Abstract
Description
Technical Field
[0001] This utility model relates to the field of sample sampling and testing technology, and in particular to a sampling and testing device. Background Technology
[0002] With the continuous innovation and breakthroughs in biological detection technology, the application scope of sampling and testing pen-type devices is constantly expanding in fields such as medical diagnosis, environmental monitoring, and food safety, and their importance is becoming increasingly prominent. Traditional sampling and testing pen-type devices mainly consist of two core components: a sampling rod and a cannula. The standard operating procedure can be summarized as follows: after sample collection, the operator removes the cannula and then inserts the sampling rod containing the sample into a solution containing buffer solution for plate testing. This design concept has significant advantages in simplifying the sampling and testing process, and its convenience allows it to adapt to various application scenarios.
[0003] However, through in-depth market application analysis and practical feedback, several technical bottlenecks urgently need to be addressed: First, the sample cannot be fully flushed during the detection process, leading to sample residue; second, the sample and buffer solution cannot achieve ideal mixing and lysis effects. These factors significantly impact the accuracy and reliability of the detection results. More importantly, current market testing pens generally suffer from a limited number of detection targets, severely restricting their breadth and depth of application in complex testing needs. These technical deficiencies not only affect detection efficiency but also limit the wider application of this device. Utility Model Content

[0020] The pen tube component includes an insertion body and a connecting body;

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0048] 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.
[0049] like Figure 1 As shown, the sampling and testing device provided in this embodiment includes: a pen body component 100, a pen tube component 200, a pen holder component 300, and a test strip 400; the inner wall of the pen body component 100 is provided with a plurality of mounting slots 131, which are used to install the test strip 400. In addition, in order to facilitate the user to observe the reading results of the test strip 400, the pen body component 100 is made transparent as a whole, so that the reading of the test strip 400 can be observed intuitively.
[0050] The end face of the pen body component 100 has a sampling part 110. The sampling part 110 can be specifically configured as a sampling sponge. The sampling part 110 can acquire a sample. During sampling, the sampling part 110 directly contacts the sample to acquire the sample.
[0051] The pen tube component 200 is connected to the pen holder component 300. The pen holder component 300 contains a buffer solution and is provided with a sealing film 310. The sealing film 310 is used to seal the buffer solution inside the pen holder component 300 to prevent the buffer solution from leaking out of the pen holder component 300 when it is not in use.
[0052] The pen tube component 200 is a hollow structure, allowing the pen body component 100 to be inserted. When sampling is completed and testing is required, the sampling part 110 can penetrate the pen tube component 200, pierce the sealing film 310, and extend into the pen holder component 300. Since the sampling part 110 extends into the space containing the buffer solution inside the pen holder component 300, the buffer solution overflows and washes the sampling part 110. The mixture of buffer solution and sample enters the pen body component 100 through the pen tube component 200 and comes into contact with the test strip 400.
[0053] The sampling and detection device provided in this embodiment has multiple mounting slots 131 on the inner wall of the pen body component 100. Each mounting slot 131 can install test strips 400, thus allowing multiple test strips 400 to be installed, enabling the detection of multiple targets. A sampling section 110 is formed on the end face of the pen body component 100. The sampling section 110 is used to obtain the sample. After sampling, the pen body component 100 is inserted into the pen tube component 200, so that the sampling section 110 pierces the sealing film 310 and extends into the pen holder component 300. The buffer solution in the pen holder component 300 is flushed and overflowed by the sampling section 110. The mixture of buffer solution and sample enters the pen body component 100 through the pen tube component 200 and comes into contact with the test strips. The test strips 400 run on the plate for detection, realizing that the sample and buffer solution are fully flushed and mixed. This alleviates the technical problem in the prior art that the sampling and detection pen does not mix the sample and buffer solution sufficiently, affecting the detection accuracy and preventing the detection of more targets.
[0054] Regarding the shape and structure of the pen body component 100, specifically:
[0055] like Figure 2 , Figure 3 As shown, the pen body component 100 includes a pen body shell 120. The shape of the pen body shell 120 can be set to cylindrical or square. Since the test paper 400 is usually long and narrow, the pen body shell 120 is preferably set to square.
[0056] The end of the pen body shell 120 near the pen tube member 200 extends in the direction near the pen tube member 200 and forms a connecting protrusion. The end of the connecting protrusion near the pen tube member 200 is connected to the sampling part 110.
[0057] In an optional embodiment, the pen body shell 120 is provided with a connecting hole 121 on the end face near the pen tube component 200. The number of connecting holes 121 can be set to multiple, and the multiple connecting holes 121 are arranged symmetrically. The connection hole 121 enables communication between the interior of the pen tube component 200 and the interior of the pen body shell 120, so that the liquid in the pen tube component 200 can enter the pen body shell 120, ensuring that the liquid can smoothly enter the pen body shell 120 and fully contact the test paper 400.
[0058] Alternatively, a through hole can be made in the middle of the sampling section 110 to facilitate the flow of the buffer solution into the pen body housing 120 while the sampling section 110 is being flushed.
[0059] In an optional embodiment, the pen body component 100 further includes a test strip mounting structure 130; the test strip mounting structure 130 is disposed within the pen body housing 120, and the test strip mounting structure 130 has a plurality of mounting grooves 131. Specifically, the test strip mounting structure 130 is specifically configured as a blister pack, on which a through mounting groove 131 is formed. The test strip 400 is located within the mounting groove 131, and in order to ensure that the test strip 400 can contact the mixture of buffer solution and sample liquid, the end of the test strip 400 located within the mounting groove 131 near the pen tube component 200 protrudes from the groove opening of the mounting groove 131, so that the test strip 400 protrudes from the mounting groove 131.
[0060] Regarding the shape and structure of the pen tube component 200, specifically:
[0061] like Figure 4 The pen tube component 200 is an integrally formed structure, including an insertion body 210 and a connecting body 220; the insertion body 210 and the connecting body 220 are connected to each other, and both the insertion body 210 and the connecting body 220 are set as hollow structures for the pen body component 100 to be inserted.
[0062] Specifically, in order to fit the shape of the pen body shell 120, the insertion body 210 is set as a square structure with a through-center, and in order to fit the shape of the pen holder component 300, the connecting body 220 is set as a cylindrical structure.
[0063] In an optional embodiment, the connecting body 220 and the pen holder component 300 are detachably connected. The detachable connection method can be a snap-fit connection or a threaded connection. The specific connection method between the connecting body 220 and the pen holder component 300 can be selected according to the specific application.
[0064] Regarding the shape and structure of the pen holder component 300, specifically:
[0065] like Figure 5 As shown, the pen holder component 300 is an integrally molded structure. The pen holder component 300 includes a connecting part 320 and a gripping part 330. The connecting part 320 and the gripping part 330 are connected to each other. The connecting part 320 extends into the connecting body 220 and is detachably connected to the connecting body 220. The gripping part 330 is used by the user for gripping and use.
[0066] The middle part of the connecting part 320 is recessed in the direction away from the pen tube component 200 to form a holding groove 322. The holding groove 322 is used to hold the buffer solution. The sealing film 310 is used to seal the opening of the holding groove 322 to prevent the buffer solution from flowing out of the holding groove 322. After sampling is completed, the sampling part 110 punctures the sealing film 310 and extends into the holding groove 322. As the sampling part 110 extends into the holding groove 322, the buffer solution overflows into the pen tube component 200 after contacting the sampling part 110, and then enters the pen body component 100 to contact the test strip 400 for plate testing.
[0067] In addition, an internal thread section 221 is provided on the inner wall of the connecting body 220, and an external thread section 321 is provided on the outer wall of the connecting part 320. The internal thread section 221 and the external thread section 321 cooperate with each other to realize the threaded connection between the connecting part 320 and the connecting body 220.
[0068] Based on the above, such as Figure 6 As shown, in an optional embodiment, the sampling and detection device further includes a pen cap component 500; the pen body component 100 has an opening at one end away from the pen tube component 200, and the pen cap component 500 is used to cover the pen body component 100 to block the opening of the pen body component 100 and prevent liquid inside the pen body component 100 from flowing out of the opening.
[0069] In an optional embodiment, the pen cap member 500 protrudes toward the pen body member 100 to form an insertion protrusion 510. When the pen cap member 500 is placed on the pen body member 100, the insertion protrusion 510 extends into the pen tube member 200. The side of the insertion protrusion 510 has a connecting slope 511. The connecting slope 511 abuts against the inner wall of the pen tube member 200. The connecting slope 511 and the pen tube member 200 have a certain frictional force, thereby connecting the insertion protrusion 510 into the pen tube member 200.
[0070] The sampling and detection device provided by this utility model has the following advantages:
[0071] 1. By providing multiple mounting slots 131 on the inner wall of the pen body component 100, each mounting slot 131 can independently install the test strip 400, so that the device can simultaneously accommodate multiple test strips 400, thereby realizing the synchronous detection of multiple targets.
[0072] 2. When the pen body component 100 is inserted into the pen tube component 200, the sampling part 110 can automatically pierce the sealing film 310 on the pen holder component 300 and extend into it. The buffer solution inside the pen holder component 300 is released under the pressure of the sampling part 110 and washes the sample on the sampling part 110, ensuring that the sample and buffer solution can be fully mixed.
[0073] 3. The mixture of buffer solution and sample flows into the pen body component 100 through the pen tube component 200 and comes into contact with the pre-installed test strip 400 to complete the test plate detection. Throughout the process, it is in a dynamic mixing state, thereby maximizing the mixing uniformity of sample and buffer solution and detection sensitivity.
[0074] 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.
