Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of medical detection, and more particularly, relates to a multi-association detection kit. BACKGROUND

[0002] At present, the detection kit circulating on the market adopts the following structure scheme to realize detection:

[0003] (1) a plurality of sample adding openings are used to respectively correspond to relevant test strips for sample adding detection, and the scheme has the disadvantage that each project needs to be separately added, which leads to an increase in the number of sample adding times of the user and is easy to remember the wrong sample adding quantity, thereby reducing the accuracy of the display result;

[0004] (2) a single sample adding opening is used to conduct detection on a plurality of test strips through a liquid distribution cotton, the scheme increases the backflow of the liquid distribution cotton, has the potential risk of uneven liquid distribution, and the liquid distribution cotton itself can absorb part of the sample, if the total amount of the liquid drop is increased, the user can remember the wrong liquid drop or cause the test strip to display the result disorderly; if the total amount of the liquid drop is maintained, the liquid distribution after the flow can cause the test strip to be insufficient in the amount of liquid climbing, and the detection result cannot be read.

[0005] Therefore, the several detection kits on the market all have different disadvantages, and at present, there is an urgent need for a multi-association detection kit which can realize single-hole liquid drop sample adding to meet the detection operation of one and / or a plurality of test strips, and can not affect the test result of one and / or a plurality of test strips in the case of less or more liquid drop amount.

DETAILED DESCRIPTION

[0042] In order to enable the above-mentioned purposes, features and advantages of the present disclosure to be more clearly understood, the embodiments of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0043] In the following description, many specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present disclosure, not all the embodiments.

[0044] Figure 1 An embodiment of the present application is shown Figure 1As shown, a multi-unit test kit includes an upper housing 1, a lower housing 4 detachably connected to the upper housing 1, and a test strip 14 placed between the two. The lower housing 4 is used to receive the test strip 14. This kit can distribute the available test liquid as evenly as possible to the test strip 14 when the amount of liquid available is too small, so that the test can be completed; it can also prevent the liquid from overflowing the test strip 14 and affecting the test when the amount of liquid is too large.

[0045] The upper shell 1 is sequentially provided with a sample inlet 2 and an observation window 3. In this design, it is preferred that there is one sample inlet 2 and two observation windows 3 arranged in parallel. The sample inlet 2 has a funnel-shaped structure, wider at the top and narrower at the bottom. This structure can store the dripping test liquid, allowing it to drip through the bottom opening of the inlet 2 without causing the liquid to spread on the surface of the upper shell 1 due to excessive liquid being added by the user. In this embodiment, as... Figure 1 As shown, the sample inlet 2 is preferably a circular funnel.

[0046] The test strip 14 is divided into a sample pad 15, a test area 16, and absorbent paper 17 in the direction of liquid flow.

[0047] A liquid storage device 5 is provided on the inner surface of the lower housing 4. In this embodiment, the liquid storage device 5 is square and takes the form of a liquid storage tank. The liquid storage device 5 is located at the front of the lower housing 4.

[0048] The inner surface of the lower housing 4 is also provided with support elements 18 for supporting or carrying the test strip 14. In this embodiment, the support element 18 includes a first support rib 6, a second support rib 11, and a third support rib 12 arranged sequentially along the liquid flow direction. The number of support elements 18 is equal to the number of observation windows 3, and they are located below the observation windows 3. The starting ends of the two first support ribs 6 are located inside the liquid storage device 5, and their ends extend along the liquid flow direction, such as... Figure 1 As shown, the starting end of each first support rib 6 is a ramp 7. In this embodiment, preferably, the starting end of the ramp 7 is connected to the bottom end of the liquid storage device 5. The sample pad 15 of the test strip 14 is supported on the first support rib 6, and the starting end of the sample pad 15 corresponds to the starting end of the ramp 7. Thus, the ramp 7 at the front end of the first support rib 6 lowers the height of the sample pad 15 of the test strip 14. When the liquid is dripped into the liquid storage device 5, the liquid can more easily contact the sample pad 15, thereby allowing the test strip 14 to quickly absorb the sample liquid. The second support rib 11 is located in the middle of the lower shell 4, and the third support rib 12 is located in the rear of the lower shell 4. The first support rib 6, the second support rib 11, and the third support rib 12 correspond to each other and support the corresponding test strip 14.

[0049] When the upper shell 1 is assembled with the lower shell 4, the sample inlet 2 is above the liquid storage device 5, and the bottom end of the sample inlet 2 can firmly abut the two test strips 14 carried on the two first support ribs 6 from the length direction of the lower shell 4, and the two observation windows 3 correspond to the test areas 16 of the test strips 14 to observe the test results of the test strips 14.

[0050] The first blocking mechanism 8 is arranged in the liquid storage device 5, which is preferably in the form of a liquid blocking rib located between the two first support ribs 6, and the top surface of the liquid blocking rib is flush with the top surface of the test strip 14 carried on the first support rib 6 after assembly. The first blocking mechanism 8 and the first support rib 11 and the front end of the liquid storage device 5 form a liquid distribution area, which can not only block the flow direction of the liquid, but also uniformly distribute the liquid to the test strip 14. Specifically, in the case of insufficient liquid dropped into the liquid distribution area, the liquid blocking mechanism can block the spread of the liquid in the flow direction and distribute the limited liquid to the test strip 14 for sampling and measurement as much as possible; in the case of excessive liquid dropped into the liquid distribution area, the first blocking mechanism 8 can prevent the liquid from directly overflowing the test strip 14 and affecting the test results. The starting end of the sample pad 15 of the test strip 14 corresponds to the starting end of the slope 7 of the first support rib 6, and the starting end of the slope 7 is connected to the bottom end of the liquid storage device 5, so that the starting end of the sample pad 15 of the test strip 14 is substantially located at the inner surface of the lower shell 4, thereby maximizing the absorption of liquid in the case of insufficient liquid and completing the test. Of course, in the liquid distribution area surrounded by the first blocking mechanism 8, the slope 7 and the front end of the liquid storage device 5, when the liquid enters the liquid distribution area, it will uniformly spread around the falling point as the center, so as to ensure uniform distribution of the liquid, and each test strip 14 receives an equal amount of liquid.

[0051] Further, as shown in Figure 1 The angle range of the slope 7 can be 3°-15°, preferably 3° or 15°. As mentioned earlier, the function of the slope 7 is to lower the height position of the sample pad 15 of the test strip 14, so that the sample pad 15 is in contact with the inner surface of the lower shell 4, thereby enabling the sample pad 15 to contact the liquid as much as possible when the liquid is insufficient (only a shallow layer is formed), so that the sample liquid can be quickly absorbed, facilitating the subsequent test of the test strip 14.

[0052] Further, as shown in Figure 1As shown, the liquid storage device 5 is also provided with a second blocking mechanism 9, the first blocking mechanism 8 and the second blocking mechanism 9 are distributed in a stepped manner along the liquid flow direction, specifically, the second blocking mechanism 9 is arranged behind the first blocking mechanism 8, the second blocking mechanism 9 is preferably also in the form of a liquid blocking rib, the position of the second blocking mechanism 9 is on the same horizontal line with the end of the liquid storage device 5, and the top surface of the second blocking mechanism 9 is flush with the top surface of the liquid storage device 5. The second blocking mechanism 9 can serve as a further blocking structure, and also can cooperate with the side wall of the liquid storage device 5 to fix the test strip 14; at the same time, it can prevent the liquid from flooding the test strip 14 when the liquid is too much, causing the test to be unable to be detected or inaccurate.

[0053] Further, as shown, Figure 1 The liquid storage device 5 is provided with an open opening 10 at both sides along the length direction of the lower shell 4, when the liquid drop-in amount is too much, the liquid will overflow the sample pad 15 of the test strip 14 and the first blocking mechanism 8 and flow to all directions, part of it will flow to the second blocking mechanism 9, at this time, the height of the second blocking mechanism 9 is higher than that of the first blocking mechanism 8, which will block the liquid from flowing between the two test strips 14 to cause excessive flooding of the test strip 14, or even directly flow to the test area 16 of the test strip 14, thus the excessive liquid will flow to the opening 10 and flow out from the opening 10 and flow through the two sides of the lower shell 4. Therefore, the second blocking mechanism 9 can prevent the excessive liquid from spreading in the flow direction to excessively flood the test strip 14, and prevent the excessive liquid from directly flowing to the test area 16 of the test strip 14, causing inaccurate test results.

[0054] Further, in Figure 2In the shown embodiment structure, the front of the second support rib 12 is provided with a third blocking mechanism 13 to prevent liquid from flowing directly to the absorbent paper 17 of the test strip 14. The present application does not limit the specific position of the third blocking mechanism 13, which can be provided at the beginning of the absorbent paper 17 or at the test area 16, or in other words, the third blocking mechanism 13 can block the liquid in the lower shell 4 to reach the absorbent paper 17 before the liquid on the test strip 14. More specifically, when excessive liquid overflows the liquid storage device 5, the liquid will flow to the end of the lower shell 4 (the end of the absorbent paper 17 of the test strip 14) in the lower shell 4, and the flow speed of the liquid in the lower shell 4 is faster than that on the test strip 14. If no blocking mechanism is provided in the direction of the liquid flow, the liquid in the lower shell will flow to the vicinity of the end of the absorbent paper 17 before the liquid on the test strip 14, and the liquid in the lower shell 4 will be absorbed by the absorbent paper 17. The absorbent paper 17 will be over-absorbed, which will weaken the siphon effect and affect the liquid wicking on the test strip 14, or even make the liquid wicking on the test strip 14 impossible, thereby causing inaccurate detection results or even no detection results. In the present embodiment, the third blocking mechanism 13 is provided on the inner surface of the lower shell 4, which can intercept the flowing liquid in the lower shell 4 and prevent the liquid from flowing backward. If the amount of liquid is too large, the liquid can also be diverted to both sides to prevent the liquid in the lower shell 4 from approaching the absorbent paper 17 and weakening the siphon effect of the absorbent paper 17.

[0055] In the present embodiment, the third blocking mechanism 13 is provided on the inner surface of the lower shell 4, which can intercept the flowing liquid in the lower shell 4 and prevent the liquid from flowing backward. If the amount of liquid is too large, the liquid can also be diverted to both sides to prevent the liquid in the lower shell 4 from approaching the absorbent paper 17 and weakening the siphon effect of the absorbent paper 17.

[0056] In the present embodiment, the third blocking mechanism 13 is in the shape of a snake, and a "ㄩ" shape is formed in the middle of the third blocking mechanism 13. In addition to the functions of blocking and dividing liquid, the recess in the middle of the third blocking mechanism 13 in the shape of "ㄩ" can also store a portion of the liquid, and the protruding part of the third blocking mechanism 13 can also serve as a support rib to support the test strip 14. Specifically, in the case of excessive liquid, the "ㄩ" shape first blocks the liquid from flowing to the absorbent paper; if the amount of liquid is too large, the "ㄩ" shape cannot block it, and the liquid will spread to both sides. The part of the third blocking mechanism 13 perpendicular to the test strip 14 on both sides will guide the overflowing liquid to both sides of the lower shell 4, preventing the liquid from flowing to the absorbent paper 17. It can not only block the liquid, but also act as a drainage in the case of excessive liquid.

[0057] In other embodiments, the third blocking mechanism 13 can also be provided in other shapes, such as triangular, wavy or straight line shapes, etc.

[0058] When an excessive amount of sample liquid is added, the excess liquid overflows the sample pad 15 and the first blocking mechanism 8 of the test strip 14 and flows to the surroundings. Some of it flows to the second blocking mechanism 9, which blocks the incoming liquid. This causes the excess liquid to drain from the openings 10 at both ends of the liquid storage device 5. When the drainage capacity of the openings 10 is less than the amount of sample liquid added, the liquid will flow along the inner surface of the lower housing 4 to the absorbent paper 17 of the test strip 14. At this time, the third blocking mechanism 13 located at the absorbent paper 17 can prevent the liquid from flowing to the absorbent paper 17 and being absorbed by the absorbent paper 17, thereby ensuring that the liquid on the test strip 14 can achieve normal liquid climbing.

[0059] Figure 1 It shows Figure 2 A schematic diagram showing the relative positions of the upper casing and test strips after the multi-test kit has been installed. (See diagram for reference.) Figure 3 As shown, in this embodiment, the sample dispensing port 2 is a circular funnel-shaped structure. When the sample dispensing port 2 is projected orthographically, its smallest orthographic projection lies between the orthographic projections of the two test strips 14. That is, the narrowest diameter D of the sample dispensing port is not greater than the distance d between the inner edges of the two test strips, where d is preferably 3-5 mm. In this embodiment, the narrowest diameter D of the sample dispensing port 2 is at least 0.3 cm to ensure smooth liquid dripping. Furthermore, in alternative embodiments, the sample dispensing port 2 can be of other shapes, but it should be ensured that the minimum and maximum distance between the sample dispensing ports 2 is not greater than the distance d between the inner edges of the two test strips.

[0060] Figure 1 It shows Figure 3 A partial structural cross-sectional view of a multi-detection kit. (See attached image.) Figure 1 As shown, Figure 4 In the embodiment, the outermost spacing of the first support rib 6 in the length direction of the test strip 14 (width W2 of the first support rib) is less than or equal to the width W1 of the test strip, and the height of each first support rib 6 is consistent.

[0061] Figure 1 and 5 They are shown respectively Figure 4 Cross-sectional views of the 3° and 15° ramp structures used in the multi-detection kit. (See attached image.) Figure 6 and 5 As shown, the angle of inclination of slope 7 can be 3° or 15°.

[0062] Figure 1 It shows Figure 6 A schematic diagram illustrating the flow of liquid within the lower casing of a multi-sample test kit when the liquid level is low. (See diagram for reference.) Figure 1 As shown, in Figure 7In the illustrated embodiment, the sampling area is formed by the first blocking mechanism 8, the ramp 7, and the front end of the liquid storage device 5. The sample inlet 2 is located in the middle of the sampling area so that the falling liquid reaches the two test strips 14 at the same distance, allowing the two test strips 14 to simultaneously contact approximately the same amount of liquid. This ensures that the amount of liquid participating in the test on the two test strips 14 is approximately equal, guaranteeing uniform liquid distribution on the two test strips 14. When the amount of liquid dripped into the sampling area is insufficient, the first blocking mechanism 8 prevents the liquid from spreading in the direction of liquid flow, maximizing the utilization of the limited liquid. The sample pad 15 of the test strip 14 can absorb the liquid to the maximum extent for testing and measurement.

[0063] Figure 1 It shows Figure 7 A schematic diagram illustrating the flow of liquid within the lower casing of a multi-sample test kit when there is a high liquid content. (See diagram for example.) Figure 1 As shown, in Figure 8 In the illustrated embodiment, when there is too much liquid in the sampling area (a little more liquid), the liquid will overflow the sample pad 15 of the test strip 14 and the first blocking mechanism 8 and flow to the surrounding areas. Some of it will flow to the second blocking mechanism 9. At this time, the height of the second blocking mechanism 9 is higher than that of the first blocking mechanism 8, which will prevent the overflowing liquid from flowing between the two test strips 14 and causing excessive submersion of the test strip 14, or even flowing directly to the test area 16 of the test strip 14. Excess liquid will flow to the opening 10, and flow out from the opening 10 and flow through both sides of the lower shell 4, thereby preventing excessive liquid from flowing directly to the test area 16 of the test strip 14 and causing inaccurate test results.

[0064] Figure 1 It shows Figure 8 A schematic diagram illustrating the flow of liquid within the lower housing of a multi-sample test kit when there is an excess of liquid. (See diagram for reference.) Figure 1 As shown, in Figures 9-11 In the illustrated embodiment, when there is too much liquid in the sampling area (more liquid volume), the excess liquid overflows the first blocking mechanism 8 and flows to the second blocking mechanism 9. The second blocking mechanism 9 blocks the overflowing liquid, and the blocked liquid will be discharged from the openings 10 at both ends of the liquid storage device 5. When the discharge capacity of the openings 10 is less than the amount of liquid in the sampling area, the liquid will flow along the inner surface of the lower housing 4 to the end of the test strip 14 (at the absorbent paper 17). At this time, the third blocking mechanism 13 located at the end can prevent the liquid from flowing to the end and prevent the liquid from being absorbed by the absorbent paper 17.

[0065] Figure 1 It shows Figure 1 Three alternative embodiments of the centrally opened structure and corresponding schematic diagrams of liquid flow within the lower casing in cases where there is a higher liquid content. Figure 9 Compared to the structure of the embodiments provided, in the alternative embodiments, such as Figure 1As shown, the openings 10 at both ends of the liquid storage device 5 can be connected to the side walls of the lower housing 4. This structure expands the space of the liquid storage device 5, allowing it to store more liquid. Figure 10 Compared to the structure of the embodiments provided, in the alternative embodiments, such as Figure 10 As shown, the side of the opening 10 furthest from the starting end of the sample pad 15 can be connected to the side wall of the lower housing 4, as... Figure 1 As shown on the right side, excess liquid can flow out from this opening 10 and continue flowing towards the front of the lower casing 4. Figure 11 Compared to the structure of the embodiments provided, in the alternative embodiments, such as Figure 12 As shown, the two sides of the opening 10 can be appropriately extended outward to close the space, which can increase the liquid storage capacity of the liquid storage area. Excess liquid flows out from this opening 10 into the closed space for storage, which also expands the space of the liquid storage device 5, allowing the liquid storage device 5 to store more liquid. Moreover, the opening of this structure will not flow to the edge of the lower shell 4 when there is too much liquid, thereby further preventing the liquid from seeping out along the connection between the lower shell 4 and the upper shell 1 to the outside of the entire reagent kit shell when there is too much liquid.

[0066] Figure 1 It shows Figure 1 A schematic diagram of a fully enclosed liquid storage device at both ends. Figure 12 Compared to the structure of the embodiments provided, in the alternative embodiments, such as Figure 13 As shown, both ends of the liquid storage device 5 can be closed, without openings 10. This structure is suitable for situations where the liquid level in the sampling area is low. When the liquid level in the sampling area is low, the liquid will be directly blocked by the first blocking mechanism 8 from spreading in the flow direction and will be distributed to the test strip 14 for sampling and measurement.

[0067] Figure 1 It shows Figure 13 This diagram illustrates an alternative structural design of the third blocking mechanism at the absorbent paper end of the test strip in a multi-test kit, and how the liquid spreads and flows to the third blocking mechanism in the event of excessive liquid flow, where the flow is blocked. Figure 14 As shown, in this embodiment, the third blocking mechanism 13 is connected to the two side walls of the lower housing 4. When excessive liquid flows to the third blocking mechanism 13, it will prevent the liquid from continuing to flow to the rear of the lower housing 4 and divert the liquid to the two side walls of the lower housing 4, thereby completely blocking the liquid from flowing to the end of the test strip 14 and preventing the end from absorbing too much liquid and affecting the test. In this embodiment, the third blocking mechanism 13 can also be a serpentine liquid-blocking rib. Of course, in alternative embodiments, the third blocking mechanism 13 can also be configured as other shapes of liquid-blocking ribs, such as triangular, wavy, or straight liquid-blocking ribs.

[0068] Figure 1 It showsFigure 14 FIG. 6 is a schematic view of another structural design of the test strip and the third support rib in the multi-association detection test kit of the present application. Figure 1 As shown, the lower shell 4 is similar to the structure shown in FIG. 2, except that the two test strips 14 can be different (e.g., different in length), and based on the difference between the two test strips 14, the shape of the third support rib 12 at the rear of the lower shell 4 can be changed. ​

[0069] In summary, the present application improves the lower shell of the test kit, provides a test kit for multi-association detection without the need for a single sample hole and a test strip with a lapping liquid cotton, and can ensure that the test results of the test strip will not be affected in the case of a small amount of liquid, and can also ensure that the test results of the test strip will not be affected in the case of a large amount of liquid.

[0070] The above-described embodiments are merely illustrative of the present disclosure and enable those skilled in the art to understand and implement the present disclosure. Various modifications to the embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present disclosure. Therefore, the present disclosure will not be limited to the embodiments described herein, but will conform to the widest scope consistent with the principles and features disclosed herein.​
