Description

Technical Field

[0001] This utility model relates to a detection box, and more particularly to a sample collection and detection box. Background Technology

[0002] Parasites are pathogenic lower eukaryotic organisms that can act as pathogens or vectors for disease transmission. Parasites are characterized by living within or attached to a host to obtain the nutrients or shelter necessary for their survival, development, or reproduction. Many small animals live parasitically, attaching themselves to animals larger than themselves; parasites can alter the behavior of their hosts to better facilitate their own reproduction and survival. In humans, infection by certain brain parasites, such as Toxoplasma gondii, which lives in the brain for life, can impair responsiveness.

[0003] Traditional experimental kits typically place multiple sampling tubes close together for ease of management. However, this storage method has several drawbacks in practical use. For example, in terms of handling, the dense arrangement of tubes requires careful attention to avoid bumping into other tubes, especially when multiple tubes need to be handled quickly and consecutively. This inconvenience reduces work efficiency and prolongs test preparation time. Furthermore, the small spacing between tubes limits finger dexterity, making it difficult to accurately remove a single tube and increasing the risk of bumping into surrounding tubes. This can lead to collisions between tubes, potentially causing breakage or leakage, thus affecting sample collection and testing. Additionally, the sampling tube aperture diameter in the kit is usually larger than the tube diameter itself. During transport, the tubes are prone to shaking, which can cause them to collide. For some fragile tubes, this can lead to breakage or leakage, affecting the detected genes. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to provide a sample collection and testing box that facilitates the removal of the sampling tubes inside the box and prevents the sampling tubes from colliding with each other due to shaking during transportation, which could lead to problems such as breakage and leakage.

[0005] Technical Solution: The sample collection and testing box includes: a main body, a fixing plate installed inside the main body, multiple sampling tubes arranged on one side of the fixing plate, a lifting mechanism correspondingly arranged below the sampling tubes, the lifting mechanism including a sleeve, a slider slidably arranged inside the sleeve, one end of the slider being fixedly connected to a pressure plate, the other end being connected to a guide groove, the guide groove being connected to a sliding plate, a groove being formed at the end of the guide groove near the slider, a top groove being provided at one end of the top of the sleeve, a limiting groove being provided at the other end, a support rod being slidably installed in the middle of the top groove, a top plate being fixedly installed at the upper end of the support rod, a sliding rod being fixedly installed on one side of the lower end of the support rod, the sliding rod being slidable relative to the guide groove, the guide groove being horizontal and then inclined at the side near the sliding plate, and a groove being formed at the end near the slider, the sliding rod being engaged when it slides to the groove, the upper end of the top plate abutting against the bottom of the sampling tube, a limiting block being installed at the upper end of the slider, the limiting block being engaged with the limiting groove.

[0006] Furthermore, baffles are fixedly installed on both sides of the lifting mechanism, located on the opposite side of the connecting guide groove of the slide plate.

[0007] Furthermore, an auxiliary material fixing groove is provided on the other side of the main body, and a test strip fixing groove is provided at one end of the auxiliary material fixing groove.

[0008] Furthermore, sample dilution solution fixing tanks are provided at both ends on the other side of the auxiliary material fixing tank.

[0009] Furthermore, the upper end of the main body is rotatably connected to a box lid via a hinge, and one end of the box lid has an embedded handle.

[0010] Furthermore, the fixing plate is provided with a placement slot for placing sampling tubes, and a rubber ring is installed at the upper end of the placement slot. A label is affixed to one side of each sampling tube.

[0011] Furthermore, lifting rods are fixedly installed at both ends of the main body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) In use, each sampling tube corresponds to an individual lifting mechanism. When a sampling tube needs to be picked up, the corresponding pressure plate is pushed to drive the slider to slide inside the sleeve. The slide plate connected to the slider moves accordingly, and the guide groove on the slide plate guides the slide rod to move, so that the support rod slides upward in the top groove, lifting the top plate and thus lifting the sampling tube to a certain height. Compared with the traditional densely arranged sampling tubes, the staff can easily and accurately pick up a single sampling tube, which can effectively avoid collisions between sampling tubes, thereby greatly improving the picking efficiency. Especially in scenarios where multiple sampling tubes need to be picked up quickly and continuously, it can effectively shorten the detection preparation time.

[0014] (2) When the sampling tube is in use, the top plate abuts against the bottom of the sampling tube after the sampling tube is placed in place, providing support and limiting the sampling tube. At the same time, the baffle prevents the slide from moving randomly, keeps the support rod stable, and avoids the sampling tube from shaking due to the top plate falling unexpectedly. Even if the reagent kit is subjected to vibration or bumps during transportation, the sampling tube can be relatively stably fixed in its original position, greatly reducing the risk of breakage and leakage caused by mutual collision due to shaking, ensuring that the detected genes are not affected, and guaranteeing the integrity and reliability of the test sample.

[0023] Please see Figures 1-6As shown, the sample collection and detection kit of this embodiment includes:

[0024] The experimental kit body 1 has a fixed plate 13 inside. Multiple sampling tubes 16 are inserted into the middle of the fixed plate 13. Each sampling tube 16 has a separate lifting mechanism 2 at its lower end. The lifting mechanism 2 includes a sleeve 21, with a slider 28 slidably engaged in the middle of the sleeve 21. A pressure plate 30 is fixedly installed at one end of the slider 28, and the other end is connected to a guide groove 32. The guide groove 32 is connected to a sliding plate 31. A groove 33 is formed at the end of the guide groove 32 near the slider 28. A top groove 22 is provided at one end of the top of the sleeve 21, and a limiting groove 23 is provided at the other end. A support rod 25 is slidably engaged in the middle of the top groove 22, and the upper end of the support rod 25 is fixed... A top plate 26 is fixedly installed, and a slide rod 27 is fixedly installed on one side of the lower end of the support rod 25. The slide rod 27 can slide relative to the guide groove 32. The guide groove 32 is horizontal and then inclined on the side near the slide plate 31. The end near the slider 28 is a groove 33. The slide rod 27 slides to the groove 33 and engages. The upper end of the top plate 26 abuts against the bottom of the sampling tube 16. A limit block 29 is fixedly installed in the middle of the upper end of the slider 28. The limit block 29 is slidably engaged with the limit groove 23. Baffles 24 are fixedly installed on both sides of the lifting mechanism 2, located on the opposite side of the guide groove 32 of the slide plate 31, to prevent random sliding when stationary.

[0025] As can be seen from the above, each sampling tube 16 corresponds to an individual lifting mechanism 2. When it is necessary to pick up the sampling tube 16, the pressure plate 30 is pushed, and the pressure plate 30 drives the slider 28 to slide inside the sleeve 21. The slide plate 31 connected to the slider 28 moves accordingly, and the guide groove 32 connected to the slide plate 31 moves accordingly, thereby guiding the slide rod 27 to slide. The slide rod 27 slides upward along the slope. As the height increases, the support rod 25 slides upward in the top groove 22, lifting the top plate 26, and thus lifting the sampling tube 16 out to a certain height. When the slide rod 27 reaches above the groove 33, it is locked. Compared with the traditional densely arranged sampling tubes 16, the staff no longer needs to carefully avoid touching other sampling tubes 16. They can easily and accurately pick up a single sampling tube 16, which greatly improves the picking efficiency. Especially in scenarios where multiple sampling tubes 16 need to be picked up quickly and continuously, it can effectively shorten the test preparation time. During transportation, the sampling tubes 16 are usually easy to shake and collide with each other in the reagent kit, but in this design, Once the sampling tube 16 is in place, the top plate 26 abuts against the bottom of the sampling tube 16, providing support and limiting the sampling tube 16. When the entire device is not in use, the baffle 24 inside the lifting mechanism 2 can limit the sliding plate 31, the slider 28, and the pressure plate 30. The position of the baffle 24 is carefully designed, and they fit tightly against one end of the moving path of the sliding plate 31, preventing the sliding plate 31 from moving arbitrarily without human operation. This ensures that the entire lifting mechanism 2 remains stable when the reagent kit is stationary, avoiding accidental operation of the lifting mechanism 2 due to accidental touch or vibration, thereby preventing the sampling tube 16 from being accidentally lifted. This ensures the safety and reliability of the reagent kit during daily storage and transportation. When the sliding plate 31 moves towards the baffle 24 under pressure, the baffle 24 can be easily broken when subjected to continuous inward squeezing force, allowing the user to smoothly push the lifting mechanism 2 to lift the sampling tube 16, making it convenient and quick to pick up the sampling tube 16.

[0026] refer to Figures 1-3 As shown, an auxiliary material fixing groove 18 is provided in the middle of the other side of the upper end of the experimental box body 1. A test strip fixing groove 20 is provided on one side of the auxiliary material fixing groove 18. Sample diluent fixing grooves 19 are provided at both ends of the other side of the auxiliary material fixing groove 18. The upper end of the experimental box body 1 is connected to the box cover 11 by a hinge. An embedded handle 12 is provided at one end of the box cover 11. Multiple placement grooves 14 are evenly provided in the middle of the fixing plate 13. Rubber rings 15 are fixedly installed at the upper end of the multiple placement grooves 14. A label 17 is pasted on one side of each sampling tube 16 inserted in the middle of the fixing plate 13. Multiple sampling tubes 16 are respectively inserted into the middle of the rubber rings 15 and the placement grooves 14. Lifting rods 10 are fixedly installed at both ends of the experimental box body 1.

[0027] As can be seen from the above, the auxiliary material fixing slot 18 is specifically used to place various auxiliary tools, such as disposable gloves, sampling spoons, pipettes, etc. The test strip fixing slot 20 and the sample diluent fixing slot 19 respectively position the test strip and sample diluent, allowing the testing personnel to quickly find the required tools during use, avoiding messy searching in the reagent kit, thereby improving work efficiency. More specifically, the threaded interface at the top of the sample tube 16 adopts the standard diameter of the market and is compatible with common silicone dropper accessories. Users can choose the following two operating modes according to actual needs:

[0028] 1) Laboratory pre-mixing mode: Users can choose to mix the sample diluent with the test reagent in the laboratory in advance, inject it into the silicone dropper and seal it. Then, use the cap fixed on the dropper to screw the threaded end of the dropper into the top of the sample tube 16. The built-in sealing plug of the dropper can prevent leakage during transportation or storage. When using it on site, press the dropper head to directly add the premixed solution to the test strip without the need to take additional diluent.

[0029] 2) On-site mixing mode: If the user needs to mix on-site or outdoors, first prepare the required concentration of diluent in the sample diluent fixing tank 19, use the sampling spoon or pipette in the auxiliary material fixing tank 18 to measure the diluent according to the ratio and transfer it to the sample tube 16, shake the sample tube 16 to mix the sample and diluent thoroughly, and then use the pipette to draw the mixture and add it to the test strip for detection.

[0030] The placement slot 14 on the fixing plate 13, together with the rubber ring 15, fixes the sampling tube 16. The rubber ring 15 has good elasticity and can fit tightly against the outer wall of the sampling tube 16. It can not only prevent the sampling tube 16 from shaking inside the kit, but also play a certain role in buffering, reducing the risk of damage to the sampling tube 16 during transportation and ensuring the safety of the sampling tube 16 and its internal samples. The label 17 pasted on one side of each sampling tube 16 makes it convenient to record and view sample-related information, such as sample number, collection time, collection object, etc. The box cover 11 is connected by a hinge, which is convenient to open and close and can effectively protect the various components inside the kit from external factors such as dust and moisture. At the same time, the lifting rods 10 fixedly installed at both ends of the experimental box body 1 further facilitate handling or long-distance transportation, so that the kit can be easily transferred in different scenarios.

[0031] Working principle:

[0032] like Figure 1-6As shown, this rapid detection colloidal gold kit for Giardia lamblia covers a series of steps including sample collection, reagent storage and retrieval, detection operation, and result interpretation. The sampling tube 16 is inserted into the placement slot 14 of the fixing plate 13. The rubber ring 15 at the upper end of the placement slot 14 tightly fits against the outer wall of the sampling tube 16, providing stability and cushioning to prevent the sampling tube 16 from shaking or colliding during transportation. When the sampling tube 16 needs to be retrieved, the pressure plate 30 of the corresponding lifting mechanism 2 is pressed. The pressure plate 30 pushes the slider 28 to slide within the sleeve 21, and the sliding plate 31 connected to the slider 28 moves synchronously. The guide groove 32 on the sliding plate 31 guides the sliding rod 27 to move, causing the support rod 25 to slide upward within the top groove 22, thereby lifting the top plate 26. The top plate 26 lifts the sampling tube 16 to a certain height, making it convenient for the testing personnel to retrieve. When not in use, the baffle 24 inside the lifting mechanism 2 limits the sliding plate 31, the slider 28, and the pressure plate 30 to prevent accidental operation. When in use, the sliding plate 31 can move and break the baffle 24. The testing personnel use auxiliary tools such as a sampling spoon in the auxiliary material fixing slot 18 inside the reagent kit to collect fecal samples and place them into the sampling tube 16. The label 17 pasted on one side of the sampling tube 16 is used to record sample information for easy subsequent tracking and management. The auxiliary material fixing slot 18 stores auxiliary tools such as disposable gloves and pipettes. The test strip fixing slot 20 holds the test strips. The sample diluent fixing slot 19 stores the sample diluent. Testing personnel can retrieve reagents and tools from the corresponding fixed slots as needed. These slots ensure organized storage and facilitate quick retrieval of required items. The sample from sampling tube 16, containing the collected fecal sample, is mixed with an appropriate amount of sample diluent in the fixed slot 19 according to the instructions. The sample and diluent are thoroughly mixed by shaking to prepare the required sample solution. An appropriate amount of the prepared sample solution is then drawn up with a pipette and added to the sample pad of the test strip. The test strip is then observed within the specified time. If both the T and C lines show red bands, the result is positive, indicating the presence of Giardia antigen in the sample. If only the C line shows a red band and the T line does not develop color, the result is negative. If the C line does not show a red band, regardless of whether the T line develops color, the test result is invalid and must be repeated.
