Problems solved by technology
[0002] The existing method of adding samples to the identification plate is to use mechanical movement and electric piston to add the bacterial suspension drop by drop to the identification plate. The biggest disadvantage of this method is that the sample addition speed is slow, and only one suspension can be added at a time Bacterial liquid, the efficiency is very low, and the structure of mechanical moving parts is complex and costly, which is inconvenient to maintain. In addition, the bacterial suspension is easy to leak during titration, which is not safe enough

The invention discloses a negative pressure sample feeding instrument and a negative pressure sample feeding method for a biochemical analysis and identification plate. The negative pressure sample feeding instrument comprises a vacuum chamber, a storage rack, and an identification plate and a liquid bottle arranged on the storage rack, wherein the identification plate is communicated with bacterium suspension in the liquid bottle by a slime tube; the vacuum chamber comprises a vacuum pump, a gas inlet valve, a pressure sensor and a chamber for placing the storage rack; the vacuum pump and the gas inlet valve are communicated with the chamber by a pipeline, and the pressure sensor is used for measuring gas pressure in the chamber. According to the sample feeding instrument and method, negative pressure can be formed in a cultivation hole in the identification plate by the vacuum chamber, partial bacterium suspension in the liquid bottle can be sucked into the identification plate by utilizing the negative pressure, the work of feeding bacterium suspension of different types for multiple identification plates can be completed by using just tens of seconds, the sample feeding efficiency is high and the operation is safe.
Description
technical field [0001] The invention relates to the technical field of adding samples to an identification plate, in particular to a negative pressure sampling instrument and method for an identification plate for biochemical analysis. Background technique [0002] The existing method of adding samples to the identification plate is to use mechanical movement and electric piston to add the bacterial suspension drop by drop to the identification plate. The biggest disadvantage of this method is that the sample addition speed is slow, and only one suspension can be added at a time Bacterial liquid, the efficiency is very low, and the structure of mechanical moving parts is complex and costly, which is inconvenient to maintain. In addition, the bacterial suspension is easy to leak during titration, which is not safe enough. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a biochemical an...
