Description

Technical Field

[0001] The present invention belongs to the field of medical detection, and more specifically, relates to a multiple detection kit. Background Art

[0002] At present, in the test kits currently available on the market, if too much liquid is dripped into the test kit, the liquid will spread to the end of the absorbent paper, affecting the test results, and even causing the test to be impossible in severe cases. Therefore, a structural design that can prevent this from happening is urgently needed.

[0003] The patent with the patent publication number CN214668603U discloses a multi-drug detection kit, which includes a first detection body and a second detection body, both of which have a display part, a dripping part and a detection card, and the detection kit also includes a socket; the side of the first detection body has a latch; the side of the second detection body has a groove for matching the latch; wherein the ends of the first detection body and the second detection body are both provided with plugs; and the socket has a jack for matching the plug. Through the above-mentioned multi-detection kit, the patent can correspondingly reduce the waste of the multi-detection kit after unpacking, and a switch card is provided on the other dripping part, and the dripping part can be sealed by the switch, that is, after the outer packaging bag is unpacked, the use time after unpacking is extended. However, the patent does not consider the situation that the dripping liquid spreads to the absorbent paper end of the test strip.

[0004] The patent with the patent publication number CN219695137U discloses a rapid multiplex test kit, which includes an upper box body, a lower box body, and a plurality of test strips installed on the lower box body. The upper box body and the lower box body are snap-fitted to each other. A sample addition port and a plurality of observation ports are provided on the surface of the upper box body, and the observation ports are aligned with the display area on the corresponding test strips. A connecting piece is provided inside the upper box body and below the sample addition port, and the connecting piece is connected to the detection area of ​​the plurality of test strips. Through the above-mentioned test kit, the patent only needs to add liquid to one sample addition port, and then evenly divert it to the detection area on each test strip through the connecting piece, avoiding the need to repeatedly add the liquid to be tested to each test strip, thereby improving work efficiency. However, the patent also does not consider the problem that when too much liquid is dripped in, the liquid spreads to the absorbent paper end of the test strip and affects the detection.

[0005] It can be seen from this that there is an urgent need to design a test kit that can prevent the liquid from spreading to the absorbent paper end of the test strip when too much liquid is dropped. Summary of the invention

DETAILED DESCRIPTION

[0046] In order to more clearly understand the above-mentioned purposes, features and advantages of the present disclosure, 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.

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may 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, rather than all of the embodiments.

[0048] Figure 1 FIG. 2 is a schematic diagram showing the overall structure of a multiple detection kit provided by an embodiment of the present invention. Figure 1 As shown, a multiple detection kit comprises an upper shell 1, a lower shell 4 detachably connected to the upper shell 1, and a test strip 14 placed therebetween. The kit can distribute the available test liquid to the test strip 14 as much as possible when the amount of available test liquid is too little, so that the test work can be completed; and can also prevent the liquid from overflowing the test strip 14 and affecting the test work when the amount of liquid is large.

[0049] The upper shell 1 is provided with a sample adding port 2 and an observation window 3 in sequence. The sample adding port 2 is a funnel-shaped structure with a large top and a small bottom. This structure can store the dripping test liquid, so that the test liquid can drip through the bottom opening of the sample adding port 2, and will not cause the liquid to spread on the surface of the upper shell 1 due to excessive liquid dripped into the sample adding port 2 by the user. In this embodiment, Figure 1 As shown, the sample addition port 2 is preferably a circular funnel.

[0050] The test strip 14 is divided into a sample pad 15 , a detection area 16 and absorbent paper 17 in sequence according to the direction of liquid flow.

[0051] A liquid storage device 5 is provided on the inner surface of the lower shell 4 . In the present embodiment, the liquid storage device 5 is square and in the form of a liquid storage tank. The liquid storage device 5 is located at the front of the lower shell 4 .

[0052] A support element 18 for supporting or carrying the test strip 14 is also provided on the inner surface of the lower housing 4. In this embodiment, the support element 18 includes a first support rib 6, a second support rib 11, and a third support rib 12, which are sequentially arranged along the liquid flow direction. The number of the support elements 18 is equal to the number of the observation windows 3, and they are located below the observation windows 3. In this embodiment, the number of the support elements 18 and the number of the observation windows 3 are both two groups, and the starting ends of the two first support ribs 6 are located inside the liquid storage device 5, and the ends thereof extend outside, as shown in FIG. Figure 1 As shown, the starting end of the first support rib 6 is a slope 7. In this embodiment, preferably, the starting end of the slope 7 is connected to the bottom end of the liquid storage device 5. The sample pad 15 of the test strip 14 is carried on the first support rib 6 and the starting end of the sample pad 15 corresponds to the starting end of the slope 7. Since the slope 7 at the front end of the first support rib 6 lowers the height position of the sample pad 15 of the test strip 14, when the liquid drips into the liquid storage device 5, the liquid is more likely to contact the sample pad 15, so that the test strip 14 can 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 at 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 carry the corresponding test strip 14.

[0053] When the upper shell 1 and the lower shell 4 are assembled, the sample adding port 2 is located above the liquid storage device 5. Viewed from the length direction of the lower shell 4, the bottom end of the sample adding port 2 can firmly abut against the two test strips 14 supported on the two first supporting ribs 6. The observation window 3 corresponds to the detection area 16 of the test strip 14 to observe the detection result of the test strip 14.

[0054] Further, in Figure 1In the illustrated embodiment, a first blocking mechanism 8 is disposed in front of the third supporting rib 12 to prevent the liquid in the lower housing 4 from directly flowing to the absorbent paper 17 of the test strip 14. The present invention does not limit the specific position of the first blocking mechanism 8, and it can be disposed at the beginning of the absorbent paper 17 or the detection area 16, or in other words, it can prevent the liquid in the lower housing 4 from reaching the absorbent paper 17 before the liquid on the test strip 14. More specifically, when too much liquid overflows the liquid storage device 5, the liquid will flow in the lower shell 4 toward the end of the lower shell 4 (the end of the absorbent paper 17 of the test strip 14). The flow speed of the liquid in the lower shell 4 is faster than the flow speed on the test strip 14. If no blocking mechanism is provided in the direction of liquid flow, the liquid in the lower shell will flow to the vicinity of the end of the absorbent paper 17 before the test strip 14, and the liquid in the lower shell 4 will be sucked away by the absorbent paper 17. The absorbent paper 17 will weaken the siphon effect due to excessive water absorption, affecting the liquid crawling on the test strip 14, and even making it impossible to crawl on the test strip 14, thereby causing inaccurate test results, and even making it impossible to display the test results. In this embodiment, a first blocking mechanism 8 is provided on the inner surface of the lower shell 4, which can intercept the flowing liquid in the lower shell 4 to prevent the liquid from continuing to flow backward. If the amount of liquid is too large, it can also be diverted to both sides to prevent the liquid in the lower shell 4 from approaching the absorbent paper 17 and causing the siphon effect of the absorbent paper 17 to weaken.

[0055] In this embodiment, the first blocking mechanism 8 is serpentine, and a "ㄩ" shape is formed in the middle of the first blocking mechanism 8. In addition to the functions of blocking and separating liquid, the "ㄩ"-shaped recess in the middle of the first blocking mechanism 8 can also store a portion of liquid, and the protruding portion of the first blocking mechanism 8 can also serve as a supporting 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 liquid is too much, the "ㄩ" shape cannot block it, and the liquid will spread to both sides, and the first blocking mechanism 8 on both sides, which is perpendicular to the test strip 14, will drain the overflowing liquid to both sides of the lower shell 4 to prevent the liquid from flowing to the absorbent paper 17. It can not only block liquid, but also play a hydrophobic role in the case of excessive liquid.

[0056] In other embodiments, the first blocking mechanism 8 may also be configured to be in other shapes, such as a triangle, a wave, or a straight line.

[0057] In the above embodiment of the present invention, the straight lengths of the two ends of the first blocking mechanism 8 are greater than the distance between the outer sides of the two test strips 14. Of course, in other optional embodiments, the first blocking mechanism 8 also needs to meet the above conditions.

[0058] In the above-mentioned embodiments of the present invention, Figure 1As shown, both ends of the first blocking mechanism 8 are spaced from the side wall of the lower housing 4, that is, both ends of the first blocking mechanism 8 are a certain distance away from the side wall of the lower housing 4, which can prevent the liquid from climbing out of the lower housing 4 along the ribs by relying on surface tension and wetting the user's fingers. Of course, in other optional embodiments, both ends of the first blocking mechanism 8 can also extend to connect to the side wall of the lower housing 4, which can better prevent the liquid from continuing to flow to the rear or the end of the test strip 14.

[0059] In the above-mentioned embodiments of the present invention, Figure 1 As shown, the angle range of the slope 7 can be 3°-15°, preferably 3° or 15°. As mentioned above, the starting end of the slope 7 is connected to the bottom end of the liquid storage device 5, and 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 slope 7. Therefore, the slope 7 at the front end of the first support rib 6 lowers the height position of the sample pad 15 of the test strip 14, so that the sample pad 15 contacts the inner surface of the lower shell 4. When the liquid is too little (only a shallow layer can be spread), the height of the sample pad 15 is lower at this time, so that it can contact the liquid as much as possible, so that it can quickly absorb the sample liquid, which is convenient for subsequent testing of the test strip 14.

[0060] In the above-mentioned embodiments of the present invention, Figure 1 As shown, a second blocking mechanism 9 is provided in the liquid storage device 5. The second blocking mechanism 9 is preferably in the form of a liquid blocking rib, which is located between the two first support ribs 6. 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 second blocking mechanism 9, the slope 7 and the front end of the liquid storage device 5 form a sampling area, which can block the liquid from spreading in the direction of liquid flow when the liquid is less, and distribute the limited liquid to the test strip 14 as much as possible for sampling and measurement. 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 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, and thus the liquid can be absorbed to the maximum extent to complete the detection when the amount of liquid is less. Of course, in the sampling area enclosed by the second blocking mechanism 9, the slope 7 and the front end of the liquid storage device 5, when the liquid enters the sampling area, it will diffuse evenly around the point of entry, thereby ensuring uniform liquid separation and an equal amount of liquid for each test strip 14.

[0061] In the above-mentioned embodiments of the present invention, Figure 1As shown, a third blocking mechanism 13 is disposed behind the second blocking mechanism 9, and the third blocking mechanism 13 is preferably also in the form of a liquid blocking rib, and its position is located at the same horizontal line as the end of the liquid storage device 5, and the top surface of the third blocking mechanism 13 is flush with the top surface of the liquid storage device 5. The third blocking mechanism 13 can serve as a further blocking structure, and can also play a role in fixing the test strip 14 in cooperation with the side wall of the liquid storage device 5.

[0062] Furthermore, if Figure 1 As shown, the liquid storage device 5 is provided with completely open openings 10 at both ends along the length direction of the lower housing 4. When the amount of liquid dripped in is too much, the liquid will overflow the sample pad 15 of the test strip 14 and the second blocking mechanism 9 and flow around, and a part of it will flow to the third blocking mechanism 13. At this time, the height of the third blocking mechanism 13 is higher than that of the second blocking mechanism 9, which will prevent the liquid from flowing through the middle of the two test strips 14 and causing excessive flooding of the test strips 14, or even directly flowing to the detection area 16 of the test strips 14. Excessive liquid will flow to the openings 10, flow out of the openings 10 and flow through the two sides of the lower housing 4. Therefore, the third blocking mechanism 13 can prevent excessive liquid from excessively flooding the test strip 14, and prevent excessive liquid from directly flowing to the detection area 16 of the test strip 14, causing inaccurate test structure.

[0063] In the above Figure 1 In the embodiment shown, the first blocking mechanism 8 provided at the absorbent paper 17 can prevent the liquid from spreading on the inner surface of the lower housing 4, causing the liquid in the lower housing 4 to reach the absorbent paper 17 before the liquid on the test strip 14, which will cause the absorbent paper 17 to absorb too much liquid in the lower housing 4, or even absorb the liquid in the lower housing 4, causing the liquid on the test strip 14 to fail to climb, affecting the detection. When the sample liquid is dripped in excessive amounts, the excessive liquid overflows the sample pad 15 and the second blocking mechanism 9 of the test strip 14 and flows around, and part of it flows to the third blocking mechanism 13, which blocks the flowing liquid, so that the excessive liquid is discharged from the openings 10 at the two sides of the liquid storage device 5. When the discharge capacity of the opening 10 is less than the amount of sample liquid, 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 first blocking mechanism 8 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 climbing.

[0064] Figure 2 Shows Figure 1A schematic structural diagram of the relative positions of the upper shell and the test strips after the multi-link detection kit is installed. In the present embodiment, the sample adding port 2 is a circular funnel-shaped structure, and the sample adding port 2 is orthographically projected, and its smallest orthographic projection is located between the orthographic projections of the two test strips 14, that is, the narrowest diameter D of the sample adding port is not greater than the inner side edge spacing d of the two test strips, where d is preferably 3-5mm. In the present embodiment, the narrowest diameter D of the sample adding port 2 is at least 3mm, which can ensure smooth dripping of the liquid. In addition, in alternative embodiments, the sample adding port 2 can be other shapes, but it should be ensured that the maximum distance at the smallest point of the sample adding port 2 is also not greater than the inner side edge spacing d of the two test strips.

[0065] Figure 3 Shows Figure 1 A cross-sectional view of a partial structure of a multiplex test kit. Figure 3 As shown, Figure 1 In the embodiment, the outermost distance between the first support ribs 6 in the length direction of the test strip 14 (the first support rib width W2) is less than the test strip width W1, and the height of each first support rib 6 is consistent.

[0066] Figure 4 and 5 They are shown respectively Figure 1 Cross-sectional view of the slope structure with angles of 3° and 15° used in the multiplex detection kit. Figure 4 and 5 As shown, the inclination angle of the slope 7 can be 3° or 15°.

[0067] Figure 6 Shows Figure 1 Schematic diagram of the flow of liquid in the lower shell of the multiple detection kit when the liquid is low. Figure 6 As shown, in Figure 1 In the illustrated embodiment, the second blocking mechanism 9, the slope 7 and the front end of the liquid storage device 5 form a sampling area, and the sample adding port 2 is arranged in the middle of the sampling area so that the distance of the falling liquid to the two test strips 14 is the same, so that the two test strips 14 can be in contact with approximately the same amount of liquid at the same time, so that the amount of liquid involved in the test on the two test strips 14 is approximately equal, ensuring uniform liquid distribution on the two test strips 14. When the liquid dripped into the sampling area is too little, the second blocking mechanism 9 blocks the liquid from spreading in the direction of liquid flow to maximize the use of the limited liquid, and the sample pad 15 of the test strip 14 can absorb the liquid to the maximum extent for inspection and measurement.

[0068] Figure 7 Shows Figure 1 Schematic diagram of the flow of liquid in the lower shell of the multiple detection kit when there is too much liquid. Figure 7 As shown, in Figure 1In the illustrated embodiment structure, 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 second blocking mechanism 9 to flow around, and a part of it will flow to the third blocking mechanism 13. At this time, the height of the third blocking mechanism 13 is higher than the height of the second blocking mechanism 9, which will prevent the overflowing liquid from flowing through the middle of the two test strips 14 and causing excessive submergence of the test strips 14, or even directly flowing to the detection area 16 of the test strip 14. 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, thereby preventing excessive liquid from flowing directly to the detection area 16 of the test strip 14 and causing inaccurate test structure.

[0069] Figure 8 Shows Figure 1 Schematic diagram of the flow of liquid in the lower shell of the multiple detection kit when there is too much liquid. Figure 8 As shown, in Figure 1 In the illustrated embodiment structure, when there is too much liquid in the sampling area (more liquid), the excess liquid overflows the second blocking mechanism 9 and flows to the third blocking mechanism 13. The third blocking mechanism 13 blocks the overflowing liquid, and the blocked liquid will be discharged from the openings 10 at both side 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 shell 4 to the end of the test strip 14 (at the absorbent paper 17). At this time, the first blocking mechanism 8 located at the end can prevent the liquid from flowing to the end, thereby preventing the liquid from being absorbed by the absorbent paper 17.

[0070] Figure 9-11 Shows Figure 1 Three alternative embodiments of the middle opening structure and corresponding schematic diagrams of the liquid flowing in the lower shell when there is too much liquid. Figure 1 Compared with the embodiment structure, in the alternative embodiment, as Fig. 9 As shown, both sides of the opening 10 at both side ends of the liquid storage device 5 can be connected to the side walls of the lower shell 4. This structure expands the space of the liquid storage device 5, allowing the liquid storage device 5 to store more liquid. Figure 1 Compared with the embodiment structure, in the alternative embodiment, as Fig.10 As shown, the side of the opening 10 away from the starting end of the sample pad 15 can be connected to the side wall of the lower housing 4, such as Fig.10 As shown in the right side, the excess liquid can flow out of this opening 10 and continue to flow toward the front of the lower housing 4. Figure 1 Compared with the embodiment structure, in the alternative embodiment, as Fig.11As shown, the two sides of the opening 10 can be appropriately expanded 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 to be stored in the closed space, which also expands the space of the liquid storage device 5, so that the liquid storage device 5 can 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 shell of the test kit when there is too much liquid.

[0071] Fig.12 Shows Figure 1 Schematic diagram of the structure in which both ends of the liquid storage device are completely closed. Figure 1 Compared with the embodiment structure, in the alternative embodiment, as Fig.12 As shown, both sides of the liquid storage device 5 can be closed without opening 10. This structure is suitable for the case where the liquid in the sampling area is relatively low. When the liquid in the sampling area is relatively low, the liquid will be directly blocked by the second blocking mechanism 9 to spread in the flow direction and the liquid will be distributed to the test strip 14 for sampling and measurement.

[0072] Fig.13 Shows Figure 1 Another structural design of the first blocking mechanism 8 at the absorbent paper end of the test strip in the multiple detection kit and a schematic diagram of the liquid spreading and flowing to the first blocking mechanism and being blocked when there is too much liquid. Fig.13 As shown, the two sides of the first blocking mechanism 8 in this embodiment are connected to the two side walls of the lower housing 4. When excessive liquid flows to the first blocking mechanism 8, the first blocking mechanism 8 will block 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, preventing the end from absorbing too much liquid first and affecting the test. In this embodiment, the first blocking mechanism 8 can also adopt a serpentine liquid blocking rib. Of course, in an alternative embodiment, the first blocking mechanism 8 can also be set to a liquid blocking rib of other shapes, such as a triangular, wavy or straight liquid blocking rib.

[0073] Fig.14 Shows Figure 1 Schematic diagram of another structural design of the test strip and the third supporting rib in the multiple detection kit. Fig.14 As shown, Figure 1 The structure of the lower shell shown is similar, except that the two test strips 14 may be different (eg, different lengths), 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 may be changed.

[0074] In summary, the present invention can prevent the liquid in the lower housing 4 from spreading to the end of the test strip 14 before the liquid on the test strip 14 when the amount of liquid dripped in is too much, and prevent the absorbent paper 17 at the end of the test strip 14 from being filled up first, thereby affecting the siphoning effect of the liquid on the test strip 14 and affecting the accuracy of the test. The present invention can also ensure that the test result of the test strip will not be affected when the amount of liquid dripped (liquid) is too little, and can also ensure that the test result of the test strip will not be affected when the amount of liquid dripped (liquid) is too much.

[0075] The above is merely an embodiment of the present disclosure, which enables 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 may 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.
