Description

Technical Field

[0001] This utility model relates to the field of medical testing equipment technology, specifically a mixing device based on Mycobacterium tuberculosis drug sensitivity detection. Background Technology

[0002] Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis, which seriously threatens human health. In the treatment of tuberculosis, it is crucial to accurately detect the sensitivity of Mycobacterium tuberculosis to various anti-tuberculosis drugs, as this directly affects the formulation of treatment plans and treatment outcomes.

[0003] Currently, traditional drug sensitivity testing methods, such as culture methods (solid / liquid), require long cycles and need to be combined with phenotypic drug sensitivity tests. This process is time-consuming, involves a lot of manual intervention, is cumbersome, and heavily relies on professionals. This not only delays the optimal treatment time for patients but may also introduce uncontrollable factors due to manual operation during the culture process, potentially leading to worsening of the condition and increased detection errors. This puts great pressure on the high accuracy requirements of clinical testing. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a mixing device for Mycobacterium tuberculosis drug susceptibility testing. This device has the advantages of accelerating the efficient mixing of samples and diluents, reducing the testing cycle for Mycobacterium tuberculosis drug susceptibility, and achieving full automation by connecting to automated equipment, thereby reducing manual operation. It effectively solves the problems mentioned in the background technology.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mixing device based on tuberculosis drug sensitivity detection, comprising a storage tank, a sealing mechanism above the storage tank, a storage mechanism inside the storage tank, the storage mechanism comprising a motor, the bottom of the motor being fixedly installed in the middle of the bottom inside the storage tank, a rotating shaft being fixedly connected to the top of the motor, a placement tray being fixedly connected to the top of the rotating shaft, and a plurality of placement cylinders being fixedly connected to the upper surface of the placement tray.

[0008] Preferably, a number of spring tubes are fixedly connected to the inner wall of the placement cylinder.

[0009] Preferably, a clamp is fixedly connected to the other end of the spring tube.

[0010] A number of spring tubes are evenly and vertically connected at one end to the inner wall of the placement cylinder. The clamping plate can move elastically through the spring tubes to hold the sample.

[0011] Preferably, the sealing mechanism includes a threaded groove formed on the upper surface of the storage tank.

[0012] Preferably, a threaded tube is provided above the threaded groove.

[0013] Preferably, a sealing cap is fixedly connected to the upper surface of the threaded tube, and a knob is fixedly connected to the middle of the upper surface of the sealing cap.

[0014] The threaded groove fits into the upper surface of the storage tank, and the threaded tube can be screwed into the inside of the threaded groove. The sealing cap can be threadedly connected to the storage tank through the threaded tube at the bottom, making it convenient for operators to disassemble and assemble. The knob makes it easy for operators to turn the sealing cap.

[0015] Compared with the prior art, this utility model provides a mixing device based on Mycobacterium tuberculosis drug susceptibility detection, which has the following beneficial effects:

[0016] This invention utilizes a motor installed at the bottom of the storage tank. The motor drives the placement tray to rotate via a top shaft, and the bottom motor shaft drives the placement tray to rotate. The stable mechanical power output enables efficient mixing of the sample and diluent as they rotate. The centrifugal force and eddy current effect generated during rotation promote liquid stratification and accelerate uniform mixing, greatly reducing sample mixing time and thus shortening the cycle of tuberculosis drug sensitivity testing.

[0017] This invention utilizes a spring tube connected to the inner wall of a placement cylinder. The clamping plate can move elastically through the spring tube, and the clamping plate is displaced by the compression or stretching of the spring tube, automatically adjusting the clamping force to ensure that the sample is fixed. Furthermore, the elastic properties of the spring tube can match the differences in sample size, allowing for the replacement of different samples without changing the container or adjusting the structure, thus reducing manual intervention.
