  • ABDOMINAL CIRCULATORY PUMP DEVICE
    Publication number: 20120016280
    Abstract: The abdominal circulatory pump uses expulsive manoeuvres performed by contraction of the diaphragm while stabilizing, contracting or compressing the abdominal wall to increase abdominal pressure and pump blood. At the same time, it can be used to lower pleural pressure around the surface of the lung to provide ventilation. In humans the blood in the splanchnic circulation; i.e., the blood in the abdominal contents, is a reservoir of about 20% to 25% of the whole body blood volume. The increase in abdominal pressure forces this blood to flow out of the abdomen and through the body.

  • Measurement of airway calibre
    Patent number: 6074350
    Abstract: The variation in flow resistance of the respiratory system (Rrs) is determined as an indicator of variations in airway calibre, by oscillating the system, for example at 6 Hz for 5-15 minutes and determining the variations in ratio of the pressure difference (Prs) across the system that is in phase with flow, to flow V. The variation in airway calibre may be employed as a prognostic indicator in asthmatics and also to assess the efficacy of treatment.
