Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a detection device. Background Art

[0002] In recent years, saliva has gained attention as a non-invasive testing sample in various fields such as disease diagnosis, psychological monitoring, and sports medicine. The components of saliva often correlate well with those of blood, and saliva samples have advantages such as being non-invasive and easy to collect, making them readily accepted by test subjects.

[0003] Existing saliva test kits include a test cup and a saliva collection component, with a test strip fixed to the side wall of the test cup. When testing is required, the saliva collection component is placed in the test cup, and force is applied to the component to expel saliva into the cup. The test strip located on the side wall of the test cup then analyzes a specific component in the saliva. However, the viscosity or foaminess of the saliva sample can lead to test failure. When the saliva collection component is squeezed, the flow rate and direction of the saliva at the moment of expulsion may cause the test strip to become submerged, resulting in test failure. Furthermore, existing testing devices perform direct detection after collection, failing to separate saliva collection and detection into steps, and cannot pre-determine the validity of the saliva sample. Utility Model Content

[0004] The purpose of this invention is to provide a detection device to alleviate the technical problems existing in the prior art, such as low success rate of saliva test kits due to sample foam or instantaneous submersion of the test strip upon squeezing, inability to separate the collection and testing of saliva samples into steps, and inability to predict whether the saliva sample is valid.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] In a first aspect, the detection device provided by this utility model includes a detection cup and a saliva collection component. The bottom wall of the detection cup is provided with an extrusion protrusion. The inner wall of the extrusion protrusion and the bottom wall form an extrusion area. The inner wall of the detection cup and the outer wall of the extrusion protrusion form a detection area. The bottom of the extrusion protrusion is provided with a flow channel connecting the extrusion area and the detection area.

[0007] The saliva collection component includes a sampling rod, one end of which is fitted with a sampling swab, and the end of the sampling rod with the sampling swab is inserted into the extrusion area;

[0008] A sealing ring is installed between the extrusion area and the sampling rod.

[0009] Furthermore, the sealing ring is fitted onto the outer wall of the sampling rod.

[0010] Furthermore, the outer wall of the sampling rod is provided with an installation groove, and the sealing ring is installed in the installation groove.

[0011] Furthermore, a filter element is installed in the extrusion area, and the filter element is located upstream of the flow channel along the sample flow direction.

[0012] Furthermore, the bottom wall of the filter element abuts against the bottom wall of the extrusion area, the side wall covers the flow channel, and is located below the sealing ring.

[0013] Furthermore, an indicator test strip is installed inside the sampling rod, and the indicator test strip abuts against the sampling swab.

[0014] Furthermore, the saliva collection component includes a sampling head, and the end of the sampling rod opposite to the sampling swab is connected to the sampling head;

[0015] The sampling head is connected to the top of the detection cup.

[0016] Furthermore, the top of the detection cup is provided with a first connecting structure, and the outer wall of the sampling head is provided with a second connecting structure, wherein the first connecting structure is connected to the second connecting structure.

[0017] Furthermore, the inner wall of the test cup has multiple mounting cavities for mounting test strips, each mounting cavity having an opening, and at least two of the mounting cavities having openings facing different directions.

[0018] Furthermore, the flow channel is provided in multiple ways, and the multiple flow channels are arranged at intervals along the circumference of the detection cup.

[0019] Based on the above technical solutions, the technical effects achievable by this utility model can be analyzed as follows:

[0020] The detection device provided by this utility model includes a detection cup and a saliva collection component. The bottom wall of the detection cup has an extrusion protrusion, the inner wall of which, together with the bottom wall, forms an extrusion area. A detection area is formed between the inner wall of the detection cup and the outer wall of the extrusion protrusion. A flow channel connecting the extrusion area and the detection area is provided at the bottom of the extrusion protrusion. The saliva collection component includes a sampling rod, one end of which is fitted with a sampling swab. The other end of the sampling rod with the sampling swab is inserted into the extrusion area. A sealing ring is installed between the extrusion area and the sampling rod. This detection device can be used to detect samples such as saliva. When the detection cup and saliva collection component are used together, the saliva collection component containing the sample is inserted into the extrusion area, and the saliva collection component is squeezed, causing the sample to be extruded from the sampling swab and flow through the flow channel into the detection area, where it contacts the test strip located within the detection area for detection. A sealing ring is installed between the extrusion area and the sampling rod to ensure airtightness during the extrusion process, avoid the problem of the test strip being flooded due to excessive sample flow rate, and improve the success rate of the test.

[0041] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0042] The detection device provided in this embodiment of the utility model includes a detection cup 100 and a saliva collection component 400. The bottom wall of the detection cup 100 is provided with an extrusion protrusion 110. The inner wall of the extrusion protrusion 110 and the bottom wall form an extrusion area 111. The inner wall of the detection cup 100 and the outer wall of the extrusion protrusion 110 form a detection area 120. The bottom of the extrusion protrusion 110 is provided with a flow channel 112 connecting the extrusion area 111 and the detection area 120. The saliva collection component 400 includes a sampling rod 410. A sampling swab 411 is installed at one end of the sampling rod 410. The end of the sampling rod 410 with the sampling swab 411 is used to insert into the extrusion area 111. A sealing ring 430 is installed between the extrusion area 111 and the sampling rod 410.

[0043] This detection device can be used to test samples such as saliva. The test cup 100 and the saliva collection component 400 work together. The saliva collection component 400, containing the test sample, is inserted into the extrusion area 111. Squeezing the saliva collection component 400 causes the test sample to be extruded from the sampling swab 411 of the saliva collection component 400, flowing through the flow channel 112 and into the detection area 120, where it comes into contact with the test strip 500 located in the detection area 120 for testing. A sealing ring 430 is installed between the extrusion area 111 and the sampling rod 410 to ensure airtightness during the extrusion process, preventing the test strip 500 from being flooded due to excessive sample flow rate, and improving the success rate of the test.

[0044] The structure and shape of the detection device are described in detail below:

[0045] In an optional embodiment of this utility model, the sealing ring 430 is sleeved on the outer wall of the sampling rod 410.

[0046] Specifically, the sampling rod 410 is welded to the sampling swab 411. Of course, other connection methods between the two should also be within the protection scope of this utility model embodiment.

[0047] The sealing ring 430 is fitted onto the outer wall of the sampling rod 410, which facilitates the installation and removal of the sealing ring 430.

[0048] In an optional embodiment of this utility model, the outer wall of the sampling rod 410 is provided with an installation groove 415, and the sealing ring 430 is installed in the installation groove 415.

[0049] The bottom outer wall of the sampling rod 410 is provided with an installation groove 415, and the sealing ring 430 is installed in the installation groove 415. The sealing ring 430 cooperates with the inner wall of the extrusion protrusion 110 to play a sealing role, which can ensure that the test sample can only pass through the filter element 200 and flow into the test area 120 under the action of air pressure.

[0050] In an optional embodiment of this utility model, a filter element 200 is installed in the extrusion area 111, and the filter element 200 is located upstream of the flow channel 112 along the sample flow direction.

[0051] Specifically, the filter element 200 is configured with a porous structure, which filters out viscous substances and also has an anti-foaming effect when the test sample flows through it. Furthermore, the test cup is made of transparent material to house the filter element 200 and the test paper 500, and to facilitate observation of the test results.

[0052] The saliva collection component 400, containing the test sample, is inserted into the extrusion area 111. Squeezing the saliva collection component 400 causes the test sample to be extruded from the sampling swab 411 of the saliva collection component 400. The sample then flows through the filter element 200 and the flow channel 112 into the detection area 120, where it comes into contact with the test strip 500 located in the detection area 120 for detection. The test cup 100 is used to mount the filter element 200 and the test strip 500, providing support and fixation. The filter element 200 filters out viscous substances from the test sample and also acts as an anti-foaming agent, improving the detection success rate of the device.

[0053] In one embodiment, the bottom wall of the filter element 200 abuts against the bottom wall of the extrusion area 111, and the side wall is covered with the flow channel 112 and located below the sealing ring 430.

[0054] In another embodiment, the filter element 200 is located below the sealing ring 430, its sidewall is connected to the inner wall of the extrusion area 111, and it covers the flow channel 112.

[0055] In an optional embodiment of this utility model, multiple flow channels 112 are provided, and the multiple flow channels 112 are arranged at intervals along the circumference of the detection cup 100.

[0056] Specifically, multiple channels 112 are evenly spaced along the circumference of the detection cup 100 to allow the filtered test sample to flow into the detection area 120.

[0057] In the optional embodiments of this utility model, see Figures 3 to 7 The saliva collection component 400 includes a sampling head 420, one end of a sampling rod 410 connected to the sampling head 420, and the other end of the sampling rod 410 equipped with a sampling swab 411; the end of the sampling rod 410 equipped with the sampling swab 411 is inserted into the extrusion area 111, and the sampling head 420 is connected to the top of the detection cup 100.

[0058] Specifically, see Figure 6 and Figure 7 The sampling head 420 has a larger cross-sectional area than the sampling rod 410. The top of the sampling rod 410 has a mounting portion 413, and the bottom of the sampling head 420 has a mounting groove 421. The mounting portion 413 is inserted into the mounting groove 421, and the mounting portion 413 is threaded, welded, or snap-fitted to the mounting groove 421. The sampling head 420 is used to fix the sampling rod 410 and cooperates with and seals against the detection cup 100. The sampling swab 411 is used to collect the test sample and store it in the internal cavity.

[0059] The sampling head 420 is used to fix the sampling rod 410 and cooperates with the test cup 100; the sampling rod 410 is used to fix the sampling swab 411 and can be inserted into the extrusion area 111; the sampling swab 411 is used to extract the test sample.

[0060] In an optional embodiment of this utility model, the top of the detection cup 100 is provided with a first connecting structure 130, and the outer wall of the sampling head 420 is provided with a second connecting structure 422, and the first connecting structure 130 is connected to the second connecting structure 422.

[0061] Specifically, see Figure 4 The outer wall of the sampling head 420 is provided with a second connecting structure 422, which is connected to the first connecting structure 130 at the top of the detection cup 100. Both the first connecting structure 130 and the second connecting structure 422 are set as baffles, and the first connecting structure 130 and the second connecting structure 422 are snapped together; or, both the first connecting structure 130 and the second connecting structure 422 are set as threaded protrusions, and the first connecting structure 130 and the second connecting structure 422 are threaded together.

[0062] In an optional embodiment of this utility model, an indicator test strip 412 is installed inside the sampling rod 410, and the indicator test strip 412 abuts against the sampling swab 411.

[0063] Specifically, see Figure 5 and Figure 7 The sampling rod 410 is made of transparent material and is designed as a hollow structure with an internal cavity 414 for installing the indicator test strip 412.

[0064] The indicator test strip 412 is installed in the cavity 414 of the sampling rod 410 and abuts against the sampling swab 411. When the sampling swab 411 absorbs the test sample to the point of saturation, the indicator test strip 412 will start to absorb the test sample and change color, thereby indicating that the test sample taken in the sampling swab 411 is sufficient, avoiding the problem of test failure due to insufficient test sample.

[0065] In an optional embodiment of this utility model, the inner wall of the test cup 100 has a plurality of mounting cavities for mounting the test strip 500. The mounting cavities are provided with openings, and at least two of the mounting cavities have openings facing different directions.

[0066] Specifically, see Figure 1 and Figure 2 The test strip 500 is inserted into the mounting cavity through an opening, with the opening facing either the top wall or the bottom wall of the test cup 100. The test strip 500 fits tightly into the mounting cavity and will not fall off from the opening. The test strip 500 is generally rectangular, and correspondingly, the cross-section of the mounting cavity is square.

[0067] Multiple mounting cavities facing different directions are used to mount different types of test strips 500; because at least two mounting cavities have different opening orientations, at least two test strips 500 have different types and mounting directions; after the test sample flows into the test area 120, the test strip 500 corresponding to the mounting cavity facing the bottom wall of the test cup 100 first contacts the test sample for testing, and then the test cup 100 is flipped so that the test strip 500 corresponding to the mounting cavity facing another direction contacts the test sample for testing; this allows for the design of different test item arrangements according to different testing needs; and the test strip 500 that contacts the test sample first can be used to test the validity of the test sample, realizing early detection of whether the test sample is valid.

[0068] In an optional embodiment of this utility model, the plurality of mounting cavities include a first mounting cavity and a second mounting cavity that are arranged parallel to each other along the circumference of the detection cup 100, and the opening orientation of the first mounting cavity is opposite to that of the second mounting cavity.

[0069] Specifically, the cross-sectional shapes of both the first and second mounting cavities are square, and the two ends of the first and second mounting cavities opposite to each other have openings. For example, the top of the first mounting cavity has an opening, and correspondingly, the bottom of the second mounting cavity has an opening; thus, the openings of the first and second mounting cavities face opposite directions. Of course, the collinearity of the axes of the first and second mounting cavities and the opposite orientation of their openings should also be within the protection scope of this utility model embodiment.

[0070] The test strips 500 placed in the first and second mounting cavities respectively can test the test samples at different stages or at different times, allowing for the design of different test item arrangements according to different testing needs.

[0071] In the optional embodiments of this utility model, see Figure 2 The multiple mounting cavities also include a third mounting cavity, which is located at one end of the first mounting cavity near the bottom wall of the detection cup 100; the opening orientation of the third mounting cavity is the same as that of the second mounting cavity.

[0072] Specifically, the third mounting cavity is used to install indicator color blocks, which can be used to indicate test results such as the pH value of the test sample. Of course, installing other test strips 500 in the third mounting cavity should also be within the protection scope of this utility model embodiment. More specifically, the inner wall of the test cup 100 has multiple mounting protrusions, including a first mounting protrusion 310, a second mounting protrusion 320, and a third mounting protrusion 330; the first mounting protrusion 310 and the second mounting protrusion 320 are arranged parallel to each other along the circumference of the test cup 100, and the first mounting protrusion 310 has a first mounting cavity, and the second mounting protrusion 320 has a second mounting cavity; the third mounting protrusion 330 is located at the end of the first mounting cavity near the bottom wall of the test cup 100, and the third mounting protrusion 330 has a third mounting cavity.

[0073] The third mounting cavity is located at the bottom of the test cup 100 and has an opening, which increases the placement space for the test strip 500 and thus increases the number of test items.

[0074] In an optional embodiment of this utility model, the test cup 100 includes a test strip fixing piece 300, one side of which is attached to the inner wall of the test cup 100, and the other side is provided with multiple mounting cavities.

[0075] Specifically, the test strip fixing piece 300 is configured as a blister pack or a plate-shaped support; of course, a structure in which the inner wall of the test cup 100 directly has an installation cavity should also be within the protection scope of this utility model embodiment. Taking the test strip fixing piece 300 configured as a blister pack as an example, the test strip fixing piece 300 includes a liner and multiple installation protrusions installed on the same side of the liner. The installation protrusions form an installation cavity. After the liner is bent, it is placed inside the test cup 100 and fits against the inner wall of the test cup 100.

[0076] Test strip holder 300 is used to hold test strip 500 in place.

[0077] The following is a detailed explanation of how to use this detection device:

[0078] When in use, the saliva collection component 400 is placed in the mouth to absorb the saliva. After 1 to 2 minutes of saliva absorption, the indicator strip 412 will change color after the sample is saturated, indicating that the sample amount is sufficient for testing.

[0079] The saliva collection component 400 is directly fitted onto the test cup 100 and pressed. During the pressing process, the sampling swab 411 is compressed, and the test sample inside is squeezed out. At this time, the sealing ring 430 of the sampling rod 410 has already cooperated and sealed with the inner wall of the extrusion protrusion 110. Under atmospheric pressure, the squeezed sample can only flow into the test area 120 through the filter element 200 and the flow channel 112. After being filtered by the filter element 200, the test sample enters the test area 120 and comes into contact with the test paper 500 pre-installed in the third mounting cavity adjacent to the bottom of the cup and the test paper 500 installed in the second mounting cavity with the opening direction facing the bottom of the cup. The results are then interpreted. If the test results are normal, the device is inverted, and the test sample comes into contact with the test paper 500 installed in the first mounting cavity with the opening direction facing the mouth of the cup, and the test to be performed begins. The test results are interpreted after a certain period of time.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
