Abstract

1481427 Measuring chambers for intravenous set UNITED STATES SURGICAL CORP 12 Aug 1974 [21 Aug 1973] 35492/74 Heading A5R A flexible and transparent polyvinyl chloride measuring chamber 20 for use in an intravenous set comprises a flexible polyvinyl chloride inlet tube 16 for the parenteral fluid, a connecting member 24 of a rigid plastics material e.g. styrene-acrylonitrile for providing a fluid passageway 58 between the chamber and a double flow meter 22, and a passageway 62 for a medicament to be mixed with the parenteral. fluid in the chamber, the lower end of the passageway 62 being closed by a rubber cap 66. The lower end of the passageway 58 is sized so that drops of a predetermined size are formed in the drip chamber 60 of the double flowmeter. In another embodiment (Fig. 3 not shown) the chamber, made of a rigid plastics material, is cylindrical and is provided with upper and lower end caps, the upper end cap being connected to the flexible inlet tube 16 and provided with an air outlet tube 102 having an air-permeable membrane 103. The connecting member having a liquid-permeable filter downstream of the measuring chamber is attached to the lower end cap. An intravenous set comprises the measuring chamber arranged downstream of a pierrer (12) connected to a parenteral fluid supply bottle and upstream of the double flow meter 22, the connecting member 24, compression clamps, and an intravenous needle adapted.
