Technical Field

The invention relates to the technical field of medical instruments, in particular to a pleural effusion and ascites sedimentation bottle.

Background

The examination of ascites and thoracico-ascites is used clinically to examine the property of ascites and thus to determine the cause and etiology of ascites formation and to play an instructive role in the treatment of clinical diseases. The etiology of the disease is many, such as cardiovascular disease, liver disease, peritoneum disease, kidney disease, nutrition disorder malignant tumor peritoneal metastasis ovarian tumor, connective tissue disease, etc. Pleural effusion is formed in the course of disease and becomes pleural ascites, and the pleural effusion can be divided into effusion and effusion according to the nature.

In clinic, the pleuroperitoneal fluid of a patient is usually collected and examined for cytopathology examination, however, the prior art lacks a container specially used for collecting and storing pleuroposterior fluid, so that the prior pleuroposterior fluid collecting container is eight-door, the used transfusion glass bottle is used for collecting pleuroposterior fluid, the mineral water bottle is used for collecting pleuroposterior fluid, and the like are used for collecting pleuroposterior fluid; besides tumor cells, a plurality of pathogenic bacteria and virus microorganisms can be contained in the pleural effusion and the peritoneal fluid, and the pleural effusion and the peritoneal fluid are collected by adopting the container, so that not only is the potential biological safety hazard existed, but also the container can not achieve sterility, and the cells to be detected are easy to degenerate, thereby influencing the subsequent detection and diagnosis; after the specimen reaches a pathology department, standing is needed, sediments (namely target cells) are taken out for cytological detection, the existing container is adopted for collecting hydrothorax and ascites, when the sediments in the container are taken out, supernate in the container needs to be poured repeatedly, in the process, the sediments (namely the target cells) which are originally precipitated are lifted while being poured, are mixed with the supernate and are finally poured out, important cell components are lost, and subsequent detection and diagnosis are seriously influenced; in addition, the supernatant separated from the collected pleuroperitoneal water in the container of the prior art is usually directly poured off, and since the supernatant necessarily contains the cells and other components of the patient, the supernatant treated in such a way inevitably has biological safety problems, and the prior art also provides any effective technical means for solving the problems.

3. after the sedimentation is finished, the recovery part 301 is rotated reversely relative to the bottle body 101 (i.e. in the opposite direction to the rotation direction in the initial screwing process), and when the second communication hole 303 is inevitably rotated to the position corresponding to the communication port 405 within one turn, the two are communicated, so that the bottle body 101 can be communicated with the recovery part 301, and the supernatant in the bottle body 101 can automatically enter the storage cavity 302 of the recovery part 301 under the action of gravity;

4. after the supernatant of the bottle body 101 completely enters the recovery part 301, the recovery part 301 is continuously rotated, so that the second communication hole 303 and the communication port 405 are dislocated, the purpose of sealing the storage cavity 302 is achieved, the liquid in the storage cavity is prevented from flowing out, the supernatant is prevented from being randomly discharged, and the biological safety problem is effectively solved;

5. the recycling part 301 continues to rotate until the second stopper 305 contacts the first stopper 406, and then the recycling part 301 continues to rotate, at this time, the recycling part 301 can drive the annular connector 401 relative to the bottle body 101, so that the necking part 104, the annular connector 401 and the recycling part 301 can be separated from the bottle body 101 as a whole, the precipitate can be taken away from the upper part of the necking part 104 conveniently, or the precipitate can be discharged from a sample discharge port at the lower part of the necking part 104, and the used necking part 104, the annular connector 401, the recycling part 301 and the supernatant sealed in the recycling part 301 can be used as a whole to perform subsequent waste treatment, thereby being very environment-friendly and effectively avoiding the biological safety problem caused by random discharge.

It is understood that the recycling portion 301 has various shapes and configurations, such as a ring shape, etc., and as shown in fig. 8, the base 109 can also be directly disposed at the lower end of the recycling portion 301, which is not described in detail herein.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
