A kind of automatic sputum liquefaction instrument and sputum liquefaction method

Abstract

The invention discloses an automatic sputum liquefying instrument and a sputum liquefying method thereof. According to the automatic sputum liquefying instrument and the sputum liquefying method thereof, in the using process, a moving arm and a mechanical arm are arranged, the moving arm is used for moving a pipette, the mechanical arm moves up and down to pump liquid, discharge the liquid and blowing and mixing the liquid uniformly, automatic sputum liquefying, sputum-culture automatic sample adding and automatic sputum liquidation liquid sub-packaging are achieved, the automatic sputum liquefying instrument can treat sixteen sputum samples within 30 min, working efficiency is improved greatly, and the instrument has the advantages that automatic operation and flux treatment are achieved, operation is easy, use is convenient, and cross contamination between the samples is avoided; direct contact can be avoided, so that the probability of personnel infection and cross-contamination of the samples is reduced, and sputum is treated fast, economically and easily. The urgent basic requirement of a clinical testing mechanism is met. The instrument is applicable to the field of medical instruments.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an automatic sputum liquefaction instrument and a sputum liquefaction method thereof. Background technique [0002] At present, with the deepening of mycobacterium tuberculosis diagnosis and detection technology and theoretical research, sample preparation has become a bottleneck restricting its development. Due to the particularity of sputum, the culture and nucleic acid detection of Mycobacterium tuberculosis in sputum must undergo liquefaction treatment. In the traditional detection of Mycobacterium tuberculosis, manual operation has low detection efficiency, long operation time, sample cross-contamination, Insufficiencies such as uneven sample processing not only require a lot of manpower, material resources, and financial resources, but also the test results are unstable, which cannot meet the increasing demand for patient samples and testing, greatly reducing the efficien...

Due to the particularity of sputum, the culture and nucleic acid detection of Mycobacterium tuberculosis in sputum must undergo liquefaction treatment. In the traditional detection of Mycobacterium tuberculosis, manual operation has low detection efficiency, long operation time, sample cross-contamination, Insufficiencies such as uneven sample processing not only require a lot of manpower, material resources, and financial resources, but also the test results are unstable, which cannot meet the increasing demand for patient samples and testing, greatly reducing the efficiency of tuberculosis diagnosis, and medical staff must directly contact samples, which may cause infection and personal injury
