Description

Tumour hydrops draw-out device

Technical Field

The utility model relates to the field of medical technology, specifically a tumour hydrops draw-out device.

Background

Tumor tissue differs from normal tissue from which it originates to a different extent, both in cell morphology and tissue structure, and this difference is called heterogeneity. The heterogeneity is the morphological manifestation of abnormal differentiation of tumors. Small heterogeneity, indicating high degree of differentiation, large heterogeneity, indicating low degree of differentiation. The difference in size of this abnormal shape is the main histological basis for diagnosing tumors and determining their benign and malignant properties. The heterogeneity of benign tumor cells is not obvious and is generally similar to the tissue from which they originate. Malignant tumors often have significant heterogeneity.

The traditional method for extracting the tumor effusion is to use a rubber hose connected with a puncture needle, discharge the effusion in the thoracic cavity and the abdominal cavity through an injector connected with the rubber hose, repeatedly extract the effusion by puncturing, not only increase the pain of a patient, but also easily cause cross infection, in addition, when extracting the effusion, the effusion extraction flow rate is not easy to be controlled, especially the effusion extraction speed is too fast, multiple complications are easily caused, the use is not flexible, and only simple effusion extraction is realized, and time and labor are wasted.
