Abstract: A simulated lung for use in real time simulated medical procedures comprising a positive pressure source of a gas, a vacuum pressure source, a fixed interior volume vessel having an inlet, an outlet, and a breath passage port, the inlet in communication with the positive pressure source, and the outlet in communication with the vacuum pressure source, a first flow valve intermediate the positive pressure source and the inlet, a second flow valve intermediate the vacuum pressure source and the outlet, a pressure sensor in communication with the interior volume of the vessel, and means for continuously evaluating a pressure signal generated by the pressure sensor to a desired pressure level within the vessel during the breathing cycle such that a flow of gas entering and exiting the breath passage port of the vessel is synchronized with a predetermined desired flow rate of breathing during the breathing cycle.

Abstract: A small breath-activated, microprocessor controlled device that can be used with any drug formulation appropriate for pulmonary delivery is disclosed. A fixed-resistor housing incorporates a microprocessor and pressure transducer to detect pressure changes associated with patient derived airflow across the device. The microprocessor determines the flow rate and tidal volume over several breaths and averages them. Depending on where in the brocho-pulmonary tree the drug is to be administered, the microprocessor will precisely meter the drug in the appropriate phase of the respiratory cycle and deliver small aliquots of the formulation over several breaths until the total dose is administered.

Abstract: A method, system, and apparatus for training users in understanding and use of numerous medical devices, including providing for documentation of competency during the training exercise is provided. Preferably, the invention will utilize an “interface module” (e.g., hand-held device, palm size, laptop, desktop PC, microcontroller, expansion module on a palm/hand-held device) to provide the training interface between the user and the device.

Abstract: An open- or closed-loop method and corresponding medical ventilator for providing breathing gas to a patient such that the patient exerts a desired work of breathing during pressure support ventilation, and such that the work of breathing of the patient is monitored and the pressure and/or flow rate of the breathing gas provided to the patient is controlled throughout the inspiratory phase to provide a pressure support ventilation level that provides the desired work of breathing in the patient.

Abstract: The present invention includes a method, system, and apparatus for training users in the understanding and use of numerous medical devices, including providing for documentation of competency during the training exercise. Preferably, the invention will utilize an “interface module” (e.g., hand-held device, palm size, laptop, desktop PC, microcontroller, expansion module on a palm/hand-held device) to provide the training interface between the user and the device. The training interface module preferably provides a common hardware platform that can be connected to various medical devices regardless of manufacturer and is capable of being used as a training module to enable users to learn at their own pace, receive remediation when necessary, and provide documentation of proficiency with the device. For devices with I/O capability connected directly to the training interface module, the user trains using the actual device's input means.

Abstract: The present invention solves this communication problem by providing a method and apparatus for connecting to and coordinating data communications of various medical devices having different communication protocols. In a preferred embodiment, the invention provides a way to recognize common parameters and separate out only that part of the communication that is different between and specific to the various monitors and therapeutic devices. The invention efficiently utilizes defined common parameters for protocol types and selectively configures the specific settings when required, automatically.
