摘要

A hydrophilic filter to remove solid impurities in the liquid which is located between the space in the vertical direction of the inside of the filter housing, is flowed, the filter device of the present invention, the gas discharge holes of at least one provided in the filter housing After Before positioned corresponding to and passes through the hydrophilic filter, or passed through the hydrophilic filter, at least one for discharging the gas in the liquid or is the inlet in the before and after passing through the hydrophilic filter which is provided with a blocking member for blocking the hydrophobic filter Tsu, gas in the liquid that has passed through the hydrophilic filter to be flowed to the outlet pipe, so as to block the outlet pipe inside the filter housing, passage is formed in the longitudinal direction to the center, including a blocking member flowing liquid is introduced into the outflow pipe through the passage. In accordance with the present invention, may be introduced into the extension tube to the air of the drug inside is connected to the filter device and effectively removes impurities such as solid particles and the air contained in a liquid such as a drug no, when secured to maximize the surface area of ​​the hydrophilic filter to remove solid particles such as glass fragments, drugs to pass through, there is an advantage in that the flow rate is to avoid late.
