Description

An oncology drainage device

technical field

The utility model relates to the technical field of medical devices, in particular to a drainage device for oncology departments.

Background technique

Drains are often used in the treatment of tumors. The traditional drainage device has the disadvantages of high cost and passive excretion, which cannot be well applied to clinical medical treatment. The traditional method is to use a rubber hose connected with a standard puncture needle, and use a syringe connected to it. The fluid in the tumor is drained. In the specific operation, the air in the syringe is first discharged, and then the syringe is connected to the rubber hose to pump the tumor effusion into the syringe. This process needs to be repeated until all the tumor effusion is pumped out. Use a syringe, often use a syringe to drain the fluid in the chest cavity through the drainage tube, which is very inefficient. This is not only time-consuming and laborious, but also increases the pain of the patient, and it is easy to cause cross-infection. The patient's effusion is detected, and after the extraction is completed, the patient often needs to be injected. The traditional method is to puncture the patient again, which increases the patient's pain and increases the labor intensity of the medical staff.
