The invention discloses a residual liquid recovery device and method and a pharmaceutical liquid mixing system. The residual liquid recovery device comprises a sterilizing filter, an exhaust pipe, a diaphragm valve and a glass sight glass. One end of the exhaust pipe is arranged on the top of the sterilizing filter, and the exhaust pipe is communicated with an inner cavity of the sterilizing filter. The diaphragm valve is arranged in the exhaust pipe and located above the top of the sterilizing filter. The glass sight glass is arranged on the exhaust pipe and located above the top of the sterilizing filter and on the upstream portion of the diaphragm valve. The pharmaceutical liquid mixing system comprises the residual liquid recovery device. The residual liquid recovery method comprises a deep purge recovery stage. Residual liquid in a front feed liquid pipeline of the filter can be effectively recovered, so that the yield of products is increased. The residual liquid recovery device and method are particularly suitable for the product production process with high added value, and economic benefits are greatly increased on the premise of not affecting product quality.
Description
technical field [0001] The invention relates to a residual liquid recovery device, a method and a pharmaceutical liquid preparation system. Background technique [0002] In the pharmaceutical liquid preparation system, hydrophilic liquid filters are usually used to reduce the microbial load of the liquid medicine or to perform sterilizing filtration. In view of the characteristics of the hydrophilic filter element, the gas needs to be higher than the filter element to pass through the filter. Take a certain brand of 0.22μm, PVDF filter element liquid filter as an example, the bubble point at 23°C is ≥3.45bar (wetted by air and water), that is to say, the air needs to be greater than 3.45bar to ensure the water pressure past. [0003] In the actual production of pharmaceutical liquid preparation, the feed liquid is transported from the liquid preparation tank through the sterilizing filter to the high-level filling tank through compressed air. Residue purge. After the feed...
