Abstract
The invention relates to a self-parameterizable method for detecting occlusion and pulling out of a tubing for ad-ministering, by enteral route, physiological liquids and to a device for carrying out said method. The inventive device comprises, in essence: a pump (1); an administering tubing (2, 3); a tri-route tubular structure (4, 5, 7) provided with an occlusion detection area (7); a computer (14) and an electromagnetic detection means (8, 9) for detecting the presence of a fluid in said detection area (7) and for detecting a pulling out of said tri-route structure; an electromagnetic detection means (15, 16) for detecting the presence of air inside the dispensing tubing and the pulling out thereof. The inventive method is characterized, in essence, in that it consists of, in the event of repetitive occlusions, programming the computer (14) for systematically and automatically calculating the intensity of the wave received by the receiver (9) at the time of each occlusion and using this value as a reference value for determining the new detection intensity threshold to use during each starting or restarting.

12. A method for detection of occlusion and pulling out of a tubing of an apparatus for the administration, by enteral pathway, of physiological liquids, the apparatus including:
-
a) a pump; b) an occlusion detection device including; a fluid inlet zone coupled to a first part of the tubing and a fluid outlet zone coupled to a second part of the tubing; a zone, configured for the detection of an occlusion, arranged along a direction substantially perpendicular to the direction of flow of the fluid, forming a tri-route tubular structure, arranged so that the fluid enters the detection zone in case of occlusion of the second part of the tubing; a detector configured to detect the presence of a fluid in the detection zone, the detector including an emitter of an electromagnetic wave and a receiver of the electromagnetic wave; and a computer programmed to measure the intensity of the electromagnetic wave received at the receiver in order to detect the presence of the fluid in the detection zone when the intensity of the electromagnetic wave reaches a predefined threshold and trigger an alarm, the method comprising programming the computer to automatically measure an intensity of the wave received by the receiver at the time of each occlusion; and using the measured intensity as a reference value for determining a new threshold of intensity detection to use at each start-up or reboot. - View Dependent Claims (13, 14, 15, 16, 17, 18)
