  • Patent number: 10086157
    Abstract: Systems and methods to provide respiratory therapy may determine a target pressure level in a current therapy session on the successful completion and/or compliance of a patient (for example for at least a threshold amount of respiratory therapy) during one or more prior therapy sessions. By gradually increasing the provided pressure level, patients may improve compliance, comfort, and/or other indicators of how well-tolerated the respiratory therapy is for a patient.

  • Patent number: 10052259
    Abstract: A system includes a needle hub having a proximal end and a distal end. The proximal end of the needle hub has a connection portion configured to receive a first container. The system further includes a cannula received by the needle hub with the cannula having a proximal end and a distal end and a cannula seal having a resilient sleeve enclosing at least a portion of the cannula. The system also includes a vial adapter configured to be attached to a second container with the vial adapter having a vial seal that is configured to engage the cannula seal. The cannula seal has a first position where the cannula seal encloses the distal end of the cannula and a second position where the cannula seal is retracted to expose the distal end of the cannula.

  • Publication number: 20070221224
    Abstract: A system is provided for delivering a flow of breathing gas to an airway of a patient. The system includes a pressurizing flow module that generates a pressurized flow of breathing gas and a patient circuit coupled to the pressurizing flow module configured to communicate the flow of breathing gas to an airway of a patient. The system includes a sensor for monitoring a characteristic of a breathing pattern of the patient a controller that communicates with the sensor configured to increase a fraction of inspired carbon dioxide if the characteristic exceeds an upper threshold value and to provide servo-ventilation if the characteristic is less than a lower threshold value. The upper threshold value and the lower threshold value are changed based on the monitored characteristic of the breathing pattern of the patient.

  • Publication number: 20050238576
    Abstract: A method and apparatus of dispensing a radiopharmaceutical wherein a source of flushing fluid is connected to a first port of a fluid delivery set; a pressurizing unit of a powered injector system (including a powered injector and the pressurizing unit) is connected to a second port of the fluid delivery set; air is purged from the fluid delivery set; and, after purging air from the fluid delivery set, a third port of the fluid delivery set is connected to a source of the radiopharmaceutical. A valve system is included to control flow of fluid. A syringe is operatively connected with a powered injector. A radioactive shield encloses the syringe during operation to protect personnel from detrimental effects. A dose calibrator measure the radioactivity in the syringe.

  • Patent number: 6770830
    Abstract: Method and apparatus for assaying and sorting radioactive seeds that provides for feeding seeds in line horizontally in end to end fashion; translating the seeds from the horizontal to a vertical stack; singulating the seeds from the vertical stack and moving a singulated seed to a horizontally displaced position; loading the horizontally displaced singulated seed into a shuttle by pushing vertically downward into a cavity in the shuttle; moving the shuttle horizontally from a retracted position where it receives a singulated seed, into one end of an annular dose calibrator to an intermediate position within the dose calibrator and out of the other end of the annular dose calibrator to an unloader position; determining the activity of the singulated seed contained in the cavity while it is in the intermediate position; dropping the singulated seed into one of a plurality of receptacles at the unloader position; and controlling the plurality of receptacles to position a preselected receptacle to receive the si
