[0043] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0044] The sample detection pen provided by the embodiment of the present invention includes a sampling test structure 400 and a connecting part 100; the connecting part 100 includes an absorption element 110, a connecting part 120 and a sample volume indicating element 130; an elastic structure is provided at one end of the connecting part 120, and the elastic structure is clamped with the inner side wall of the sampling test structure 400, and the absorption element 110 is sleeved on the outer wall of the connecting part 120; the side wall of the connecting part 120 is provided with at least one mounting groove 121, and a sample volume indicating element 130 is installed in at least one mounting groove 121, and the sample volume indicating element 130 is abutted against the absorption element 110.

[0045] Specifically, the absorption element 110 is used to collect the test sample and can be made of absorbent cotton; and, see Figure 1 and Figure 2The inner wall cross-section of the absorption element 110 is circular. Correspondingly, the cross-section at the corresponding position of the connecting member 120 and the absorption element 110 is set to be circular. The inner wall of the absorption element 110 fits with the outer wall of the connecting member 120, ensuring the installation stability of the absorption element 110; the sample volume indicating element 130 is installed in the installation groove 121, and the outer wall of the sample volume indicating element 130 abuts against the inner wall of the absorption element 110.

[0046] The absorption element 110 is used to absorb the test sample. The sample quantity indicator 130 is in contact with the absorption element 110. When the absorption element 110 absorbs a sufficient amount of the test sample, the sample quantity indicator 130 changes color after absorbing the test sample, providing the user with information that the absorption element 110 is saturated, so that the absorption element 110 can absorb a sufficient amount of the test sample before testing, thereby avoiding the problem of inaccurate test results due to insufficient test sample. An elastic structure is provided at one end of the connector 120. The elastic structure is elastic and can be compressed toward the outer wall of the connector 120 under the drive of an external force, and return to its original shape after the external force is removed. When the absorption element 110 is installed, the elastic structure can be driven to compress so that the absorption element 110 can pass through the elastic structure and be placed on the connector 120. The elastic structure can also be snapped into the inner wall of the sampling test structure 400.

[0047] The following is a detailed description of the structure and shape of the sample detection pen:

[0048] In an optional solution of the embodiment of the present invention, multiple mounting grooves 121 are provided, and the multiple mounting grooves 121 are arranged at intervals along the circumference of the connecting member 120, wherein a sample volume indicator element 130 is installed in one of the mounting grooves 121, and prediction indicator elements are installed in other mounting grooves 121.

[0049] Specifically, the number of mounting grooves 121 can be set according to needs, and can be two, three or four, etc.; the prediction indicator element includes but is not limited to an indicator element for testing the pH value and an indicator element for testing whether it contains alcohol. The prediction indicator element can be set according to needs, and can be provided with two mounting grooves 121, one of the mounting grooves 121 having a sample volume indicator element 130 installed therein, and the other mounting groove 121 having a replaceable prediction indicator element installed therein. The user can install the corresponding prediction indicator element according to the pre-detected items.

[0050] There are multiple mounting grooves 121, which provide multiple mounting positions to realize the pre-detection function of the sample detection pen.

[0051] In an optional solution of the embodiment of the present invention, the length direction of the installation groove 121 is arranged along the axial direction of the connecting member 120.

[0052] Specifically, the sample volume indicating element 130 is usually configured as a cylinder, and the length direction of the mounting groove 121 is configured along the axial direction of the connecting member 120, that is, the length direction of the mounting groove 121 extends along a straight line, so that the shape of the mounting groove 121 matches the shape of the sample volume indicating element 130, thereby allowing the sample volume indicating element 130 to be stably installed in the mounting groove 121.

[0053] In an optional solution of an embodiment of the present invention, the mounting groove 121 in which the sample volume indicating element 130 is mounted extends along the axial direction of the connecting member 120 to the interior of the absorption element 110; the two ends of the sample volume indicating element 130 respectively abut against the two ends of the mounting groove 121, and one end of the sample volume indicating element 130 extends into the absorption element 110 and abuts against the inner wall of the absorption element 110.

[0054] Specifically, see Figure 1 and Figure 2 The bottom of the sample amount indicating element 130 is located between the mounting groove 121 and the absorption element 110 , and the outer wall of the bottom of the sample amount indicating element 130 is in contact with the inner wall of the absorption element 110 .

[0055] The sample amount indicating element 130 abuts against the inner wall of the absorption element 110, so that the sample amount indicating element 130 can absorb the test sample and change color after the absorption element 110 is saturated; it prevents the sample amount indicating element 130 from directly contacting the test sample, or the sample amount indicating element 130 can contact the test sample and change color after only the outer wall of the absorption element 110 contacts the test sample, thereby avoiding the problem of incorrect indication information of the sample amount indicating element 130.

[0056] In the optional solution of the embodiment of the present utility model, see Figures 1 to 3 The side wall of the connecting member 120 is provided with a guide groove 122, and the guide groove 122 and the installation groove 121 are arranged at intervals along the circumference of the connecting member 120; at least one rib 123 is installed in the guide groove 122, and the rib 123 is connected to the side wall of the guide groove 122.

[0057] Specifically, the flow guide groove 122 extends axially along the connector 120 and is used for flow guidance. In this embodiment, two ribs 123 are provided, spaced apart along the extension direction of the flow guide groove 122. Furthermore, an indicator element, including but not limited to a sample volume indicator element 130, may be installed between adjacent ribs 123.

[0058] The guide groove 122 is used to guide the liquid formed by mixing the test sample and the buffer solution on the absorption element 110 to contact the test paper 300. Specifically, when the absorption element 110 is not squeezed by an external force, the test sample will not precipitate and flow into the guide groove 122. When the absorption element 110 is inserted into the buffer mechanism 200, the absorption element 110 is squeezed, the test sample and the buffer solution are mixed, and the mixed liquid flows into the guide groove 122. The ribs 123 are used to increase the strength of the connector 120. At the same time, when the test pen is inserted into the buffer base 220 and pressed down, it can block the liquid from rushing upward rapidly, slowing the liquid flow rate, and preventing the liquid from reaching the test paper 300 too quickly.

[0059] In an optional solution of an embodiment of the present invention, the elastic structure is set as a buckle 124, the top of the buckle 124 is connected to the outer wall of the connecting member 120, and from the top of the buckle 124 to the bottom of the buckle 124, the buckle 124 is inclined in a direction gradually away from the axis of the connecting member 120.

[0060] Specifically, the buckle 124 is tilted to form an elastic region between the buckle 124 and the connector 120, so that the distal end of the buckle 124 can be compressed toward the axis of the connector 120. Of course, an elastic structure configured as an elastic member connected to the outer wall of the connector 120 and exerting an elastic force along the radial direction of the connector 120, such as a spring, is also within the scope of protection of the present invention.

[0061] The buckle 124 enables the connector 120 to be snapped into the inner wall of the sampling and testing structure 400 .

[0062] In an optional solution of the embodiment of the present invention, an avoidance groove 125 is provided at a position corresponding to the connecting member 120 and the buckle 124 .

[0063] Specifically, the depth of the avoidance groove 125 gradually decreases from the top end of the buckle 124 to the bottom end of the latch.

[0064] The avoidance groove 125 increases the space of the elastic area, thereby increasing the movable range of the end of the buckle 124 .

[0065] In an optional solution of the embodiment of the present invention, a step 412 is provided on the inner wall of one end of the sampling and testing structure 400 close to the connecting portion 100 , and the bottom end of the elastic structure abuts against the step 412 .

[0066] Specifically, the sampling test structure 400 includes an inner tube 410 having a cavity 411; the inner wall of the cavity 411 protrudes inward to form a step 412; when the connector 120 is installed, the buckle 124 is first squeezed by the step 412 toward the axis of the connector 120; after passing the step 412, the buckle 124 returns to its original shape, and the bottom surface of the buckle 124 abuts the upper surface of the step 412, completing the connection between the connector 120 and the inner tube 410. For further information, see Figure 5 The outer wall of the bottom of the inner tube 410 is provided with a mounting groove 413, within which a second sealing member 440 is mounted. The second sealing member 440 is used to seal the gap between the inner tube 410 and the buffer mechanism 200. Preferably, the second sealing member 440 is configured as a sealing ring. Furthermore, the inner tube 410 is made of a transparent material, allowing the detection results within the cavity 411 to be observed through the inner tube 410.

[0067] The connecting member 120 is inserted into the cavity 411 , and the bottom end of the buckle 124 abuts against the upper surface of the step 412 , thereby improving the connection strength between the connecting member 120 and the cavity 411 .

[0068] In an optional scheme of an embodiment of the present invention, the connecting member 120 includes a connecting rod 126, a guide portion 127 and a limiting portion 128; the guide portion 127 is installed at one end of the connecting rod 126, and the cross-sectional area of ​​the guide portion 127 gradually increases from the end away from the connecting rod 126 to the end close to the connecting rod 126, and the elastic structure is installed at the end of the connecting rod 126 close to the guide portion 127; the cross-sectional area of ​​the end of the limiting portion 128 that is in contact with the connecting rod 126 is greater than the cross-sectional area of ​​the connecting rod 126, and the cross-sectional area of ​​the limiting portion 128 gradually decreases from the end close to the connecting rod 126 to the end away from the connecting rod 126, and the absorption element 110 is sleeved on the connecting rod 126 and abuts against the limiting portion 128.

[0069] Specifically, see Figure 3 The connecting rod 126 is provided with an avoidance groove 125 at the position corresponding to the buckle 124, and the connecting rod 126 is provided with a plurality of liquid storage grooves 129 at the position corresponding to the absorption element 110. The plurality of liquid storage grooves 129 are arranged at intervals along the circumference and axial direction of the connecting rod 126; the liquid storage grooves 129 can store the saliva absorbed by the absorption element 110, thereby reducing the amount of saliva brought out when the sampling head is taken out of the mouth, and at the same time increasing the absorption capacity of the absorption element 110. Figure 6 For example, the outer diameter of the guide portion 127 gradually increases from top to bottom, which makes it convenient to insert the connector 120 into the inner tube 410 and to install the absorption element 110; the outer diameter of the limiting portion 128 gradually decreases from top to bottom, which makes it convenient to limit the absorption element 110, so that the lower surface of the absorption element 110 overlaps the upper surface of the limiting portion 128, and makes it convenient to insert the connector 120 into the buffer mechanism 200.

[0070] The guide portion 127 guides the installation of the connecting rod 126 or the absorption element 110 , and the limiting portion 128 limits the absorption element 110 .

[0071] In an optional solution of the embodiment of the present invention, the sampling and testing structure 400 further includes a bracket 420 . The bracket 420 is located in the inner tube 410 and is provided with a slot for fixing the test paper 300 .

[0072] Specifically, a stopper protrusion is provided in the middle of the bracket 420, and a slot is provided within the stopper protrusion, through which the test strip 300 passes. The stopper protrusion is provided in the middle of the bracket 420, i.e., the slot is located in the middle of the bracket 420, so that the bracket 420 can fix the middle portion of the test strip 300 and prevent the test strip 300 from falling off.

[0073] The bracket 420 provides support for the test strip 300 .

[0074] In an optional solution of the embodiment of the present invention, the sampling and testing structure 400 further includes a pen cap 430 , which is connected to the bracket 420 and the inner tube 410 .

[0075] Specifically, see Figures 4 to 6 The top of the bracket 420 is provided with a mounting protrusion, and the bottom end of the pen cap 430 is provided with a mounting hole. The mounting protrusion is inserted into the mounting hole to connect the bracket 420 with the pen cap 430; the outer wall of the pen cap 430 is provided with an external thread, and the inner wall of the top of the inner tube 410 is provided with an internal thread. The external thread and the internal thread are threadedly connected to realize the connection between the pen cap 430 and the inner tube 410.

[0076] The pen cap 430 enables the bracket 420 to be installed in the inner tube 410 and can also play a role in sealing the cavity 411 .

[0077] In an optional solution of the embodiment of the present invention, the sample detection pen further includes a buffer mechanism 200 , which is provided with a buffer chamber 210 for accommodating a buffer solution, and one end of the connector 120 on which the absorption element 110 is installed is inserted into the buffer chamber 210 .

[0078] Specifically, the buffer chamber 210 contains a buffer solution for contacting the test sample. When the sample detection pen is used for saliva detection, the absorption element 110 is placed in the mouth to absorb saliva. When the sample amount indicator element 130 changes color, the saliva sample has met the test requirements. The sampling test structure 400 is inserted into the buffer mechanism 200, wherein the inner tube 410 and the buffer mechanism 200 are sealed by the second sealing member 440; as the sampling test structure 400 is inserted into the buffer mechanism 200, the buffer solution contacts the saliva sample; the pressure is continuously pressed down, and under the action of the air pressure, the liquid level of the buffer solution in the buffer mechanism 200 rises to submerge the end of the test paper 300, and the test begins; after a certain period of time, the test results are observed through the inner tube 410.

[0079] The buffer mechanism 200 is used to carry the buffer solution, enabling the sample detection pen to detect the saliva sample.

[0080] In the optional solution of the embodiment of the present utility model, see Figure 5 and Figure 6 The buffer mechanism 200 includes a buffer base 220, a buffer film 240 and a sleeve 250. A buffer protrusion 230 is provided in the buffer base 220. The buffer protrusion 230 is provided with a buffer chamber 210. The buffer film 240 covers the end face of the buffer chamber 210 away from the buffer base 220. The sleeve 250 is sleeved with the buffer protrusion 230, and a first sealing member 260 is installed between the sleeve 250 and the buffer protrusion 230.

[0081] Specifically, the first sealing member 260 is configured as a sealing ring for sealing between the buffer protrusion 230 and the sleeve 250 to prevent the buffer solution from leaking from between the buffer protrusion 230 and the sleeve 250. The buffer film 240 is used to seal the buffer chamber 210 so that the buffer solution can be stored in the buffer chamber 210 for a long time. Furthermore, the sleeve 250 is connected to the buffer protrusion 230 by a thread; of course, other connection methods between the two, such as snap-on connection, etc., should also be within the scope of protection of the embodiment of the present utility model. Preferably, the outer diameter of the bottom end of the sleeve 250 is the same as the outer diameter of the buffer base 220, so that the bottom of the sample detection pen is more stable.

[0082] The buffer base 220 is provided with a buffer protrusion 230 for carrying the buffer solution, and the buffer base 220 serves as the base of the entire sample detection pen, facilitating the placement of the sample detection pen.

[0083] The following is a detailed description of how to use the sample test pen:

[0084] During use, the absorbent element 110 is placed in the mouth to absorb saliva. When saturated with saliva, the sample volume indicator element 130 changes color, indicating that the saliva sample has met the test requirements. The connector 120 is inserted into the buffer mechanism 200. As the sampling test structure 400 is inserted into the buffer mechanism 200, the buffer film 240 is punctured, and the absorbent element 110 enters the buffer chamber 210. The buffer solution mixes with the saliva sample on the absorbent element 110. Continue pressing down. Under the action of air pressure, the mixed liquid rises through the guide groove 122 to submerge the end of the test paper 300, and the test begins. After a certain period of time, the test results are observed through the transparent inner tube 410.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
