Description

A multi-purpose sputum sample processing device and method thereof

technical field

The invention belongs to the field of medical technology, and specifically relates to a multipurpose sputum sample processing device and a method thereof.

Background technique

Sputum specimen is a common body fluid specimen in clinical examination, which is used for cell or bacteriological examination, especially in tubercle bacillus examination items. There are deficiencies in the collection and testing of sputum samples. For example, when collecting, the traditional method is to use an ordinary cup to let the patient spit inward. It will also generate airflow that makes people uncomfortable; at the same time, some sample cups need to pre-store the solution, and it is necessary to prevent the solution from splashing at this time; Acid bacillus test, Mycobacterium tuberculosis culture and drug susceptibility test, Mycobacterium tuberculosis molecular biology test, etc. Due to the difficulty in collecting sputum samples, there are still differences between different samples from the same person. Due to the viscous nature of sputum samples and the possible infectivity of sputum samples, it is very inconvenient to use the same sputum sample separately. With the help of a special sputum sample collection device and different sputum sample processing methods, the present invention can safely and effectively meet the requirements of different tests on the same sample, which is very meaningful in practical work.
