Abstract
A detection device according to the present disclosure includes: an irradiation unit configured to emit an infrared ray toward an infusion tube; an imaging unit configured to generate a captured image obtained by imaging the infusion tube irradiated with the infrared ray by the irradiation unit; and a control unit configured to detect blockage of the infusion tube and air bubbles in the infusion tube based on a light intensity distribution in the captured image.
Claims17
A detection device comprising:
- an irradiation unit configured to emit an infrared ray toward an infusion tube;
- an imaging unit configured to generate a captured image obtained by imaging the infusion tube irradiated with the infrared ray by the irradiation unit;
- and
- a control unit configured to:
- determine a light intensity value of each pixel included in the captured image,
- specify high light intensity regions having a light intensity value equal to or more than a predetermined threshold as regions including opposing side wall portions of the infusion tube captured in the captured image based on a light intensity distribution in the captured image, and
- detect blockage of the infusion tube and air bubbles in the infusion tube based on the specified high light intensity regions.
