Abstract
The utility model relates to a lavage fluid collector, in particular to a bronchoavleolar lavage fluid collector and aims to overcome the inconvenience that lavage fluid collected by the existing bronchoavleolar lavage fluid collector needs to be filtered prior to detection. The upper end of a sleeve is sealed by a sealing plug, the sleeve is provided with a pulling plug on the lower portion, a piston is arranged at the upper end of the pulling plug, the piston slides on the inner wall of the sleeve, the lower end of a straw penetrates through the sealing plug to be disposed in the sleeve, the straw is provided with a filter and a push switch, the lower end of a negative pressure pipe penetrates through the sealing plug to be disposed in the sleeve, the upper end of the negative pressure pipe is connected with one end of a negative pressure bulb, the other end of the negative pressure bulb is connected with a one-way exhaust valve, the negative pressure pipe is connected with the one-way exhaust valve, and a sample pipe is inserted on the side wall of the sleeve and is located above the piston. The bronchoavleolar lavage fluid collector is used for collecting bronchoavleolar lavage fluid.
Description
Technical field
This utility model relates to a kind of irrigating solution catcher, is specifically related to a kind of bronchoalveolar lavage fluid catcher.
Background technology
Though sputum examination can be offered help to the diagnosis of respiratory tract disease, sensitive not and special and little to the help of disease location.A new technique that grows up on the branchofiberoscope basis in the bronchoalveolar lavage (bronchoalceolar lavage, BAL).BAL uses branchofiberoscope to carry out bronchoalveolar lavage, takes alveolar surface lining liquid to carry out the method that inflammation and immunocyte and solable matter check.Injecting a large amount of liquid of bronchus letter perfusion from a small amount of liquid of irrigation of bronchus, to carry out bronchoalveolar lavage different, utilize bronchoalveolar lavage fluid to carry out every check of the aspects such as cytology, microbiology, parasitology and immunology, some lower respiratory illnesses and diagnosis, disease observation and prognosis judgement have been opened up a new way.There was inconvenient problem with use in the ability sample detecting after irrigating solution after existing bronchoalveolar lavage fluid catcher is collected need to filter.
The utility model content
The purpose of this utility model is for could sample detecting after solving irrigating solution after existing bronchoalveolar lavage fluid catcher is collected and need to filtering, and has inconvenient problem with use, and then a kind of bronchoalveolar lavage fluid catcher is provided.
The technical solution of the utility model is: the bronchoalveolar lavage fluid catcher comprises pulling plug, sleeve pipe, piston, sealing-plug, filter, suction pipe, push switch, negative tube, negative pressure ball, breather cheek valve, unidirectional air outlet valve and probe tube, the upper end of sleeve pipe seals by sealing-plug, the bottom of sleeve pipe is provided with pulling plug, the upper end of pulling plug is provided with piston, piston slides at the inwall of sleeve pipe, the lower end of suction pipe is passed sealing-plug and is placed in the sleeve pipe, suction pipe is provided with filter and push switch, the lower end of negative tube is passed sealing-plug and is placed in the sleeve pipe, the upper end of negative tube is connected with an end of negative pressure ball, the other end of negative pressure ball is connected with unidirectional air outlet valve, be connected with breather cheek valve on the negative tube, probe tube is inserted on the sidewall of sleeve pipe, and probe tube is positioned at the top of piston.
This utility model compared with prior art has following effect: bronchoalveolar lavage fluid catcher of the present utility model directly filters irrigating solution by at suction pipe filter being set, irrigating solution after the collection can be directly used in sample detecting, and is easy to use.In addition, bronchoalveolar lavage fluid catcher of the present utility model can form negative pressure by the pull pulling plug and carry out the irrigating solution collection, also can form negative pressure by extrusion ball and carry out the irrigating solution collection, and occupation mode can be selected as required.Bronchoalveolar lavage fluid catcher of the present utility model also has simple in structure and advantage that be convenient to manufacture.
