APPARATUS AND METHODS FOR MULTIPLE FLUID INFUSION
摘要:
We disclose apparatus and methods for delivering for patient infusion or other use two or more fluids either sequentially or simultaneously. The apparatus (100) has a fluid delivery compartment (101) containing a first infusion fluid (103), a flexible membrane (104), and an openable bag (150) containing a second infusion fluid (152). An attached gas reaction compartment (121) contains chemical reactants (123, 134) which, when combined, react to evolve gas (122). The gas (122) expands a gas expansion chamber (102) causing the membrane (104) to move into the fluid delivery compartment (101), displacing the first infusion fluid (103). The membrane (104) eventually contacts and compresses the openable bag (150). Pressure from the membrane (104) causes the bag (150) to open and discharge its contents out of the infusion device (100).
