AI Technical Summary
Technical Problem
During sample pretreatment, it is difficult to accurately control the amount of mixed solution, which affects the test results.
Method used
A quantitative detection consumable is designed. By setting a piston structure and a limit structure in the sample tube, the piston structure is used to pierce the sealing membrane to allow the treatment liquid to flow quantitatively into the reaction chamber, eliminating the container replacement step and achieving precise transfer of the mixed solution.
Benefits of technology
The quantitative transfer of the mixed solution is achieved, the operation process is simplified, the excessive solution is prevented from entering the reaction chamber, and the accuracy of the detection results is improved.

Abstract
The utility model provides a quantifiable detection consumable and detection equipment, and relates to the in vitro diagnostic technology, the quantifiable detection consumable comprises a sample tube with a cavity and a reaction tube communicated with the sample tube, the reaction tube is provided with a reaction cavity and a sealing film for sealing the reaction cavity; the piston structure is arranged in the cavity; a first limiting structure used for limiting the piston structure to the first position and a second limiting structure used for limiting the piston structure to the third position are further arranged on the inner wall of the sample tube, the piston structure pierces the sealing film when moving to the third position from the first position, and the treatment liquid quantitatively flows into the reaction cavity; the piston structure is used for puncturing the isolating membrane isolated between the cavity and the reaction cavity, so that the treatment liquid enters the reaction cavity, the step of container replacement is omitted, meanwhile, the piston structure is pushed to move by a preset stroke, it is ensured that the mixed solution quantitatively flows into the reaction cavity, and it is avoided that excessive mixed solution enters the reaction cavity, and the detection result is affected.
