Abstract

1398628 Intravenous apparatus BESTNU ENG PTY LTD 13 Sept 1972 [28 Sept 1971] 42419/72 Heading A5R [Also in Divisions Fl and F2] Apparatus for applying external pressure to a pliant bag 56 containing a liquid for administration to a patient comprises two pads having mutually confronting spaced-apart pressure-applying faces and loading means operable to cause relative mutual approach of said faces so applying pressure to the bag which is positioned between the two said faces. The two pads are constituted one by the rear wall 28 and the inflatable bag 29 which extends the full width and height of the rear wall and the other by a plate 52 adhered to a door panel 54 so that its side and bottom edges form steps 55 relative to the rear face of the door 54. Inflating the bag 29 causes the pressure--applying face 60 to move towards the pressure-applying face of the plate 52 and the steps 55 ensure that the pliant bag 56 is never completely flattened whereby any gas in the bag stays in the bag and is not administered to the patient. The pliant bag 56 is supported between these two faces by a pin 57 the outlet of the bag 58 being lowermost. The inflatable bag 29 has an inlet/outlet pipe 30, the air for inflating the bag being supplied by a manually operable air pump 10, via the pipe 41 and a valve (11) (Figures 3, 4 and 5, not shown). This valve, operated by the switch 50 in one position allows air to escape from the bag 29 so deflating it, in a second position closes the system to the atmosphere for allowing inflation of the bag and has a third position for allowing bleed escaping of air from the bag during inflation so permitting fine adjustment. The pressure of the air in the bag is shown on the dial portion 14 of a pressure guage 12 which is connected via the valve (11) to the inflatable bag. When the inflatable bag 29 is fully inflated and the two sides of the pliant bag 56 are pressed together there is still sufficient volume in the pliant bag to contain any gas that may have been included with the liquid due to ducts in the bag formed around the edges of the plate 52 which have not been compressed. There is a lateral duct 62 extending along the base of the pliant bag and a vertical duct extending the full height of the pliant bag, this ensures that any gas in the bag may proceed without obstruction to'the gas space above the liquid surface of the bag. The apparatus is housed in a small cabinet having an upper compartment 8 housing the valve (11), the pump 10 and the pressure guage 12 and a lower compartment 9 housing the two pads and the support for the pliant bag and having a door 21 on the front of this lower compartment for easy insertion of the pliant bags. A bracket 15 at the side of the cabinet provides for mounting the apparatus on a bed post (20) etc.
