Abstract
Description
Technical Field
[0001] This invention relates to the field of medical testing technology, specifically a reagent kit. Background Technology
[0002] Respiratory and pulmonary diseases are among the most common infectious diseases. Common symptoms include fever, fatigue, dry cough, and gradually developing difficulty breathing. Some patients have mild symptoms, and some are even asymptomatic. To meet the rapid detection requirements in the biomedical testing field, test strips and kits prepared using the colloidal gold method have been widely used.
[0003] During testing, a sampling swab needs to be inserted into the oral cavity and throat to collect a sample. Then, the tip of the sampling swab is inserted into the sample extraction solution and stirred to mix the sample collected by the swab tip into the sample extraction solution. The sample extraction solution containing the sample is then dripped into the sample addition well, and the results are observed through the observation window. In actual operation, the amount of sample collected by the swab tip is generally too small and it is not easy to completely mix into the sample extraction solution, which will cause detection deviation. In addition, it is also easy to make mistakes when adding the sample extraction solution, which can easily cause the sample extraction solution to spill, making the operation inconvenient. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a reagent kit that facilitates the full mixing of the sample collected by the sampling swab tip with the sample extraction solution, thereby improving the accuracy of the detection. Furthermore, the operation of adding the sample extraction solution into the sample addition well is convenient, and the sample extraction solution will not spill out. It is easy to use and can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a reagent kit, comprising a reagent kit body and a sample addition well, wherein a test strip is installed inside the reagent kit body, and a lid is installed on the top of the reagent kit body, and a sample addition well is provided on the left side of the lid, further comprising: The sample handling box includes a box body, and the box body is integrally connected to the left end of the main body of the reagent kit; The sample extraction mechanism includes a sample extraction liquid bottle, a sampling swab support assembly, and a top sealing assembly. The sample extraction liquid bottle is fixed in the middle of the box. The top side of the sample extraction liquid bottle is connected to a sample addition control mechanism. The bottom side of the sample extraction liquid bottle is connected to a sample addition hole through a sample addition delivery assembly. The top of the sample extraction liquid bottle is equipped with a sampling swab support assembly, and the top of the sampling swab support assembly is connected to a top sealing assembly. The sample extraction enhancement mechanism is installed on the box body and is connected to the sampling swab support assembly.
[0006] The lid securely holds the test strip within the main body of the reagent kit. During use, first insert the sampling swab into the mouth and throat to collect a sample. Then, using the top sealing assembly, open the top of the sampling swab support assembly. Insert the swab tip downwards into the sampling swab support assembly, simultaneously immersing the tip in the sample extraction solution within the sample extraction solution bottle. Close the top sealing assembly to seal the top of the sampling swab support assembly. The sample extraction enhancement mechanism then rotates the sampling swab support assembly and the sampling swab within it relative to the sample extraction solution bottle, allowing the sample collected by the swab tip to fully pass through the sampling swab support assembly. The sample is mixed into the sample extract solution in the sample extraction solution bottle. This sample extraction enhancement mechanism enables the sample collected from the sampling swab tip to be quickly and efficiently mixed into the sample extract solution. The sample addition control mechanism pumps air to pressurize the top of the sample extract solution bottle, allowing the sample extract solution mixed with the sample at the bottom of the bottle to enter the sample addition hole through the sample addition delivery component. The sample extract solution mixed with the sample in the sample addition hole permeates onto the test strip. The test result can be obtained by observing the test strip. Therefore, the operator does not need to hold the sample extract solution bottle and add the sample extract solution drop by drop, avoiding the spillage of the sample extract solution, making the operation convenient.
[0007] Furthermore, the sampling swab support assembly includes an inner sleeve, an extraction gear, a sealing ring, a sampling swab support tube, and an exchange channel. The bottom of the sampling swab support tube extends into the sample extraction liquid bottle. An exchange channel is formed in a ring array at the bottom of the sampling swab support tube. An extraction gear is fixedly sleeved on the outer periphery of the top of the sampling swab support tube. The bottom of the extraction gear is fixedly connected to the inner sleeve. The inner sleeve is rotatably sleeved on the inner side of the top of the sample extraction liquid bottle. A sealing ring is installed between the inner sleeve and the inner side of the top of the sample extraction liquid bottle. The sealing ring enhances the seal between the inner sleeve and the sample extraction solution bottle, preventing leakage of the sample extraction solution when the kit is inverted. The tip of the sampling swab is inserted into the bottom of the sampling swab support tube. The sample extraction solution contacts the tip of the sampling swab through the exchange channel. Simultaneously, the exchange channel allows the sample collected by the sampling swab tip to mix into the sample extraction solution in the sample extraction solution bottle. The extraction gear connects to the sample extraction enhancement mechanism. The sample extraction enhancement mechanism, with the help of the extraction gear, drives the sampling swab support tube to rotate relative to the sample extraction solution bottle. This rotation of the sampling swab promotes the mixing of the sample from the sampling swab tip into the sample extraction solution, preventing insufficient sample from the sampling swab tip from mixing into the sample extraction solution and thus avoiding affecting the test results.
[0008] Furthermore, the sample extraction mechanism also includes stirring blades, with a ring array of stirring blades arranged on the bottom outer periphery of the sampling swab support tube. When the sampling swab support tube rotates relative to the sample extraction liquid bottle, it also drives the stirring blades to rotate. The stirring blades are used to stir the sample extraction liquid, promoting uniform distribution of the sample in the sample extraction liquid and avoiding detection deviations caused by uneven distribution of the sample in the sample extraction liquid.
[0009] Furthermore, the top sealing assembly includes a bottle cap, a rubber cap, and an insertion hole. The rubber cap is installed inside the top of the bottle cap, and the insertion hole is located at the center of the top of the bottle cap. The inner bottom of the bottle cap is threadedly connected to the outer top of the sampling swab support cylinder. The bottle cap, together with the rubber cap, seals the top of the sampling swab support cylinder. In use, loosening the bottle cap allows the bottle cap and rubber cap to be removed from the top of the sampling swab support cylinder. The sampled swab, with its end facing down, is then inserted into the sampling swab support cylinder. If the sampling swab is short, the bottle cap can be directly closed. Note that the sample extract level should not exceed the hand-held end of the sampling swab. If the sampling swab is long, it can be broken in the middle, and the sample-containing swab can be placed into the sampling swab support cylinder. Alternatively, the tip of the sampling swab can be removed from the hand-held end. The rubber cap is inserted through the middle, allowing the tip of the sampling swab to pass through the insertion hole in the middle of the cap. This method allows the rubber cap to fix the sampling swab in place, and the sampling swab support tube can rotate more effectively, allowing the sample at the tip of the sampling swab to mix better into the sample extract. However, there will be a certain gap between the top of the sampling swab and the rubber cap, which may reduce the effectiveness of the sample addition control mechanism in pumping air to the top of the sample extract bottle. Generally, it is necessary to increase the thickness of the rubber cap to reduce air leakage between the top of the sampling swab and the rubber cap.
[0010] Furthermore, the sample extraction enhancement mechanism includes a pressing block, a rack, a spring end sleeve, and a return spring. Two pressing slots are respectively opened on the front and rear sides of the box. Two pressing blocks are slidably connected longitudinally in the two pressing slots. Two longitudinal racks are fixedly connected to one side of the two pressing blocks in the box. The two racks are respectively meshed with the two sides of the extraction gear. The front and rear sides of the sample extraction liquid bottle are respectively connected to one end of the two longitudinal return springs through two spring end sleeves. The other end of the two return springs is respectively connected to the two corresponding pressing blocks. The operator presses the two pressing blocks into the box, causing the two racks to move closer together. This allows the extraction gear to rotate the sampling swab support tube clockwise relative to the sample extraction bottle. At this time, the two return springs are compressed. Releasing the two pressing blocks causes the two return springs to stretch due to their elasticity, and the two pressing blocks extend out of the two pressing slots. The two racks move away from each other, and the extraction gear drives the sampling swab support tube to rotate counterclockwise relative to the sample extraction bottle. Repeating the above steps allows the sampling swab support tube to rotate back and forth relative to the sample extraction bottle, promoting better mixing of the sample from the sampling swab tip into the sample extraction solution. The exchange slots on the sampling swab support tube allow the sample to be evenly distributed in the sample extraction solution within the sample extraction bottle.
[0011] Furthermore, it also includes a swab head squeezing mechanism, which comprises spokes, a squeezing sleeve, squeezing protrusions, and exchange holes. The bottom of the sampling swab support cylinder is connected to the top of the squeezing sleeve via the spokes. Multiple squeezing protrusions are vertically and equidistantly arranged inside the squeezing sleeve, and multiple exchange holes are provided on the squeezing sleeve. When the sampling swab tip is inserted into the sampling swab support cylinder, it can be directly inserted into the squeezing sleeve. The multiple squeezing protrusions on the inner wall of the squeezing sleeve can squeeze the sampling swab tip multiple times. The sampling swab tip will repeatedly absorb and release the sample extract, thereby better mixing the sample from the sampling swab tip into the sample extract. The squeezing sleeve also rotates with the sampling swab support cylinder, allowing the sample to be more evenly distributed in the sample extract through the exchange holes.
[0012] Furthermore, the sample addition control mechanism includes a second pressing block, a latex inflation ball, a support plate, an inlet one-way valve, an inlet pipe, an outlet one-way valve, and an inflation pipe. A second pressing groove is provided on the left side of the box body, and a second pressing block is slidably connected in the second pressing groove. A support plate is provided on the left side of the box body, and a latex inflation ball is installed on the left side of the support plate. The left side of the latex inflation ball abuts against the right side of the second pressing block. An inlet pipe is provided on the top of the latex inflation ball, and an inlet one-way valve is installed on the inlet pipe. The right side of the latex inflation ball is connected to one end of the inflation pipe through the outlet one-way valve, and the other end of the inflation pipe is connected to the top side of the sample extraction liquid bottle. Press the second pressing block into the box, compressing the latex inflation ball. Air from the latex inflation ball enters the sample extract bottle through the exhaust valve and inflation tube, increasing the pressure inside the sample extract bottle. The sample extract at the bottom of the bottle is then transported to the sample addition hole through the sample addition delivery assembly. Release the second pressing block, and the latex inflation ball draws in air through the intake valve and intake tube to return to its original shape. Repeat this step until the sample extraction hole is full. This completes the addition of the sample extract into the sample addition hole. This method of adding sample extract is convenient and prevents spillage.
[0013] Furthermore, the sample addition and delivery assembly includes a sample delivery tube, a connecting tube, and an addition channel. An addition channel is located inside the left end of the box cover, with its right end communicating with the sample addition hole. The left end of the addition channel extends to the left side of the box cover. A connecting tube is located on the top right side of the box body, with its right end inserted into the left end of the addition channel. The left end of the connecting tube connects to one end of the sample delivery tube, and the other end connects to the bottom side of the sample extraction solution bottle. After air is introduced into the sample extraction solution bottle, the internal pressure increases, and the sample extraction solution at the bottom of the bottle enters the addition channel through the sample delivery tube and the connecting tube, finally entering the sample addition hole and contacting the test end on the left side of the test strip.
[0014] Furthermore, the sample handling box also includes a stepped groove, a cover plate, and a snap-fit frame. The stepped groove is located on the inner top side of the box body, and the snap-fit frame is located on the outer side of the cover plate. The snap-fit frame engages with the stepped groove, and a circular hole corresponding to the bottle cap is formed in the center of the cover plate. The stepped groove and snap-fit frame work together to mount the cover plate on the top of the box body, concealing the internal components and maintaining an aesthetically pleasing appearance. The circular hole facilitates opening the bottle cap.
[0015] Furthermore, the kit also includes a sampling swab placement assembly, which comprises a placement groove, a sinking groove, swab positioning seats, and a locking groove. The placement groove is located on the side of the kit body, and the sinking groove is located at the bottom of the placement groove. Two swab positioning seats are located within the sinking groove, and a locking groove is located on the upper middle part of the placement groove. The sampling swab can be placed into the sinking groove through the placement groove. The swab positioning seats can limit the movement of the sampling swab. When removing the sampling swab, the operator's fingers can remove the sampling swab through the locking groove.
[0016] Compared with existing technologies, the advantages of this kit are: 1. The tip of the sampling swab is inserted into the bottom of the sampling swab support tube. The sample extraction solution comes into contact with the tip of the sampling swab through the exchange channel. At the same time, the sample collected by the tip of the sampling swab can be mixed into the sample extraction solution in the sample extraction solution bottle through the exchange channel. The sample extraction enhancement mechanism can drive the sampling swab support tube to rotate relative to the sample extraction solution bottle by means of extraction gear. This can drive the sampling swab to rotate, which can promote the mixing of the sample from the tip of the sampling swab into the sample extraction solution. This avoids the sample from the tip of the sampling swab being too small to be easily mixed into the sample extraction solution, thus avoiding affecting the test results.
[0017] 2. When the sampling swab tip is inserted into the sampling swab support tube, it can be directly inserted into the squeezing sleeve. The multiple squeezing protrusions on the inner wall of the squeezing sleeve can squeeze the sampling swab tip multiple times. The sampling swab tip will absorb and release the sample extract multiple times, thereby better mixing the sample from the sampling swab tip into the sample extract. The squeezing sleeve will also rotate with the sampling swab support tube, and the sample will be more evenly distributed in the sample extract through the exchange hole.
[0018] 3. Press the second pressing block into the box. The latex inflation ball is squeezed, and the air inside the latex inflation ball enters the sample extract bottle through the air outlet one-way valve and the inflation tube. The pressure inside the sample extract bottle increases, and the sample extract at the bottom of the sample extract bottle is transported to the sample addition hole through the sample addition delivery component. Release the second pressing block, and the latex inflation ball draws in air through the air inlet one-way valve and the air inlet tube to return to its original state. Repeat this step until the sample extraction hole is full. This completes the addition of the sample extraction solution into the sample addition hole. This method of adding sample extraction solution is convenient and less likely to spill.
[0019] 4. It facilitates the thorough mixing of the sample collected from the sampling swab tip with the sample extraction solution, improving the accuracy of the test. Furthermore, the operation of adding the sample extraction solution into the sample addition well is convenient, and the sample extraction solution will not spill out, making it easy to use.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Example 1, please refer to Figures 1 to 11 This embodiment provides a technical solution: a reagent kit, including a reagent kit structure 1, the reagent kit structure 1 including a reagent kit body 11, a test strip 15, a box cover 18 and a sample addition hole 113. The test strip 15 is installed inside the reagent kit body 11, and the box cover 18 is installed on the top of the reagent kit body 11. The box cover 18 stably fixes the test strip 15 inside the reagent kit body 11, and the sample addition hole 113 is opened on the left side of the box cover 18.
[0023] The reagent kit component 1 also includes a test strip limiting component and a lid locking component.
[0024] The test strip limiting assembly includes a test strip side bracket 12, a test strip edge limiting groove 13, a support strip 14, and a pressure strip 111. Two test strip side brackets 12 are respectively provided on the front and back sides of the reagent kit body 11. The tops of the two test strip side brackets 12, which are close to each other, each have a test strip edge limiting groove 13. At least four support strips 14 are arranged equidistantly between the two test strip side brackets 12. The top of the support strip 14 is flush with the bottom of the test strip edge limiting groove 13. The front and back sides of the test strip 15 respectively cooperate with the two test strip edge limiting grooves 13. Two pressure strips 111 are respectively provided on the bottom of the lid 18 corresponding to the positions of the two test strip edge limiting grooves 13. The pressure strip 111 and the edge limiting groove 13 limit the front and rear sides of the test strip 15. The support strip 14 supports the bottom of the test strip 15 to prevent the test strip 15 from sinking downward and affecting the subsequent penetration of the sample extract. At the same time, the support strip 14 is spaced apart to reduce the contact area with the bottom of the test strip 15, which will also reduce the impact on the penetration of the sample extract on the test strip 15. The pressure strip 111, together with the edge limiting groove 13, fixes the front and rear sides of the test strip 15 and also maintains a certain gap between the test strip 15 and the box cover 18, which will also prevent the contact between the box cover 18 and the upper side of the test strip 15 from affecting the penetration process of the sample extract on the test strip 15.
[0025] The reagent kit 1 also includes an observation window 112. An observation window 112 is provided on the upper right side of the lid 18. Through the observation window 112, the control line and the test line on the test strip 15 can be observed. The control line indicates whether the test is effective, and the test line indicates whether the sample contains the target substance.
[0026] The reagent kit 1 also includes a sample limiting rubber ring 114. Due to the presence of the pressure strip 111, a certain gap is maintained between the test strip 15 and the lid 18. When sample extract containing the sample is added to the sample addition hole 113, the sample extract can easily flow on the test strip 15 or even flow to the bottom of the reagent kit body 11. The sample extract cannot effectively penetrate the test strip 15. Therefore, a sample limiting rubber ring 114 is provided around the sample addition hole 113 at the bottom of the lid 18. The bottom of the sample limiting rubber ring 114 contacts the upper side of the test strip 15. After the sample extract is added to the sample addition hole 113, the sample extract will completely penetrate the test strip 15 instead of flowing randomly, thereby ensuring the effectiveness and reliability of the test.
[0027] It also includes a sample handling box 2, a sample extraction mechanism 3, and a sample extraction enhancement mechanism 5.
[0028] The sample handling box 2 includes a box body 21. The left end of the reagent kit body 11 is integrally connected to the box body 21, and the top of the box body 21 is flush with the top of the box cover 18.
[0029] The lid locking assembly includes slots 16, slots 17, insert rods 19, and locking feet 110. Two slots 16 are provided at the front and rear ends of the connection between the reagent kit body 11 and the box body 21. Two insert rods 19 are provided at the left end of the lid 18, and the two insert rods 19 are inserted into the two slots 16 respectively. Two slots 17 are provided at the front and rear sides of the right end of the reagent kit body 11. Two locking feet 110 are provided at the bottom right end of the lid 18, and the two locking feet 110 are engaged with the two slots 17 respectively, thereby achieving a stable connection between the lid 18 and the reagent kit body 11.
[0030] The sample extraction mechanism 3 includes a sample extraction liquid bottle 31, a sampling swab support assembly, and a top sealing assembly. The sample extraction liquid bottle 31 is fixed in the middle of the box body 21. The top side of the sample extraction liquid bottle 31 is connected to the sample addition control mechanism 6. The bottom side of the sample extraction liquid bottle 31 is connected to the sample addition hole 113 through the sample addition delivery assembly 7. The top of the sample extraction liquid bottle 31 is equipped with the sampling swab support assembly, and the top of the sampling swab support assembly is connected to the top sealing assembly.
[0031] The sample extraction solution is pre-filled into the sample extraction solution bottle 31, and the liquid level of the sample extraction solution is located at half the height of the sample extraction solution bottle 31.
[0032] The sampling swab support assembly includes an inner sleeve 32, an extraction gear 33, a sealing ring 34, a sampling swab support cylinder 35, and an exchange channel 36. The bottom of the sampling swab support cylinder 35 extends into the sample extraction liquid bottle 31. The bottom of the sampling swab support cylinder 35 has an annular array of exchange channels 36. The extraction gear 33 is fixedly sleeved on the outer periphery of the top of the sampling swab support cylinder 35. The bottom of the extraction gear 33 is fixedly connected to the inner sleeve 32. The inner sleeve 32 is rotatably sleeved on the inner top of the sample extraction liquid bottle 31. A sealing ring 34 is installed between the inner sleeve 32 and the inner top of the sample extraction liquid bottle 31. The outer side of the inner sleeve 32 has an annular groove 1 that mates with the sealing ring 34, and the inner top of the sample extraction liquid bottle 31 has an annular groove 2 that mates with the sealing ring 34. The sealing ring 34 helps improve the sealing at the connection between the inner sleeve 32 and the sample extraction liquid bottle 31, preventing leakage of the sample extraction liquid when the reagent kit is inverted. The end of the sampling swab is inserted into the bottom of the sampling swab support tube 35, and the sample extraction liquid contacts the end of the sampling swab through the exchange channel 36. At the same time, the sample collected by the end of the sampling swab can be mixed into the sample extraction liquid in the sample extraction liquid bottle 31 through the exchange channel 36. The extraction gear 33 is used to connect the sample extraction enhancement mechanism 5. The sample extraction enhancement mechanism 5 can drive the sampling swab support tube 35 to rotate relative to the sample extraction liquid bottle 31 with the help of the extraction gear 33. This can drive the sampling swab to rotate, promote the mixing of the sample from the end of the sampling swab into the sample extraction liquid, and avoid the sample from the end of the sampling swab being too small to be easily mixed into the sample extraction liquid, thus avoiding affecting the test results.
[0033] The sample extraction mechanism 3 also includes stirring blades 37, which are arranged in a ring array on the bottom outer periphery of the sampling swab support cylinder 35. When the sampling swab support cylinder 35 rotates relative to the sample extraction liquid bottle 31, it also drives the stirring blades 37 to rotate. The stirring blades 37 are used to stir the sample extraction liquid, promote the uniform distribution of the sample in the sample extraction liquid, and avoid the detection deviation caused by uneven distribution of the sample in the sample extraction liquid.
[0034] The top sealing assembly includes a bottle cap 38, a rubber cap 39, and an insertion hole 310. The rubber cap 39 is installed inside the top of the bottle cap 38, and the insertion hole 310 is located at the center of the top of the bottle cap 38. The inner bottom of the bottle cap 38 is threadedly connected to the outer top of the sampling swab support cylinder 35. The bottle cap 38, together with the rubber cap 39, seals the top of the sampling swab support cylinder 35. In use, loosening the bottle cap 38 allows the bottle cap 38 and rubber cap 39 to be removed from the top of the sampling swab support cylinder 35. The sampled swab, with its end facing down, is then inserted into the sampling swab support cylinder 35. If the sampling swab is short, the bottle cap 38 can be directly closed. Note that the sample extract level should not exceed the handheld end of the sampling swab. If the sampling swab is long, it can be broken in the middle, and the sample-containing swab can be placed into the sampling swab support cylinder 35. Alternatively, the tip of the sampling swab can be removed from the hand. The rubber cap 39 passes through the middle, allowing the tip of the sampling swab to pass through the insertion hole 310 in the middle of the bottle cap 38. This method allows the rubber cap 39 to fix the sampling swab in place, and the sampling swab support cylinder 35 can rotate more effectively, allowing the sample at the tip of the sampling swab to mix better into the sample extract. However, there will be a certain gap between the top of the sampling swab and the rubber cap 39, which may reduce the effect of the sample addition control mechanism 6 pumping air to the top of the sample extract bottle 31. Generally, it is necessary to increase the thickness of the rubber cap 39 to reduce air leakage between the top of the sampling swab and the rubber cap 39.
[0035] The sample extraction enhancement mechanism 5 is installed on the box 21 and is connected to the sampling swab support assembly.
[0036] The sample extraction enhancement mechanism 5 includes a pressing block 51, a rack 52, a spring end sleeve 53, and a reset spring 54. Two pressing slots are respectively opened on the front and rear sides of the box body 21. Two pressing blocks 51 are slidably connected in the two pressing slots. Two longitudinal racks 52 are fixedly connected to one side of the two pressing blocks 51 inside the box body 21. The two racks 52 are respectively meshed with the two sides of the extraction gear 33. The front and rear sides of the sample extraction liquid bottle 31 are respectively connected to one end of the two longitudinal reset springs 54 through the two spring end sleeves 53. The other end of the two reset springs 54 are respectively connected to the two corresponding pressing blocks 51. The operator presses the two pressing blocks 51 into the box 21 by hand, causing the two racks 52 to move closer together. The extraction gear 33 drives the sampling swab support cylinder 35 to rotate clockwise relative to the sample extraction liquid bottle 31. At this time, the two return springs 54 are compressed. When the two pressing blocks 51 are released, the two return springs 54 stretch due to elasticity, and the two pressing blocks 51 extend out from the two pressing slots. The two racks 52 move away from each other, and the extraction gear 33 drives the sampling swab support cylinder 35 to rotate counterclockwise relative to the sample extraction liquid bottle 31. By repeating the above steps, the sampling swab support cylinder 35 can rotate back and forth relative to the sample extraction liquid bottle 31, which promotes better mixing of the sample at the end of the sampling swab in the sampling swab support cylinder 35 into the sample extraction liquid. The exchange slot 36 on the sampling swab support cylinder 35 allows the sample to be evenly distributed in the sample extraction liquid in the sample extraction liquid bottle 31.
[0037] The sample addition control mechanism 6 includes a second pressing block 61, a latex inflation ball 62, a support plate 63, an air inlet check valve 66, an air inlet pipe 67, an air outlet check valve 68, and an inflation pipe 69. A second pressing groove is provided on the left side of the box body 21, and the second pressing block 61 is slidably connected in the second pressing groove. A support plate 63 is provided on the left side of the box body 21, and a latex inflation ball 62 is installed on the left side of the support plate 63. The left side of the latex inflation ball 62 abuts against the right side of the second pressing block 61. An air inlet pipe 67 is provided on the top of the latex inflation ball 62, and an air inlet check valve 66 is installed on the air inlet pipe 67. The right side of the latex inflation ball 62 is connected to one end of the inflation pipe 69 through the air outlet check valve 68. The other end of the inflation pipe 69 is connected to the top side of the sample extraction liquid bottle 31.
[0038] The sample addition control mechanism 6 also includes a telescopic rod 64 and a second return spring 65. The left ends of the two telescopic rods 64 are fixedly connected to the front and rear ends of the right side of the second pressing block 61, respectively. The right ends of the two telescopic rods 64 are fixedly connected to the front and rear ends of the support plate 63, respectively. Two second return springs 65 are respectively sleeved on the two telescopic rods 64. When the second pressing block 61 squeezes the latex inflatable ball 62, the telescopic rod 64 shortens and the second return spring 65 is compressed. After the second pressing block 61 is released, the second return spring 65 returns to its original length and the telescopic rod 64 also extends, pushing the second pressing block 61 out of the second pressing groove, which helps the latex inflatable ball 62 to return to its full state.
[0039] Press the second pressing block 61 into the box 21, and the latex inflation ball 62 is squeezed. The air in the latex inflation ball 62 enters the sample extraction liquid bottle 31 through the air outlet one-way valve 68 and the air inlet tube 69, increasing the pressure inside the sample extraction liquid bottle 31. The sample extraction liquid at the bottom of the sample extraction liquid bottle 31 is transported to the sample addition hole 113 through the sample addition delivery component 7. Release the second pressing block 61, and the latex inflation ball 62 draws in air through the air inlet one-way valve 66 and the air inlet tube 67 to return to its original state. Repeat this step until the sample extraction liquid fills the sample addition hole 113. This completes the addition of the sample extraction liquid into the sample addition hole 113. Using this method to add the sample extraction liquid is convenient to operate and does not easily spill.
[0040] The sample delivery assembly 7 includes a sample delivery tube 71, a connecting tube 72, and an addition channel 73. The addition channel 73 is provided inside the left end of the box cover 18. The right end of the addition channel 73 is connected to the sample addition hole 113. The left end of the addition channel 73 extends to the left side of the box cover 18. The connecting tube 72 is provided on the top right side of the box body 21. The right end of the connecting tube 72 is inserted into the left end of the addition channel 73. The left end of the connecting tube 72 is connected to one end of the sample delivery tube 71. The other end of the sample delivery tube 71 is connected to the bottom side of the sample extraction liquid bottle 31.
[0041] When installing the cover 18, the left end of the adding hole 73 needs to be matched with the right end of the connecting tube 72 first, and then the clip 110 is snapped into the slot 17.
[0042] After air is introduced into the sample extraction bottle 31, the internal pressure increases. The sample extraction liquid at the bottom of the sample extraction bottle 31 enters the addition channel 73 through the sample delivery tube 71 and the connecting tube 72, and finally enters the sample addition hole 113, contacting the test end on the left side of the test strip 15.
[0043] The sample handling box 2 also includes a stepped groove 22, a cover plate 23, and a snap-fit frame 24. The stepped groove 22 is located on the inner top side of the box body 21, and the snap-fit frame 24 is located on the outer side of the cover plate 23. The snap-fit frame 24 engages with the stepped groove 22. A circular hole corresponding to the bottle cap 38 is provided in the center of the cover plate 23. The stepped groove 22 and the snap-fit frame 24 work together to install the cover plate 23 on the top of the box body 21, concealing the internal components and maintaining an aesthetically pleasing appearance. The circular hole facilitates opening the bottle cap 38.
[0044] In use, first insert the sampling swab into the oral cavity and throat to collect a sample. Then, use the top sealing component to open the top of the sampling swab support component and insert the sampling swab tip downwards into the sampling swab support component. The tip of the sampling swab is simultaneously immersed in the sample extraction solution in the sample extraction solution bottle 31. Close the top of the sampling swab support component with the top sealing component. Then, the sample extraction enhancement mechanism 5 drives the sampling swab support component and the sampling swab inside the sampling swab support component to rotate relative to the sample extraction solution bottle 31, allowing the sample collected by the sampling swab tip to be fully mixed with the sample extraction solution in the sample extraction solution bottle 31 through the sampling swab support component. In this process, the sample extraction enhancement mechanism 5 achieves the purpose of quickly and efficiently mixing the sample collected by the sampling swab tip into the sample extract solution. The sample addition control mechanism 6 pumps air to pressurize the top of the sample extract solution bottle 31, allowing the sample extract solution mixed with the sample at the bottom of the sample extract solution bottle 31 to enter the sample addition hole 113 through the sample addition delivery component 7. The sample extract solution mixed with the sample at the end of the sample addition hole 113 permeates onto the test strip 15. The test result can be obtained by observing the test strip 15. Therefore, the operator does not need to hold the sample extract solution bottle 31 to add the sample extract solution separately, avoiding the sample extract solution from spilling, making the operation convenient.
[0045] Example 2, please refer to Figures 1 to 11 This embodiment provides a technical solution: a reagent kit. This embodiment has a roughly the same structure as Embodiment 1, the difference being: It also includes a swab head squeezing mechanism 4, which includes a spoke 41, a squeezing sleeve 42, a squeezing protrusion ring 43, and an exchange hole 44. The bottom of the sampling swab support cylinder 35 is connected to the top of the squeezing sleeve 42 through the spoke 41. The centers of the sampling swab support cylinder 35 and the squeezing sleeve 42 coincide. Multiple squeezing protrusion rings 43 are arranged vertically at equal intervals inside the squeezing sleeve 42. The number of squeezing protrusion rings 43 should be no less than three. Multiple exchange holes 44 are opened on the squeezing sleeve 42. The exchange holes 44 are located between two adjacent squeezing protrusion rings 43. The specific number of exchange holes 44 can be selected as needed. When the sampling swab tip is inserted into the sampling swab support cylinder 35, it can be directly inserted into the squeezing sleeve 42. The multiple squeezing protrusions 43 on the inner wall of the squeezing sleeve 42 can squeeze the sampling swab tip multiple times. The sampling swab tip will absorb and release the sample extract multiple times, thereby better mixing the sample from the sampling swab tip into the sample extract. The squeezing sleeve 42 will also rotate with the sampling swab support cylinder 35, and the sample will be more evenly distributed in the sample extract through the exchange hole 44.
[0046] Example 3, please refer to Figures 1 to 11 This embodiment provides a technical solution: a reagent kit. This embodiment has a roughly the same structure as Embodiment 2, the difference being: The kit also includes a sampling swab placement component 8, which comprises a placement slot 81, a sinking slot 82, a swab positioning seat 83, and a locking slot 84. The placement slot 81 is located on the side of the kit body 11, and the sinking slot 82 is located at the bottom of the placement slot 81. Two swab positioning seats 83 are located within the sinking slot 82, and a locking slot 84 is located on the upper middle part of the placement slot 81. Sampling swabs can be placed into the sinking slot 82 through the placement slot 81. The swab positioning seats 83 can limit the position of the sampling swab. When removing the sampling swab, the operator's fingers can remove the sampling swab through the locking slot 84. After the sampling swab is placed in the sinking slot 82, the entire kit needs to be sealed in plastic. The plastic seal is removed before use.
[0047] Please see Figures 1 to 11 A method for using a reagent kit includes the following steps: Step 1: Remove the sampling swab from the sink 82 and insert the tip of the sampling swab into the oral cavity and throat to collect a sample; Step 2: Remove the bottle cap 38 and rubber cap 39 from the top of the sampling swab support tube 35, and insert the completed sampling swab with the end facing down into the sampling swab support tube 35; Step 3: Insert the bottom end of the sampling swab into the squeezing sleeve 42. Multiple squeezing protrusions 43 on the inner wall of the squeezing sleeve 42 squeeze the end of the sampling swab multiple times. The end of the sampling swab absorbs and releases the sample extract multiple times, mixing the sample from the end of the sampling swab into the sample extract around the squeezing sleeve 42. Step 4: Replace bottle cap 38 and rubber cap 39, with the bottom of rubber cap 39 pressing against the top of the sampling swab; Step 5: The operator presses the two pressing blocks 51 into the box 21 by hand, causing the two racks 52 to move closer together. The extraction gear 33 drives the sampling swab support cylinder 35 to rotate clockwise relative to the sample extraction liquid bottle 31. At this time, the two reset springs 54 are compressed. When the two pressing blocks 51 are released, the two reset springs 54 stretch due to elasticity, and the two pressing blocks 51 extend out from the two pressing slots. The two racks 52 move away from each other, and the extraction gear 33 drives the sampling swab support cylinder 35 to rotate counterclockwise relative to the sample extraction liquid bottle 31. The sampling swab support cylinder 35 rotates back and forth relative to the sample extraction liquid bottle 31, causing the sample at the end of the sampling swab in the sampling swab support cylinder 35 to mix into the sample extraction liquid. The sample is evenly distributed in the sample extraction liquid in the sample extraction liquid bottle 31 through the exchange slot 36 on the sampling swab support cylinder 35. Step six: When the sampling swab support tube 35 rotates relative to the sample extraction liquid bottle 31, it also drives the stirring blade 37 to rotate. The stirring blade 37 stirs the sample extraction liquid, improving the uniformity of sample distribution in the sample extraction liquid. Step 7: Press the second pressing block 61 into the box 21. The latex inflation ball 62 is squeezed. The air in the latex inflation ball 62 enters the sample extraction liquid bottle 31 through the air outlet one-way valve 68 and the inflation tube 69. The air pressure in the sample extraction liquid bottle 31 increases. The sample extraction liquid at the bottom of the sample extraction liquid bottle 31 is transported to the sample addition hole 113 through the sample addition and delivery component 7. Step 8: The sample extract penetrates the test strip 15 from left to right. Observe the control line and test line on the test strip 15 through the observation window 112. Check whether the test is effective through the control line and check whether the sample contains the target analyte through the test line.
