초록 ▼

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.

대표청구항 ▼

A medical fluid delivery system which comprises: a first container adapted to hold a high pressure liquid gas cylinder of the sort having a piercable seal at one end; a piercing needle located adjacent to the cylinder in said container: means for moving said needle and cylinder together so that said needle pierces said seal permitting high pressure fluid to enter said needle: an on-off valve receiving fluid from said needle, said on-off valve includes a knob rotatably with said valve between off and on positions, said knob adapted to extend outwardly of a container lid, said knob having an outwardly extending finger and said lid having a hole and slot arranged so that said knob and finger can pass through said slot only when said valve is in the off position, and said knob being rotatable to the on position with said lid closed, whereby said finger then overlaps a portion of the lid, latching said lid in the closed position; pressure regulation means adapted to receive fluid from said valve and reduce pressure to a selected gas pressure level: a gas tube conveying gas from said pressure regulation means to a pressure chamber: said pressure chamber adapted to contain at least one flexible medical fluid containing bag filling part of the pressure chamber volume: an outlet tube selectively connectable to said medical fluid bag passing through the pressure chamber walls a binary flow control means connected to said outlet tube and adapted to control fluid flow rate: and means adapted to connect the outlet of said flow control means to a patient administration means.
