Description

Technical Field

[0001] This utility model relates to the field of medical testing technology, and in particular to a flushing testing device. Background Technology

[0002] Testing devices used to detect the presence of an analyte in a sample are widely used in hospitals and homes. These devices, applied to rapid diagnostics, contain one or more test strips, such as for early pregnancy testing and drug abuse testing. These rapid diagnostic devices are very convenient, providing results on the test strip in one minute, or at most ten minutes.

[0003] The detection process typically involves the following steps: after sampling, the sample is diluted and rinsed, then the diluted sample solution is sampled again and dropped onto a reagent plate, and finally the test results are observed. However, if the sample is not diluted and rinsed sufficiently, the composition of the final sample used for testing will be biased, which will affect the accuracy and reliability of the test results.

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1 As shown, the flushing detection device provided in this embodiment of the present invention includes: a housing 100, a sampling cover 200, a flusher 300, a test strip 400, and a liquid pusher 500; the flusher 300 is used to pick up the sample, and the flusher 300 is connected to the sampling cover 200; the sampling cover 200 is detachably connected to the housing 100, and the test strip 400 and the liquid pusher 500 are respectively installed on the housing 100; when the sampling cover 200 is connected to the housing 100, the flusher 300 is located between the test strip 400 and the liquid pusher 500.

[0024] When using the flushing detection device, first remove the sampling cap 200. The sampling cap 200 moves along with the flusher 300, which picks up the sample. Then, connect the sampling cap 200 to the housing 100, and place the flusher 300 between the test strip 400 and the pusher 500. Operate the pusher 500 to release the buffer solution. The buffer solution flushes the flusher 300 and dilutes the sample within it. The diluted sample then soaks the test strip 400, and the test result can be obtained by observing the test strip 400. Using the pusher 500 to release the buffer solution and flush and dilute the sample within the flusher 300 ensures that the sample is thoroughly flushed and diluted, improving the reliability of the diluted sample components and thus enhancing the accuracy and reliability of the test results.

[0025] In this embodiment of the invention, the flusher 300 is configured as a porous structure extending in the direction of the self-propelled liquid device 500 toward the test paper 400.

[0026] The buffer solution can be evenly distributed and rinsed through the porous structure, thereby ensuring that the sample is thoroughly rinsed and diluted, improving the reliability of the sample composition reaching 400 on the test strip, which is beneficial to improving detection accuracy.

[0027] like Figure 1 and Figure 2 As shown, an absorbent paper 600 is provided between the flusher 300 and the test paper 400. The diluted sample flowing out of the flusher 300 first wets the absorbent paper 600, and then the absorbent paper 600 slowly wets the test paper 400. This can avoid excessive dilution from wetting the test paper 400, which helps to improve the accuracy of the test results.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, the liquid pusher 500 includes: a liquid storage chamber shell 510, a sealing film 520, a push rod 530, and a plug 540; the liquid storage chamber shell 510 is installed inside the housing 100, and the sealing film 520 covers the end of the liquid storage chamber shell 510 facing the flusher 300; the plug 540 is fitted with the push rod 530, and the push rod 530 and the plug 540 are inserted into the liquid storage chamber shell 510 from the end away from the flusher 300, so that the plug 540 and the liquid storage chamber shell 510 are interference fit.

[0029] The reservoir shell 510 contains a buffer solution. Pushing the push rod 530 can cause the stopper 540 to squeeze the buffer solution inside the reservoir shell 510 until the sealing film 520 is broken, thus releasing the buffer solution by spraying it out, which can thoroughly rinse the sample in the flusher 300.

[0030] Furthermore, push rod 530 has a blade head that passes through plug 540. When push rod 530 is pushed, the blade head contacts sealing film 520, which can puncture or break sealing film 520. If push rod 530 is pushed further, buffer solution will be sprayed from the broken sealing film 520 to flusher 300.

[0031] See Figure 4 The inner wall of the liquid storage chamber shell 510 is provided with a first limiting part 511, and the push rod 530 is provided with a second limiting part 531 that is adapted to the first limiting part 511; when the push rod 530 is pushed, the second limiting part 531 slides away from the first limiting part 511.

[0032] The first limiting part 511 and the second limiting part 531 are configured as a protrusion and a groove, respectively. In the initial state, the first limiting part 511 and the second limiting part 531 cooperate to ensure the stability of the push rod 530 and prevent the push rod 530 from being accidentally moved.

[0033] like Figure 1 As shown, the housing 100 includes a lower cover 110 and an upper cover 120, with the lower cover 110 connected to the upper cover 120; the lower cover 110 is provided with a mounting groove 101 for mounting the test paper 400; the upper cover 120 is provided with a viewing port 102 opposite to the test paper 400 and a slot 103 for accommodating the flusher 300.

[0034] The lower cover 110 and the upper cover 120 can be fixed by means of snap-fit ​​connection, screw connection or other methods. Alternatively, one of the lower cover 110 and the upper cover 120 can be provided with a mounting post, and the other can be provided with a socket adapted to the mounting post. The mounting post is interference-fitted into the socket, thereby ensuring a stable connection between the lower cover 110 and the upper cover 120.

[0035] Furthermore, the lower cover 110 or the upper cover 120 is provided with a third limiting part 104 adapted to the liquid pusher 500, or both the lower cover 110 and the upper cover 120 are provided with a third limiting part 104 adapted to the liquid pusher 500. The liquid pusher 500 is engaged by the third limiting part 104, thereby ensuring that the liquid pusher 500 is securely installed relative to the housing 100.

[0036] Furthermore, the sampling cover 200 is provided with a window portion 201 opposite to the viewing port 102. When the sampling cover 200 is large, opening the window portion 201 on the sampling cover 200 can prevent the sampling cover 200 from obstructing the viewing port 102.

[0037] 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.
