Abstract
Examples described herein include multiple control systems for medical devices, such as medical ventilators. Examples of multiple control of a medical ventilator in an isolation room are described.
Core Innovation
The invention relates to a medical ventilation system in which a ventilator in a second area is medically isolated from a first area, while still being visible to a first interface in the first area. The system includes a first interface in the first area with a first monitor configured to present data related to control of the ventilator and a first input device configured to receive a first command, together with a first communication device that communicates the first command to a controller. The second area includes a second interface that provides a second monitor and a second input device configured to receive a second command, and a second communication device that communicates the second command to the same controller inside the second area.
The controller inside the second area receives the first command from the first communication device and receives the second command from the second communication device. The controller controls the ventilator responsive to a command received, so that ventilation functions can be provided to a patient in the medically isolated second area using commands issued from either the first area or the second area. The system includes a first communication path coupled to the first communication device and traversing between the first area and the second, and a second communication path in the second area, each configured to carry commands to the controller.
In addition, the controller prioritizes overlapping commands and verifies operator/operator-interface state before accepting commands. The system provides for a predetermined time threshold so that an earlier command is discarded if a later command is received within a predetermined time interval. The controller verifies a state that the first interface is visible to the controller responsive to receiving control information and rejects the first control information or command if the state cannot be verified, with optional user alert behavior through the second interface when verification fails.
Claims Coverage
The independent claims cover a medically isolated two-area control architecture for ventilators, including visibility/state verification and command prioritization behavior. Inventive features are described across independent claims covering both system apparatus and methods, with conditional acceptance/rejection rules and prioritization based on command timing and verified visibility/state.
Medically isolated two-area ventilator control with first and second interfaces
A medical ventilation system including a first interface inside a first area with a first monitor, a first input device, and a first communication device; a second interface inside a second area with a second monitor, a second input device, and a second communication device; a ventilator inside the second area medically isolated from the first area and configured to be visible to the first interface while the first interface is in the first area and to provide treatment to a patient; and a controller inside the second area configured to receive the first command and the second command and to control the ventilator responsive to a command received, with a first communication path traversing between the first area and the second area and a second communication path in the second area each configured to carry commands to the controller.
Command prioritization by predetermined time threshold
A controller receives the first command and the second command and, when the second command is received within a predetermined time after the first command is received, discards the first command and controls the ventilator responsive to the second command.
Visibility/state verification and rejecting first command
A medical ventilation system where the controller verifies a state that the first interface is visible to the controller responsive to receiving the first control information, and rejects the first control information if the controller fails to verify the state.
Method of controlling a ventilator with isolated areas and visibility verification
A method comprising clinically isolating a first area from a second area; electrically coupling a first interface in the first area to a controller in the second area; electrically coupling a second interface in the second area to a controller in the second area; transmitting first control information to the controller from the first interface; transmitting second control information to the controller from the second interface; receiving the first control information and the second control information by the controller; verifying a state that the first interface is visible to the controller responsive to receiving the first control information; accepting the first control information if the state is verified; and controlling the ventilator in the second area to provide treatment to a patient in the second area responsive to the accepted first control information.
Operator view with restricted operator position in a third area
A method further including providing a view of the ventilator to an operator while the operator is entering the first command in the first area, and restricting a position of the operator within a third area within the first area that the view is available to the operator.
Across the independent claims, the system and method center on a ventilator controller in a medically isolated area that receives commands from interfaces in different areas, includes visibility/state verification for accepting or rejecting first control information, and supports prioritization behavior using a predetermined time threshold, while also restricting operator position when providing a view of the ventilator.
Stated Advantages
Helps ensure that control commands are accepted only when a state that the first interface is visible to the controller is verified.
Rejects first commands or control information when verification fails.
Provides priority between overlapping commands by discarding an earlier command when a later command arrives within a predetermined time threshold.
Provides a view of the ventilator to an operator while entering a command and restricts operator position within a third area where the view is available.
When verification fails, optionally issues an alert to a user through a second interface.
Documented Applications
Controlling a ventilator to provide treatment to a patient in a medically isolated second area while commands are entered from a first area and/or the second area.
