Abstract

The specification describes anesthesia systems with an integrated, extendable clinical center and clinician/anesthesia office that accommodates for physical separation of clinical and clerical functions. The disclosed anesthesia systems allow for a portion of the system to be brought closer to the patient such that clinical controls can be accessed while tending to the patient airway, without compromising office space available to the clinician or crowding the patient area.

Claims

1. An anesthesia delivery system, comprising:

a first section comprising support for at least one clinical control and at least one patient connection for providing therapy to a patient, wherein said at least one patient connection includes a breathing circuit connection comprising at least one limb, wherein the at least one limb may be inspiratory, expiratory or a combination thereof;

a second section, comprising a base portion for supporting and housing the first section and at least one pneumatic or electrical connection, wherein the first section is linearly, rotatably or linearly and rotatably extendable relative to the second section, and wherein the second section is pneumatically connected to the first section via a suction supply line or an anesthesia gas supply line; and

a lighting system for indicating a status of at least one function of the anesthesia delivery system by direct illumination.

2. The anesthesia delivery system of claim 1 further comprising adjustable lighting, wherein the adjustable lighting is configured to be adjusted by color, intensity or flash rate.

3. The anesthesia delivery system of claim 1 wherein the lighting system is configured to indicate an anomalous operational condition of the anesthesia delivery system by direct illumination of a portion of the anesthesia delivery system suspected of causing the anomalous operating condition.

4. The anesthesia delivery system of claim 1 wherein the lighting system is configured to indicate when a ventilator within the anesthesia delivery system is in an active state by illuminating a bellows of the ventilator.

5. The anesthesia delivery system of claim 1 wherein the lighting system is configured to indicate when a ventilator within the anesthesia delivery system is in an inactive state by illuminating an APL valve of the ventilator.

6. The anesthesia delivery system of claim 1 wherein the lighting system is configured to indicate when a ventilator within the anesthesia delivery system is in an inactive state by illuminating a pressure gauge of the ventilator.

7. The anesthesia delivery system of claim 1 wherein the lighting system is configured to indicate when a ventilator within the anesthesia delivery system is in an inactive state by illuminating a bag arm of the ventilator.

8. The anesthesia delivery system of claim 1 wherein the lighting system is configured to illuminate a common gas outlet port of the anesthesia delivery system when controls are set to have gas emerge from the common gas outlet port.

9. The anesthesia delivery system of claim 1 wherein the lighting system is configured to illuminate an auxiliary flow tube if auxiliary flow has been turned on.

10. The anesthesia delivery system of claim 1 wherein the lighting system is configured to illuminate a CO₂ absorbent canister indicating a CO₂ level status when the CO₂ absorbent canister is not present in a breathing circuit and/or when there is an alarm for high CO₂ levels in respiratory gas.

11. The anesthesia delivery system of claim 1 wherein the lighting system is configured to illuminate a side stream respiratory gas monitor water trap if a respiratory gas monitor is alarming to indicate an obstruction.

12. An anesthesia system for delivering a predetermined continuous supply of one or more medical gases mixed with a predetermined concentration of an anesthetic vapor to a patient and for monitoring at least a pressure and a flow rate of the delivered medical gases comprising

a lighting system for indicating an operational status of at least one predefined portion of the anesthesia system wherein the lighting system is configured to illuminate the at least one predefined portion of said anesthesia system based upon an operational status of the at least one predefined portion wherein the operational status comprises at least one of on/off, active/inactive, or anomalous operation states and wherein said predefined portion comprises at least one of a bellows, an adjustable pressure-limiting (APL) valve, a pressure gauge, an auxiliary flow control port, or a bag arm.

13. The anesthesia system of claim 12, wherein said lighting system is configured to illuminate a common gas outlet port (CGO) of said anesthesia system when one or more controls are set to allow at least one gas to emerge from said CGO port.

14. The anesthesia system of claim 12, wherein said lighting system is configured to illuminate a common gas outlet port (CGO) of the anesthesia system in a first color if said CGO port is not selected and is in a first vertical, downward facing position, and in a second color when said CGO port is selected via rotating a body of said CGO port from said first vertical, downward facing position to a second horizontal, forward facing position.

15. The anesthesia system of claim 12, wherein the lighting system is configured to illuminate an inspiratory and an expiratory port of the anesthesia system when one or more controls are set to inhibit gas from emerging from a common gas outlet (CGO) port of said anesthesia system.

16. The anesthesia system of claim 12, wherein said lighting system is configured to illuminate a carbon dioxide absorbent canister of said anesthesia system indicating a CO₂ level status when the carbon dioxide absorbent canister is not present in a breathing circuit of said anesthesia system and/or when a level of carbon dioxide gas indicated in a respiratory gas monitor of said anesthesia system rises above a predetermined level.

17. The anesthesia system of claim 12, wherein said lighting system is configured to illuminate a side stream respiratory gas monitor water trap control of said anesthesia system when there is an obstruction in said side stream respiratory gas monitor water trap control.

18. The anesthesia system of claim 12, wherein said lighting system is configured to illuminate multiple portions of said anesthesia system when more than one portion is suspected of causing an anomalous operational state, wherein illumination from the lighting system is configured to vary in at least one of color, flashing rate, pattern, or intensity for guiding a user to inspect illuminated portions in a particular sequence.

19. The anesthesia system of claim 12, wherein the lighting system is configured to illuminate based on a particular lighting pattern and with specific characteristics, wherein said characteristics comprise any one or more of color, flashing rate, and intensity.

20. The anesthesia system of claim 19, wherein said characteristics are user adjustable.
