Description

Technical Field

[0001] This utility model relates to the field of sampling and detection technology, and in particular to an integrated device for saliva collection and detection. Background Technology

[0002] With the development of medical diagnostic technology, saliva-based testing methods have been widely used due to their simplicity, speed, and high sensitivity. Currently, in the field of rapid diagnostics, especially in home self-testing and point-of-care testing, plate-based testing devices are one of the most common testing tools. These devices typically consist of a sampling element and a test plate, which are often packaged separately in practice. During use, the user first needs to collect a sample using the sampling element and then place it on the test plate for testing. Due to this design, the sampling element and test plate are usually disposed of separately after use, ultimately leading to resource waste. Furthermore, the separate design of the sampling element and test plate also increases the risk of virus transmission, especially when handling biological samples; improper handling may lead to sample leakage, thereby increasing the possibility of cross-infection. Utility Model Content

[0003] The purpose of this invention is to provide an integrated saliva collection and testing device to alleviate the technical problem that the sample collection and testing are separate designs in the prior art, which increases the risk of virus transmission.

[0004] The saliva collection and detection integrated device provided by this utility model includes: an upper plate, a lower plate, a sampling plate, a sliding cover, and a sampling head;

[0005] The upper plate is provided with a receiving groove for placing the sampling plate;

[0006] The lower plate is used to place the test element, and the upper plate is placed on the lower plate;

[0007] The sampling plate is equipped with a sampling head for absorbing samples, and the sampling plate is rotatably connected to the lower plate so that the sampling plate can rotate relative to the lower plate;

[0008] The sliding cover is slidably connected to the upper plate, and the sliding cover can abut against the sampling plate to confine the sampling plate in the receiving groove and squeeze the sampling head so that the sample runs on the test element for testing.

[0009] In an optional implementation,

[0010] The upper plate has a sample inlet for the sampling head to pass through, so that the sample squeezed out by the sampling head in the sample inlet can come into contact with the test element.

[0011] In an optional implementation,

[0012] The upper plate has mounting protrusions;

[0013] The sliding cover has slots;

[0014] The mounting protrusion extends into the slot and is movable within the slot so that the sliding cover can move relative to the upper plate.

[0015] In an optional implementation,

[0016] The upper plate has a pop-out structure, which is used to give the sampling plate a tendency to rotate away from the receiving groove.

[0017] In an optional implementation,

[0018] The lower plate has a notch at its end, and the sidewall of the notch is provided with a mounting shaft;

[0019] The sampling plate is provided with a rotating shaft hole, and the mounting shaft extends into the rotating shaft hole so that the sampling plate can rotate around the mounting shaft.

[0026] In an optional implementation,

[0027] The sampling plate has a locking protrusion at the end away from the rotating shaft hole. The locking protrusion is inclined so that when the sliding cover abuts against the locking protrusion, the sliding cover can press down on the sampling plate.

[0028] In an optional implementation,

[0029] The sampling plate is provided with a viewing window, and the upper plate is provided with an observation window. The viewing window and the observation window are provided in correspondence, and the viewing window and the observation window are used to observe the test results of the test element.

[0030] The saliva collection and testing integrated device provided by this utility model involves taking a saliva sample by placing a sampling head on a sampling plate into the mouth. After sampling, the sampling plate is rotated into the receiving groove on the upper plate. Then, the sliding cover slides relative to the upper plate, causing the sliding cover to abut against the sampling plate and press the sampling plate tightly. This squeezes the sampling head, causing the saliva sample drawn by the sampling head to flow out and contact the test element on the lower plate, thus enabling plate testing. This alleviates the technical problem of the existing technology where the sample collection and testing are separate designs, which increases the risk of virus transmission.

[0042] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0043] like Figure 1 , Figure 2As shown, the saliva collection and detection integrated device provided in this embodiment includes: an upper plate 100, a lower plate 200, a sampling plate 300, a sliding cover 400, and a sampling head 500. The upper plate 100 is provided with a receiving groove 110 for placing the sampling plate 300. Specifically, the receiving groove 110 is recessed in the top surface of the upper plate 100 so that after the sampling plate 300 is placed in the receiving groove 110, the sampling plate 300 is flush with the top surface of the upper plate 100, which is more aesthetically pleasing. The lower plate 200 is used to place the testing element 600, which can test saliva samples and display the test results. The upper plate 100 covers the lower plate 200, and the testing element 600 is located between the upper plate 100 and the lower plate 200. A sampling head 500 for aspirating samples is installed on the sampling plate 300. The sampling plate 300 is rotatably connected to the lower plate 200 so that the sampling plate 300 can rotate relative to the lower plate 200, thereby controlling the switching between sampling and testing. When sampling is required, the user drives the sampling plate 300 to rotate away from the lower plate 200 and inserts the sampling head 500 on the sampling plate 300 into the mouth to aspirate saliva. After sampling, the user drives the sampling plate 300 to rotate closer to the lower plate 200 and places the sampling plate 300 in the receiving groove 110. Since the sliding cover 400 is slidably connected to the upper plate 100, the user slides the sliding cover 400 so that the sliding cover 400 abuts against the sampling plate 300, restricting the sampling plate 300 in the receiving groove 110 and squeezing the sampling head 500 so that the sample runs on the test element 600 for testing.

[0044] The saliva collection and testing integrated device provided in this embodiment collects saliva samples by placing the sampling head 500 on the sampling plate 300 into the mouth. After sampling, the sampling head 500 is rotated into the receiving groove 110 on the upper plate 100. Then, the sliding cover 400 slides relative to the upper plate 100, so that the sliding cover 400 abuts against the sampling plate 300, pressing the sampling plate 300 tightly and squeezing the sampling head 500. This causes the saliva sample collected by the sampling head 500 to flow out and contact the test element 600 on the lower plate 200, thus enabling plate-to-plate testing. This alleviates the technical problem in the prior art where the sample collection and testing are separate designs, which increases the risk of virus transmission.

[0045] Regarding the structure and shape of the upper plate 100, specifically:

[0046] like Figure 3 As shown, the upper plate 100 has a sample inlet 120, which is provided through the upper plate 100 so that the sampling head 500 can pass through the sample inlet 120. After the sampling plate 300 is placed on the upper plate 100, the sample squeezed out by the sampling head 500 in the sample inlet 120 can contact the test element 600, thereby performing plate running test.

[0047] The upper plate 100 has mounting protrusions 130, such as Figure 6 As shown, the sliding cover 400 has a slot 410, and the mounting protrusion 130 extends into the slot 410. Since the diameter of the slot 410 is larger than the outer diameter of the mounting protrusion 130, the mounting protrusion 130 can move in the slot 410 so that the sliding cover 400 can move relative to the upper plate 100.

[0048] In addition, the mounting protrusion 130 has a sloping structure, and the height of the mounting protrusion 130 gradually increases in the direction of the receiving groove 110. During the process of mounting the sliding cover 400 onto the upper plate 100, the mounting protrusion 130 can pass over the sliding cover 400 and enter the slot 410. After the mounting protrusion 130 extends into the slot 410, the vertical surface of the mounting protrusion 130 can abut against the inner wall of the slot 410, thereby preventing the sliding cover 400 from falling off the upper plate 100.

[0049] In an optional embodiment, the upper plate 100 has a pop-out structure 140, which is used to give the sampling plate 300 a tendency to rotate away from the receiving groove 110. Specifically, the pop-out structure 140 is a plastic part with a certain degree of elasticity, and the sampling plate 300 is popped out by the elastic force generated by the deformation of the plastic part.

[0050] Regarding the structure and shape of the lower plate 200, specifically:

[0051] like Figure 4 As shown, the lower plate 200 has a notch at its end, and the side wall of the notch is provided with a mounting shaft 210. The sampling plate 300 is provided with a rotating shaft hole 310, and the mounting shaft 210 extends into the rotating shaft hole 310, so that the sampling plate 300 can rotate around the mounting shaft 210.

[0052] In an optional embodiment, the lower plate 200 is provided with a limiting groove 220, and the test element 600 is installed in the limiting groove 220. Specifically, a baffle is provided on the lower plate 200, and the baffle is provided on three sides to form the limiting groove 220. The test element 600 is placed into the limiting groove 220, thereby restricting the movement of the test element 600 and confining the test element 600 on the lower plate 200.

[0053] In an optional embodiment, the lower plate 200 is provided with a sample collection groove 230, which is used to collect the sample squeezed out from the sampling head 500. When the sampling plate 300 is covered in the receiving groove 110, the sampling head 500 on the sampling plate 300 is located in the sample collection groove 230. The sliding cover 400 squeezes the sampling plate 300, and the sampling head 500 is squeezed. The saliva sample sucked by the sampling head 500 flows into the sample collection groove 230. The test end of the test element 600 is located in the sample collection groove 230. The test element 600 contacts the sample and performs plate running test.

[0054] Regarding the structure and shape of the sampling plate 300, specifically:

[0055] like Figure 5 As shown, a sampling mounting groove 320 for mounting a sampling head 500 is provided on the side of the sampling plate 300 near the receiving groove 110. The sampling head 500 is installed in the sampling mounting groove 320 and is located on the side facing the lower plate 200. An indicator mounting groove 330 is provided at the bottom of the sampling mounting groove 320. The indicator mounting groove 330 is used to install a sample saturation indicator element 700. The sample saturation indicator element 700 is used to indicate whether the sample sampling volume is saturated.

[0056] In an optional embodiment, a locking protrusion 340 is provided at the end of the sampling plate 300 away from the pivot hole 310. The locking protrusion 340 is inclined. During the sliding movement of the sliding cover 400, the sliding cover 400 abuts against the locking protrusion 340. Since the locking protrusion 340 is an inclined structure, the sliding cover 400 can press down on the sampling plate 300 during the sliding process.

[0057] In an optional embodiment, the sampling plate 300 is provided with a viewing window 350, and the upper plate 100 is provided with an observation window 150. The viewing window 350 and the observation window 150 are provided correspondingly. Alternatively, the viewing window 350 and the observation window 150 can be replaced with transparent material for observing the test results of the test element 600.

[0058] The method of using the integrated saliva collection and detection device provided by this utility model is as follows:

[0059] 1. Slide the sliding cover 400 down until it opens. At this time, the mounting protrusion 130 abuts against the slot 410, and the protrusion 340 is exposed. Under the action of the pop-up structure 140, the sampling plate 300 is popped up to a certain height.

[0060] 2. Fold the sampling plate 300 to the appropriate position, place the sampling head 500 into the mouth to draw up the saliva sample, and observe the color of the sample saturation indicator 700. When the sample saturation indicator 700 changes color, the sampling process is over.

[0061] 3. Fold the sampling plate 300 into the sampling plate 300 receiving groove 110, slide the sliding cover 400 upward to lock the sampling plate 300, squeeze the sampling head 500, and the flowing saliva sample comes into contact with the test element 600. Place the device on the table, wait for the test to be completed, and interpret the test results.

[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.
