Description

Technical Field

[0001] The utility model relates to the technical field of analyzer sample addition, in particular to an integrated device for air incubation, high-speed mechanical vibration mixing and detection of a biochemical analyzer. Background Technique

[0002] A biochemical analyzer is an instrument that measures a specific chemical component in body fluids using the principle of photoelectric colorimetry. Biochemical analyzers can be classified into dry biochemical analyzers and wet biochemical analyzers according to their functions, into low-speed biochemical analyzers, medium-speed biochemical analyzers and high-speed biochemical analyzers according to their speeds, and into fully automatic biochemical analyzers and semi-automatic biochemical analyzers according to their operation modes. The moving sample addition method is an important accessory on the biochemical analyzer, used to accurately position and sample reagents, and in order to ensure the accuracy of the experiment, the sampling needle needs to reach the specified reagent and sample holes through high-precision positioning every time on the biochemical analyzer.

[0003] Common biochemical analyzers are usually composed of mechanisms such as a sampler, a sampling device, a reaction cell, a thermostat, a detector, a microprocessor and a function monitor. The sampling device takes samples from the sampler, dilutes them and transports them to the reaction cell through pipelines. The thermostat provides a constant temperature environment for the chemical reaction. The detector is responsible for measuring the optical or electrical signals generated by the chemical reaction and converting them into quantifiable data. The microprocessor controls all the actions and functions of the instrument, and the function monitor is also responsible for monitoring the performance indicators of the instrument to ensure that the instrument is in the best working state.

[0004] Most traditional biochemical analyzers use disk-type incubation, separate mixing and separate detection. Mixing mainly relies on a 42-step motor to drive a stirring needle, incubation is basically achieved by water bath constant temperature treatment, and the detection is a fixed detection method. At present, the mixing method relying on the stirring needle brings a very big hidden danger to the cross-contamination of the experiment and has a great impact on the experimental results; for the water bath constant temperature of incubation, due to the need to add protective agents and antibacterial agents, it is also necessary to change water regularly, which greatly increases the material cost and labor cost. If the incubation water system is not processed in time and bacterial mildew occurs, it will greatly affect the experimental results; for the fixed detection, due to the fixed installation and inflexibility, it cannot handle special situations. Therefore, an integrated device for air incubation, high-speed mechanical vibration mixing and detection of a biochemical analyzer is proposed. Content of the Utility Model
