Fluid storage, filtration and gas separation apparatus, and hematoma evacuator based on the fluid storage, filtration and gas separation apparatus

摘要

A fluid-storing, filtering, and gas-discharging apparatus(2) comprising a fluid holder(21), a gas detector(23), and a filter(22), The fluid holder(21) has a protruding apex structure and comprises a fluid inlet and a fluid outlet. A gas-discharging pipe in communication with the outside is arranged on the protruding apex of the fluid holder(21). The gas detector(23) is arranged on the gas-discharging pipe. The filter(22) is fixed within the fluid holder(21) and is connected to the fluid outlet. The fluid-storing, filtering, and gas-discharging apparatus(2) uses the fluid holder(21) and the filter(22) to implement the storage and filtration of a working fluid, while at the same time, the fluid holder (21) having the protruding apex structure ensures complete discharging of gases mixed in the working fluid, thus achieving the goals of fluid storage, filtration, and gas discharge, and providing great reliability.
