A bronchoalveolar lavage fluid sample collector

Abstract

The invention provides a bronchoalveolar lavage fluid sample collector, comprising a liquid collecting bottle, a first pipeline, a second pipeline, a first buckle cap and a second buckle cap; there are multiple liquid collecting bottles, each liquid collecting The bottles are all installed on the bottom of the first buckle cover through the detachable sealing of the bottle mouth; the first pipeline includes a main pipeline and multiple branch pipelines, and the main pipeline is connected with multiple branch pipelines; the first buckle cover is set There are the same number of first through holes and one second through hole as the number of liquid collection bottles; each branch pipeline is connected to a first through hole, and the second button cap is snugly connected with the first button cap, and the two can be opposite movement; the second button cover is provided with a third through hole, when the second button cover and the first button cover produce relative movement, the third through hole can communicate with each second through hole; one end of the second pipeline Connect with the third via. The device can realize the collection of multi-tube bronchoalveolar lavage fluid samples at one time without changing tubes, has high safety and is easy to operate.

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
