Abstract
A nitric oxide delivery device including a valve assembly, a control module and a gas delivery mechanism is described. An exemplary gas delivery device includes a valve assembly with a valve and circuit including a memory, a processor and a transceiver in communication with the memory. The memory may include gas data such as gas identification, gas expiration and gas concentration. The transceiver on the circuit of the valve assembly may send wireless optical line-of-sight signals to communicate the gas data to a control module. Exemplary gas delivery mechanisms include a ventilator and a breathing circuit. Methods of administering gases containing nitric oxide are also described.
Core Innovation
The invention provides a gas delivery system for therapeutic gas in which a cart receives a gas source of therapeutic gas. The gas source has a valve transceiver, and a control module interconnected with the cart includes a processor. The cart includes a cover portion having a control module transceiver in communication with the control module so that the control module transceiver receives gas data associated with the therapeutic gas from the valve transceiver.
The gas data includes at least one of gas identification, gas expiration, and gas concentration. The processor controls inflow of the therapeutic gas according to whether the gas data meets at least one predetermined criteria, so the control module regulates delivery based on information received from the valve transceiver.
In a nitric oxide delivery system embodiment, the cart has a receptacle configured to receive a source of nitric oxide, and the nitric oxide source has a valve transceiver. The control module is disposed at an upper portion of the cart and the cover portion has a control module transceiver on a lower side, where the control module transceiver receives gas data from the valve transceiver, and the processor controls inflow of nitric oxide according to predetermined criteria.
The disclosed system further supports configurations with desired gas information stored on control module memory and compares that desired gas information to received gas data from at least one valve transceiver. In arrangements with first and second nitric oxide sources, the first and second valve transceivers and the first and second control module transceivers communicate via optical line-of-sight signals to receive gas data associated with each source and to control inflow based on whether predetermined criteria are met.
Claims Coverage
The independent claims are clm-00001, clm-00009, and clm-00015. Across these claims, the inventive features center on receiving gas data from valve transceivers using a cart/control-module transceiver arrangement and using a processor to control nitric oxide/therapeutic gas inflow based on predetermined criteria, including comparison with desired gas information and optical line-of-sight communication for multiple sources.
Cart receiving therapeutic gas with valve transceiver and cover control-module transceiver
A cart having a receptacle configured to receive a gas source of therapeutic gas, wherein the gas source has a valve transceiver, and wherein the cart includes a cover portion having a control module transceiver in communication with the control module.
Control of therapeutic gas inflow based on received gas data
A control module interconnected with the cart and having a processor, wherein the control module transceiver is configured to receive from the valve transceiver gas data associated with the therapeutic gas, wherein the gas data includes at least one of gas identification, gas expiration and gas concentration, and wherein the processor is configured to control inflow of the therapeutic gas according to whether the gas data meets at least one predetermined criteria.
Nitric oxide delivery system with upper control-module arrangement and line-of-sight transceiver communication
A cart having a receptacle configured to receive a source of nitric oxide, wherein the nitric oxide source has a valve transceiver, wherein a control module is disposed at an upper portion of the cart, and wherein the cart further has a cover portion in communication with the control module, wherein the cover portion has disposed on a lower side a control module transceiver, wherein the control module transceiver is configured to receive gas data from the valve transceiver, and wherein the control module includes a processor configured to control the inflow of nitric oxide according to whether the gas data meets at least one predetermined criteria.
Nitric oxide system comparing desired gas information to received gas data for inflow control
A cart having a lower portion and a first and second receptacle configured to receive first and second sources of nitric oxide, wherein the first nitric oxide source has a first valve transceiver and the second nitric oxide source has a second valve transceiver, a control module disposed at an upper portion of the cart, and a cover portion in communication with the control module with first and second control module transceivers on a lower side, wherein the first control module transceiver communicates via optical line-of-sight signals with the first valve transceiver and receives gas data associated with the first nitric oxide source and the second control module transceiver communicates via optical line-of-sight signals with the second valve transceiver and receives gas data associated with the second nitric oxide source, wherein the gas data includes at least one of gas identification, gas expiration and gas concentration, and wherein the control module includes a processor configured to compare desired gas information stored on a control module memory to the gas data received from at least one of the first and second valve transceivers and control inflow of nitric oxide from the associated nitric oxide source according to whether at least one predetermined criteria is met.
Across the independent claims, the core coverage is for a cart-based delivery system in which transceivers on the gas source(s) and the control module/cover exchange gas data including gas identification, gas expiration, and gas concentration, and a processor controls nitric oxide/therapeutic gas inflow based on whether that gas data meets predetermined criteria, including comparison with desired gas information and optical line-of-sight communication in multi-source configurations.
