If there is a description of "first" or "second", it is only used to distinguish the technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] In the description of the utility model, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0030] In the related art, a detection carrier is usually provided in the detection pen, and a special reagent for detection is provided on the detection carrier, and the corresponding items can be detected by the special reagent. The existing detection pen is generally provided with a detection carrier, and the corresponding items are detected by the detection carrier. However, many users have the need to detect multiple items at the same time, and users can only purchase multiple corresponding detection pens, and use multiple detection pens to detect the corresponding items respectively to meet the above needs. For example, if the user needs to perform a pregnancy test and a urine protein test, the user needs to purchase two detection pens, a pregnancy test pen and a urine protein test pen, and complete the detection operations of the two detection pens to obtain the test results of the pregnancy test and the urine protein test. In this way, the user not only needs to purchase multiple detection products, but also needs to repeat the operation, and the user experience is relatively poor.

[0031] See also Figure 1 and Figure 2 , Figure 1is a schematic diagram of the three-dimensional structure of the detection pen 100 provided in an embodiment of the utility model, Figure 2 yes Figure 1 A schematic diagram of the structure of the detection pen 100 in the exploded state. The embodiment of the utility model provides a detection pen 100, which can be applied to various tests such as pregnancy test, vaginitis test, urethritis test, urine protein test, etc. The detection pen 100 includes a shell 10, a water absorbent member 20 and a plurality of detection carriers 30, and the plurality of detection carriers 30 are arranged in the shell 10. Part of the water absorbent member 20 is arranged in the shell 10 and connected to the plurality of detection carriers 30, and part of the water absorbent member 20 extends out of the shell 10.

[0032] Specifically, the shell 10 is provided with an opening 1001, one end of the water-absorbing member 20 is connected to a plurality of detection carriers 30, and the other end extends out of the shell 10 through the opening 1001. The detection pen 100 also includes a cap 40, which is detachably connected to the shell 10. When the detection pen 100 is not in use, the cap 40 can isolate the water-absorbing member 20 from the outside world to prevent the water-absorbing member 20 from being contaminated by the outside world and affecting the detection results. When the detection pen 100 needs to be used, the cap 40 can be disassembled by the user to expose the water-absorbing member 20. The water-absorbing member 20 can be selected from materials with good water absorption properties such as absorbent sponge, fluff pulp, absorbent paper, sponge, etc. The detection carrier 30 can be selected from a detection test paper added with a detection reagent. Multiple detection carriers 30 correspond to multiple detection items, and the multiple detection items include but are not limited to pregnancy test, urethritis test, vaginitis test, and urine protein test. Optionally, different detection carriers 30 correspond to different detection items. For example, there are three detection carriers 30, which are used for pregnancy test, urethritis test, and urine protein test. The part of the absorbent 20 extending from the shell 10 is used to contact the sample to be tested (such as urine), and absorb the sample to be tested to transfer it to each detection carrier 30, and each detection carrier 30 completes the detection of its own item through the sample to be tested.

[0033] By setting up multiple detection carriers 30, all of which are connected to the water absorbent member 20, the water absorbent member 20 can absorb the sample to be detected and transfer it to the multiple detection carriers 30. The multiple detection carriers 30 complete the detection of multiple items through the sample to be detected. The user does not need to purchase multiple detection products, and the user does not need to repeat operations, which improves the user experience.

[0034] In one embodiment of this implementation, please refer to Figures 2 to 4 , Figure 3 yes Figure 2 A schematic diagram of the three-dimensional structure of the first housing 11 of the detection pen 100, Figure 4 yes Figure 2Schematic diagram of the three-dimensional structure of the second shell 12 of the detection pen 100. The shell 10 includes a first shell 11 and a second shell 12. The first shell 11 and the second shell 12 enclose a cavity 101. A plurality of detection carriers 30 are arranged in the cavity 101, and the first shell 11 and the second shell 12 clamp and fix the plurality of detection carriers 30. Specifically, the first shell 11 is provided with a first matching structure 115, and the second shell 12 is provided with a second matching structure 125, and the first matching structure 115 and the first matching structure 115 cooperate to achieve relative fixation of the first shell 11 and the second shell 12. In this embodiment, the first matching structure 115 is a mounting groove, and the first matching structure 115 is a mounting protrusion. The mounting protrusion and the mounting groove are interference fit, so that the first shell 11 and the second shell 12 are relatively fixed. In other embodiments, the first matching structure 115 and the second matching structure 125 can also be fixed by means of snap connection, threaded connection, etc. The utility model does not limit the fixing method of the first shell 11 and the second shell 12. In this embodiment, the detection carrier 30 is a long strip-shaped sheet structure, and multiple detection carriers 30 are arranged side by side in the cavity 101 along the width direction thereof, and the two sides in the thickness direction of each detection carrier 30 are respectively abutted against the first shell 11 and the second shell 12. The first shell 11 and the second shell 12 are both strip-shaped, and the length direction of the detection carrier 30 is parallel to the length direction of the first shell 11 and the length direction of the second shell 12. In this embodiment, the number of detection carriers 30 is 3, and in other embodiments, the number of detection carriers 30 can also be 2 or more than 3. An observation window 102 is provided on the second shell 12, and the observation window 102 is arranged opposite to the multiple detection carriers 30, and the detection results of the detection carrier 30 can be observed by the user through the observation window 102. By setting the first shell 11 and the second shell 12 to clamp and fix multiple detection carriers 30, the installation and fixing method of the detection carrier 30 is simple, which reduces the difficulty of assembly, and at the same time, there is no need to set an additional fixing structure, which reduces the production cost of the detection pen 100.

[0035] In one embodiment of this implementation, please refer to Figure 2 and Figure 3, the first shell 11 is provided with a first reinforcing rib 111. The extension direction of the first reinforcing rib 111 is parallel to the extension direction of the detection carrier 30, and the first reinforcing rib 111 has a first surface 1111 facing the second shell 12, and the detection carrier 30 abuts against the first surface 1111. Specifically, the extension direction of the detection carrier 30 is the length direction of the detection carrier 30. There are multiple first reinforcing ribs 111, and multiple first reinforcing ribs 111 and multiple detection carriers 30 are arranged in a one-to-one correspondence. In this embodiment, the first shell 11 and the first reinforcing rib 111 are an integrated structure. In other embodiments, the first reinforcing rib 111 can also be fixed to the first shell 11 by some fixing structures. It can be understood that by providing the first reinforcing rib 111, the first reinforcing rib 111 can improve the structural strength of the first shell 11. At the same time, the extension direction of the first reinforcing rib 111 is parallel to the extension direction of the detection carrier 30, and the first surface 1111 of the first reinforcing rib 111 can be well attached and abutted with the detection carrier 30, which is conducive to improving the stability of the installation of the detection carrier 30.

[0036] In one embodiment of this implementation, please continue to refer to Figure 2 and Figure 3 , the first shell 11 is also provided with a second reinforcing rib 112. The second reinforcing rib 112 intersects with the first reinforcing rib 111 and forms an angle, and the second reinforcing rib 112 is provided with a groove 1120 at the position where it intersects with the first reinforcing rib 111. The first bottom wall 1121 of the groove 1120 is connected and flush with the first surface 1111, and a portion of the detection carrier 30 is accommodated in the groove 1120 and abuts against the first bottom wall 1121. Specifically, the second reinforcing rib 112 has a higher height than the first reinforcing rib 111, and the top surface of the second reinforcing rib 112 is provided with a groove 1120, and the depth of the groove 1120 is equal to the height difference between the second reinforcing rib 112 and the first reinforcing rib 111, so that the first bottom wall 1121 of the groove 1120 and the top surface of the first reinforcing rib 111 (i.e., the first surface 1111) are flush and connected. It can be understood that the second reinforcement rib 112 can improve the structural strength of the first shell 11. At the same time, the second reinforcement rib 112 can provide a groove 1120, and part of the detection carrier 30 is located in the groove 1120. The groove 1120 limits the detection carrier 30 in the width direction to facilitate the positioning and installation of the detection carrier 30.

[0037] In this embodiment, the angle formed by the intersection of the second reinforcing rib 112 and the first reinforcing rib 111 is 90°. In other embodiments, the angle formed by the intersection of the second reinforcing rib 112 and the first reinforcing rib 111 may also be other degrees, such as 75°, 60°, etc. The utility model does not specifically limit the angle formed by the intersection of the second reinforcing rib 112 and the first reinforcing rib 111.

[0038] In this embodiment, the second reinforcing rib 112, the first reinforcing rib 111 and the first shell 11 are an integrated structure, and are all made of plastic material, and can be made by injection molding, which is simple in process and low in cost. In other embodiments, the second reinforcing rib 112, the first reinforcing rib 111 and the first shell 11 can also be a split structure.

[0039] In one embodiment of this implementation, please continue to refer to Figure 2 and Figure 3 , the number of the first reinforcing ribs 111 is multiple, and the multiple first reinforcing ribs 111 are arranged corresponding to the multiple detection carriers 30. The multiple first reinforcing ribs 111 all intersect with the second reinforcing ribs 112, and the second reinforcing ribs 112 are provided with grooves 1120 at the positions where they intersect with each first reinforcing rib 111. The multiple detection carriers 30 are respectively accommodated in the corresponding grooves 1120. In this embodiment, the number of the first reinforcing ribs 111 and the detection carrier 30 are both 3, the second reinforcing ribs 112 intersect with the three first reinforcing ribs 111 respectively, and the three intersection positions are provided with grooves 1120. The second reinforcing ribs 112 can provide grooves 1120 for positioning of the multiple detection carriers 30, and the overall structure is relatively simple, which is conducive to reducing costs.

[0040] In one embodiment of this implementation, please continue to refer to Figure 2 and Figure 3 , the first reinforcing rib 111 has a transition surface 1112 facing the second shell 12. One side of the transition surface 1112 is connected to the first surface 1111, and the other side is connected to the first inner wall 1101 of the first shell 11. The transition surface 1112 is inclined relative to the first surface 1111 and the first inner wall 1101, and the detection carrier 30 abuts against the first surface 1111, the transition surface 1112 and the first inner wall 1101 in sequence. Specifically, the transition surface 1112 is a plane. It can be understood that the detection carrier 30 needs to be connected to the water absorbing member 20 at the position of the first inner wall 1101, so the detection carrier 30 needs to extend to the first inner wall 1101 while being installed on the first reinforcing rib 111. There is a height difference between the first surface 1111 and the first inner wall 1101. By setting a transition surface 1112, the transition surface 1112 is inclined relative to the first surface 1111 and the first inner wall 1101. The detection carrier 30 is in contact with the first surface 1111, the transition surface 1112 and the first inner wall 1101 in turn. The detection carrier 30 can be installed on the first reinforcement rib 111 and extend to the first inner wall 1101, so as to facilitate the connection between the detection carrier 30 and the water absorbent member 20.

[0041] In this embodiment, one end of the detection carrier 30 extends to the first inner wall 1101, and the opposite sides of the end are respectively in contact with the first inner wall 1101 and the water absorbing member 20, and the side of the water absorbing member 20 facing away from the detection carrier 30 is in contact with the second shell 12. The water absorbing member 20 and the detection carrier 30 are clamped and fixed by the first shell 11 and the second shell 12.

[0042] In one embodiment of this implementation, please continue to refer to Figure 2 and Figure 3 , the first reinforcing rib 111 is provided with a limit block 1125, and the limit block 1125 is used to limit the detection carrier 30 from being away from the water absorbent 20 along the extension direction of the first reinforcing rib 111. Specifically, the limit block 1125 is arranged on the first surface 1111, and the limit block 1125 is raised relative to the first surface 1111. One end of the detection carrier 30 away from the water absorbent 20 is connected to or spaced opposite to the limit block 1125. It can be understood that when the detection carrier 30 is installed on the first reinforcing rib 111, it is necessary to ensure that the length of the detection carrier 30 reserved on the first inner wall 1101 is sufficient so that the detection carrier 30 can fully contact with the water absorbent 20 to receive the sample to be detected transferred by the water absorbent 20. By setting the limit block 1125, the limit block 1125 limits the detection carrier 30 from being away from the water absorbent 20 along the extension direction of the first reinforcing rib 111, and the detection carrier 30 can fully contact with the water absorbent 20 to facilitate the transfer of the sample to be detected.

[0043] In one embodiment of this implementation, please refer to Figures 2 to 4 , a first mounting block 113 is provided on the first inner wall 1101 of the first shell 11, and a second mounting block 122 is provided on the second inner wall 1201 of the second shell 12. The extension direction of the first mounting block 113 and the extension direction of the second mounting block 122 intersect, and the water absorbent 20 is clamped and fixed between the first mounting block 113 and the second mounting block 122. Specifically, the extension direction of the first mounting block 113 is the same as the extension direction of the first reinforcing rib 111, the extension direction of the second mounting block 122 is the same as the extension direction of the second reinforcing rib 112, and the extension direction of the first mounting block 113 is perpendicular to the extension direction of the second mounting block 122. The orthographic projections of the first mounting block 113 and the second mounting block 122 on the plane where the water absorbent 20 is located at least partially overlap. It can be understood that by clamping and fixing the water absorbent 20 by the first mounting block 113 and the second mounting block 122, the installation and fixing method of the water absorbent 20 is relatively simple and the cost is relatively low. At the same time, the extension direction of the first mounting block 113 and the extension direction of the second mounting block 122 intersect, and the first mounting block 113 and the second mounting block 122 are in more complete contact with the water absorbent member 20 , so that the first mounting block 113 and the second mounting block 122 can better clamp the water absorbent member 20 .

[0044] In one embodiment of this implementation, please continue to refer to Figures 2 to 4 , the surface of the first mounting block 113 facing away from the first inner wall 1101 and / or the surface of the second mounting block 122 facing away from the second inner wall 1201 are provided with mounting columns. The mounting columns are connected to the water absorbent 20. In this embodiment, the surface of the first mounting block 113 facing away from the first inner wall 1101 and the surface of the second mounting block 122 facing away from the second inner wall 1201 are both provided with mounting columns. For the convenience of description, the mounting columns on the surface of the first mounting block 113 facing away from the first inner wall 1101 are defined as first mounting columns 1131, and the mounting columns on the surface of the second mounting block 122 facing away from the second inner wall 1201 are defined as second mounting columns 1221. In other embodiments, the mounting columns may be provided on one of the first mounting block 113 and the second mounting block 122. By providing mounting columns on the surface of the first mounting block 113 facing away from the first inner wall 1101 and / or the surface of the second mounting block 122 facing away from the second inner wall 1201, it is beneficial for the first mounting block 113 and the second mounting block 122 to fully contact with the water absorbent 20.

[0045] It can be understood that under the clamping of the first mounting block 113 and the second mounting block 122, the water absorbent member 20 can well press and fix the water absorbent end of the detection carrier 30, and can prevent the sample to be tested (such as urine) from rushing to the water absorbent end of the detection carrier 30 all at once, resulting in the inability to perform subsequent chromatography.

[0046] In this embodiment, the absorbent member 20 is a deformable absorbent cotton, and the first mounting block 113 and the second mounting block 122 respectively squeeze the opposite sides of the absorbent cotton, so that the absorbent cotton is deformed and relatively fixed. There are multiple first mounting columns 1131, and multiple first mounting columns 1131 are arranged in an array on the surface of the first mounting block 113 facing away from the first inner wall 1101, and the arrangement direction of the multiple first mounting columns 1131 is the same as the extension direction of the first mounting block 113. The end of the first mounting column 1131 is a pointed tip, so that the first mounting column 1131 is embedded in the absorbent cotton, so that the absorbent cotton is relatively fixed. Similarly, there are multiple second mounting columns 1221, and multiple second mounting columns 1221 are arranged in an array on the surface of the second mounting block 122 facing away from the second inner wall 1201, and the arrangement direction of the multiple second mounting columns 1221 is the same as the extension direction of the second mounting block 122. The end of the second mounting column 1221 is a pointed tip, so that the second mounting column 1221 is embedded in the absorbent cotton. By providing a plurality of first mounting posts 1131 with pointed ends and a plurality of second mounting posts 1221 with pointed ends, the absorbent cotton can be better fixed in place in cooperation with the deformable absorbent cotton.

[0047] In this embodiment, the number of the first mounting blocks 113 and the second mounting blocks 122 are both two, the two first mounting blocks 113 are arranged at intervals, and the two second mounting blocks 122 are arranged at intervals, and the orthographic projections of the two first mounting blocks 113 and the two second mounting blocks 122 on the plane where the water absorbent 20 is located are in the shape of a "#". Such an arrangement can better clamp and fix the water absorbent 20. Further, a top block 123 is also provided on the second inner wall 1201, and the top block 123 is located between the two second mounting blocks 122. The end of the top block 123 is a pointed end, and the top block 123 abuts against the water absorbent 20. The top block 123 can cooperate with the first mounting block 113 and the second mounting block 122 to better fix the water absorbent 20.

[0048] In this embodiment, the first housing 11 is provided with a stopper 114, and the stopper 114 is provided on the first inner wall 1101. One end of the first mounting block 113 is connected to the edge of the first housing 11 at the opening 1001, and the other end is connected to the stopper 114. The stopper 114 is used to limit the movement of the water absorbent 20 in a direction away from the opening 1001, so that the water absorbent 20 can have a sufficient length to extend out of the opening 1001, so that the water absorbent 20 can absorb the sample to be tested. Specifically, the number of the stopper 114 is two, and the two stoppers 114 are connected to the two first mounting blocks 113 accordingly.

[0049] In one embodiment of this implementation, please continue to refer to Figures 2 to 4 The second shell 12 is provided with a third reinforcing rib 121, and the third reinforcing rib 121 abuts against the side of the detection carrier 30 facing away from the first reinforcing rib 111. On the plane where the detection carrier 30 is located, the orthographic projection of the third reinforcing rib 121 and the orthographic projection of the first reinforcing rib 111 at least partially overlap. By providing the third reinforcing rib 121, the third reinforcing rib 121 and the first reinforcing rib 111 clamp and fix the detection carrier 30, and the installation method of the detection carrier 30 is relatively simple and the installation is relatively stable. Moreover, the third reinforcing rib 121 can also play a role in strengthening the structure of the second shell 12.

[0050] In this embodiment, the extension direction of the third reinforcing rib 121 is the same as the extension direction of the first reinforcing rib 111, so as to better clamp the detection carrier 30.
