Description

Technical Field

[0001] The invention relates to the technical field of liquid dripping devices, in particular to a liquid dripping device for endocrine sample classification. Background Art

[0002] In the field of endocrinology, sample collection, processing and testing are crucial links in scientific research and clinical work. Endocrine samples, such as serum, plasma, urine, cell culture supernatant and tissue homogenate, are rich in biologically active substances and have a significant impact on the regulation of the body's internal environment. Therefore, they occupy an important position in research and diagnosis.

[0003] After being processed, the above-mentioned different samples need to be dropped into different collection containers, such as dedicated test tubes (centrifuge tubes) or test plates. In actual work, when a patient needs to undergo multiple tests, the samples need to be dropped into dedicated centrifuge tubes. When immunoassays or high-throughput screening are required, the samples need to be dropped into test plates.

[0004] However, existing instruments are generally capable of performing dripping work in a single collection container, that is, samples that need to be dripped into test tubes must be added to the dripping device applied to the test tubes, and samples that need to be dripped onto test plates must be added to the dripping device applied to the test plates. This is not only cumbersome, time-consuming and labor-intensive, increasing the workload of medical staff, but also inefficient and not conducive to processing a large number of samples. In addition, medical staff may mistakenly place samples into the dripping device, further affecting the normal progress of the dripping work. For this reason, we propose a dripping device for endocrine sample classification. Summary of the invention

[0051] A switchable dripping unit 3 is disposed inside the body 1 and is used to add sample solution and cleaning solution into the transfer box 13 and adjust the bottom dripping mode according to the collection container;

[0052] The switchable dripping unit 3 includes a fixing plate 31 arranged on the body 1, the sample box 11 and the cleaning liquid box 12 are both arranged on the fixing plate 31, the sample box 11 and the cleaning liquid box 12 are both provided with a liquid filling port 32, the transfer box 13 is provided with a connecting pipe 33 connected to the inside, the connecting pipe 33 is provided with a fixing groove 34, the bottom of the sample box 11 and the cleaning liquid box 12 are both provided with a liquid adding member 4 used in conjunction with the connecting pipe 33, which is used to add sample solution and cleaning liquid into the transfer box 13, the bottom of the transfer box 13 is provided with a metering component 5, which is used to control the amount of liquid discharged from the transfer box 13, and the body 1 is provided with a replacement component 9, which is used to replace the dripping tool at the bottom of the metering component 5;

[0053] The liquid adding member 4 includes a liquid outlet pipe 41 arranged at the bottom of the sample box 11, a fixing ring 42 is arranged in the liquid outlet pipe 41, a return spring 43 is arranged on the fixing ring 42, a sealing plate 44 is arranged at the end of the return spring 43, the connecting pipe 33 can lift the sealing plate 44, and the connecting pipe 33 and the fixing ring 42 are interference fit, a convex ring is arranged on the sealing plate 44, and a concave ring is opened inside the transfer box 13, and the arrangement of the concave ring and the convex ring improves the sealing performance of the liquid outlet pipe 41;

[0054] The metering assembly 5 includes a metering box 51 arranged at the bottom of the transfer box 13, the metering box 51 and the transfer box 13 are connected by a pipeline, a rotating shaft 52 is rotatably arranged in the metering box 51, a metering disk 53 is arranged on the rotating shaft 52, two metering grooves 54 are arranged on the metering disk 53, one is used to drip samples into the test tube, and the other is used to drip samples into the detection plate, a dropper 55 is arranged at the bottom of the metering box 51, a driving motor 56 is arranged on the metering, and the driving motor 56 is connected to the rotating shaft 52, a liquid injection part 6 is arranged in the body 1, which is used to add a certain volume of solution into the metering groove 54, and a pressure part 7 is arranged on the metering box 51, which is used to apply pressure to the metering groove 54 when dripping samples into the detection plate;

[0055] The liquid injection member 6 includes a pump body 61 disposed in the transfer box 13, which is used to pressurize the solution in the transfer box 13 and enter the metering tank 54. The metering tanks 54 are each provided with an adjustment plate 62. The adjustment plate 62 in the metering tank 54 for dripping the sample to the detection plate is provided with a check valve 63. Another adjustment plate 62 is provided with a through hole 64.

[0056] The pressure piece 7 includes a magnet 71 arranged on the adjustment plate 62 near the one side of the one-way valve, a magnet 72 with opposite polarity to the magnet 71 is arranged near the position of the dropper 55 of the metering box 51, and elastic pieces 8 are arranged on both sides of the adjustment plate 62 near the one side of the one-way valve for elastic reset. The dripping of the detection plate generally needs to be carried out using a capillary, so the solution in the metering tank 54 is difficult to be discharged under the action of gravity, and then a pressure piece 7 is arranged, and two magnets 71 and 72 with opposite polarities are used to effectively apply pressure to the metering tank 54, thereby ensuring the normal discharge of the sample. In this scheme, the certain capacity in the metering tank 54 is set to 1ml, but it is not limited. Generally, the sample dripped on the detection plate is about 1 / 20 of the certain capacity. Therefore, the solution in the metering tank 54 can drip on multiple detection plates. If there is any surplus, it is directly discharged into the waste box 93. Different capacities are required in the test tube according to different subsequent projects, which can be set by yourself;

[0057] The elastic member 8 includes two elastic ropes 81 respectively arranged on both sides of the adjustment plate 62 near the one-way valve. The ends of the elastic ropes 81 are connected to the metering disk 53 to ensure that the adjustment plate 62 can be normally reset while ensuring the rotation of the metering disk 53.

[0058] The replacement part 9 includes a detection plate rack 91 and a test tube rack 92 arranged in the machine body, a waste box 93 is arranged in the machine body, a rejection plate 94 is arranged in the machine body for rejecting the dripping tool on the dripping tube 55, a mounting frame 95 for storing the dripping tool is arranged in the machine body, and a plurality of rotating side doors are arranged on the machine body for directly taking out the waste box 93, the mounting frame 95, etc.

[0059] When in use, the motion control unit 2 is driven by the screw rod 1 22, the screw rod 25 and the screw rod 3 28 on the fixed frame 21 to cooperate with the first motor 23, the second motor 26 and the third motor 29 to drive the horizontal frame 24, the longitudinal frame 27 and the shift seat 210 to slide on the fixed frame 21, the horizontal frame 24 and the longitudinal frame 27, thereby driving the transfer box 13 to move three-dimensionally inside the body 1, so as to accurately locate it under the sample box 11 or the cleaning liquid box 12 that needs to be operated;

[0060] When the transfer box 13 moves to the bottom of the designated sample box 11, the connecting tube 33 on the transfer box 13 docks with the liquid outlet tube 41 at the bottom of the sample box 11, and the sealing plate 44 in the liquid outlet tube 41 is lifted up by the connecting tube 33. At the same time, the connecting tube 33 and the fixing ring 42 have an interference fit to ensure the sealing performance. At this time, the sample solution flows into the transfer box 13 through the liquid outlet tube 41. The operation process of the cleaning liquid box 12 is the same as that of the sample box 11, and is used to add cleaning liquid into the transfer box 13.

[0061] The sample solution or cleaning solution in the transfer box 13 is pressurized by the pump body 61 and enters the metering box 51 through the pipeline. The metering box 51 is provided with a rotating shaft 52 and a metering disk 53. The metering disk 53 is provided with two metering grooves 54, which are used to drip samples to the test tube and the detection plate, respectively. For the metering groove 54 for dripping the detection plate, a one-way valve is installed on its regulating plate 62 to prevent the solution from flowing back; and the regulating plate 62 of the other metering groove 54 is provided with a through hole 64 to facilitate the free outflow of the solution.

[0062] When it is necessary to drip a sample onto the test plate, the driving motor 56 drives the rotating shaft 52 to rotate, so that the metering groove 54 equipped with a one-way valve is aligned with the liquid outlet pipe 41. At this time, the magnet 1 71 in the pressure piece 7 interacts with the magnet 2 72 on the metering box 51 to generate a repulsive force, and the adjustment plate 62 connected by the elastic rope 81 is pushed to the bottom, increasing the pressure in the metering groove 54, so that the sample solution can be smoothly dripped onto the test plate through the capillary. After the dripping is completed, the adjustment plate 62 is reset under the action of the elastic rope 81;

[0063] For test tube dripping, the rotating shaft 52 continues to rotate so that the other metering groove 54 is aligned with the liquid outlet tube 41, and the solution flows directly into the test tube under the action of gravity. The dripping amount can be controlled by setting the capacity of the metering groove 54;

[0064] During the dripping process, if the dripping tool needs to be replaced, the old dripping tool can be removed by the removal plate 94 in the replacement part 9, and a new dripping tool can be taken from the mounting frame 95 for installation;

[0065] During the entire working process, the cleaning liquid in the cleaning liquid tank 12 can be used to clean the transfer box 13, the metering box 51 and the dripping tool and other components to ensure the hygiene of the device and the accuracy of subsequent experiments. The waste box 93 is used to collect discarded solutions and dripping tools for unified treatment.

[0066] Example 2

[0068] Different from Example 1, a plurality of mounting grooves 14 are provided on the fixed plate 31, and a waste tray 1 15 is provided in each of the plurality of mounting grooves 14. A waste tray 2 16 is provided on the top of the transfer box 13. Through the provision of the waste tray 15, when the corresponding liquid is added into the sample box 11 and the cleaning liquid box 12, the solution splashed to the outside can be temporarily stored to avoid splashing in the main body 1 and affecting the subsequent dripping work. Through the provision of the waste tray 2 16, when the corresponding liquid is added into the transfer box 13, the solution splashed to the outside can be temporarily stored to avoid splashing in the main body 1 and affecting the subsequent dripping work.
