20140174443 | VENTILATOR APPARATUS - One or more embodiments of the presently described invention provides a ventilator including a timing device, an electric power source and a flow control device. The timing device is electronically controlled and is capable of controlling a period of time that a fluid is delivered to a patient. The timing device can control this period of time using a solenoid. The flow control device controls a rate of flow that the fluid is delivered to the patient. The flow control device can control the rate of flow using a plurality of orifices. The timing device and flow control device are separate from one another and each is capable of being operated independent of the other. | 06-26-2014 |
20130064687 | SHUTTLING BY-PASS COMPRESSOR APPARATUS - A compressor apparatus having a first compressor head for generating a first gas flow and a second compressor head for generating a second gas flow with a shuttling by-pass component in fluid flow communication between the first and second compressor heads for allowing the output of a portion of either the first gas flow or the second gas flow to be diverted to the other compressor head. The shuttling by-pass component allows a portion of the first gas flow to be diverted from the first compressor head to the second compressor head during an exhaust stroke of the first compressor head, while also allowing a portion of the second gas flow to be diverted from the second compressor head to the first compressor head during an exhaust stroke of the second compressor head in alternating sequence such that a more steady output of gas flow may be attained. | 03-14-2013 |
20130055887 | MULTIPLE VALVE HEAD COMPRESSOR APPARATUS - A multiple valve compressor head having a casing defining an intake chamber in selective communication with a cavity through a plurality of one-way intake valves and an exhaust chamber in selective communication with the cavity through a plurality of one-way exhaust valves is disclosed. The casing further defines an inlet port for the entry of gas into the intake chamber and an outlet port for forcing out compressed gas from the exhaust chamber. In operation, the multiple valve compressor head is in operative engagement with a reciprocating diaphragm that draws the gas into the intake chamber and then the cavity during the intake stroke of the diaphragm, while expelling compressed gas from the cavity and through the outlet port during the exhaust stroke of the diaphragm. | 03-07-2013 |
20120060840 | VENTILATION SYSTEM - A ventilation system having a processor in communication with a mechanical ventilator and a user interface for allowing an individual to operate the system with little or no respiratory care expertise until a respiratory care practitioner can take over operation is disclosed. The ventilation system further includes a function that permits seamless transition between modes of operation. | 03-15-2012 |
