[0041] Example 1
[0042] like Figure 1 - Figure 5 As shown, the saliva cup provided by this utility model can be used for the detection of saliva samples.
[0043] Its specific structure includes: cup body 1, cup lid 2, and internal sealing element.
[0044] The cup body 1 has a first cavity and a second cavity inside. The first cavity has a first opening, and the second cavity has a second opening. In this embodiment, a first tube 5 is disposed inside the cup body 1. The first tube 5 extends vertically and can be integrally formed with the cup body 1. The lower end of the first tube 5 is connected to the bottom surface of the cup body 1, that is, the lower end opening of the first tube 5 is closed. The upper end opening of the first tube 5 is lower than the total opening and forms a first opening to facilitate the smooth flow of liquid in the first tube 5 when the cup body 1 is inverted. The internal space of the first tube 5 forms a first cavity for holding the test solution. The space between the outer wall of the first tube 5 and the inner wall of the cup body 1 forms a second cavity.
[0045] like Figure 3 As shown, a bushing 11 with internal threads is provided on the cup body 1, and a screw 10 with external threads is provided on the cup lid 2. The screw 10 is threadedly connected to the bushing 11 so that the cup lid is connected to the cup body 1. The bushing 11 is arranged side by side with the first tube 5.
[0046] like Figure 3 - Figure 5 As shown, in this embodiment, a second tube 9 is provided on the cup lid 2. The top end of the second tube 9 is connected to the cup lid 2, and the top opening of the second tube 9 is closed, while the bottom opening of the second tube 9 is open. When the cup lid 2 and the cup body 1 are rotated into place, the bottom opening of the second tube 9 is directly opposite the first opening, so that the bottom of the second tube 9 is pressed against the internal sealing element.
[0047] Here, "rotation in place" refers to tightening the cup lid 2 until it cannot be rotated further. The number of rotations between the cup lid 2 and the cup body 1 can be set to three, four, or five turns, etc. A stop structure can be set at the internal or external thread. When the preset number of rotations is reached, further rotation is impossible, thereby achieving the positioning and alignment of the first tube 5 and the second tube 9. The first opening and the second opening are connected to form an independent cavity isolated from the second cavity. Figure 3 The state shown.
[0048] Before testing, the bottom of the second tube 9 can be pressed against the internal seal to improve its sealing performance. During testing, open the cup lid 2, remove the internal seal, place the sample into the first tube 5, close the cup lid 2 and rotate it into place. The first tube 5 and the second tube 9 are now connected and sealed. At this point, the saliva cup can be shaken to ensure the sample is in full contact with the test solution. After shaking, in... Figure 3 In the state shown, rotate the cup lid 2 to 180° so that the first opening and the second opening are completely misaligned. Then invert the saliva cup so that the liquid in the first tube 5 can flow into the cup lid 2 and come into contact with the test strip 6.
[0049] At least one of the cup body 1 and the cup lid 2 is provided with a sealing ring 4. The sealing ring 4 is used to fill the gap between the cup body 1 and the cup lid 2 when the cup lid 2 closes the main opening. In this embodiment, the sealing ring 4 can be set in an annular groove on the top surface of the cup body 1 (not shown in the figure). The device has good sealing performance, is not easy to leak, and improves the safety of using the saliva cup.
[0050] In one feasible solution, the internal seal can be a plug, which can be threaded or interference-fitted to the first opening. Before testing, the plug can be rotated off or pulled out directly to expose the first opening. In this embodiment, the internal seal is a sealing film 3 that fits against the edge of the first opening, such as an aluminum foil film. The sealing film 3 is sealed by heat sealing to prevent the test solution from evaporating during storage. Figure 3 As shown.
[0051] The second cavity contains a test strip 6, which can be directly attached to the inner wall of the cup body 1. In this embodiment, as shown... Figure 3 As shown, the test strip 6 is fixed to the strip holder 7 by a mounting pin. A slot 8 is provided in the second cavity of the cup body 1. The slot 8 is used to engage with the strip holder 7 to prevent the strip holder 7 from moving relative to the cup body 1.
[0052] The cup body 1 has at least a partially transparent area, which is used to observe the internal condition of the second cavity, that is, to observe the changes of the test strip 6. In this embodiment, the entire outer wall of the cup body 1 is made transparent. In other feasible solutions, only the area aligned with the test strip 6 can be made transparent.
[0053] In this embodiment, the test strip 6 and the test solution are separated by the sealing film 3 before use, achieving dry and wet separation. Simultaneously, the sealing ring 4 between the lid 2 and the cup body 1 enhances the seal. The saliva cup is easy to operate. The second chamber holds more test strips 6 and the solution required for testing, allowing for the simultaneous testing of multiple items. Operation is convenient; inverting the saliva cup enables timed testing.
[0054] Example 2
[0055] like Figure 6 and Figure 7 As shown, the difference from Embodiment 1 is that in this embodiment, the cup lid 2 has a top plate and a side wall arranged around the top plate, and the outer wall of the side wall is provided with anti-slip texture.
[0056] In this embodiment, the side wall has an internal thread, and the outer wall of the cup body 1 has an external thread. The external thread is used to connect with the internal thread on the side wall, and the main opening is opened and closed by rotating the cup lid 2.
[0057] In this embodiment, as Figure 7 As shown, the sealing ring 4 is disposed in the annular groove on the bottom surface of the top plate of the cup lid 2. The annular groove and the sealing ring 4 fit together tightly. The sealing ring 4 is used to fill the gap between the cup body 1 and the cup lid 2 when the cup lid 2 closes the main opening, so as to prevent the liquid inside the cup body 1 from flowing out when the cup body 1 is inverted.
[0058] like Figure 7 As shown, the cup lid 2 may be provided with a rim 12 surrounding the second tube 9. The projection of the first opening onto the cup lid 2 is located inside the rim 12, and the test strip 6 is located radially outside the rim 12. The rim 12 can prevent overflow. In order to fully dissolve the saliva sample, the test solution in the first tube 5 can be filled with a large amount. During the test, after the saliva cup is inverted, some of the test solution will flow into the inside of the rim 12, and some will overflow from the rim 12 and come into contact with the test strip 6, thereby avoiding excessive contact between the test solution and the test strip 6 and preventing the test strip 6 from being soaked.
[0059] Example 3
[0060] like Figure 8 and Figure 9 As shown, the difference from embodiments 1 and 2 is that in this embodiment, the cup lid 2 is provided with a through hole 13 that penetrates its upper and lower surfaces, and the through hole 13 is connected to the top opening of the second tube 9.
[0061] A saliva-soaked cotton swab can be inserted through the through-hole 13. To use, first open the cup lid 2, remove the internal seal, then close the lid 2 and rotate it to the correct position. Insert the sample-soaked cotton swab into the first tube 5 through the through-hole 13. If the internal seal is aluminum foil, the lid 2 can be punctured directly through the through-hole 13 without opening the lid first, and then the sample-soaked cotton swab can be inserted into the first tube 5. After sufficient reaction, rotate the lid 2 until the first and second openings are completely misaligned. Invert the saliva cup; the liquid in the first tube 5 flows into the bottom of the lid 2 (the amount of test solution is limited and will not overflow from the second tube 9), and the solution comes into contact with the test strip 6.
[0062] 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.
