Appl. No.:

11/201053

Inventors:

Robin L. Roehl - Janesville WI, US
Craig R. Tolmie - Stoughton WI, US

Assignee:

The General Electric Company - Schenectady NY

International Classification:

A61M 16/00
A61M 16/20
A61M 16/10
A61M 16/14

US Classification:

12820421, 12820227, 12820312, 12820325, 12820418, 12820524

Abstract:

A nitric oxide delivery device is provided that can be formed as a module that is insertable in a mating equipment bay in a gas delivery system found in one location, removed and used in conjunction with a transport gas delivery system when the patient is transported, and thereafter inserted in the equipment bay of a gas delivery system located at a second location. In a preferred embodiment, the device includes a housing having an NO supply port, an NO delivery port, a flow sensor port, and a conduit pneumatically connected to the NO supply port and the NO delivery port. A selector valve is positioned in the conduit and selectively moves between a first position wherein the NO supply port is pneumatically connected to the NO delivery port and a second position wherein the NO delivery port is pneumatically connected to a temporary supply of NO. The housing further has a power supply port, a temporary power source and a switch being selectively movable between a first position wherein power is provided to the NO delivery device via the power supply port and a second position wherein power is provided to the device from the temporary power source.

International Classification:

A61M 1100

US Classification:

12820422

Abstract:

A system and method for estimating the NO. sub. 2 concentration in the gas provided to a patient. The therapy of using nitric oxide to threat the lungs of a patient includes administering that gas along with a gas containing oxygen. Since the mixing of NO and oxygen cause a reaction leading to the formation of NO. sub. 2 and which is toxic, the method and system determine the concentration of oxygen in the oxygen containing gas, the concentration of NO in the NO containing gas and the residence time between the time those gasses are mixed together to the time that mixture is administered to the patient. Those values are then used, preferably in a microprocessor to access a look up table in the memory of the processor, to thereby provide an estimation of the NO. sub. 2 concentration of the gas administered to the patient.

International Classification:

A61M 1600

US Classification:

12820421

Abstract:

Respiratory therapy apparatus is provided with setting elements such as knobs for inputting set values for various parameters. A digital display is provided for showing measured values of operational variables. The set point for each parameter is displayed on the display apparatus along with the measured values only when the knob or setting element for the particular parameter is engaged by the operator's hand.

Abstract:

Therapy gas delivery systems that provide run-time-to-empty information to a user of the system and methods for administering therapeutic gas to a patient. The therapeutic gas delivery system may include a gas pressure sensor attachable to a therapeutic gas source that communicates therapeutic gas pressure data to a therapeutic gas delivery system controller, a gas temperature sensor positioned to measure gas temperature in the therapeutic gas source that communicates therapeutic gas temperature data to the therapeutic gas delivery system controller, at least one flow controller that communicates therapeutic gas flow rate data to the therapeutic gas delivery system controller, at least one flow sensor that communicates flow rate data to the therapeutic gas delivery system controller, and at least one display that communicates run-time-to-empty to a user of the therapeutic gas delivery system. The therapeutic gas delivery system controller of the system includes a processor that executes an algorithm to calculate the run-time-to-empty from the data received from the gas pressure sensor, temperature sensor, flow controller and flow sensor, and directs the result to the display.
