    摘要: A fluid container is encompassed by a custom fluid container pressure sleeve, which is configured to wrap around, connect and form to the malleable fluid container such that, when the fluid container pressure sleeve is inflated with a gas, the fluid container pressure sleeve applies an inward directional pressure to the malleable fluid container from an exterior of the malleable fluid container to compress the malleable fluid container. A pump connected to the fluid container pressure sleeve is activated to provide the gas to the fluid container pressure sleeve to compress the malleable fluid container and direct a fluid (e.g., the blood product) within the malleable fluid container toward and through a connected infusion tubing

    摘要: A fluid flow sensing apparatus and method for detecting pressure and the presence of bubbles within a fluid tube. The flow sensor comprises a housing configured to receive a portion of the tube and to house the pressure sensor and the ultrasonic transmitter. The pressure sensor is positioned adjacent the tube and is configured to receive a pressure sensor signal, which correlates to a detected pressure differential within the tube. An internal controller transmits a drive signal to the ultrasonic transmitter, which emits ultrasonic waves through a portion of the tube and to the pressure sensor. The pressure sensor receives both the ultrasonic waves and a pressure sensor signal, and subsequently transmits an output signal to the internal controller. In the presence of a pressure differential or a bubble within the tube, the output signal will exhibit a DC shift or a distortion of its signal characteristics, respectively.
