Abstract:
1. An anesthesia cart comprising a cabinet having a base, a front, a rear, and a top; a computer control arrangement mounted on said cabinet and including a computer processor, a data entry device, and a key code reader mounted in the cabinet and being coupled to said computer processor; at least one general use drawer in said cabinet including an electro-mechanical lock coupled to said computer processor; a controlled-materials drawer in said cabinet having a plurality of lockable compartments and having one or more motors for locking and unlocking the plurality of lockable compartments; and a sonic presence sensor mounted on said cabinet and centered thereon, having a beam centered in the direction facing past the front of the cabinet and configured for detecting presence or absence of a user within a given beam volume and within a predetermined range of said sonic presence sensor past the front of said cabinet and providing an output signal indicating the presence or absence of the user to said computer processor, wherein said predetermined range of the given beam volume of said sonic presence sensor is substantially eighteen inches in front of said cabinet and said given beam volume is of sufficient width to detect the user immediately in front of the anesthesia cart; said key code reader cooperating with said computer control arrangement to communicate with the electro-mechanical lock of said at least one general use drawer and to communicate with a respective motor of the one or more motors of said plurality of lockable compartments, and respond to presence of an anesthesia authorization code to unlock said at least one general use drawer to permit access to said at least one general use drawer; to await entry of an authorized pass code on said data entry device; and, upon entry of said authorized pass code, to unlock one of the plurality of lockable compartments in said controlled-materials drawer; and said computer processor being suitably programmed and configured to maintain the at least one general use drawer in an unlocked condition so long as said sonic presence sensor provides said output signal indicating that the user is present within said given beam volume, and to re-lock said at least one general use drawer and to re-lock the respective lockable compartment of said controlled-materials drawer in response to the output signal of said sonic presence sensor indicating that the user is absent from said given beam volume.
