Anesthesia machine with head worn display
First Claim
1. An anesthesia apparatus comprising:
- (a) a gas delivery assembly adapted for delivering a selected gas to a patient;
(b) a gas delivery control connected to and cooperating with said gas delivery assembly to control a flow volume of said selected gas to a patient;
(c) a gas delivery sensor cooperating with said gas delivery assembly and sensing a gas parameter indicative of said flow volume of said selected gas and generating a gas parameter signal representing a value of said gas parameter;
(d) a patient monitor assembly including at least one patient vital parameter sensor sensing a selected patient vital parameter and generating a patient parameter signal representing a value of said selected patient vital parameter;
(e) a digital patient monitor processor having said gas delivery sensor and said patient parameter sensor interfaced thereto, said digital patient monitor processor executing a program to process data and generating alphanumeric and graphic data;
(f) a display controller interfaced to said digital patient monitor processor and generating a display signal representing alphanumeric and graphic data generated by said digital patient monitor processor including indicia representing said gas parameter and said patient vital parameter; and
(g) a head worn display device interfaced to said display controller, receiving said display signal, and displaying said alphanumeric and graphic data.

Abstract
An anesthesia machine with a head worn display includes a gas delivery system and a patient monitor system cooperating in such a manner as to monitor the anesthesia and vital parameters of a patient in surgery. The gas delivery system supplies oxygen or a gaseous anesthetic at a controlled pressure and flow rate as monitored by gas delivery sensors. The gas delivery sensors and patient vital parameter sensors are interfaced to a monitor processor and the measured values of the sensors can be displayed on a head worn display device having stereoscopic capabilities. The monitor processor includes communication ports for selectively monitoring the sensors of a similar anesthesia machine remotely positioned and for downloading patient medical records from a hospital medical records computer. A wireless communication link can be employed between the monitor processor and the head worn display to facilitate movement of an anesthesiologist about an operating room.
