  "abstract": "An improved emergency code cart (100) is provided. The cart contains a number of drawers (130), each containing medications (305, 310) and instruments (315) required for a particular code algorithm. The contents of each drawer are organized according to ACLS (American Cardiac Life Support) or other guidelines. The cart also contains a computer (175) which is programmed with ACLS algorithms or other guidelines which are the current standard of emergency patient care. The cart's computer monitors the patient's EKG, blood pressure, pulse oximetry, and other indicators, providing diagnostic information to the medical personnel in the code team. Upon select of a code algorithm, the computer provides prompts according to the algorithm, issues alarms when the algorithm is not followed, provides automatic synchronized cardioversion, prints an EKG rhythm strip, and documents all activities occurring in a code, including withdrawal, replacement, and use of medication and instruments.",

  "description_excerpt": "1. Field of Invention\n\nThis invention relates to hospital emergency carts, in particular to carts which contain medications and devices for use in life-threatening conditions.\n\n2. Prior Art\n\nIn U.S. Pat. No. 6,116,461 (2000), Broadfield et al. teach a system and apparatus in which modular receptacles are filled with medications and transported to automatic dispensing machines for later retrieval and distribution. Memory chips, associated with a computer, store and maintain information about the contents of each receptacle, such as expiration dates of drugs and the like. An inventory of the receptacles' contents is automatically maintained as users access each receptacle.\n\nIn U.S. Pat. No. 6,011,999 (2000), Holmes teaches a dispensing apparatus for controlled dispensing of pharmaceutical and medical supplies which includes a cabinet having a plurality of drawers, each containing a plurality of receptacles. The receptacles have lockable lids which are unlocked under the control of an electronic processor. The processor prevents access to contents of the receptacles by unauthorized personnel. It also keeps an inventory of the contents of the cabinet.\n\nPearson, in U.S. Pat. No. 5,292,029 (1994), teaches a dispensing system in a mobile cart. The cart comprises a plurality of containers containing doctor-prescribed medications for individual patients. To dispense medication, a nurse enters a patient ID code into a microprocessor program, the program causes the microprocessor to actuate a mechanism which releases secured medication-dispensing units on the cart.",
