초록 ▼

An air detector according to the present invention utilizes a unitary type sensor for detecting air bubbles or columns in an infusion solution flowing through a tube. Because of a unique design for a tube-receiving groove and a cooperating abutting member, the difficulty in loading a tube heretofore encountered with the use of unitary type sensor is obviated. Thus, the tube can be loaded in the air detector easily with good reliability.

대표청구항 ▼

In an air detector for detecting air bubbles or columns in an infusion solution flowing through a tube located in a pumping station, the tube extending from a supply bag of the infusion solution to a patient through the detector between a signal emitting member and a signal receiving member the air detector comprising: a stationary unit of the pumping station including; a groove including a base and two side walls for receiving the tube; an upper section of the groove being defined by a first side wall which flares outwardly from a tube-fixing section and a second side wall which is perpendicular to the base of the groove along its length in the tube-fixing section; and a movable unit in pivoting relation to said stationary unit of the pumping station; and a tube-abutting member movable into said groove when said movable unit is closed, whereby when said tube is pushed into said tube fixing section from the upper section by said tube abutting member, dislodgement of said tube from said groove is prevented by said second side wall.
