Sedimentation bottle

Abstract

The invention relates to a hydrothorax and ascites sedimentation bottle. The bottle comprises a storage part for accommodating hydrothorax and ascites, the storage part is provided with an internal cavity for accommodating hydrothorax and ascites, a liquid inlet for loading hydrothorax and ascites and a sealing piece for detachably sealing the liquid inlet are arranged at the upper part of the storage part, the bottom of the storage part is provided with a sample discharge port for discharging target cells and a control piece for controlling the sample discharge port to be opened / closed, a liquid outlet for discharging supernatant and an adjusting part for controlling the opening / closing of the liquid outlet are arranged on the side surface of the lower part of the storage part, the liquidinlet, and the sample discharge port and the liquid outlet are respectively communicated with the internal cavity. The sedimentation bottle is simple and compact in structure, facilitates collection,storage and transfer of hydrothorax and ascites, can conveniently and safely treat supernatant while fully retaining cell suspension and / or precipitate, and prevents the biosafety problem caused by random discharge.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pleural and ascites sedimentation bottle. Background technique [0002] Pleural and ascites examination is clinically used to check the nature of thoracic ascites, so as to determine the cause and etiology of ascites formation, and play a guiding role in the treatment of clinical diseases. There are many causes, such as cardiovascular disease, liver disease, peritoneal disease, kidney disease, nutritional disorder, malignant tumor, peritoneal metastasis, ovarian tumor, connective tissue disease and so on. Excessive pleural effusion becomes pleural ascites, which can be divided into exudate and exudate according to its nature. [0003] In clinical practice, it is usually necessary to collect the patient's pleural and ascites fluid and send it for cytopathological examination. However, there is a lack of special containers for collecting and storing pleural and ascites f...

Problems solved by technology

[0003] In clinical practice, it is usually necessary to collect the patient's pleural effusion and submit it for cytopathological examination. However, there is a lack of containers specially used for collecting and storing pleural effusion in the prior art, resulting in a variety of existing pleural effusion collection containers, some Use used infusion glass bottles to collect pleural and ascites fluid, some use mineral water bottles to collect pleural and ascites fluid, and some use cups and other containers to collect pleural and ascites fluid; in addition to tumor cells, there may be a variety of germs, viruses and microorganisms in the pleural and ascites fluid. The collection of pleural and ascites in such a container not only has biological safety hazards, but also the container cannot be sterile, and the cells sent for inspection are prone to degeneration, which affects subsequent detection and diagnosis; cells) for cytological testing, and the existing container is used to collect pleural effusion. When taking the sediment in the container, it is necessary to pour over the supernatant in the container repeatedly. In this process, the sediment that was originally precipitated ( That is, the target cells) are raised while pouring, mixed with the supernatant, and finally poured out, losing important cell components, seriously affecting subsequent detection and diagnosis; in addition, the container in the prior art, from the collected The supernatant separated from the pleural and ascites is usually directly poured out. Since the supernatant must still contain the patient’s cells and other components, using this method to treat the supernatant will inevitably have biological safety problems, and now In the existing technology, it is also necessary to provide any effective technical means to solve this problem
