Sample harvester of bronchoalveolar lavage fluid

Abstract

The invention provides a sample harvester of bronchoalveolar lavage fluid, which comprises a fluid collecting bottle, a first pipeline, a second pipeline, a first buckling cover and a second bucklingcover; there are multiple liquid collecting bottles, and each liquid collecting bottle is detachably and hermetically mounted at the bottom of the first buckling cover through a bottle opening of theliquid collecting bottle; the first pipeline comprises a main pipeline and a plurality of branch pipelines, and the main pipeline is communicated with a plurality of branch pipelines; the first buckling cover is provided with first through holes and a second through hole, the number of the first through holes and the liquid collecting bottles are the same; each branch pipeline is connected with one first through hole, and the second buckling cover is connected with the first buckling cover, and the second buckling cover can move relatively to the first buckling cover; a third through hole is formed in the second buckling cover, and when the second buckling cover and the first buckling cover move relatively, the third through hole can be communicated with each second through hole; one end of the second pipeline is connected with the third through hole. The sample harvester can collect multi-tube bronchoalveolar lavage fluid samples in one time without replacing tubes, the safety is extremely high, and meanwhile the operation is easy and convenient.

Description

technical field [0001] The invention belongs to medical device technology, in particular to a bronchoalveolar lavage fluid sample collector. Background technique [0002] The standardized collection and inspection process of bronchoalveolar lavage fluid (BALF) is the prerequisite for obtaining correct microbiological and cytological results of BALF, but the results obtained through inappropriate operation methods can easily mislead clinical diagnosis and treatment. [0003] At present, for the collection of bronchoalveolar lavage fluid, there is no BALF collector used in conjunction with the bronchofiberscope. The ordinary sputum suction box generally includes a bottle body, a collection tube, a negative pressure suction tube, a sealing cover and a spare sealing cover. The negative pressure suction tube is connected to the negative pressure equipment, and the collection tube is connected to the suction port of the bronchoscope. When collecting specimens, the BALF sucked out...

Problems solved by technology

When collecting specimens, the BALF sucked out first may be mixed with non-lesional pathogenic bacteria, which will affect the test results. Therefore, the first tube is usually waste liquid. After the suction is full, turn off the negative pressure suction equipment, remove the first tube, and replace it. After a new collection tube, restart the negative pressure suction equipment, and then collect the second, third, and fourth tubes. Every time you change the tube, you need to turn off and restart the negative pressure equipment. Obviously, this operation process is very cumbersome. Increased operation time makes the bronchoscope stay in the body for too long, increases the stimulation of the patient's airway, and brings greater pain to the patient. In addition, frequent tube changes will increase the risk of specimen contamination. It is also very likely to cause the risk of aerosol spread infection, which will be greatly increased for highly contagious viruses such as the new coronavirus
