Thoracic and abdominal cavity liquid negative pressure pumping device capable of accurately pumping amount

Abstract

The invention discloses a thoracic and abdominal cavity liquid negative pressure pumping device capable of accurately pumping the amount, which relates to the technical field of medical instruments, and solves the problems that the maximum volume of an existing needle cylinder is limited, the negative pressure manufacturing stroke is small, pleural effusion of a patient cannot be completely pumped, and the pain of the patient is increased. The thoracic and abdominal cavity liquid negative pressure pumping device capable of accurately pumping the amount comprises a negative pressure pumping cylinder, and a connecting cylinder which is inserted into the bottom of the mounting cylinder. When the device is used, the negative pressure generation assembly can be controlled by the control device to continuously generate negative pressure, the negative pressure generation period is not interrupted, effusion in the pleuroperitoneal cavity of a patient can be stably, efficiently and quantitatively extracted under any condition, extraction is rapid, pain of the patient during effusion extraction is relieved, and use is convenient.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more specifically relates to a negative pressure pumping device for thoracic and peritoneal fluid that can accurately pump volume. Background technique [0002] Pleural effusion is a common clinical symptom characterized by pathological fluid accumulation in the pleural cavity. When treating patients, it is necessary to insert a puncture needle into the patient's pleural effusion site to extract a certain amount of effusion for detection, so as to accurately detect Diagnose the actual condition of the patient and facilitate subsequent effective treatment of the patient. [0003] For example, in the patent with the application number: CN201510984815.2, a pleural cavity puncture flushing device is disclosed, which includes a wide adhesive tape, a dirt bucket, a lotion bottle, a drainage bag, and also includes a puncture sleeve with an external thread in the middle section, an adjustment...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a negative pressure pumping device for thoracic and peritoneal fluid that can accurately suck the amount, so as to solve the problem of suctioning through the syringe in most cases when the patient's pleural effusion is extracted for laboratory examination. The maximum volume of the syringe is limited, and the negative pressure stroke is relatively small. It is impossible to completely extract the pleural effusion of the patient. Multiple operations are often required, which increases the pain of the patient. Moreover, the negative pressure stroke of the syringe is small. It is not possible to accurately extract the amount of pleural effusion in the first extraction, the steps are cumbersome and cumbersome, and the practicability is not high.
