Problems solved by technology
[0003] In the prior art, the extraction of effusion is mostly realized by drainage device, that is, the extraction of effusion is realized by using the negative pressure in the drainage device. However, because the amount of effusion in the patient cannot be judged intuitively, the existing drainage device It is impossible to stop in time after the effusion is completely pumped out, and it is easy to pump out the air in the patient's body, which will cause discomfort to the patient and increase the risk of the drainage process

The invention provides a drainage device for medical oncology, and belongs to the technical field of drainage devices. The device comprises a storage part, a liquid inlet part, an expansion part, an elastic stretching part, an exhaust part, a suction part and a reset part, wherein the liquid inlet part is arranged on one side of the storage part. In the embodiment of the invention, the exhaust part, the expansion part, the air inlet part and the elastic stretching piece are arranged, so that the expansion part can move towards the middle part of the liquid inlet part when the suction part is used for extracting the accumulated liquid, and the accumulated liquid can flow into the storage part from a gap between the expansion part and the liquid inlet part; after effusion extraction is completed, the elastic stretching piece can pull the expansion part to the inner wall of the liquid inlet part and extrude and plug the exhaust part; air on one side of the suction part enters the expansion part from the air inlet part to drive the expansion part to swell, so that an inner cavity of the liquid inlet part is blocked, and air in the body of a patient is prevented from being pumped out; therefore, the discomfort of the patient is eliminated, and the safety in the hydrops extraction process is improved.
Description
technical field [0001] The invention belongs to the technical field of drainage devices, in particular to a drainage device for medical oncology. Background technique [0002] At present, most tumor patients have effusions in their bodies. Therefore, it is necessary to regularly extract the effusions in the patients' bodies to alleviate the pain of the patients. [0003] In the prior art, the extraction of effusion is mostly realized by drainage device, that is, the extraction of effusion is realized by using the negative pressure in the drainage device. However, because the amount of effusion in the patient cannot be judged intuitively, the existing drainage device It is impossible to stop in time after the effusion is completely pumped out, and the air in the patient's body is easily pumped out together, which causes the patient's discomfort and increases the risk in the drainage process. Contents of the invention [0004] In view of the above-mentioned deficiencies in ...
