  • Patent number: 5918597
    Abstract: A piston ventilator is provided which advantageously monitors the positive end expiratory pressure (PEEP) in a patient circuit for supplying breathable gas to a patient, and controls a shiftable valve element in an exhalation valve to regulate the amount of resistance during the exhalation portion of the patient's breath. The shiftable element is preferably an inflatable diaphragm which receives a pneumatic signal through a signal conduit. The pressure provided by the signal conduit is controlled by the amount of gas vented by a PEEP valve, wherein the greater the opening of the PEEP valve, the greater the amount of gas from the patient circuit is vented therethrough and consequently the less the restriction is provided in the exhalation valve.

  • Patent number: 5881721
    Abstract: Apparatus for orienting elongate objects, for example capsules of medicament, comprises a passage for receiving an individual capsule in a preferred orientation, a container for holding a bulk supply of capsules, and a ramp surface which directs a capsule towards the passage when the device is positioned such that the passage extends vertically downwardly from the container. It has been found that by appropriate choice of ramp angle, passage diameter and container diameter there is a high probability that a single capsule will be loaded into the dispensing passage when the apparatus is inverted to place the dispensing passage below the bulk supply. The apparatus is particularly useful in a dry medicament dispensing apparatus comprising, in addition to the orienting apparatus, a chamber for receiving capsules from the dispensing passage, means for piercing the ends of the capsule, and a mouthpiece for drawing air through the capsule and to entrain the medicament.

  • Patent number: 5878744
    Abstract: In a ventilator system and a method of operating the ventilator system, the ventilator system has a ventilator and a connection system for connecting the ventilator system to a patient. Parameters for a respiration gas pattern are set on the ventilator. Due to the influence of the connection system on the respiration gas pattern, the generation of the respiration gas pattern needs to be calibrated in order to ensure that the set respiratory gas pattern is delivered to the patient. In order to obtain calibration factors a test gas pulse is generated by an inspiration system before connecting the patient. Measurements of the test gas pulse are made with parameter meters at different locations in the connection system. The parameters for the test gas pulse, as well as the measured parameters are stored in different data sets. By synchronizing and subtracting measured parameter data sets from the set parameter data set, calibration factors are obtained.
