    摘要： A feeding set adaptor and related system for delivering solutions utilize a feeding set adaptor which engages a pump engaging portion of an infusion set and the feeding set adaptor structure to provide monitoring portions for detecting pressures within the infusion set, a sample cell for determining the presence of air within an infusion set, and an anti-freeflow device for selectively preventing freeflow through the infusion set. The feeding set adaptor is configured for mounting on an infusion pump which moves solution through the infusion set for delivery to a patient.

    摘要： An optical pressure monitoring system includes a tube from an infusion set and an optical signal sensor disposed to detect changes in the diameter of the tube and thereby determine pressure changes within the tube. By selecting the position of the tube relative to the optical signal emitter and optical signal receiver, the optical signal sensor can both detect pressure changes and provide an integrity check for both the functioning of the optical signal sensor and the placement of the tube. By modifying the tube to exaggerate changes in tube diameter responsive to pressure changes, the sensitivity of the optical signal sensor can be increased.

    摘要： A pressure monitoring enteral feeding system and method are disclosed including a housing having a pair of channels for receiving a pump tubing segment which connects an intake line and an output line of a delivery set, and for holding the pump tubing segment adjacent a motor unit. A pair of pressure sensors are disposed along the channels to monitor the pressure in the pump tubing segment so as to warn a user when an undesirable pressure has developed either upstream or downstream from the motor unit, and to adjust rate based on the upstream pressure. The housing may also include a lockable cover to securely hold the pump tubing segment in the channels and in firm contact with the pressure sensors. In accordance with one aspect of the invention, the pressure sensors are used to determine the actual output of the enteral feeding pump by monitoring strain in the delivery set. The pump can then make adjustments to the length of time the rotor turns during each cycle to ensure that partial occlusions, viscosity changes and back pressure do not interfere with proper dosing.

    摘要： An apparatus for determining fluid pressure within flexible tubing has a magnet and a multidimensional magnetic sensor arranged to detect a magnetic field of the magnet along at least two dimensions. The magnetic sensor and the magnet are arranged such that a location of the magnet relative to the magnetic sensor varies as a function of the fluid pressure within the tubing, and a direction of a magnetic field vector at the magnetic sensor is dependent upon the location of the magnet relative to the magnetic sensor. The magnetic sensor detects at least two magnetic field strengths corresponding to strength of the magnetic field projected along each of the at least two dimensions, and generates an output signal related to the direction of the magnetic field vector at the magnetic sensor. The direction of the magnetic field vector is used as an indicator of the fluid pressure.
