Abstract
Description
Technical Field
[0001] This utility model relates to the field of sample sampling reaction detection technology, and in particular to a sample sampling reaction detection pen. Background Technology
[0002] With the continuous development of biological detection technology, the application of sampling and testing pen-type devices in fields such as medical diagnosis, environmental monitoring, and food safety is constantly expanding. Traditional sampling and testing pen-type devices mainly consist of two core components: a sampling rod and a cannula. The standard operating procedure includes: after sampling, removing the cannula, and inserting the sampling rod containing the sample into a solution containing buffer solution for plate testing. Although this design has advantages in terms of ease of operation, it still has several technical limitations in practical applications.
[0003] First, in terms of saliva sample collection, traditional testing pens lack real-time sample volume assessment capabilities, making it impossible to effectively determine whether the collected saliva sample meets the minimum required volume for testing. This directly affects the accuracy of the test results. Second, in the sample processing stage, traditional testing pens suffer from insufficient sample rinsing, and the sample and buffer solution are difficult to mix thoroughly and effectively. These factors all negatively impact the accuracy and reliability of the test results. Furthermore, existing testing pens on the market generally have a limited number of detection targets, which to some extent restricts their application value in multi-target detection scenarios.
[0004] The existence of these technical limitations highlights that the design and functionality of sampling and detection pen-type devices still need further optimization and improvement to meet the growing demand for accurate detection. Utility Model Content
[0005] The purpose of this invention is to provide a sampling reaction detection pen to alleviate the technical problems of poor detection accuracy and inability to detect more targets in traditional detection pens in the prior art.
[0006] The sampling reaction detection pen provided by this utility model includes: a pen body component, a pen tube component, a pen base component, a detection component, and a fixing component;
[0007] The pen body component is equipped with a sampling component, which is used to acquire samples;
[0008] The fixing component is disposed inside the pen body component, and the fixing component has multiple slots for fixing the test component.

[0010] The detection component is disposed on the pen body component, and the detection component is used to detect the sampling amount of the sampling component;
[0011] The pen tube component is configured to allow the pen body component to be inserted, so that the sampling component punctures the sealing film and contacts the buffer solution, and so that the buffer solution passes through the pen tube component into the pen body component and contacts the test component.
[0012] In an optional implementation,
[0013] An insertion protrusion is formed on the end face of the pen body component near the pen tube component, and the sampling component is sleeved on the insertion protrusion.

[0016] In an optional implementation,

[0018] The sampling component blocks the opening of the slot.
[0019] In an optional implementation,
[0020] The pen body component has a connecting hole on its end face near the pen tube component. The connecting hole is used to connect the pen body component with the pen tube component so that liquid in the pen tube component can enter the pen body component through the connecting hole.
[0021] In an optional implementation,
[0022] The pen holder component includes a grip and a liquid holding part;
[0023] The grip portion is connected to the liquid holding portion, and the liquid holding portion has a receiving groove with an opening facing the pen tube component, the receiving groove being used to hold the buffer solution;

[0036] The sampling reaction detection pen provided by this utility model has a sampling component set on the pen body to obtain a saliva sample. The detection component determines whether the amount of saliva sample is sufficient. After sufficient sampling is completed, the pen body is inserted into the pen tube component, so that the sampling component pierces the sealing film and extends into the pen holder component to fully contact the buffer solution.

[0049] 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.
[0050] like Figure 1 , Figure 2 As shown, the sampling reaction detection pen provided in this embodiment includes: a pen body component 100, a pen tube component 200, a pen base component 300, a detection component 400, and a fixing component 500; the pen body component 100 is provided with a sampling component 110, which is specifically configured as a sampling sponge. The user holds the pen body component 100 so that the sampling component 110 is inserted into the mouth of the person being sampled, and the sampling component 110 is used to obtain a sample.
[0051] The fixing component 500 is disposed within the pen body component 100. The fixing component 500 has multiple slots 510 for fixing the test component. The test component is specifically configured as a test paper. Each slot 510 can hold one test paper.
[0052] 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 membrane 311 to confine the buffer solution within the pen holder component 300. The sealing membrane 311 is used to prevent the buffer solution from flowing out of the pen holder component 300 when the detection pen is not in use.
[0053] The detection component 400 is disposed on the pen body component 100. The detection component 400 is used to detect the sampling amount of the sampling component 110. The detection component 400 is specifically configured as a color developing bar. When the test component is filled with saliva sample, the saliva sample comes into contact with the color developing bar, and the color developing bar develops color. The user knows the saliva sample collection by observing the color development bar.
[0054] The pen tube component 200 is configured to allow the pen body component 100 to be inserted so that the sampling component 110 pierces the sealing film 311 to contact the buffer solution, and so that the buffer solution passes through the pen tube component 200 into the pen body component 100 to contact the test component.
[0055] The sampling reaction detection pen provided in this embodiment uses a sampling component 110 on the pen body component 100 to obtain a saliva sample. The detection component 400 determines whether the amount of saliva sample is sufficient. After sufficient sampling is completed, the pen body component 100 is inserted into the pen tube component 200, so that the sampling component 110 pierces the sealing film 311 and extends into the pen holder component 300 to fully contact the buffer solution. As the buffer solution holding space is squeezed by the sampling component 110, the buffer solution mixed with the sample enters the pen body component 100 through the pen tube component 200 and comes into full contact with the test component. The test component performs a plate test. Furthermore, since the fixing component 500 is provided with multiple slots 510, each slot 510 can fix one test component, thereby fixing multiple test components and realizing the detection of multiple targets. This alleviates the technical problems of poor detection accuracy and inability to detect more targets in traditional detection pens in the prior art.
[0056] Regarding the structure and shape of the pen body component 100, specifically:
[0057] like Figure 3 As shown, in an optional embodiment, the pen body component 100 has an insertion protrusion 120 formed on the end face near the pen tube component 200, and the sampling component 110 is sleeved on the insertion protrusion 120.
[0058] Specifically, the insertion protrusion 120 can be configured as a cylindrical structure with an equal outer diameter, or as a two-section cylindrical structure, including a first protrusion section and a second protrusion section. The first protrusion section and the second protrusion section are connected to each other. The first protrusion section is located between the second protrusion section and the pen body component 100. The outer diameter of the first protrusion section is larger than the outer diameter of the second protrusion section. The sampling component 110 is fitted onto the second protrusion section.
[0059] In an alternative embodiment, the end of the insertion protrusion 120 away from the pen body component 100 has a conical surface 121 for piercing the sealing film 311.
[0060] In an optional embodiment, the insertion protrusion 120 is provided with a slot 122 for placing the detection component 400; the sampling component 110 blocks the opening of the slot 122, that is, the sampling component 110 is sleeved on the insertion protrusion 120.
[0061] In addition, when the insertion protrusion 120 is configured as a two-section structure, the slot 122 is located on the second protrusion section to ensure that the sampling component 110 and the detection component 400 are positioned correspondingly.
[0062] In an optional embodiment, the pen body component 100 is provided with a connecting hole 130 on the end face near the pen tube component 200. The connecting hole 130 is used to connect the pen body component 100 and the pen tube component 200 so that the liquid in the pen tube component 200 can enter the pen body component 100 through the connecting hole 130.
[0063] Specifically, the number of connecting holes 130 can be set to multiple. After the sampling component 110 extends into the pen holder component 300, the sampling component 110 is in full contact with the buffer solution. The liquid after the sample and the buffer solution are mixed passes through the pen tube component 200 and enters the pen body component 100 through the connecting holes 130.
[0064] It should be noted that since the test component is located inside the pen body component 100, the pen body component 100 is made of transparent material to facilitate observation of the test results of the test component, and the reading of the test component can be observed through the transparent pen body component 100.
[0065] Regarding the structure and shape of the pen holder component 300, specifically:
[0066] like Figure 4 As shown, the pen holder component 300 is a one-piece molded structure, including a grip portion 310 and a liquid holding portion 320; the grip portion 310 and the liquid holding portion 320 are connected to each other, the grip portion 310 is used for the user to hold, so that the user can install the pen holder component 300 on the pen tube component 200, and the liquid holding portion 320 has a receiving groove with an opening facing the pen tube component 200, the receiving groove is used to hold buffer solution; the sealing film 311 is used to seal the opening of the receiving groove.
[0067] It should be noted that in order to ensure that the buffer solution in the container can overflow, it is necessary to ensure that after the sampling component 110 is inserted into the container, the buffer solution can be squeezed out into the pen body component 100.
[0068] like Figure 5 As shown, in an optional embodiment, the outer wall of the liquid holding part 320 is provided with an outer snap-fit protrusion 321, which can be provided along the entire length of the outer wall surface of the liquid holding part 320, and the inner wall of the pen tube component 200 is provided with an inner snap-fit protrusion 210; the outer snap-fit protrusion 321 is configured to snap into the inner snap-fit protrusion 210, thereby snapping the pen holder component 300 onto the pen tube component 200.
[0069] Regarding the structure and shape of the fixing component 500, specifically:
[0070] like Figure 6 As shown, the fixing component 500 is specifically configured as a plate-shaped structure, with multiple protrusions on the plate-shaped surface, and a slot 510 is formed between two adjacent protrusions.
[0071] In addition, in order to fix the test component in the slot 510, a fixing nail 511 is provided on the inner wall of the slot 510. The fixing nail 511 abuts against or inserts into the test component, thereby fixing the test component in the slot 510 by means of the fixing nail 511.
[0072] In addition, in order to accommodate the plate-shaped fixing component 500, the pen body component 100 is designed as a cuboid structure.
[0073] In alternative implementations, such as Figure 7 As shown, the sampling reaction detection pen also includes a pen cap 600; the pen cap 600 is disposed on the end of the pen body component 100 away from the pen tube component 200. Specifically, the end of the pen body component 100 away from the pen tube component 200 has an opening, and the pen cap 600 is disposed on the end of the pen body component 100 away from the pen tube component 200, thereby sealing the pen body component 100 with the pen cap 600.
[0074] In an optional embodiment, the pen cap 600 is provided with a vent 610, which is used to connect the interior of the pen body component 100 with the outside world, ensuring that the pen body component 100 can communicate with the outside world, thereby increasing the sinking force of the buffer solution movement, and ensuring that the buffer solution located in the pen holder component 300 can smoothly pass through the pen tube component 200 and enter the pen body component 100.
[0075] The sampling reaction detection pen provided by this utility model has the following advantages:
[0076] 1. The detection component 400 is used to determine in real time whether the amount of saliva sample meets the detection requirements.
[0077] 2. After the pen body component 100 is inserted into the pen tube component 200, the sampling component 110 pierces the sealing film 311 and extends into the pen holder component 300, making full contact with the buffer solution. At the same time, the buffer solution holding space is squeezed by the sampling component 110, causing the liquid after the sample and buffer solution are fully mixed to enter the pen body component 100 and come into contact with the test component.
[0078] 3. By setting multiple slots 510 on the fixed component 500, each slot 510 can fix a test component, which significantly improves the detection efficiency and allows for the detection of multiple targets in one sampling.
[0079] 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.
