  • Publication number: 20130046279
    Abstract: A medical system includes a monitoring unit and a drug delivery unit. The monitoring unit is operable to monitor at least one physiological parameter of a patient. The drug delivery unit includes an integral volume of a drug. A control logic is in communication with the monitoring unit and the drug delivery unit and is operable to regulate delivery of the drug to the patient from the integral volume, based on data associated with the at least one physiological parameter of the patient, in accordance with a safety shell control algorithm. A user interface feature is operable to receive input indicating administration of an external drug to the patient. The safety shell control algorithm responds to inputs received through the user interface feature indicating administration of an external drug to the patient, such as by modifying subsequent drug delivery regulation based on the administration of the external drug.

  • Publication number: 20090292179
    Abstract: A medical system includes a display monitor and a medical unit. The medical unit is adapted to measure a physiological parameter of a patient. The medical unit is adapted to wirelessly connect to the display monitor, wherein the display monitor is adapted to display the physiological parameter. In one implementation of the medical system, the medical unit is adapted to automatically wirelessly connect to the display monitor when the medical unit is brought into proximity with the display monitor. In one illustration of the medical system, the physiological parameter is a pulse rate of the patient.

  • Publication number: 20090292226
    Abstract: A medical system includes a muscular-tension-measuring device and a drug delivery assembly. The muscular-tension-measuring device is operatively connectable to a patient and includes a device output having a device output signal which varies with involuntary changes in muscular tension of the patient. The drug delivery assembly is operatively connectable to the patient for controllably delivering at least one drug to the patient. In one implementation, the device output signal varies with involuntary changes in muscular tension of the patient caused by pain and/or anxiety. In one employment, drug delivery is varied by a controller or a user based at least on variations in the device output signal. A method for conscious sedation of a patient includes measuring muscular tension of the patient and includes varying delivery of a conscious sedation drug to the patient based at least on variations in the measured muscular tension of the patient.

  • Publication number: 20010034536
    Abstract: The present invention provides a surgical device having a tissue engaging portion, a shaft member, and a handle assembly. The tissue engaging portion includes first and second opposed jaws for grasping, securing and occluding body tissue and conduits. The shaft member is operatively coupled to the tissue engaging portion and is capable of being placed in different curvatures. The handle assembly is operatively coupled to both the shaft member and to the tissue engaging portion. The shaft member of the present invention allows the surgeon to bend and adjust the shape of the surgical device of minimize its intrusion and to allow for proper positioning in predetermined body locations. In a preferred embodiment, a portion of the device is disposable.

  • Patent number: 5265183
    Abstract: A fiber optic connector includes a housing having a longitudinal passage extending therethrough and having two ends. A rear end is adapted for attaching a fiber optic cable therethrough. A front end is adapted for having a mating fiber contact plug secured thereto in the passage. The plug has a fiber-receiving passage coextensive with the passage in the housing. A retaining ring is disposed in a transverse groove in the passage in the housing for abutment against the fiber contact plug near the front end thereof to secure the plug in the passage in the housing. A tool is provided for assembling the fiber optic connector. The tool includes a head for receiving and holding the housing of the connector in position with the fiber contact plug and retaining ring insertable into the passage thereof. A pusher apparatus is mounted for movement relative to the head and is engageable with the retaining ring to push the retaining ring into the groove while the connector housing is held by the head of the tool.
