Description

Clinical laboratory uses sputum sampler

Technical Field

The utility model relates to the technical field of medical equipment, specifically a clinical laboratory uses sputum sampler.

Background

Sputum is the secretion of the alveoli, bronchi and trachea. Healthy people have little sputum. Under normal conditions, the bronchial mucosa gland box goblet cells can secrete a small amount of mucus, so that the respiratory mucosa is kept moist. In pathological conditions, the mucous membrane is congested and edematous after the respiratory tract mucous membrane and the pulmonary alveoli are stimulated, serous fluid is exuded, and the mucous secretion is increased. Various cells (red blood cells, white blood cells, phagocytes, etc.), exudates such as fibrin, etc., are mixed with mucus, inhaled dust, some tissue necroses, etc. to form sputum. The composition of sputum is complex and consists of 95% moisture and 5% dust, protein, etc. The sputum examination has certain value for diagnosis, observation of curative effect and prognosis of respiratory system diseases such as pulmonary tuberculosis, lung fluke, lung tumor, bronchial asthma, chronic bronchitis, bronchiectasis and the like.

Sputum detection data is one of the important bases for clinicians to judge the health status of patients. Generally, the sputum spitted out by a patient is contained by a vessel, marked with a code and tested by a clinical laboratory staff to obtain a report. Chinese patent (publication No. CN205404198U) discloses a sputum sampler for clinical laboratory, which comprises a blowing nozzle, filter cotton, a separation tube, a bracket, a detection part, a control part and an air exhaust part, wherein the blowing nozzle is fixed at one end of the separation tube, the filter cotton is located at the round hole of the inlet of the blowing nozzle, the bracket is fixed at the lower side of the separation tube, the detection part is fixed at the lower side of one end of the bracket, the control part is fixed with the bracket, the air exhaust part is connected with the separation tube, although the device can realize rapid sampling of sputum to a certain extent, the device can not adjust the length forwards and backwards in the actual sampling process, so that the application range of the whole device is greatly reduced, and therefore, further improvement is needed.
