  • Publication number: 20060106345
    Abstract: Disclosed is an interface between a drug delivery cassette and a medical effector system. The cassette may be mounted to the medical effector system in such a way that a fluid tube located on the cassette is positioned adjacent to a pump located on the medical effector system. The medical effector system may purge the fluid line of air by activating the pump and forcing fluid through the fluid line until a sensor positioned to monitor the fluid line indicates that fluid and not air is present in the tube. To prevent air purging of the fluid tube when connected to the patient, the medical effector system prohibits air purging unless the drug delivery end portion of the fluid tube is in a designated storage site located on the cassette. This is accomplished with a position sensor at the storage site that monitors the position of the fluid tube.

  • Publication number: 20060081259
    Abstract: A medical effector system comprised of a bedside unit and a procedure unit. The bedside unit contains a series of connection points for receiving inputs from a series of patient monitors. The procedure unit contains a patient monitoring and medical effector program, and a drug delivery pump or magnetic flux generator capable of delivering therapeutic energy to a patient. The medical effector system contains the capability to issue and receive a request from a non-sedated patient, issue and receive a request from a sedated patient and then to calculate a time difference. The medical effector program operates the pump or magnetic flux generator based upon at least some of the patient outputs and program inputs including a calculated time difference. A removable umbilical cable connects the two units and allows the output of the patient monitors as well as other information to travel between the two units.

  • Publication number: 20060042635
    Abstract: Disclosed is a capnometry apparatus for receiving respiratory gas from a respiratory cannula positioned on a patient. An integrated host controller alerts a user if the capnometry apparatus is connected or not connected to the respiratory cannula based in part on a signal output from a capnometer located in the capnometry apparatus. The host controller also includes the functionality to shut off the capnometer pump with or without a time delay when the capnometer signal output indicates the capnometer pump is not connected to the cannula. An ambient-air pressure sensor located in the capnometry apparatus alerts the host controller if the capnometry apparatus has been moved to a new location with a substantially different altitude than the first location, in which case the host controller will issue an alert to a user prompting a calibration of the capnometry apparatus.

  • Publication number: 20060042634
    Abstract: Disclosed is a device for coupling a respiratory cannula with a medical effector system. The coupling device consists of a plate with several ports for receiving respired gases from the respiratory cannula and for delivering oxygen or air to the respiratory cannula. The coupling device may directly or indirectly deliver the respired gases to a capnometry device located in the medical effector system. Also included is a port for delivering an audio signal from the medical effector system to an audio earpiece disposed proximate the ear of a patient.

  • Publication number: 20060042638
    Abstract: Disclosed is an oxygen delivery apparatus constructed from an oxygen delivery manifold, a respiratory cannula, and a host controller. The host controller contains an oxygen delivery program and accepts a respiration input regarding whether the patient is inhaling or exhaling, and whether the patient is breathing orally or nasally. The oxygen delivery program regulates the flow rate of oxygen based in part upon the respiration input provided. A first rates is used when the patient is inhaling and exhaling orally, a second rate is used when the patient is inhaling nasally, and a third rate is used when the patient is exhaling nasally.

  • Publication number: 20050070822
    Abstract: A conscious sedation system and a response testing apparatus for a conscious sedation system. A controller generates a request for a predetermined hand motion response from a patient and analyses at least a hand motion response made by the patient to the request to determine a level of sedation of the patient. The response testing apparatus includes a request assembly and a response assembly. The request assembly communicates to the patient the request generated by the controller. The response assembly senses the hand motion response and communicates the hand motion response to the controller.
