Abstract

The disclosure describes a novel approach for displaying information on a ventilator system. The disclosure describes a novel respiratory system including a removable primary display and system status display. Further, the disclosure describes a novel method for displaying ventilator information and a novel method for controlling a ventilator system.

Claims

1. A ventilation system comprising:

a main housing;

a gas delivery system in the main housing;

a ventilation control system in the main housing that controls the gas delivery system and monitors one or more of a patient physiological parameter, operational parameters of the ventilation system and user-settable parameters;

a primary display controller that generates a graphical user interface and that receives user inputs through the graphical user interface and delivers commands to the ventilation control system based on the inputs;

a primary display housing removably attached to the main housing;

a primary display in the primary display housing that presents the graphical user interface; and

a system status display incorporated into the main housing that receives status data directly from the ventilation control system and displays the status data.

2. The ventilation system of claim 1, wherein:

when the ventilation system is ventilating a patient, the ventilation control system causes the system status display to display a first set of status data when the primary display housing is attached and a second set of status data different from the first set of status data when the primary display housing is removed.

3. The ventilation system of claim 1, wherein:

the primary display controller is in the primary display housing.

4. The ventilation system of claim 1, wherein:

the primary display controller is in the main housing and is placed in a low-power mode when the primary display housing is removed.

5. The ventilation system of claim 4, wherein:

the primary display controller is turned off when the primary display housing is removed.

6. The ventilation system of claim 1 further comprising;

one or more batteries; and

wherein, when the ventilation system is ventilating a patient, the primary display controller and primary display are placed in a low-power mode when the ventilation system is powered from the one or more batteries.

7. The ventilation system of claim 6 further comprising;

wherein, when the ventilation system is ventilating a patient, the primary display controller and primary display are turned off when the ventilation system is powered from the one or more batteries.

8. The ventilation system of claim 1, further comprising:

one or more batteries; and

wherein, when the ventilation system is ventilating a patient, the ventilation control system causes the system status display to display a third set of status data when the ventilation system is powered from an external source and a fourth set of status data different from the third set of status data when the ventilation system is powered from the one or more batteries.

9. The ventilation system of claim 1, wherein:

at least one command may be transmitted to the ventilation control system via the system status display when the primary display housing is removed or turned off.

10. The ventilation system of claim 1, wherein:

status data is selected from ventilator status, primary display status, available gas sources, utilized gas source or sources, available power sources, utilized power source, pressure trace of inspiratory pressure, low pressure level (Peep), peak inspiratory pressure (P_PEAK), battery system status, batteries in use, battery charge level, and a battery status.

11. The ventilation system of claim 1, wherein:

the ventilation control system causes the system status display to display a fifth set of status data when the ventilation system is powered from an external source and the primary display is turned off.

12. The ventilation system of claim 1, wherein:

the system status display when in operation uses less than 10% of the power used by the primary display when in operation.

13. The ventilation system of claim 1, further comprising:

a switch that turns the system status display on and off.

14. A method for displaying ventilator information comprising:

displaying a first set of status data on a system status display;

determining that a primary display is at least one of turned off, disabled, removed from a main ventilator housing, and malfunctioning; and

after the determination step, displaying a second set of status data on the system status display different from the first set of status data.

15. The method of claim 14, further comprising removing the primary display from the main ventilator housing.

16. The method of claim 14, wherein the first set of status data and the second set of status data comprise at least one of ventilator status, primary display status, available gas sources, utilized gas source or sources, available power sources, utilized power source, pressure trace of inspiratory pressure, low pressure level (Peep), peak inspiratory pressure (P_PEAK), battery system status, batteries in use, and battery charge level.

17. The method of claim 14, further comprising utilizing less than 50% of power used by the primary display when in operation to power the system status display when in operation.

18. A method for displaying ventilator information comprising:

displaying a first set of status data on a system status display;

determining that a ventilation system is receiving power only from one or more batteries; and

after the power determination step, displaying a second set of status data on the system status display different from the first set of status data.

19. The method of claim 18, further comprising:

determining that a primary display is at least one of turned off, disabled, removed from a main ventilator housing, and malfunctioning; and

after the primary display determination step, displaying a third set of status data on the system status display different from the first set of status data and different from the second set of status data.

20. The method of claim 18, further comprising utilizing less than 50% of power used by the primary display when in operation to power the system status display when in operation.
