Abstract

1293651 Surgical infusion &c KOMBINAT MEDIZIN-UND LABORTECHNIK VEB 13 Feb 1970 7144/71 Heading A5R [Also in Division F2] A self-closing valve for use in medical liquid infusion and transfusion sets has a plastics flexible wall chamber 3 in which liquid flows from an inlet 1 to an outlet 4 and a ball 7 which is magnetically attracted to the outlet to close the latter when the level in the chamber slopes below a predetermined point. The bottom of the bag and outlet may be formed as a permanent magnet or an annular permanent magnet 15 may be removably mounted about the outlet. The ball may be hollow and of ferromagnetic material or may be hollow and of plastics material and contain a smaller ball 9 of ferromagnetic material. Boundary plates 6 are disposed below the inlet. The balls may be permanent magnets and the bottom of the bag and outlet of ferromagnetic material.
