Abstract
A compressed gas actuated, portable fluid delivery system including separate disposable components which provides multiple, precisely rate controlled administration of medical fluids to patients. A pressurization housing includes a holder for a liquid gas cylinder, a mechanism for piercing the cylinder and connecting the cylinder output in a sealed relationship to an output tube through pressure regulators and a pressure gauge. The pressurization housing includes a safety latch interconnected to a pressure on-off valve for preventing opening the housing while pressurized. The output tube leads to a pressure chamber in which a flexible bag containing a fluid to be delivered may be placed. Pressure within the chamber squeezes the bag, forcing fluid through a fluid output tube to, in seriatim, a particulate filter, a binary flow control valve assembly, an air eliminating filter and finally to a fitting adapted to connect to an administration device such as a hypodermic needle, nasal tube or the like. These various components may be included serially in several containers for ease of replacement or in a single unit, as desired.
