FLODESREGLERINGSANORDNING FOR REGLERING AV VETSKEFLODE

摘要

The device possesses a supply chamber (10) having at least one inlet channel (8) and a filter chamber (11) communicating with the supply chamber (10) via a passage (14). An outlet chamber (17) is connected to the filter chamber (11). A first membrane (6) under tension is located in the supply chamber (10) and covers the passage (14) between the supply chamber (10) and the filter chamber (11) until the liquid pressure prevailing in the inlet channel (8) has reached a specified magnitude. The inlet channel (8) and the passage (14) open into the supply chamber (10) on the same side of the first membrane (6). The outlet chamber (17) houses a second membrane (7) which subdivides this chamber into two separate parts which are connected via a bypass channel (31). There are control devices (29) for adjusting the flow cross-section of the bypass channel (31). An outlet channel (30) is connected to that part of the outlet chamber (17) which lies downstream from the diversion channel (31). The second membrane (7) can be moved toward the outlet channel (30) and away from the latter in order to control the amount of liquid flowing through it as a function of the pressure differential prevailing between the two separate parts of the outlet chamber (30). The device permits precise control of liquids for intravenous administration.
