Description

Technical Field

[0001] The utility model belongs to the technical field of liquid detection, and particularly relates to a liquid detection cup. Background Art

[0002] In the field of medical detection, liquid detection such as the detection of blood, serum, plasma, urine, saliva, etc. is a relatively common detection. For such detections, generally, a detection cup is used to pre-collect the sample liquid first, and then a detection device on the detection cup or a test strip is inserted into the sample liquid to perform the analysis and detection of specified items, and then the detection results are interpreted. The operation is convenient and fast.

[0003] For example, for the detection of drugs in urine, a urine detection cup is usually used, and several test strips are installed in the urine cup. When a urine sample is added to the urine cup, the test strips in the urine cup show the detection results through immunochromatographic reactions. There are usually two types of existing urine cups: a conical cup or a conical cup with a flat insertion plate cavity on one side. Most conical urine cups assemble the test strips on the inner wall of the urine cup. For the urine cup with a conical cup and a flat insertion plate cavity on one side, an independent insertion plate is usually placed in the insertion plate cavity, and the test strips are assembled on the insertion plate. The advantage of the urine cup with a flat insertion plate cavity is that the test strips are all on the same plane, and the reading results can be quickly input into the information system or printed by means of camera vision reading or laser scanning reading, without manual recording, effectively reducing human errors. However, for the existing detection urine cups, the number of test strips assembled on the urine cup is limited. When more test strips are needed for detection, it is difficult to meet the requirements. In addition, most of the existing detection urine cups can only detect one item. When changing the detection item, different test strips need to be replaced and the sample needs to be re-taken. As a result, the detection efficiency is low and the time consumption is long. Summary of the Utility Model

[0004] The utility model aims to overcome the defects of high preparation cost, low detection efficiency, long time consumption, difficulty in assembling more test strips simultaneously, and large error in manual recording of detection results in the existing liquid detection cup, and provides a liquid detection cup to overcome the above defects.

[0005] To achieve the above object of the invention, the utility model is realized through the following technical solutions:

[0006] A liquid detection cup, comprising:

[0007] A cup body assembly, which includes a cup body. A sample cavity for accommodating a sample to be tested is arranged inside the cup body. A cup cover is provided on the top of the sample cavity. The cup body assembly further includes a cup body insertion plate assembly connected to the outer side wall of the cup body and used for detecting the sample. A cup body insertion plate cavity is arranged inside the cup body insertion plate assembly, and the cup body insertion plate cavity is communicated with the sample cavity;

[0008] An extension unit assembly is provided at the end side of the cup body plug-in board assembly and is detachably connected thereto. The extension unit assembly includes an extension slot, and an accommodation cavity is provided inside the extension slot. An extension plug-in board assembly for detecting a sample is inserted into the accommodation cavity.

[0009] The liquid detection cup of the present utility model includes a cup body assembly. The cup body assembly includes a cup body, a sample cavity for accommodating a sample to be detected is provided inside the cup body, and a cup lid is provided to cover the top of the sample cavity. The cup body assembly further includes a cup body plug-in board assembly connected to the outer side wall of the cup body and used for detecting the sample. A cup body plug-in board cavity is provided inside the cup body plug-in board assembly, and the cup body plug-in board cavity communicates with the sample cavity. The liquid detection cup of the present utility model further includes an extension unit assembly provided at the end side of the cup body plug-in board assembly and detachably connected thereto. The extension unit assembly includes an extension slot, an accommodation cavity is provided inside the extension slot, and an extension plug-in board assembly for detecting the sample is inserted into the accommodation cavity.

[0010] By designing the cup body plug-in board cavity to communicate with the sample cavity, the sample to be detected in the sample cavity flows into the cup body plug-in board cavity, so as to contact the test strip provided in the cup body plug-in board assembly for sample detection. The operation is simple, efficient and time-saving. In addition, by designing the extension unit assembly detachably connected to the cup body plug-in board assembly, it helps to realize simultaneous detection of more test strips. At the same time, the cup body plug-in board assembly and the extension plug-in board assembly are located in the same plane, which helps the external device to quickly read the test strip detection result and input the information into the information system, effectively avoiding large errors in manual recording and making the detection result more accurate. In addition, by designing the extension unit assembly, the type of test strip provided on the extension plug-in board assembly can be flexibly adjusted, which helps to perform multiple detection items simultaneously and further improve the detection efficiency.

[0011] Preferably, the cup body plug-in board assembly includes a cup body plug-in board inserted into the cup body plug-in board cavity. A plurality of cup body slots are provided on the cup body plug-in board, and test strips for detecting the sample are provided in the cup body slots. A label for displaying the test strip result is attached to the surface of the test strip.

[0012] Through the above settings, it helps to assemble multiple test strips on the cup body plug-in board at the same time to perform parallel tests on the sample to be detected, which helps to improve the detection accuracy and effectively save time. In addition, attaching a label to the surface of the test strip helps to read the detection result through camera vision or laser scanning and input the read result into the information system or print it, effectively avoiding large errors in manual recording information.

[0013] Preferably, the top end of the cup body plug-in board cavity is open. When the cup body plug-in board is inserted into the cup body plug-in board cavity, a sealing film is attached to the top end of the cup body plug-in board, so as to seal the top end of the cup body plug-in board cavity.

[0014] With the above settings, it is convenient to install or disassemble the cup body insert plate. At the same time, the selection of the sealing film not only effectively guarantees the sealing performance of the overall structure, but also can be flexibly adjusted according to actual needs.

[0015] Preferably, a communication part is provided between the outer side wall of the cup body and the bottom of the cup body insert plate assembly, and both ends of the communication part are respectively communicated with the sample cavity and the cup body insert plate cavity.

[0016] Preferably, air holes are provided at the bottom of the cup body insert plate cavity, and air columns are provided on the air holes.

[0017] As a further preference, the air column is made of a microporous waterproof and breathable material.

[0018] The micropores on the air column are smaller in diameter than water molecules and larger than air molecules, so that air molecules can pass through the micropores while water molecules cannot, thereby playing a role in ventilation and waterproofing.

[0019] By providing the communication part, the sample cavity and the cup body insert plate cavity are communicated. Add the sample to be tested into the sample cavity, and the sample to be tested flows into the sealed cup body insert plate cavity through the communication part. When the liquid level height in the cup body insert plate cavity is lower than the height of the air column, the gas in the cup body insert plate cavity can flow into the air column and be discharged out through the air hole, so that the sample to be tested in the sample cavity can continue to flow into the cup body insert plate cavity, and the internal space pressure of the cup body insert plate cavity gradually increases. When the liquid level height in the cup body insert plate cavity is higher than the height of the air column, the air column and the air hole are blocked (i.e., sealed by the liquid). At this time, since a closed space is formed inside the cup body insert plate cavity and the liquid continuously flows in, the internal space pressure of the cup body insert plate cavity gradually increases. When the internal space pressure of the cup body insert plate cavity is the same as the internal space pressure of the sample cavity (i.e., the air pressure balance state), the sample to be tested stops flowing into the cup body insert plate cavity. By designing the air hole and the air column, the liquid volume of the sample to be tested entering the cup body insert plate cavity is automatically controlled, which can not only ensure the completion of the detection reaction of the sample to be tested, but also effectively prevent the sample to be tested from flowing in too much and exceeding the test strip detection line, resulting in the invalidation of the detection result.

[0020] Preferably, a limiting rib is further provided at the bottom of the cup body insert plate cavity.

[0021] By providing the limiting rib, it helps to fix and support the cup body insert plate, ensures the same position among different cup bodies, reduces the influence of the position difference of the cup body insert plate on the result, makes the result more accurate. At the same time, it keeps a certain distance between the cup body insert plate and the front wall of the cup body insert plate cavity, preventing the liquid capillary action due to the too small distance between the cup body insert plate and the front wall of the cup body insert plate cavity, and making the liquid climb too high along the gap, resulting in the invalidation of the detection result.

[0022] Preferably, a temperature label groove for placing a temperature label is provided on the outer side wall of the cup body.

[0023] By setting up a temperature label slot, the temperature can be displayed intuitively to prevent sample adulteration.

[0024] Preferably, the expansion board assembly includes an expansion board inserted in the accommodating cavity, the expansion board is provided with a plurality of expansion slots, the expansion slots are provided with expansion test strips for detecting samples, and the surface of the expansion test strips is covered with an expansion label for displaying the test strip results.

[0025] The above-mentioned setting helps to assemble multiple extended test strips on the extended plug board, and conduct parallel tests on the samples to be tested at the same time, which helps to improve the detection accuracy and effectively save time. When testing the sample, just pull out the extended plug board with the extended test strip from the accommodating cavity, and then insert it into the sample cavity set inside the cup body. After the extended test strip absorbs an appropriate amount of the sample to be tested, take out the extended plug board, reinsert it into the accommodating cavity and record the test results displayed on the extended test strip to complete the test.

[0026] Preferably, a cup body male slot is provided on one side of the cup body plug-in plate assembly close to the expansion slot, a female slot is provided on one side of the expansion slot and at a position corresponding to the cup body male slot, the female slot is plug-connected with the cup body male slot, and a male slot adapted to the adjacent female slot is provided on the other side of the expansion slot away from the cup body male slot.

[0027] Preferably, the number of the expansion slots is one or more.

[0028] By setting up multiple independent expansion slots that are plugged and connected to each other, more extended test strips can be tested simultaneously. At the same time, the cup body plug-in board assembly and all the extended plug-in board assemblies are located on the same plane, which helps the external device to quickly read all the test strip test results and input them into the information system, effectively avoiding large errors in manual recording and making the test results more accurate. In addition, the expansion slots can be increased or decreased according to actual needs, and they are easy to install and disassemble, and simple to operate. In addition, the type of extended test strip set on the extended plug-in board assembly inserted into the expansion slot can also be flexibly adjusted to achieve the purpose of testing multiple items at the same time, further improving the detection efficiency.

[0029] Therefore, the utility model has the following beneficial effects:

[0030] (1) The utility model is designed to connect the cup body insert plate cavity with the sample cavity, so that the sample to be tested in the sample cavity flows into the cup body insert plate cavity, thereby contacting the test paper strip set in the cup body insert plate assembly to perform sample testing. The operation is simple, efficient and time-saving;

[0031] (2) By designing an extension unit component that is detachably connected to the cup body plug-in board component, the utility model helps to achieve simultaneous detection of more test strips. At the same time, the cup body plug-in board component and the extension plug-in board component are located in the same plane, which helps external devices to quickly read the test results of the test strips and input the information into the information system, effectively avoiding large manual recording errors and making the test results more accurate.

[0032] (3) By designing the extension unit component, the type of test strips set on the extension plug-in board component can be flexibly adjusted, which helps to carry out multiple detection items simultaneously and further improves the detection efficiency. Brief Description of the Drawings

[0044] As Figure 1-8 shown, the liquid detection cup of the present utility model includes a cup body assembly 1. The cup body assembly 1 includes a cup body 2, and a sample cavity 3 for accommodating a sample to be detected is arranged inside the cup body 2. A cup cover 4 is provided on the top of the sample cavity 3. The cup body assembly 1 further includes a cup body plug-in board assembly 5 connected to the outer side wall of the cup body 2 and used for detecting the sample. A cup body plug-in board cavity 6 is arranged inside the cup body plug-in board assembly 5, and the cup body plug-in board cavity 6 is communicated with the sample cavity 3. The liquid detection cup of the present utility model further includes an expansion unit assembly 7 arranged at the end side of the cup body plug-in board assembly 5 and detachably connected thereto. The expansion unit assembly 7 includes an expansion slot 8, and a receiving cavity 9 is arranged inside the expansion slot 8. An expansion plug-in board assembly 10 for detecting the sample is inserted into the receiving cavity 9.

[0045] In the present utility model, by designing the cup body plug-in board cavity 6 to be communicated with the sample cavity 3, the sample to be detected in the sample cavity 3 flows into the cup body plug-in board cavity 6, so as to contact the test strip 13 arranged in the cup body plug-in board assembly 5 for sample detection. The operation is simple, efficient and time-saving. In addition, by designing the expansion unit assembly 7 detachably connected to the cup body plug-in board assembly 5 in the present utility model, it helps to realize the simultaneous detection of more test strips 13. At the same time, the cup body plug-in board assembly 5 and the expansion plug-in board assembly 10 are located in the same plane, which helps the external device to quickly read the detection results of the test strip 13 and input the information into the information system, effectively avoiding large manual recording errors and making the detection results more accurate. In addition, by designing the expansion unit assembly 7 in the present utility model, the type of the test strip 13 arranged on the expansion plug-in board assembly 10 can be flexibly adjusted, which helps to simultaneously perform multiple detection items and further improve the detection efficiency.

[0046] As an implementation manner, the cup body plug-in board assembly 5 includes a cup body plug-in board 11 inserted into the cup body plug-in board cavity 6. A plurality of cup body slots 12 are arranged on the cup body plug-in board 11, and a test strip 13 for detecting the sample is arranged in the cup body slots 12. A label 14 for displaying the test strip result is attached to the surface of the test strip 13.

[0047] The above arrangement helps to simultaneously assemble multiple test strips 13 on the cup body insert plate 11, and to perform parallel tests on the samples to be tested, which helps to improve the detection accuracy and effectively save time. In addition, a label 14 is attached to the surface of the test strip 13, which helps to read the test results through camera vision or laser scanning and input the read results into the information system or print, effectively avoiding large errors in manual recording of information.

[0048] As an embodiment, the top of the cup body insert plate cavity 6 is open. When the cup body insert plate 11 is inserted into the cup body insert plate cavity 6, a sealing film 15 is attached to the top of the cup body insert plate 11, so that the top of the cup body insert plate cavity 6 is sealed.

[0049] The above arrangement facilitates installation or removal of the cup body insert plate 11 , and the sealing film 15 is selected to effectively ensure the sealing of the overall structure and can be flexibly adjusted according to actual needs.

[0050] As an implementation mode, a connecting portion 16 is provided between the outer wall of the cup body 2 and the bottom of the cup body inserting plate assembly 5 , and both ends of the connecting portion 16 are respectively connected to the sample cavity 3 and the cup body inserting plate cavity 6 .

[0051] As an implementation manner, a ventilation hole 17 is provided at the bottom of the cup body inserting plate cavity 6 , and a ventilation column 18 is provided on the ventilation hole 17 .

[0052] As another embodiment, the material of the breathable column 18 is a microporous waterproof breathable material.

[0053] The diameter of the micropores on the breathable column 18 is smaller than the diameter of water molecules and larger than the diameter of air molecules, thereby enabling air molecules to pass through the micropores while water molecules cannot pass through, thereby achieving a breathable and waterproof effect.

[0054] By setting the connecting part 16, the sample chamber 3 is connected to the cup body insertion plate chamber 6. The sample to be tested is added into the sample chamber 3, and the sample to be tested flows into the sealed cup body insertion plate chamber 6 through the connecting part 16. When the liquid level height in the cup body insertion plate chamber 6 is lower than the height of the air permeable column 18, the gas in the cup body insertion plate chamber 6 can flow into the air permeable column 18 and be discharged outwards through the air permeable holes 17, so that the sample to be tested in the sample chamber 3 can continue to flow into the cup body insertion plate chamber 6, and the internal space pressure of the cup body insertion plate chamber 6 gradually increases. When the liquid level height in the cup body insertion plate chamber 6 is higher than the height of the air permeable column 18, the air permeable column 18 and the air permeable holes 17 are blocked (i.e., sealed by the liquid). At this time, since a closed space is formed inside the cup body insertion plate chamber 6 and the liquid continuously flows in, the internal space pressure of the cup body insertion plate chamber 6 gradually increases. When the internal space pressure of the cup body insertion plate chamber 6 is the same as the internal space pressure of the sample chamber 3 (i.e., the air pressure balance state), the sample to be tested stops flowing into the cup body insertion plate chamber 6. By designing the air permeable holes 17 and the air permeable column 18, the amount of liquid of the sample to be tested entering the cup body insertion plate chamber 6 is automatically controlled, which can not only ensure the completion of the detection reaction of the sample to be tested, but also effectively avoid excessive inflow of the sample to be tested, exceeding the detection line of the test strip 13 and causing the detection result to fail.

[0055] As an implementation manner, a limiting rib 19 is further provided at the bottom of the cup body insertion plate chamber 6.

[0056] By setting the limiting rib 19, it is helpful to fix and support the cup body insertion plate 11, ensure the unified position among different cup bodies, reduce the influence of the position difference of the cup body insertion plate 11 on the result, make the result more accurate. At the same time, keep a certain distance between the cup body insertion plate 11 and the front wall of the cup body insertion plate chamber 6, prevent the distance between the cup body insertion plate 11 and the front wall of the cup body insertion plate chamber 6 from being too small, and avoid the capillary action of the liquid, so that the liquid climbs too high along the gap and causes the detection result to fail.

[0057] As an implementation manner, a temperature label groove 20 for placing a temperature label is provided on the outer side wall of the cup body 2.

[0058] By setting the temperature label groove 20, it is convenient to visually display the temperature and prevent sample adulteration.

[0059] As an implementation manner, the extended insertion plate assembly 10 includes an extended insertion plate 21 inserted into the accommodation chamber 9. A plurality of extended slots 22 are provided on the extended insertion plate 21, and extended test strips 23 for detecting samples are provided in the extended slots 22. An extended label 24 for displaying the test strip result is attached to the surface of the extended test strip 23.

[0060] The above arrangement helps to assemble multiple extended test strips 23 on the extended plug board 21, and to conduct parallel tests on the samples to be tested at the same time, which helps to improve the detection accuracy and effectively save time. When testing the sample, it is only necessary to pull out the extended plug board 21 equipped with the extended test strip 23 from the accommodating cavity 9, and then insert it into the sample cavity 3 set inside the cup body 2, and after the extended test strip 23 absorbs an appropriate amount of the sample to be tested, take out the extended plug board 21, reinsert it into the accommodating cavity 9 and record the test result displayed on the extended test strip 23, and the test can be completed.

[0061] As an embodiment, a cup body male slot 25 is provided on one side of the cup body plug-in assembly 5 close to the expansion slot 8. A female slot 26 is provided on one side of the expansion slot 8 and at a position corresponding to the cup body male slot 25, and the female slot 26 is plug-connected with the cup body male slot 25. A male slot 27 adapted to the adjacent female slot 26 is provided on the other side of the expansion slot 8 away from the cup body male slot 25.

[0062] As an implementation manner, the number of the expansion slots 8 is one or more.

[0063] By setting up a plurality of independent expansion slots 8 to be plugged and connected to each other, more expansion test strips 23 can be tested simultaneously. At the same time, the cup body plugboard assembly 5 and all the expansion plugboard assemblies 10 are located in the same plane, which helps the external device to quickly read all the test strip test results and input them into the information system, effectively avoiding large errors in manual recording, and making the test results more accurate. In addition, the expansion slots 8 can be increased or decreased according to actual needs, and they are easy to install and disassemble, and the operation is simple. In addition, the type of expansion test strips 23 set on the expansion plugboard assembly 10 inserted into the expansion slot 8 can also be flexibly adjusted, so as to achieve the purpose of testing multiple items at the same time and further improve the detection efficiency.
