Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a liver function testing kit that is resistant to evaporation and interference. Background Technology
[0002] In the fields of clinical medicine and biological testing, liver function testing is a key means of assessing liver health and diagnosing liver diseases (such as hepatitis, cirrhosis, and liver damage). Liver function testing kits are specialized tools developed to efficiently and accurately meet these testing needs. The core purpose of these kits is to achieve quantitative or qualitative detection of key liver function indicators in human blood, serum, and other samples, covering commonly used indicators such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, direct bilirubin, albumin, and alkaline phosphatase (ALP), providing data support for clinical assessment of whether liver metabolism, synthesis, and detoxification functions are normal. However, test tubes are usually labeled with sample information for traceability. In practice, when the sample volume is large, test tubes are often stored together. Operators need to pick them up and check the label information multiple times to locate the target test tube. This process not only prolongs the time cost of sample pretreatment, but also makes it inconvenient to pick up and put down test tubes with existing liver function test kits.
[0003] Therefore, this invention provides a liver function testing kit that is resistant to evaporation and interference, in order to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a liver function test kit that is resistant to evaporation and interference. This solves the problem mentioned above, where operators need to pick up and verify the label information multiple times to locate the target test tube. This process not only prolongs the time cost of sample pretreatment, but also makes it inconvenient to handle test tubes in existing liver function test kits.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a liver function testing kit resistant to evaporation and interference, comprising a kit, a kit cap, and test tubes, and further comprising... The picking mechanism is located at the bottom of the reagent kit. The picking mechanism includes a pull rod movably connected to one side of the reagent kit, and the pull rods are symmetrically arranged on both sides of the reagent kit. The pull rod is movably connected to a lifting component through a connecting rod, and the other end of the lifting component is fixedly connected to a support base plate. When the handle is pulled to both sides, the pull rod is moved to both ends of the reagent kit. At this time, the connecting rod on the handle pulls one of the rotating rods to move outward. At this time, the first and second support arms open outward under the action of the annular groove, thereby lifting the support base plate hinged on the other rotating rod upward, thereby lifting the test tube on the support base plate outward of the reagent kit. An anti-evaporation mechanism includes fixed bases for preventing evaporation, the fixed bases being equidistantly arrayed on the upper surface of a support base plate.
[0006] Preferably, a magnetic ring for fixing is fixedly connected between the reagent kit and the reagent kit cap, and a rubber gasket for sealing is fixedly connected to the inner side of the magnetic ring.
[0007] Preferably, handles are fixedly connected to the sides of both pull rods, and a test tube rack for limiting position is also fixedly connected to the inner side of the reagent kit.
[0008] Preferably, the lifting assembly includes two rotating rods, one of which is rotatably connected to the other end of a connecting rod, and a support arm 1 and a support arm 2 are rotatably connected to one of the rotating rods respectively. The support arm 2 is movably connected to the bottom of the reagent kit via a straight rod, and the other end of the support arm 1 is rotatably connected to another rotating rod.
[0009] Preferably, the inner surface of the reagent kit is provided with annular grooves that match the rotating rod, and the two sides of the reagent kit are provided with sliding grooves that match the connecting rod.
[0010] Preferably, the anti-evaporation mechanism further includes metal contacts fixed at both ends of the fixing base, and a limiting groove matching the metal contacts is provided on the inner side of the reagent kit. A thermostat is provided inside the fixing base, and a metal connector matching the metal contacts is provided on the lower end face of the limiting groove, so that when the metal contacts and the metal connectors come into contact, the metal contacts, the metal connectors, the thermostat and the battery inside the reagent kit form a closed circuit to control the temperature of the test tube and prevent evaporation.
[0011] This invention provides a liver function testing kit that is resistant to evaporation and interference. Compared with the prior art, it has the following advantages: (1) The liver function test kit that is evaporation-proof and interference-proof is equipped with a symmetrically assembled pull rod, handle, connecting rod, rotating rod, support arm one, support arm two and support base plate. The test tube rack is provided inside the kit. When the test tube needs to be taken out, the operator pulls the handles on both sides outward, which can drive the pull rod to slide along the slide groove. Then, the connecting rod pulls the rotating rod to move along the ring groove, so that support arm one and support arm two open outward, and simultaneously lifts the support base plate upward, so that the upper end of the test tube extends out of the kit opening. The tube can be quickly located and taken out without having to pick up and check the label multiple times.
[0012] (2) When the reagent kit is closed, the magnetic ring between the reagent kit and the lid is magnetically attracted and fixed, and the inner rubber pad fills the gap to form a sealed space, which isolates external dust pollution and air circulation. When the support base plate descends naturally, the metal buttons at both ends of the fixing seat are embedded in the limiting groove and contact the metal connector to form a closed circuit to start the thermostat, which stabilizes the sample environment within the preset temperature range. This avoids the sample evaporation caused by excessive temperature and prevents temperature fluctuations from changing the properties of indicators such as ALT, AST and bilirubin, thereby reducing the interference of external factors on the detection.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0016] Please see Figures 1 to 4 A liver function testing kit resistant to evaporation and interference, comprising a kit 1, a kit cap 2, and a test tube 4, and further comprising... The picking mechanism 5 is located at the bottom of the reagent kit 1. The picking mechanism 5 includes a pull rod 51 movably connected to one side of the reagent kit 1, and the pull rod 51 is symmetrically arranged on both sides of the reagent kit 1. The pull rod 51 is movably connected to a lifting component through a connecting rod 53, and the other end of the lifting component is fixedly connected to a support base plate 59. When the handle 52 is pulled to both sides to move the pull rod 51 to both ends of the reagent kit 1, the connecting rod 53 on the handle 52 pulls one of the rotating rods 54 to move outward. At this time, the first support arm 55 and the second support arm 56 open outward under the action of the annular groove 57, thereby lifting the support base plate 59 hinged on the other rotating rod 54 upward, thereby lifting the test tube 4 on the support base plate 59 outward to the outside of the reagent kit 1. Handles 52 are fixedly connected to the sides of both pull rods 51, and a test tube rack 510 for limiting position is fixedly connected to the inner side of the reagent kit 1. The lifting assembly includes two rotating rods 54, one of which is rotatably connected to the other end of the connecting rod 53, and one of which is rotatably connected to a support arm 55 and a support arm 56 respectively. The support arm 56 is movably connected to the bottom of the reagent kit 1 through a straight rod, and the other end of the support arm 55 is rotatably connected to another rotating rod 54. The inner side of the reagent kit 1 is provided with annular grooves 57 that match the rotating rods 54, and the two sides of the reagent kit 1 are provided with sliding grooves 58 that match the connecting rods 53. During operation, first place the test tube 4 containing the liver function test sample (such as blood or serum) in the corresponding position on the upper surface of the support base plate 59. At this time, the test tube rack 510 fixed on the inner side of the reagent kit 1 will fit against the middle area of the test tube 4, forming a lateral limit on the test tube 4, preventing the sample from spilling or the test tube 4 from tipping over due to shaking inside the reagent kit 1. When the operator needs to remove the target test tube 4, hold the handles 52 on both sides of the reagent kit 1 with both hands and apply a pulling force away from the central axis of the reagent kit 1. The pull rod 51 is fixedly connected to the side of the reagent kit 1, and the pull rod 51 is movably mounted on the side of the reagent kit 1. The pulling force will drive the pull rod 51 to slide linearly along the preset sliding grooves 58 on both sides of the reagent kit 1 (the sliding grooves 58 provide guidance for the movement of the pull rod 51 and the subsequent connecting rod 53 to prevent deviation). As the pull rod 51 slides outward, the connecting rod 53 connected to one end will move synchronously and pull one of the rotating rods 54 that is rotatably connected to it. Because the inner side of the reagent kit 1 has an annular groove 57 that matches the shape of the rotating rod 54, the rotating rod 54 can only move along the arc trajectory of the annular groove 57. As the rod 54 moves, it slides outward along the annular groove 57, thereby causing the first support arm 55 and the second support arm 56, which are rotatably connected to it, to move synchronously. The second support arm 56 is movably connected to the bottom inner wall of the reagent kit 1 via a straight rod, which acts as a fixed fulcrum for the second support arm 56, restricting the displacement direction of one end. Meanwhile, the first support arm 55 pushes the other rod 54 to slide in the same direction along the annular groove 57, causing the first support arm 55 and the second support arm 56 to be in an "outward opening" posture, generating an upward supporting force, thereby pushing the support base plate. 59 is raised vertically upwards until the upper end of test tube 4 extends beyond the top opening of reagent kit 1. At this point, the operator can directly grasp the upper end of test tube 4 and easily remove it for subsequent testing. If it is not necessary to remove the tube or after removing the tube, push handle 52 towards the center of reagent kit 1. This will cause pull rod 51, connecting rod 53 and rotating rod 54 to move in the opposite direction. Support arm 1 55 and support arm 2 56 will retract inwards, and support base plate 59 will descend and reset. Test tube 4 will return to the inside of reagent kit 1, and test tube rack 510 will restore the limiting and fixing of test tube 4. Example
[0017] Please see Figures 1 to 4This embodiment provides a technical solution based on Embodiment 1: an anti-evaporation mechanism 6, including a fixing seat 61 for anti-evaporation, the fixing seats 61 are equidistantly arrayed on the upper surface of the support base plate 59, a magnetic ring 3 for fixing is fixedly connected between the reagent kit 1 and the reagent kit cover 2, and a rubber gasket for sealing is fixedly connected to the inner side of the magnetic ring 3. The anti-evaporation mechanism 6 also includes metal contacts 62 fixed at both ends of the fixing seat 61, and a limiting groove 63 matching the metal contacts 62 is opened on the inner side of the reagent kit 1. A thermostat 64 is provided inside the fixing seat 61, and a metal connector matching the metal contacts 62 is provided on the lower end surface of the limiting groove 63, so that when the metal contacts 62 contact the metal connector, the metal contacts 62, the metal connector, the thermostat 64 and the battery inside the reagent kit 1 form a closed circuit to control the temperature of the test tube 4 and prevent evaporation. During operation, after test tube 4 is placed in the fixing seat 61 on the support base plate 59 (the inner wall of the fixing seat 61 fits against the outer wall of test tube 4, positioning the bottom of test tube 4), the operator closes the reagent kit cap 2. At this time, the magnetic ring 3 between the top edge of reagent kit 1 and the bottom edge of reagent kit cap 2 will attract each other through magnetic force, making reagent kit cap 2 tightly fixed to the main body of reagent kit 1, preventing reagent kit cap 2 from accidentally falling off during transportation or storage. At the same time, the rubber gasket attached to the inner side of the magnetic ring 3 will be squeezed, tightly filling the gap between reagent kit 1 and reagent kit cap 2, forming a sealed space, reducing the flow of air between the inside of reagent kit 1 and the outside air, and preventing external dust and impurities. When the sample is contaminated, and the support base 59 is in a naturally descending state (not raised), the protruding metal contacts 62 at both ends of the fixing seat 61 will fit precisely into the limiting grooves 63 opened on the inner side of the reagent kit 1, and the lower end face of the metal contacts 62 will be in complete contact with the metal connector pre-set at the bottom of the limiting groove 63. Since the reagent kit 1 has a built-in power supply battery (used to power the thermostat 64), when the metal contacts 62 and the metal connectors come into contact, a closed circuit is formed between the battery, the metal connectors, the metal contacts 62, the thermostat 64, and the battery. The thermostat 64 then starts working. The thermostat 64 will operate according to the preservation requirements of the liver function test sample (the thermostat 64 uses a Soviet-made product). The Zhoujiemei DB series dry thermostat features a built-in thermistor (64) that monitors the temperature around the test tubes (4) inside the reagent kit (1) in real time. It converts the temperature signal into a recognizable electrical signal. The thermostat sets the required constant temperature range for liver function test samples and compares the real-time temperature signal with a preset threshold. For most samples, a constant temperature of 2-8℃ or room temperature is required. The temperature is set by the operator based on actual usage. If the real-time temperature is lower than the preset value, the thermostat (64) triggers the dry heating module (DBA05 module) to power on, raising the temperature through non-contact heating. Once the preset value is reached, the heating module de-energizes, using residual heat to maintain a stable temperature. The mounting base (61) and surrounding area are then... The temperature of the area is stabilized within a preset constant range. Temperature control prevents the sample from evaporating due to excessive temperature and also prevents temperature fluctuations from altering the properties of detection indicators such as ALT, AST, and bilirubin in the sample, thereby reducing the impact of temperature interference on the accuracy of subsequent test results. When it is necessary to open the reagent kit cover 2 to take out or put in the test tube 4, the process of opening the reagent kit cover 2 will destroy the magnetic attraction of the magnetic ring 3, and the sealing structure will be temporarily released. If the support base plate 59 is lifted by the picking mechanism 5 at this time, the fixing seat 61 will rise synchronously with the support base plate 59, the metal touch 62 will separate from the metal connector in the limiting groove 63, the closed circuit will be broken, and the thermostat 64 will automatically stop working.
[0018] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0019] Working principle: During operation, the initial placement of sample tubes 4 is completed first: the test tubes 4 containing liver function test samples (blood, serum, etc.) are placed one by one into the fixing seat 61 on the internal support base plate 59 of the reagent kit 1. The fixing seat 61 positions the bottom of the test tube 4, while the test tube rack 510 inside the reagent kit 1 limits the middle of the test tube 4. Then, the reagent kit cap 2 is closed. The magnetic ring 3 between the reagent kit 1 and the reagent kit cap 2 is fixed by magnetic attraction. The rubber pad fills the gap to form a sealed space, isolating external contamination and air circulation. At the same time, the metal contact 62 of the fixing seat 61 is embedded in the limiting groove 63 and contacts the metal connector, closing the circuit and starting the thermostat 64 to stabilize the sample environment temperature at the preset temperature. To prevent sample evaporation and temperature interference, when test tube 4 needs to be removed for testing, the operator holds the handles 52 on both sides of reagent kit 1 with both hands and pulls them outward to drive the pull rod 51 to slide along the slide groove 58. The connecting rod 53 then pulls the rotating rod 54 to move along the ring groove 57. Support arm 1 55 and support arm 2 56 open outward and raise the support base plate 59. The upper end of test tube 4 extends out of the opening of reagent kit 1, and the tube can be directly removed for testing. After the test is completed, test tube 4 is placed back into the fixed seat 61, and the handle 52 is pushed to reset the support base plate 59. The metal contact button 62 contacts the metal connector again, the thermostat 64 restarts, the reagent kit cover 2 is closed, and the magnetic ring 3 re-adsorbs and seals, completing the sample storage and preservation.
