Effusion extraction device for oncology department

Abstract

The invention belongs to the technical field of medical apparatuses and instruments and relates to an effusion extraction device for an oncology department. The effusion extraction device comprises abody, an effusion box is arranged on the lower side of the body, a fixing frame is arranged on the rear side of the body, and a slide piston is arranged in a negative suction pipe which is arranged inthe body. An exhaust pipe is arranged on the lower side of the negative suction pipe, a pressure stabilizing tank is arranged on the right side of a negative suction tank which is arranged on the right side of the negative suction pipe, and a gas-liquid separator is arranged on the right side of a gas suction pipe which is arranged on the right side of the pressure stabilizing tank. An effusion buffer box is arranged on the lower side of a guide pipe which is arranged on the lower side of the gas-liquid separator, a drain pipe is arranged on the lower side of the effusion buffer box and provided with a drain control valve, and a branch guide pipe is arranged on the lower side of a drain seal adaptor which is arranged on the lower side of the drain control valve. The effusion extraction device is simple in structure, convenient to use, capable of continuously extracting effusion and preventing effusion from flowing back and safe and hygienic in operation, operating steps are reduced, and operating efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a fluid extraction device for oncology departments. Background technique [0002] In clinical oncology, it is often encountered that there is pleural or peritoneal effusion, which requires drainage of intracavitary effusion. The traditional way of effusion drainage is to use a large-sized syringe to connect a puncture needle with a rubber tube to extract it. , but the drainage efficiency of this extraction method is low. There is also a special effusion discharge device in the prior art, which replaces the extraction function of the syringe with an air bag. When the air bag is compressed, although it is difficult for unclean gas to enter the thorax and abdominal cavity, it is easy for the effusion in the needle tube to flow back to the thoracic or abdominal cavity. Simultaneously when it is in use, it needs reciprocating extrusion, and the continuity of work is not high,...

There is also a special effusion discharge device in the prior art, which replaces the extraction function of the syringe with an air bag. When the air bag is compressed, although it is difficult for unclean gas to enter the thorax and abdominal cavity, it is easy for the effusion in the needle tube to flow back to the thoracic or abdominal cavity. At the same time, when it is used, reciprocating extrusion is required, and the continuity of work is not high, which further reduces work efficiency.
