International Classification:

A61M 3700

US Classification:

604131, 604 82

Abstract:

A bedside-pharmacy system for the preparation and delivery of intravenous drugs. The system includes a liquid inlet for connection to a liquid supply, vial receptacles, and a liquid outlet for providing the intravenous drug in mixed, liquid form to the patient. The system may include a chamber having a variable volume, and a valve mechanism, which may be actuated to control flow between the liquid outlet, the variable-volume chamber, the vial receptacles and the liquid inlet. The system induces change in the volume of the variable-volume chamber and actuates the valve mechanism, so as to introduce liquid from the liquid inlet into the vials and reconstitute or dilute the drugs and so as to deliver the drugs to the patient. In a preferred embodiment, the liquid inlet, the vial receptacles, the variable-volume chamber, the liquid outlet and the valve mechanism (in other words, all components that come into contact with the liquid) are located in a disposable cassette, which may be received in a control unit. The system may include means for changing the chamber volume and actuating the valves so as to move the liquid repeatedly between a vial and the chamber.

International Classification:

A62B 1802

US Classification:

12820525, 12820713

Abstract:

A breathing mask for delivering oxygen to a patient. The breathing mask has a headset for seating about the cranial region of the head of the patient, with a hollow gas delivery arm coupled to the headset.

International Classification:

A61M 1600

US Classification:

12820418, 12820422, 12820423, 12820426

Abstract:

An apparatus, method and system for non-invasive breathing assistance to a patient. The apparatus comprises a hose or other gas conduit with a valve. Proximity of the patient to a sensor causes the valve to open, directing a pressurized stream of air or other gas at the patients mouth, assisting the patient in breathing.

US Classification:

604131, 604 67, 604 85, 604 89, 141 1, 141 83

Abstract:

A disposable cassette for mixing an intravenous drug in a vial to a patient includes a liquid inlet for connection to a liquid supply, a first vial spike, a second vial spike and a chamber. The chamber, the first and second vial spikes, and the liquid inlet are in fluid communication with each other. A valve mechanism may be actuated to control flow between the chamber, the vial receptacles and the liquid inlet.

International Classification:

F02C 9/00

US Classification:

60 392, 60517

Abstract:

A system for distributed utilities including electrical power and water. A generation device is provided for converting an available resource to a desired utility; the resource may be water, in which case the generator is a purifier for purifying untreated water, or, alternatively, the generator may convert a fuel to electrical power. In either case, an input sensor is provided for measuring input to the generation device, while an output sensor is provided for measuring consumption of output from the generation device. The monitoring system has a controller for concatenating measured input and consumption of output on the basis of the input and output sensors. Measured parameters are telemetered to a remote site where utility generation and use are monitored and may also be controlled. At least a portion of the electrical power capacity of the electric generation unit may power a water purification unit such as a vapor compression distillation unit, and heat output of the electric generation unit may supply heat to the water purification unit.

US Classification:

Abstract:

A system, device, and method for mixing liquids involves pumping a first liquid into a first pump chamber of a pumping apparatus through a channel of the pumping apparatus and pumping a second liquid from a second pump chamber of the pumping apparatus into either the channel or the first pump chamber, preferably while the first liquid is being pumped into the first pump chamber, so that the two liquids are mixed within the pumping apparatus. The second liquid is preferably pumped in a pulsatile mode in which small quantities of the second liquid are pumped at intervals. The quantity and/or the interval can be dynamically adjusted to result in a predetermined concentration of the two liquids. The contents of the first pump chamber are pumped to a receptacle.
