Pressure infusion device.

摘要

A pressure infusion device for medical applications for applying pressure to a sealed bag of liquid (13), such as an I.V. bag, in which the pressure gauge (40) is fastened directly in the pressure applying bag (12) which presses against the I.V. bag. The gauge has a movable plunger (46) which moves outwardly from the bag by an amount depending upon the pressure within the bag. The pressure infusion arrangement is designed to be relatively inexpensive so that it can be discarded after being used. There are two forms, one in which the I.V. bag is held against the pressure applying bag by a mesh (11) which is secured to a fabric to form a pocket for the I.V. bag and the pressure applying bag. In the other form, the mesh (66) is secured directly to the edge of the pressure applying bag.
