consumed, the reagent compartment needs to be opened to load the reagent. Specifically, the drawer containing the reagent kit can be pulled out of the reagent compartment to replace the reagent kit with insufficient remaining quantity.

[0004] During the above-mentioned sampling and reagent loading process, the hot air outside the reagent compartment (relative to the temperature inside the reagent compartment) will inevitably enter the reagent compartment. When the hot air encounters the outer wall of the reagent kit with a low temperature inside the reagent compartment, condensation water will be generated on the outer wall of the reagent kit. Condensation water will cause the following problems: 1) For the reagent kits that need to be replaced in the drawer, the user is prone to slipping when grabbing the reagent kit; 2) For the reagent kits that do not need to be replaced in the drawer temporarily, condensation water will cover the outer wall of the reagent kit, affecting the heat exchange efficiency. Utility Model Content

[0005] The utility model aims to provide a reagent bin and a sample analyzer, which can remove condensed water on the surface of the reagent box when the drawer is pulled out from the bin body.

[0006] To achieve the above objectives, in a first aspect, a reagent tank is provided, comprising:

[0007] A tank body having an opening and a chamber communicating with the opening;

[0008] A drawer, entering and exiting the chamber from the opening, the drawer being used to place a reagent box, and a side wall of the reagent box being at least partially not covered by the drawer; and

[0009] The flexible contact component is arranged at the opening and is located on a moving track formed by the reagent box driven by the drawer.

[0010] In some embodiments, the flexible contact member is mounted on an inner wall of the chamber body and extends toward the location of the reagent box.

[0011] In some embodiments, the flexible contact member comprises:

[0012] A connecting portion connected to the inner wall of the bin body; and

[0013] The wires are closely arranged at the connecting portion, and the hanging ends of the wires face the reagent kit.

[0014] In some embodiments, the flexible contact member is a brush.

[0015] In some embodiments, the flexible contact member is arranged around the circumference of the opening, and the flexible contact member is located on a moving track of the drawer, so that when the drawer moves, the outer side surface of the drawer contacts the flexible contact member.

[0016] In some embodiments, a drainage channel and a drainage port connected to the drainage channel are provided on the bottom wall of the bin body.

[0017] In some embodiments, a water receiving box is provided on the water outlet of the drain port; and / or a filter is provided on the drain port.

[0018] In some embodiments, a refrigeration component is disposed on the lower end surface of the warehouse body, and a heat preservation layer is disposed on the outer surface of the warehouse body.

[0019] In some embodiments, a guide component is further provided in the bin body, the guide component extends along the direction in which the drawer enters and exits the opening, and the drawer is connected to the guide component; and / or

[0020] The opening includes a first opening and a second opening. The size of the first opening is different from the size of the second opening. The length of the flexible contact part in the first opening is different from the length of the flexible contact part in the second opening.

[0021] In a second aspect, a sample analyzer is provided, including: the above-mentioned reagent chamber.

[0022] Compared with the prior art, the beneficial effect of the utility model is that since a flexible contact component is provided on the opening of the chamber body, and the flexible contact component is on the moving track of the reagent box, when the drawer drives the reagent box to move outward, the outer surface of the reagent box contacts the flexible contact component, and then the flexible contact component scrapes off the condensed water on the outer surface of the reagent box, so that the condensed water leaves the outer surface of the reagent box. It can be seen that the reagent chamber of the present application can clean the condensed water on the surface of the reagent box, which is not only convenient for operators to replace or process the reagent box, but also improves the heat exchange efficiency of the reagent box in the drawer that does not need to be replaced temporarily.

DETAILED DESCRIPTION

[0030] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and through specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the utility model, rather than to limit the utility model. It is also necessary to explain that, for the convenience of description, only the parts related to the utility model are shown in the accompanying drawings, rather than all.

[0031] Some directional words are defined in the present utility model. Unless otherwise specified, the directional words used, such as "up", "down", "left", "right", "inside" and "outside", are used for ease of understanding and therefore do not constitute limitations on the protection scope of the present utility model.

[0032] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0033] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The sample analyzer can be used for biological sample analysis, where the biological sample can be blood, saliva, urine, feces, etc. When the sample analyzer is used, it is necessary to add appropriate reagents to the sample, so that the sample and the reagent react to obtain a test liquid, and the test liquid is subjected to appropriate tests to obtain the test information of the sample, and the test information is analyzed to obtain the analysis result of the sample.

[0035] Some reagents can only remain active at low temperatures (for example, 2 to 8°C). In order to prevent these reagents from deteriorating, the reagent compartment is constructed as a low-temperature environment. In order to facilitate the sampling of reagents, a sampling hole for the sampling needle to be inserted will be opened on the top of the reagent compartment. In addition, as the reagents are continuously used, when the reagents in the reagent compartment are consumed, the reagent compartment needs to be opened to load the reagents. Specifically, the reagent kit can be placed in a drawer, and the reagent kit can be moved in and out of the reagent compartment by pushing and pulling the drawer to replace the reagent kit with insufficient remaining quantity. In the above two processes, the hot air outside the reagent compartment can enter the inside of the reagent compartment. When the hot air encounters the outer wall of the reagent kit with a low temperature, condensation water will be generated on the outer wall of the reagent kit. Condensation water will bring the following problems: 1) For the reagent kit that needs to be replaced in the drawer, the user is prone to slipping when grabbing the reagent kit; 2) For the reagent kit that does not need to be replaced temporarily in the drawer, the condensation water covers the outer wall of the reagent kit, affecting the heat exchange efficiency.

[0036] The embodiment of the utility model provides a reagent bin to remove condensed water on the surface of the reagent kit when the drawer is pulled out of the bin body, so that the user can grasp the surface of the reagent kit steadily when replacing the reagent kit, and since the condensed water on the surface of the reagent kit is removed, the heat exchange efficiency of the reagent kit that does not need to be replaced is no longer affected.

[0037] Figure 1 and Figure 2 The schematic diagrams of the reagent compartment are shown respectively. Figure 1 and Figure 2 The reagent compartment includes a compartment body 1 and a drawer 2 movably arranged in the compartment body 1. A hollow chamber 11 is arranged inside the compartment body 1. An opening 12 communicating with the chamber 11 is arranged on the front side of the compartment body 1. The drawer 2 extends into the chamber 11 through the opening 12 and can move in the chamber 11. In this embodiment, the states of the drawer 2 before and after the movement are defined as a first state and a second state, respectively. The first state is as follows: Figure 1 As shown, the drawer 2 is in the chamber 11 of the bin body 1, and the opening 12 is closed; the second state is as shown in FIG. Figure 2 As shown, the drawer 2 is exposed outside the bin body 1. It can be understood that in other embodiments, the drawer 2 can also have a third state, a fourth state, etc. between the first state and the second state.

[0038] As an example of the movement of the drawer 2, the drawer 2 may be moved in the warehouse body 1 by linear movement. For example, the drawer 2 is connected to the warehouse body 1 by a guide component 4 such as a linear slide rail or a linear slide groove. Specifically, a guide component 4 extending in the same direction as the chamber 11 is provided in the warehouse body 1, and the drawer 2 is connected to the guide component 4, so that the drawer 2 moves linearly in the chamber 11 with the aid of the guide component 4. It should be noted that the guide component 4 may be provided in the chamber 11; it may also be provided in a channel that is located at a different position from the chamber 11 and is independently provided, and the drawer 2 is located in the chamber 11 and is connected to the guide component 4 in the channel.

[0039] like Figure 2 As shown, the drawer 2 has a storage area inside, and the storage area is used to place a reagent kit 3 for storing reagents, such as Figure 2 As shown, a plurality of reagent kits 3 are placed side by side in the storage area. Optionally, the plurality of reagent kits 3 are placed sequentially along the direction of the drawer 2 entering and exiting the chamber 11. Commonly, the storage area is open at the top to facilitate taking out or putting in the reagent kit 3 from the top of the storage area.

[0040] like Figure 2 As shown, when the drawer 2 is in the first state, the entire storage area is located in the chamber 11; when the drawer 2 is in the second state, the entire storage area is located outside the chamber 11, and the reagent kit 3 in the drawer 2 can be replaced at this time.

[0041] It can be understood that a limiting groove (not shown) compatible with the shape of the reagent kit 3 can be set in the storage area, and the reagent kit 3 can be detachably set in the limiting groove. When the reagent kit 3 is placed in the limiting groove, the position of the reagent kit 3 relative to the drawer 2 will not change. During the process of moving the drawer 2, the reagent kit 3 will not be displaced relative to the drawer 2.

[0042] In one example, the reagent box 3 has a cylindrical shape, and the limiting groove has a circular shape that matches the diameter of the cylinder.

[0043] like Figure 2 As shown, the opening 12 of the reagent box 3 faces upward, and it can also be considered that the reagent box 3 is arranged in the drawer 2 in a longitudinal direction, and the reagent box 3 can be taken out or put back in the drawer 2 in the up and down direction. In addition, the side wall of the reagent box 3 is exposed outside the drawer 2, or the side wall of the reagent box 3 is at least partially not covered by the drawer 2. Specifically, the height of the side wall of the drawer 2 (if any) is lower than the height of the top of the reagent box 3.

[0044] like Figure 2 As shown, a sampling hole 13 connected to the chamber 11 is provided on the top of the compartment body 1, and the arrangement of the sampling holes 13 is the same as the arrangement direction of the reagent kit 3 in the storage area, so that when the drawer 2 is in the first state, the position of the reagent kit 3 corresponds to the position of the sampling hole 13, so that the sampling needle passes through the sampling hole 13 and extends into the reagent kit 3.

[0045] Figure 3 shows a schematic diagram of the reagent compartment after removing drawer 2. Figure 3 In this embodiment, the opening 12 of the storage body 1 includes a first opening 121 located on the left and a second opening 122 located on the right. The height of the first opening 121 is lower than the height of the second opening 122 to accommodate reagent kits 3 of different heights. Accordingly, the chamber 11 includes a first chamber 111 connected to the first opening 121 and a second chamber 112 connected to the second opening 122. The drawer 2 passes through the first opening 121 and the second opening 122 to enter the first chamber 111 and the second chamber 112 respectively, and is movably arranged in the first chamber 111 and the second chamber 112.

[0046] like Figure 3As shown, the side walls of the first opening 121 and the second opening 122 are provided with flexible contact parts 5, and the flexible contact parts 5 are located on the moving track of the reagent box 3, that is, when the drawer 2 drives the reagent box 3 to move, the outer surface of the reagent box 3 contacts the flexible contact parts 5, so that the flexible contact parts 5 scrape the condensed water attached to the outer surface of the reagent box 3 from the outer surface of the reagent box 3, and remove the condensed water on the outer surface of the reagent box 3. The length of the flexible contact parts 5 in the second opening 122 is greater than the length of the flexible contact parts 5 in the first opening 121, so that the length of the flexible contact parts 5 is adapted to reagent boxes 3 of different heights.

[0047] like Figure 3 As shown, the flexible contact part 5 is arranged at least on the left and right sides of the opening 12, so that when the drawer 2 is pulled out, the side walls on the left and right sides of the reagent box 3 can contact the flexible contact part 5, ensuring that there is no condensation water on the side walls on the left and right sides of the reagent box 3, which is convenient for the operator to grab the reagent box 3.

[0048] like Figure 3 As shown, further, the length of the flexible contact part 5 starts from the lower end of the side wall of the drawer 2 and extends upward to the top of the reagent box 3, so that when the drawer 2 is pulled out, the side walls of the drawer 2 and the side walls of the reagent box 3 can both contact with the flexible contact part 5, and while removing the condensed water on the outer surface of the reagent box 3, the condensed water on the surface of the drawer 2 can also be removed, so as to improve the heat exchange efficiency of the surface of the drawer 2, and then the heat on the outer surface of the reagent box 3 can be indirectly discharged from the outer surface of the drawer 2, which can also appropriately improve the heat exchange efficiency of the reagent box 3.

[0049] like Figure 3 As shown, further, the flexible contact component 5 can also be arranged on the bottom wall of the opening 12, so that when the drawer 2 is pulled out, the bottom of the drawer 2 can contact the flexible contact component 5, so that the flexible contact component 5 removes condensed water at the bottom of the drawer 2, thereby indirectly improving the heat exchange efficiency of the test kit 3.

[0050] like Figure 3 As shown, the flexible contact member 5 can be considered to extend along the circumference of the opening 12 , so that the condensed water on the circumferential outer surface of the drawer 2 and the side wall of the reagent box 3 can be removed by the flexible contact member 5 .

[0051] As an example of the flexible contact component 5, the flexible contact component 5 can be a brush, which includes a plurality of closely arranged filaments, wherein the fixed ends of the filaments are connected to the inner wall of the opening 12, the suspended ends of the filaments extend toward the outer surface of the reagent box 3 and / or the outer peripheral surface of the drawer 2, and the suspended ends are on the moving trajectory of the reagent box 3 and / or the drawer 2, so that when the reagent box 3 and / or the drawer 2 pass by the suspended ends of the filaments, the suspended ends contact the outer surfaces of the reagent box 3 and / or the drawer 2, thereby scraping off the condensed water.

[0052] The many wires mentioned above can be closely arranged on a connecting part, and the connecting part can be rigid or flexible. As an example, the connecting part can be a side surface of a connecting plate 51 , and the wires are connected to the connecting plate 51 , and the connecting plate 51 is installed on the inner wall of the opening 12 .

[0053] Figure 4 An exploded view of the reagent compartment is shown with drawer 2 removed. Figure 4 The warehouse body 1 includes a bottom plate 101, a left side plate 102, a middle partition plate 103, a right side plate 104, a top plate 105 and a back plate 106. The bottom plate 101 is arranged horizontally, the left side plate 102, the middle partition plate 103 and the right side plate 104 are arranged vertically, the left side plate 102 is located at the left end of the upper surface of the bottom plate 101, the right side plate 104 is located at the right side of the upper surface of the bottom plate 101, the middle partition plate 103 is located in the middle of the upper surface of the bottom plate 101, the back plate 106 is located at the rear side of the bottom plate 101 and connected to the left side plate 102, the middle partition plate 103 and the right side plate 104, and the top plate 105 is arranged horizontally and connected to the top of the left side plate 102, the middle partition plate 103, the right side plate 104 and the back plate 106. Therefore, the left side and the right side of the middle partition plate 103 define the first opening 121 and the first chamber 111 and the second opening 122 and the second chamber 112, respectively.

[0054] Since in this embodiment, the lower end of the first opening 121 and the lower end of the second opening 122 are located at the same height, and the height of the upper end of the first opening 121 is lower than the height of the upper end of the second opening 122, so that a step is formed at the connection between the first opening 121 and the second opening 122, the top plate 105 includes a first top plate 1051, a second top plate 1052 and a third top plate 1053, the first top plate 1051 is connected to the left side plate 102 and the middle partition plate 103, the second top plate 1052 is connected to the left side of the middle partition plate 103, and the third top plate 1053 is connected to the middle partition plate 103 and the right side plate 104.

[0055] like Figure 4 As shown, the connecting plate 51 for installing the wire can be installed on the upper surface of the bottom plate 101, the side surface of the left side plate 102, the left and right sides of the middle partition plate 103, and the left side surface of the right side plate 104.

[0056] Figure 5 Schematic diagram of the bottom plate 101 is shown. Figure 5 A drainage channel 14 is provided on the upper surface of the bottom plate 101 (which can also be considered as the bottom wall of the opening 12) so that condensed water can gather on the upper surface of the bottom plate 101. A drainage port 15 is provided on the drainage channel 14. The position of the drainage port 15 is relatively low, so that the condensed water in the drainage channel 14 flows to the drainage port 15 under the action of gravity and is discharged from the drainage port 15.

[0057] Figure 6 Shows Figure 5 A partial enlarged view of the A in the middle. Figure 6 A filter 9, such as a filter net, is provided on the drain outlet 15 to filter impurities in the condensed water.

[0058] like Figure 4 As shown, a water receiving box 8 is provided below the water outlet of the drain port 15 for receiving condensed water discharged from the drain port 15 .

[0059] like Figure 4 As shown, a refrigeration component 6 is provided at the bottom of the warehouse body 1, and the refrigeration component 6 can be any component capable of generating cold in the prior art. The refrigeration component 6 includes a refrigeration surface and a heat dissipation surface, the refrigeration surface faces the warehouse body 1, and the heat dissipation surface is away from the warehouse body 1. An insulation layer 7 is provided on the periphery of the warehouse body 1 to slow down the loss of temperature in the warehouse body 1. A heat dissipation component 61 is provided on one side of the refrigeration component 6, and the heat dissipation component 61 can be a fan.

[0060] like Figure 4 As shown, the insulation layer 7 includes a bottom insulation board 71, a front insulation board 72, a rear insulation board 73, a left insulation board 74, a right insulation board 75, and a top insulation board, and the positions of the above insulation boards are arranged at corresponding positions of the warehouse body 1, wherein the first top board 1051, the second top board 1052 and the third top board 1053 are equivalent to the top insulation board. The material of the insulation layer 7 can be phenolic resin (PF) or polyurethane (PU).

[0061] The working principle of the reagent compartment is as follows:

[0062] The operator loads the reagent kit 3 into the drawer 2, pushes the drawer 2 into the opening 12, and closes the drawer (eg, Figure 1 When the reagent box 3 needs to be replaced, the drawer 2 is opened, and the flexible contact part 5 will brush off the condensed water attached to the reagent box 3 when the drawer 2 is pulled out. Figure 2 The operator can replace the reagent kit 3. After the reagent kit 3 is replaced, the operator can push the drawer 2 to the closed state.

[0063] When the condensed water in the drainage channel 14 accumulates to a certain extent, the condensed water will be discharged into the water receiving box 8 through the drainage port 15 on the bottom plate 101 , and the condensed water will be filtered by the filter 9 installed on the drainage port 15 when passing through the drainage port 15 .

[0064] When the reagent compartment is in use, the drawer 2 can be pulled out of the compartment body 1. At this time, the surfaces of the drawer 2 and the reagent reagent 3 will contact the flexible contact part 5, and then the flexible contact part 5 will scrape off the condensed water, making it convenient for the operator to replace and handle the reagent reagent 3. Moreover, since there is no condensed water on the surface of the reagent reagent 3 that does not need to be replaced temporarily in the drawer, when the drawer 2 is pushed back into the compartment body 1, the heat exchange efficiency of the reagent reagent 3 is improved.

[0065] The above is a description of the embodiments of the utility model. Through the above description of the disclosed embodiments, professionals and technicians in the field can implement or use the utility model. Various modifications to these embodiments will be obvious to professionals and technicians in the field. The general principles defined in this article can be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to these embodiments shown in this article, but will comply with the widest range consistent with the principles and novelties disclosed herein.
