Description

Technical Field

[0001] The present application relates to the technical field of specimen collectors, and more specifically, to a bronchoalveolar lavage fluid specimen collector. Background Art

[0002] Bronchoscopy is an important means of clinical diagnosis and treatment of respiratory diseases. It has been widely used in clinical work and has become an indispensable examination method. Bronchoalveolar lavage is one of the more commonly used techniques. This technology plays an important role in assisting the etiology of respiratory diseases. A very important step in the operation of this technology is to collect the recovered alveolar lavage fluid for laboratory examination. At present, we routinely use bronchoscope sputum collectors to collect alveolar lavage fluid in clinical work. The sputum collector bottle can use the negative pressure principle to suction sputum through a suction tube to achieve sputum specimen collection.

[0003] The existing public technology number CN210301074U proposes a bronchoscope sputum collector that is easy to disassemble and fix. The device avoids secondary contamination during the collection process, improves the accuracy of specimen inspection, and also solves the inconvenience in sampling airway secretions or alveolar lavage fluid in clinical medical procedures. It has excellent practicality and promotion value. However, when used, compared with the bronchoscope sputum collector in the literature, although it is easy to install and collect sputum, when it is necessary to collect multiple sputum samples, during the process of replacing the sputum collector bottle, the sputum remaining at the suction tube port is easy to overflow to the external environment or splash onto the surface of the new and old sputum collector bottles. In addition, when the sputum collector bottle that has been collected is discharged, the sampling efficiency is not high by opening the cap and using a dropper sampling method. In view of this, we propose a bronchoalveolar lavage fluid specimen collector. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] The purpose of the present application is to provide a bronchoalveolar lavage fluid specimen collector, which solves the technical problem that although the bronchoscope sputum collector in the comparative literature in the above-mentioned background technology is easy to install and collect sputum, when multiple sputum samples need to be collected, during the process of replacing the sputum collector bottle, the sputum remaining at the suction tube port is easy to overflow into the external environment or splash onto the surface of the new and old sputum collector bottles, and when the collected sputum collector bottle discharges the sample sputum, the sampling efficiency is not high by opening the cover and using a dropper sampling method, thereby realizing that the bottom cover and the upper cover at both ends of the collector bottle are respectively connected through the plug-in tube One and two stop valve tubes are plugged in and connected. The two stop valve tubes at the upper cover can be detachably connected to the suction tube and the sputum suction tube. A negative pressure state is formed in the collector bottle through the negative pressure device and the suction tube, so that the sputum suction tube collects sputum for processing. When sputum needs to be collected multiple times, the stop valve tube connected to the sputum suction tube is closed for processing, which can effectively prevent the sputum suction tube from dripping into the external environment, and the collector bottle can be directly disassembled and replaced with a new one. When extracting specimens, the stop valve tube at the bottom cover is opened, and the slide bar is manually pressed to slide along the collector bottle through the inner disk. The pressure of the collector bottle increases, forcing the sputum to be discharged quickly, thereby improving the efficiency of specimen extraction.
